Vinorelbine (Page 3 of 5)

6.2 Postmarketing Experience

The following adverse reactions have been identified during postapproval use of vinorelbine. 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: 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), palmar-plantar erythrodysesthesia syndrome

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 CYP3A. Concurrent administration of vinorelbine with a CYP3A inhibitor may cause an earlier onset and/or an increased severity of adverse reactions.


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.


Animal Data

In a mouse embryo-fetal 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.

8.2 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)].



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.


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.



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/m2 (for 35 patients) or at the dose of 30 mg/m2 (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 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 has not been evaluated, but the liver plays an important role in the metabolism of vinorelbine. Elevated AST occurs in >60% of the patients receiving vinorelbine as a single agent (6% Grade 3-4). Therefore, exercise caution in patients with hepatic impairment. Reduce the dose of vinorelbine for patients with elevated serum total bilirubin concentrations [see Dosage and Administration (2.2) and Warnings and Precautions (5.2)].


There is no known antidote for overdoses of vinorelbine. Overdoses involving quantities up to 10 times the recommended dose (30 mg/m2) have been reported. The adverse reactions described were consistent with those listed in the ADVERSE REACTIONS section, including paralytic ileus, stomatitis and esophagitis. Bone marrow aplasia, sepsis and paresis have also been reported. Fatalities have occurred following overdose of vinorelbine. If overdosage occurs, general supportive measures together with appropriate blood transfusions, growth factors and antibiotics should be instituted as deemed necessary by the physician.
