( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Apotex Corp. at 1-800-706-5575 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. More than 1100 patients with stage II or III colon cancer and more than 4,000 patients with advanced colorectal cancer were treated in trials with oxaliplatin injection. The most common adverse reactions in patients with stage II or III colon cancer receiving adjuvant treatment were peripheral sensory neuropathy, neutropenia, thrombocytopenia, anemia, nausea, increase in transaminases and alkaline phosphatase, diarrhea, emesis, fatigue and stomatitis. The most common adverse reactions in previously untreated and treated patients with advanced colorectal cancer were peripheral sensory neuropathies, fatigue, neutropenia, nausea, emesis, and diarrhea. Adjuvant Treatment The safety of oxaliplatin injection in combination with fluorouracil (FU)/leucovorin (LV) was evaluated in patients with stage II or III colon cancer, who had undergone complete resection of the primary tumor in the adjuvant treatment trial [see Clinical Studies ( 14.1 )]. Fatal adverse reactions in patients who received oxaliplatin injection in the combination arm included sepsis/neutropenic sepsis (n=3), intracerebral hemorrhage (n=2) and eosinophilic pneumonia (n=1). Thromboembolic events occurred in 6% (grade 3-4, 1.2%) of patients in the oxaliplatin injection arm. Grade 3 or 4 adverse reactions occurred in 70% of patients in the oxaliplatin injection arm. Grade 3-4 gastrointestinal bleeding occurred in 0.2% of patients. Febrile neutropenia occurred in 0.7% and documented infection with concomitant grade 3-4 neutropenia occurred in 1.1%. Discontinuation due to an adverse reaction occurred in 15% of the patients in the oxaliplatin injection arm. Tables 5, 6, and 7 summarize the adverse reactions reported in patients with colon cancer receiving adjuvant treatment.

Drug Interactions
7 DRUG INTERACTIONS 7.1 Drugs that Prolong the QT Interval QT interval prolongation and ventricular arrhythmias can occur with oxaliplatin injection [see Warnings and Precautions ( 5.7 )] . Avoid coadministration of oxaliplatin injection with medicinal products with a known potential to prolong the QT interval. 7.2 Use with Nephrotoxic Drugs Because platinum-containing species are eliminated primarily through the kidney, clearance of these products may be decreased by coadministration of potentially nephrotoxic compounds [see Clinical Pharmacology ( 12.3 )]. Avoid coadministration of oxaliplatin injection with medicinal products known to cause nephrotoxicity. 7.3 Use with Anticoagulants Prolonged prothrombin time and INR occasionally associated with hemorrhage have been reported in patients who received oxaliplatin injection with fluorouracil/leucovorin while on anticoagulants [see Warnings and Precautions ( 5.10 ), Adverse Reactions ( 6.2 )]. Increase frequency of monitoring in patients who are receiving oxaliplatin injection with fluorouracil/leucovorin and oral anticoagulants.
Clinical Pharmacology
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Oxaliplatin undergoes nonenzymatic conversion in physiologic solutions to active derivatives via displacement of the labile oxalate ligand. Several transient reactive species are formed, including monoaquo and diaquo DACH platinum, which covalently bind with macromolecules. Both inter- and intrastrand Pt-DNA crosslinks are formed. Crosslinks are formed between the N7 positions of two adjacent guanines (GG), adjacent adenine-guanines (AG), and guanines separated by an intervening nucleotide (GNG). These crosslinks inhibit DNA replication and transcription. Cytotoxicity is cell-cycle nonspecific. In vivo studies have shown antitumor activity of oxaliplatin against colon carcinoma. In combination with fluorouracil, oxaliplatin exhibits in vitro and in vivo antiproliferative activity greater than either compound alone in several tumor models (HT29 [colon], GR [mammary], and L1210 [leukemia]). 12.2 Pharmacodynamics A pharmacodynamic relationship between platinum ultrafiltrate levels and clinical safety and effectiveness has not been established. 