Warnings and Precautions
5.1 Myelosuppression
(Additions and/or revisions
are underlined)
Myelosuppression,
manifested by neutropenia, anemia and thrombocytopenia, occur in patients receiving
NAVELBINE as a single agent and in combination with cisplatin. Neutropenia
is the major dose-limiting toxicity with NAVELBINE…
5.2 Hepatic Toxicity
(Additions and/or revisions
are underlined)
Drug-induced
liver injury manifest by elevated aspartate aminotransferase (AST)
and bilirubin occur in patients receiving NAVELBINE as a single agent and
in combination with cytotoxic agents. Assess hepatic function prior to
initiation of NAVELBINE and periodically during treatment. Reduce the dose of
NAVELBINE for patients who develop elevations in total bilirubin greater than
or equal to 2 times upper limit of normal.
5.3 Severe Constipation and Bowel Obstruction
(Additions and/or revisions
are underlined)
Severe
and fatal paralytic ileus, constipation, intestinal obstruction, necrosis, and perforation
occur in patients receiving NAVELBINE. 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.
5.6 Pulmonary Toxicity and Respiratory Failure
(Additions and/or revisions
are underlined)
Pulmonary
toxicity, including severe acute bronchospasm, interstitial pneumonitis, acute respiratory
distress syndrome (ARDS) occur in patients receiving NAVELBINE.
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). Interrupt NAVELBINE in patients who develop
unexplained dyspnea or have any evidence of pulmonary toxicity. Permanently
discontinue NAVELBINE for confirmed interstitial pneumonitis or ARDS.
5.7 Embryo-Fetal Toxicity
(Additions and/or revisions
are underlined)
Based
on findings from animal studies and its mechanism of action, NAVELBINE 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.
Advise
pregnant women
of the potential risk to a fetus. Advise females of reproductive
potential to use effective contraception during treatment with NAVELBINE
and for 6 months after the final dose. Advise males with female partners of reproductive
potential to use effective contraception during treatment with NAVELBINE and
for 3 months after the final dose.

Adverse Reactions
(Additions and/or revisions
are underlined)
The following clinically significant adverse reactions are described elsewhere in the labeling:
Hepatic Toxicity
Severe Constipation and Bowel Obstruction
Extravasation
and Tissue Injury
Pulmonary Toxicity and Respiratory Failure
6.1 Clinical Trials Experience
(Additions and/or revisions
are underlined)
Single Agent
The data below reflect exposure to NAVELBINE 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 patients
with previously untreated metastatic NSCLC (Study 3) who
received a median of 8 doses of NAVELBINE. 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 NAVELBINE in 222 patients
with previously treated advanced
breast cancer who received a median
of 10 doses of NAVELBINE. NAVELBINE
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 (greater than or equal to 20%) of single agent NAVELBINE
were leukopenia, neutropenia, anemia, increased aspartate aminotransferase (AST), nausea, vomiting,
constipation, asthenia, injection
site reaction and peripheral
neuropathy. The most common (greater than or equal to 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 NAVELBINE experienced at least one dose reduction due to an adverse reaction.
7
Drug Interactions
7.1 CYP3A Inhibitors
(Additions and/or revisions
are underlined)
Exercise caution in patients concurrently taking drugs known to inhibit CYP3A. Concurrent administration
of NAVELBINE with a CYP3A inhibitor
may cause an earlier onset and/or an increased
severity of adverse reactions.

Use in Specific Populations
8.1 Pregnancy
(Pregnancy
and Lactation Labeling Rule (PLLR) Conversion; Additions and/or revisions are underlined)
Risk Summary
Based on findings from animal
studies and its mechanism of action, NAVELBINE 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. 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.
8.3 Females and Males of Reproductive Potential
(Newly Added
Subsection)
Pregnancy Testing
Verify pregnancy status in females of reproductive potential prior to initiating NAVELBINE.
Contraception
Females
NAVELBINE can cause fetal
harm when administered to
pregnant women.
Advise female patients of reproductive potential to use effective contraception during treatment with NAVELBINE and for 6
months after the final dose.
Males
NAVELBINE may damage spermatozoa. Advise males with female sexual partners of
reproductive potential to use effective contraception during treatment
with NAVELBINE and for 3 months
after the final dose.
Infertility
Males
Based on animal findings,
NAVELBINE may impair fertility
in males.

Lactation
Advise women not to breastfeed during
treatment with NAVELBINE and for 9 days after the final dose.
Infertility
