Outcomes Module

Primary Outcomes

Measure	Description	Time Frame
Number of Participants With Treatment-Emergent Adverse Events (AEs) or Serious Adverse Events (SAEs)	An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to 28 days after last dose that were absent before treatment or that worsened relative to pretreatment state.	Baseline up to 28 days after the last dose
Number of Participants With Dose Limiting Toxicities (DLTs)	DLT was classified as per common terminology criteria for adverse events (CTCAE) version 4.0 and defined as any of the following events occurring after first dose of study medication and considered at least possibly-related to study medication. Hematological: grade 4 neutropenia (absolute neutrophil count [ANC] <500 cells per cubic millimeter [cells/mm^3]) for 1 week or greater, febrile neutropenia (fever >=38.5 degree celsius with ANC <1000/mm^3), grade 3 (50,000 cells/mm^3) and grade 4 (<25,000 cells/mm^3) thrombocytopenia; Non-Hematologic: grade 3 or 4 nausea, vomiting, or diarrhea and any clinically significant grade 3 or greater non-hematologic toxicity, despite the use of adequate/maximal medical intervention and/or prophylaxis, and any persistent, intolerable PF-04691502 related toxicity which delayed retreatment for >14 days.	Baseline up to Cycle 1 Day 21
Recommended Phase-2 Dose (RP2D)	RP2D was determined based on the safety profile and pharmacodynamic findings, as per investigator's discretion.	Baseline up to Cycle 1 Day 21

Secondary Outcomes

Measure	Description	Time Frame
Maximum Observed Plasma Concentration (Cmax)	The pharmacokinetics (PK) of PF-04691502 was assessed following a single oral dose administration in lead-in-dose period (single dose PK) and repeated oral dose administration for 21 days in Cycle 1 (multiple dose PK).	Pre-dose, 30 minutes, 1, 2, 4, 6, 8, 24, 48, 72, 96 hours post-dose in Lead-in period; pre-dose, 30 minutes, 1, 2, 4, 6, 8, 24 hours post-dose on Cycle 1 Day 21 (C1D21)

Exclusion Criteria:

Patients with known active brain metastases. Patients with previously diagnosed brain metastases are eligible if they have completed their CNS treatment and have recovered from the acute effects of radiation therapy or surgery prior to the start of study medication, have discontinued corticosteroid treatment for these metastases for at least 4 weeks and are neurologically stable
Chemotherapy, radiotherapy (other than palliative radiotherapy to lesions that will not be followed for tumor assessment on this study, ie, non target lesions), biological or investigational agents within 2 weeks of Baseline disease assessments
Any surgery (not including minor procedures such as lymph node biopsy) within 4 weeks of Baseline disease assessments; or not fully recovered from any side effects of previous procedures
Prior therapy with an agent that is known or proposed to be active by action on PI3K and/or mTOR
Prior high-dose chemotherapy requiring hematopoetic stem cell transplantation within 12 months of study treatment start
Uncontrolled or significant cardiovascular disease:

A myocardial infarction within 12 months Uncontrolled angina within 6 months Congestive heart failure within 6 months. Diagnosed or suspected congenital long QT syndrome. Any history of ventricular arrhythmias (such as ventricular tachycardia, ventricular fibrillation, or Torsades de pointes). Any history of second or third degree heart block (may be eligible if currently have a pacemaker) Heart rate <50/minute on pre-entry electrocardiogram Uncontrolled hypertension.

Current use or anticipated need for food or drugs that are known potent CYP3A4 inhibitors or inducers
Current use or anticipated need for food or drugs that are known potent CYP1A2 inhibitors or inducers
Concurrent administration of herbal preparations
Breast feeding: No studies have been conducted in humans to assess the impact of PF-04691502 on milk production, its presence in breast milk and its effects on the breast-fed child. Because drugs are commonly excreted in human milk and because of the potential for serious adverse reactions in nursing infants, lactating female patients are excluded from this study.
Any clinically significant gastrointestinal abnormalities, which may impair intake, transit or absorption of the study drug, such as the inability to take oral medication in tablet form and malabsorption syndrome.
Any mental disorder that would limit the understanding or rendering of informed consent and/or compromise compliance with the requirements of this protocol
