Repeat neutrophil count in one week. If three consecutive weekly doses are held because neutrophil count is < 1,000 cells/mm 3 , discontinue Vinorelbine Injection Note: For patients who experience fever and/or sepsis while neutrophil count is < 1,500 cells/mm 3 or had 2 consecutive weekly doses held due to neutropenia, subsequent doses of Vinorelbine Injection should be: > 1,500 75% 1,000 to 1,499 37.5% < 1,000 Do not administer Vinorelbine Injection. Repeat neutrophil count in one week. Hepatic Impairment/Toxicity Reduce Vinorelbine Injection dose in patients with elevated serum total bilirubin concentration according to the following schema [see Warnings and Precautions ( 5.2 ) and Use in Specific Populations ( 8.6 )] : Serum Total Bilirubin Concentration (mg/dl) Percentage of Starting Dose of Vinorelbine Injection ≤ 2.0 100% 2.1 to 3.0 50% > 3.0 25% Concurrent Myelosuppression and Hepatic Impairment/Toxicity In patients with both myelosuppression and hepatic impairment/toxicity, administer the lower of the doses based on the corresponding starting dose of Vinorelbine Injection determined from the above schemas. Neurologic Toxicity Discontinue Vinorelbine Injection for Common Terminology Criteria for Adverse Events (CTCAE) Grade 2 or higher peripheral neuropathy or autonomic neuropathy causing constipation [see Warnings and Precautions ( 5.5 )]. 2.3 Preparation and Administration Preparation Dilute Vinorelbine Injection in an intravenous bag to a concentration between 0.5 mg/mL and 2 mg/mL. Use one of the following recommended solutions for dilution: 5% Dextrose Injection, USP 0.9% Sodium Chloride Injection, USP 0.45% Sodium Chloride Injection, USP 5% Dextrose and 0.45% Sodium Chloride Injection, USP Ringer's Injection, USP Lactated Ringer's Injection, USP Stability and Storage Conditions of Diluted Solutions Diluted Vinorelbine Injection may be used for up to 24 hours under normal room light when stored in polyvinyl chloride bags at 5° to 30°C (41° to 86°F). Administration Administer diluted Vinorelbine Injection over 6 to 10 minutes into the side port of a free-flowing intravenous line followed by flushing with at least 75 to 125 mL of one of the solutions. Vinorelbine Injection must only be administered intravenously. It is extremely important that the intravenous needle or catheter be properly positioned before any Vinorelbine Injection is injected. Parenteral drug products should be visually inspected for particulate matter and discoloration prior to administration whenever solution and container permit. If particulate matter is seen, Vinorelbine Injection should not be administered. Management of Suspected Extravasation If Vinorelbine Injection leakage into surrounding tissue occurs or is suspected, immediately stop administration of Vinorelbine Injection and initiate appropriate management measures in accordance with institutional policies [see Warnings and Precautions ( 5.4 )]. 2.4 Procedures for Proper Handling and Disposal Vinorelbine Injection is a cytotoxic drug. Follow applicable special handling and disposal procedures 1 . Exercise caution in handling and preparing the solution of Vinorelbine Injection. The use of gloves is recommended. If the solution of Vinorelbine Injection contacts the skin or mucosa, immediately wash the skin or mucosa thoroughly with soap and water. Avoid contamination of the eye with Vinorelbine Injection. If exposure occurs, flush the eyes with water immediately and thoroughly. Discard unused portion.

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.

Neutropenia is the major dose-limiting toxicity. Neurotoxicity: Neurotoxicity was most commonly manifested as constipation, paresthesia, hyperesthesia and hyporeflexia. Grade 3 and 4 neuropathy was observed in 1% of the patients receiving single agent vinorelbine. 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 ˂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 treated patients reported in a randomized trial comparing the combination of vinorelbine 25 mg/m 2 administered every week of each 28-day cycle and cisplatin 100 mg/m 2 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 plus cisplatin received a median of 3 cycles of treatment and those randomized to cisplatin alone received a median of 2 cycles of treatment. The incidence of Grade 3 and 4 neutropenia was significantly higher in the vinorelbine plus cisplatin arm (82%) compared to the cisplatin alone arm (5%). 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. Four patients in the vinorelbine 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 and 3 from febrile neutropenia.

A total of 604 patients received either vinorelbine 30 mg/m 2 every week plus cisplatin 120 mg/m 2 on Day 1 and Day 29, then every 6 weeks thereafter (N=207), vindesine 3 mg/m 2 for 6 weeks, then every other week thereafter plus cisplatin 120 mg/m 2 on Days 1 and Day 29, then every 6 weeks thereafter (N=193) or vinorelbine 30mg/m 2 every week (N=204). Patients randomized to vinorelbine plus cisplatin received a median of 15 weeks of treatment, vindesine plus cisplatin 12 weeks and vinorelbine received 13 weeks. Grade 3 and 4 neutropenia was significantly greater in the vinorelbine plus cisplatin arm (78%) compared to vindesine plus cisplatin (48%) and vinorelbine as a single agent (53%). Neurotoxicity, including peripheral neuropathy and constipation, was reported in 44% (Grade 3-4, 7%) of the patients receiving vinorelbine plus cisplatin, 58% (Grade 3-4, 17%) of the patients receiving vindesine and cisplatin and 44% (Grade 3-4, 8.5%) of the patients receiving vinorelbine as a single agent. Study discontinuation due to an adverse reaction was required in 27, 22 and 10% of the patients randomized to vinorelbine plus cisplatin, vindesine plus cisplatin and cisplatin alone arms, respectively.

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.
