Boosting the body's defenses against recurrent ovarian cancer and managing fluid buildup

Targeting complement to enhance antitumor immunity and control malignant effusions in patients with recurrent epithelial ovarian cancer

NIH-funded research Roswell Park Cancer Institute Corp · NIH-11141676

This project explores a new way to strengthen the immune system against recurrent ovarian cancer and reduce fluid accumulation by targeting a specific part of the immune response.

What this research studies

Ovarian cancer can be challenging to treat, especially when it returns, and current immune therapies don't always work well. We've found that certain immune cells, called neutrophils, can sometimes suppress the body's ability to fight the cancer, and this process involves a system called complement. This project aims to block the complement system using a medication called APL-2 to help the immune system better attack cancer cells. We are conducting a clinical trial to see if APL-2 can improve the immune response and help control fluid buildup in patients with recurrent ovarian cancer.

Who could benefit from this research

Good fit: This opportunity is for patients with recurrent epithelial ovarian cancer who also experience persistent malignant effusions, which is fluid buildup.

Not a fit: Patients whose cancer is not recurrent or who do not have malignant effusions may not be suitable for this specific approach.

Why it matters

Potential benefit: If successful, this approach could make immunotherapy more effective and help manage painful fluid accumulation in patients with recurrent ovarian cancer.

How similar studies have performed: Early findings in human samples and animal models suggest that targeting the complement system can boost anti-tumor immunity, and the drug APL-2 has shown to be safe in prior use.
