Primary Outcome Measures
NameTimeMethod
Dose escalation : Dose Limiting Toxicity (DLT)Cycle 1 (28 days)

A dose-limiting toxicity (DLT) is an adverse event or abnormal laboratory value assessed as being unrelated to disease, disease progression, inter-current illness, or concomitant medications, and that occurs within the first cycle of treatment with BYL719 plus paclitaxel and meets any of the pre-defined criteria.

Dose expansion : Number of patients with adverse events as a measure of safety and tolerabilityScreening, every 28 days until 30 days after last dose

type, intensity, severity and seriousness of adverse events according to the NCI CTC AE v4.03. Dose interruptions, reductions and dose intensity.

Secondary Outcome Measures
NameTimeMethod
Dose escalation : BYL719 and Paclitaxel Plasma concentrationsCycle 1 Day 1, Cycle 1 Day 2, Cycle 1 Day 8, Cycle 1 Day 9

Plasma concentration time profiles of BYL719 and paclitaxel. Plasma PK parameters of paclitaxel (single agent vs. combination) and BYL719 (steady state in combination with paclitaxel).

Dose expansion: Clinical benefit Rate in the breast cancer cohortBaseline, every 8 weeks (Breast cancer patients) from start of treatment until first documented disease progression up to 2 years

Clinical benefit rate is defined as the proportion of patients with a best overall response of complete response (CR) or partial response (PR) or stable disease (SD) for more than 24 weeks of duration of response.

Dose expansion : Duration of ResponseBaseline, every 6 weeks (HNSCC patients) or every 8 weeks (breast cancer patients) from start of treatment until first documented disease progression up to 2 years

Duration of response is defined as the time of first occurrence of CR or PR until the date of the first documented disease progression or death due to the disease.

Dose expansion: Plasma pharmacokinetics of BYL719 given in combination with paclitaxel in breast cancer and HNSCC patientsCycle 1 Day 1, Cycle 1 Day 8, Cycle 2 Day 15, and Day 1 of each subsequent Cycle

Plasma concentration time profiles of BYL719 and appropriate individual PK parameters.

Dose escalation:Number of patients with adverse events as a measure of safety and tolerabilityScreening, every 28 days until 30 days after last dose

type, intensity, severity and seriousness of adverse events according to the NCI CTC AE v4.03. Dose interruptions, reductions and dose intensity.

Dose expansion: Overall response rateBaseline, every 6 weeks (HNSCC patients) or every 8 weeks (Breast cancer patients) from start of treatment until first documented disease progression up to 2 years

Overall response rate is defined as the proportion of patients with a best overall response of complete response (CR) or partial response (PR), based on RECIST 1.1 criteria and the investigator assessment.

Dose expansion: Progression free survivalBaseline, every 6 weeks (head-and-neck squamous cell carcinoma (HNSCC) patients) or every 8 weeks (Breast cancer patients) from start of treatment until first documented disease progression up to 2 years

Progression-free survival is defined as the time from start date of study treatment until objective tumor progression or death from any cause
