5.1 Myelosuppression

Myelosuppression manifested by neutropenia, anemia and thrombocytopenia occur with Vinorelbine Injection as a single agent and in combination with cisplatin [see Adverse Reactions (6.1 and 6.2)]. Neutropenia is the major dose-limiting toxicity with Vinorelbine Injection.  Grade 3-4 neutropenia occurred in 53% of patients treated with Vinorelbine Injection, at 30 mg/m2 per week. Dose adjustment due to myelosuppression occurred in 51% of patients (Study 2). In clinical trials with Vinorelbine Injection administered at 30 mg/m2 per week, neutropenia resulted in hospitalizations for pyrexia and/or sepsis in 8% of patients. Death due to sepsis occurred in 1% of patients. Neutropenia nadirs occur between 7 and 10 days after dosing with neutropenia count recovery usually occurring within the following 7 to 14 days.

Monitor complete blood counts prior to each dose of Vinorelbine Injection. Do not administer Vinorelbine Injection to patients with neutrophil counts <1,000 cells/mm3.  Adjustments in the dosage of Vinorelbine Injection, should be based on neutrophil counts obtained on the day of treatment [see Dosage and Administration (2.2)].

5.2 Hepatic Toxicity

Drug-induced liver injury manifest by elevations of aspartate aminotransferase and bilirubin can occur in patients receiving Vinorelbine Injection, alone or in combination with cytotoxic agents. Assess hepatic function prior to initiation of Vinorelbine Injection, and periodically during treatment.  Reduce the dose of Vinorelbine Injection, for patients who develop elevations in total bilirubin > 2 times upper limit of normal [see Dosage and Administration (2.2) and Use in Specific Populations (8.5)].

5.3 Severe Constipation and Bowel Obstruction

Severe and fatal paralytic ileus, constipation, intestinal obstruction, necrosis, and perforation occur with Vinorelbine Injection, administration. Institute a prophylactic bowel regimen to mitigate potential constipation, bowel obstruction and/or paralytic ileus, considering adequate dietary fiber intake, hydration, and routine use of stool softeners.

5.4 Extravasation and Tissue Injury

Extravasation of Vinorelbine Injection, can result in severe irritation, local tissue necrosis and/or thrombophlebitis. If signs or symptoms of extravasation occur, immediately stop administration of Vinorelbine Injection, and institute recommended management procedures. [see Dosage and Administration (2.2) and Adverse Reactions (6.1)]

5.5 Neurologic Toxicity

Sensory and motor neuropathies, including severe neuropathies, occur in patients receiving Vinorelbine Injection. Monitor patients for new or worsening signs and symptoms of neuropathy such as paresthesia, hyperesthesia, hyporeflexia and muscle weakness while receiving Vinorelbine Injection. Discontinue Vinorelbine Injection for NCI CTCAE Grade 2 or greater neuropathy [see Dosage and Administration (2.2) and Adverse Reactions (6.1)]

5.6 Pulmonary Toxicity and Respiratory Failure

Pulmonary toxicity, including severe acute bronchospasm, interstitial pneumonitis, acute respiratory distress syndrome (ARDS) occurs with use of Vinorelbine Injection. Interstitial pneumonitis and ARDS included fatalities.  The mean time to onset of interstitial pneumonitis and ARDS after vinorelbine administration was one week (range 3 to 8 days) [see  Adverse Reactions (6.1)].

Interrupt Vinorelbine Injection in patients who develop unexplained dyspnea, or have any evidence of pulmonary toxicity. Permanently discontinue Vinorelbine Injection for confirmed interstitial pneumonitis or ARDS.

5.7 Embryo-Fetal Toxicity

Vinorelbine Injection can cause fetal harm when administered to a pregnant woman. In animal reproduction studies in mice and rabbits, embryo and fetal toxicity were observed with administration of vinorelbine at doses approximately 0.33 and 0.18 times the human therapeutic dose, respectively.  If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to a fetus. Advise females of reproductive potential to use highly effective contraception during therapy with Vinorelbine Injection [see Use in Specific Populations (8.1, 8.7)].

