- Dosing initiated in healthy participants in Phase 1a/b trial for ABI-5366 targeting recurrent genital herpes, with interim Phase 1a first-in-human data expected in Q3 2024 and interim Phase 1b data in participants with recurrent genital herpes expected in first half of 2025
- Dosing initiated in Phase 1b trial for ABI-4334 in participants with chronic HBV infection, with interim Phase 1b data expected by end of year
- Two additional pipeline candidates, ABI-1179 and ABI-6250, anticipated to enter clinic by end of year
SOUTH SAN FRANCISCO, Calif., Aug. 08, 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 second quarter ended June 30, 2024.
“Entering the second half of the year, I’m incredibly proud of our team’s accomplishments on our path to delivering novel therapeutics for individuals living with serious viral diseases,” said Jason Okazaki, chief executive officer and president of Assembly Bio. “We are rapidly progressing toward key inflection points for our clinical development programs and remain on track with the data sets we plan to deliver in 2024. Specifically, in the third quarter, we look forward to sharing interim Phase 1a data for ABI-5366 in healthy participants. The pharmacokinetic data in this study will enable us to assess ABI-5366’s ability to reach the target concentrations we have established for antiviral efficacy and to support our once-weekly oral dosing profile, while also informing dose selection in the Phase 1b part of the study in participants with recurrent genital herpes.”
Second Quarter 2024 and Recent Highlights
- First participants were dosed in two clinical trials:
- The Phase 1a portion of a Phase 1a/b clinical study of ABI-5366, a long-acting herpes simplex virus (HSV) helicase-primase inhibitor candidate; the Phase 1a portion in healthy participants and the Phase 1b portion to be conducted in participants with recurrent genital herpes
- A Phase 1b study of ABI-4334, a next-generation, highly potent capsid assembly modulator candidate, in participants with chronic hepatitis B virus (HBV) infection
- Scientific conference presentations highlighted:
- Preclinical data for ABI-5366 (poster presentation) and ABI-1179 (poster and oral presentation) featured at the International Herpesvirus Workshop held July 13-17, 2024. ABI-1179 is the long-acting HSV helicase-primase inhibitor candidate contributed by Gilead Sciences, Inc. (Gilead) under the collaboration between Assembly Bio and Gilead
- Preclinical data for ABI-6250, an oral, small molecule HBV/hepatitis delta virus (HDV) entry inhibitor candidate, featured in a poster presentation at the European Association for the Study of the Liver (EASL) Congress™ 2024 held June 5-8, 2024
- Preclinical data for ABI-6250 featured in an oral presentation at the Science of HBV Cure Meeting 2024 held July 26-27, 2024
- Strengthened balance sheet with equity investments that resulted in aggregate gross proceeds to Assembly Bio of approximately $12.6 million, supporting advancement of antiviral portfolio and extending cash runway into Q1 2026
Upcoming Anticipated Milestones
- ABI-5366 Phase 1a interim clinical data in healthy participants expected in Q3 2024 and interim Phase 1b data in participants with recurrent genital herpes expected in the first half of 2025
- ABI-4334 Phase 1b interim clinical data expected by the end of 2024
- Two additional candidates, ABI-1179 and ABI-6250, are anticipated to enter the clinic by the end of 2024
Upcoming Conferences
- Abstract highlighting preclinical data for ABI-6250 accepted for poster presentation at the International HBV Meeting taking place September 11-15, 2024, in Chicago
Second Quarter 2024 Financial Results
- Cash, cash equivalents and marketable securities were $109.2 million as of June 30, 2024, compared to $113.0 million as of March 31, 2024. Assembly Bio’s cash position is projected to fund operations into Q1 2026.
- Revenue from collaborative research was $8.5 million for the three months ended June 30, 2024. There was no revenue recognized for the same period in 2023. Revenue for the three months ended June 30, 2024, consists of amounts recognized under the collaboration with Gilead.
- Research and development expenses were $16.3 million for the three months ended June 30, 2024, compared to $12.5 million for the same period in 2023. The increase is attributable to having more candidates in development in 2024.
- General and administrative expenses were $4.5 million for the three months ended June 30, 2024, compared to $5.0 million for the same period in 2023. The decrease is primarily due to a decrease in non-cash stock-based compensation expense.
- Net loss attributable to common stockholders was $11.2 million, or $1.98 per basic and diluted share, for the three months ended June 30, 2024, compared to $16.9 million, or $3.88 per basic and diluted share, for the same period in 2023.
