5 WARNINGS AND PRECAUTIONS Allergic Reactions: Monitor for development of rash, urticaria, erythema, pruritis, bronchospasm, and hypotension. (5.1) Neuropathy: Reduce the dose or discontinue oxaliplatin for injection if necessary. (5.2) Pulmonary Toxicity: May need to discontinue oxaliplatin for injection until interstitial lung disease or pulmonary fibrosis are excluded. (5.3) Hepatotoxicity: Monitor liver function tests. (5.4) Pregnancy. Fetal harm can occur when administered to a pregnant woman. Women should be apprised of the potential harm to the fetus. (5.5, 8.1) 5.1 Allergic Reactions See boxed warning Grade 3/4 hypersensitivity, including anaphylactic/anapylactoid reactions, to oxaliplatin for injection has been observed in 2 to 3% of colon cancer patients. These allergic reactions which can be fatal, can occur within minutes of administration and at any cycle, and were similar in nature and severity to those reported with other platinum-containing compounds, such as rash, urticaria, erythema, pruritus, and, rarely, bronchospasm and hypotension. The symptoms associated with hypersensitivity reactions reported in the previously untreated patients were urticaria, pruritus, flushing of the face, diarrhea associated with oxaliplatin infusion, shortness of breath, bronchospasm, diaphoresis, chest pains, hypotension, disorientation and syncope. These reactions are usually managed with standard epinephrine, corticosteroid, antihistamine therapy, and may require discontinuation of therapy. Drug-related deaths associated with platinum compounds from anaphylaxis have been reported. 5.2 Neuropathy Oxaliplatin for injection is associated with two types of neuropathy: An acute, reversible, primarily peripheral, sensory neuropathy that is of early onset, occurring within hours or one to two days of dosing, that resolves within 14 days, and that frequently recurs with further dosing. The symptoms may be precipitated or exacerbated by exposure to cold temperature or cold objects and they usually present as transient paresthesia, dysesthesia and hypoesthesia in the hands, feet, perioral area, or throat. Jaw spasm, abnormal tongue sensation, dysarthria, eye pain, and a feeling of chest pressure have also been observed. The acute, reversible pattern of sensory neuropathy was observed in about 56% of study patients who received oxaliplatin for injection with 5-fluorouracil/leucovorin. In any individual cycle acute neurotoxicity was observed in approximately 30% of patients. In adjuvant patients the median cycle of onset for grade 3 peripheral sensory neuropathy was 9 in the previously treated patients the median number of cycles administered on the oxaliplatin for injection with 5-fluorouracil/leucovorin combination arm was 6. An acute syndrome of pharyngolaryngeal dysesthesia seen in 1 to 2% (grade 3/4) of patients previously untreated for advanced colorectal cancer, and the previously treated patients, is characterized by subjective sensations of dysphagia or dyspnea, without any laryngospasm or bronchospasm (no stridor or wheezing). Ice (mucositis prophylaxis) should be avoided during the infusion of oxaliplatin for injection because cold temperature can exacerbate acute neurological symptoms. A persistent (>14 days), primarily peripheral, sensory neuropathy that is usually characterized by paresthesias, dysesthesias, hypoesthesias, but may also include deficits in proprioception that can interfere with daily activities (e.g., writing, buttoning, swallowing, and difficulty walking from impaired proprioception). These forms of neuropathy occurred in 48% of the study patients receiving oxaliplatin for injection with 5-fluorouracil/leucovorin. Persistent neuropathy can occur without any prior acute neuropathy event. The majority of the patients (80%) who developed grade 3 persistent neuropathy progressed from prior Grade 1 or 2 events. These symptoms may improve in some patients upon discontinuation of oxaliplatin for injection. In the adjuvant colon cancer trial, neuropathy was graded using a prelisted module derived from the Neuro-Sensory section of the National Cancer Institute Common Toxicity Criteria (NCI CTC) scale, Version 1, as follows: Table 1 - NCI CTC Grading for Neuropathy in Adjuvant Patients Grade Definition Grade 0 No change or none Grade 1 Mild paresthesias, loss of deep tendon reflexes Grade 2 Mild or moderate objective sensory