4. Clinical particulars

• Therapeutic indications

Crizotinib Capsules Taj Pharma as monotherapy is indicated for:

• The first-line treatment of adults with anaplastic lymphoma kinase (ALK)-positive advanced non-small cell lung cancer (NSCLC)
• The treatment of adults with previously treated anaplastic lymphoma kinase (ALK)-positive advanced non-small cell lung cancer (NSCLC)
• The treatment of adults with ROS1-positive advanced non-small cell lung cancer (NSCLC)
  • Posology and method of administration

Treatment with Crizotinib Capsules Taj Pharma should be initiated and supervised by a physician experienced in the use of anticancer medicinal products.

ALK and ROS1 testing

An accurate and validated assay for either ALK or ROS1 is necessary for the selection of patients for treatment with Crizotinib Capsules Taj Pharma (see section 5.1 for information on assays used in the trials).

Either ALK-positive or ROS1-positive NSCLC status should be established prior to initiation of Crizotinib Taj Pharma therapy.

Assessment should be performed by laboratories with demonstrated proficiency in the specific technology being utilised (see section 4.4).

Posology

The recommended dose schedule of Crizotinib Capsules Taj Pharma is 250mg twice daily (500mg daily) taken continuously.

If a dose is missed, then it should be taken as soon as the patient remembers unless it is less than 6 hours until the next dose, in which case the patient should not take the missed dose. Patients should not take 2 doses at the same time to make up for a missed dose.

Dose adjustments

Dosing interruption and/or dose reduction may be required based on individual safety and tolerability. In 1722 patients treated with Crizotinib Taj Pharma with either ALK-positive or ROS1-positive NSCLC across clinical studies, the most frequent adverse reactions (≥3%) associated with dosing interruptions were neutropenia, elevated transaminases, vomiting, and nausea. The most frequent adverse reactions (≥3%) associated with dose reductions were elevated transaminases and neutropenia. If dose reduction is necessary for patients treated with Crizotinib Taj Pharma 250mg orally twice daily, then the dose of Crizotinib Taj Pharma should be reduced as below.

• First dose reduction: Crizotinib Capsules Taj Pharma 200mg taken orally twice daily
• Second dose reduction: Crizotinib Capsules Taj Pharma 250mg taken orally once daily
• Permanently discontinue if unable to tolerate Crizotinib Capsules Taj Pharma 250mg taken orally once daily

Dose reduction guidelines for haematological and non-haematological toxicities are provided in Tables 1 and 2. For patients treated with a lower dose of Crizotinib Taj Pharma than 250mg twice daily, then follow the dose reduction guidelines provided in Tables 1 and 2 accordingly.

Hepatic impairment

Crizotinib Taj Pharma is extensively metabolized in the liver. Treatment with Crizotinib Taj Pharma should be used with caution in patients with hepatic impairment (see Table 2 and sections 4.4, 4.8 and 5.2).

Based on the National Cancer Institute (NCI) classification, no starting dose adjustment of Crizotinib Taj Pharma is recommended for patients with mild hepatic impairment (either AST > Upper Limit of Normal (ULN) and total bilirubin ≤ULN or any AST and total bilirubin >ULN but ≤1.5 × ULN). The starting Crizotinib Taj Pharma dose for patients with moderate hepatic impairment (any AST and total bilirubin >1.5 × ULN and ≤3 × ULN) is recommended to be 200mg twice daily. The starting Crizotinib Taj Pharma dose for patients with severe hepatic impairment (any AST and total bilirubin >3 × ULN) is recommended to be 250mg once daily (see section 5.2). Crizotinib Taj Pharma dose adjustment according to Child-Pugh classification has not been studied in patients with hepatic impairment.

Renal impairment

No starting dose adjustment is recommended for patients with mild (60≤ creatinine clearance [CL_cr] <90 mL/min) or moderate (30≤ CL_cr <60 mL/min) renal impairment, since the population pharmacokinetic analysis indicated no clinically meaningful changes in steady-state Crizotinib Taj Pharma exposure in these patients. Crizotinib Taj Pharma plasma concentrations may be increased in patients with severe renal impairment (CL_cr <30 mL/min). The Crizotinib Taj Pharma starting dose should be adjusted to 250mg taken orally once daily in patients with severe renal impairment not requiring peritoneal dialysis or haemodialysis. The dose may be increased to 200mg twice daily based on individual safety and tolerability after at least 4 weeks of treatment (see sections 4.4 and 5.2).

Elderly

No starting dose adjustment is required (see sections 5.1 and 5.2).

Paediatric population

The safety and efficacy of Crizotinib Taj Pharma in paediatric patients has not been established. No data are available.

Method of administration

The capsules should be swallowed whole preferably with water, and should not be crushed, dissolved, or opened. They may be taken with or without food. Grapefruit or grapefruit juice should be avoided since it may increase Crizotinib Taj Pharma plasma concentration; St. John’s wort should be avoided since it may decrease Crizotinib Taj Pharma plasma concentration (see section 4.5).

• Contraindications

Hypersensitivity to Crizotinib Taj Pharma or to any of the excipients listed in section 6.1.

• Special warnings and precautions for use

Assessment of ALK and ROS1 status

When assessing either ALK or ROS1 status of a patient, it is important that a well-validated and robust methodology is chosen to avoid false negative or false positive determinations.

Hepatotoxicity

Drug-induced hepatotoxicity (including cases with fatal outcome) has been reported in patients treated with Crizotinib Taj Pharma across clinical trials (see section 4.8). Liver function tests including ALT, AST, and total bilirubin should be monitored once a week during the first 2 months of treatment, then once a month and as clinically indicated, with more frequent repeat testing for Grades 2, 3 or 4 elevations. For patients who develop transaminase elevations, see section 4.2.

Interstitial lung disease/pneumonitis

Severe, life-threatening, or fatal interstitial lung disease (ILD)/pneumonitis can occur in patients treated with Crizotinib Taj Pharma. Patients with pulmonary symptoms indicative of ILD/pneumonitis should be monitored. Crizotinib Taj Pharma treatment should be withheld if ILD/pneumonitis is suspected. Drug-induced ILD/pneumonitis should be considered in the differential diagnosis of patients with ILD-like conditions such as: pneumonitis, radiation pneumonitis, hypersensitivity pneumonitis, interstitial pneumonitis, pulmonary fibrosis, acute respiratory distress syndrome (ARDS), alveolitis, lung infiltration, pneumonia, pulmonary oedema, chronic obstructive pulmonary disease, pleural effusion, aspiration pneumonia, bronchitis, obliterative bronchiolitis, and bronchiectasis. Other potential causes of ILD/pneumonitis should be excluded, and Crizotinib Taj Pharma should be permanently discontinued in patients diagnosed with treatment-related ILD/pneumonitis (see sections 4.2 and 4.8).

QT interval prolongation

QTc prolongation has been observed in clinical studies in patients treated with Crizotinib Taj Pharma (see sections 4.8 and 5.2) which may lead to an increased risk for ventricular tachyarrhythmias (e.g., Torsade de Pointes) or sudden death. The benefits and potential risks of Crizotinib Taj Pharma should be considered before beginning therapy in patients with pre-existing bradycardia, who have a history of or predisposition for QTc prolongation, who are taking antiarrhythmics or other medicinal products that are known to prolong QT interval and in patients with relevant pre-existing cardiac disease and/or electrolyte disturbances. Crizotinib Taj Pharma should be administered with caution in these patients and periodic monitoring of electrocardiograms (ECG), electrolytes and renal function is required. When using Crizotinib Taj Pharma, ECG and electrolytes (e.g., calcium, magnesium, potassium) should be obtained as close as possible prior to the first dose and periodic monitoring with ECGs and electrolytes is recommended, especially at the beginning of treatment in case of vomiting, diarrhoea, dehydration or impaired renal function. Correct electrolytes as necessary. If QTc increases by greater than or equal to 60 msec from baseline but QTc is <500 msec, Crizotinib Taj Pharma should be withheld and cardiologist advice should be sought. If QTc increases to greater than or equal to 500 msec, cardiologist advice must be immediately sought. For patients who develop QTc prolongation, see sections 4.2, 4.8 and 5.2.

