U.S. Food and Drug Administration Approves Orphan Drug Designation for Immix Biopharma NXC-201 as a Treatment for Multiple Myeloma

FDA Orphan Drug Designation (“ODD”) qualifies NXC-201 for:

• 7 years of U.S. market exclusivity after approval
• Tax credits for qualified clinical testing
• Waiver of the Prescription Drug User Fee (currently at almost $3 million for a new drug)
• 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

LOS ANGELES, Aug. 23, 2023 (GLOBE NEWSWIRE) — Immix Biopharma, Inc. (Nasdaq: IMMX) (“ImmixBio” or the “Company”), a clinical-stage biopharmaceutical company pioneering personalized therapies for oncology and immunology, announced today that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation (ODD) designation for NXC-201 for the treatment of a life-threatening form of blood cancer, multiple myeloma. NXC-201, a next generation CAR-T cell therapy, is currently being evaluated in a Phase 1b/2a clinical trial NEXICART-1 (NCT04720313).

The FDA’s Office of Orphan Products Development grants orphan designation status to drugs and biologics that are intended for the safe and effective treatment, diagnosis or prevention of rare diseases, or conditions that affect fewer than 200,000 people in the U.S. Orphan Drug Designation provides certain benefits, including financial incentives, to support clinical development and the potential for up to 7 years of market exclusivity in the U.S. upon regulatory approval.

“We are pleased to receive FDA’s orphan drug designation in multiple myeloma for NXC-201, the only clinical-stage BCMA-targeted CAR-T cell therapy with no neurotoxicity observed in over 50 patients dosed to date,” said Ilya Rachman, MD, PhD, Immix Biopharma Chief Executive Officer.  Dr. Rachman continued, “We are thrilled to potentially expand therapeutic options for multiple myeloma patients, while eliminating the most feared adverse effect of this therapeutic class, neurotoxicity.” 

Gabriel Morris, Immix Biopharma Chief Financial Officer, added, “Orphan drug designation for NXC-201 represents a substantial value creating step along our path to unlocking planned wide adoption of CAR-T technology by transitioning it to an outpatient domain.”

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.
