February 25, 2021

SOUTH SAN FRANCISCO, Calif., Feb. 25, 2021 (GLOBE NEWSWIRE) -- Assembly Biosciences, Inc. (Nasdaq: ASMB), a clinical-stage biotechnology company developing innovative therapeutics targeting hepatitis B virus (HBV), today reported financial results and recent highlights for the fourth quarter and year ended December 31, 2020.

“Our strategy for 2021 and beyond is to focus entirely on developing finite and curative therapies that have the potential to free patients with chronic HBV infection from a lifetime of therapy. We are well positioned to do this by advancing our more potent next generation core inhibitors, which include three novel compounds in the clinic and a fourth candidate in pre-IND development, exploring multiple triple combination studies of vebicorvir with complementary mechanisms of action, and expanding our internal research efforts to discover and develop candidates against novel targets,” said John McHutchison, AO, MD, Chief Executive Officer and President of Assembly Bio.
