Cellular Biomedicine Group Announces Positive 48-Week Data From Phase IIb Clinical Trial for Knee Osteoarthritis Stem Cell ReJoin® Therapy
SHANGHAI, China and CUPERTINO, Calif., Jan. 13, 2016 (GLOBE NEWSWIRE) -- Cellular Biomedicine Group Inc. (NASDAQ:CBMG) (“CBMG” or the “Company”), a biomedicine firm engaged in the development of effective stem cell therapies for degenerative diseases and immunotherapies for cancer, today announced positive 48-week clinical data from the Phase IIb trial of its human adipose-derived mesenchymal progenitor cell (haMPC) therapy ReJoin® for Knee Osteoarthritis (KOA). The data was presented January 12th at the 8th Annual BioTech Showcase investor conference held in San Francisco, CA. The Company continues to be encouraged by the latest data from its ReJoin® trials. Objective measurement of cartilage volume by 3D SPGR quantitative magnetic resonance imaging (MRI) indicated significant increase of cartilage volume following ReJoin® therapy, as opposed to further cartilage deterioration normally found in untreated patients1. The Company believes that the opportunity for patients to regenerate their damaged knee cartilage and improve the long-term quality of life using their own stem cells could be more preferable than undergoing drug treatment with adverse side effects or painful and invasive knee replacement surgery or other invasive surgical procedures. The positive preliminary results from these trials bring the Company closer to commercialization of ReJoin® therapy in China, where there are more than 57 million KOA patients with no approved KOA treatment for structure modification available. ReJoin® Phase IIb 48-week Data Analysis The 48-week end of study data of 53 patients shows the primary and secondary endpoints of ReJoin® therapy group having all improved significantly compared to their baseline, which has confirmed some of the Company’s Phase I/IIa results (view report here). The total WOMAC scores (consisting of pain, stiffness and function scores of joints) as a primary end point show statistical treatment significance at week 48 compared to the baseline. The total knee cartilage volume change measured by a semi-automated segmentation method (ITK-SNAP) by two different blinded researchers show significant gain of cartilage in the ReJoin® group but a loss of cartilage in ARTZ@ group, reaching statistical difference between the two groups 48 weeks after therapy. Highlights of the full 48-week follow-up data:
About the ReJoin® Phase IIb trial for KOA The Phase IIb is a randomized, double-blinded to patients and evaluators, and controlled trial, which enrolled 53 patients in multiple clinical centers with a 48-week follow-up duration. The endpoints were WOMAC score, VAS score, SF-36 score and MRI cartilage volume. The trial is conducted in China and registered with the U.S. National Institutes of Health (NIH) under the number NCT02162693 (click here to view). About the ReJoin® Therapy Cellular Biomedicine Group’s ReJoin® therapy for KOA is an interventional therapy that consists of 30ml of adipose (fat) tissue obtained via lipoaspiration from the patient, from which the patient’s vascular stromal cells (VSC; a combination of several types of monocytes including mesenchymal stem cells) are isolated using CBMG’s proprietary medical device, the A-StromalTM Kit, which produces a high yield of VSC, and haMPCs are then expanded using CBMG’s proprietary culture medium, and formulated for ReJoin® therapy using CBMG’s proprietary formulation. After three weeks of cell culture there is an initial injection into the knee joints and a second injection three weeks later. The rest of the patient’s haMPC are banked for potential future use. Some of the special characteristics of ReJoin® regenerative therapy for KOA are:
