Study Endpoints

Primary Endpoints

Incidence of Dose Limiting Toxicities (DLT)
during the first cycle (28 days) of treatment with BYL719 and MEK162

Toxicity will be assessed using the National Cancer Institute (NCI) Common Toxicity Criteria for Adverse Events (CTCAE), version 4.0 unless otherwise specified. A DLT is defined as an adverse event or abnormal laboratory value assessed as at least possibly related to the study medication, occurs ≤ 28 days following the first dose of BYL719 and MEK162 (Cycle 1), and meets any of the protocol-specified DLT criteria.

Secondary Endpoints

Number of participants with adverse events and serious adverse events
Assessed from Cycle 1 Day 1 until treatment discontinuation
Overall response rate
Assessed every 8 weeks until disease progression
Time to progression
