Limitations and caveats
Study was terminated early and included a small number of subjects, and insufficient data were available to evaluate the clinical activity of the study treatment. Due to low enrollment, some protocol-specified outcome measures were not evaluated.

ListOutcomeTime frameDescription
PrimaryPhase 1: Number of Subjects Reporting Hematologic and/or Non-hematologic Dose-limiting Toxicity (DLT)Subjects followed for DLTs for 21 days following the first dose of CRS-207 (treatment Cycle 1 for CRS-207).
Count of subjects in the Phase 1 cohorts who reported a hematologic and/or non-hematologic DLT. Non-hematological DLTs are defined as follows, excluding the safety events specified for exemption in Section 5.3.1 of the study protocol: * any treatment-emergent adverse event (TEAE) not attributable to disease or disease-related processes that occurs during the DLT observation period (Cycle 1) and is Grade 3 or higher according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v4; * any use of systemic steroids; and/or * a study drug dose interruption lasting ≥ 7 days for an adverse event with an unclear relationship to study drug. Hematological DLTs are defined as: * Grade 4 neutropenia lasting \>7 days; * Grade ≥3 febrile neutropenia; * Grade 4 anemia; * Grade 4 thrombocytopenia or ≥ Grade 3 thrombocytopenia lasting \>7 days or associated with bleeding; and/or * Dose delay \>7 days secondary to myelosuppression.
PrimaryPhase 1: Adverse Events (AEs) by CTCAE Grade 3 or HigherSubjects followed from the start of study treatment until 30 days following the final dose of study drug, an average of 3 months.Count of subjects in the Phase 1 cohorts with incidences of CTCAE Grade 3 or higher AEs.
PrimaryPhase 2: Adverse Events (AEs)Subjects followed from the start of study treatment until 30 days following the final dose of study drug, an average of 2 months.Count of subjects in the Phase 2 cohorts with incidences of AEs.
PrimaryPhase 2: Objective Response Rate (ORR)
BOR was assessed from the first dose of study treatment until documented disease progression, initiation of a new cancer treatment, death, or study termination, whichever comes first, assessed up to 20 weeks.
ORR was evaluated for Phase 2 subjects based upon the best overall response (BOR) for individual study subjects. BOR was determined by the highest post-baseline qualitative response value for each assessed subject as measured by modified response evaluation criteria in solid tumors (mRECIST) and given the following hierarchy of overall response results: complete response (CR) \> partial response (PR) \> stable disease (SD) \> progressive disease (PD) \> not evaluable (NE). The protocol-specified ORR was defined as the percentage of evaluable subjects with a BOR of CR or PR; however, this percentage was not calculated per the final study Statistical Analysis Plan (SAP). Therefore, the number of evaluable subjects with BOR mRECIST values of CR, PR, SD, PD, and NE are provided for this outcome measure.
PrimaryPhase 2: Progression Free Survival (PFS)
Subjects followed for disease progression from first dose of study treatment until 30 days after last dose of study treatment or initiation of new cancer treatment, whichever comes first, assessed up to 20 weeks.
Number of weeks from the date of first dose of study treatment to the first date of objectively determined progressive disease (PD) or death from any cause, estimated using Kaplan-Meier (KM) methods with 95% confidence intervals (CIs). PD is determined by mRECIST.
SecondaryPhase 1: Objective Response Rate (ORR) by mRECIST
BOR was assessed from the first dose of study treatment until documented disease progression, starting of a new cancer treatment, death, or study termination, whichever is earlier, assessed up to 100 weeks.
ORR was evaluated for Phase 1 subjects based upon the best overall response (BOR) for individual study subjects. BOR was determined by the highest post-baseline qualitative response value for each assessed subject as measured by modified response evaluation criteria in solid tumors (mRECIST), RECIST v1.1, and GCIG CA-125 criteria and given the following hierarchy of overall response results: complete response (CR) \> partial response (PR) \> stable disease (SD) \> progressive disease (PD) \> not evaluable (NE). The protocol-specified ORR was defined as the percentage of evaluable subjects with a BOR of CR or PR; however, this percentage was not calculated per the final study Statistical Analysis Plan (SAP). Therefore, the number of evaluable subjects with BOR mRECIST values of CR, PR, SD, PD, and NE are provided for this outcome measure.
SecondaryPhase 1: Progression Free Survival (PFS)
Subjects followed for disease progression from first dose of study treatment until 30 days after last dose of study treatment or initiation of new cancer treatment, whichever comes first, assessed up to 100 weeks
Number of weeks from the date of first dose of study treatment to the first date of objectively determined progressive disease (PD) or death due to any cause, estimated using Kaplan-Meier (KM) methods with 95% confidence intervals (CIs). PD is determined by mRECIST, RECIST v1.1, and GCIG CA-125.
SecondaryDisease Control Rate (DCR)
BOR was assessed from the first dose of study treatment until documented disease progression, starting of a new cancer treatment, death, or study termination, whichever comes first, assessed up to 100 weeks.
The protocol-specified DCR was defined as the percentage of evaluable subjects with a BOR of CR or PR, or SD as determined by mRECIST, RECIST v1.1, and GCIG CA-125 criteria.
SecondaryDuration of Response (DOR)Subjects followed for disease progression from date of CR or PR designation until documented disease progression or study termination, whichever comes first, assessed up to 100 weeks.Number of weeks from date of CR or PR designation until PD designation, as determined by mRECIST, RECIST v1.1 and GCIG CA-125 criteria.
SecondaryOverall Survival (OS)OS was assessed from the first dose of study treatment until death or study termination, whichever comes first, assessed up to 100 weeks.
Number of weeks from the date of first dose of study treatment to the date of death from any cause, estimated using KM methods with 95% CIs for subjects in the SAF. Subjects without documentation of death at the time of analysis were censored as of the date the subject was last known to be alive. For subjects lost to follow up, the last visit or last contact date where the subject is documented to be alive will be used to estimate last known date alive.