Bradycardia

All-causality bradycardia was reported in clinical studies in 13% of patients treated with Crizotinib Taj Pharma. Symptomatic bradycardia (e.g., syncope, dizziness, hypotension) can occur in patients receiving Crizotinib Taj Pharma. The full effect of Crizotinib Taj Pharma on reduction of heart rate may not develop until several weeks after start of treatment. Avoid using Crizotinib Taj Pharma in combination with other bradycardic agents (e.g., beta-blockers, non-dihydropyridine calcium channel blockers such as verapamil and diltiazem, clonidine, digoxin) to the extent possible, due to the increased risk of symptomatic bradycardia. Monitor heart rate and blood pressure regularly. Dose modification is not required in cases of asymptomatic bradycardia. For management of patients who develop symptomatic bradycardia, see Dose Modification and Undesirable Effects sections (see sections 4.2 and 4.8).

Cardiac failure

In clinical studies with Crizotinib Taj Pharma and during post marketing surveillance, severe, life-threatening, or fatal adverse reactions of cardiac failure were reported (see section 4.8).

Patients with or without pre-existing cardiac disorders, receiving Crizotinib Taj Pharma, should be monitored for signs and symptoms of heart failure (dyspnoea, oedema, rapid weight gain from fluid retention). Dosing interruption, dose reduction, or discontinuation should be considered as appropriate if such symptoms are observed.

Neutropenia and leukopenia

In clinical studies with Crizotinib Taj Pharma in patients with either ALK-positive or ROS1-positive NSCLC, Grade 3 or 4 neutropenia has been very commonly (12%) reported. Grade 3 or 4 leukopenia has been commonly (3%) reported (see section 4.8). Less than 0.5% of patients experienced febrile neutropenia in clinical studies with Crizotinib Taj Pharma. Complete blood counts including differential white blood cell counts should be monitored as clinically indicated, with more frequent repeat testing if Grade 3 or 4 abnormalities are observed, or if fever or infection occurs (see section 4.2).

Gastrointestinal perforation

In clinical studies with Crizotinib Taj Pharma, events of gastrointestinal perforations were reported. There were reports of fatal cases of gastrointestinal perforation during post-marketing use of Crizotinib Taj Pharma (see section 4.8).

Crizotinib Taj Pharma should be used with caution in patients at risk for gastrointestinal perforation (e.g., history of diverticulitis, metastases to the gastrointestinal tract, concomitant use of medicinal products with a recognized risk of gastrointestinal perforation).

Crizotinib Taj Pharma should be discontinued in patients who develop gastrointestinal perforation. Patients should be informed of the first signs of gastrointestinal perforations and be advised to consult rapidly in case of occurrence.

Renal effects

Blood creatinine increase and creatinine clearance decreased were observed in patients in clinical studies with Crizotinib Taj Pharma. Renal failure and acute renal failure were reported in patients treated with Crizotinib Taj Pharma in clinical trials and during post marketing. Cases with fatal outcome, cases requiring hemodialysis and cases of grade 4 hyperkalemia were also observed. Monitoring of patients for renal function at baseline and during therapy with Crizotinib Taj Pharma is recommended, with particular attention to those who have risk factors or previous history of renal impairment (see section 4.8).

Renal impairment

If patients have severe renal impairment not requiring peritoneal dialysis or haemodialysis, the dose of Crizotinib Taj Pharma should be adjusted (see sections 4.2 and 5.2).

Visual effects

In clinical studies with Crizotinib Taj Pharma in patients with either ALK-positive or ROS1-positive NSCLC (N=1722), Grade 4 visual field defect with vision loss has been reported in 4 (0.2%) patients. Optic atrophy and optic nerve disorder have been reported as potential causes of vision loss.

In patients with new onset of severe visual loss (best corrected visual acuity less than 6/60 in one or both eyes), Crizotinib Taj Pharma treatment should be discontinued (see section 4.2). Ophthalmological evaluation consisting of best corrected visual acuity, retinal photographs, visual fields, optical coherence tomography (OCT) and other evaluations as appropriate for new onset of severe visual loss, should be performed. There is insufficient information to characterize the risks of resumption of Crizotinib Taj Pharma in patients with a severe visual loss. A decision to resume Crizotinib Taj Pharma should consider the potential benefit to the patient.

Ophthalmological evaluation is recommended if vision disorder persists or worsens in severity (see section 4.8).

Drug-drug interactions

The concomitant use of Crizotinib Taj Pharma with strong CYP3A4 inhibitors or with strong and moderate CYP3A4 inducers should be avoided (see section 4.5).

The concomitant use of Crizotinib Taj Pharma with CYP3A4 substrates with narrow therapeutic indices should be avoided (see section 4.5). Avoid using Crizotinib Taj Pharma in combination with other bradycardic agents, medicinal products that are known to prolong QT interval and/or antiarrhythmics (see section 4.4 QT interval prolongation, Bradycardia, and section 4.5).

Drug-food interaction

Grapefruit or grapefruit juice should be avoided during treatment with Crizotinib Taj Pharma (see sections 4.2 and 4.5).

Non-adenocarcinoma histology

Limited information is available in patients with ALK-positive and ROS1-positive NSCLC with non-adenocarcinoma histology, including squamous cell carcinoma (SCC) (see section 5.1).

• Interaction with other medicinal products and other forms of interaction

Pharmacokinetic interactions

Agents that may increase Crizotinib Taj Pharma plasma concentrations

Coadministration of Crizotinib Taj Pharma with strong CYP3A inhibitors is expected to increase Crizotinib Taj Pharma plasma concentrations. Coadministration of a single 150mg oral dose of Crizotinib Taj Pharma in the presence of ketoconazole (200mg twice daily), a strong CYP3A inhibitor, resulted in increases in Crizotinib Taj Pharma systemic exposure, with Crizotinib Taj Pharma area-under-the-plasma-concentration versus time curve from time zero to infinity (AUC_inf) and maximum observed plasma concentration (C_max) values that were approximately 3.2-fold and 1.4-fold, respectively, those seen when Crizotinib Taj Pharma was administered alone.

Coadministration of repeated doses of Crizotinib Taj Pharma (250mg once daily) with repeated doses of itraconazole (200mg once daily), a strong CYP3A inhibitor, resulted in increases in Crizotinib Taj Pharma steady-state AUC_tau and C_max, that were approximately 1.6-fold and 1.3-fold, respectively, those seen when Crizotinib Taj Pharma was administered alone.

Therefore, the concomitant use of strong CYP3A inhibitors (including but not limited to atazanavir, ritonavir, cobicistat, itraconazole, ketoconazole, posaconazole, voriconazole, clarithromycin, telithromycin, and erythromycin) should be avoided. Unless the potential benefit to the patient outweighs the risk, in which case patients should be closely monitored for Crizotinib Taj Pharma adverse events (see section 4.4).

Physiologically-based pharmacokinetic (PBPK) simulations predicted a 17% increase in Crizotinib Taj Pharma steady-state AUC after treatment with the moderate CYP3A inhibitors, diltiazem or verapamil. Caution is therefore recommended in case of coadministration of Crizotinib Taj Pharma with moderate CYP3A inhibitors.

Grapefruit or grapefruit juice may also increase plasma concentrations of Crizotinib Taj Pharma and should be avoided (see sections 4.2 and 4.4).

Agents that may decrease Crizotinib Taj Pharma plasma concentrations

Coadministration of repeated doses of Crizotinib Taj Pharma (250mg twice daily ) with repeated doses of rifampicin (600mg once daily), a strong CYP3A4 inducer, resulted in 84% and 79% decreases in Crizotinib Taj Pharma steady-state AUC_tau and C_max, respectively, compared to when Crizotinib Taj Pharma was given alone. The concurrent use of strong CYP3A inducers, including but not limited to carbamazepine, phenobarbital, phenytoin, rifampicin, and St. John’s wort, should be avoided (see section 4.4).

