5.1 Hypersensitivity
Reactions
Additions and/or
revisions underlined:
Serious and fatal
hypersensitivity reactions, including anaphylaxis, can occur with
oxaliplatin within minutes of administration and during any cycle. Grade 3-4
hypersensitivity reactions, including anaphylaxis, occurred in 2% to 3% of
patients with colon cancer who received oxaliplatin. Hypersensitivity
reactions, including rash, urticaria, erythema, pruritus, and rarely,
bronchospasm and hypotension, were similar in nature and severity to those
reported with other platinum-based drugs.
Oxaliplatin is
contraindicated in patients with hypersensitivity reactions to platinum-based
drugs [see Contraindications (4)]. Immediately and permanently
discontinue oxaliplatin for hypersensitivity reactions and administer
appropriate treatment for management of hypersensitivity reactions.
5.2 Peripheral Sensory Neuropathy
Subsection
title revised
Extensive
changes; please refer to label for complete information
5.3 Severe Myelosuppression
Subsection
title revised
Grade
3 or 4 neutropenia occurred in 41% to 44% of patients with colorectal cancer
who received oxaliplatin with fluorouracil/leucovorin. Sepsis, neutropenic
sepsis and septic shock, including fatal outcomes, occurred in patients who
received oxaliplatin [see Adverse
Reactions (6.1, 6.2)].
Grade
3 or 4 thrombocytopenia occurred in 2% to 5% of patients with colorectal cancer
who received oxaliplatin with fluorouracil/leucovorin.
Monitor
complete blood cell count at baseline, before each subsequent cycle and as
clinically indicated. Delay Oxaliplatin Injection until neutrophils are
greater than or equal to 1.5 × 109/L and platelets are greater
than or equal to 75 × 109/L. Withhold Oxaliplatin Injection for
sepsis or septic shock. Dose reduce Oxaliplatin Injection after recovery from
grade 4 neutropenia, febrile neutropenia or grade 3-4 thrombocytopenia as
recommended [see Dosage and
Administration (2.2)].
5.4
Posterior Reversible Encephalopathy Syndrome
Newly
added subsection:
PRES
occurred in less than 0.1% of patients across clinical trials [see Adverse Reactions (6.1)]. Signs and
symptoms of PRES can include headache, altered mental functioning, seizures,
abnormal vision from blurriness to blindness, associated or not with
hypertension. Confirm the diagnosis of PRES with magnetic resonance imaging.
Permanently discontinue Oxaliplatin Injection in patients who develop PRES.
5.5 Pulmonary Toxicity
Additions
and/or revisions underlined:
Oxaliplatin
has been associated with pulmonary fibrosis (less than 1% of patients), which
may be fatal [see Adverse Reactions
(6.1)].
In
the adjuvant treatment trial, the combined incidence of cough and
dyspnea was 7.4% (any grade), including less than 1% (grade 3) in the
oxaliplatin arm. One patient died from eosinophilic pneumonia in the
oxaliplatin arm.
In
the previously untreated advanced colorectal cancer trial, the combined
incidence of cough, dyspnea, and hypoxia was 43% (any grade), including 7%
(grade 3-4) in the oxaliplatin with fluorouracil/leucovorin arm.
In
case of unexplained respiratory symptoms, such as non-productive cough,
dyspnea, crackles, or radiological pulmonary infiltrates, withhold
Oxaliplatin Injection until further pulmonary investigation excludes
interstitial lung disease or pulmonary fibrosis. Permanently discontinue
Oxaliplatin Injection for confirmed interstitial lung disease or pulmonary
fibrosis.
5.6 Hepatotoxicity
Additions
and/or revisions underlined:
In
the adjuvant treatment trial, increased transaminases (57% vs 34%) and
alkaline phosphatase (42% vs 20%) occurred more commonly in the oxaliplatin arm
than in the fluorouracil/leucovorin arm [see Adverse Reactions (6.1)]. The incidence of increased
bilirubin was similar on both arms. Changes noted on liver biopsies include:
peliosis, nodular regenerative hyperplasia or sinusoidal alterations,
perisinusoidal fibrosis, and veno-occlusive lesions.
Consider
evaluating patients who develop abnormal liver tests or portal hypertension,
which cannot be explained by liver metastases, for hepatic vascular disorders.
Monitor liver function tests at baseline, before each subsequent cycle, and as
clinically indicated.
