Cellular Biomedicine Group Announces Positive 48-Week Clinical Data of AlloJoin™ Human Adipose-Derived Mesenchymal Progenitor Cell (haMPC) Knee Osteoarthritis (KOA) China Phase I Trial

SHANGHAI, China and CUPERTINO, CA, USA I March 16, 2018 I Cellular Biomedicine Group Inc. (NASDAQ:CBMG) (“CBMG” or the “Company”), a clinical-stage biopharmaceutical firm engaged in the development of immunotherapies for cancer and stem cell therapies for degenerative diseases, today announces 48-week clinical data from the Phase I clinical trial in China for its allogeneic adipose-derived mesenchymal progenitor cell off-the-shelf therapy AlloJoin™ for Knee Osteoarthritis (KOA).  The data was presented on March 16, 2018 at the B. Riley FBR Inaugural China Healthcare Investing & Partnering Symposium (CHIPS) conference in Hangzhou, China, by Dr. ChengXiang (Chase) Dai, General Manager of the Company’s Stem Cell Business Unit.

“We are very encouraged by the latest data from our AlloJoin™ Phase I trial in China which demonstrates good safety and early efficacy for the prevention of cartilage deterioration. The recent regulatory guidelines issued by the CFDA have set a clearer clinical and commercialization pathway for our AlloJoin™ platform.  The success of the trial thus far, targeting an addressable market of 57 million KOA patients in China, prompted us to realign our resources to better focus on the China market.  We believe developing our KOA therapies in China is a faster path to market at a fraction of the cost of conducting US trials,” said Tony (Bizuo) Liu, CEO for the Company. “In that light, we are de-prioritizing the U.S. AlloJoin™ operation and the California Institute of Regenerative Medicine (CIRM) project has been terminated, effective March 14, 2018. The two AlloJoin™ cell banks, which we have created in the U.S, will now be stored in our Maryland facility for future use. We will continue to advance in China both our stem cell and CAR-T platforms as each becomes more widely approved.”

AlloJoin™ Phase I 48-week Data Analysis
The 48-week analysis of study data of 22 patients demonstrated AlloJoin™ off-the-shelf allogeneic stem cell therapy for KOA to have good safety tolerance and early signs of efficacy in preventing cartilage deterioration. The total WOMAC scores (consisting of pain, stiffness and function scores of joints) as a primary end point showed a significant improvement at 12 weeks post AlloJoin™ cell therapy and continued improvement at 48 weeks. The secondary evaluation end point, the data of 3D spoiled gradient-recalled echo (SPGR) quantitative magnetic resonance imaging (MRI) for whole knee cartilage volume at 48 weeks showed an increased tendency when compared with that at baseline 0 weeks, and as compared with normal cartilage deterioration as a result of aging.

The presentation with detailed data can be viewed on the Company website under the Investor section.

“The analysis of this early stage clinical study has indicated a good safety and potential efficacy for an off-the-shelf allogeneic haMPC therapy, which would allow us to continue to advance clinical trials to confirm efficacy of such cell therapy in preventing cartilage deterioration. The Company believes that the opportunity for patients to prevent further knee cartilage degeneration and improve the long-term quality of life using stem cells could be preferable to undergoing drug treatment with adverse side effects or painful and invasive knee replacement surgery. If this allogeneic cell therapy, which takes less time and cost to produce as compared to autologous therapies, would be proved effective and approved for clinical use, then 57 million symptomatic KOA patients in China may have access to a more hopeful therapy, which could stop or delay cartilage deterioration and also improve joint pain, stiffness and movement function,” commented Dr. ChengXiang (Chase) Dai, General Manager, Stem Cell Business Unit of CBMG.

Common side effects were temporary local reactions including soreness and swelling at the injection site and negligible systemic reactions, except one patient that reported transient dizziness after inter-articular injection of AlloJoin™. Two patients who underwent one dose of injections dropped out of the study as they reported their knee joints were more painful after injection. To date, no serious adverse events (SAE) related to AlloJoin™ therapy have been reported.

About the AlloJoin™ Clinical Trial
The Phase I clinical research trial for AlloJoin™, registered at ClinicalTrials.gov under the number NCT02641860, is conducted in China at Shanghai Renji Hospital, one of the largest teaching hospitals in China, with Principal Investigator Chunde Bao, MD, Professor of Medicine, Vice Chairman of the Chinese Rheumatology Association. The single-center study enrolled 22 patients with knee osteoarthritis (Kellgren-Lawrence Grading Scale: grade II-III) to participate in a randomized, double-blind trial with three different cell dose groups.

The primary endpoints for this trial were safety and knee-related pain, stiffness and function measured using the Western Ontario and McMaster Universities (WOMAC) osteoarthritis index questionnaire. The secondary endpoints were cartilage repair at 12 months by assessment of changes of the knee joint cartilage’s volume measured with 3D SPGR quantitative MRI, in addition to VAS, SF-36 and Whole-Organ Magnetic Resonance Imaging Score (WORMS) scores.

Of the 22 patients enrolled, 20 patients underwent two doses of intra-articular injections of AlloJoin™ at 3-week intervals. All 20 of those patients were followed up and evaluated for safety and efficacy at 4 weeks, 8 weeks, 12 weeks, 24 weeks, 36 weeks, and 48 weeks. Nineteen of the 22 patients were evaluated by third-party quantitative MRI assessment of the whole joint cartilage volume at baseline and 48 weeks. The Company has completed data management and statistics analysis via third-party statistics unit, Department of Health Statistics, Public Health College, Fudan University.