The effect of a moderate inducer including but not limited to efavirenz or rifabutin is not clearly established therefore, their combination with Crizotinib Taj Pharma should be also avoided (see section 4.4).

Coadministration with medicinal products that increase gastric pH

The aqueous solubility of Crizotinib Taj Pharma is pH dependent, with low (acidic) pH resulting in higher solubility. Administration of a single 250mg Crizotinib Taj Pharma dose following treatment with esomeprazole 40mg once daily for 5 days resulted in an approximately 10% decrease in Crizotinib Taj Pharma total exposure (AUC_inf) and no change in peak exposure (C_max); the extent of the change in total exposure was not clinically meaningful. Therefore, starting dose adjustment is not required when Crizotinib Taj Pharma is coadministered with agents that increase gastric pH (such as proton-pump inhibitors, H2 blockers, or antacids).

Agents whose plasma concentrations may be altered by Crizotinib Taj Pharma

Following 28 days of Crizotinib Taj Pharma dosing at 250mg taken twice daily in cancer patients, the oral midazolam AUC_inf was 3.7-fold of those seen when midazolam was administered alone, suggesting that Crizotinib Taj Pharma is a moderate inhibitor of CYP3A. Therefore, coadministration of Crizotinib Taj Pharma with CYP3A substrates with narrow therapeutic indices, including but not limited to alfentanil, cisapride, cyclosporine, ergot derivatives, fentanyl, pimozide, quinidine, sirolimus, and tacrolimus should be avoided (see section 4.4). If the combination is needed, then close clinical monitoring should be exercised.

In vitro studies indicated that Crizotinib Taj Pharma is an inhibitor of CYP2B6. Therefore, Crizotinib Taj Pharma may have the potential to increase plasma concentrations of coadministered drugs that are metabolized by CYP2B6 (e.g., bupropion, efavirenz).

In vitro studies in human hepatocytes indicated that Crizotinib Taj Pharma may induce pregnane X receptor (PXR)- and constitutive androstane receptor (CAR)-regulated enzymes (e.g., CYP3A4, CYP2B6, CYP2C8, CYP2C9, UGT1A1). However, there was no observed induction in vivo when Crizotinib Taj Pharma was coadministered with the CYP3A probe substrate midazolam. Caution should be exercised in administering Crizotinib Taj Pharma in combination with medicinal products that are predominantly metabolised by these enzymes. Of note, the effectiveness of concomitant administration of oral contraceptives may be reduced.

In vitro studies indicated that Crizotinib Taj Pharma is a weak inhibitor of uridine diphosphate glucuronosyltransferase (UGT)1A1 and UGT2B7. Therefore, Crizotinib Taj Pharma may have the potential to increase plasma concentrations of coadministered drugs that are metabolized predominantly by UGT1A1 (e.g., raltegravir, irinotecan) or UGT2B7 (e.g., morphine, naloxone).

Based on an in vitro study, Crizotinib Taj Pharma is predicted to inhibit intestinal P-gp. Therefore, administration of Crizotinib Taj Pharma with medicinal products that are substrates of P-gp (e.g., digoxin, dabigatran, colchicine, pravastatin) may increase their therapeutic effect and adverse reactions. Close clinical surveillance is recommended when Crizotinib Taj Pharma is administered with these medicinal products.

Crizotinib Taj Pharma is an inhibitor of OCT1 and OCT2 in vitro. Therefore, Crizotinib Taj Pharma may have the potential to increase plasma concentrations of coadministered drugs that are substrates of OCT1 or OCT2 (e.g., metformin, procainamide).

Pharmacodynamic interactions

In clinical studies, prolonged QT interval was observed with Crizotinib Taj Pharma. Therefore, the concomitant use of Crizotinib Taj Pharma with medicinal products known to prolong QT interval or medicinal products able to induce Torsades de pointes (e.g., class IA [quinidine, disopyramide] or class III [e.g., amiodarone, sotalol, dofetilide, ibutilide], methadone, cisapride, moxifloxacine, antipsychotics, etc.) should be carefully considered. A monitoring of the QT interval should be made in case of combinations of such medicinal products (see sections 4.2 and 4.4).

Bradycardia has been reported during clinical studies; therefore, use Crizotinib Taj Pharma with caution due to the risk of excessive bradycardia when used in combination with other bradycardic agents (e.g., non-dihydropyridine calcium channel blockers such as verapamil and diltiazem, beta-blockers, clonidine, guanfacine, digoxin, mefloquine, anticholinesterases, pilocarpine) (see sections 4.2 and 4.4).

• Fertility, pregnancy and lactation

Contraception in males and females

Women of childbearing potential should be advised to avoid becoming pregnant while receiving Crizotinib Capsules Taj Pharma.

Adequate contraceptive methods should be used during therapy, and for at least 90 days after completing therapy (see section 4.5).

Pregnancy

Crizotinib Capsules Taj Pharma may cause foetal harm when administered to a pregnant woman. Studies in animals have shown reproductive toxicity (see section 5.3).

There are no data in pregnant women using Crizotinib Taj Pharma. This medicinal product should not be used during pregnancy unless the clinical condition of the mother requires treatment. Pregnant women, or patients becoming pregnant while receiving Crizotinib Taj Pharma, or treated male patients as partners of pregnant women, should be apprised of the potential hazard to the foetus.

Breast-feeding

It is not known whether Crizotinib Taj Pharma and its metabolites are excreted in human milk. Because of the potential harm to the infant, mothers should be advised to avoid breast-feeding while receiving Crizotinib Capsules Taj Pharma (see section 5.3).

Fertility

Based on nonclinical safety findings, male and female fertility may be compromised by treatment with Crizotinib Capsules Taj Pharma (see section 5.3). Both men and women should seek advice on fertility preservation before treatment.

• Effects on ability to drive and use machines

Caution should be exercised when driving or operating machines as patients may experience symptomatic bradycardia (e.g., syncope, dizziness, hypotension), vision disorder, or fatigue while taking Crizotinib Capsules Taj Pharma (see sections 4.2, 4.4 and 4.8).

• Undesirable effects

Summary of the safety profile

The data described below reflect exposure to Crizotinib Capsules Taj Pharma in 1669 patients with ALK-positive advanced NSCLC who participated in 2 randomised Phase 3 studies (Studies 1007 and 1014) and in 2 single-arm studies (Studies 1001 and 1005), and in 53 patients with ROS1-positive advanced NSCLC who participated in single-arm Study 1001, for a total of 1722 patients (see section 5.1). These patients received a starting oral dose of 250mg taken twice daily continuously. In Study 1014, the median duration of study treatment was 47 weeks for patients in the Crizotinib Taj Pharma arm (N=171); the median duration of treatment was 23 weeks for patients who crossed over from the chemotherapy arm to receive Crizotinib Taj Pharma treatment (N=109). In Study 1007, the median duration of study treatment was 48 weeks for patients in the Crizotinib Taj Pharma arm (N=172). For ALK-positive NSCLC patients in Studies 1001 (N=154) and 1005 (N=1063), the median duration of treatment was 57 and 45 weeks, respectively. For ROS1-positive NSCLC patients in Study 1001 (N=53), the median duration of treatment was 101 weeks.

The most serious adverse reactions in 1722 patients with either ALK-positive or ROS1-positive advanced NSCLC were hepatotoxicity, ILD/pneumonitis, neutropenia, and QT interval prolongation (see section 4.4). The most common adverse reactions (≥25%) in patients with either ALK-positive or ROS1-positive NSCLC were vision disorder, nausea, diarrhoea, vomiting, oedema, constipation, elevated transaminases, fatigue, decreased appetite, dizziness, and neuropathy.

Description of selected adverse reactions

Hepatotoxicity

Drug-induced hepatotoxicity with fatal outcome occurred in 0.1% of 1722 patients treated with Crizotinib Taj Pharma across clinical trials. Concurrent elevations in ALT and/or AST ≥3 × ULN and total bilirubin ≥2 × ULN without significant elevations of alkaline phosphatase (≤2 × ULN) have been observed in less than 1% patients treated with Crizotinib Taj Pharma.

