Nexcella, an Immix Biopharma Subsidiary, Announces New Positive NXC-201 Clinical Data Demonstrating 100% Complete Responses in AL Amyloidosis Patients + Additional Positive Multiple Myeloma Safety Data Demonstrating NXC-201 Outpatient CAR-T Treatment Potential
Nexcella, a subsidiary of Immix Biopharma (IMMX), announced promising results for NXC-201, a CAR-T therapy targeting relapsed/refractory multiple myeloma and AL amyloidosis. The treatment has shown a 100% complete hematologic response and a 100% organ response rate in 8 AL amyloidosis patients. A total of 58 patients have been treated, with notable safety data confirming outpatient treatment potential. The $13.9 billion multiple myeloma market is projected to grow to $28.7 billion by 2027, while the amyloidosis market is expected to reach $6 billion by 2025, according to industry research.
- 100% complete hematologic response in 8 AL amyloidosis patients.
- 100% organ response rate (cardiac, renal, liver) in AL amyloidosis patients.
- 90% overall response rate in multiple myeloma patients.
- Positive safety profile suggests potential for outpatient CAR-T treatments.
- None.

About NXC-201
NXC-201 (formerly HBI0101) is a BCMA-targeted investigational chimeric antigen receptor T (CAR-T) cell therapy that is being studied in a comprehensive clinical development program for the treatment of patients with relapsed or refractory multiple myeloma and AL amyloidosis. The design consists of a structurally differentiated CAR-T with our proprietary BCMA-targeting CAR which has demonstrated reduced toxicity in NEXICART-1, supporting investigating NXC-201 as an outpatient therapy.
As of the October 23, 2022 data cutoff, updated clinical data in 47 patients from the ongoing Phase 1b/2a portion of the NEXICART-1 (NCT04720313) study of the novel, autologous, BCMA-targeted chimeric antigen receptor T (CAR-T) cell therapy NXC-201 for the treatment of relapsed or refractory multiple myeloma and light chain amyloidosis (AL) showed:
- Multiple Myeloma –
90% overall response rate (59% complete responses) for NXC-201 at the therapeutic dose in an ongoing 42-Patient Phase 1 expansion trial (Haematologica https://doi.org/10.3324/haematol.2022.281628, 5th European CAR-T cell meeting https://www.nexcella.com/publications/) in relapsed/refractory multiple myeloma. All patients treated with NXC-201 were triple-class refractory (to at least 1 immunomodulatory drug, 1 proteasome inhibitor and 1 anti-CD38 antibody). - Additional data in 2023 demonstrated outpatient CAR-T treatment potential: cytokine release syndrome (CRS) median onset day zero; median CRS duration 1 day; no grade 4 CRS; only 1 grade 3 CRS across 42 relapsed/refractory multiple myeloma patients.
- The expected primary endpoint for a pivotal study of NXC-201 in relapsed/refractory multiple myeloma is overall response rate.
- AL Amyloidosis –
100% organ response rate (cardiac, renal, liver),100% complete hematologic responses (MRD negativity 10-5), for NXC-201 in 8 relapsed/refractory AL Amyloidosis patients, of which the initial cohort was presented at the 5th European CAR-T cell meeting https://www.nexcella.com/publications/, and published in Clinical Cancer Research https://doi.org/10.1158/1078-0432.CCR-22-0637. - The expected primary endpoint for a pivotal study of NXC-201 in relapsed/refractory AL Amyloidosis is overall response rate.
- The expected therapeutic dose of NXC-201 (800 million CAR+T cells) has already been established as the recommended Phase 2 dose (RP2D) for both multiple myeloma and AL amyloidosis.
Additional information on NXC-201 multiple myeloma clinical data as of October 23, 2022 is available here.
About NEXICART-1
NEXICART-1 (NCT04720313) is an ongoing Phase 1b/2, open-label study evaluating the safety and efficacy of NXC-201 (formerly HBI0101) in adults with relapsed or refractory multiple myeloma and AL amyloidosis. The Phase 1b portion of the study has already established an expected recommended Phase 2 dose (RP2D) of 800 million CAR+T cells.
The expected primary endpoint for a pivotal study of NXC-201 will be overall response rate in multiple myeloma, and overall response rate in AL amyloidosis.
To date, 58 patients have been treated with NXC-201, 50 in multiple myeloma, and 8 in AL amyloidosis.
About AL Amyloidosis
AL amyloidosis is a rare systemic disorder caused by an abnormality of plasma cells in the bone marrow. Misfolded amyloid proteins produced by plasma cells cause buildup in and around tissues, nerves and organs, gradually affecting their function. This can cause progressive and widespread organ damage, and high mortality rates.
AL amyloidosis affects roughly 30,000 – 40,000 patients in total throughout the U.S. and Europe, and it is estimated that there are approximately 3,000 – 4,000 new cases of AL amyloidosis annually in the U.S. The annual global incidence of AL Amyloidosis is ~15,000 patients. The Amyloidosis market was
About Multiple Myeloma
Multiple myeloma (“MM”) is an incurable blood cancer of plasma cells that starts in the bone marrow and is characterized by an excessive proliferation of these cells. Despite initial remission, unfortunately, most patients are likely to relapse. There are 34,470 patients in the United States diagnosed with MM each year. Prognosis for patients who do not respond to or relapse after treatment with standard therapies, including protease inhibitors and immunomodulatory agents remains poor. The
