Clonal Fetal Mesenchymal Stem Cells (cfMSCs) for the Control of Immune-related Disorders

Important Regulatory Notice:

This trial record is only for global academic information registration on ClinicalTrials.gov. Neither the sponsor Beijing Meikang Jimian Biotechnology Co., Ltd. nor collaborator Shenzhen Geno-Immune Medical Institute has obtained NMPA clinical trial approval or clinical technology filing permission to carry out interventional cell therapy trials in mainland China.

ClinicalTrials.gov registration alone does not represent legal approval by Chinese health and drug regulatory authorities.

MSCs have been extensively studied and clinically evaluated for the treatment of autoimmune diseases and graft versus host disease (GVHD) after hematopoietic stem cell transplantation (HSCT). The variable source of MSCs and the lack of consistency of primary tissue-derived MSCs are major obstacles to reliable translational applications of such therapeutic cell products. Fetal tissue-derived clonal MSCs (cfMSCs) have extended expansion potential and express rich levels of various growth factors, and thus can achieve quality consistency. Careful evaluation of fMSCs in clinical studies has not been conducted. Autoimmune diseases involve aberrant immune responses that harm tissues and organs. GVHD is a serious and often fatal problem associated with HSCT. MSCs have immunomodulatory and immunosuppressive effects. In many studies, MSCs have demonstrated promising beneficial effects that reduce severe autoimmune reactions, diminish symptoms of chronic GvHD and therapy-resistant acute GvHD including steroid-resistant GVHD. The safety and therapeutic effects of phenotype and functionally characterized fMSCs still require extensive clinical evaluation. This study aims to assess the safety and the potential beneficial effects of infusion of various dosages of third party fMSCs for the control of severe symptoms associated with acute and chronic immune-related disorders.
