Nov 2025Series BAtlas Venture (lead); Forbion Capital Partners (lead); Schroders Capital (lead)$141MAAVantgarde Bio is a clinical-stage biotechnology company spun out of the Telethon Institute for Genetics and Medicine (TIGEM) in Naples, Italy, developing gene therapies for inherited retinal diseases (IRDs) such as Stargardt disease and Usher 1B syndrome. The company closed a $141 million (€122 million) Series B financing round on November 3, 2025, co-led by Schroders Capital, Atlas Venture, and Forbion Capital Partners, with participation from new investors including Amgen Ventures, Athos Capital, CDP Venture Capital, Columbia IMC, Neva SGR, Sixty Degree Capital, XGen Venture, and Willett Advisors, plus existing backers Longwood Fund and Sofinnova Partners (or Sofinnova Telethon Fund). This followed a €61 million ($71 million) Series A in 2023. Proceeds will fund completion of proof-of-concept for the AAVB-039 CELESTE Phase 1/2 trial in Stargardt disease patients (caused by ABCA4 gene mutations), delivering full-length ABCA4 protein via an improved AAV platform, and the AAVB-081 LUCE Phase 1/2 trial for retinitis pigmentosa in Usher 1B syndrome (MYO7A mutations), alongside the STELLA natural history study involving over 100 Stargardt patients. AAVB-039 recently received FDA Orphan Drug Designation and UK MHRA Clinical Trial Authorisation. The platform overcomes AAV technology barriers for better delivery in eye diseases with limited treatments. Leadership includes CEO Dr. Natalia Misciattelli, CSO and founder Prof. Alberto Auricchio (TIGEM scientific director), and board member Dr. Peter Kaiser (Cleveland Clinic). Investors highlighted the team's science and potential for best-in-class therapies addressing root genetic causes of progressive vision loss in underserved patients. AAVantgarde recently moved into incubator space at Victoria House.
