Brief Summary:
This study will enroll participants with previously-treated advanced or inoperable gastric cancer who have responded to first line platinum therapy into two treatment arms. In Arm A participants will receive BGB-290; in Arm B participants will receive placebo. The purpose of this study is to show that BGB-290 (versus placebo) will improve progression-free survival (PFS) in participants with advanced or inoperable gastric cancer.

Condition or disease Intervention/treatment Phase
Advanced or Inoperable Gastric Cancer Drug: pamiparib Drug: Placebo Phase 2

Detailed Description:

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.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. 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.


Secondary Outcome Measures :
  1. 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 ]
  2. 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 ]
  3. 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 ]
  4. 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 ]
  5. Objective response rate by investigator assessment [ Time Frame: From randomization to first documentation of disease progression assessed up to 2.5 years ]
  6. 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 ]
  7. 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 ]
  8. Incidence, nature and severity of adverse events between treatment groups [ Time Frame: From time of randomization to approximately 30 days after end of treatment ]
