Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
* Age =18 years at the time of screening and female.
* Histologically confirmed diagnosis of epithelial endometrial carcinoma. All histologies, including carcinosarcomas, will be allowed. Sarcomas will not be allowed.
* Patient must have endometrial cancer in one of the following categories:

1. Newly diagnosed Stage III disease (measurable disease per RECIST 1.1 following surgery or diagnostic biopsy),
2. Newly diagnosed Stage IV disease (with or without disease following surgery or diagnostic biopsy)
3. Recurrence of disease (measurable or non-measurable disease per RECIST 1.1) where the potential for cure by surgery alone or in combination is poor.
* Naïve to first line systemic anti-cancer treatment. For patients with recurrent disease only, prior systemic anti-cancer treatment is allowed only if it was administered in the adjuvant setting and there is at least 12 months from date of last dose of systemic anti-cancer treatment administered to date of subsequent relapse
* FPPE tumor sample must be available for MMR evaluation.
* Has Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 within 7 days of starting study treatment.
