Experts and advocates to provide important strategic input and clinical expertise as ACELYRIN completes its Phase 2 trial of lonigutamab in TED and prepares to initiate Phase 3 program in first quarter of 2025

LOS ANGELES, Oct. 16, 2024 (GLOBE NEWSWIRE) -- ACELYRIN, INC. (Nasdaq: SLRN), a late-stage clinical biopharma company focused on accelerating the development and delivery of transformative medicines in immunology, today announced the formation of a scientific and patient advisory board comprised of leading experts and advocates in thyroid eye disease (TED). This group of advisors will provide important strategic input, clinical expertise and patient perspectives as ACELYRIN prepares to advance lonigutamab, a subcutaneously delivered IgG1 monoclonal antibody targeting the anti-insulin-like growth factor 1 (IGF-1) receptor, into Phase 3 clinical development for TED in the first quarter of 2025.

“Convening this esteemed group of clinical thought leaders and patient advocates is an important step forward for us as we prepare to advance lonigutamab into the pivotal Phase 3 program for TED,” said Shephard (Shep) Mpofu, M.D., Chief Medical Officer of ACELYRIN. “Each member brings distinct expertise spanning multiple facets of TED including disease pathology, clinical trial leadership and patient experience. We believe their collective insights will position us extremely well to execute on our goal of delivering the potentially best-in-class subcutaneous anti-IGF-1R treatment for TED patients.”

About Thyroid Eye Disease
Thyroid Eye Disease (TED) is a vision-threatening autoimmune disease in which there is both inflammation and expansion of the tissues behind the eye, resulting in eye bulging, known as proptosis, and the subsequent inability to close the eyelids. Double vision, or diplopia, can occur, as well as the potential for compression of the optic nerve, which can lead to blindness. Thus, TED is a progressive, chronic inflammatory disease. More than 100,000 people in the United States are estimated to suffer from TED.

About Lonigutamab
Lonigutamab is a humanized IgG1 monoclonal antibody targeting the anti-insulin-like growth factor 1 (IGF-1) receptor and is delivered subcutaneously. Relative to standard of care, lonigutamab binds to a distinct epitope, which results in internalization of the receptor within minutes, and in preclinical binding and functional laboratory assays, it has been shown to be 75-fold more potent. The characteristics of lonigutamab that enable subcutaneous delivery also enable the potential for longer-term, convenient dosing, which can potentially improve depth and durability of clinical response.
