Study Endpoints
Primary Endpoints
Maximum Tolerated Dose (MTD)
Baseline up to Week 6

The MTD was defined as the highest dose of PF-03446962 associated with the occurrence of Dose Limiting Toxicities (DLTs) in at most 1 of 6 participants with the next higher dose having at least 2/3 or 2/6 participants experiencing DLTs (that is (i.e.) Maximum Administrated Dose). DLT is defined if the participants meets the following criteria during the first 6 weeks of treatment, possibly attributable to PF-03446962. Neutropenia grade 4 (less than \[\< \])500/cubic millimeter \[mm\^ 3\]) lasting for greater than equal to (\>=) 8 days; Febrile Neutropenia \>= Grade 3; Neutropenic Infection \>= Grade 3; Grade 4 thrombocytopenia (\<25,000/mm\^3); Grade 3 thrombocytopenia (\<50,000/mm\^3) with active bleeding; Grade 3 or higher non-hematological toxicity.

Recommended Phase-2 Dose (RP2D)
Baseline up to 28 days after last dose of study medication

RP2D was determined by a comprehensive assessments based on all the safety data, efficacy data, pharmacokinetics profile and biomarker data using blood and tumor samples.

Secondary Endpoints
Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)
Baseline up to 28 days after last dose
