AnnJi Pharmaceutical Co., Ltd. has launched a first-in-patient Phase 1/2a study of AJ201, a curcumin-based compound, to evaluate its safety, tolerability, and related biochemical and pharmacological activities in Kennedy’s Disease patients. The study will be conducted at six sites in the United States in 2023. The distribution sites are listed below. AJ201 is designed to activate the Nrf1 and Nrf2 cellular pathways to promote degradation of the mutant androgen receptor (AR) protein that is responsible for Kennedy’s Disease. AJ201 has been granted orphan drug status by the FDA and EMA for the treatment of Kennedy’s Disease. AnnJi has entered a licensing arrangement with Avenue Therapeutics for the development and eventual commercialization of AJ201. For more information, visit Avenue Therapeutics.
