Experimental: LJM716, BYL719 AND TRASTUZUMAB
A treatment cycle will consist of 28 days. Treatment doses for trastuzumab and LJM716 will be fixed at trastuzumab 2mg/kg weekly, and LJM716 20mg/kg weekly. The exception to this is if dose de-escalation results in treatment of patients at dose level 1, where LJM will be dosed at 10mg/kg weekly. On Arm A, BYL719 was administered orally once daily continuously at one of 5 dosing levels, beginning with dose level 3, 250mg orally daily. On Arm B, BYL719 will be administered orally once daily during 4 of 7 days in a week, at one of 5 dosing levels, beginning with dose level 3, 250mg orally daily. This means BYL719 will be given to patients on Arm B during days 1-4, 8-11, 15-18, and 22-25 of each cycle. The dose-finding phase will follow a Continuous Reassessment Methods (CRM) phase I biostatistical design.
- maximum tolerated dose (MTD) of BYL719 [ Time Frame: 1 year ]
- recommended dose for expansion (RDE) [ Time Frame: 1 year ]The MTD is defined as per the Continual Reassessment Method. The RDE will be determined by the Principal Investigator with input from other investigators and Novartis, and will be based on the MTD, review of required intra-patient dose de-escalations, pharmacodynamic evaluations, and consideration of toxicities occurring in cycles 2+.
- Toxicity will be assessed using the NCI Common Toxicity Criteria, version 4.0, unless otherwise specified. The type, severity, timing and relationship of each adverse event will be documented. [ Time Frame: 2 years ]

- or have had surgical bilateral oophorectomy (with or without hysterectomy) For women with therapy-induced amenorrhea, oophorectomy or serial measurements of FSH and/or estradiol are needed to ensure postmenopausal status. NOTE: Ovarian radiation or treatment with a luteinizing hormone-releasing hormone (LH-RH) agonist (goserelin acetate or leuprolide acetate) is not permitted for induction of ovarian suppression.
