A Study to Evaluate the Potential Benefit of the Addition of BYL719 to Paclitaxel in the Treatment of Breast Cancer and Head-and-neck Cancer
Study Details
Study Description
Brief Summary
Dose escalation part:to determine the highest dose of BYL719 administered on a daily basis when given in combination with weekly paclitaxel Dose escalation part: to confirm the safety and tolerability of the BYL719 and paclitaxel combination

Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: BYL719 and paclitaxel All patients enrolled in the study will receive BYL719 once daily plus weekly paclitaxel |
Drug: BYL719
BYL719 will be administered orally once daily on a continuous dosing schedule and dosed on a flat-fixed dose and not adjusted by body weight or body surface area, starting on Day 2 in the dose escalation part and Day 1 in the dose expansion part. In the dose escalation part, the BYL719 starting dose will be 300mg, with anticipated dose escalation to 350mg. In the dose expansion part, BYL719 will be administered at the recommended dose determined in the dose escalation part.
Drug: Paclitaxel
Paclitaxel will be administered once weekly at a dose of 80 mg/m2 i.v. (days 1, 8, 15 and 22) in a 28 day cycle in both dose escalation and expansion.

Outcome Measures
Primary Outcome Measures
- 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 tolerability [Screening, 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
- Dose escalation:Number of patients with adverse events as a measure of safety and tolerability [Screening, 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 escalation : BYL719 and Paclitaxel Plasma concentrations [Cycle 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 cohort [Baseline, 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: Progression free survival [Baseline, 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
- Dose expansion: Overall response rate [Baseline, 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 : Duration of Response [Baseline, 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 patients [Cycle 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.
