Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients with TP53 wild-type advanced or recurrent endometrial cancer who have completed chemotherapy and achieved a response.
✕Probably not a fit
Patients with sarcomas, small-cell carcinomas, or those who have received prior immune or investigational therapies may not benefit from this study.

What this trial studies
This study evaluates the use of navtemadlin as a maintenance treatment for patients with advanced or recurrent endometrial cancer who have shown a complete or partial response to prior chemotherapy. The trial is divided into two parts: the first part assesses the safety and efficacy of two different doses of navtemadlin compared to an observational control arm, while the second part compares the selected Phase 3 dose of navtemadlin to a placebo. The goal is to determine the optimal dosing and effectiveness of navtemadlin in prolonging patient responses.
Why it matters
Potential benefit: If successful, this treatment could provide a new maintenance therapy option that improves outcomes for patients with advanced endometrial cancer.
How similar studies have gone: While there have been studies on maintenance therapies in cancer, the specific use of navtemadlin in this context is novel and has not been extensively tested.
