Immix Biopharma Subsidiary Nexcella Announces Commencement of NXC-201 Engineering Batches at its U.S. CAR-T Manufacturing Site

  • U.S. engineering batches support planned expansion of its ongoing NEXICART-1 (NCT04720313) NXC-201 CAR-T clinical trial to the United States
  • Engineering batches are the first step in transferring the Company’s existing CAR-T GMP manufacturing process to the United States
  • Commencement of U.S. engineering batches follows selection of U.S. GMP manufacturer in February 2023

LOS ANGELES, May 26, 2023 (GLOBE NEWSWIRE) -- Nexcella, Inc., a subsidiary of Immix Biopharma, Inc. (“Nexcella”, “Company”, “We” or “Us”), today announced the commencement of CAR-T NXC-201 Engineering Batches at its U.S. Manufacturing Site. These U.S. engineering batches will support the planned U.S. expansion of the Company’s ongoing Phase 1b/2a NEXICART-1 (NCT04720313) study of its novel BCMA-targeted chimeric antigen receptor T (car-T) cell therapy NXC-201.  This manufacturing milestone represents a crucial next step in transferring the Company’s existing CAR-T GMP manufacturing process to the United States following the selection of a U.S. GMP manufacturer in February 2023.

“We are working tirelessly to bring NXC-201 to U.S. patients,” said Ilya Rachman, M.D. PhD Chief Executive Officer of Immix Biopharma. “NXC-201 is the first CAR-T being developed in AL Amyloidosis, and in Multiple Myeloma, patients face significant obstacles when seeking BCMA-targeted CAR-T treatments like NXC-201. We look forward to continuing to advance NXC-201 as we work to improve treatment outcomes for patients in the U.S. suffering from AL amyloidosis and multiple myeloma.”

“Today, 95% of U.S. medical centers are unable to offer CAR-T cell therapy,” said Gabriel Morris, Chief Financial Officer of Immix Biopharma. “NXC-201 has already been trialed in over 50 patients, demonstrating a 1-2 day median short side-effect duration, which offers potential to become the first out-patient CAR-T, potentially reducing hospitalization costs up to 80% and enabling dosing in 95% of U.S. medical centers today unable to offer CAR-T cell therapy.”

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 across 58 patients.

About NEXICART-1

NEXICART-1 (NCT04720313) is an ongoing Phase 1b/2a, 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 primary objective of the Phase 1b portion of the study was to characterize the safety and confirm the recommended Phase 2 dose (RP2D) and Phase 2 dose of NXC-201. The Phase 2 portion of the study will evaluate the efficacy and safety of NXC-201 with endpoints of overall survival, progression-free survival and response rates according to International Myeloma Working Group (IMWG) Uniform Response Criteria.

The Phase 1b portion of the ongoing Phase 1b/2a clinical trial has been successful in determining the recommended Phase 2 dose (RP2D) of 800 million CAR+T cells. Over the coming months, Nexcella plans to submit an IND application to the FDA for a Phase 1b/2 of NXC-201 in relapsed/refractory multiple myeloma and AL amyloidosis in order to expand the ongoing clinical trial to the U.S. The expected primary endpoint for the Phase 2 portion of the ongoing Phase 1b/2a clinical trial of NXC-201 in relapsed/refractory multiple myeloma is overall response rate and duration of response. Nexcella plans to submit data to the FDA in multiple myeloma once 100 patients are treated with NXC-201. The expected primary endpoint for NXC-201 in relapsed/refractory AL Amyloidosis is overall response rate. Nexcella plans to submit data to the FDA in AL amyloidosis once 30-40 patients are treated with NXC-201.

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 $3.6 billion in 2017, expected to reach $6 billion in 2025, according to Grand View Research.

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 35,730 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 $13.9 billion Multiple Myeloma market in 2017 is expected to reach $28.7 billion in 2027 according to Wilcock, et al. Nature Reviews
