|Condition or disease||Intervention/treatment||Phase|
|Advanced or Inoperable Gastric Cancer||Drug: pamiparib Drug: Placebo||Phase 2|
This is a double-blind, placebo controlled, randomized multicenter global phase 2 study comparing the efficacy and safety of single agent poly (ADP-ribose) polymerase (PARP) inhibitor BGB-290 to placebo as maintenance therapy in participants with advanced gastric cancer who have responded to first line platinum based chemotherapy. Participants are randomized 1:1 to BGB-290 (Arm A) or placebo (Arm B). Randomization will be stratified by geography, biomarker status, and ECOG performance status.
Participants will undergo tumor assessments at screening and then every 8 weeks, or as clinically indicated. Administration of BGB-290 or placebo will continue until disease progression, unacceptable toxicity, death, or another discontinuation criterion is met.
After end of treatment, long-term follow-up assessments include tumor imaging every 8 weeks for those participants without disease progression, survival status, and new anticancer therapy.

- Progression free survival [ Time Frame: From randomization to the date of first documentation of disease progression or death due to any cause, whichever occurs first up to 5 years ]The primary objective of this study is to compare progression free survival between treatment groups (BGB-290 versus placebo) as determined by blinded independent central review.
- Overall survival between treatment groups (BGB-290 versus placebo) [ Time Frame: From time of randomization until date of death due to any cause assessed, up to 2.5 years ]
- Progression free survival between treatment groups determined by investigator assessment [ Time Frame: From randomization to the date of first documentation of disease progression or death due to any cause, whichever occurs first, up to 2.5 years ]
- Progression free survival on subsequent treatment (PFS2) [ Time Frame: From the time of randomization to second disease progression, or death from any cause, whichever is first, up to 2.5 years ]
- Time to second subsequent treatment [ Time Frame: From the time from randomization until the second subsequent anti-cancer therapy or death after next-line therapy, up to 2.5 years ]
- Objective response rate by investigator assessment [ Time Frame: From randomization to first documentation of disease progression assessed up to 2.5 years ]
- Duration of response by investigator assessment [ Time Frame: The time from the first documented confirmed response of CR or PR to PD or death due to any cause, whichever occurs first, up to 2.5 years ]
- Time to response by investigator assessment [ Time Frame: Defined as the time from randomization to the first documented confirmed response of CR or PR assessed up to 2.5 years ]
- Incidence, nature and severity of adverse events between treatment groups [ Time Frame: From time of randomization to approximately 30 days after end of treatment ]
