About this study
Official title: A Phase 2, Open-label, Multicenter, Randomized Study of Trastuzumab Deruxtecan Versus Investigator's Choice Chemotherapy in Recurrent Ovarian Cancer That Progressed on Prior PARP Inhibitor Therapy: TROY (APGOT-OV14)
Ovarian, fallopian tube, and peritoneal cancers are often diagnosed at an advanced stage, requiring chemotherapy. Recently, the standard treatment, platinum-based chemotherapy plus PARP inhibitors, has extended disease-free survival (PFS). However, most patients eventually develop resistance to PARP inhibitors and become unresponsive to conventional treatments. Therefore, an effective standard treatment for patients who relapse after PARP inhibitor resistance has not yet been established. Meanwhile, HER2 protein expression has been identified in some patients, drawing attention as a new therapeutic target.
Trastuzumab deruxtecan (T-DXd), an antibody-drug conjugate (ADC) targeting HER2, has already demonstrated efficacy and safety in other HER2-positive cancers. This study aimed to explore the potential of T-DXd as a new treatment option by evaluating the efficacy and safety of T-DXd in patients with ovarian, fallopian tube, and peritoneal cancer who relapsed after PARP inhibitor treatment and who express HER2.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Trastzumab Deruxtecan, Bevacizumab and Platinum Based Chemotherapy in people with Ovarian Cancer and Ovarian Carcinoma, Recurrent, run by Yonsei University at 1 site in South Korea.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 19 inclusion and 26 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 20 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Jung-Yun LEE, PhD. (+2-2228-2760, JUNGYUNLEE@yuhs.ac), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression Free Survival (PFS) in HER2 IHC 1+/2+/3+ population (time frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 5 years.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Apr 2026.