12.3 Pharmacokinetics The reactive oxaliplatin derivatives are present as a fraction of the unbound platinum in plasma ultrafiltrate. After a single 2-hour intravenous infusion of oxaliplatin injection at a dose of 85 mg/m 2 , pharmacokinetic parameters expressed as ultrafiltrable platinum were C max of 0.814 mcg/mL and volume of distribution of 440 L. Interpatient and intrapatient variability in ultrafiltrable platinum exposure (AUC 0-48hr ) assessed over 3 cycles was 23% and 6%, respectively. Distribution At the end of a 2-hour infusion of oxaliplatin injection, approximately 15% of the administered platinum is present in the systemic circulation. The remaining 85% is rapidly distributed into tissues or eliminated in the urine. The decline of ultrafiltrable platinum levels following oxaliplatin injection administration is triphasic, including two distribution phases (t 1/2α ; 0.43 hours and t 1/2β ; 16.8 hours). In patients, plasma protein binding of platinum is irreversible and is greater than 90%. The main binding proteins are albumin and gamma-globulins. Platinum also binds irreversibly and accumulates (approximately 2-fold) in erythrocytes, where it appears to have no relevant activity. No platinum accumulation was observed in plasma ultrafiltrate following 85 mg/m 2 every two weeks. Elimination The decline of ultrafiltrable platinum concentrations from plasma is characterized by a long terminal elimination phase (t 1/2 γ ; 392 hours). Metabolism Oxaliplatin undergoes rapid and extensive nonenzymatic biotransformation. There is no evidence of cytochrome P450-mediated metabolism in vitro. Up to 17 platinum-containing derivatives have been observed in plasma ultrafiltrate samples from patients, including several cytotoxic species (monochloro DACH platinum, dichloro DACH platinum, and monoaquo and diaquo DACH platinum) and a number of noncytotoxic, conjugated species. Excretion The major route of platinum elimination is renal excretion. At five days after a single 2-hour infusion of oxaliplatin injection, urinary elimination accounted for about 54% of the platinum eliminated, with fecal excretion accounting for only about 2%. Platinum was cleared from plasma at a rate (10-17 L/h) that was similar to or exceeded the average human glomerular filtration rate (GFR; 7.5 L/h). The renal clearance of ultrafiltrable platinum is significantly correlated with GFR. Special Populations Sex There was no significant effect of sex on the clearance of ultrafiltrable platinum. Patients with renal impairment Patients with normal function (CLcr greater than 80 mL/min) and patients with mild (CLcr=50-80 mL/min) and moderate (CLcr equal to 30-49 mL/min) renal impairment received oxaliplatin injection 85 mg/m 2 and those with severe (CLcr less than 30 mL/min) renal impairment received oxaliplatin injection 65 mg/m 2 . Mean dose adjusted AUC of unbound platinum was 40%, 95%, and 342% higher for patients with mild, moderate, and severe renal impairment, respectively, compared to patients with normal renal function. Mean dose adjusted C max of unbound platinum appeared to be similar among the normal, mild and moderate renal function groups, but was 38% higher in the severe group than in the normal group [see Dosage and Administration ( 2.3 )] . Drug Interaction Studies No pharmacokinetic interaction between oxaliplatin injection 85 mg/m 2 and infusional fluorouracil has been observed in patients treated every 2 weeks, but increases of fluorouracil plasma concentrations by approximately 20% have been observed with doses of 130 mg/m 2 of oxaliplatin injection administered every 3 weeks. In vitro platinum was not displaced from plasma proteins by the following medications: erythromycin, salicylate, sodium valproate, granisetron, and paclitaxel. In vitro oxaliplatin does not inhibit human cytochrome P450 isoenzymes.
Mechanism Of Action
12.1 Mechanism of Action Oxaliplatin undergoes nonenzymatic conversion in physiologic solutions to active derivatives via displacement of the labile oxalate ligand. Several transient reactive species are formed, including monoaquo and diaquo DACH platinum, which covalently bind with macromolecules. Both inter- and intrastrand Pt-DNA crosslinks are formed. Crosslinks are formed between the N7 positions of two adjacent guanines (GG), adjacent adenine-guanines (AG), and guanines separated by an intervening nucleotide (GNG). These crosslinks inhibit DNA replication and transcription. Cytotoxicity is cell-cycle nonspecific. In vivo studies have shown antitumor activity of oxaliplatin against colon carcinoma. In combination with fluorouracil, oxaliplatin exhibits in vitro and in vivo antiproliferative activity greater than either compound alone in several tumor models (HT29 [colon], GR [mammary], and L1210 [leukemia]).

