Cellular Biomedicine Group Presents First Clinical Data of IIT Phase 1 Trial of C-CAR088, a Novel BCMA CAR-T, at the 61st Annual Meeting of the American Society of Hematology

- Five Patients were included in the analysis; all five patients showed clinical improvement in as early as two weeks

NEW YORK, NY, USA and SHANGHAI, China I December 7, 2019 I Cellular Biomedicine Group Inc. (NASDAQ: CBMG) ("CBMG" or the "Company"), a biopharmaceutical firm engaged in the drug development of immunotherapies for cancer and stem cell therapies, announced early data from its ongoing investigator initiated trial ("IIT") at an oral presentation titled "Novel Anti-BCMA CAR-T for Relapsed or Refractory Multiple Myeloma" at the 61st American Society of Hematology ("ASH") annual meeting on December 7, 2019 in Orlando, Florida.

C-CAR088 is a novel anti-B-cell maturation antigen ("BCMA") chimeric antigen receptor T-cell ("CAR-T") product designed to improve efficacy through increasing the specificity and reducing immunogenicity by fusing a single-chain variable fragment ("scFv") from high-affinity human monoclonal antibody to a CD3ζ/4-1BB signaling domain. It can effectively eradicate BCMA positive tumor cells both in vitro and in vivo.

A Phase 1, dose escalation trial is being conducted in patients with relapsed or refractory Multiple Myeloma ("r/r MM") to assess the safety and efficacy of C-CAR088.  As of the end of November the Company has enrolled eleven patients, of which eight were infused with C-CAR088, and five patients were evaluable for clinical response.   Three of the five patients were treated with C-CAR088 at the dose of 1.0 x 106 CAR-T cells/kg, and the other two patients treated at 3.0x106 CAR-T cells/kg. All five patients showed clinical improvement as early as two weeks post treatment. By 4 weeks, one patient achieved a complete response ("CR"), three patients reached a very good partial response ("VGPR"), and one patient reached a partial response ("PR") post C-CAR088 infusion. Furthermore, the Company observed that C-CAR088 proliferation & expansion in the peripheral blood correlated with the decrease of tumor burden in all patients. C-CAR088 treatment showed to be  well tolerated. There were no dose-limiting toxicities ("DLTs").  Reversible Grade 1 and Grade 2 Cytokine release syndrome ("CRS") were observed in four and one patient respectively.

"The early IIT clinical trial results in patients with relapsed and refractory multiple myeloma for C-CAR088 support preclinical findings that C-CAR088 shows promising efficacy and has a manageable safety profile," stated Dr. Yihong Yao, Chief Scientific Officer of CBMG. Dr. Yao added, "The very early clinical efficacy signal at low and suboptimal dosing is encouraging and needs to be confirmed by the ongoing clinical trial. We will continue to  monitor and evaluate the duration of response ("DOR") and to further pursue DOR improvement alternatives."

About Multiple Myeloma 
Multiple Myeloma, a cancer derived from plasma cells, accounts for 1% of all cancers and approximately 10% of all hematological malignancies[1]. It is estimated that there are 27,800 new cases of MM diagnosed in China each year. With the acceleration of the aging process in China, it is predicted that MM, with a rapid growth in incidence, will become one of the more significant diseases that affect people's health in the country[2]. The American Cancer Society estimates that in the United States, approximately 32,110 new cases of MM (18,130 in men and 13,980 in women) will be diagnosed in 2019[3].
