Item 7.01 Regulation FD Disclosure.
On September 29, 2026, Immix Biopharma, Inc. (the “Company”) issued a press release announcing that across all forty-five relapsed/refractory light chain (“AL”) Amyloidosis patients enrolled in the Phase 2 NEXICART-2 clinical trial, NXC-201 has produced an 89% (40/45) complete response (“CR”) rate. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K (this “Current Report”).
In accordance with General Instruction B.2 of Form 8-K, the information in Item 7.01 of this Current Report and Exhibit 99.1 attached hereto shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liability of that section, and shall not be incorporated by reference into any registration statement or other document filed under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, except as shall be expressly set forth by specific reference in such filing. In addition, the information set forth under this Item 7.01, including Exhibit 99.1, shall not be deemed an admission as to the materiality of any information in this Current Report.
Item 8.01 Other Events.
On September 29, 2026, the Company announced an update from the Phase 2 NEXICART-2 clinical trial, including positive results of an 89% (40/45) complete response (“CR”) rate across all forty-five relapsed/refractory AL Amyloidosis patients enrolled in the trial, as assessed by an independent review committee. Additionally, all twenty-five of the new relapsed/refractory AL Amyloidosis patients are either in CR or already minimum residual disease (“MRD”)- negative. To-date, all patients achieving MRD-negativity reached CR within one year of treatment. 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 have been observed to date for patients who reached CR or MRD-negativity. No neurotoxicity or enterocolitis has been observed to date. Safety data through August 4, 2026 has been generally consistent with previous safety data observed and reported in NEXICART-2 trial. NEXICART-2 is a fully enrolled, 45-patient multi-site U.S. Phase 2 clinical trial of sterically-optimized CAR-T NXC-201 in patients with relapsed/refractory AL Amyloidosis, with a registrational design. The NEXICART-2 final readout and BLA submission are planned in mid-2027.

ANGELES, Sep 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.
“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 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
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.
