About this study

Official title: A Phase 3, Multicenter, Randomized, Open-label Trial of Trastuzumab Deruxtecan Versus Standard of Care Chemotherapy With or Without Radiotherapy as Adjuvant Treatment for HER2-Expressing (IHC 3+/2+) Endometrial Cancer (DESTINY-Endometrial02/ GOG-3122/ ENGOT-en30/GINECO)

This study is designed to assess efficacy and safety of T-DXd adjuvant therapy, with or without radiotherapy, post-surgery in anticancer treatment naïve (including neoadjuvant therapy) endometrial cancer with various HER2 expression levels.

Read the detailed description

This is a global, multicenter, open-label, phase 3 study to evaluate the efficacy and safety of T-DXd versus SoC chemotherapy with or without radiotherapy as adjuvant treatment in participants with HER2-expressing (IHC 3+/2+) endometrial cancer. Participants will be randomized 1:1 to either T-DXd or SoC chemotherapy. The primary objective will assess disease-free survival as assessed radiographically by BICR or by histopathologic confirmation of disease recurrence per local assessment.

T-DXd (Enhertu®) is a HER2 directed ADC composed of a humanized anti-HER2 IgG1 mAb with the same amino acid sequence as trastuzumab, which includes a plasma-stable, selectively cleavable linker and potent topoisomerase I inhibitor payload (a derivative of exatecan) that leverages the clinically validated DXd ADC technology.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Trastuzumab DeruxtecanDrug

    Also called T-DXd, ENHERTU®

    T-DXd will be administered at a dose of 5.4 mg/kg IV Q3W.

  • ChemotherapyDrug

    Carboplatin AUC 5 or 6 and paclitaxel will be administered at a dose of 175 mg/m2 Q3W, or carboplatin AUC 5 or 6 and paclitaxel 175 mg/m2 Q3W with or without radiation therapy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Disease-Free Survival (DFS) as Assessed by Blinded Independent Central Review or by Histopathologic Confirmation of Disease Recurrence per Local Assessment

    DFS will be assessed radiographically by BICR or by histopathologic confirmation of disease recurrence per local assessment.

    Measured: From randomization to the first documented local regional recurrence, distant metastasis, or death due to any cause, whichever occurs first, up to approximately 51 months

Secondary outcomes (1)
  1. Overall Survival

    Overall Survival is defined as the time interval from the date of randomization to the date of death due to any cause.

    Measured: From randomization to the date of death due to any cause, approximately 63 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Trastuzumab Deruxtecan and Chemotherapy in people with Endometrial Cancer, run by Daiichi Sankyo at 86 sites in 15 countries.

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 5 inclusion and 8 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 27 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 86 sites in China, Japan, United States, Italy, Argentina and 10 more countries. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 Contact for Trial Information (908-992-6400, CTRinfo_us@daiichisankyo.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Disease-Free Survival (DFS) as Assessed by Blinded Independent Central Review or by Histopathologic Confirmation of Disease Recurrence per Local Assessment (time frame: From randomization to the first documented local regional recurrence, distant metastasis, or death due to any cause, whichever occurs first, up to approximately 51 months). 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 27 Oct 2026.
