AnnJi Showcases Clinical Breakthrough of AJ201 at WMS 2025

Dr. Andrew Pai presented the latest preclinical research of Rosolutamide (JM17), the active ingredient of AJ201. JM17 demonstrated multi-pathway benefits in SBMA mouse model, including enhanced mitochondrial function, reduced inflammation and fibrosis, as well as improved structural organization of muscle fibers. Upstream regulator analysis further confirmed the inhibition of pro-inflammatory mediators (TNF-α, IL-6, TGF-β) alongside activation of protective signaling pathways. These findings underscore JM17's potential as a multi-functional therapeutic candidate, providing new mechanistic insights for SBMA treatment.

"We are very proud of the Late Breaking Abstract, as well as the preclinical research paper presented at the 2025 WMS, which highlighted the significant advancement we have made in the development of AJ201 toward the world's first effective therapy for Kennedy's disease." said Dr. Wendy Huang, CEO and Chairperson of the Board of AnnJi.

AJ201 has been granted Orphan Drug Designation by both the U.S. FDA and EMA. AnnJi has also built a robust global patent portfolio, securing strong market exclusivity for AJ201. Looking ahead, AnnJi continues advancing AJ201 into Phase 2/3 clinical development and global licensing partnerships, aiming to deliver new hope for patients worldwide and establish AJ201 as a landmark success for Taiwan's new drug industry on the international stage.

About Kennedy's Disease (SBMA)

Kennedy's disease, also known as Spinal and Bulbar Muscular Atrophy (SBMA), is a rare and serious inherited neuromuscular degenerative disorder. It is characterized by the progressive degeneration of lower motor neurons in the spinal cord, brainstem, and skeletal muscles. The disease primarily affects males between the ages of 30 and 40, with an estimated prevalence of 1 in 40,000. As the disease progresses—typically by age 50—patients often develop difficulties with chewing and swallowing, and ultimately, recurrent aspiration pneumonia becomes a common cause of death. Currently, there are no approved treatments for SBMA.
