AnnJi Pharmaceutical Shines with Promising Results for AJ201 in SBMA Treatment Trials
AnnJi Pharmaceutical Co., Ltd., based in Taiwan, has achieved noteworthy advancements in the treatment of Spinal and Bulbar Muscular Atrophy (SBMA) through its investigational drug, AJ201. This clinical-stage biotech firm primarily concentrates on addressing critical medical needs across dermatology, neurology, and rare diseases. Recently, the company shared promising findings from its Phase 1/2a clinical trial involving AJ201, highlighting the drug's potential effectiveness among adults suffering from SBMA.
This clinical study, which followed a randomized, double-blind, placebo-controlled design, was conducted across six clinical sites in the United States. Although the trial was not primarily aimed at evaluating efficacy, exploratory endpoints showed favorable treatment-related improvements that warrant further exploration and development.
The safety profile of AJ201, consistent with earlier studies involving healthy volunteers, indicated that patients generally tolerated the treatment well. Notably, there was no significant drug accumulation in the system, thus reassuring potentials for patient safety.
The results were striking, as participants receiving AJ201 exhibited significant enhancements in both muscle strength and physical function after a 12-week oral treatment period. Participants showed a statistically significant increase of 17.6 meters in the 6-Minute Walk Test (6MWT) and an average rise of 0.8 points on the SBMA Functional Rating Scale (SBMAFRS). In contrast, the placebo group experienced minor declines in similar assessments. Furthermore, AJ201 demonstrated a reduction in serum levels of creatine kinase and myoglobin, indicating a beneficial therapeutic effect. Among those assessed, an impressive proportion of the AJ201 group (11 out of 15 in the 6MWT, 6 out of 7 in SBMAFRS, 14 out of 14 in creatine kinase, and 11 out of 12 in myoglobin) showed significant positive responses. Adding further weight to these observations, patients treated with AJ201 reported improvement in their physical health quality of life, as per the SF36v2 quality-of-life questionnaire, while the placebo recipients showed a decline.
Crucial assessments targeting mutant androgen receptors (mAR)—a biomarker associated with SBMA—were performed through muscle biopsies. Findings revealed a reduction of over 50% in nuclear mAR levels for 53% of the patients on AJ201 compared to just 17% of those on the placebo. This significant correlation suggests that AJ201 may effectively target SBMA on a molecular level. Additionally, RNA sequencing from AJ201-treated patients revealed activation of the Nrf2 pathway and modulation in several disease-related signaling pathways, changes that were not seen in the placebo group, thereby reinforcing the drug’s potential mechanism of action.
With consistent improvements noted in functional, biochemical, and molecular parameters, the study builds a solid foundation for continued exploration of AJ201 in SBMA. Dr. Christopher Grunseich, the Principal Investigator of the study and a notable Lasker Clinical Research Scholar, expressed optimism, stating, "The study results are highly encouraging. AJ201 has shown evidence of clinical benefit, demonstrated through improvements in functional assessments, positive shifts in serum biomarkers, and RNA sequencing data supporting activation of the Nrf2 pathway. These findings reinforce the therapeutic potential of AJ201."
Wendy Huang, Ph.D., CEO and Chairperson at AnnJi, noted the implications of these positive clinical outcomes. "SBMA is a slowly progressive neuromuscular disorder, and I am greatly encouraged by the positive clinical outcomes observed after a relatively short course of AJ201 treatment. We are committed to advancing the program into Phase 3 clinical trials, with hopes of providing effective solutions for SBMA sufferers, a demographic currently without FDA-approved therapeutic options.”
SBMA, often referred to as Kennedy’s disease, is an infrequent X-linked hereditary neuromuscular condition occurring due to CAG repeat expansions in the androgen receptor (AR) gene, leading to muscle and neuron degradation. It is estimated to affect around 1 in every 40,000 males worldwide and remains without an FDA-sanctioned treatment.
AJ201, also known as JM17, is emerging as a promising investigational drug, looking to mitigate mutant AR toxicity and enhance motor capabilities in SBMA preclinical models. It operates at the molecular level by promoting the breakdown of harmful mAR proteins and inducing protective cellular mechanisms, including antioxidant enzymes and Heat shock proteins.
Founded in 2014, AnnJi Pharmaceutical has consistently dedicated itself to developing cutting-edge therapies aimed at serious and neglected medical conditions, particularly through strong global collaborations. For more details, you can visit their official website at www.ajpharm.com.
