SAN FRANCISCO, Calif., Sept. 06, 2022 (GLOBE NEWSWIRE) — Attralus, Inc., a clinical stage biopharmaceutical company developing transformative medicines to improve the lives of patients with systemic amyloidosis, today announced exciting new preclinical data from the University of Tennessee Graduate School of Medicine from its study on novel human chimeric antigen receptor-macrophages (CAR-M) as a potential therapeutic for amyloid clearance. The data was included in an oral presentation at the 18th International Symposium on Amyloidosis (ISA) taking place September 4-8, 2022, in Heidelberg, Germany.
Data presented at ISA demonstrates a novel use of the Company’s pan-amyloid removal (PAR) technology in which human CAR macrophages incorporate the pan-amyloid reactive p5 peptide as the amyloid-binding moiety. The p5 peptide is related to the basic peptide used in the Company’s diagnostic agent, AT-01 (iodine (I-124) evuzamitide), as well as its therapeutic candidates AT-02 and AT-04. Expression of the CAR in human THP-1 cells enhanced phagocytosis of human amyloid extracts and has the potential to serve as a standalone therapy or as an adjunct to other PAR therapeutics to enhance the removal of amyloid.
“The use of amyloid-reactive CAR-M is an exciting novel approach to facilitate the macrophage-mediated removal of systemic amyloidosis,” said Gregory Bell, MD, Chief Medical Officer at Attralus. “We are excited to explore more opportunities to potentially transform the treatment of these diseases and improve the lives of patients.”
Results Summary
“We have seen the innovations in CAR-T and CAR-M approaches to the treatment of cancers. We were eager to see if the same concept could be used to promote phagocytosis of amyloid,” said Jonathan Wall, Ph.D., Distinguished Professor, University of Tennessee Graduate School of Medicine. “We are enthusiastic about our ability to leverage the PAR technology in new and innovative ways, in this case cell therapy.”

About CAR-M PAR Therapeutic
CAR-M is a fusion of Attralus’s pan-amyloid reactive p5 peptide as the amyloid binding moiety and human chimeric antigen receptor-macrophages. The proprietary peptide binds to all types of amyloid and delivers the CAR-M to the site of disease to stimulate the immune system to remove amyloid. The same PAR-peptide technology is utilized in other Attralus therapies and diagnostics.
About Systemic Amyloidosis
Systemic amyloidosis encompasses a diverse group of rare diseases that occur due to accumulation of toxic amyloid deposits in tissues and organs, a consequence of aberrant protein misfolding events. These diseases are progressive, debilitating and often fatal. Systemic amyloidosis is significantly underdiagnosed due to low awareness, lack of specific symptoms, and no current disease-specific diagnostics. The two most common forms of systemic amyloidosis are immunoglobulin light-chain-associated (AL) amyloidosis and transthyretin-associated amyloidosis (ATTR). There is a significant unmet need for new therapies and diagnostics in systemic amyloidosis.
About Attralus
Attralus is a clinical stage biopharmaceutical company focused on creating transformative medicines to improve the lives of patients with systemic amyloidosis. The company’s proprietary pan-amyloid removal (PAR) therapeutics are designed to directly bind to and remove toxic amyloid in organs and tissues. By targeting the universal disease-causing pathology in systemic amyloidosis diseases, PAR therapeutics have the potential to treat and reverse disease in patients with all types and stages of systemic amyloidosis. Attralus was founded by scientific experts in the field of amyloidosis and the company is headquartered in San Francisco.