6.1 Clinical Trials Experience

Because clinical trials are conducted under varying designs and in different patient populations, the adverse reaction rates reported in one clinical trial may not be easily compared to those rates reported in another clinical trial, and may not reflect the rates actually observed in clinical practice.

Single Agent

The data below reflect exposure to Vinorelbine Injection as a single agent administered at a dose of 30 mg/m2 on a weekly basis to 365 patients enrolled in 3 controlled studies for metastatic NSCLC and advanced breast cancer. The population included 143 previously untreated metastatic NSCLC patients (Study 3) who received a median of 8 doses of Vinorelbine Injection. The patients were aged 32 to 79 (median 61 years), 71% were male, 91% Caucasian, 48% had adenocarcinoma histology.  The data also reflect exposure to Vinorelbine Injection in 222 patients with previously treated advanced breast cancer who received a median of 10 doses of Vinorelbine Injection. Vinorelbine Injection is not indicated for the treatment of breast cancer.

Selected adverse reactions reported in these studies are provided in Tables 1 and 2.  The most common adverse reactions (≥ 20%) of single agent Vinorelbine Injection were leukopenia, neutropenia, anemia, Aspartate aminotransferase (AST) elevation, nausea, vomiting, constipation, asthenia, injection site reaction, and peripheral neuropathy.  The most common (≥ 5%) Grade 3 or 4 adverse reactions were neutropenia, leukopenia, anemia, increased total bilirubin, AST elevation, injection site reaction and asthenia. Approximately 49% of NSCLC patients treated with Vinorelbine Injection experienced at least one dose reduction due to an adverse reaction. Thirteen percent of patients discontinued Vinorelbine Injection due to adverse reactions. The most frequent adverse reactions leading to Vinorelbine Injection discontinuation were asthenia, dyspnea, nausea, constipation, anorexia, myasthenia and fever.   

Myelosuppression: In clinical trials, Grade 3-4 neutropenia, anemia, and thrombocytopenia occurred in 69%, 9% and 1%, respectively of patients receiving single-agent Vinorelbine Injection. Neutropenia is the major dose-limiting toxicity.

Neurotoxicity: Neurotoxicity was most commonly manifested as constipation, paresthesia, hypersthesia, and hyporeflexia.  Grade 3 and 4 neuropathy was observed in 1% of the patients receiving single-agent Vinorelbine Injection.

Injection site reactions:  Injection site reactions, including erythema, pain at injection site, and vein discoloration, occurred in approximately one third of patients; 5% were severe. Phlebitis (chemical phlebitis) along the vein proximal to the site of injection was reported in 10% of patients.

Cardiovascular toxicity: Chest pain occurred in 5% of patients; myocardial infarction occurred in less than 0.1% of patients.

Pulmonary Toxicity and Respiratory Failure: Dyspnea (shortness of breath) was reported in 3% of patients; it was severe in 2%. Interstitial pulmonary changes were documented.

Other: Hemorrhagic cystitis and the syndrome of inappropriate ADH secretion were each reported in <1% of patients.

In Combination with Cisplatin

Table 3 presents the incidence of selected adverse reactions, occurring in ≥ 10% of Vinorelbine Injection treated patients reported in a randomized trial comparing the combination of Vinorelbine Injection 25 mg/m2 administered every week of each 28-day cycle and cisplatin 100 mg/m2 administered on day 1 of each 28-day cycle versus cisplatin alone at the same dose and schedule in patients with previously untreated NSCLC (Study 1).

