UCI opens clinical trial of stem cell-derived therapy for knee arthritis

Early-phase study is first in the U.S.

Irvine, Calif. – UCI Health and UCI Alpha Clinic have launched the first U.S. clinical trial to test the safety and tolerability of IMM01-STEM in patients with knee osteoarthritis to prevent muscle atrophy.

Up to 18 patients ranging in age from 50 to 75 will be enrolled in the phase 1/2a clinical trial sponsored by Immunis Inc., a biotech company developing novel treatments for age-related immune decline. 

People with knee osteoarthritis tend to reduce their physical exercise because of pain. Muscles in the leg help support the knee joint, so keeping them strong and healthy can limit the symptoms of osteoarthritis. However, when exercise causes pain, it can be difficult for people to maintain or rebuild the muscle strength needed to prevent worsening knee arthritis.

“Conducting clinical trials to validate whether stem cell-derived treatments might be effective for patients suffering from muscle atrophy is a key part of our mission,” said UCI Health orthopedic surgeon Dean Wang, MD, the trial's principal investigator and associate professor of orthopaedics at the UCI School of Medicine. 

“IMM01-STEM is an injectable solution composed of proteins that were created by stem cells," Wang said. "It has been shown to increase muscle mass and strength in animal studies.”

The trial is the first to study this therapy in humans.

“Muscle atrophy is a degenerative condition experienced by every aging human but is exacerbated when coupled with immobilization, as it is in patients with knee osteoarthritis,” said Tom Lane, PhD, chief science officer of Immunis. “We hope to alleviate suffering, get better outcomes for knee osteoarthritis and offer a new tool to combat immune-mediated symptoms of aging in general.”

According to Immunis, IMM01-STEM is a one-of-a-kind secretome product comprised of natural immunomodulators with potent cytoskeletal remodeling properties that demonstrates the ability to address these clinical needs. In pre-clinical studies published last year, it improved muscle mass and strength during disuse and recovery in aging mouse models. In August, the U.S. Food and Drug Administration approved an investigational new drug application for the trial, which is now open at UCI.

“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,” said Erin Curry, director of medical affairs at Immunis.
