Clinical Trials

Multiple Phase II clinical trials have evaluated this therapeutic candidate for treating conditions such as COVID-19 complicated by lymphocytopenia and refractory nontuberculous mycobacterial lung infections. Sponsored by Revimmune alongside academic and clinical collaborators—including Washington University School of Medicine, Memorial Sloan Kettering Cancer Center, M.D. Anderson Cancer Center, and Amarex Clinical Research—all of these studies have been terminated.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Cyperotundone binds to specific cellular regulatory targets to inhibit downstream inflammatory signaling cascades, consequently suppressing pro-inflammatory cytokine expression and preventing cellular damage. This attenuation of hyperinflammatory signaling helps restore host immune homeostasis, offering clinical relevance for addressing immune dysfunction in conditions such as COVID-19 with lymphocytopenia and nontuberculous mycobacterial infections.

Appendix RUO and cGMP Quality Standards
