A Study of Rucaparib in Patients With Platinum-Sensitive, Relapsed, High-Grade Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Cancer (ARIEL2)

The confirmed response rate by RECIST v1.1 is defined as the percentage of patients with a confirmed complete response (CR) or partial response (PR) on subsequent tumor assessment at least 28 days after first response documentation. Complete response (CR) is disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Partial response (PR) is at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum of longest diameter.

Time frame: Assessments every 8 weeks from C1D1 until disease progression, death or withdrawal of consent. After 18 months on study, assessments every 16 weeks. Total follow-up was up to approximately 3 years.

Population: Safety population by HRD subgroups: Consist of all Part 2 patients who received at least one dose of rucaparib.

The primary efficacy endpoint of PFS is calculated as 1+ the number of days from the first dose of study drug to disease progression by RECIST (Response Evaluation Criteria in Solid Tumors), as determined by the investigator or death due to any cause, whichever occurs first. Progression is defined using RECIST v1.1, as at least a 20% increase in the sum of the longest diameter of target lesions, or a measureable increase in a non-target lesion, or the appearance of new lesions.

Time frame: Assessments every 8 weeks from C1D1 until disease progression, death or withdrawal of consent. After 18 months on study, assessments every 16 weeks. Total follow-up was up to approximately 3 years.

Population: Safety population by HRD subgroups: Consists of all Part 1 patients who received at least one dose of rucaparib.

Duration of response (DOR) for any confirmed RECIST CR or PR measured from the date of the first occurrence of a response until the first occurrence of progressive disease (PD) per RECIST. For patients who continued treatment post-progression, the first date of progression was used for the analysis. Any patients with an ongoing response were censored at the date of the last post-baseline scan. Complete response (CR) is disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Partial response (PR) is at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum of longest diameter.

Time frame: Assessments every 8 weeks from C1D1 until disease progression, death or withdrawal of consent. After 18 months on study, assessments every 16 weeks. Total follow-up was up to approximately 3 years.

Population: Efficacy population by HRD subgroups. The overall number of patients analyzed includes only patients with confirmed RECIST CR or PR.

The endpoint of ORR defined as the percentage of patients with a best response of CR or PR using RECIST v 1.1 or a response per Gynecologic Cancer InterGroup cancer antigen 125 (GCIG CA-125) criteria. Complete response (CR) is disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Partial response (PR) is at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum of longest diameter. A response to CA-125 has occurred if there is at least a 50% decrease from baseline: 1. in a sample collected after initiation of study treatment AND 2. that is confirmed in a subsequent sample collected ≥21 days after the prior sample. The absolute value of this confirmatory sample must be ≤110% of the prior sample. The date when the first sample with a 50% decrease from baseline is observed is the date of the CA-125 response.

Time frame: Assessments every 8 weeks from C1D1 until disease progression, death or withdrawal of consent. After 18 months on study, assessments every 16 weeks. Total follow-up was up to approximately 3 years.

Population: Safety population by HRD subgroups: Consist of all Part 1 and Part 2 patients who received at least one dose of rucaparib.

Overall survival (OS) is defined as the number of days from the date of first dose of study drug to the date of death (due to any cause). Patients without a known date of death will be censored on the date the patient was last known to be alive.

Time frame: All patients in Part 2 were followed for survival, subsequent therapy, and secondary malignancy every 12 weeks until death, loss to follow-up, withdrawal of consent from study or study closure, whichever happened first, up to 7 years.

Population: Safety population by HRD subgroups: Consist of all Part 2 patients who received at least one dose of rucaparib.

Progression-Free Survival (PFS) is calculated as 1+ the number of days from the first dose of study drug to disease progression by RECIST, as determined by the investigator or death due to any cause, whichever occurs first. Progression is defined using RECIST v1.1, as at least a 20% increase in the sum of the longest diameter of target lesions, or a measureable increase in a non-target lesion, or the appearance of new lesions.

Time frame: Assessments every 8 weeks from C1D1 until disease progression, death or withdrawal of consent. After 18 months on study, assessments every 16 weeks. Total follow-up was up to approximately 3 years.

Population: Safety population by HRD subgroups: Consist of all Part 2 patients who received at least one dose of rucaparib.

Per protocol, the secondary PK endpoint, trough (Cmin) concentrations of rucaparib were summarized with descriptive statistics overall and by cycle in all patients with at least one PK sample collected. Blood samples for trough level PK analysis of rucaparib were drawn at the following timepoints only: on Day 15 of Cycle 1 and on Day 1 of Cycles 2, 3, and 4. Data for other timepoints is not available.

Time frame: Cycle 1 Day 15 to Cycle 4 Day 1, or approximately 10 weeks

Population: All Part 1 and Part 2 patients with at least one PK sample collected
