A Dose Finding Study Of A New Medication, PF-00337210 That Will Possibly Decrease Blood Supply To Tumors

Phase I, Open-Label, Multi-Center, Accelerated Dose Escalation Study Of The Anti-Angiogenesis Agent PF-00337210 In Patients With Advanced Solid Tumors

This study will test a new cancer medication to determine if this medication will block blood supply to a tumor and decrease growth of a tumor. This study will also define the safety profile and define the safest dose of this new medication for people who have cancer.

DLTs: blood pressure of 180/110 mmHg or higher for 3 readings over 3 hours regardless of use of anti-hypertensive drugs or >160/100 mmHg for 3 readings over 3 days on maximum anti-hypertensive drugs; afebrile Grade 4 neutropenia >=7 days or >= Grade 3 neutropenia associated with fever (1 reading of oral temperature >38.5 degree C or 3 readings of oral temperature >38.0 degree C in 24-hour period); Grade 4 thrombocytopenia; hemoptysis of >1/2 teaspoon of bright red blood per day; proteinuria of >=2 grams/24 hours; inability to resume PF-00337210 dosing at current dose level within 14 days of stopping due to treatment-related toxicity; >=Grade 3 nonhematological toxicities (except alopecia and blood pressure/hypertension); Grade 3 nonhematological toxicities that could be controlled to Grade 2 or less with appropriate treatment were not considered dose limiting.	Day 28
Maximum Administered Dose (MAD)	MAD: dose level at which 2 or more out of 6 participants experienced DLT during Cycle 1. DLTs: blood pressure of 180/110 mmHg or higher for 3 readings over 3 hours regardless of use of anti-hypertensive drugs or >160/100 mmHg for 3 readings over 3 days on maximum anti-hypertensive drugs; afebrile Grade 4 neutropenia >=7 days or >= Grade 3 neutropenia associated with fever (1 reading of oral temperature >38.5 degree C or 3 readings of oral temperature >38.0 degree C in 24-hour period); Grade 4 thrombocytopenia; hemoptysis of >1/2 teaspoon of bright red blood per day; proteinuria of >=2 grams/24 hours; inability to resume PF-00337210 dosing at current dose level within 14 days of stopping due to treatment-related toxicity; >=Grade 3 nonhematological toxicities (except alopecia and blood pressure/hypertension); Grade 3 nonhematological toxicities that could be controlled to Grade 2 or less with appropriate treatment were not considered dose limiting.	Day 28
Recommended Phase-2 Dose (RP2D)	RP2D was determined based on the safety profile and pharmacodynamic findings. The twice daily dosing was preferred over once daily dosing for RP2D, as per investigator's discretion, due to more consistent changes in pharmacodynamic markers and greater clinical benefit observed in twice daily dosing.	Day 28
