- Herpesvirus candidate ABI-5366 progressing towards IND and planned to enter the clinic in the first half of 2024
- Additional development candidate nomination anticipated in 2023
- Multiple abstracts accepted for presentation at EASL 2023 in June
SOUTH SAN FRANCISCO, Calif., May 04, 2023 (GLOBE NEWSWIRE) -- Assembly Biosciences, Inc. (Nasdaq: ASMB), a biotechnology company developing innovative antiviral therapeutics targeting serious viral diseases, today reported financial results and recent highlights for the first quarter ended March 31, 2023.
“Thanks to the depth and breadth of our team’s virology drug development expertise, we were thrilled to nominate the first development candidate from our expanded virology pipeline, 5366, during the first quarter,” said Jason Okazaki, chief executive officer and president of Assembly Bio. “With 5366 targeting high-recurrence genital herpes expected to enter the clinic in the first half of 2024 and nomination of a second pipeline candidate anticipated later this year, we look forward to advancing these new programs that are designed to address significant unmet medical needs with the potential for shorter paths to reaching key inflection points and clinical proof of concept.”
“With respect to our core inhibitors, we reported promising additional clinical data for 4334 and made the strategic decision to evaluate partnering options for our core inhibitor portfolio,” continued Mr. Okazaki. “We believe partnering the core inhibitors will enable opportunities for further clinical development aimed at achieving a functional cure for HBV, including through combination approaches. It also allows our teams to focus on accelerating 5366 and other compounds in our expanded virology portfolio, which offer us greater potential to have a near-term impact for patients and stockholders.”
First Quarter 2023 and Recent Highlights
- Announced nomination of Assembly Bio’s first herpesvirus development candidate, ABI-5366 (5366), a long-acting helicase inhibitor targeting high-recurrence genital herpes, for advancement to IND-enabling studies
- Reported data updates for two next-generation hepatitis B virus (HBV) core inhibitor candidates including Phase 1b data for ABI-H3733 (3733) in patients with chronic HBV infection and Phase 1a data of ABI-4334 (4334) in healthy subjects
- Announced the company’s intention to prioritize resources on Assembly Bio’s promising portfolio of antiviral programs with shorter paths to clinical proof of concept, including 5366, and evaluate partnering options for its core inhibitor portfolio prior to further clinical development of the mechanism for HBV cure
Anticipated Milestones and Events
- Nominate one additional development candidate from the expanded research portfolio in 2023
- Complete IND/CTA submission for 5366 and enter the clinic in the first half of 2024
- Advance one additional development candidate from a second program into clinical development by year end 2024
- Multiple abstracts accepted for presentation during the European Association for the Study of the Liver (EASL) International Liver CongressTM, June 21-24, 2023, highlighting preclinical data for the company’s oral, small molecule HBV/hepatitis delta virus (HDV) viral entry inhibitor program as well as results from 3733 and 4334 clinical and in vitro studies
- Presentation by Mr. Okazaki and William Delaney, PhD, chief scientific officer of Assembly Bio, during the Jefferies Healthcare Conference, June 7-9, 2023
- Presentation during the Science of HBV Cure meeting held June 2-3, 2023, on next-generation core inhibitors

First Quarter 2023 Financial Results
- Cash, cash equivalents and marketable securities were $73.0 million as of March 31, 2023, compared to $91.6 million as of December 31, 2022. Assembly Bio’s cash position is projected to fund operations into the third quarter of 2024.
- Research and development expenses were $14.5 million for the three months ended March 31, 2023, compared to $17.2 million for the same period in 2022. The decrease is primarily due to the discontinued development of vebicorvir and ABI-H2158 as well as decreases in employee and contractor-related expenses.
- General and administrative expenses were $5.0 million for the three months ended March 31, 2023, compared to $6.0 million for the same period in 2022. The decrease is primarily due to overall cost-saving initiatives.
- Net loss attributable to common stockholders was $19.0 million, or $0.37 per basic and diluted share, for the three months ended March 31, 2023, compared to $23.1 million, or $0.48 per basic and diluted share, for the same period in 2022.