loss, moderate paresthesias Grade 3 Severe objective sensory loss or paresthesias that interfere with function Grade 4 Not applicable Peripheral sensory neuropathy was reported in adjuvant patients treated with the oxaliplatin for injection combination with a frequency of 92% (all grades) and 13% (grade 3). At the 28-day follow-up after the last treatment cycle, 60% of all patients had any grade (Grade 1=40%, Grade 2=16%, Grade 3=5%) peripheral sensory neuropathy decreasing to 39% at 6 months follow-up (Grade 1=31%, Grade 2=7%, Grade 3=1%) and 21% at 18 months of follow-up (Grade 1=17%, Grade 2=3%, Grade 3=1%). In the advanced colorectal cancer studies, neuropathy was graded using a study-specific neurotoxicity scale, which was different from the NCI CTC scale, Version 2.0 (see below). Table 2 - Grading Scale for Paresthesias/Dysesthesias in Advanced Colorectal Cancer Patients Grade Definition Grade 1 Resolved and did not interfere with functioning Grade 2 Interfered with function but not daily activities Grade 3 Pain or functional impairment that interfered with daily activities Grade 4 Persistent impairment that is disabling or life-threatening Overall, neuropathy was reported in patients previously untreated for advanced colorectal cancer in 82% (all grades) and 19% (grade 3/4), and in the previously treated patients in 74% (all grades) and 7% (grade 3/4) events. Information regarding reversibility of neuropathy was not available from the trial for patients who had not been previously treated for colorectal cancer. 5.3 Pulmonary Toxicity Oxaliplatin for injection has been associated with pulmonary fibrosis (<1% of study patients), which may be fatal. The combined incidence of cough and dyspnea was 7.4% (any grade) and <1% (grade 3) with no grade 4 events in the oxaliplatin for injection plus infusional 5-fluorouracil/leucovorin arm compared to 4.5% (any grade) and no grade 3 and 0.1% grade 4 events in the infusional 5-fluorouracil/leucovorin alone arm in adjuvant colon cancer patients. In this study, one patient died from eosinophilic pneumonia in the oxaliplatin for injection combination arm. The combined incidence of cough, dyspnea and hypoxia was 43% (any grade) and 7% (grade 3 and 4) in the oxaliplatin for injection plus 5-fluorouracil/leucovorin arm compared to 32% (any grade) and 5% (grade 3 and 4) in the irinotecan plus 5-fluorouracil/leucovorin arm of unknown duration for patients with previously untreated colorectal cancer. In case of unexplained respiratory symptoms such as non-productive cough, dyspnea, crackles, or radiological pulmonary infiltrates, oxaliplatin for injection should be discontinued until further pulmonary investigation excludes interstitial lung disease or pulmonary fibrosis. 5.4 Hepatotoxicity Hepatotoxicity as evidenced in the adjuvant study, by increase in transaminases (57% vs. 34%) and alkaline phosphatase (42% vs. 20%) was observed more commonly in the oxaliplatin for injection combination arm than in the control arm. 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. Hepatic vascular disorders should be considered, and if appropriate, should be investigated in case of abnormal liver function test results or portal hypertension, which cannot be explained by liver metastases [see Clinical Trials Experience (6.1)]. 5.5 Use in Pregnancy Pregnancy Category D Oxaliplatin for injection may cause fetal harm when administered to a pregnant woman. There are no adequate and well-controlled studies of oxaliplatin for injection in pregnant women. Women of childbearing potential should be advised to avoid becoming pregnant while receiving treatment with oxaliplatin for injection. [see Use in Specific Populations (8.1)]. 5.6 Recommended Laboratory Tests Standard monitoring of the white blood cell count with differential, hemoglobin, platelet count, and blood chemistries (including ALT, AST, bilirubin and creatinine) is recommended before each oxaliplatin for injection cycle [see Dosage and Administration (2)]. There have been reports while on study and from post-marketing surveillance of prolonged prothrombin time and INR occasionally associated with hemorrhage in patients who received oxaliplatin for injection plus 5-fluorouracil/leucovorin while on anticoagulants. Patients receiving oxaliplatin for injection plus 5-fluorouracil/leucovorin and requiring oral anticoagulants may require closer monitoring.
