The log ratio of tumor size at Cycle 2 to tumor size at baseline is calculated for each participant, where the tumor size is the sum of the target lesion measurements at each assessment.
The percentage of participants who achieved a best response of either CR or PR, as determined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 guidelines. CR was defined as the disappearance of all target and non-target lesions and any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 millimeter (mm) and normalization of tumor marker level of non-target lesions. PR was defined as at least a 30% decrease in sum of longest diameter of target lesions and for prostate cancer PR was defined as a ≥50% decrease in baseline prostate-specific antigen (PSA) value that was confirmed with a second value ≥3 weeks later. Progressive Disease (PD) was defined as at least 20% increase in sum of longest diameter of target lesions and minimum 5 mm increase over nadir. Percentage is calculated as a total number of participants with CR or PR divided by the total number of participants treated multiplied by 100.
The overall response is complete response (CR) + partial response (PR) as classified by the investigators according to the Response Evaluation Criteria In Solid Tumors (RECIST) guidelines. CR is the disappearance of all target and non-target lesions; PR is a ≥30% decrease in sum of longest diameter of target lesions. The overall response rate is calculated as a total number of participants with CR or PR, then divided by the total number of participants treated, then multiplied by 100.
Clinical benefit rate is complete response (CR) + partial response (PR) + stable disease (SD) as classified by the investigator according to the Response Evaluation Criteria In Solid Tumors (RECIST) guidelines. CR is the disappearance of all target and non-target lesions; PR is a ≥30% decrease in sum of longest diameter of target lesions. SD is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease. Clinical benefit rate is calculated as a total number of participants with CR or PR or SD divided by the total number of participants treated, then multiplied by 100.
The recommended dose and schedule for Phase 2 studies is defined as the maximum tolerated dose (MTD). MTD is defined as the dose level at which no more than 2 dose limiting toxicities (DLTs), no more than 3 dose reductions (DR) or dose omissions (DO) and no more than 1 DLT plus 2 DR/DO occurred. DLT is defined as an adverse event (AE) occurring in Cycle 1 with the following criteria according to the National Cancer Institute's (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v3.0: Any ≥Grade 3 nonhematological toxicity (except nausea/vomiting or diarrhea controlled with treatment or fatigue); ≥Grade 4 thrombocytopenia, or Grade 3 thrombocytopenia with bleeding; Grade 4 hematological toxicity of \>5 days duration, excluding thrombocytopenia; febrile neutropenia.
Recommended Phase 2 dose was determined by the maximum tolerated dose (MTD). The MTD was defined as the dose that caused \<1/3 of all participants treated with the study drug to experience a dose-limiting toxicity (DLT). A DLT was defined as an adverse event (AE) occurring during Cycle 1 that fulfilled 1 of the following criteria: Any Common Terminology Criteria for Adverse Events (CTCAE), version (v) 3.0 Grade ≥3 nonhematological toxicity possibly or likely related to the study drug (except for nausea/vomiting/diarrhea without maximal symptomatic/prophylactic treatment); any CTCAE v 3.0 Grade ≥3 thrombocytopenia with bleeding; any CTCAE v3.0 Grade 4 hematological toxicity of \>5 days duration; any febrile neutropenia.
