PRIMARY OBJECTIVES:
I. To determine the safety and tolerability of GDC-0941 when given in combination with cisplatin in patients with androgen receptor-negative (AR-) triple negative (TN) metastatic breast cancer (MBC): assessment of dose limiting toxicities (DLTs) during the first 4 weeks of treatment (cycle 1); determination of the maximally tolerated dose (MTD) and recommended phase II dose of GDC-0941 given in combination with cisplatin. (Phase IB)
II. To evaluate the efficacy, as measured by the overall response rate (ORR), of cisplatin + GDC-0941 versus cisplatin alone in patients with AR- TN MBC. (Phase II)
SECONDARY OBJECTIVES:
I. To determine the clinical benefit rate (CBR) of cisplatin + GDC-0941 in patients with AR- TN MBC.
II. To determine the time to disease progression (TTP) of cisplatin + GDC-0941 versus cisplatin alone in patients with AR- TN MBC.
TERTIARY OBJECTIVES:
I. To characterize pharmacokinetics of GDC-0941 when administered in combination with cisplatin.
II. To explore predictors of response and mechanisms of resistance based on exploratory analysis of tumor tissue obtained through biopsies.
III. To assess the prognostic effects of phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha (PIK3CA) mutations and phosphatase and tensin homolog (PTEN) loss on TTP and CBR.
OUTLINE: This is a phase I, dose-deescalation study of PI3K inhibitor GDC-0941 followed by a randomized phase II study.
PHASE I: Patients receive cisplatin intravenously (IV) over 1 hour on days 1, 8, and 15 and PI3K inhibitor GDC-0941 orally (PO) once daily (QD) on days 2-6, 9-13, 16-20, and 23-27. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
PHASE II: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive cisplatin IV over 1 hour on days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients may crossover to Arm II upon disease progression.
ARM II: Patients receive cisplatin as in Arm I and PI3K inhibitor GDC-0941 PO QD on days 2-6, 9-13, 16-20, and 23-27. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 30 days.

Determine the safety and tolerability of GDC-0941 given in combination with cisplatin in patients with AR- TN MBC. Determination of the maximally tolerated dose (MTD) of GDC-0941. Cohort 1, 3 of 3 patients received: Cisplatin 25 mg/m2 IV D1, 8, 15 GDC-0941 260 mg PO, days 2-6, 9-13, 16-20, 23-27, 28 day cycle GDC-0941 dose to start at Max dose of 260mg. If no patient in the first cohort of 3 experiences a DLT, an additional cohort of 3 patients will be treated at the same dose level.

Maximum Tolerated Dose(MTD) of GDC-0941 and Recommended Phase II Dose of GDC-0941 Given in Combination With Cisplatin. - (Phase Ib)
Aikaikkuna: 4 weeks
|
GDC-0941 dose will start at 260 mg (maximum dose). De-escalation of the intensity of the dose (if necessary) will proceed among cohorts of 3 patients according to a standard 3+3 algorithm beginning at the highest dose level of GDC-0941 260mg. MTD is defined as the highest dose at which a DLT is experienced >= 1 out of 6 patients. A cohort of 3 patients was initially enrolled in the GDC-0941 arm at dose 260mg PO days 2-6, 9-13, 16-20, 23-27 of 28 day cycle

Percentage of Patients Achieving Overall Response - (Phase II)
Aikaikkuna: at 8 weeks
|
The primary efficacy endpoint is overall response rate (ORR) of cisplatin + GDC-0941 versus cisplatin alone in patients with AR- TN MBC. ORR is defined as the percentage of subjects achieving complete response (CR) plus partial response (PR) as their best response by RECIST version 1.1 for targeted lesions and assessed by CT, MRI scan. Objective responses, was estimated by the overall tumor burden at baseline (targeted lesions) in which subsequent measurements were performed every 8 weeks using the Solid Tumor Response Criteria (RECIST) v1.1 were compared. Complete Response (CR): Disappearance of all target lesions. Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. |
