What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Dose-limiting Toxicities (DLT)
Time Frame: Baseline up to Cycle 2 Day 1 (22 days)
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.
Baseline up to Cycle 2 Day 1 (22 days)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame

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.

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.
