AELIX Therapeutics is a Barcelona-based clinical-stage biotech spun off from HIVACAT that develops the HTI immunogen, a therapeutic HIV vaccine designed to help achieve functional HIV cure/eradication. In November 2024 Gilead Sciences acquired AELIX's HTI HIV vaccine investigational assets; the company now appears to operate with a very small team (~2 employees).
