**Item 7.01 Regulation FD Disclosure.**

On May 21, 2026, Immix Biopharma, Inc. (the "Company") issued a press release announcing that all four MRD-negative relapsed/refractory light chain ("AL") Amyloidosis patients announced by the Company at the American Society of Hematology 2025 Annual Meeting ("ASH 2025") held in Orlando, Florida in December have converted to complete response ("CR"). 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, 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 May 21, 2026, the Company announced an update from the Phase 2 NEXICART-2 NXC-201 clinical trial, including that all four MRD-negative relapsed/refractory AL Amyloidosis patients announced by the Company at the ASH 2025 have converted to CR. Of the first 20 patients in NEXICART-2, all MRD-negative patients have converted to CR, increasing the CR rate to 95% (19/20). No relapses have been observed to date for patients who have reached CR, and all CRs were reached within one year of follow-up post-dosing. Additionally, MRD-negativity 10<sup>-5</sup> was achieved within 30 days for all MRD-negative patients. As of May 14, 2025, 17 of 20 patients in NEXICART-2 showed rapid normalization of diseased light chains in patients with a median time to initial response of 7 days. Safety data through May 14, 2026 has been generally consistent with previous safety data observed and reported in NEXICART-2 trial. The next NEXICART-2 update is expected in late September 2026. NEXICART-2 is a fully enrolled 45-patient multi-site U.S. Phase 2 clinical trial of sterically-optimized CAR-T NXC-201 in relapsed/refractory AL Amyloidosis, with a potentially registrational design. A multi-center, randomized, Phase 3 trial of NXC-201 in newly diagnosed AL Amyloidosis patients is planned to be initiated in the first half of 2027.

**Risk Factors**

The risk factor listed below should be read in conjunction with the risk factors disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

***Interim data from clinical trials are subject to various risks, including that final results may be materially different than those reflected in any interim data and that third parties, including regulatory agencies may disagree with the analysis used to interpret the interim data.***

Interim data from clinical trials are subject to the risk that one or more of the clinical outcomes may materially change as more data on existing patients become available. When a clinical trial is ongoing, the final results from the trial may be materially different from those reflected in any interim data the Company reports.

Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or product and the value of the Company in general. In addition, the information the Company chooses to publicly disclose regarding a particular study or clinical trial is typically a summary of extensive information, and you or others may not agree with what the Company determines is the material or otherwise appropriate information to include in its disclosure. Any information the Company determines not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise regarding a particular product, product candidate or its business. If the interim data that the Company reports differs from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, the Company's ability to obtain approval for, and commercialize, its product candidates, including NXC-201, may be harmed.

*– Of first 20 patients, all four MRD-negative patients have converted to complete response (CR) –*

 

– *CR rate now 95% (19 of 20 patients) –*

 

*– All CRs reached within 1 year of follow-up post-dosing –*

*– No relapses to-date observed for patients who have reached CR –*

LOS ANGELES, May 21, 2026 (GLOBE NEWSWIRE) – Immix Biopharma, Inc. ("ImmixBio", "Company", "We" or "Us" or "IMMX"), a global leader in AL Amyloidosis, today announced that all four relapsed/refractory AL Amyloidosis MRD-negative patients presented at ASH 2025 have converted to complete response (CR). The NEXICART-2 CR rate is now 95% (19 out of 20 patients). All CRs were reached within 1 year of follow-up post-dosing. No relapses have been observed as of today for patients who have reached CR. All subsequently enrolled patients for whom MRD results are available are MRD-negative at one month. The next NEXICART-2 update is expected late September 2026.

These results support the Company's plan to initiate a multi-center, randomized Phase 3 trial in newly diagnosed AL Amyloidosis patients.

"Even in a heavily pretreated population of median 4 prior lines of therapy, we are pleased that NXC-201, as a 5<sup>th</sup> line of therapy, drives MRD-negativity, converting to durable CRs to-date, indicating that NXC-201 can eliminate the source of toxic light chains that clog up the heart, kidney and liver, causing organ failure and death in relapsed/refractory AL Amyloidosis. As a potential frontline therapy in AL Amyloidosis, we believe there's potential to transform a usual 2-year treatment, into a one-and-done: NXC-201." Gabriel Morris, President, Chief Financial Officer of Immix Biopharma, added, "We have observed the NEXICART-2 CR rate improving over time. In September 2026 we plan to present updated data from our ongoing NEXICART-2 trial. By end of March 2027, we expect to present 1-year follow-up data of enrolled patients, which we expect will drive BLA submission and 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 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 as of 2023.

**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.
