Tuvusertib Combined With Niraparib or Lartesertib in Participants With Epithelial Ovarian Cancer (DDRiver EOC 302) (NCT06433219)

An Open-label, Multicenter, Randomized Phase 2 Study of the ATR Inhibitor Tuvusertib in Combination With the PARP Inhibitor Niraparib or the ATM Inhibitor Lartesertib in Participants With BRCA Mutant and/or Homologous Recombination deficiency (HRD)-Positive Epithelial Ovarian Cancer That Progressed on Prior PARP Inhibitor Therapy (DDRiver EOC 302)

🔵 Active, Not Recruiting Phase2 💊 Investigational Drug / Biologic Sponsor: EMD Serono Research & Development Institute, Inc.

🩺 Plain-English Summary (8th-Grade Level)

The purpose of this study is to measure the effect and safety of treatment with tuvusertib combined with either niraparib or lartesertib in participants with epithelial ovarian cancer and to assess any differences between tuvusertib monotherapy and combination therapy. The participants will previously have progressed while treated with a poly ADP ribose polymerase (PARP) inhibitor. The primary objectives of this study are to assess the effect of the treatment in terms of overall response, i.e. whether the tumor disappears, shrinks, remains unchanged, or gets worse and safety in terms of adverse events.
