LOS ANGELES, Sept. 29, 2026 (GLOBE NEWSWIRE) -- Immix Biopharma, Inc. (“ImmixBio”, “Company”, “We” or “Us” or “IMMX”), a global leader in relapsed/refractory AL Amyloidosis, today announced positive results of an 89% (40/45) complete response (CR) rate in an interim update across all forty-five NEXICART-2 patients, advancing NXC-201 as a potential best-in-class therapy for AL Amyloidosis. All twenty-five new relapsed/refractory AL Amyloidosis patients are either in complete response (CR) or already minimum residual disease (MRD)-negative. To-date, all patients achieving MRD-negativity reached CR within one year of treatment. Across all forty-five patients, NXC-201 produced an 89% (40/45) CR rate as assessed by independent review committee. In four pending patients that are already MRD-negative, MRD-negativity in bone marrow predicts future CR, potentially increasing future CR rate up to 98% (44/45). No relapses to date have been observed for any patient who reached CR or MRD-negativity to-date. No neurotoxicity or enterocolitis has been observed to-date. NEXICART-2 final readout and BLA submission are planned in 2027.
“Today, patients with AL Amyloidosis face years of burdensome, continuous treatment. As a potential one-and-done treatment option, NXC-201 could liberate patients from that burden,” said Ilya Rachman, MD, PhD, Chief Executive Officer of Immix Biopharma, adding: “We are thrilled with NXC-201’s magnitude of effect across a broad range of relapsed/refractory AL Amyloidosis patients in NEXICART-2.” Gabriel Morris, President of Immix Biopharma, added, “NXC-201’s complete response rate continues to increase over time, even as reported patient counts have now more than doubled. We look forward to final readout, BLA submission and potentially making NXC-201 available to relapsed/refractory AL Amyloidosis patients at commercial launch.”

About NEXICART-2
NEXICART-2 (NCT06097832) is a 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 a 45-patient study.
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 30,506 patients in 2026.
The Amyloidosis market was $6.2 billion in 2025, and is expected to reach $6.6 billion in 2026, 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 proprietary CD3ζ, CD8 hinge and binder “digital filter” 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.