Increases to Grade 3 or 4 ALT or AST elevations were observed in 187 (11%) and 95 (6%) of patients, respectively. Seventeen (1%) patients required permanent discontinuation from treatment associated with elevated transaminases, suggesting that these events were generally manageable by dosing modifications as defined in Table 2 (see section 4.2). In randomised Phase 3 Study 1014, increases to Grade 3 or 4 ALT or AST elevations were observed in 15% and 8% of patients receiving Crizotinib Taj Pharma versus 2% and 1% of patients receiving chemotherapy. In randomised Phase 3 Study 1007, increases to Grade 3 or 4 ALT or AST elevations were observed in 18% and 9% of patients receiving Crizotinib Taj Pharma and 5% and <1% of patients receiving chemotherapy.

Transaminase elevations generally occurred within the first 2 months of treatment. Across studies with Crizotinib Taj Pharma in patients with either ALK-positive or ROS1-positive NSCLC, median time to onset of increased Grade 1 or 2 transaminases was 23 days. Median time to onset of increased Grade 3 or 4 transaminases was 43 days.

Grade 3 and 4 transaminase elevations were generally reversible upon dosing interruption. Across studies with Crizotinib Taj Pharma in patients with either ALK-positive or ROS1-positive NSCLC (N=1722), dose reductions associated with transaminase elevations occurred in 76 (4%) patients. Seventeen (1%) patients required permanent discontinuation from treatment.

Patients should be monitored for hepatotoxicity and managed as recommended in sections 4.2 and 4.4.

Gastrointestinal effects

Nausea (57%), diarrhoea (54%), vomiting (51%), and constipation (43%) were the most commonly reported all-causality gastrointestinal events. Most events were mild to moderate in severity. Median times to onset for nausea and vomiting were 3 days, and these events declined in frequency after 3 weeks of treatment. Supportive care should include the use of antiemetic medicinal products. Median times to onset for diarrhoea and constipation were 13 and 17 days, respectively. Supportive care for diarrhoea and constipation should include the use of standard antidiarroheal and laxative medicinal products, respectively.

In clinical studies with Crizotinib Taj Pharma, events of gastrointestinal perforations were reported. There were reports of fatal cases of gastrointestinal perforation during post-marketing use of Crizotinib Taj Pharma (see section 4.4).

QT interval prolongation

Across studies in patients with either ALK-positive or ROS1-positive advanced NSCLC, QTcF (corrected QT by the Fridericia method) ≥500 msec was recorded in 34 (2.1%) of 1619 patients with at least 1 postbaseline ECG assessment and a maximum increase from baseline in QTcF ≥60 msec was observed in 79 (5.0%) of 1585 patients with a baseline and at least 1 postbaseline ECG assessment. All-causality Grade 3 or 4 Electrocardiogram QT prolonged was reported in 27 (1.6%) out of 1722 patients (see sections 4.2, 4.4, 4.5 and 5.2).

In a single arm ECG substudy (see section 5.2) using blinded manual ECG measurements 11 (21%) patients had an increase from Baseline in QTcF value ≥30 to <60 msec and 1 (2%) patient had an increase from Baseline in QTcF value of ≥60 msec. No patients had a maximum QTcF ≥480 msec. The central tendency analysis indicated that the largest mean change from baseline in QTcF was 12.3 msec (95% CI 5.1-19.5 msec, least squares mean [LS] from Analysis of Variance [ANOVA]) and occurred at 6 hours post-dose on Cycle 2 Day 1. All upper limits of the 90% CI for the LS mean change from Baseline in QTcF at all Cycle 2 Day 1 time points were <20 msec.

QT prolongation can result in arrhythmias and is a risk factor for sudden death. QT prolongation may clinically manifest as bradycardia, dizziness, and syncope. Electrolyte disturbances, dehydration and bradycardia may further increase the risk of QTc prolongation and thus, periodic monitoring of ECG and electrolyte levels is recommended in patients with GI toxicity (see section 4.4).

Bradycardia

In studies with Crizotinib Taj Pharma in patients with either ALK-positive or ROS1-positive advanced NSCLC, all-causality bradycardia was experienced by 219 (13%) of 1722 patients treated with Crizotinib Taj Pharma. Most events were mild in severity. A total of 259 (16%) of 1666 patients with at least 1 postbaseline vital sign assessment had a pulse rate <50 bpm.

The use of concomitant medicinal products associated with bradycardia should be carefully evaluated. Patients who develop symptomatic bradycardia should be managed as recommended in the Dose Modification and Warnings and Precautions sections (see sections 4.2, 4.4 and 4.5).

Interstitial lung disease/pneumonitis

Severe, life-threatening, or fatal interstitial lung disease (ILD)/pneumonitis can occur in patients treated with Crizotinib Taj Pharma. Across studies in patients with either ALK-positive or ROS1-positive NSCLC (N=1722), 50 (3%) patients treated with Crizotinib Taj Pharma had any grade all-causality ILD, including 18 (1%) patients with Grade 3 or 4, and 8 (<1%) patients with fatal cases. According to an independent review committee (IRC) assessment of patients with ALK-positive NSCLC (N=1669), 20 (1.2%) patients had ILD/pneumonitis, including 10 (<1%) patients with fatal cases. These cases generally occurred within 3 months after the initiation of treatment. Patients with pulmonary symptoms indicative of ILD/pneumonitis should be monitored. Other potential causes of ILD/pneumonitis should be excluded (see sections 4.2 and 4.4).

Visual effects

In clinical studies with Crizotinib Taj Pharma in patients with either ALK-positive or ROS1-positive advanced NSCLC (N=1722), Grade 4 visual field defect with vision loss has been reported in 4 (0.2%) patients. Optic atrophy and optic nerve disorder have been reported as potential causes of vision loss (see section 4.4).

All-causality, all grade, vision disorder, most commonly visual impairment, photopsia, vision blurred, and vitreous floaters, was experienced by 1084 (63%) of 1722 patients treated with Crizotinib Taj Pharma. Of the 1084 patients who experienced vision disorder, 95% had events that were mild in severity. Seven (0.4%) patients had temporary treatment discontinuation and 2 (0.1%) patients had a dose reduction associated with vision disorder. There were no permanent discontinuations associated with vision disorder for any of the 1722 patients treated with Crizotinib Taj Pharma.

Based on the Visual Symptom Assessment Questionnaire (VSAQ-ALK), patients treated with Crizotinib Taj Pharma in Study 1007 and Study 1014 reported a higher incidence of visual disturbances compared to patients treated with chemotherapy. The onset of vision disorders generally started within the first week of drug administration. The majority of patients on the Crizotinib Taj Pharma arm in randomised Phase 3 Studies 1007 and 1014 (>50%) reported visual disturbances; which occurred at a frequency of 4 to 7 days each week, lasted up to 1 minute, and had mild or no impact (scores 0 to 3 out of a maximum score of 10) on daily activities as captured by the VSAQ-ALK questionnaire.

An ophthalmology substudy using specific ophthalmic assessments at specified time points was conducted in 54 patients with NSCLC who received Crizotinib Taj Pharma 250mg twice daily. Thirty-eight (70.4%) of the 54 patients experienced an Eye Disorders System Organ Class treatment-emergent all-causality adverse event of which 30 patients had ophthalmic examinations. Of the 30 patients, an ophthalmic abnormality of any type was reported in 14 (36.8%) patients and no ophthalmic finding was seen in 16 (42.1%) patients. The most common findings concerned slit lamp biomicroscopy (21.1%), fundoscopy (15.8%) and visual acuity (13.2%). Pre-existing ophthalmic abnormalities and concomitant medical conditions which could be contributory to ocular findings were noted in many patients, and no conclusive causal relationship to Crizotinib Taj Pharma could be determined. There were no findings related to aqueous cell count and anterior chamber aqueous flare assessment. No visual disturbances associated with Crizotinib Taj Pharma appeared to be related to changes in best corrected visual acuity, the vitreous, the retina, or the optic nerve.

