BOR:best response recorded from treatment start until disease progression as per Response Evaluation Criteria in Solid Tumors (RECIST). Complete Response: disappearance of all lesions. Partial Response (PR):greater than or equal to (\>=)30% decrease in sum of longest diameters (SLDs) of target lesions (TLs) taking as reference baseline SLD. Progressive disease (PD):\>=20% increase in SLD of TLs taking as reference smallest SLD since treatment start, or appearance of \>=1 new lesion. Stable disease:neither shrinkage for PR nor increase for PD taking as reference smallest SLD since treatment start.

The highest dose at which less than (\<) 33 percent (%) of participants experienced dose-limiting toxicities (DLT) was to be designated as the maximum tolerated dose (MTD) as well as the RP2D. DLT was defined as any of the following events: Grade 3/4 (severe or life-threatening/ disabling adverse event \[AE\]) nausea, vomiting, or diarrhea (despite the use of adequate/maximal medical intervention and/or prophylaxis); Grade greater than or equal to (\>=) 3 (severe or life-threatening/disabling AE or death related to AE) non-hematological toxicity; delayed (which delayed scheduled treatment for \>14 days) recovery from toxicity related to treatment with PF-00299804; Grade 4 neutropenia (absolute neutrophil count \[ANC\] \<500 cells per cubic millimeter \[cells/mm\^3\] for 5 or more consecutive days or febrile neutropenia \[fever \>=38.5 degrees Celsius with ANC \<1000 cells/mm\^3\]); and Grade 4 thrombocytopenia (\<25,000 cells/mm\^3) or bleeding which required platelet transfusion.

PFS4m was defined as percent chance of being event free (event defined as progressive disease \[PD\] or death due to any cause, whichever occurred first) at 4 months. Progression was defined using Response Evaluation Criteria in Solid Tumors (RECIST), as at least 20 percent (%) increase in the sum of longest dimensions (LD) of target lesions, taking as reference the smallest sum of LD recorded since the treatment started and/or unequivocal progression of existing non-target lesions and/or appearance of 1 or more new lesions.
