IRVINE, Calif. — September 13, 2022 — Immunis Inc., a private biotechnology company developing a novel treatment for age and disease-related immune decline, has formally signed a clinical trial agreement with California Institute of Regenerative Medicine (CIRM) Alpha Stem Cell Clinics Network to initiate STEM-MYO Phase 1/2a clinical trials. The trials will assess the safety and tolerability of Immunis’ immunomodulatory secretome product, IMM01-STEM, in patients with muscle atrophy related to knee osteoarthritis, an inflammatory disease that is a leading cause of disability in elderly adults.

Immune system health gradually declines with age and contributes to an array of degenerative maladies within the body, including muscle atrophy. This age-related muscle atrophy, sarcopenia, in addition to muscle wasting from disuse or disease, negatively affects quality of life. No treatments are available to attenuate muscle loss or enhance muscle regeneration. IMM01-STEM is a novel secretome product composed of natural immunomodulators with efficacious cytoskeletal remodeling properties to address these clinical needs.

“We are excited to have reached this clinical milestone that allows us to begin exploring the potential impact of IMM01-STEM in the treatment of an otherwise untreatable disorder,” says Erin Curry, Director of Medical Affairs at Immunis Inc.
