Adipose derived autologous mesenchymal stem cell therapy (Celltex Therapeutics)

This is a phase 2 open-label, 6 arms (1 study group and 1 control group for each joint category), randomized control group clinical study with 300 subjects diagnosed with osteoarthritis of knees (n=100), hips (n=100) and shoulders (n=100). The study subjects will be evaluated for disease-associated severity according to symptoms, such as pain, mobility, daily active life, and functions using arthritis society established specific measurement tools related to the joints (KOOS and KSS for OA-knees: HOOS and HHS for OA-hips and ASES and CSS for OA-shoulders).

This is a phase 2 multi-center, double-blind, randomized, placebo-control clinical trial with 200 subjects who have never been infected by COVID-19 (SARS-Cov-2 virus screen test negative, no blood SARS-Cov-2 IgM and IgG antibodies detected during enrollment) followed by a pilot study of 5 subjects to demonstrate the safety of proposed three-dose regimen of autologous AdMSCs infusions. The 100 study subjects who have previously banked their AdMSCs with Celltex, will receive three doses of autologous AdMSCs (approximately 200 million cells) intravenous infusion every three days. The 100 subjects in the control group who have previously banked their AdMSCs with Celltex will not receive any Celltex's AdMSC therapy but placebo treatments. All subjects are monitored for safety (adverse events/severe adverse events), COVID-19 symptoms, SARS-Cov-2 virus test, blood SARS-Cov-2 IgM and IgG antibodies tests, blood cytokine and inflammatory (CRP, IL_6, IL-10, TNFα) tests and disease severity evaluation for 6 months after the last dose of AdMSC infusion for the study group and 6 months after the enrollment for the control group.
