Official title: A Phase 3, Open-Label, Multicenter, Randomized Study of Raludotatug Deruxtecan (MK-5909, R-DXd) With or Without Bevacizumab Versus Standard-of-Care Platinum-Based Doublet Chemotherapy With or Without Bevacizumab in Participants With Advanced Platinum-Sensitive High-Grade Serous or High-Grade Endometrioid Epithelial Ovarian, Primary Peritoneal, or Fallopian Tube Cancer Who Have Progressed During First-Line PARPi Maintenance (ENGOT-ov107 / GOG-3142 / REJOICE-Ovarian05)
Run by Merck Sharp & Dohme LLC · NCT07743164 · Data updated 2026-11-12
This trial tests whether adding raludotatug deruxtecan (R-DXd) to or without bevacizumab helps people with advanced ovarian cancer that progressed after PARP-inhibitor maintenance.

Is this trial a fit for you?
✓Likely a good fit
Adults with advanced high-grade ovarian, peritoneal, or fallopian tube cancer who progressed on PARP-inhibitor maintenance after platinum therapy.
✕Probably not a fit
Patients with non-target histologies, extensive prior therapies, or inability to tolerate study treatments may not benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a Phase 3 interventional trial evaluating R-DXd, an antibody-drug conjugate, given with or without bevacizumab, in patients with advanced high-grade ovarian or related cancers who progressed on PARP-inhibitor maintenance after platinum therapy. Participants may also receive standard chemotherapy agents such as carboplatin, paclitaxel, or gemcitabine as part of treatment regimens. The study aims to determine whether adding R-DXd improves outcomes compared with regimens without it. Eligibility includes high-grade serous or endometrioid histology, platinum-sensitive disease, and adequate recovery from prior therapies. Exclusions include certain non-target histologies and specific prior treatment considerations.
Why it matters
Potential benefit: If successful, the treatment could improve tumor control and survival for patients with this disease.
How similar studies have gone: Similar antibody-drug conjugate approaches have shown activity in ovarian cancer, with ongoing research to define added benefit.

The main inclusion criteria include but are not limited to the following: * Has a histologically or cytologically documented advanced high-grade serous or high-grade endometrioid epithelial ovarian, primary peritoneal, or fallopian tube cancer. * Has received 1 line of platinum-based therapy with a minimum of 4 cycles of platinum-doublet chemotherapy and have platinum-sensitive disease. * Has received a poly (ADP-ribose) polymerase inhibitor (PARPi) as maintenance treatment after the first line platinum-based chemotherapy course and experienced radiographic progression during treatment or within 42 days of the last dose of PARPi. * Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 assessed within 7 days before randomization. * Has recovered from any AEs due to previous anticancer therapies. The main exclusion criteria include but are not limited to the following: * Has clear cell, mucinous, or sarcomatous histology, mixed tumors containing any histology, or low-grade/borderline ovarian cancer. * Has a history of thrombotic disorders, hemorrhage, hemoptysis, or active GI bleeding within 6 months before randomization. * Has uncontrolled or significant cardiovascular disease. * Has clinically severe pulmonary compromise resulting from intercurrent pulmonary illnesses including, but not limited to, any underlying pulmonary disorder (ie, pulmonary emboli within 3 months of randomization, severe asthma, severe chronic obstructive pulmonary disease \[COPD\], restrictive lung disease, pleural effusion) and any autoimmune, connective tissue, or inflammatory disorders with potential pulmonary involvement (eg, rheumatoid arthritis, Sjogren's syndrome, sarcoidosis), or prior pneumonectomy. * Has received chronic steroid treatment, with some exceptions. * Has current, clinically relevant bowel obstruction (including subocclusive disease) including obstruction related to underlying epithelial ovarian cancer, abdominal fistula or GI perforation, intra-abdominal abscess, or evidence of rectosigmoid involvement by pelvic exam. * Has known additional malignancy that is progressing or has required active treatment within the past 3 years.
