Interventions

Primary outcome

1. Number of Participants With Dose Limiting Toxicities (DLTs)

   Time frame: Cycle 1 (28 Days)

   DLT is defined as 1 of the following toxicities considered by the investigator to be possibly related to study drugs: a) Grade (G) ≥3 febrile neutropenia, b) G ≥4 neutropenia (absolute neutrophil count [ANC] <500/ microliter [μL]) lasting >5 days , c) G ≥4 thrombocytopenia lasting >2 days, d) G ≥4 anemia, e) G ≥3 elevation of total bilirubin or hepatic transaminase or alkaline phosphatase (ALP) lasting >3 days, f) Hepatic transaminases >3 × Upper Limit of Normal (ULN) and an increase in total bilirubin >2 × ULN without any findings of cholestasis and in the absence of other contributory factors, g) G ≥2 visual changes that do not resolve to baseline within 14 days, h) 1 episode of fasting G 4 hyperglycemia or 3 episodes of fasting, i) G 3 hyperglycemia on separate days within 7 days, j) G ≥4 fasting hypercholesterolemia or triglyceridemia for ≥2 weeks, k) G ≥3 nausea, vomiting, or diarrhea despite maximal supportive medications lasting for ≥3 days.

2. Number of DLTs Categorized as Per the Nature

   Time frame: Cycle 1 (28 Days)

   DLT is defined as 1 of the following toxicities considered by the investigator to be possibly related to study drugs: a) G ≥3 febrile neutropenia, b) G ≥4 neutropenia (ANC <500/μL) lasting >5 days , c) G ≥4 thrombocytopenia lasting >2 days, d) G ≥4 anemia, e) G ≥3 elevation of total bilirubin or hepatic transaminase or ALP lasting >3 days, f) Hepatic transaminases >3 × ULN and an increase in total bilirubin >2 × ULN without any findings of cholestasis and in the absence of other contributory factors, g) G ≥2 visual changes that do not resolve to baseline within 14 days, h) 1 episode of fasting G 4 hyperglycemia or 3 episodes of fasting, i) G 3 hyperglycemia on separate days within 7 days, j) G ≥4 fasting hypercholesterolemia or triglyceridemia for ≥2 weeks, k) G ≥3 nausea, vomiting, or diarrhea despite maximal supportive medications lasting for ≥3 days. Hematologic, Hepatic and non-hematologic and non-hepatic DLT categories were to be reported.

3. Maximum Tolerated Doses (MTDs) in Combination of Cobimetinib and Ipatasertib During Dose-Escalation Stage 1

   Time frame: Cycle 1 (28 Days)

   An adverse event (AE) is any unfavorable and unintended sign, symptom, or disease temporally associated with the use of an investigational medicinal product (IMP) or other protocol-imposed intervention, regardless of attribution. On the basis of AEs that did not meet protocol-defined DLT criteria (defined in Outcome measure 1) but indicated intolerability of a given dose combination, the combination MTDs were determined (as per investigator) during Stage 1 of the study.

4. Number of Participants With At Least One AE Graded According to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), Version (V) 4.0

   Time frame: From Baseline up to 30 days after the last dose of study treatment or until initiation of another anticancer treatment whichever occurred first (Up to 33 months)

   AE was defined in Outcome Measure 3. AEs were graded as per NCI CTCAE V 4.0 as follows: G 1: asymptomatic or mild symptoms, clinical or diagnostic observations only, intervention not indicated; G 2: minimal, local or noninvasive intervention indicated, limiting age-appropriate instrumental activities of daily living (ADL) (instrumental ADL refers to preparing meals, shopping for groceries or clothes, using the telephone, managing money and others); G 3: severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated, disabling, limiting self care ADL (refers to bathing, dressing and undressing, feeding self, using the toilet, taking medications, and not bedridden); G 4: Life-threatening consequences, urgent intervention indicated; G 5: Death related to AE. If a participant had multiple events of different grades, the highest grade that occurred in that participant was counted.
