(the “Company”) issued a press release announcing 20-patient safety and efficacy data from NEXICART-2, the first U.S. trial of CAR-T in relapsed/refractory light chain (AL) amyloidosis, NXC-201. The press release follows the December 7, 2025 presentation of such results at the American Society of Hematology 2025 Annual Meeting (ASH 2025) held in Orlando, Florida. A copy of the press release is attached as Exhibit 99.1.
In accordance with General Instruction B.2 of Form 8-K, the information in Item 7.01 of this Current Report on Form 8-K 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.

Item 8.01 Other Events.
On December 7, 2025, the Company announced positive phase 2 NXC-201 results in an oral presentation at the American Society of Hematology’s ASH 2025 Annual Meeting, presented by Heather Landau, MD, of Memorial Sloan Kettering Cancer Center. NXC-201 demonstrated a complete response (CR) rate of 75% (at s/u IFE(-) level) (15/20) by independent review committee.
ASH Presentation Results
Prior to NXC-201 treatment, all patients were exposed to an anti-CD38 antibody and a proteasome inhibitor. Median prior lines of therapy was 4 (range: 1-10). All patients had baseline relapsed/refractory AL Amyloidosis organ involvement. After NXC-201 treatment, complete responses (CRs) were observed in 75% (15 out of 20) patients. In four out of five pending patients, minimum residual disease (MRD) negativity in bone marrow suggests a future complete response may be expected. Downstream clinical improvement, including organ responses, were observed in 70% of evaluable patients (7/10). No neurotoxicity has been observed. Grade 2 cytokine release syndrome was observed in four patients, Grade 1 cytokine release syndrome was observed in 11 patients, with a median duration of 1 day. The ASH presentation contains clinical data as of November 13, 2025.

Forward-Looking Statements
This report and Exhibit 99.1 hereto contains certain forward-looking statements that involve risks and uncertainties that could cause actual results to be materially different from historical results or from any future results expressed or implied by such forward-looking statements. Such forward-looking statements include statements regarding, among other things, the potential benefits of our product candidate CAR-T NXC-201 and the timing and results related to clinical trials, and planned regulatory submissions. These statements involve risks and uncertainties, and actual results may differ materially from any future results expressed or implied by the forward-looking statements. Forward-looking statements also include, but are not limited to, our plans, objectives, expectations and intentions and other statements that contain words such as “expects”, “contemplates”, “anticipates”, “plans”, “intends”, “believes”, “estimates”, “potential”, and variations of such words or similar expressions that convey the uncertainty of future events or outcomes, or that do not relate to historical matters. Those forward-looking statements involve known and unknown risks, uncertainties and other factors that could cause actual results to differ materially. Among those factors are: (i) the risk that the further data from the ongoing Phase 1/2 clinical trials for CAR-T NXC-201 will not be favorably consistent with the data readouts to date, (ii) the risk that the Company may not be able to continue the NEXICART-2 multi-site U.S. Phase 1/2 clinical trial; (iii) the risk that the Company may not be able to advance to registration-enabling studies for CAR-T NXC-201 or other product candidates, (iv) that success in early phases of pre-clinical and clinicals trials do not ensure later clinical trials will be successful; (v) that no drug product developed by the Company has received FDA pre-market approval or otherwise been incorporated into a commercial drug product, (vi) the risk that the Company may not be able to obtain additional working capital with which to continue the clinical trials for CAR-T NXC-201, or advance to the initiation of registration-enabling studies, for such product candidates as and when needed and (vii) those other risks disclosed in the section “Risk Factors” included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on March 25, 2025 and other periodic or current reports subsequently filed with the SEC.

At ASH 2025 Oral Presentation, Immix Biopharma Reports Positive Phase 2 NXC-201 Results, Advancing Toward BLA Submission as a Potentially First- and Best-in-Class Therapy for relapsed/refractory AL Amyloidosis
– NXC-201 demonstrated a complete response (CR) rate of 75% (15/20) (at s/u IFE(-) level) by independent review committee –
– In four out of five pending patients, MRD negativity in bone marrow predicts future complete response, potentially increasing future CR rate to 95% –
– NEXICART-2 final readout and BLA submission planned in 2026 –
LOS ANGELES, December 7, 2025 (GLOBE NEWSWIRE) – Immix Biopharma, Inc. (“ImmixBio”, “Company”, “We” or “Us” or “IMMX”), a global leader in relapsed/refractory AL Amyloidosis, today announced positive phase 2 NXC-201 results in an oral presentation at ASH 2025 presented by Heather Landau, MD, of Memorial Sloan Kettering Cancer Center. NXC-201 demonstrated a complete response (CR) rate of 75% (15/20) (at s/u IFE(-) level) by independent review committee. In four out of five pending patients, MRD negativity in bone marrow predicts future complete response, potentially increasing future CR rate to 95%. NEXICART-2 final readout and BLA submission are planned for 2026.
“In the larger patient set Phase 2 results presented today at ASH, we are thrilled to see complete response rates continue to improve in NEXICART-2. These excellent results demonstrate the potential of NXC-201 to address the significant unmet medical need in relapsed/refractory AL Amyloidosis,” said Ilya Rachman, MD, PhD, Chief Executive Officer of Immix Biopharma. Gabriel Morris, Chief Financial Officer of Immix Biopharma, added “This exciting Phase 2 milestone brings us one step closer to delivering this promising therapy to patients upon planned BLA submission in 2026.”
ASH Presentation Results – Phase 2
Prior to NXC-201 treatment, all patients were exposed to an anti-CD38 antibody and a proteasome inhibitor. Median prior lines of therapy was 4 (range: 1-10). All patients had baseline relapsed/refractory AL Amyloidosis organ involvement. After NXC-201 treatment, complete responses (CRs) were observed in 75% (15 out of 20 patients) (at s/u IFE(-) level) by independent review committee. In four out of five pending patients, minimum residual disease (MRD) negativity in bone marrow predicts future complete response, potentially increasing the future CR rate to 95%. Downstream clinical improvement, including organ responses, were observed in 70% of evaluable patients (7/10). No neurotoxicity was observed. Only low-grade cytokine release syndrome has been observed with a median duration of 1 day. The ASH presentation contains clinical data as of November 13, 2025.

Current treatments typically result in a 10% or lower complete response (CR) rate in relapsed/refractory AL Amyloidosis according to Zanwar, et al 2024, indicating a high unmet medical need.

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 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 Regenerative Medicine Advanced Therapy (RMAT) by the FDA, and Orphan Drug Designation (ODD) by the US FDA and in the EU by the EMA.
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.
