With this investment, we are well-positioned to advance additional programs into the clinic and continue to move our lead program forward."

    Dr. Albert Huang, Managing Director at Yunfeng Capital noted, "The fast-growing aging population leads to a high demand for the therapy of age-related degenerative diseases. Over the past 20 years, Dr. Xiaodong Wang has devoted himself to programmed cell death research, unearthing a novel mechanism of aging and degenerative disease, which has laid the foundation of scientific success for Sironax. We look forward to a lasting partnership with Dr. Wang, Dr. Ren and the entire Sironax team, and strongly believe the Company has the potential to develop effective solutions for age-related degenerative diseases."
