SOUTH SAN FRANCISCO, Calif., Nov. 04, 2021 (GLOBE NEWSWIRE) -- Assembly Biosciences, Inc. (Nasdaq: ASMB), a clinical-stage biotechnology company developing innovative therapeutics targeting hepatitis B virus (HBV), today reported financial results and recent highlights for the third quarter ended September 30, 2021.

John McHutchison, AO, MD, chief executive officer and president of Assembly Bio, said, “We are excited to advance our latest core inhibitor ABI-4334, with a potential best-in-class profile, and we are working quickly and diligently to move this candidate into clinical development as soon as possible next year. In parallel, we have expanded evaluation of triple combination regimens to treat HBV, which include the potential backbone therapy of our lead investigational core inhibitor candidate vebicorvir (VBR) plus standard-of-care nucleos(t)ide reverse transcriptase inhibitor (Nrtl) therapy together with an additional complementary mechanism. Our two ongoing Phase 2 studies include interferon (peg-IFNα) and Arbutus’ RNAi therapeutic candidate, and we look forward to initiating a third Phase 2, all-oral triple combination cohort with Antios’ ASPIN, ATI-2173. We anticipate initial data from all three of these studies during 2022. Meanwhile, we are pleased to feature our science and portfolio at scientific and clinical meetings, demonstrating our commitment to pursuing finite and curative therapies for the more than a quarter of a billion individuals living with chronic HBV infection worldwide.”

Recent Updates

  • ABI-4334, a next-generation core inhibitor candidate that has been optimized for potency against the formation of cccDNA, was selected for advancement into clinical development. The company is conducting preclinical work, with the aim of completing regulatory filings and initiating a clinical study as soon as possible in 2022.

  • Enrollment and dosing continue in two Phase 2 triple combination studies evaluating Assembly Bio’s lead core inhibitor candidate, VBR + Nrtl therapy along with Arbutus Biopharma’s RNAi therapeutic candidate, AB-729, and separately with peg-IFNα.

  • A clinical collaboration agreement was announced with Antios Therapeutics to evaluate a triple combination of VBR + NrtI and ATI-2173, Antios’ investigational proprietary active site polymerase inhibitor nucleotide (ASPIN) in a ten patient cohort.

  • Further development of ABI-H2158 (2158) was discontinued following the observation of elevated alanine aminotransferase (ALT) levels consistent with drug-induced hepatotoxicity in a Phase 2 trial. The decision reflects the company’s strategy of advancing the candidates that exhibit the strongest safety and efficacy profiles for later-stage clinical studies.

  • William Delaney, PhD, chief scientific officer, highlighted Assembly Bio’s approach and core inhibitor portfolio during recent scientific conferences focused on HBV.

Anticipated Milestones and Events

  • Interim on-treatment data from triple combination studies with VBR + NrtI, and complementary mechanisms RNAi and peg-IFNα anticipated during 2022

  • Initiate triple combination cohort with VBR + NrtI and ATI-2173 in H1 2022 with 12-week on-treatment data expected by year-end 2022

  • Initiate Phase 1b study in ABI-H3733 in 2022

  • Complete regulatory filings for ABI-4334 and initiate clinical development during 2022

Upcoming Conferences

  • Three abstracts, including one late-breaking submission, will be presented at the annual meeting of the American Association for the Study of Liver Diseases (AASLD), The Liver Meeting Digital Experience™ (TLMdX), being hosted virtually November 12-15, 2021

  • Luisa Stamm, MD, PhD, chief medical officer, will present during the International Workshop on HBV Cure 2021, November 10, 2021 at 11 am ET

  • Jefferies London Healthcare Conference. A webcast of the fireside chat will be available in the “Events and Presentations” page in the “Investors” section of the company’s website at www.assemblybio.com on November 18, 2021 at 8:00 am GMT

  • William Delaney, PhD, chief scientific officer, will present “Development of HBV Core Inhibitors for the treatment of Chronic Hepatitis B Infection” during HEP DART 2021, December 7, 2021 at 5:45 - 7:30 pm MST

Third Quarter 2021 Financial Results

  • Cash, cash equivalents and marketable securities were $190.1 million as of September 30, 2021, compared to $199.1 million as of June 30, 2021. This result includes the $10.1 million of net proceeds from the issuance of common shares under Assembly Bio’s at-the-market (ATM) program. 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 three months ended September 30, 2021, compared to $34.6 million for the same period in 2020. Revenue for the three months ended September 30, 2021, consists of deferred revenue allocated to 2158 under the collaboration agreement with BeiGene following the announcement that Assembly Bio discontinued development of the candidate. The decrease year-over-year is due to the recognition of the amount allocated to VBR as revenue in Q3 2020 upon entering into the BeiGene agreement as well as the termination of the microbiome collaboration agreement with Allergan following AbbVie Inc.’s acquisition of Allergan. In Q1 2021 Assembly Bio completed the wind-down of its microbiome program.

  • Research and development expenses were $18.5 million for the three months ended September 30, 2021, compared to $26.9 million for the same period in 2020. The decrease is primarily due to a decrease of $8.3 million related to the wind-down of the microbiome program. Research and development expenses include non-cash stock-based compensation expenses of $1.1 million for the three months ended September 30, 2021, and $2.8 million for the same period in 2020. The decrease is primarily due to a decrease in the fair value of equity grants as well as a decrease in headcount and outstanding awards resulting from the wind-down of the microbiome program.

  • General and administrative expenses were $6.7 million for the three months ended September 30, 2021, compared to $11.7 million for the same period in 2020. General and administrative expenses include non-cash stock-based compensation expenses of $0.5 million for the three months ended September 30, 2021, and $3.3 million for the same period in 2020. The decrease is due to a decrease in the fair value of equity grants as well as a reversal of previously recognized expenses related to the forfeited awards to a former officer.

  • Net loss attributable to common stockholders was $18.8 million, or $0.41 per basic and diluted share, for the three months ended September 30, 2021, compared to $3.3 million, or $0.09 per basic and diluted share, for the same period in 2020. The increase was due to less revenue being recognized under the company’s collaboration agreements to offset expenses in 2021.
