- Positive Phase 1a interim data released for ABI-5366, a long-acting HSV helicase-primase inhibitor candidate for recurrent genital herpes, supporting potential for once-weekly and once-monthly oral dosing
- First participants dosed in Phase 1b trial evaluating ABI-5366 in individuals with recurrent genital herpes with interim data expected in first half of 2025
- Phase 1b trial for ABI-4334, a next-generation highly potent capsid assembly modulator candidate, ongoing in participants with chronic HBV with interim data expected by end of year
- ABI-1179 and ABI-6250 candidates on track to enter clinic by end of year
SOUTH SAN FRANCISCO, Calif., Nov. 07, 2024 (GLOBE NEWSWIRE) -- Assembly Biosciences, Inc. (Nasdaq: ASMB), a biotechnology company developing innovative therapeutics targeting serious viral diseases, today reported financial results and recent updates for the third quarter ended September 30, 2024.
“I’m thrilled with the continued execution against our ambitious goal of advancing four candidates targeting serious viral diseases in the clinic and releasing two interim data sets by year end,” said Jason Okazaki, chief executive officer and president of Assembly Bio. “We recently reported positive interim Phase 1a data for ABI-5366 that exceeded our expectations and supported the initiation of dosing in participants with recurrent genital herpes for the Phase 1b portion of the study. We look forward to adding two candidates to our clinical pipeline in the fourth quarter with the initiation of Phase 1 studies for ABI-1179 and ABI-6250.”
Third Quarter 2024 and Recent Highlights
- Positive Phase 1a interim data were released for ABI-5366 and dosing was initiated in the Phase 1b portion of the ongoing Phase 1a/b trial
- In Phase 1a interim data, ABI-5366 was well-tolerated with a favorable safety profile observed with exposures of up to 70 days and a half-life of approximately 20 days when dosed orally
- The Phase 1b study portion in participants with recurrent genital herpes is expected to explore both once-weekly and once-monthly oral dosing; interim data are expected in the first half of 2025
- Regulatory clearance was received for a Phase 1a/b study for ABI-1179, a long-acting herpes simplex virus (HSV) helicase-primase inhibitor contributed by Gilead Sciences, Inc. (Gilead) under the collaboration between Assembly Bio and Gilead
- Anuj Gaggar, MD, PhD, chief medical officer, and William Delaney, PhD, chief scientific officer, presented during the H.C. Wainwright 5th Annual Viral Hepatitis Virtual Conference held October 8, 2024
- Preclinical data for ABI-6250, an oral, small molecule hepatitis B virus (HBV)/hepatitis delta virus (HDV) entry inhibitor candidate, were highlighted in a poster presentation at the International HBV Meeting held September 11-15, 2024
Upcoming Anticipated Milestones
- ABI-5366 Phase 1b interim clinical data in participants with recurrent genital herpes expected in the first half of 2025
- ABI-4334 Phase 1b interim clinical data in participants with chronic HBV expected by the end of 2024
- ABI-1179 and ABI-6250 both on track to enter the clinic by the end of 2024
Third Quarter 2024 Financial Results
- Cash, cash equivalents and marketable securities were $95.0 million as of September 30, 2024, compared to $109.2 million as of June 30, 2024. Assembly Bio’s cash position is projected to fund operations into Q1 2026.
