$115 Million Financing Secured

The Phase 2 clinical trial for the herpes simplex virus helicase primase inhibitor GS-1179 is set to commence by year-end 2026, as outlined in the company’s collaboration with Gilead Sciences, Inc. This advancing pipeline presents significant growth opportunities, indicating a strong strategy focused on diseases with unmet medical needs.

Strategic Collaborations

Collaboration with Gilead continues to strengthen Assembly Biosciences' position in the market.