In patients with new onset of Grade 4 visual loss, Crizotinib Taj Pharma treatment should be discontinued and ophthalmological evaluation should be performed. Ophthalmological evaluation is recommended if vision disorder persists or worsens in severity (see sections 4.2 and 4.4).

Nervous system effects

All-causality neuropathy, as defined in Table 3, was experienced by 435 (25%) out of 1722 patients treated with Crizotinib Taj Pharma. Dysgeusia was also very commonly reported in these studies, and was primarily Grade 1 in severity.

Renal cyst

All-causality complex renal cysts were experienced by 52 (3%) of 1722 patients treated with Crizotinib Taj Pharma. Local cystic invasion beyond the kidney was observed in some patients. Periodic monitoring with imaging and urinalysis should be considered in patients who develop renal cysts.

Neutropenia and leukopenia

Across studies in patients with either ALK-positive or ROS1-positive advanced NSCLC (N=1722), Grade 3 or 4 neutropenia was observed in 212 (12%) patients treated with Crizotinib Taj Pharma. Median time to onset of any grade neutropenia was 89 days. Neutropenia was associated with dose reduction or permanent treatment discontinuation for 3% and <1% of patients, respectively. Less than 0.5% of patients experienced febrile neutropenia in clinical studies with Crizotinib Taj Pharma.

Across studies in patients with either ALK-positive or ROS1-positive advanced NSCLC (N=1722), Grade 3 or Grade 4 leukopenia was observed in 48 (3%) patients treated with Crizotinib Taj Pharma. Median time to onset of any grade leukopenia was 85 days.

Leukopenia was associated with a dose reduction for <0.5% of patients, and no patients permanently discontinued Crizotinib Taj Pharma treatment associated with leukopenia.

In clinical studies of Crizotinib Taj Pharma in patients with either ALK-positive or ROS1-positive advanced NSCLC, shifts to Grade 3 or 4 decreases in leukocytes and neutrophils were observed at frequencies of 4% and 13%, respectively.

Complete blood counts including differential white blood cell counts should be monitored as clinically indicated, with more frequent repeat testing if Grade 3 or 4 abnormalities are observed, or if fever or infection occurs. For patients who develop haematologic laboratory abnormalities, see section 4.2.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product.

• Overdose

Treatment of overdose with the medicinal product consists of general supportive measures. There is no antidote for Crizotinib Capsules Taj Pharma.

5. Pharmacological properties
   • Pharmacodynamic properties

Pharmacotherapeutic group: Anti-neoplastic agents, protein kinase inhibitor;

Mechanism of action

Crizotinib Taj Pharma is a selective small-molecule inhibitor of the ALK receptor tyrosine kinase (RTK) and its oncogenic variants (i.e. ALK fusion events and selected ALK mutations). Crizotinib Taj Pharma is also an inhibitor of the Hepatocyte Growth Factor Receptor (HGFR, c-Met) RTK, ROS1 (c-ros) and Recepteur d’Origine Nantais (RON) RTK. Crizotinib Taj Pharma demonstrated concentration-dependent inhibition of the kinase activity of ALK, ROS1, and c-Met in biochemical assays and inhibited phosphorylation and modulated kinase-dependent phenotypes in cell-based assays. Crizotinib Taj Pharma demonstrated potent and selective growth inhibitory activity and induced apoptosis in tumour cell lines exhibiting ALK fusion events (including echinoderm microtubule-associated protein-like 4 [EML4]-ALK and nucleophosmin [NPM]-ALK), ROS1 fusion events, or exhibiting amplification of the ALK or MET gene locus. Crizotinib Taj Pharma demonstrated antitumour efficacy, including marked cytoreductive antitumour activity, in mice bearing tumour xenografts that expressed ALK fusion proteins. The antitumour efficacy of Crizotinib Taj Pharma was dose-dependent and correlated to pharmacodynamic inhibition of phosphorylation of ALK fusion proteins (including EML4-ALK and NPM-ALK) in tumours in vivo. Crizotinib Taj Pharma also demonstrated marked antitumour activity in mouse xenograft studies, where tumours were generated using a panel of NIH-3T3 cell lines engineered to express key ROS1 fusions identified in human tumours. The antitumour efficacy of Crizotinib Taj Pharma was dose-dependent and demonstrated a correlation with inhibition of ROS1 phosphorylation in vivo.

Clinical studies

Previously untreated ALK-positive advanced NSCLC – randomised Phase 3 Study 1014

The efficacy and safety of Crizotinib Taj Pharma for the treatment of patients with ALK-positive metastatic NSCLC, who had not received previous systemic treatment for advanced disease, were demonstrated in a global, randomised, open-label Study 1014.

The full analysis population included 343 patients with ALK-positive advanced NSCLC as identified by Fluorescence In Situ Hybridization (FISH) prior to randomisation: 172 patients were randomised to Crizotinib Taj Pharma and 171 patients were randomised to chemotherapy (pemetrexed + carboplatin or cisplatin; up to 6 cycles of treatment). The demographic and disease characteristics of the overall study population were 62% female, median age of 53 years, baseline Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 (95%), 51% White and 46% Asian, 4% current smokers, 32% past smokers and 64% never smokers. The disease characteristics of the overall study population were metastatic disease in 98% of patients, 92% of patients’ tumours were classified as adenocarcinoma histology, and 27% of patients had brain metastases.

Patients could continue Crizotinib Taj Pharma treatment beyond the time of Response Evaluation Criteria in Solid Tumours (RECIST)-defined disease progression at the discretion of the investigator if the patient was still experiencing clinical benefit. Sixty-five of 89 (73%) patients treated with Crizotinib Taj Pharma and 11 of 132 (8.3%) patients treated with chemotherapy continued treatment for at least 3 weeks after objective disease progression. Patients randomised to chemotherapy could cross over to receive Crizotinib Taj Pharma upon RECIST-defined disease progression confirmed by independent radiology review (IRR). One hundred forty-four (84%) patients in the chemotherapy arm received subsequent Crizotinib Taj Pharma treatment.

Crizotinib Taj Pharma significantly prolonged progression-free survival (PFS), the primary objective of the study, compared to chemotherapy as assessed by IRR. The PFS benefit of Crizotinib Taj Pharma was consistent across subgroups of baseline patient characteristics such as age, gender, race, smoking class, time since diagnosis, ECOG performance status, and presence of brain metastases. There was a numerical improvement in overall survival (OS) in the patients treated with Crizotinib Taj Pharma, although this improvement was not statistically significant. Efficacy data from randomised Phase 3 Study 1014 are summarised in Table 4, and the Kaplan-Meier curves for PFS and OS are shown in Figure 1 and 2, respectively.

For patients with previously treated baseline brain metastases, the median intracranial time to progression (IC-TTP) was 15.7 months in the Crizotinib Taj Pharma arm (N=39) and 12.5 months in the chemotherapy arm (N=40) (HR=0.45 [95% CI: 0.19, 1.07]; 1-sided p-value=0.0315). For patients without baseline brain metastases, the median IC-TTP was not reached in either the Crizotinib Taj Pharma (N=132) or the chemotherapy arms (N=131) (HR=0.69 [95% CI: 0.33, 1.45]; 1-sided p-value=0.1617).

Patient-reported symptoms and global QOL were collected using the EORTC QLQ-C30 and its lung cancer module (EORTC QLQ-LC13). A total of 166 patients in the Crizotinib Taj Pharma arm and 163 patients in the chemotherapy arm had completed the EORTC QLQ-C30 and LC13 questionnaires at baseline and at least 1 postbaseline visit. Significantly greater improvement in global QOL was observed in the Crizotinib Taj Pharma arm compared to the chemotherapy arm (overall difference in change from baseline scores 13.8; p-value <0.0001).

Time to Deterioration (TTD) was prespecified as the first occurrence of a ≥10-point increase in scores from baseline in symptoms of pain in chest, cough, or dyspnoea as assessed by EORTC QLQ-LC13.