Carcinogenesis And Mutagenesis And Impairment Of Fertility
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Long-term animal studies have not been performed to evaluate the carcinogenic potential of oxaliplatin. Oxaliplatin was not mutagenic to bacteria (Ames test) but was mutagenic to mammalian cells in vitro (L5178Y mouse lymphoma assay). Oxaliplatin was clastogenic both in vitro (chromosome aberration in human lymphocytes) and in vivo (mouse bone marrow micronucleus assay). In a fertility study, male rats were given oxaliplatin at 0, 0.5, 1, or 2 mg/kg/day for five days every 21 days for a total of three cycles prior to mating with females that received two cycles of oxaliplatin on the same schedule. A dose of 2 mg/kg/day (less than one-seventh the recommended human dose on a body surface area basis) did not affect pregnancy rate, but resulted in 97% postimplantation loss (increased early resorptions, decreased live fetuses, decreased live births) and delayed growth (decreased fetal weight). Testicular damage, characterized by degeneration, hypoplasia, and atrophy, was observed in dogs administered oxaliplatin at 0.75 mg/kg/day (approximately one-sixth of the recommended human dose on a body surface area basis)x 5 days every 28 days for three cycles. A no effect level was not identified.

Clinical Studies
14 CLINICAL STUDIES 14.1 Adjuvant Treatment with Oxaliplatin Injection in Combination with Fluorouracil and Leucovorin The efficacy of oxaliplatin injection in combination with fluorouracil (FU)/leucovorin (LV) was evaluated in an international, multicenter, randomized (1:1) trial (The Multicenter International Study of Oxaliplatin/5-Fluorouracil/Leucovorin in the Adjuvant Treatment of Colon Cancer [MOSAIC], NCT00275210) in patients with stage II (Dukes' B2) or III (Dukes' C) colon cancer who had undergone complete resection of the primary tumor. Patients were randomized to receive oxaliplatin injection with fluorouracil/leucovorin or fluorouracil/leucovorin alone for a total of 6 months (i.e., 12 cycles). Table 14 shows the dosing regimens for the two arms. Eligible patients were between 18 and 75 years of age, had histologically proven stage II (T 3 -T 4 N0 M0; Dukes' B2) or III (any T N 1-2 M0; Dukes' C) colon carcinoma (with the inferior pole of the tumor above the peritoneal reflection, i.e., greater than or equal to 15 cm from the anal margin) and had undergone (within 7 weeks prior to randomization) complete resection of the primary tumor without gross or microscopic evidence of residual disease and carcino-embyrogenic antigen (CEA) less than 10 ng/mL. Additional eligibility criteria were no prior chemotherapy, immunotherapy or radiotherapy; Eastern Cooperative Oncology Group performance status of 0, 1, or 2 (Karnofsky Performance Status greater than or equal to 60%); no pre-existing neuropathy; and absolute neutrophil count (ANC) greater than or equal to 1.5x10 9 /L, platelets greater than or equal to 100 x 10 9 /L, serum creatinine less than or equal to 1.25 x upper limit normal (ULN), total bilirubin less than 2 x ULN, and aspartate transaminase (AST)/alanine transaminase (ALT) less than 2 x ULN. The major efficacy outcome was 3-year disease-free survival (DFS).

