Can a 'Smart Bomb' drug outsmart recurrent ovarian cancer?
NCT ID NCT07743164
First seen Aug 03, 2026 · Last updated Sep 11, 2026 · Updated 6 times
Summary
This trial is testing whether a new drug called raludotatug deruxtecan (R-DXd), given alone or with bevacizumab, can help people with advanced ovarian cancer live longer and delay cancer growth compared to standard chemotherapy. The study includes adults with high-grade serous or endometrioid ovarian, peritoneal, or fallopian tube cancer that has returned after initial platinum-based treatment and PARP inhibitor maintenance. R-DXd is an antibody-drug conjugate designed to target cancer cells and deliver a toxic agent directly to them. The trial will compare progression-free survival and overall survival between the treatment groups.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- raludotatug deruxtecan (R-DXd), an antibody-drug conjugate that targets cancer cells and delivers a toxic payload, given alone or with bevacizumab
- What this could lead to
- If successful, this could provide a new, more effective treatment option for people with advanced ovarian cancer that has returned after initial therapy, potentially extending the time before the cancer progresses and improving overall survival.
- What could go wrong
- This is a phase 3 trial, but the drug is still experimental. It may not prove more effective than standard chemotherapy, and it could have side effects, including potential toxicity from the antibody-drug conjugate. Results will take time and may not apply to all patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
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.