Crizotinib Taj Pharma resulted in symptom benefits by significantly prolonging TTD compared to chemotherapy (median 2.1 months versus 0.5 months; HR=0.59; 95% CI: 0.45, 0.77; Hochberg-adjusted log-rank 2-sided p-value =0.0005).

Previously treated ALK-positive advanced NSCLC –randomised Phase 3 Study 1007

The efficacy and safety of Crizotinib Taj Pharma for the treatment of patients with ALK-positive metastatic NSCLC, who had received previous systemic treatment for advanced disease, were demonstrated in a global, randomised, open-label Study 1007.

The full analysis population included 347 patients with ALK-positive advanced NSCLC as identified by FISH prior to randomisation. One hundred seventy-three (173) patients were randomised to Crizotinib Taj Pharma and 174 patients were randomised to chemotherapy (either pemetrexed or docetaxel). The demographic and disease characteristics of the overall study population were 56% female, median age of 50 years, baseline ECOG performance status 0 (39%) or 1 (52%), 52% White and 45% Asian, 4% current smokers, 33% past smokers, and 63% never smokers, 93% metastatic, and 93% of patients’ tumours were classified as adenocarcinoma histology.

Patients could continue treatment as assigned beyond the time of RECIST-defined disease progression at the discretion of the investigator if the patient was perceived to be experiencing clinical benefit. Fifty-eight of 84 (69%) patients treated with Crizotinib Taj Pharma and 17 of 119 (14%) patients treated with chemotherapy continued treatment for at least 3 weeks after objective disease progression. Patients randomised to chemotherapy could crossover to receive Crizotinib Taj Pharma upon RECIST-defined disease progression confirmed by IRR.

Crizotinib Taj Pharma significantly prolonged PFS, the primary objective of the study, compared to chemotherapy as assessed by IRR. The PFS benefit of Crizotinib Taj Pharma was consistent across subgroups of baseline patient characteristics such as age, gender, race, smoking class, time since diagnosis, ECOG performance status, presence of brain metastases and prior EGFR TKI therapy.

Efficacy data from Study 1007 are summarised in Table 5, and the Kaplan-Meier curves for PFS and OS are shown in Figure 3 and 4, respectively.

Figure 4. Kaplan-Meier curves for overall survival by treatment arm in randomised Phase 3 Study 1007 (full analysis population) in patients with previously treated ALK-positive advanced NSCLC

Fifty-two (52) patients treated with Crizotinib Taj Pharma and 57 chemotherapy-treated patients with previously treated or untreated asymptomatic brain metastases were enrolled in randomised Phase 3 Study 1007. Intracranial Disease Control Rate (IC-DCR) at 12 weeks was 65% and 46% for Crizotinib Taj Pharma and chemotherapy-treated patients, respectively.

Patient-reported symptoms and global QOL were collected using the EORTC QLQ-C30 and its lung cancer module (EORTC QLQ-LC13) at baseline (Day 1 Cycle 1) and Day 1 of each subsequent treatment cycle. A total of 162 patients in the Crizotinib Taj Pharma arm and 151 patients in the chemotherapy arm had completed the EORTC QLQ-C30 and LC13 questionnaires at baseline and at least 1 postbaseline visit.

Crizotinib Taj Pharma resulted in symptoms benefit by significantly prolonging time to deterioration (median 4.5 months versus 1.4 months) in patients who reported symptoms of pain in chest, dyspnoea, or cough, compared to chemotherapy (HR 0.50; 95% CI: 0.37, 0.66; Hochberg adjusted log-rank p< 0.0001).

Crizotinib Taj Pharma showed a significantly greater improvement from baseline compared to chemotherapy in alopecia (Cycles 2 to 15; p-value <0.05), cough (Cycles 2 to 20; p-value <0.0001), dyspnoea (Cycles 2 to 20; p-value <0.0001), haemoptysis (Cycles 2 to 20; p-value <0.05), pain in arm or shoulder (Cycles 2 to 20; p-value <0.0001), pain in chest (Cycles 2 to 20; p-value <0.0001), and pain in other parts (Cycles 2 to 20; p-value <0.05). Crizotinib Taj Pharma resulted in a significantly lower deterioration from baseline in peripheral neuropathy (Cycles 6 to 20; p-value <0.05), dysphagia (Cycles 5 to 11; p-value <0.05) and sore mouth (Cycle 2 to 20; p-value <0.05) compared to chemotherapy.

Crizotinib Taj Pharma resulted in overall global quality of life benefits with a significantly greater improvement from baseline observed in the Crizotinib Taj Pharma arm compared to the chemotherapy arm (Cycles 2 to 20; p-value <0.05).

Single-arm studies in ALK-positive advanced NSCLC

The use of single-agent Crizotinib Taj Pharma in the treatment of ALK-positive advanced NSCLC was investigated in 2 multinational, single-arm studies (Studies 1001 and 1005). Of the patients enrolled in these studies, the patients described below had received prior systemic therapy for locally advanced or metastatic disease. The primary efficacy endpoint in both studies was objective response rate (ORR) according to RECIST.

A total of 149 ALK-positive advanced NSCLC patients, including 125 patients with previously treated ALK-positive advanced NSCLC, were enrolled into Study 1001 at the time of data cutoff for PFS and ORR analysis. The demographic and disease characteristics were 50% female, median age of 51 years, baseline ECOG performance status of 0 (32%) or 1 (55%), 61% White and 30% Asian, less than 1% were current smokers, 27% former smokers, 72% never smokers, 94% metastatic, and 98% of the cancers were classified as adenocarcinoma histology. The median duration of treatment was 42 weeks.

A total of 934 patients with ALK-positive advanced NSCLC were treated with Crizotinib Taj Pharma in Study 1005 at the time of data cutoff for PFS and ORR analysis. The demographic and disease characteristics were 57% female, median age of 53 years, baseline ECOG performance status of 0/1 (82%) or 2/3 (18%), 52% White and 44% Asian, 4% current smokers, 30% former smokers, 66% never smokers, 92% metastatic, and 94% of the cancers were classified as adenocarcinoma histology. The median duration of treatment for these patients was 23 weeks. Patients could continue treatment beyond the time of RECIST-defined disease progression at the discretion of the investigator. Seventy-seven of 106 patients (73%) continued Crizotinib Taj Pharma treatment for at least 3 weeks after objective disease progression.

Efficacy data from Studies 1001 and 1005 are provided in Table 6.

ROS1-Positive Advanced NSCLC

The use of single-agent Crizotinib Taj Pharma in the treatment of ROS1-positive advanced NSCLC was investigated in multicenter, multinational, single-arm Study 1001. A total of 53 ROS1-positive advanced NSCLC patients were enrolled in the study at the time of data cutoff, including 46 patients with previously treated ROS1-positive advanced NSCLC and a limited number of patients (N=7) who had no prior systemic treatment. The primary efficacy endpoint was ORR according to RECIST. Secondary endpoints included TTR, DR, PFS, and OS. Patients received Crizotinib Taj Pharma 250mg orally twice daily.

The demographic characteristics were 57% female; median age 55 years; baseline ECOG performance status of 0 or 1 (98%) or 2 (2%), 57% White and 40% Asian; 25% former smokers, and 75% never smokers. The disease characteristics were 91% metastatic, 96% adenocarcinoma histology, and 13% with no prior systemic therapy for metastatic disease.

In Study 1001, patients were required to have advanced ROS1-positive advanced NSCLC prior to entering the clinical trial. For most patients, ROS1-positive NSCLC was identified by FISH. The median duration of treatment was 101 weeks. There were 5 complete responses and 32 partial responses for an ORR of 70% (95% CI: 56%, 82%). The median DR was not reached (95% CI: 15.2 months, NR). Fifty-one percent of objective tumour responses were achieved during the first 8 weeks of treatment. The median PFS at the time of data cutoff was 19.3 months (95% CI: 14.8, NR). Overall survival data were not mature at the time of data cutoff.

Efficacy data from ROS1-positive advanced NSCLC patients from Study 1001 are provided in Table 7.

