– Patient enrollment exceeding expectations – – 14 U.S. sites actively enrolling; 10 U.S. sites added since last update – – Anticipate completing NEXICART-2 clinical trial ahead of schedule – LOS ANGELES, CA, May 23, 2025 (GLOBE NEWSWIRE) -- Immix Biopharma, Inc. (“ImmixBio”, “Company”, “We” or “Us” or "IMMX”), a clinical-stage biopharmaceutical company developing cell therapies for AL Amyloidosis and other serious diseases, today announced that 14 U.S. sites are actively enrolling in U.S. multi-site study NEXICART-2. This milestone adds 10 sites since the Company’s most recent update. The company anticipates completing NEXICART-2 clinical trial ahead of schedule. “Based on robust enrollment and demand, we are proud to expand our NEXICART-2 clinical trial footprint to a significant number of national AL Amyloidosis centers,” said Ilya Rachman, M.D., Ph.D., Chief Executive Officer of Immix Biopharma. Gabriel Morris, Chief Financial Officer of Immix Biopharma, added, “Working with these world-class sites, we believe we are well positioned to complete NEXICART-2 on time or even ahead of schedule.” Phase 1/2 interim readout data from its U.S. NXC-201 NEXICART-2 trial in relapsed/refractory AL Amyloidosis has been selected for oral presentation at the upcoming 2025 American Society of Clinical Oncology Annual Meeting (ASCO 2025) being held in Chicago, Illinois, May 30 – June 3, 2025, presented by lead investigator Heather Landau, M.D., Director of Amyloidosis Program and a Bone Marrow Transplant Specialist & Cellular Therapist at Memorial Sloan-Kettering Cancer Center in New York. About NEXICART-2NEXICART-2 (NCT06097832) is an ongoing single-arm multi-site U.S. Phase 1/2 clinical trial of sterically-optimized CAR-T NXC-201 in relapsed/refractory AL Amyloidosis. NEXICART-2 is expected to enroll 40 patients with preserved heart function (excluding patients with pre-existing heart failure) who have not been exposed to prior BCMA-targeted therapy. The primary endpoint of the Phase 1 portion is safety. The primary endpoint of the Phase 2 portion is efficacy. About NXC-201NXC-201 is a sterically-optimized BCMA-targeted chimeric antigen receptor T (CAR-T) cell therapy with a “digital filter” that filters out non-specific activation. Initial data from ex-U.S. study NEXICART-1 has demonstrated high complete response rates in relapsed/refractory AL Amyloidosis. U.S. Phase 1/2 study NEXICART-2 is ongoing. NXC-201 has been awarded Regenerative Medicine Advanced Therapy (RMAT) by the FDA, and Orphan Drug Designation (ODD) by the US FDA and in the EU by the EMA. About AL AmyloidosisAL amyloidosis is caused by abnormal plasma cells in the bone marrow, which produce misfolded amyloid proteins that circulate in the blood, then build-up in the heart, kidney, liver, and other organs. This build-up causes progressive and widespread organ damage, including heart and renal failure, leading to high mortality rates. The U.S. observed prevalence of relapsed/refractory AL Amyloidosis is estimated to be growing at 12% per year according to Staron, et al Blood Cancer Journal, to approximately 33,277 patients in 2024. The Amyloidosis market was $3.6 billion in 2017, and is expected to reach $6 billion in 2025, according to Grand View Research. About Immix Biopharma, Inc.Immix Biopharma, Inc.
