Outcomes
Primary Outcomes
Number of Participants With Dose Limiting Toxicities (DLTs) [Part 1]
Time Frame: Baseline to Day 28
DLTs: Any of the following adverse events (AE) occurring in the first cycle of treatment, unless there is a clear alternative explanation. Hematologic: Grade (Gr) 4 neutropenia lasting \>=5 days; febrile neutropenia; Gr\>=3 neutropenic with infection; Gr\>=3 thrombocytopenia with bleeding; Gr 4 thrombocytopenia. Non-Hematologic: Any toxicity attributable to PF-06840003 that resulted in administration of less than 80% of the planned doses during Cycle 1; Gr 4 non-hematologic AE; Gr 3 AE lasting \>7 days despite optimal supportive care; Gr 3 central nervous system (CNS) AE regardless of duration; Gr 3 QTc prolongation (QTc \>500 milliseconds) (a DLT only if persisting after correction of any reversible causes); Concurrent aspartate aminotransferase (AST) or alanine aminotransferase (ALT) \>3\*upper limit of normal (ULN) and total bilirubin \>2\*ULN.
Number of Participants With Treatment-Emergent Adverse Events (TEAEs) [Part 1]
Time Frame: Baseline up to 1 year
An AE was any untoward medical occurrence in a clinical investigation patient administered a product or medical device; the event needed not necessarily have a causal relationship with the treatment or usage. TEAEs were those with initial onset or increasing in severity after the first dose of study treatment.
Number of Participants With TEAEs by Severity (as Graded by National Cancer Institute [NCI] Common Terminology Criteria for Adverse Event [CTCAE] Version 4.03) [Part 1]
Time Frame: Baseline up to 1 year
Treatment-emergent AEs were those with initial onset or increasing in severity after the first dose of study treatment. AEs were graded by the investigator according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03: Grade 3: severe AE; Grade 4: life-threatening consequences, urgent intervention indicated; Grade 5: death related to AE.