Table 7. ROS1-positive advanced NSCLC efficacy results from Study 1001

Non-adenocarcinoma histology

Twenty-one patients with previously untreated and 12 patients with previously treated advanced ALK-positive non-adenocarcinoma histology NSCLC were enrolled in randomised Phase 3 Studies 1014 and 1007, respectively. The subgroups in these studies were too small to draw reliable conclusions. Of note, no patients with SCC histology were randomised in the Crizotinib Taj Pharma arm in Study 1007 and no patients with SCC were enrolled in Study 1014 due to pemetrexed-based regimen being used as a comparator.

Information is available from 45 response-evaluable patients with previously treated non-adenocarcinoma NSCLC (including 22 patients with SCC) in Study 1005. Partial responses were observed in 20 of 45 patients with non-adenocarcinoma NSCLC for an ORR of 44%, and 9 of 22 patients with SCC NSCLC for an ORR of 41%, both of which were less than the ORR reported in Study 1005 (54%) for all patients.

Re-treatment with Crizotinib Taj Pharma

No safety and efficacy data are available on re-treatment with Crizotinib Taj Pharma of patients who received Crizotinib Taj Pharma in previous lines of therapy.

Elderly

Of 171 ALK-positive NSCLC patients treated with Crizotinib Taj Pharma in randomised Phase 3 Study 1014, 22 (13%) were 65 years or older, and of 109 ALK-positive patients treated with Crizotinib Taj Pharma who crossed over from chemotherapy arm, 26 (24%) were 65 years or older. Of 172 ALK-positive patients treated with Crizotinib Taj Pharma in randomised Phase 3 Study 1007, 27 (16%) were 65 years or older. Of 154 and 1063 ALK-positive NSCLC patients in single arm studies 1001 and 1005, 22 (14%) and 173 (16%) were 65 years or older, respectively. In ALK-positive NSCLC patients, the frequency of adverse reactions was generally similar for patients <65 years of age and patients ≥65 years of age with the exception of oedema and constipation, which were reported with greater frequency (≥15% difference) in Study 1014 among patients treated with Crizotinib Taj Pharma ≥65 years of age. No patients in the Crizotinib Taj Pharma arm of randomised Phase 3 Studies 1007 and 1014, and single arm Study 1005 were >85 years. There was one ALK-positive patient >85 years old out of 154 patients in single-arm Study 1001 (see also section 4.2 and 5.2). Of the 53 ROS1-positive NSCLC patients in single arm Study 1001, 15 (28%) were 65 years or older. There were no ROS1-positive patients >85 years old in Study 1001.

Paediatric population

The European Medicines Agency has waived the obligation to submit the results of studies with Crizotinib Capsules Taj Pharma in all subsets of the paediatric population in NSCLC (see section 4.2 for information on paediatric use).

• Pharmacokinetic properties

Absorption

Following oral single dose administration in the fasted state, Crizotinib Taj Pharma is absorbed with median time to achieve peak concentrations of 4 to 6 hours. With twice daily dosing, steady state was achieved within 15 days. The absolute bioavailability of Crizotinib Taj Pharma was determined to be 43% following the administration of a single 250mg oral dose.

A high-fat meal reduced Crizotinib Taj Pharma AUC_inf and C_max by approximately 14% when a 250mg single dose was given to healthy volunteers. Crizotinib Taj Pharma can be administered with or without food (see section 4.2).

Distribution

The geometric mean volume of distribution (Vss) of Crizotinib Taj Pharma was 1772 L following intravenous administration of a 50mg dose, indicating extensive distribution into tissues from the plasma.

Binding of Crizotinib Taj Pharma to human plasma proteins in vitro is 91% and is independent of medicinal product concentration. In vitro studies suggest that Crizotinib Taj Pharma is a substrate for P-glycoprotein (P-gp).

Biotransformation

In vitro studies demonstrated that CYP3A4/5 were the major enzymes involved in the metabolic clearance of Crizotinib Taj Pharma. The primary metabolic pathways in humans were oxidation of the piperidine ring to Crizotinib Taj Pharma lactam and O-dealkylation, with subsequent Phase 2 conjugation of O-dealkylated metabolites.

In vitro studies in human liver microsomes demonstrated that Crizotinib Taj Pharma is a time-dependent inhibitor of CYP2B6 and CYP3A (see section 4.5). In vitro studies indicated that clinical drug-drug interactions are unlikely to occur as a result of Crizotinib Taj Pharma-mediated inhibition of the metabolism of medicinal products that are substrates for CYP1A2, CYP2C8, CYP2C9, CYP2C19 or CYP2D6.

In vitro studies showed that Crizotinib Taj Pharma is a weak inhibitor of UGT1A1 and UGT2B7 (see section 4.5). However, in vitro studies indicated that clinical drug-drug interactions are unlikely to occur as a result of Crizotinib Taj Pharma-mediated inhibition of the metabolism of drugs that are substrates for UGT1A4, UGT1A6, or UGT1A9.

In vitro studies in human hepatocytes indicated that clinical drug-drug interactions are unlikely to occur as a result of Crizotinib Taj Pharma-mediated induction of the metabolism of medicinal products that are substrates for CYP1A2.

Elimination

Following single doses of Crizotinib Taj Pharma, the apparent plasma terminal half-life of Crizotinib Taj Pharma was 42 hours in patients.

Following the administration of a single 250mg radiolabeled Crizotinib Taj Pharma dose to healthy subjects, 63% and 22% of the administered dose was recovered in faeces and urine, respectively. Unchanged Crizotinib Taj Pharma represented approximately 53% and 2.3% of the administered dose in faeces and urine, respectively.

Coadministration with medicinal products that are substrates of transporters

Crizotinib Taj Pharma is an inhibitor of P-glycoprotein (P-gp) in vitro. Therefore, Crizotinib Taj Pharma may have the potential to increase plasma concentrations of coadministered medicinal products that are substrates of P-gp (see section 4.5).

Crizotinib Taj Pharma is an inhibitor of OCT1 and OCT2 in vitro. Therefore, Crizotinib Taj Pharma may have the potential to increase plasma concentrations of coadministered drugs that are substrates of OCT1 or OCT2 (see section 4.5).

In vitro, Crizotinib Taj Pharma did not inhibit the human hepatic uptake transport proteins organic anion transporting polypeptide (OATP)1B1 or OATP1B3 or the renal uptake transport proteins organic anion transporter (OAT)1 or OAT3 at clinically relevant concentrations. Therefore, clinical drug-drug interactions are unlikely to occur as a result of Crizotinib Taj Pharma-mediated inhibition of the hepatic or renal uptake of medicinal products that are substrates for these transporters.

Effect on other transport proteins

In vitro, Crizotinib Taj Pharma is not an inhibitor of BSEP at clinically relevant concentrations.

Pharmacokinetics in special patient groups

Hepatic Impairment

Crizotinib Taj Pharma is extensively metabolized in the liver. Patients with mild (either AST >ULN and total bilirubin ≤ULN or any AST and total bilirubin >ULN but ≤1.5×ULN), moderate (any AST and total bilirubin >1.5×ULN and ≤3×ULN), or severe (any AST and total bilirubin >3×ULN) hepatic impairment or normal (AST and total bilirubin ≤ULN) hepatic function, who were matched controls for mild or moderate hepatic impairment, were enrolled in an open-label, non-randomised clinical study (Study 1012), based on NCI classification.

Following Crizotinib Taj Pharma 250mg twice daily dosing, patients with mild hepatic impairment (N=10) showed similar systemic Crizotinib Taj Pharma exposure at steady state compared to patients with normal hepatic function (N=8), with geometric mean ratios for area under the plasma concentration-time curve as daily exposure at steady state (AUC_daily) and C_max of 91.1% and 91.2%, respectively. No starting dose adjustment is recommended for patients with mild hepatic impairment.

