Trial Outcomes & Findings for GDC-0941 and Cisplatin in Treating Patients With Androgen Receptor-Negative Triple Negative Metastatic Breast Cancer (NCT NCT01918306)
NCT ID: NCT01918306
Last Updated: 2017-06-27
Results Overview
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 1. 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. 2. If 1 patient experiences a DLT in the first cohort, an additional cohort of 3 patients will be treated at the same dose level. 3. If ≤1 patient has a DLT in 6 treated at this same dose, this will be considered a tolerable dose to move to phase II. 4. If 2 or more patients in 3 or 6 patients treated at a given dose experience DLT, the dose will be de-escalated to the next lower dose level.

PRIMARY outcome
Timeframe: at 8 weeksPopulation: Phase 1-Initial and Max tolerated dose of GCD-0941 was the same, no dose de-escalation occurred. Phase 2, 1 of the 2 patients from the Cisplatin only arm did crossover to the Crossover Cisplatin and GDC-0941 arm. 3 patients randomized to Cisplatin + GDC -0941 arm, and 1 crossover patient, for a total of 4 patients who received Cisplatin+GDC-0941.
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.

Timeframe: at 32 weeksPopulation: Study closed early and response and progression were not evaluated at 32 weeks.
Clinical Benefit Rate (CBR) is defined as complete response (CR) plus partial response (PR) plus stable disease (SD) for 6 months. Clinical Benefit Rate (CBR) is calculated with the corresponding 95% confidence intervals at the dose recommended for phase II. Response and progression will be evaluated using the international criteria proposed by the revised Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 performed at baseline and every 8 weeks will be compared.

1PHIbA - Arm A - Cisplatin + GDC - 0941 Dose Level 1
n=6 participants at risk
Patients cohort 1 receive cisplatin and PI3K inhibitor GDC-0941. Courses repeat in the absence of disease progression or unacceptable toxicity.
cisplatin: 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.
PI3K inhibitor: GDC-0941 orally (PO) one time a day (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.
If no patients in Cohort 1 experienced DLT's after 4 weeks, all patients in Cohort 2 will receive cisplatin and PI3K inhibitor GDC-0941, GDC-0941dose not to exceed 260mg.
If 1 patient experiences a DLT in the first cohort, an additional cohort of 3 patients will be treated at the same dose level in cohort 2.
If ≤1 patient has a DLT in 6 (cohort 1 and 2) treated at this same dose, this will be considered a tolerable dose to move to phase II.
|
1PHIbB - Arm B - Cisplatin + GDC -0941 Dose Level -1
If 2 or more patients in 3 or 6 patients (cohort 1 and 2) treated at a given dose 260 mg experience DLT, the dose will be de-escalated to the next lower dose level.
|
2PHII 1 - Arm 1 - Cisplatin Only
n=2 participants at risk
Patients receive cisplatin in Arm I. Patients may crossover to Arm II upon disease progression.
cisplatin:patients received 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.
