DESTINY-Endometrial01: A Phase III Study of Trastuzumab Deruxtecan Plus Rilvegostomig or Pembrolizumab as First-Line Treatment of HER2-Expressing (IHC 3+/2+), Mismatch Repair Proficient (pMMR) Endometrial Cancer

Plain-language summary
DESTINY-Endometrial01 will investigate the efficacy of first-line T-DXd + rilvegostomig (Arm A) and/or T-DXd+ pembrolizumab (Arm B) when compared to chemotherapy (carboplatin + paclitaxel) + pembrolizumab (Arm C), by assessment of progression free survival (PFS), as assessed by BICR, in participants with HER2-expressing (IHC 3+/2+), pMMR, primary advanced (Stage III/IV) or recurrent EC.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
. Primary Stage III (per FIGO 2023) disease with measurable disease at baseline per RECIST 1.1 based on the investigator's assessment.
. Primary Stage IV (per FIGO 2023) disease regardless of presence of measurable disease at baseline.
. Recurrent disease regardless of presence of measurable disease at baseline.
. No prior chemotherapy for the treatment of EC, except for one prior line of adjuvant/ neoadjuvant chemotherapy with curative intent (chemotherapy or chemoradiation) if completed ≥ 6 months prior to signature of the main ICF. Prior trastuzumab in the adjuvant/neoadjuvant setting is allowed.
. No prior exposure to antibody-drug conjugates or immune checkpoint inhibitors
. Participants may have received prior radiation therapy for the treatment of endometrial cancer. Adequate treatment washout period is required
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Progression-free survival (PFS), as assessed by BICR
Timeframe: Until progression or death due to any cause (assessed up to approximately 45 months).
. Participants may have received prior hormonal therapy for the treatment of endometrial cancer. Adequate treatment washout period is required
Exclusion criteria
. Lung-specific intercurrent clinically significant illnesses including, but not limited to, any underlying pulmonary disorder (e.g., pulmonary emboli within 3 months of the study enrollment, severe asthma, severe chronic obstructive pulmonary disease \[COPD\], restrictive lung disease, etc.).
. Any autoimmune, connective tissue or inflammatory disorders where there is documented, or a suspicion of pulmonary involvement at the time of screening.
