HAYA Therapeutics raises USD 65m in Series-A-Funding

HAYA Therapeutics AG has successfully closed its Series-A-financing round of USD 65m – an important step toward its vision of reprogramming disease-causing cellular states.

HAYA, a biotechnology company based in Lausanne, develops RNA-based therapies for the targeted reprogramming of diseased cellular programs. To do this, HAYA uses lncRNAs from the “dark genome,” a previously understudied area of the genome. With its proprietary platform combining genome research and AI, HAYA is developing innovative treatments for chronic diseases. The drug candidate HTX-001 is the first IncRNA therapy of its kind for heart failure. Further programs target chronic diseases such as pulmonary fibrosis, obesity, and metabolic disorders. Supported by high-profile investors and an experienced team, HAYA is advancing the potential of the “dark genome” for new therapies.

VISCHER advises HAYA Therapeutics AG on all Swiss legal issues related to the financing. The VISCHER team is led by Pauline Pfirter (Senior Associate, Corporate/M&A) and Christian Wyss (Partner, Corporate/M&A) and includes Rahel Widmer (Associate, Corporate/M&A), Marc Prinz (Partner, Employment), Lukas Züst (Partner, Corporate/M&A), Dr. Thomas Gelzer (Senior Counsel), Kelly Chevrolet (Junior Associate), and Elena Weller (Junior Associate).
