Single Agent The data below reflect exposure to vinorelbine as a single agent administered at a dose of 30 mg/m 2 on a weekly basis to 365 patients enrolled in 3 controlled studies for metastatic NSCLC and advanced breast cancer. The population included 143 patients with previously untreated metastatic NSCLC (Study 3) who received a median of 8 doses of vinorelbine. The patients were aged 32 to 79 (median 61 years), 71% were male, 91% White, 48% had adenocarcinoma histology. The data also reflect exposure to vinorelbine in 222 patients with previously treated advanced breast cancer who received a median of 10 doses of vinorelbine. Vinorelbine 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 were leukopenia, neutropenia, anemia, increased aspartate aminotransferase (AST), 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, increased AST, injection site reaction and asthenia. Approximately 49% of patients with NSCLC who were treated with vinorelbine experienced at least one dose reduction due to an adverse reaction. Thirteen percent of patients discontinued vinorelbine due to adverse reactions. The most frequent adverse reactions leading to vinorelbine discontinuation were asthenia, dyspnea, nausea, constipation, anorexia, myasthenia and fever. Table 1.

7 DRUG INTERACTIONS Inhibitors of CYP3A4: May cause earlier onset and/or increased severity of adverse reactions ( 7.1 ) 7.1 CYP3A Inhibitors Exercise caution in patients concurrently taking drugs known to inhibit CYP3A. Concurrent administration of vinorelbine with a CYP3A inhibitor may cause an earlier onset and/or an increased severity of adverse reactions.

8 USE IN SPECIFIC POPULATIONS Lactation: Advise not to breastfeed ( 8.2 ) 8.1 Pregnancy Risk Summary Based on findings from animal studies and its mechanism of action [see Clinical Pharmacology ( 12.1 )] , vinorelbine can cause fetal harm when administered to a pregnant woman. Available human data are insufficient to inform the drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. 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 (see Data ) . Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies are 2 to 4% and 15 to 20%, respectively. Data Animal Data In a mouse embryo-fetal development study, administration of a single dose of vinorelbine at a dose level of 9 mg/m 2 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/m 2 (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. 8.2 Lactation Risk Summary There are no data on the presence of vinorelbine in human milk or its effects on the breastfed infant or on milk production. Because of the potential for serious adverse reactions in breastfed infants from vinorelbine, advise women not to breastfeed during treatment with vinorelbine and for 9 days after the final dose. 8.3 Females and Males of Reproductive Potential Pregnancy Testing Verify pregnancy status in females of reproductive potential prior to initiating vinorelbine [see Use in Specific Populations ( 8.1 )]. Contraception Females Vinorelbine can cause fetal harm when administered to pregnant women [see Use in Specific Populations ( 8.1 )] . Advise female patients of reproductive potential to use effective contraception during treatment with vinorelbine and for 6 months after the final dose. Males Vinorelbine may damage spermatozoa [see Nonclinical Toxicology ( 13.1 )]. Advise males with female sexual partners of reproductive potential to use effective contraception during treatment with vinorelbine and for 3 months after the final dose. Infertility Males Based on animal findings, vinorelbine may impair fertility in males [see Nonclinical Toxicology ( 13.1 )]. 8.4 Pediatric Use The safety and effectiveness of vinorelbine in pediatric patients have not been established. Results from a single-arm study of vinorelbine administered at the dose of 33.75 mg/m 2 (for 35 patients) or at the dose of 30 mg/m 2 (for 11 patients) every week for 6 weeks followed by 2 weeks of rest were 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 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 as a single agent and in combination with cisplatin in studies 1, 2 and 3, 247 patients wer …

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.
