What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With First Cycle Dose Limiting Toxicities (DLTs)

    Any DLT event in Cycle 1: (1) Grade 4 neutropenia lasting more than 7 days; (2) Febrile neutropenia; (3) Grade >=3 neutropenic infection; (4) Grade >=3 thrombocytopenia with bleeding; (5) Grade 4 thrombocytopenia lasting more than 7 days; (6) Grade >=3 non-hematologic toxicity; (7) Failure to deliver at least 80% of the planned doses due to toxicities attributable to PF-04449913

    Measured: Baseline up to end of Cycle 1 (Study Day 28)

Secondary outcomes (21)
  1. Percentage of Participants With Treatment-emergent Adverse Events (AEs), by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) (Version 4.0) Grade

    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 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 one occurrence in the same preferred term event category, only the worst CTCAE grade was reported. Grades as per NCI CTCAE, v4.0 were classified as: Grade 1- mild, Grade 2- moderate, Grade 3- severe, Grade 4- life threatening, and Grade 5- death.

    Measured: Baseline up to 28 days post last dose of study medication (maximum duration: 14 cycles [each cycle of 28 days])

  2. Percentage of Participants With Treatment-related AEs, by NCI CTCAE (Version 4.0) Grade

    An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. Treatment-related AEs are events that were assessed by the investigator as related to study medication. If the same participant in a given treatment had more than one occurrence in the same preferred term event category, only the worst CTCAE grade was reported. Grades as per NCI CTCAE, v4.0 were classified as: Grade 1- mild, Grade 2- moderate, Grade 3- severe, Grade 4- life threatening, and Grade 5- death.

    Measured: Baseline up to 28 days post last dose of study medication (maximum duration: 14 cycles [each cycle of 28 days])

  3. Hedgehog Biomarker Modulation: Relative GLI1 Gene Expression (Ratio) to Baseline for Normal Skin on Cycle 1/Day 15

    Ribonucleic acid (RNA) was extracted from skin samples and complementary deoxyribonucleic acid (cDNA) was prepared. Gene expression was measured using custom Taqman low density array (TLDA) cards run on the Applied Biosystems ViiATM 7 system.

    Measured: Pre dose, 1, 2, 4, 10, 24, 48, 72 and 96 hours post dose on Cycle 1/Day 25

  11. Apparent Oral Clearance (CL/F) on Cycle 1/Day 25

    Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes.

    Measured: Pre dose, 1, 2, 4, 10, 24, 48, 72 and 96 hours post dose on Cycle 1/Day 25

  12. Apparent Volume of Distribution (Vz/F) on Cycle 1/Day 25

    Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug.

    Measured: Pre dose, 1, 2, 4, 10, 24, 48, 72 and 96 hours post dose on Cycle 1/Day 25

  13. Accumulation Ratio (Rac) on Cycle 1/Day 25

    Accumulation ratio was calculated as AUCtau at steady state (Cycle 1/Day 25)/AUCtau on Study Day 1

    Measured: Pre dose, 1, 2, 4, 6, 10 and 24 hours post dose on Cycle 1/Day 1, and pre dose, 1, 2, 4, 10, 24, 48, 72 and 96 hours post dose on Cycle 1/Day 25

  15. Number of Participants With Increase From Baseline in Corrected QT Using Fridericia's Formula (QTcF) Interval

    Triplicate 12-lead electrocardiogram (ECG) measurements (each recording separated by approximately 2 minutes) were performed and average was calculated. The time from electrocardiogram Q wave to the end of the T wave corresponding to electrical systole (QT) was corrected for heart rate (QTc). QTc using Fridericia's formula (QTcF) was calculated. Participants with maximum increase from baseline of less than (<) 30 millisecond (msec), 30 to <60 msec and >=60 msec were summarized.

    Measured: Baseline up to Cycle 14 (each cycle 28 days)

  16. Number of Participants With Decrease From Baseline in QTcF Interval

    Triplicate 12-lead ECG measurements (each recording separated by approximately 2 minutes) were performed and average was calculated. QTcF was calculated. Participants with maximum decrease from baseline of <30 msec, 30 to <60 msec and >=60 msec were summarized.

    Measured: Baseline up to Cycle 14 (each cycle 28 days)

  17. Number of Participants With Post-baseline QTcF Interval Greater Than or Equal to 500 Msec

    Triplicate 12-lead ECG measurements (each recording separated by approximately 2 minutes) were performed and average was calculated. Participants with post-baseline absolute QTcF values >=500 msec were summarized.

    Measured: Baseline up to Cycle 14 (each cycle 28 days)

  18. Percentage of Participants With Objective Response

    Percentage of participants with objective response based on assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. Confirmed responses were those that persisted on repeat imaging study at least 4 weeks after initial documentation of response. CR was defined as complete disappearance of all target lesions with the exception of nodal disease. PR was defined as >=30% decrease under baseline of the sum of diameters of all target measurable lesions.

    Measured: Baseline up to Cycle 14 (each cycle 28 days)

  19. Progression-Free Survival (PFS)

    Time from Cycle 1/Day 1 to first documentation of disease progression or to death due to any cause, whichever occurred first. Progression was defined using RECIST 1.1 as 20% increase in the sum of diameters of target measurable lesions above the smallest sum observed, with a minimum absolute increase of 5 mm. PFS (days) was calculated as (first event date minus the date of first dose of study medication plus 1).

    Measured: Baseline up to Cycle 14 (each cycle 28 days)

  20. Time to Progression (TTP)

    Time from Cycle 1/Day 1 to first documentation of disease progression. Progression was defined using RECIST 1.1 as 20% increase in the sum of diameters of target measurable lesions above the smallest sum observed, with a minimum absolute increase of 5 mm. TTP (days) was calculated as (first event date minus the date of first dose of study medication plus 1).

    Measured: Baseline up to Cycle 14 (each cycle 28 days)

  21. Duration of Response (DR)

    Duration from date of first documentation of objective response to date of first documentation of disease progression or death. Progression was defined using RECIST 1.1 as 20% increase in the sum of diameters of target measurable lesions above the smallest sum observed, with a minimum absolute increase of 5 mm. DR was calculated as (the date of the first documentation of objective tumor progression or death due to cancer minus the date of the first objective response that was subsequently confirmed plus 1).

    Measured: Baseline up to Cycle 14 (each cycle 28 days)
