Study type | Interventional |
This open-label, dose-escalation study is designed to evaluate the safety, tolerability, pharmacokinetics, and preliminary efficacy of cobimetinib in pediatric and young adult participants with solid tumors with known or potential kinase pathway activation for which standard therapy has proven to be ineffective or intolerable or for which no curative standard-of-care treatment options exist. The study will be conducted in two stages: a dose-escalation stage and an expansion stage at the recommended dose.

Primary | Percentage of Participants With Adverse Events (AEs), Including Serious Adverse Events (SAEs) and Adverse Events of Special Interest (AESIs) | An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including abnormal laboratory values or abnormal clinical test results), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as AEs. | Baseline up until 30 days after the last dose of study drug (up to 5 years, 2 months) | |
