New Sites Expand Opportunities for Patient Access and Enrollment
Clinical Trial Sites Added Include Cleveland Clinic, UC Davis, and Sutter Health
Lead site Memorial Sloan Kettering Cancer Center (MSKCC)
Data from ex-U.S. clinical trial reported at ASGCT 2024 showed a 92% overall response rate
LOS ANGELES, CA, Aug. 28, 2024 (GLOBE NEWSWIRE) -- Immix Biopharma, Inc. (“ImmixBio”, “Company”, “We” or “Us”, “IMMX”) (Nasdaq: IMMX), a clinical-stage biopharmaceutical company developing cell therapies for AL Amyloidosis and immune-mediated diseases, today announced the addition of three additional clinical trial sites for its U.S. relapsed/refractory AL Amyloidosis clinical trial NEXICART-2. The newly added centers include some of the leading programs in the world in AL Amyloidosis. New sites expand opportunities for patient access to CAR-T NXC-201 across the U.S. MSKCC remains the lead clinical site.
The NEXICART-2 study is intended to evaluate the safety and efficacy of CAR-T NXC-201 in relapsed/refractory AL Amyloidosis patients with adequate cardiac function who have not been exposed to prior BCMA-targeted therapy. The study builds on positive data from the initial ex-U.S. study, NEXICART-1, presented at the 27th Annual Meeting of The American Society of Gene and Cell Therapy (ASGCT 2024) which showed a 92% overall response rate in relapsed/refractory AL Amyloidosis patients (12/13). The best responder experienced a 28.0 month duration of response (as reported May 10, 2024).
“In our mission to advance treatment options for relapsed/refractory AL Amyloidosis patients, we are proud to expand our NEXICART-2 clinical trial footprint to a national scale with the addition of these world-class sites and exceptional principal investigators,” said Ilya Rachman, M.D., Ph.D., Chief Executive Officer of Immix Biopharma. Gabriel Morris, Chief Financial Officer of Immix Biopharma, added, “Working with our outstanding team and partners, these additional sites support upcoming interim and final read-outs of NEXICART-2.”
About NEXICART-2 NEXICART-2 (NCT06097832) is an open-label, single-arm, multi-site U.S. Phase 1b/2 dose expansion clinical trial of CAR-T NXC-201 in relapsed/refractory AL Amyloidosis. NEXICART-2 is expected to enroll 40 patients with adequate cardiac function who have not been exposed to prior BCMA-targeted therapy. The study is designed with a standard 6 patient safety-run in to evaluate two doses (three patients each at 150 million CAR+T cells and 450 million CAR+T cells), with the potential for further escalation to 800 million CAR+T cells (all 3 dose levels were evaluated in the NEXICART-1 study and have produced complete responses in relapsed/refractory AL Amyloidosis patients). The study aims to evaluate the safety and efficacy of NXC-201 in this patient population. Primary endpoints are complete response rate and overall response rate, according to consensus recommendations (Palladini et al. 2012).
About NEXICART-1 NEXICART-1 (NCT04720313) is an open-label, ex-U.S. Phase 1b/2 clinical trial of NXC-201 (formerly HBI0101) in patients with relapsed/refractory multiple myeloma and relapsed/refractory AL amyloidosis (including AL Amyloidosis patients with impaired cardiac function and including AL Amyloidosis patients exposed to prior BCMA-targeted therapy). The primary objective of the study is to characterize the safety and efficacy, as well as confirm the recommended Phase 2 dose (RP2D) of NXC-201 (which has already been confirmed). NEXICART-1 clinical results, most recently from ASGCT 2024, are available at https://immixbio.com/pipeline/#publications.
About NXC-201 NXC-201 is a sterically-optimized BCMA-targeted chimeric antigen receptor T (CAR-T) cell therapy. Initial data from Phase 1b/2 ex-U.S. study NEXICART-1 has demonstrated no neurotoxicity of any kind in AL Amyloidosis.
NXC-201 is being studied in a comprehensive clinical development program for the treatment of patients with relapsed/refractory AL amyloidosis, with the potential to expand into immune-mediated diseases. The NXC-201 NEXICART-2 (NCT06097832) U.S. clinical trial builds on a robust clinical dataset. NXC-201 has been awarded Orphan Drug Designation (ODD) in AL Amyloidosis by the US FDA and in the EU by the EMA.
About AL Amyloidosis AL amyloidosis is caused by abnormal plasma cells in the bone marrow, which produce misfolded amyloid proteins that build-up in the heart, kidney, liver, and other organs. This build-up causes progressive and widespread damage to multiple organs, including heart failure, and leads to high mortality rates.
The U.S. observed prevalence of relapsed/refractory AL Amyloidosis is estimated to be growing at 12% per year according to Staron, et al Blood Cancer Journal, to approximately 33,277 patients in 2024.
The Amyloidosis market was $3.6 billion in 2017, and is expected to reach $6 billion in 2025, according to Grand View Research.
About Immix Biopharma, Inc. Immix Biopharma, Inc. (ImmixBio) (Nasdaq: IMMX) is a clinical-stage biopharmaceutical company developing cell therapies for AL Amyloidosis and immune-mediated diseases. Our lead candidate is sterically-optimized BCMA-targeted chimeric antigen receptor T (CAR-T) cell therapy NXC-201.