Following Crizotinib Taj Pharma 200mg twice daily dosing, patients with moderate hepatic impairment (N=8) showed higher systemic Crizotinib Taj Pharma exposure compared to patients with normal hepatic function (N=9) at the same dose level, with geometric mean ratios for AUC_daily and C_max of 150% and 144%, respectively. However, the systemic Crizotinib Taj Pharma exposure in patients with moderate hepatic impairment at the dose of 200mg twice daily was comparable to that observed from patients with normal hepatic function at a dose of 250mg twice daily, with geometric mean ratios for AUC_daily and C_max of 114% and 109%, respectively.

The systemic Crizotinib Taj Pharma exposure parameters AUC_daily and C_max in patients with severe hepatic impairment (N=6) receiving a Crizotinib Taj Pharma dose of 250mg once daily were approximately 64.7% and 72.6%, respectively, of those from patients with normal hepatic function receiving a dose of 250mg twice daily.

An adjustment of the dose of Crizotinib Taj Pharma is recommended when administering Crizotinib Taj Pharma to patients with moderate or severe hepatic impairment (see sections 4.2 and 4.4).

Renal Impairment

Patients with mild (60≤ CL_cr <90 mL/min) and moderate (30≤ CL_cr <60 mL/min) renal impairment were enrolled in single-arm Studies 1001 and 1005. The effect of renal function as measured by baseline CL_cr on observed Crizotinib Taj Pharma steady-state trough concentrations (C_{trough, ss}) was evaluated. In Study 1001, the adjusted geometric mean of plasma C_{trough, ss} in mild (N=35) and moderate (N=8) renal impairment patients were 5.1% and 11% higher, respectively, than those in patients with normal renal function. In Study 1005, the adjusted geometric mean C_{trough, ss} of Crizotinib Taj Pharma in mild (N=191) and moderate (N=65) renal impairment groups were 9.1% and 15% higher, respectively, than those in patients with normal renal function. In addition, the population pharmacokinetic analysis using data from Studies 1001, 1005 and 1007 indicated CL_cr did not have a clinically meaningful effect on the pharmacokinetics of Crizotinib Taj Pharma. Due to the small size of the increases in Crizotinib Taj Pharma exposure (5%-15%), no starting dose adjustment is recommended for patients with mild or moderate renal impairment.

After a single 250mg dose in subjects with severe renal impairment (CL_cr <30 mL/min) not requiring peritoneal dialysis or haemodialysis, Crizotinib Taj Pharma AUC_inf and C_max increased by 79% and 34%, respectively, compared to those with normal renal function. An adjustment of the dose of Crizotinib Taj Pharma is recommended when administering Crizotinib Taj Pharma to patients with severe renal impairment not requiring peritoneal dialysis or haemodialysis (see sections 4.2 and 4.4).

Age

Based on the population pharmacokinetic analysis of data from Studies 1001, 1005, and 1007, age has no effect on Crizotinib Taj Pharma pharmacokinetics (see sections 4.2 and 5.1).

Body Weight and Gender

Based on the population pharmacokinetic analysis of data from Studies 1001, 1005 and 1007, there was no clinically meaningful effect of body weight or gender on Crizotinib Taj Pharma pharmacokinetics.

Ethnicity

Based on the population pharmacokinetic analysis of data from Studies 1001, 1005 and 1007, the predicted area under the plasma concentration-time curve at steady-state (AUC_ss) (95% CI) was 23%-37% higher in Asian patients (N=523) than in non-Asian patients (N=691).

In studies in patients with ALK-positive advanced NSCLC (N=1669), the following adverse reactions were reported with an absolute difference of ≥10% in Asian patients (N=753) than in non-Asian patients (N=916): elevated transaminases, decreased appetite, neutropenia, and leukopenia. No adverse drug reactions were reported with an absolute difference of ≥15%.

Geriatric

Limited data are available in this subgroup of patients (see sections 4.2 and 5.1). Based on the population pharmacokinetic analysis of data in Studies 1001, 1005 and 1007, age has no effect on Crizotinib Taj Pharma pharmacokinetics.

Cardiac electrophysiology

The QT interval prolongation potential of Crizotinib Taj Pharma was assessed in patients with either ALK-positive or ROS1-positive NSCLC who received Crizotinib Taj Pharma 250mg twice daily. Serial ECGs in triplicate were collected following a single dose and at steady state to evaluate the effect of Crizotinib Taj Pharma on QT intervals. Thirty-four of 1619 patients (2.1%) with at least 1 postbaseline ECG assessment were found to have QTcF ≥500 msec, and 79 of 1585 patients (5.0%) with a baseline and at least 1 postbaseline ECG assessment had an increase from baseline QTcF ≥60 msec by automated machine-read evaluation of ECG (see section 4.4).

An ECG substudy using blinded manual ECG measurements was conducted in 52 ALK-positive NSCLC patients who received Crizotinib Taj Pharma 250mg twice daily. Eleven (21%) patients had an increase from Baseline in QTcF value ≥30 to <60 msec and 1 (2%) patient had an increase from Baseline in QTcF value of ≥60 msec. No patients had a maximum QTcF ≥480 msec. The central tendency analysis indicated that all upper limits of the 90% CI for the LS mean change from Baseline in QTcF at all Cycle 2 Day 1 time points were <20 msec. A pharmacokinetic/pharmacodynamic analysis suggested a relationship between Crizotinib Taj Pharma plasma concentration and QTc. In addition, a decrease in heart rate was found to be associated with increasing Crizotinib Taj Pharma plasma concentration (see section 4.4), with a maximum mean reduction of 17.8 beats per minute (bpm) after 8 hours on Cycle 2 Day 1.

• Preclinical safety data

In rat and dog repeat-dose toxicity studies up to 3-month duration, the primary target organ effects were related to the gastrointestinal (emesis, faecal changes, congestion), haematopoietic (bone marrow hypocellularity), cardiovascular (mixed ion channel blocker, decreased heart rate and blood pressure, increased LVEDP, QRS and PR intervals, and decreased myocardial contractility), or reproductive (testicular pachytene spermatocyte degeneration, single-cell necrosis of ovarian follicles) systems. The No Observed Adverse Effect Levels (NOAEL) for these findings were either subtherapeutic or up to 2.6-fold human clinical exposure based on AUC. Other findings included an effect on the liver (elevation of liver transaminases) and retinal function, and potential for phospholipidosis in multiple organs without correlative toxicities.

Crizotinib Taj Pharma was not mutagenic in vitro in the bacterial reverse mutation (Ames) assay. Crizotinib Taj Pharma was aneugenic in an in vitro micronucleus assay in Chinese Hamster Ovary cells and in an in vitro human lymphocyte chromosome aberration assay. Small increases of structural chromosomal aberrations at cytotoxic concentrations were seen in human lymphocytes. The NOAEL for aneugenicity was approximately 1.8-fold human clinical exposure based on AUC.

Carcinogenicity studies with Crizotinib Taj Pharma have not been performed.

No specific studies with Crizotinib Taj Pharma have been conducted in animals to evaluate the effect on fertility; however, Crizotinib Taj Pharma is considered to have the potential to impair reproductive function and fertility in humans based on findings in repeat-dose toxicity studies in the rat. Findings observed in the male reproductive tract included testicular pachytene spermatocyte degeneration in rats given ≥50mg/kg/day for 28 days (approximately 1.1-fold human clinical exposure based on AUC). Findings observed in the female reproductive tract included single-cell necrosis of ovarian follicles of a rat given 500mg/kg/day for 3 days.

Crizotinib Taj Pharma was not shown to be teratogenic in pregnant rats or rabbits. Post-implantation loss was increased at doses ≥50mg/kg/day (approximately 0.4 times the AUC at the recommended human dose) in rats, and reduced fetal body weights were considered adverse effects in the rat and rabbit at 200 and 60mg/kg/day, respectively (approximately 1.2-fold human clinical exposure based on AUC).

Decreased bone formation in growing long bones was observed in immature rats at 150mg/kg/day following once daily dosing for 28 days (approximately 3.3 times human clinical exposure based on AUC). Other toxicities of potential concern to paediatric patients have not been evaluated in juvenile animals.

The results of an in vitro phototoxicity study demonstrated that Crizotinib Taj Pharma may have phototoxic potential.
