Rhea-AI Filing Summary

Immix Biopharma reported interim Phase 2 NEXICART-2 data showing a 95% complete response (CR) rate, with 19 of the first 20 relapsed/refractory AL amyloidosis patients treated with CAR-T candidate NXC-201 achieving CR.

All minimal residual disease (MRD)-negative patients converted to CR, and all CRs occurred within one year of follow-up, with no relapses observed so far among CR patients. Seventeen of 20 patients showed rapid normalization of diseased light chains, with a median time to initial response of 7 days, and MRD-negativity at 10-5 was reached within 30 days for all MRD-negative patients.

NEXICART-2 is a fully enrolled 45-patient, multi-site U.S. Phase 2 trial with a potentially registrational design, and the next data update is expected in late September 2026. The company also plans a multi-center, randomized Phase 3 trial in newly diagnosed AL amyloidosis patients, targeted to start in the first half of 2027.

Positive

  • Strong interim efficacy: NEXICART-2 reports a 95% complete response rate (19 of 20 relapsed/refractory AL amyloidosis patients), with all MRD-negative patients converting to complete response and no relapses observed so far among responders.

Negative

  • None.

Insights

Interim NXC-201 data show very high response rates but remain early.

The company reports a 95% complete response rate in the first 20 NEXICART-2 patients, with all MRD-negative patients converting to complete response within one year and no relapses among responders so far. Rapid light-chain normalization suggests strong early disease control.

These data underpin plans for a potentially registrational Phase 2 design and a randomized Phase 3 in newly diagnosed AL amyloidosis from H1 2027. However, the company explicitly stresses that these are interim results and that final outcomes and regulatory interpretations may differ, which is typical for mid-stage oncology programs.

Future disclosures, including the planned late-September 2026 update and the one-year follow-up data expected by March 2027, will clarify durability, safety and the basis for a potential BLA submission for NXC-201 in AL amyloidosis.

complete response medical
"all four MRD-negative relapsed/refractory AL Amyloidosis patients ... have converted to complete response (CR)"
A complete response is a positive outcome in which a company’s efforts to address issues or questions fully resolve the problem, often meaning that no further action or investigation is needed. For investors, it signals that concerns have been thoroughly addressed, which can boost confidence in the company's stability or decision-making. Think of it like a doctor fully treating an illness, leaving no remaining symptoms.
MRD-negative medical
"all four MRD-negative relapsed/refractory AL Amyloidosis patients ... have converted to CR"
MRD-negative describes a test result showing no detectable leftover cancer cells after treatment using very sensitive laboratory methods; it means the disease is below the test’s limit of detection. For investors, an MRD-negative result is a strong signal that a therapy is working and the patient’s relapse risk is lower, which can improve prospects for regulatory approval, wider use, and long-term commercial value — like finding no footprints after clearing a garden of weeds.
sterically-optimized CAR-T medical
"Phase 2 clinical trial of sterically-optimized CAR-T NXC-201 in relapsed/refractory AL Amyloidosis"
Breakthrough Therapy Designation regulatory
"NXC-201 has been awarded Breakthrough Therapy Designation (BTD) and Regenerative Medicine Advanced Therapy (RMAT)"
A breakthrough therapy designation is a regulatory fast-track given to a drug or treatment that shows early signs of providing a major improvement over existing options for a serious condition. Think of it as a VIP lane that can speed up development and more intensive guidance from regulators, which matters to investors because it can shorten time to market, reduce development risk and potentially increase a company’s value — though it does not guarantee approval.
Regenerative Medicine Advanced Therapy regulatory
"NXC-201 has been awarded Breakthrough Therapy Designation (BTD) and Regenerative Medicine Advanced Therapy (RMAT)"
Regenerative Medicine Advanced Therapy (RMAT) is a U.S. regulatory designation for cell, gene, and tissue‑based therapies intended to treat serious or life‑threatening conditions; it gives developers a “fast lane” with more frequent agency interaction and eligibility for accelerated review pathways. For investors, an RMAT label signals that a therapy may reach market faster and face less regulatory uncertainty than a standard program, which can raise the potential value and reduce timeline risk—though it is not a guarantee of approval.
Orphan Drug Designation regulatory
"NXC-201 has been awarded ... Orphan Drug Designation (ODD) by the US FDA and in the EU"
Orphan drug designation is a special status given to medicines developed to treat rare diseases affecting only a small number of people. This status often provides benefits like faster approval processes and financial incentives, making it more attractive for companies to develop these drugs. For investors, it signals potential for exclusive market rights and reduced competition, which can impact the drug’s profitability.

Immix Biopharma Announces 95% complete response rate in interim update from relapsed/refractory AL Amyloidosis Clinical Trial NEXICART-2

 

– 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 –

 

– All subsequently enrolled patients for whom MRD results are available are MRD-negative at one month –

 

– Next NEXICART-2 Update Expected Late September, 2026 –

 

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 5th 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.”
