| Number of Participants With Objective Response, as Assessed by the Investigator Per Response Evaluation Criteria in Solid Tumors (RECIST) Version (v)1.1 (Phase 2) | From the first dose of study drug until the date of documented response to treatment, assessed up to 2 years | Objective response was defined as a documented and confirmed best overall response of complete response (CR) or partial response (PR) as assessed by the investigator. CR: Disappearance of all target and non-target lesions; any pathological lymph nodes (whether target or nontarget) must have reduction in short axis to \<10 millimeters (mm); and normalization of tumor marker level. PR: At least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD. |

| Duration of Response (DOR) (Phase 2) | From the date of first best response to disease progression or death, whichever occurs first, assessed up to 2 years | Duration of response was measured from the date that best response (CR or PR) was first recorded until the first date that disease progression was documented per RECIST v1.1. CR: Disappearance of all target and non-target lesions; any pathological lymph nodes (whether target or nontarget) must have reduction in short axis to \<10 mm; and normalization of tumor marker level. PR: At least a 30% decrease in the sum of the LD of target lesions, taking as reference the baseline sum LD. Progressive disease: At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum on study (this included the baseline sum if that was the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions and/or unequivocal progression of existing nontarget lesions was also considered progression. |

Progressive disease: At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum on study (this included the baseline sum if that was the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.

Pre-assignment details
The study was planned to be conducted in 2 phases: Phase 1b and Phase 2. Enrollment was terminated before Phase 1b was complete, due to Sponsor's decision to discontinue development of the combination of rucaparib and sacituzumab govitecan. Hence, Phase 2 portion of the study was not conducted.

Outcome results
Number of Participants With Objective Response, as Assessed by the Investigator Per Response Evaluation Criteria in Solid Tumors (RECIST) Version (v)1.1 (Phase 2)
Objective response was defined as a documented and confirmed best overall response of complete response (CR) or partial response (PR) as assessed by the investigator. CR: Disappearance of all target and non-target lesions; any pathological lymph nodes (whether target or nontarget) must have reduction in short axis to \<10 millimeters (mm); and normalization of tumor marker level. PR: At least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD.
Time frame: From the first dose of study drug until the date of documented response to treatment, assessed up to 2 years
Population: Due to Sponsor's decision to discontinue development of the combination of rucaparib and sacituzumab govitecan, the study was terminated before Phase 1b was complete, and Phase 2 portion of the study was not conducted. Hence, the data for this outcome measure could not be collected and analyzed.
Duration of Response (DOR) (Phase 2)
Duration of response was measured from the date that best response (CR or PR) was first recorded until the first date that disease progression was documented per RECIST v1.1. CR: Disappearance of all target and non-target lesions; any pathological lymph nodes (whether target or nontarget) must have reduction in short axis to \<10 mm; and normalization of tumor marker level. PR: At least a 30% decrease in the sum of the LD of target lesions, taking as reference the baseline sum LD. Progressive disease: At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum on study (this included the baseline sum if that was the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions and/or unequivocal progression of existing nontarget lesions was also considered progression.
Time frame: From the date of first best response to disease progression or death, whichever occurs first, assessed up to 2 years
Population: Due to Sponsor's decision to discontinue development of the combination of rucaparib and sacituzumab govitecan, the study was terminated before Phase 1b was complete, and Phase 2 portion of the study was not conducted. Hence, the data for this outcome measure could not be collected and analyzed.
Number of Participants With Objective Response, as Assessed by the Investigator Per RECIST v1.1 (Phase 1b)
Objective response was defined as a documented and confirmed best overall response of CR or PR as assessed by the investigator. CR: Disappearance of all target and non-target lesions; any pathological lymph nodes (whether target or nontarget) must have reduction in short axis to \<10 mm; and normalization of tumor marker level. PR: At least a 30% decrease in the sum of the LD of target lesions, taking as reference the baseline sum LD.
Time frame: From the first dose of study drug until the date of documented response to treatment, assessed up to 2 years
Population: Efficacy population included all participants who had received at least 1 dose of rucaparib or the second study drug and who had measurable disease per RECIST v1.1 at baseline.

Progression-free Survival (PFS) (Phase 2)
PFS was measured as the 1+ the number of days from the first dose of study drug to documented radiographic progression, according to RECIST v1.1, as determined by the investigator, or death due to any cause, whichever occurred first. Progressive disease: At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum on study (this included the baseline sum if that was the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions and/or unequivocal progression of existing nontarget lesions was also considered progression.