Patients randomized to Vinorelbine Injection plus cisplatin received a median of 3 cycles of treatment and those randomized to cisplatin alone received a median of 2 cycles of treatment.  Thirty-Five percent of the eligible patients in the combination arm required treatment discontinuation due to an adverse reaction compared to 19% in the cisplatin alone arm. The incidence of Grade 3 and 4 neutropenia was significantly higher in the Vinorelbine Injection plus cisplatin arm (82%) compared to the cisplatin alone arm (5%).  Four patients in the Vinorelbine Injection plus cisplatin arm died of neutropenic sepsis.  Seven additional deaths were reported in the combination arm: 2 from cardiac ischemia, 1 cerebrovascular accident, 1 multisystem failure due to an overdose of Vinorelbine Injection, and 3 from febrile neutropenia.

Table 4 presents the incidence of selected adverse reactions, occurring in ≥ 10% of Vinorelbine Injection treated patients reported in a randomized trial of Vinorelbine Injection plus cisplatin, vindesine plus cisplatin and Vinorelbine Injection alone in patients with stage III or IV NSCLC who had not received prior chemotherapy.  A total of 604 patients received either Vinorelbine Injection 30 mg/m2 every week plus cisplatin 120 mg/m2 on Day 1 and Day 29, then every 6 weeks thereafter (N=207), vindesine 3 mg/m2 for 6 weeks, then every other week thereafter plus cisplatin 120 mg/m2 on Days 1 and Day 29, then every 6 weeks thereafter (N=193) or Vinorelbine Injection 30 mg/m2 every week (N=204).

Patients randomized to Vinorelbine Injection plus cisplatin received a median of 15 weeks of treatment, vindesine plus cisplatin 12 weeks and Vinorelbine Injection received 13 weeks. Study discontinuation due to an adverse reaction was required in 27, 22 and 10% of the patients randomized to Vinorelbine Injection plus cisplatin, vindesine plus cisplatin and cisplatin alone arms, respectively. Grade 3 and 4 neutropenia was significantly greater in the Vinorelbine Injection plus cisplatin arm (78%) compared to vindesine plus cisplatin (48%) and Vinorelbine Injection alone (53%). Neurotoxicity, including peripheral neuropathy and constipation was reported in 44% (Grades 3 4, 7%) of the patients receiving Vinorelbine Injection plus cisplatin, 58% (Grades 3-4, 17%) of the patients receiving vindesine and cisplatin and 44% (Grades 3-4, 8.5%) of the patients receiving Vinorelbine Injection alone.

6.2 Postmarketing Experience

The following adverse reactions have been identified during post-approval use of Vinorelbine Injection. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Infections and infestations: pneumonia

Immune system disorders: anaphylactic reaction, pruritus, urticaria, angioedema

Nervous system disorders: loss of deep tendon reflexes, muscular weakness, gait disturbance, headache

Ear and labyrinth disorders: vestibular disorder, hearing impaired

Cardiac disorders: tachycardia

Respiratory disorders: pulmonary edema

Vascular disorders: pulmonary embolism, deep vein thrombosis, hypertension, hypotension, flushing, vasodilatation

Gastrointestinal disorders: mucosal inflammation, dysphagia, pancreatitis

Skin disorders: generalized cutaneous reactions (rash)

Musculoskeletal and connective tissue disorders: jaw pain, myalgia, arthralgia

General disorders and administration site conditions: injection site rash, urticaria, blistering, sloughing of skin

Injury, poisoning  and  procedural  complications:  radiation  recall  phenomenon,  dermatitis, esophagitis

Laboratory abnormalities: electrolyte imbalance including hyponatremia

Other: tumor pain, back pain, abdominal pain

7.1 CYP3A Inhibitors

Exercise caution in patients concurrently taking drugs known to inhibit drug metabolism by hepatic cytochrome P450 isoenzymes in the CYP3A subfamily.  Concurrent administration of Vinorelbine Injection with an inhibitor of this metabolic pathway may cause an earlier onset and/or an increased severity of adverse reactions.

8.1 Pregnancy

Pregnancy Category D

Risk Summary

Vinorelbine Injection can cause fetal harm when administered to a pregnant woman. In animal reproduction studies in mice and rabbits, embryo and fetal toxicity were observed with administration of vinorelbine at doses approximately 0.33 and 0.18 times the human therapeutic dose, respectively.  If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to a fetus.

