What this trial studies

This open-label, multi-center Phase II study evaluates the effectiveness of Envafolimab alone or in combination with Lenvatinib in patients diagnosed with advanced endometrial cancer. The primary goal is to assess the objective response rate of these treatments in patients who have not responded to standard chemotherapy. Participants will be monitored for measurable target lesions and overall health status throughout the trial. The study aims to provide insights into new treatment options for this challenging condition.

Who should consider this trial

Good fit: Ideal candidates include individuals with advanced, recurrent, or metastatic endometrial cancer who have failed or are intolerant to standard first-line chemotherapy.

Not a fit: Patients with early-stage endometrial cancer or those who are candidates for curative surgery or radiation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could offer a new treatment option for patients with advanced endometrial cancer who have limited alternatives.

How similar studies have performed: Other studies have explored similar combinations of immunotherapy and targeted therapy in various cancers, showing promising results, but this specific combination is relatively novel.