The trial included 7 arms at different times during its conduct, four of which were closed due to either changes in the standard of care, toxicity, or simplification. During the trial, the control arm was changed to irinotecan with fluorouracil/leucovorin. The results reported below compared the efficacy of oxaliplatin injection with fluorouracil/leucovorin and oxaliplatin injection with irinotecan to an approved control regimen of irinotecan with fluorouracil/leucovorin in 795 concurrently randomized patients previously untreated for locally advanced or metastatic colorectal cancer. Table 19 presents the dosing regimens for the three arms. After completion of enrollment, the dose of irinotecan with fluorouracil/leucovorin was decreased due to toxicity. Eligible patients were at least 18 years of age; had known locally advanced, locally recurrent, or metastatic colorectal adenocarcinoma not curable by surgery or amenable to radiation therapy; with an Eastern Cooperative Oncology Group (ECOG) performance status ≤0, 1, or 2. Patients had to have absolute neutrophil count (ANC) greater than or equal to 1.5 × 10 9 /L, platelets greater than or equal to 100 x 10 9 /L, hemoglobin greater than or equal to 9.0 g/dL, creatinine less than or equal to 1.5 x upper limit of normal (ULN), total bilirubin less than or equal to 1.5 mg/dL, aspartate transaminase (AST) less than or equal to 5 x ULN, and alkaline phosphatase less than or equal to 5 x ULN. Patients may have received adjuvant treatment for resected Stage II or III disease without recurrence within 12 months. Randomization was stratified by ECOG performance status (0, 1 vs 2), prior adjuvant chemotherapy (yes vs no), prior immunotherapy (yes vs no), and age (less than 65 vs greater than or equal to 65 years). Although no post study treatment was specified in the protocol, 65% to 72% of patients received additional post study chemotherapy after study treatment discontinuation on all arms. Fifty-eight percent of patients on the oxaliplatin injection with fluorouracil/leucovorin arm received an irinotecan-containing regimen and 23% of patients on the irinotecan with fluorouracil/leucovorin arm received an oxaliplatin-containing regimen. The main efficacy outcome measure was 3-year disease-free survival (DFS) and additional efficacy outcome measures were overall survival (OS).

Figure 3 14.3 Previously Treated Advanced Colorectal Cancer The efficacy of oxaliplatin injection in combination with fluorouracil (FU)/leucovorin (LV) was evaluated in a multicenter, open-label, randomized, three-arm controlled trial was conducted in the US and Canada in patients with advanced colorectal cancer who had relapsed/progressed during or within 6 months of first-line treatment with bolus fluorouracil/leucovorin and irinotecan (A multicenter, open-label, randomized, three-arm study of 5-fluorouracil (5-FU) + leucovorin (LV) or oxaliplatin or a combination of 5-FU/LV + oxaliplatin as second-line treatment of metastatic colorectal carcinoma: NCT00008281). Patients were randomized to one of three regimens; the dosing regimens are presented in Table 22. Eligible patients were at least 18 years of age, had unresectable, measurable, histologically proven colorectal adenocarcinoma, with a Karnofsky performance status (KPS) greater than 50%. Patients had to have aspartate transaminase (AST), alanine transaminase (ALT) and alkaline phosphatase less than or equal to 2x upper limit of normal (ULN), unless liver metastases were present and documented at baseline by CT or MRI scan, in which case less than or equal to 5x ULN was permitted. Prior radiotherapy was permitted if it had been completed at least 3 weeks before randomization. The main efficacy outcome measure was 3-year disease-free survival (DFS) and an additional outcome measure was overall survival (OS).

Geriatric Use
8.4 Pediatric Use The safety and effectiveness of oxaliplatin injection in pediatrics have not been established. Safety and effectiveness were assessed across 4 open-label studies in 235 patients aged 7 months to 22 years with solid tumors. In a multicenter, open-label, non-comparative, non-randomized study (ARD5531), oxaliplatin was administered to 43 patients with refractory or relapsed malignant solid tumors, mainly neuroblastoma and osteosarcoma. The dose limiting toxicity (DLT) was sensory neuropathy at a dose of 110 mg/m 2 . The main adverse reactions were: paresthesia (60%, grade 3-4: 7%), fever (40%, grade 3-4: 7%), and thrombocytopenia (40%, grade 3-4: 27%). No responses were observed. In an open-label non-randomized study (DFI7434), oxaliplatin was administered to 26 pediatric