GSK Limits Second-Line Maintenance Use Of Its Ovarian Cancer Drug To Some Populations

  • GSK plc GSK would restrict the second-line maintenance indication for Zejula to only patients with harmful, or suspected to be harmful, inherited BRCA mutations at the request of the FDA.
  • The decision follows an FDA review of the final overall survival (OS) analysis of the ENGOT-OV16/NOVA phase 3 trial, which served as the basis for the approval of the second-line maintenance indication.

  • In the final OS results from the NOVA trial, the secondary endpoint of OS demonstrated a hazard ratio (HR) of 1.06 in the non-gBRCAmut cohort. 
  • Zejula's U.S. indication for earlier lines of treatment as a first maintenance option in adults in some types of advanced ovarian, fallopian tube, or primary peritoneal cancer patients responding to chemotherapy remains unchanged, GSK said.
  • Price Action: GSK shares are down 4.33% at $32.02 during the premarket session on the last check Friday.
