Assembly Biosciences Reports Fourth Quarter and Year End 2021 Financial Results and Recent Highlights
SOUTH SAN FRANCISCO, Calif., March 10, 2022 (GLOBE NEWSWIRE) -- Assembly Biosciences, Inc. (Nasdaq: ASMB), a clinical-stage biotechnology company developing innovative therapeutics targeting hepatitis B virus (HBV) and other viral diseases, today reported financial results and recent highlights for the fourth quarter and year ended December 31, 2021.
“Our expanded strategy and pipeline progress in 2021 have positioned us to reach a number of important milestones in 2022 with both our core inhibitor portfolio and our research programs beyond core inhibition and HBV,” said John McHutchison, AO, MD, chief executive officer and president of Assembly Bio. “The Phase 2 triple combination studies evaluating our lead investigational core inhibitor candidate, vebicorvir (VBR), plus standard-of care NrtI with other complementary mechanisms are progressing, and we anticipate initial on-treatment data during the second half of the year. We also plan to begin a Phase 1b trial of ABI-H3733, with initial antiviral data anticipated before year end, and to initiate clinical development of ABI-4334, our newest core inhibitor candidate that has been optimized for potency against the formation of cccDNA. Importantly, during the first half of 2022, we intend to share more about research programs underway that leverage our team’s deep virologic drug development expertise to explore new targets in HBV as well as other viral diseases. We look forward to introducing the first of these during a web event at the end this month.”
Fourth Quarter 2021 and Recent Highlights
- Announced clinical collaboration agreement with Antios Therapeutics to evaluate a triple combination of VBR + nucleos(t)ide reverse transcriptase inhibitor (NrtI) and ATI-2173, Antios’ investigational proprietary active site polymerase inhibitor nucleotide (ASPIN)
- Presented two posters and an oral presentation at AASLD The Liver Meeting™ in November 2021:
- Preclinical characterization, including single-digit nanomolar potency for ABI-4334 against both pgRNA encapsidation and cccDNA formation
- Favorable pharmacokinetics and safety in a Phase 1a study ABI-H3733
- Phase 2 open-label study data for VBR demonstrate the contribution of core inhibition to deepen viral suppression
- Presented an oral and poster presentation on Assembly Bio’s core inhibitor programs at HEP DART in December 2021
- Completed enrollment in a Phase 2 triple combination study evaluating VBR + NrtI and interferon (PEG-IFNα)

- Received EASL’s acceptance of five abstracts on Assembly Bio’s core inhibitor candidates for presentation at the International Liver Congress 2022, to be held June 22-26
2022 Anticipated Milestones and Events
- Provide updates on strategy and research programs beyond HBV core inhibition to other HBV targets and share plans to explore other viruses
- Assembly Bio will provide the first update on these research programs during a virtual event with a physician expert on Thursday, March 31 at 11:00 a.m. ET. Additional details will be announced closer to the event.
- Complete enrollment in a Phase 2 triple combination study evaluating VBR + NrtI and AB-729, Arbutus Biopharma’s RNAi therapeutic candidate
- Initiate Phase 1b study of ABI-H3733 in patients with chronic HBV infection
- Initiate triple combination cohort with VBR + NrtI and ATI-2173, Antios’ ASPIN
- Initiate first-in-human Phase 1a study of ABI-4334, a next-generation core inhibitor optimized for potency against the formation of covalently closed circular DNA (cccDNA)
- Report interim on-treatment data from two triple combination studies: (1) VBR + NrtI and AB-729 and (2) VBR + NrtI and Peg-IFNα
- Report initial Phase 1b data for ABI-H3733
- Report Phase 1a data for ABI-4334 as early as year-end
- William Delaney, PhD, chief scientific officer, will present “Discovery and Development of HBV Core Inhibitors for the Treatment of Chronic Hepatitis B Infection” during the International Conference on Antiviral Research (ICAR), on March 25, 2022.
- Luisa Stamm, MD, PhD, chief medical officer, and Katie Kitrinos, PhD, vice president clinical virology, will present during the 2nd Annual Chronic HBV Drug Development Summit, April 25-27, 2022.
Fourth Quarter 2021 and Year End Financial Results
- Cash, cash equivalents and marketable securities were $174.6 million as of December 31, 2021, compared to $190.1 million as of September 30, 2021, and $216.4 million as of the year ended December 31, 2020. This result includes $52.8 million of net proceeds from the issuance of common shares under Assembly Bio’s at-the-market (ATM) program during the year. The company’s cash position is projected to fund operations into the second half of 2023.
- Revenues from collaborative research were $6.3 million for the year ended December 31, 2021, compared to $79.1 million in 2020. The year-over-year decrease was primarily due to the $31.0 million recognized under the collaboration agreement with BeiGene, Ltd. (BeiGene) and the remaining deferred revenue balance of $37.0 million incurred under the collaboration agreement with Abbvie Inc. (Allergan Pharmaceuticals International Limited prior to Abbvie’s acquisition of Allergan) both occurring in 2020.
- Research and development expenses were $68.5 million for the year ended December 31, 2021, compared to $106.8 million in 2020. The decrease was due to a decrease of $39.0 million in research and development expenses related to the wind-down of the company’s microbiome program. Research and development expenses include non-cash stock-based compensation expenses of $0.5 million for the year ended December 31, 2021, and $11.4 million for the same period in 2020. The decrease in stock-based compensation is primarily due to a decrease in the grant date fair value of option grants and reversals in previously recognized expense related to forfeited awards of former employees.
- General and administrative expenses were $28.8 million for the year ended December 31, 2021, compared to $37.1 million in 2020. General and administrative expenses include non-cash stock-based compensation expenses of $4.7 million for the year ended December 31, 2021, and $10.5 million for the same period in 2020. The decrease in stock-based compensation is due to a decrease in the grant date fair value of recent option grants and a reversal of previously recognized expense during 2021 related to forfeited awards from former employees.
- Net loss attributable to common stockholders was $129.9 million, or $3.00 per basic and diluted share, for the year ended December 31, 2021, compared to $62.2 million, or $1.75 per basic and diluted share in 2020. Net loss for the year ended December 31, 2021 includes $41.6 million in impairment charges of our goodwill and indefinite-lived intangible asset due to a sustained decline in our stock price and a higher discount rate applied to future cash flows.
