Blocking AXL to improve treatment for aggressive endometrial cancer

Project 2: Inhibiting AXL to Improve Treatment Response in Endometrial Cancer

NIH-funded research Washington University · NIH-11191545

This project tests whether adding batiraxcept (AVB-500), an AXL-blocking drug, to standard paclitaxel helps people with recurrent aggressive endometrial cancers respond better to treatment.

What this research studies

You would receive batiraxcept together with standard paclitaxel chemotherapy while doctors monitor side effects and tumor response. The team will collect blood and tumor tissue to look for markers that predict who benefits and to understand how AXL blocking changes tumor biology. Researchers plan to enroll people with recurrent uterine serous carcinoma or grade 3 endometrioid endometrial cancer and follow them during treatment at the trial site. Findings may also inform combining AXL blockade with anti-angiogenic therapies.

Who could benefit from this research

Good fit: Adults with recurrent uterine serous carcinoma or grade 3 endometrioid endometrial cancer who are eligible for paclitaxel chemotherapy are the intended candidates.

Not a fit: Patients with low-grade endometrial cancers, those who are not candidates for paclitaxel, or tumors lacking AXL-related biology may not benefit from this approach.

Why it matters

Potential benefit: If successful, the combination could improve how well chemotherapy works for aggressive endometrial cancers and help identify patients most likely to benefit.

How similar studies have performed: Preclinical data and early laboratory results show batiraxcept can boost response to paclitaxel and may enhance anti-VEGF drugs, but clear clinical benefit is still being tested.
