Assembly Biosciences Reports Third Quarter 2022 Financial Results and Recent Highlights and Announces Upcoming Conference Participation
Phase 1a Trial of Next-Generation Core Inhibitor, ABI-4334, Now Underway Following Clinical Trial Application (CTA) Clearance
SOUTH SAN FRANCISCO, Calif., Nov. 08, 2022 (GLOBE NEWSWIRE) -- Assembly Biosciences, Inc. (Nasdaq: ASMB), a clinical-stage biotechnology company developing innovative, investigational therapeutics targeting hepatitis B virus (HBV) and other viral diseases, today announced financial results and recent highlights for the third quarter ended September 30, 2022.
“During the third quarter, we have advanced clinical development of both of our next-generation, more potent core inhibitors with the Phase 1b study of 3733 on track to report initial data by the end of this year and the initiation of the first clinical study for 4334,” said John McHutchison, AO, MD, chief executive officer of Assembly Bio. “This quarter also marked the further expansion of our pipeline with the introduction of our first research programs outside of HBV and hepatitis delta virus. These programs, targeting high-recurrence genital herpes and transplant-associated herpesviruses, apply the deep expertise of our organization in small molecule antiviral drug development to develop differentiated approaches for viral diseases with significant unmet medical need. We are thrilled with the progress of our preclinical and clinical programs, and we remain encouraged about the potential for our next-generation core inhibitors with the recently presented data at AASLD and upcoming clinical data readout for 3733.”
- Received CTA clearance and initiated a blinded, placebo-controlled Phase 1a trial in New Zealand of the company’s next-generation investigational core inhibitor, ABI-4334 (4334), evaluating safety, tolerability and pharmacokinetics of single and multiple ascending doses of 4334 in healthy subjects.
- Introduced the first two new research programs expanding Assembly Bio’s portfolio beyond HBV and hepatitis delta virus (HDV):
- A long-acting herpes simplex virus type 2 (HSV-2) helicase inhibitor to treat high-recurrence genital herpes, and
- A pan-herpes non-nucleoside polymerase inhibitor to treat multiple transplant-associated herpesvirus infections.
- Announced the retirement of John McHutchison as chief executive officer (CEO) effective at the end of 2022 and the election of Jason Okazaki, currently president and chief operating officer, to succeed Dr. McHutchison as CEO and president and a member of the board of directors. Dr. McHutchison will continue to serve on the board of directors and assume the role of chair of the Science and Technology Committee.
- Presented four posters at the American Association for the Study of Liver Diseases (AASLD) The Liver Meeting®, held November 4-8, 2022, including results from Assembly Bio’s next-generation core inhibitor 4334 and the first presentations of data from the company’s HBV/HDV entry inhibitor and interferon-α receptor (IFNAR) agonist research programs:
- ABI-4334, a novel hepatitis B virus core inhibitor, accelerates capsid assembly and inhibits cccDNA formation via multiple pathways
- Preclinical characterization of a novel class of highly potent small molecule hepatitis B and D virus entry inhibitors
- Preclinical characterization of a novel liver-focused small molecule efficiently inhibiting hepatitis B virus by activating type I interferon signaling
- Evaluation of the vebicorvir, NrtI, and AB-729 combination in virologically suppressed patients with HBeAg negative chronic hepatitis B virus infection: Interim analysis from an open label Phase 2 study
- Additional Conference Participation:
- Presented at the International Workshop on HBV Cure 2022 held November 2, 2022, on “Next generation core inhibitors (capsid assembly modulators).”
- Presented at the 2022 International HBV Meeting held September 18-20, 2022, on “Next generation core inhibitors demonstrate increased potency and distinct biochemical properties compared to first-generation core inhibitors.”
- Presented at Discovery on Target 2022 held October 17-20, 2022, on “HBV core inhibitors for the treatment of chronic viral infection.”
- Mr. Okazaki and William Delaney, PhD, chief scientific officer, presented during the H.C. Wainwright 3rd Annual HBV Virtual Conference held October 18, 2022.
- Dr. McHutchison presented during the H.C. Wainwright 24th Annual Global Investment Conference held September 12-14, 2022.
Anticipated Milestones and Events
- Initial Phase 1b data for ABI-H3733 (3733) in 2H 2022.
- Full Phase 1b data for 3733 in 1H 2023.
- Full Phase 1a data for 4334 in 1H 2023.
- Two development candidate nominations from Assembly Bio’s expanded research portfolio in 2023.
- Mr. Okazaki and Dr. Delaney will present in a fireside chat during the Jefferies London Healthcare Conference at 5:35 p.m. GMT on November 15, 2022. A live webcast will be available on the Events and Presentations section of Assembly Bio’s website and a replay will be accessible following the event.

Third Quarter 2022 Financial Results
- Cash, cash equivalents and marketable securities were $108.7 million as of September 30, 2022, compared to $128.6 million as of June 30, 2022. The company’s cash position is projected to fund operations into the first half of 2024.
- Research and development expenses were $18.1 million for the three months ended September 30, 2022, compared to $18.5 million for the same period in 2021. The decrease is primarily due to the discontinued development of ABI-H2158 and VBR, partially offset by increases in our 3733, 4334, and research and discovery programs.
- General and administrative expenses were $5.3 million for the three months ended September 30, 2022, compared to $6.7 million for the same period in 2021. The decrease is primarily due to a decrease in professional fees.
- Net loss attributable to common stockholders was $23.1 million, or $0.48 per basic and diluted share, for the three months ended September 30, 2022, compared to $18.8 million, or $0.41 per basic and diluted share, for the same period in 2021.
