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
Rhea-AI Summary
Immix Biopharma (NASDAQ:IMMX) reported positive Phase 2 results for NXC-201 at ASH 2025 with an independent review committee complete response (CR) rate of 75% (15/20) at s/u IFE(-).
MRD negativity in bone marrow was observed in 4 of 5 pending patients, which the company says could raise the CR to 95%. Downstream organ responses occurred in 70% of evaluable patients (7/10). No neurotoxicity and only low-grade cytokine release syndrome (median duration 1 day) were reported. NEXICART-2 final readout and planned BLA submission in 2026. Data cutoff: Nov 13, 2025.
Positive

- No observed neurotoxicity; CRS median duration 1 day
Negative
- Small Phase 2 cohort: 20 patients, limiting statistical certainty
- Five patients pending assessment introduce near-term outcome uncertainty
- Median prior lines of therapy 4 (range 1-10) could affect generalizability

Clinical/conference news has often produced mixed or contrary price reactions, with several positive updates followed by negative or flat moves.
Over the past months, Immix Biopharma has repeatedly highlighted NXC-201’s progress in relapsed/refractory AL amyloidosis. Key steps included multiple conference appearances at ASCO 2025 and ASH 2025, and a November 2025 announcement appointing a Chief Commercial Officer to prepare for NXC-201’s launch. Earlier clinical updates showed strong complete response rates and expanding trial activity. Today’s Phase 2 ASH data and 2026 BLA plan build directly on those prior efficacy and development milestones.
Regulatory & Risk Context
IMMX filed a Form S-3 shelf registration on 2025-10-06. The excerpted filing highlights holders, offering-related expenses, and indemnification provisions. The record provided does not disclose the shelf size, and no usage has been recorded yet (usage count 0).
Market Pulse Summary
The stock surged +10.6% in the session following this news. A strong positive reaction aligns with the notably high 75% complete response rate and favorable safety profile reported at ASH 2025. The move exceeds the average 6.49% reaction seen in prior clinical updates, suggesting investors weighed this dataset as especially meaningful. However, an active Form S-3 shelf and prior financing activity highlight ongoing capital needs that could influence future trading dynamics.

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.
