Effect of beta-glucan on immune response in advanced melanoma patients

Beta Glucan's Effect on Pembrolizumab Immunologic Response in Stage III-IV Melanoma

Not applicable Interventional University of Louisville · NCT04513028

This study is testing if taking beta-glucan along with Pembrolizumab can boost the immune response in patients with advanced melanoma and help them live longer without the cancer coming back.

What this trial studies

This clinical pilot study investigates the impact of oral beta-glucan on the immune system of patients with advanced stage III-IV melanoma who are receiving adjuvant Pembrolizumab. The study aims to evaluate whether the combination of beta-glucan and Pembrolizumab can enhance immunologic responses, such as reducing peripheral myeloid-derived suppressor cells (MDSCs) and improving T effector cell function. Secondary outcomes will focus on clinical endpoints, including recurrence rates, progression-free survival, and overall survival among participants. The study will enroll treatment-naïve patients or those who have not received treatment in the last six months.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with stage III-IV melanoma starting or continuing adjuvant Pembrolizumab without active disease.

Not a fit: Patients with a history of hypersensitivity to beta-glucan or those on ongoing immunosuppressive therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve immune responses and clinical outcomes for patients with advanced melanoma.

How similar studies have performed: While the combination of beta-glucan with immunotherapy is a novel approach, similar studies have shown promise in enhancing immune responses.
