IMMIX BIOPHARMA

(Nasdaq: IMMX)

The Global Leader in Relapsed/Refractory AL Amyloidosis

Immix Biopharma is working to overcome one of the most significant barriers to widespread CAR-T adoption: neurotoxicity. By addressing this challenge, ImmixBio aims to unlock access to CAR-T therapies in indications previously out of reach—beginning with AL Amyloidosis—and in settings where CAR-T was not previously feasible, such as the 95% of U.S. medical centers currently unable to administer these treatments.

Our Strategy Is To

Build on the proliferation of cell therapy expertise across the U.S. to deliver FDA approval submissions in AL amyloidosis and other serious diseases for NXC-201, our highly differentiated cell therapy candidate.

Demonstrate the power of overcoming neurotoxicity, divorcing the classical relationship between toxicity and efficacy.

Continue to expand into new indications and advance new cell therapies with similar transformative potential.

Key Reasons to Watch

Lead Program Advancing in U.S. Trials: NXC-201 is currently being evaluated in the NEXICART-2 clinical trial at leading institutions including Memorial Sloan Kettering Cancer Center.
Regulatory Momentum: FDA approval of the IND application for NXC-201 allows U.S. patient dosing and opens potential pathways into additional indications.
Differentiated CAR-T Profile: NXC-201 has demonstrated a favorable tolerability profile in clinical trials, supporting the potential to address diseases historically underserved by CAR-T therapies.
Scientific Leadership: ImmixBio has added recognized experts from top institutions to its Scientific Advisory Board, strengthening its clinical development strategy.
Scalable Platform Potential: The company’s N-GENIUS™ Cell Therapy Platform may support the development of additional therapies targeting other serious diseases.

*NXC-201 is an investigational therapy. Safety and efficacy have not been established.

Immix Biopharma Announces 50% Enrollment Milestone Surpassed in its ongoing relapsed/refractory AL Amyloidosis Clinical Trial, NEXICART-2

– On track for first FDA Biologics License Application (BLA) approved cell therapy in orphan indication relapsed/refractory AL Amyloidosis –

Los Angeles, CA, Sept. 18, 2025 (GLOBE NEWSWIRE) — Immix Biopharma, Inc. (“ImmixBio”, “Company”, “We” or “Us” or “IMMX”), a clinical-stage biopharmaceutical company developing cell therapies for AL Amyloidosis and other serious diseases, today announced that 50% enrollment milestone has already been surpassed in NEXICART-2, its relapsed/refractory AL Amyloidosis clinical trial of sterically-optimized CAR-T NXC-201. Immix continues to enroll expediently toward BLA submission.

“With excitement generated by our clinical results presented at ASCO, surpassing 50% enrollment in

NEXICART-2 demonstrates the growing interest among relapsed/refractory AL Amyloidosis clinicians and patients, where no drugs are FDA approved today,” said Ilya Rachman, M.D., Ph.D., Chief Executive Officer of Immix Biopharma. Gabriel Morris, Chief Financial Officer of Immix Biopharma, added, “Growing excitement accelerates NEXICART-2 BLA submission for FDA approval, and supports future commercial awareness.”

NEXICART-2 interim results were presented at the American Society for Clinical Oncology (ASCO 2025) by Heather Landau, MD of Memorial Sloan Kettering Cancer Center and can be accessed on the Company’s website under publications (ASCO Post article and video, MSKCC article, Cleveland Clinic article). A webcast of the Company’s Key Opinion Leader (KOL) event to discuss the NXC-201 ASCO 2025 interim results can be accessed here.

Immix Biopharma, Inc. (Nasdaq: IMMX) is a clinical-stage biopharmaceutical company focused on advancing innovative cell therapies. The company’s lead candidate, NXC-201, is a proprietary BCMA-targeted CAR-T therapy being evaluated for relapsed/refractory AL Amyloidosis.

NXC-201 is currently in a U.S.-based Phase 1b/2a study (NEXICART-2, NCT06097832), conducted at more than a dozen centers including Memorial Sloan Kettering Cancer Center. Initial clinical results were featured in an oral presentation at ASCO 2025 by Dr. Heather Landau of MSKCC.

The therapy has been granted Regenerative Medicine Advanced Therapy (RMAT) designation by the FDA and Orphan Drug Designation (ODD) in both the United States and the European Union.

Market Opportunity

Relapsed/Refractory AL Amyloidosis:

No FDA-approved therapies currently available
Represents a significant unmet medical need
Estimated to be a $3B+ global market opportunity
Cell therapy may offer a new therapeutic pathway if proven safe and effective

What Is NXC-201 CAR-T Therapy?

An Investigational Approach to Cell-Based Immunotherapy

Our immune systems are designed to detect and eliminate harmful cells. However, certain diseases like AL Amyloidosis originate from the body’s own cells and may avoid detection by the immune system.

NXC-201 is an investigational BCMA-targeted CAR-T (chimeric antigen receptor T-cell) therapy designed to address this challenge. The therapy involves collecting a patient’s own T cells and genetically modifying them using proprietary technology developed by Immix Biopharma. These modified cells—NXC-201 CAR-T cells—are then reintroduced into the patient’s body, where they are intended to recognize and engage cells expressing BCMA, a protein found on certain diseased cells.

In a clinical trial setting, NXC-201 is being evaluated in patients with relapsed/refractory AL Amyloidosis. Preliminary data from early trial cohorts have shown encouraging signals, including an overall response rate (ORR) of up to 92% in patients with relapsed/refractory AL Amyloidosis. However, these results are from ongoing studies and may not predict outcomes in future participants.

NXC-201 is an investigational product. It has not been approved by the FDA or any regulatory authority. Safety and efficacy have not been established.
