Part 1 - PF-06263507 will be administered intravenously in 21-day cycles in cohorts of 2 or more patients starting at a dose of 0.05 mg/kg. Increases in dose will continue until MTD is determined.

Part 2 - Patients with select tumor types will be treated at the MTD or Recommended Phase 2 dose selected in Part 1.

Pfizer CT.gov Call Center

To assess the safety and tolerability at increasing dose levels of PF-06263507 in patients with advanced solid tumors in order to determine the maximum tolerated dose and select the recommended Phase 2 dose.

A Study Of PF-06263507 In Patients With Advanced Solid Tumors

A PHASE 1, DOSE ESCALATION STUDY OF PF-06263507 IN PATIENTS WITH ADVANCED SOLID TUMORS

Pfizer will provide access to individual de-identified participant data and related study documents (e.g. protocol, Statistical Analysis Plan (SAP), Clinical Study Report (CSR)) upon request from qualified researchers, and subject to certain criteria, conditions, and exceptions. Further details on Pfizer's data sharing criteria and process for requesting access can be found at: https://www.pfizer.com/science/clinical_trials/trial_data_and_results/data_requests.

DLT was defined as any of the following adverse events (AEs) occurring in the first cycle of treatment (21 days) which were attributable to PF-06263507: 1) Grade 4 neutropenia lasting \>7 days, 2) Febrile neutropenia, 3) Grade \>=3 neutropenia with infection, 4) Any grade thrombocytopenia associated with clinically significant or life-threatening bleeding, 4) Grade 4 thrombocytopenia, 5) Any grade \>=3 non-hematologic toxicities, 6) A positive cardiac troponin I result, 7) Persisting non-hematologic toxicities resulted in more than 2 weeks delay in receiving the next scheduled cycle. Severity of AEs was graded according to Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Treatment-emergent AEs are events which occurred 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. If the same participant in a given treatment had more than 1 occurrence in the same preferred term event category, only the worst CTCAE grade was reported.

Number of participants with NCI CTCAE (version 4.0) grade 1 to 4 hematological test abnormalities.

Number of participants with NCI CTCAE (version 4.0) grade 1 to 4 chemistry tests abnormalities.

Number of participants with NCI CTCAE (version 4.0) grade 1 to 4 abnormalities in urine protein.

Criteria for potentially clinically important (PCI) change in vital signs included: sitting systolic blood pressure (SBP) of \<90 millimeters of mercury (mm Hg) or change in sitting SBP of \>=30 mm Hg, sitting diastolic blood pressure (DBP) of \<50 mm Hg or change in sitting DBP of \>=20 mm Hg, sitting pulse rate of \<40 or \>120 beats per minute (bpm).

The number of participants with positive anti-PF-06263507 antibody.

Number of participants with best overall response. Complete response (CR)=disappearance of all target lesions. Partial Response (PR)\>=30% decrease in sum of longest dimensions of lesions taking as reference baseline sum longest dimensions. Progressive disease (PD) \>=20% increase in sum of longest dimensions of lesions taking as a reference smallest sum of the longest dimensions since treatment start, or the appearance of \>=1 new lesion. Stable disease (SD)=neither shrinkage for PR or increase for PD taking as reference smallest sum of longest dimensions since treatment start.

Number of particpants with objective response: confirmed CR or confirmed PR according to RECIST. CR was defined as the disappearance of all target lesions. A PR was defined as a ≥30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions. To be assigned a status of PR or CR, changes in tumor measurements in participants with responding tumors had to have been confirmed by repeat studies that were performed ≥ 4 weeks after the criteria for response were first met.

Overall survival was defined as the time from initial dose until death from any cause, and was measured in the intent-to-treat population.