patients with metastatic or unresectable solid tumors, mainly neuroblastoma and ganglioneuroblastoma. The DLT was sensory neuropathy at a dose of 160 mg/m 2 . No responses were observed. In an open-label, single-agent study (ARD5021), oxaliplatin was administered to 43 pediatric patients with recurrent or refractory embryonal CNS tumors. The most common adverse reactions reported were: leukopenia (67%, grade 3-4: 12%), anemia (65%, grade 3-4: 5%), thrombocytopenia (65%, grade 3-4: 26%), vomiting (65%, grade 3-4: 7%), neutropenia (58%, grade 3-4: 16%), and sensory neuropathy (40%, grade 3-4: 5%). In an open-label single-agent study (ARD5530), oxaliplatin was administered to 123 pediatric patients with recurrent solid tumors, including neuroblastoma, osteosarcoma, Ewing sarcoma or peripheral PNET, ependymoma, rhabdomyosarcoma, hepatoblastoma, high grade astrocytoma, Brain stem glioma, low grade astrocytoma, malignant germ cell tumor and other tumors. The most common adverse reactions reported were: sensory neuropathy (52%, grade 3-4: 12%), thrombocytopenia (37%, grade 3-4: 17%), anemia (37%, grade 3-4: 9%), vomiting (26%, grade 3-4: 4%), increased ALT (24%, grade 3-4: 6%), increased AST (24%, grade 3-4: 2%), and nausea (23%, grade 3-4: 3%). The pharmacokinetic parameters of ultrafiltrable platinum were evaluated in 105 pediatric patients during the first cycle. The mean clearance in pediatric patients estimated by the population pharmacokinetic analysis was 4.7 L/h (%CV, 41%). Mean platinum pharmacokinetic parameters in ultrafiltrate were C max of 0.75 ± 0.24 mcg/mL, AUC 0-48h of 7.52 ± 5.07 mcg∙h/mL and AUC inf of 8.83 ± 1.57 mcg∙h/mL at 85 mg/m 2 of oxaliplatin and C max of 1.10 ± 0.43 mcg/mL, AUC 0-48h of 9.74 ± 2.52 mcg∙h/mL and AUC inf of 17.3 ± 5.34 mcg∙h/mL at 130 mg/m 2 of oxaliplatin.
Nursing Mothers
8.2 Lactation Risk Summary There are no data on the presence of oxaliplatin or its metabolites in human or animal milk or its effects on the breastfed infant or on milk production. Because of the potential for serious adverse reactions in breastfed infants, advise women not to breastfeed during treatment with oxaliplatin injection and for 3 months after the final dose.
Pediatric Use
8.3 Females and Males of Reproductive Potential Pregnancy Testing Verify pregnancy status in females of reproductive potential prior to initiating oxaliplatin injection [see Use in Specific Populations ( 8.1 )] . Contraception Oxaliplatin Injection can cause embryo-fetal harm when administered to a pregnant woman [see Use in Specific Populations ( 8.1 )] . Females Advise female patients of reproductive potential to use effective contraception while receiving oxaliplatin injection and for 9 months after the final dose. Males Based on its mechanism action as a genotoxic drug, advise males with female partners of reproductive potential to use effective contraception while receiving oxaliplatin injection and for 6 months after the final dose [see Nonclinical Toxicology ( 13.1 )] . Infertility Based on animal studies, oxaliplatin injection may impair fertility in males and females [see Nonclinical Toxicology ( 13.1 )] .
Pregnancy
8.1 Pregnancy Risk Summary Based on its direct interaction with DNA, oxaliplatin injection can cause fetal harm when administered to a pregnant woman. The available human data do not establish the presence or absence of major birth defects or miscarriage related to the use of oxaliplatin injection. Reproductive toxicity studies demonstrated adverse effects on embryo-fetal development in rats at maternal doses that were below the recommended human dose based on body surface area (see Data) . Advise a pregnant woman 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 is 2% to 4% and 15% to 20%, respectively. Data Animal data Pregnant rats were administered oxaliplatin at less than one-tenth the recommended human dose based on body surface area during gestation days (GD)1-5 (preimplantation), GD 6-10, or GD 11-16 (during organogenesis). Oxaliplatin caused developmental mortality (increased early resorptions) when administered on days GD 6-10 and GD 11-16 and adversely affected fetal growth (decreased fetal weight, delayed ossification) when administered on days GD 6-10.

The effect of oxaliplatin injection in patients greater than or equal to 65 years was not conclusive. Patients greater than or equal to 65 years receiving oxaliplatin injection 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 injection 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 injection 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 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 )].
