Pharmanovia, the global specialty pharmaceutical company, confirms the presentation, by its partner IMPACT Therapeutics, of updated progression-free survival (PFS) results from the Phase 3 FLAMES study of senaparib at the ESMO Congress 2026 in Madrid: Poster 1260P, ‘Updated progression-free survival (PFS) results from the FLAMES study: First-line maintenance senaparib in patients with newly diagnosed advanced ovarian cancer (aOC)’, presented on Monday 26th October at 12:00 CET, by Xiaohua Wu (Shanghai, China).
FLAMES (NCT04169997) is a randomised, double-blind, placebo-controlled Phase 3 study in patients with newly diagnosed advanced ovarian cancer responding to first-line platinum-based chemotherapy, irrespective of BRCA mutation status. Patients were randomised 2:1 to senaparib or placebo.
At the updated data cut-off (1 September 2025; median follow-up 48.5 months), as presented at ESMO 2026:
Median PFS assessed by blinded independent central review was 38.7 months (95% CI 28.0-not estimable) with senaparib versus 13.6 months (95% CI 10.9-16.6) with placebo (HR 0.47; 95% CI 0.36-0.62; p<0.0001). A PFS benefit was observed in both the BRCA-mutated (median PFS 49.8 months; HR 0.41) and BRCA wild-type (median PFS 33.3 months; HR 0.49) subgroups. In the updated safety analysis (n=403), 15 of 270 patients (5.6%) receiving senaparib discontinued treatment due to treatment-emergent adverse events. The most common treatment-emergent adverse events (≥20%) in the senaparib arm were anaemia, neutropenia, leukopenia, thrombocytopenia, transaminases increased, nausea, abdominal pain, hypertriglyceridaemia, fatigue, hypercholesterolaemia and weight increased. No treatment-related deaths were reported.
In September 2026, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency adopted a positive opinion for senaparib. Senaparib is not yet authorised, pending a decision from the European Union.
Stephen Deacon, Chief Scientific Officer commented, “These updated results, with a median follow-up of around four years, add to the body of evidence in first-line maintenance treatment of advanced ovarian cancer. We are pleased to support our partner at ESMO, and we look forward to the European Commission’s decision and to continuing our dialogue with the clinical community.”
Pharmanovia entered into an exclusive partnership with IMPACT in July 2026. Under the licensing agreement, Pharmanovia has exclusive manufacturing, development and commercialisation rights for senaparib as maintenance monotherapy for advanced epithelial high-grade ovarian, fallopian tube and primary peritoneal cancer across 66 countries, including all 27 European Union member states, as well as the United Kingdom, Norway, Iceland, Switzerland, Liechtenstein, Australia, New Zealand and countries in the Middle East and North Africa.
