Significance of Immunis’ Work

Every individual experiences a decline in immune system health as they age, which contributes to degenerative conditions throughout the body, including muscle atrophy. Age-related muscle atrophy (sarcopenia) and muscle wasting from disuse or disease significantly decreases quality of life. Mitigating the loss of muscle and improving muscle recovery remain unmet medical needs. Our goal is to utilize the secretome as a means of driving specific immune responses to overcome manifestations of age-related disease.

Clinical Trials

Target: Muscle atrophy; sarcopenia
Treatment: IMM01-STEM
ClinicalTrials.gov Identifier: NCT05211986

Research is being undertaken to determine whether IMM01-STEM (STEM) can be beneficial in diseases characterized by muscle atrophy. STEM is a secretome product derived from partially differentiated pluripotent stem cells concentrated with regenerative molecules. The FDA-approved Phase 1/2a clinical trial with STEM is a single-center, open-label, dose-escalation study to assess safety and tolerability. STEM is administered via intramuscular (im) injection twice per week for 4 weeks to participants with muscle atrophy related to knee osteoarthritis. A preliminary evaluation of the efficacy of STEM in other indications such as Alzheimer’s Disease and multisystem senescence is also being performed.

The Phase 1/2a clinical trial is being conducted at the University of California Irvine Medical Center, UCI Health. UCI Health is part of the California Institute of Regenerative Medicine's Alpha Stem Cell Clinic Network. We invite you to learn more about these clinical trial opportunities.

STEM Pre-Clinical Efficacy

In non-clinical mouse studies in aged mice and in a model of muscle atrophy, treatment with STEM was shown to increase muscle mass, increase muscle strength and diminish skeletal muscle fibrosis. These results demonstrate the efficacy of STEM in attenuating loss of muscle mass and muscle fiber area during disuse atrophy in aged mice. We invite you to learn more about these results published in GeroScience.

STEM Product Formulation

STEM is a non-cell-based secretome product derived from partially differentiated human stem cells and is composed of a multitude of pro-regenerative factors involved in immunomodulation, cytoskeleton remodeling, and growth factor-mediated cellular signaling. It is a sterile and nonpyrogenic aqueous solution manufactured under cGMP conditions. The STEM solution does not contain live cells or any cell fragments. STEM is all natural, all human, and contains a multitude of factors known to benefit immune system development and health.

Alpha Stem Cell Clinic at the UCI Medical Center

UCI Health is part of the California Institute of Regenerative Medicine’s (CIRM) Alpha Stem Cell Clinic Network, which is supporting Immunis’ Phase 1/2a clinical study. The investigations to assess the efficacy of Immunis’ immunomodulatory secretome product, STEM, in the context of muscle atrophy is headed by Dean Wang, MD, alongside Brian Young Kim, MD, MS, Steven Yang, MD, MBA and Christopher Kroner, MD, MPH. The Alpha Clinics Network funded through CIRM has one unifying goal: to accelerate the development and delivery of stem cell therapies to patients.