Animal Data

In a mouse embryofetal development study, administration of a single dose of vinorelbine at a dose level of 9 mg/m2 or greater (approximately 0.33 times the recommended human dose based on body surface area) was embryotoxic and fetotoxic. Vinorelbine was embryotoxic and fetotoxic to pregnant rabbits when administered every 6 days during the period of organogenesis at doses of 5.5 mg/m2 (approximately 0.18 times the recommended human dose based on body surface area) or greater.  At doses that did not cause maternal toxicity in either species, vinorelbine administration resulted in reduced fetal weight and delayed ossification.

8.3 Nursing Mothers

It is not known whether this drug is present in human milk. Because many drugs are present in human milk and because of the potential for serious adverse reactions in nursing infants from vinorelbine, a decision should be made whether to discontinue nursing or discontinue the drug taking into account the importance of the drug to the mother.

8.4 Pediatric Use

The safety and effectiveness of Vinorelbine Injection in pediatric patients have not been established. Results from a single-arm study of Vinorelbine Injection administered at the dose of 33.75 mg/m2 (for 35 patients) or at the dose of 30mg/m2 (for 11 patients) every week during 6 weeks followed by 2 weeks of rest was evaluated (courses of 8 weeks). Forty-six patients age 1 to 25 (median 11 years) with recurrent solid malignant tumors, including rhabdomyosarcoma or undifferentiated sarcoma (N=21 patients), neuroblastoma (N= 4 patients), and central nervous system (CNS) tumors (N=21 patients) were enrolled.  The most significant grade 3 or 4 hematological adverse reactions were neutropenia (70%) and anemia (33%). The most significant grade 3 or 4 non  hematological toxicity adverse reactions were motor (15%) or cranial (13%) neuropathy, hypoxia (13%) and dyspnea (11%). Objective tumor response was observed in 2 out of 21 patients with rhabdomyosarcoma or undifferentiated sarcoma.  No objective tumor response was observed in patients with CNS tumors (N=21) or neuroblastoma (N=4).

8.5 Geriatric Use

Of the 769 number of patients who received Vinorelbine Injection alone and Vinorelbine Injection in combination with Cisplatin in studies  1, 2 and 3, 247 patients were 65 years of age or older. No overall differences in safety, efficacy and pharmacokinetic parameters were observed between these patients and younger patients. [see Clinical Pharmacology (12.3)].

8.6 Hepatic Impairment

The influence of hepatic impairment on the pharmacokinetics of Vinorelbine Injection has not been evaluated, but the liver plays an important role in the metabolism of Vinorelbine Injection. Elevations of aspartate aminotransferase occur in > 60% of the patients receiving Vinorelbine Injection alone (6% Grade 3-4). Therefore, exercise caution in patients with hepatic impairment. Reduce the dose of Vinorelbine Injection for patients with bilirubin elevation [see Dosage and Administration (2.2) and Warnings and Precautions (5.2)].

8.7 Females and Males of Reproductive Potential

Contraception

Females

Vinorelbine Injection can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)]. Advise female patients of reproductive potential to use highly effective contraception during therapy with Vinorelbine Injection.

Males

Vinorelbine Injection may damage spermatozoa [see Nonclinical Toxicology (13.1)].  Males with female sexual partners of reproductive potential should use highly effective contraception during and for 3 months after therapy with Vinorelbine Injection.

