What this trial studies

This clinical trial investigates the effects of Maitake mushrooms on immune function in adults undergoing systemic cancer treatment, such as chemotherapy or CD4/6 inhibitors. Participants will receive Black Maitake Prothera alongside their conventional cancer therapies to assess any potential immunomodulatory benefits. The study aims to clarify the role of Maitake in integrative cancer care, particularly its effectiveness in enhancing the immune response during treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a confirmed cancer diagnosis who are currently receiving systemic cancer treatment in Ontario, Canada.

Not a fit: Patients with hematologic cancers, those who have taken mushroom supplements recently, or individuals with certain medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance the immune response in cancer patients, potentially improving treatment outcomes.

How similar studies have performed: While some studies have explored the benefits of Maitake mushrooms, this specific approach in conjunction with systemic cancer therapies is relatively novel.
