On track to dose relapsed/refractory AL Amyloidosis patients with CAR-T NXC-201 at New York City lead site and other leading U.S. sites mid-2024

No change in patient enrollment timing

LOS ANGELES, April 18, 2024 (GLOBE NEWSWIRE) -- Nexcella, an Immix Biopharma, Inc. subsidiary (Nasdaq: IMMX) (“ImmixBio”, “Company”, “We” or “Us” or “IMMX”), a clinical-stage biopharmaceutical company trailblazing cell therapies in AL Amyloidosis and other autoimmune diseases, today announced that it is on track to dose NXC-201 patients in the U.S. with no change in patient enrollment timing.

“We are on track to dose relapsed/refractory AL Amyloidosis NXC-201 patients at our New York City lead site and other leading U.S. sites in mid-2024. U.S. site clinical trial agreements have been signed, and site initiation visits are being scheduled,” said Ilya Rachman, MD PhD CEO of Immix Biopharma and Executive Chairman of Nexcella. “Building on our existing NXC-201 clinical dataset, our U.S. relapsed/refractory AL Amyloidosis clinical trial design is focused on patients with adequate cardiac function who are most likely to experience the greatest clinical benefit from NXC-201. We are committed to providing additional treatment alternatives for relapsed/refractory AL Amyloidosis patients, where there are no FDA approved drugs today.”

About NEXICART-2

NEXICART-2 (NCT06097832) is an open-label, single-arm, multi-site Phase 1b dose expansion clinical trial in relapsed/refractory AL Amyloidosis for CAR-T NXC-201 in the United States. NEXICART-2 is expected to enroll 40 patients with adequate cardiac function over a period of approximately 18 months from first patient dosing. The objectives are the safety and efficacy of NXC-201. The expected primary endpoints are complete response rate and overall response rate according to consensus recommendations (Palladini et al. 2012).

About NXC-201

We believe NXC-201 (formerly HBI0101) is the only “Single-Day CRS” BCMA-targeted CAR-T cell therapy that is uniquely suited to target AL Amyloidosis and other autoimmune diseases. It is being studied in a comprehensive clinical development program for the treatment of patients with relapsed/refractory AL amyloidosis, and expanding into other autoimmune indications. These trials build on a robust NXC-201 clinical dataset initiated in February 2021. NXC-201 has been awarded Orphan Drug Designation (ODD) by the FDA in both AL Amyloidosis and multiple myeloma, and awarded EU ODD by the EMA in AL Amyloidosis.
