A Study Of PF-05212384 In Combination With Other Anti-Tumor Agents and in Combination With Cisplatin in Patients With Triple Negative Breast Cancer in an Expansion Arm (TNBC)

A PHASE 1B OPEN-LABEL THREE-ARM MULTI-CENTER STUDY TO ASSESS THE SAFETY AND TOLERABILITY OF PF-05212384 (PI3K/MTOR INHIBITOR) IN COMBINATION WITH OTHER ANTI-TUMOR AGENTS

This study will evaluate PF-05212384 (gedatolisib) PI3K/mTOR inhibitor)) in combination with either docetaxel, cisplatin or dacomitinib in select advanced solid tumors. The study will assess the safety, pharmacokinetics and pharmacodynamics of these combinations in patients with advanced cancer in order to determine the maximum tolerated dose in each combination. The cisplatin combination expansion portion will evaluate the anti tumor activity of PF 05212384 plus cisplatin in patients with TNBC in 2 separate Arms (Arm 1 and Arm 2).

Number of Participants With Maximum Increase From Baseline in Corrected QT (QTc) Interval	Triplicate 12-lead ECG measurements (each recording separated by approximately 2 minutes) were performed and average was calculated. The time corresponding to beginning of depolarization to repolarization of the ventricles (QT interval) was adjusted for RR interval using QT and RR from each ECG by Fridericia's formula (QTcF = QT divided by cube root of RR) and by Bazette's formula (QTcB = QT divided by square root of RR).

Baseline up to 18 months.

SD was defined as not qualifying for CR, PR, Progressive Disease (PD).	Baseline up to 18 months.
Duration of Response - Arm B Expansion	Duration of response was calculated from first date of partial response (PR) or complete response (CR) to the date of progression or death due to any cause. In the event of no progression or death, the last tumor assessment date without progression was used in this calculation.	Baseline up to 18 months.
Progression Free Survival - Arm B Expansion	Progression free survival (PFS) defined as the time from first dose of study treatment to date of first documentation of progression or death due to any cause, whichever occurs first. PFS was calculated as first event date minus the date of first dose of study medication plus 1 . Tumor progression was determined from oncologic assessment data (where data meet the criteria for progressive disease [PD]), or from adverse event (AE) data (where the outcome was "Death").	Baseline up to 18 months.

Most questions used 4 point scale (1 'Not at all' to 4 'Very much'; 2 questions used 7-point scale (1 'very poor' to 7 'Excellent'). Scores averaged, transformed to 0-100 scale; higher score=better level of functioning or greater degree of symptoms.	Baseline, Day 1 and Day 8 of Cycles 1 and 2, Day 1 of Cycles 3 to 16.
