Per FDA, Breakthrough Therapy designation aims to expedite the development and review of drugs that are intended to treat a serious condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapy on a clinically significant endpoint.
The FDA Breakthrough Therapy designation is based on Phase 2 NXC-201 interim clinical results from the NEXICART-2 clinical trial, presented December 7, 2025 in an oral presentation at the American Society of Hematology (ASH) (Free ASH Whitepaper) annual meeting in Orlando, FL.
"We are grateful to FDA for recognizing NXC-201 as the only granted FDA Breakthrough Designation for a therapy in active development in relapsed/refractory AL Amyloidosis, where no approved therapies exist for patients today," said Ilya Rachman, MD, PhD, Chief Executive Officer of Immix Biopharma. Gabriel Morris, Chief Financial Officer of Immix Biopharma, added, "We are looking forward to completing enrollment of NEXICART-2 with the goal of delivering this promising therapy to patients upon planned BLA submission this year."
About NEXICART-2
NEXICART-2 (NCT06097832) is an ongoing multi-site U.S. Phase 2 clinical trial of sterically-optimized CAR-T NXC-201 in relapsed/refractory AL Amyloidosis, with a registrational design. NEXICART-2 is expected to enroll 40 patients.
About AL Amyloidosis
AL amyloidosis is a devastating disease where the immune system, that’s supposed to protect, instead continuously produces toxic light chains, clogging up the heart, kidney and liver, causing organ failure and death.
The number of patients in the U.S. with relapsed/refractory AL Amyloidosis is estimated to be growing at 12% per year according to Staron, et al Blood Cancer Journal, to approximately 38,500 patients in 2026.
The Amyloidosis market was $3.6 billion in 2017, and is expected to reach $6 billion in 2025, according to Grand View Research.
About NXC-201
NXC-201 is a sterically-optimized BCMA-targeted chimeric antigen receptor T (CAR-T) cell therapy 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 has been awarded Breakthrough Therapy Designation (BTD) and Regenerative Medicine Advanced Therapy (RMAT) by the FDA, and Orphan Drug Designation (ODD) by the US FDA and in the EU by the EMA.
