About Immix Biopharma, Inc.

Immix Biopharma, Inc. (ImmixBio) (Nasdaq: IMMX) is a global leader in AL Amyloidosis. AL Amyloidosis is a devastating disease where the immune system, that's supposed to protect, instead produces toxic light chains, clogging up the heart, kidney and liver, causing organ failure and death. Our lead candidate is sterically-optimized BCMA-targeted chimeric antigen receptor T (CAR-T) cell therapy NXC-201 with a "digital filter" that is designed to filter out non-specific activation. NXC-201 teaches the immune system to recognize and eliminate the source of the toxic light chains. NXC-201 is being evaluated in the U.S. multi-center study for relapsed/refractory AL Amyloidosis NEXICART-2 (NCT06097832), with a potentially registrational design. NXC-201 has been awarded Breakthrough Therapy Designation (BTD) and Regenerative Medicine Advanced Therapy (RMAT) by the US FDA and Orphan Drug Designation (ODD) by FDA and in the EU by the EMA.
