What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing whether taking beta-glucan by mouth can help boost the immune system in patients with advanced melanoma who are already receiving Pembrolizumab. The goal is to see if this combination can make the immune system more effective at preventing cancer from coming back. Researchers will look at how well the immune system works and track patient outcomes like cancer recurrence and survival. Recent studies showed promising results about the combination of β-glucans and immune checkpoint inhibitors for patients affected by different solid tumors.

Do I need to stop my current medications for the trial?

The trial does not specify if you need to stop your current medications, but you cannot participate if you are on ongoing immunosuppressive therapy.

Is beta-glucan safe for human use?

Beta-glucans are generally considered safe and have been used in various clinical studies for their immune-boosting and other health benefits. Studies in animals, such as rats, have shown no significant toxicity even at high doses, and they have been used safely in humans for conditions like cancer and metabolic disorders.12345

How does the beta-glucan treatment for melanoma differ from other treatments?

Beta-glucan is unique because it is a natural compound that boosts the immune system, particularly by activating natural killer (NK) cells, which helps fight melanoma. Unlike traditional chemotherapy, beta-glucan can be taken orally and enhances the effects of other cancer treatments, making it a promising complementary therapy.15678

What evidence supports the effectiveness of the treatment Beta-Glucan for melanoma?

Research shows that β-glucan, a natural compound, can help reduce tumor size and improve survival rates in melanoma by boosting the immune system, particularly through the action of natural killer cells. Additionally, β-glucans have been shown to enhance the effects of chemotherapy and reshape immune cells to better fight cancer.14569

Are You a Good Fit for This Trial?

This trial is for adults with Stage III-IV melanoma who are starting or have been on Pembrolizumab therapy. They should not currently have the disease, be new to treatment or haven't had it in over 6 months, and must be able to swallow pills. People with a history of beta-glucan sensitivity, other cancers, immune suppression therapy, serious illnesses like heart failure or infections, or certain mental health issues can't join.

What Are the Treatments Tested in This Trial?

Interventions

  • Beta-Glucan
Trial Overview The study is testing how Beta-Glucan affects the immune response in patients taking Pembrolizumab for advanced melanoma. It aims to see if this combination improves outcomes compared to what's expected from Pembrolizumab alone.

Published Research Related to This Trial

Insoluble yeast-derived β-glucan significantly reduced tumor weight and lung colonies in melanoma models, leading to improved overall survival rates in tested animals.
The study suggests that β-glucan enhances the effects of standard chemotherapy and protects blood cells, with some of its benefits linked to its direct action on natural killer (NK) cells.
Glucan Supplementation Has Strong Anti-melanoma Effects: Role of NK Cells.Vetvicka, V., Vetvickova, J.[2015]
Certain β-glucans, specifically curdlan, yeast-b, and zymosan, can re-polarize immune-suppressive macrophages into a more active M1-like phenotype, enhancing their ability to produce immune signals and recruit other immune cells.
These β-glucans promote the secretion of chemo-attractants that help in drawing monocytes and neutrophils to the tumor site, potentially improving anti-cancer T-cell responses in the immune-suppressive tumor microenvironment.
Curdlan, zymosan and a yeast-derived β-glucan reshape tumor-associated macrophages into producers of inflammatory chemo-attractants.de Graaff, P., Berrevoets, C., Rӧsch, C., et al.[2023]
β-glucans, found in foods like mushrooms, have shown potential therapeutic effects for various conditions, including metabolic syndrome, obesity, and immune-mediated diseases, due to their ability to modulate metabolism and the gut microbiome.
Despite their promising applications, significant challenges remain in understanding the diverse mechanisms of action and the variability in effects of different β-glucan preparations, which complicates their clinical testing and therapeutic translation.
