(“ImmixBio”, “Company”, “We” or “Us” or ”IMMX”), a clinical-stage biopharmaceutical company pioneering personalized therapies for oncology and immunology, today announced new clinical data from its Phase 1b/2a NEXICART-1 (NCT04720313) study of novel, autologous, BCMA-targeted chimeric antigen receptor T (CAR-T) cell therapy, NXC-201, in patients with relapsed/refractory AL Amyloidosis (R/R ALA) at an oral presentation by study investigator Moshe E. Gatt, MD at the 65th American Society of Hematology (ASH) Meeting being held in San Diego, CA. The updated results include follow-up and clinical data from one new patient. All patients were relapsed/refractory to standard-of-care Dara-CyBorD (daratumumab combined with cyclophosphamide, bortezomib, and dexamethasone) and had experienced a median of 6 prior lines of therapy that failed to stop worsening of disease prior to receiving NXC-201. “There is a rising prevalence of relapsed/refractory AL Amyloidosis patients who have no approved options for treatment,” said Polina Stepensky, M.D., Director of the Hadassah Medical Organization’s Department of Bone Marrow Transplantation and Immunotherapy for Adults and Children, and principal study investigator. “We continue to be encouraged by NXC-201’s 100% overall response rate, including in this 10th relapsed/refractory AL amyloidosis patient.” “We believe NXC-201 is the first and only CAR-T in clinical development for AL amyloidosis. With our recent IND clearance, we are thrilled to be now activating sites to bring this first-of-a-kind study to U.S. relapsed/refractory AL Amyloidosis patients,” said Ilya Rachman, M.D., Ph.D., Chief Executive Officer of Immix Biopharma.
