Adverse reactions
6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the label: New Primary Cutaneous Malignancies [see Warnings and Precautions (5.1)] Hemorrhage [see Warnings and Precautions (5.2)] Cardiomyopathy [see Warnings and Precautions (5.3)] Serious Dermatologic Reactions [see Warnings and Precautions (5.4)] Serous Retinopathy and Retinal Vein Occlusion [see Warnings and Precautions (5.5)] Hepatotoxicity [see Warnings and Precautions (5.6)] Rhabdomyolysis [see Warnings and Precautions (5.7)] Severe Photosensitivity [see Warnings and Precautions (5.8)] Most common adverse reactions for COTELLIC (≥20%) are diarrhea, photosensitivity reaction, nausea, pyrexia, and vomiting. The most common (≥5%) Grade 3-4 laboratory abnormalities are increased GGT, increased CPK, hypophosphatemia, increased ALT, lymphopenia, increased AST, increased alkaline phosphatase, hyponatremia. (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Genentech at 1-888-835-2555 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. The safety of COTELLIC was evaluated in Trial 1, a randomized (1:1), double-blind, active-controlled trial in previously untreated patients with BRAF V600 mutation-positive, unresectable or metastatic melanoma [see Clinical Studies (14)]. All patients received vemurafenib 960 mg twice daily on Days 1–28 and received either COTELLIC 60 mg once daily (n=247) or placebo (n=246) on Days 1–21 of each 28-day treatment cycle until disease progression or unacceptable toxicity. In the COTELLIC plus vemurafenib arm, 66% percent of patients were exposed for greater than 6 months and 24% of patients were exposed for greater than 1 year. Patients with abnormal liver function tests, history of acute coronary syndrome within 6 months, evidence of Class II or greater congestive heart failure (New York Heart Association), active central nervous system lesions, or evidence of retinal pathology were excluded from Trial 1. The demographics and baseline tumor characteristics of patients enrolled in Trial 1 are summarized in Clinical Studies [see Clinical Studies (14)]. In Trial 1, 15% of patients receiving COTELLIC experienced an adverse reaction that resulted in permanent discontinuation of COTELLIC. The most common adverse reactions resulting in permanent discontinuation were liver laboratory abnormalities defined as increased aspartate aminotransferase (AST) (2.4%), increased gamma glutamyltransferase (GGT) (1.6%) and increased alanine aminotransferase (ALT) (1.6%); rash (1.6%); pyrexia (1.2%); and retinal detachment (2%). Among the 247 patients receiving COTELLIC, adverse reactions led to dose interruption or reductions in 55%. The most common reasons for dose interruptions or reductions of COTELLIC were rash (11%), diarrhea (9%), chorioretinopathy (7%), pyrexia (6%), vomiting (6%), nausea (5%), and increased creatine phosphokinase (CPK) (4.9%). The most common (≥20%) adverse reactions with COTELLIC were diarrhea, photosensitivity reaction, nausea, pyrexia, and vomiting. Table 3.

Use in special populations
8 USE IN SPECIFIC POPULATIONS Lactation: Do not breastfeed while taking COTELLIC. (8.2) 8.1 Pregnancy Risk Summary Based on findings from animal reproduction studies and its mechanism of action, COTELLIC can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no available data on the use of COTELLIC during pregnancy. In animal reproduction studies, oral administration of cobimetinib in pregnant rats during organogenesis was teratogenic and embryotoxic at exposures (AUC) that were 0.9 to 1.4-times those observed in humans at the recommended human dose of 60 mg [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 is 2–4% and 15–20%, respectively. Data Animal Data Administration of cobimetinib to pregnant rats during the period of organogenesis resulted in increased post-implantation loss, including total litter loss, at exposures (AUC) of 0.9–1.4 times those in humans at the recommended dose of 60 mg. Post-implantation loss was primarily due to early resorptions. Fetal malformations of the great vessels and skull (eye sockets) occurred at the same exposures. 8.2 Lactation Risk Summary There is no information regarding the presence of cobimetinib in human milk, effects on the breastfed infant, or effects on milk production. Because of the potential for serious adverse reactions in a breastfed infant, advise a nursing woman not to breastfeed during treatment with COTELLIC and for 2 weeks after the final dose. 8.3 Females and Males of Reproductive Potential Contraception Females COTELLIC can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)]. Advise females of reproductive potential to use effective contraception during treatment with COTELLIC and for 2 weeks after the final dose of COTELLIC. Infertility Females and Males Based on findings in animals, COTELLIC may reduce fertility in females and males of reproductive potential [see Nonclinical Toxicology (13.1)]. 8.4 Pediatric Use The safety and effectiveness of COTELLIC have not been established in pediatric patients. Juvenile Animal Data In a 4-week juvenile rat toxicology study, daily oral doses of 3 mg/kg (approximately 0.13–0.5 times the adult human AUC at the recommended dose of 60 mg) between postnatal Days 10–17 (approximately equivalent to ages 1–2 years in humans) were associated with mortality, the cause of which was not defined. 8.5 Geriatric Use Clinical studies of cobimetinib did not include sufficient numbers of patients aged 65 years and older to determine whether they respond differently from younger patients. 8.6 Hepatic Impairment Adjustment in the starting dose of COTELLIC is not required in patients with mild (Child-Pugh score A), moderate (Child-Pugh B) or severe (Child-Pugh C) hepatic impairment [see Clinical Pharmacology (12.3)]. 8.7 Renal Impairment No dedicated pharmacokinetic trial in patients with renal impairment has been conducted. Dose adjustment is not recommended for mild to moderate renal impairment (CLcr 30 to 89 mL/min) based on the results of the population pharmacokinetic analysis. A recommended dose has not been established for patients with severe renal impairment [see Clinical Pharmacology (12.3)].

Interactions

7 DRUG INTERACTIONS Avoid concomitant administration of COTELLIC with strong or moderate CYP3A inducers or inhibitors. (2.3, 7.1, 7.2) 7.1 Effect of Strong or Moderate CYP3A Inhibitors on Cobimetinib Coadministration of COTELLIC with itraconazole (a strong CYP3A4 inhibitor) increased cobimetinib systemic exposure by 6.7-fold. Avoid concurrent use of COTELLIC and strong or moderate CYP3A inhibitors. If concurrent short term (14 days or less) use of moderate CYP3A inhibitors including certain antibiotics (e.g., erythromycin, ciprofloxacin) is unavoidable for patients who are taking COTELLIC 60 mg, reduce COTELLIC dose to 20 mg. After discontinuation of a moderate CYP3A inhibitor, resume COTELLIC at the previous dose [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)]. Use an alternative to a strong or moderate CYP3A inhibitor in patients who are taking a reduced dose of COTELLIC (40 or 20 mg daily) [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)]. 7.2 Effect of Strong or Moderate CYP3A Inducers on Cobimetinib Coadministration of COTELLIC with a strong CYP3A inducer may decrease cobimetinib systemic exposure by more than 80% and reduce its efficacy. Avoid concurrent use of COTELLIC and strong or moderate CYP3A inducers including but not limited to carbamazepine, efavirenz, phenytoin, rifampin, and St. John's Wort [see Clinical Pharmacology (12.3)].