Fertility

Males

Based on animal findings, Vinorelbine Injection may cause decreased fertility in males [see Nonclinical Toxicology (13.1)]

12.1 Mechanism of Action

Vinorelbine is a vinca alkaloid that interferes with microtubule assembly. The antitumor activity of vinorelbine is thought to be due primarily to inhibition of mitosis at metaphase through its interaction with tubulin.  Vinorelbine may also interfere with: 1) amino acid, cyclic AMP, and glutathione metabolism, 2) calmodulin-dependent Ca++-transport ATPase activity, 3) cellular respiration, and 4) nucleic acid and lipid biosynthesis. Vinorelbine inhibited mitotic microtubule formation in intact mouse embryo tectal plates at a concentration of 2 µM inducing a blockade of cells at metaphase, but produced depolymerization of axonal microtubules at a concentration 40 µM, suggesting a modest selectivity of vinorelbine for mitotic microtubules.

12.3 Pharmacokinetics

The pharmacokinetics of vinorelbine were studied in 49 patients who received doses of 30 mg/m2 administered as 15- to 20-minute constant-rate infusions. Vinorelbine concentrations in plasma decay in a triphasic manner. The terminal phase half-life averages 27.7 to 43.6 hours and the mean plasma clearance ranges from 0.97 to 1.26 L/hr/kg.

Distribution

Steady-state volume of distribution (VSS) values range from 25.4 to 40.1 L/kg. Vinorelbine demonstrated high binding to human platelets and lymphocytes. The free fraction was approximately 0.11 in human plasma over a concentration range of 234 to 1169 ng/mL. The binding to plasma constituents in cancer patients ranged from 79.6% to 91.2%. Vinorelbine binding was not altered in the presence of cisplatin, 5-fluorouracil, or doxorubicin.

Metabolism

Vinorelbine undergoes substantial hepatic elimination in humans, with large amounts recovered in feces. Two metabolites of vinorelbine have been identified in human blood, plasma, and urine; vinorelbine N-oxide and deacetylvinorelbine. Deacetylvinorelbine has been demonstrated to be the primary metabolite of vinorelbine in humans, and has been shown to possess antitumor activity similar to vinorelbine. Therapeutic doses of vinorelbine (30 mg/m2) yield very small, if any, quantifiable levels of either metabolite in blood or urine. The metabolism of vinorelbine is mediated by hepatic cytochrome P450 isoenzymes in the CYP3A subfamily.

Excretion

After intravenous administration of radioactive vinorelbine, approximately 18% and 46% of administered radioactivity was recovered in urine and feces, respectively. In a different study, 10.9% ± 0.7% of a 30-mg/m2 intravenous dose was excreted as parent drug in urine.

Specific Populations

Elderly: Age has no effect on the pharmacokinetics (CL, VSS and t1/2) of vinorelbine.

Drug Interactions

The pharmacokinetics of vinorelbine are not influenced by the concurrent administration of cisplatin.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

The carcinogenic potential of Vinorelbine Injection has not been studied. Vinorelbine has been shown to affect chromosome number and possibly structure in vivo (polyploidy in bone marrow cells from Chinese hamsters and a positive micronucleus test in mice). It was not mutagenic in the Ames test and gave inconclusive results in the mouse lymphoma TK Locus assay.

Vinorelbine did not affect fertility to a statistically significant extent when administered to rats on either a once-weekly (9 mg/m2, approximately one third the human dose) or alternate-day schedule (4.2 mg/m2, approximately 0.14 times the human recommended dose) prior to and during mating.  In male rats, administration of vinorelbine twice weekly for 13 or 26 weeks at dose levels of 2.1 and 7.2 mg/m2 (approximately 0.07 and 0.24 times the recommended human dose), respectively, resulted in decreased spermatogenesis and prostate/seminal vesicle secretion.

14.1 Combination Use with Cisplatin

The safety and efficacy of Vinorelbine Injection in combination with cisplatin was evaluated in two randomized, multicenter trials.

Cisplatin 100 mg/m2                                

Study 1 was a randomized, multicenter, open-label trial of Vinorelbine Injection plus cisplatin and cisplatin alone for the treatment of stage IV or stage IIIb NSCLC patients with malignant pleural effusion or multiple lesions in more than one lobe of the ipsilateral lung who had not received prior chemotherapy. A total of 432 patients were randomized 1:1 to receive either Vinorelbine Injection 25 mg/m2 on Day 1 then every week of each 28-day cycle with cisplatin 100 mg/m2 administered on Day 1 of each 28-day cycle (N=214) or cisplatin 100 mg/m2 on Day 1 of each 28-day cycle (N=218).

