Atsena Therapeutics is a clinical-stage gene therapy company developing novel treatments for inherited forms of blindness. The company has two clinical-stage programs, ATSN-201 for X-linked retinoschisis (XLRS) and ATSN-101 for GUCY2D-associated Leber congenital amaurosis (LCA1). ATSN-201, which leverages the company’s novel spreading capsid AAV.SPR, is being evaluated in XLRS patients in a Phase I/II clinical trial known as the LIGHTHOUSE study. The company’s additional proprietary asset is ATSN-301, a dual AAV vector-based gene therapy to prevent blindness from MYO7A-associated Usher syndrome (USH1B). Interim safety and efficacy data from the company’s ongoing Phase I/II clinical trial in patients with LCA1 have demonstrated ATSN-101 is well tolerated and clinically meaningful improvements in vision were observed 12 months post-treatment. Founded by ocular gene therapy pioneers Dr. Shannon Boye and Sanford Boye of the University of Florida, Atsena is based in North Carolina’s Research Triangle, an environment rich in gene therapy expertise.
