VLTR-559 / Valitor - LARVOL DELTA

Multivalent conjugation of anti-VEGF antibody to hyaluronic acid is well-tolerated and retains potency in ocular tissues for extended durability. (ARVO 2026) - "Valitor is developing an improved biotechnology product with the aim of reducing the frequency of anti-VEGF drug administration to just twice yearly, thereby improving the long-term efficacy while also reducing the clinical costs required to treat these diseases. This abstract outlines the key preclinical results that have enabled predictions that our long-acting anti-VEGF product candidate (VLTR-559) could treat wet-AMD in a reliable 6-month dosing frequency for most patients."

Valitor Presents Preclinical Data Demonstrating VLTR-559 Achieves Superior Durability and Sustained Anti-VEGF Activity with a Favorable Safety Profile as a Treatment for Wet AMD (GlobeNewswire) - "Preclinical results support 6-month dosing, demonstrating VLTR-559’s substantially longer ocular half-life, with high drug concentrations retained in the retina compared to current anti-VEGF standard of care....VLTR-559 was well tolerated at target clinical dose with a safety profile similar to approved short-acting anti-VEGF therapies for wet AMD. Data featured in an oral presentation at the at the Eyecelerator Conference held in conjunction with the AAO 2025 Annual Meeting."