Patient demographics and disease characteristics were similar between arms. Of the overall study population, the median age was 64 (range 33-84), 66% were male, 80% were Caucasian, 92% had stage IV disease and 8% stage IIIB, 53% had adenocarcinoma, 21% squamous cell, 14% large cell histology. The major efficacy outcome measure was overall survival. The efficacy results are presented in Table 7 and Figure 1.

Figure 1: Overall Survival Vinorelbine Injection/Cisplatin versus Single-Agent Cisplatin

Cisplatin 120 mg/m2

Study 2 was a randomized, 3-arm, open-label, multicenter trial of Vinorelbine Injection plus cisplatin, vindesine plus cisplatin and Vinorelbine Injection alone for the treatment of patients with stage III or IV NSCLC who had not received prior chemotherapy.  The study was conducted in Europe.  A total of 612 patients were randomized 1:1:1 to receive Vinorelbine Injection 30 mg/m2 every week of a 6  week cycle plus cisplatin 120 mg/m2 on Day 1 and Day 29, then every 6 weeks thereafter (N=206); and vindesine 3 mg/m2 for 6 weeks, then every other week thereafter plus cisplatin 120 mg/m2 on Days 1 and Day 29, then every 6 weeks thereafter (N=200) or Vinorelbine Injection 30mg/m2 every week of a 6-week cycle (N=206). The main efficacy outcome measure was to compare overall survival between Vinorelbine Injection plus cisplatin and vindesine plus cisplatin.  The other efficacy outcome measure was to compare overall survival in the better of the two combination regimens to that of Vinorelbine Injection alone.

Patient demographics were in general similar between arms: the median age of the overall population was 60 years (range 30 to 75), 90% were male, 78% had WHO performance status of 0 or 1. Tumor characteristics were in general similar with the exception of histologic subtype of NSCLC. Adenocarcinoma was the histologic subtype in 32% of patients in the Vinorelbine Injection plus cisplatin arm, 40% of patients in vindesine plus cisplatin arm and 28% of patients on the Vinorelbine Injection alone arm. Ten percent of the patients had stage IIIA disease, 28% stage IIIB and 50% stage IV. Twelve percent of the patients had received prior surgery or radiotherapy. The efficacy results of Study 2 are presented in Table 8.

14.2 Single Agent

The safety and efficacy of Vinorelbine Injection as a single agent was evaluated in one randomized multi-center trial.

Study 3 was a randomized, open-label clinical trial of Vinorelbine Injection or 5-Fluorouracil (5-FU) plus leucovorin (LV) in patients with Stage IV NSCLC who had not received prior chemotherapy A total of 211 patients were randomized 2:1 to receive Vinorelbine Injection 30 mg/m2 weekly of a 8-week cycle (N=143) or 5-FU 425 mg/m2 bolus intravenously plus LV 20 mg/m2 bolus intravenously daily for 5 days of a 4-weeks cycle (N=68).

Patient demographics and disease characteristics were in general similar between arms.  In the overall population, the median age was 61 years (range 32 - 83), 74% were male, 88% were Caucasian, 46% had adenocarcinoma histology. Fifty percent of the patients had Karnofsky performance status ≥ 90 in the Vinorelbine Injection arm compared to 38% in the 5-FU and LV arm.

The primary efficacy outcome of the study was overall survival. The median survival time was 30 weeks versus 22 weeks for patients receiving Vinorelbine Injection versus 5-FU/LV, respectively (P=0.06). Partial objective responses were observed in 11.1% (95% CI=6.2%, 17.9%) and 3.5% (95% CI=0.4%, 11.9%) of patients who received Vinorelbine Injection and 5-FU/LV, respectively.