5.7 QT Interval Prolongation and Ventricular Arrhythmias
Subsection
title revision
Additions
and/or revisions underlined:
QT prolongation and ventricular arrhythmias,
including fatal torsade de pointes, have been reported with oxaliplatin [see Adverse Reactions (6.2)].
Avoid Oxaliplatin Injection in patients with
congenital long QT syndrome. Monitor electrocardiograms (ECG) in patients with congestive heart failure, bradyarrhythmias, and
electrolyte abnormalities and in patients taking drugs known to prolong the
QT interval, including Class Ia and III antiarrhythmics [see Drug Interactions (7.1)]. Monitor and correct
electrolyte abnormalities prior to initiating Oxaliplatin Injection and
periodically during treatment.
5.8 Rhabdomyolysis
Additions
and/or revisions underlined:
Rhabdomyolysis,
including fatal cases, has been reported with oxaliplatin [see Adverse Reactions (6.2)]. Permanently discontinue
Oxaliplatin Injection for any signs or symptoms of rhabdomyolysis.
5.9 Hemorrhage
Newly
added subsection:
The
incidence of hemorrhage in clinical trials was higher on the oxaliplatin
combination arm compared to the fluorouracil/leucovorin arm. These reactions
included gastrointestinal bleeding, hematuria, and epistaxis. In the adjuvant
treatment trial, 2 patients died from intracerebral hemorrhage [see Adverse Reactions (6.1)].
Prolonged
prothrombin time and INR occasionally associated with hemorrhage have been
reported in patients who received oxaliplatin with fluorouracil/leucovorin
while on anticoagulants [see Adverse
Reactions (6.2)]. Increase frequency of monitoring in patients who are
receiving Oxaliplatin Injection with fluorouracil/leucovorin and oral
anticoagulants [see Drug Interactions
(7.3)].
Thrombocytopenia
and immune-mediated thrombocytopenia have been observed with oxaliplatin. Rapid
onset of thrombocytopenia and greater risk of bleeding have been observed in
immune-mediated thrombocytopenia. In this case, consider discontinuing
Oxaliplatin Injection.
8.4 Pediatric Use
Extensive changes; please refer to label for
complete information
8.5 Geriatric Use
Additions
and/or revisions underlined:
In
the adjuvant treatment trial [see
Clinical Studies (14.1)], 400 patients who received oxaliplatin with
fluorouracil/leucovorin were greater than or equal to 65 years. The effect of
oxaliplatin in patients greater than or equal to 65 years was not conclusive. Patients
greater than or equal to 65 years receiving oxaliplatin experienced more diarrhea
and grade 3-4 neutropenia (45% vs 39%) compared to patients less
than 65 years.
In
the previously untreated advanced colorectal cancer trial [see Clinical Studies (14.2)], 99 patients who received oxaliplatin
with fluorouracil and leucovorin were greater than or equal to 65 years. The
same efficacy improvements in response rate, time to tumor progression, and
overall survival were observed in the greater than or equal to 65 years patients
as in the overall study population. Adverse reactions were similar in patients
less than 65 and greater than or equal to 65 years, but older patients may
have been more susceptible to diarrhea, dehydration, hypokalemia,
leukopenia, fatigue, and syncope.
In
the previously treated advanced colorectal cancer trial [see Clinical Studies (14.3)], 55 patients who received oxaliplatin
with fluorouracil and leucovorin were greater than or equal to 65 years. No
overall differences in effectiveness were observed between these patients and
younger adults. Adverse reactions were similar in patients less than 65 and
greater than or equal to 65 years, but older patients may have been more
susceptible to diarrhea, dehydration, hypokalemia, and fatigue.
No
significant effect of age on the clearance of ultrafiltrable platinum has been
observed [see Clinical Pharmacology
(12.3)].
8.6
Patients with Renal Impairment
Subsection
title revised
Additions
and/or revisions underlined:
The
AUC of unbound platinum in plasma ultrafiltrate was increased in patients with renal
impairment [see Clinical Pharmacology
(12.3)]. No dose reduction is recommended for patients with mild
(creatinine clearance 50 to 79 mL/min) or moderate (creatinine clearance
30 to 49 mL/min) renal impairment, calculated by Cockcroft-Gault equation. Reduce
the dose of Oxaliplatin Injection in patients with severe renal impairment
(creatinine clearance less than 30 mL/min) [see
Dosage and Administration (2.3)].
