What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests Trastuzumab Deruxtecan, a targeted cancer therapy, to evaluate its effectiveness for endometrial cancer patients post-surgery. The goal is to determine if it can prevent cancer recurrence, with or without radiotherapy. Participants will receive either this new treatment or standard chemotherapy for comparison. Suitable candidates have recently been diagnosed with endometrial cancer that remains localized or regional and have specific HER2 protein levels in their cancer cells. As a Phase 3 trial, this study represents the final step before FDA approval, providing participants an opportunity to contribute to potentially groundbreaking cancer treatment advancements.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that Trastuzumab Deruxtecan (T-DXd) is generally well-tolerated by patients with HER2-expressing cancers. One study found that the side effects align with existing knowledge about this treatment. Common side effects include nausea, tiredness, and hair loss, which most patients manage well. However, the treatment has been linked to a risk of interstitial lung disease (ILD), a lung condition that requires monitoring. Despite this risk, the treatment remains approved for other cancers like breast and stomach cancer. Overall, the safety information is reassuring, but discussing any concerns with a doctor is advisable.12345

Why do researchers think this study treatment might be promising for endometrial cancer?

Trastuzumab Deruxtecan is unique because it combines an antibody with a chemotherapy drug, specifically targeting cancer cells in endometrial cancer. This approach allows for direct delivery of the chemotherapy to the cancer cells, potentially reducing harm to healthy cells and leading to fewer side effects compared to standard chemotherapy. Researchers are excited about this treatment because it represents a more precise attack on cancer cells, which could improve effectiveness and patient outcomes compared to traditional options like carboplatin and paclitaxel.

What evidence suggests that Trastuzumab Deruxtecan might be an effective treatment for endometrial cancer?

Research has shown that trastuzumab deruxtecan (T-DXd), which participants in this trial may receive, could effectively treat endometrial cancer with the HER2 protein. This treatment has proven successful in other similar HER2-positive cancers. Many endometrial cancer cases have this protein. Studies have found that T-DXd can help patients live longer and respond well to treatment if their cancer is HER2-positive. The FDA has already approved T-DXd for some gynecologic cancers, suggesting it could be effective. Early research also indicates that T-DXd has manageable side effects, similar to those observed in past studies. Meanwhile, another group in this trial will receive standard care chemotherapy, which includes carboplatin and paclitaxel, with or without optional radiotherapy or chemoradiotherapy.12467

Are You a Good Fit for This Trial?

This trial is for adults over 18 with newly diagnosed FIGO 2023 Stage IIC or III endometrial cancer. Participants must have a confirmed epithelial carcinoma diagnosis, excluding sarcomas but including carcinosarcomas, and show HER2-expression (IHC 3+/2+). Adequate tumor tissue from surgery must be available for testing.
