SOUTH SAN FRANCISCO, Calif., March 04, 2020 (GLOBE NEWSWIRE) — Assembly Biosciences, Inc. (NASDAQ: ASMB), a clinical-stage biotechnology company developing innovative therapeutics targeting hepatitis B virus (HBV) and diseases associated with the microbiome, today reported financial results and recent highlights for the fourth quarter and year ended December 31, 2019. “We closed out 2019 with exciting Phase 2 data from our HBV core inhibitor program at AASLD, where ABI-H0731 showed superior antiviral activity to nucleos(t)ide therapy alone as well as significant declines in pgRNA that we believe are reflective of decreases in cccDNA levels. With these encouraging findings and input from our investigators, we are finalizing plans to this year begin transitioning patients meeting certain criteria off 731+Nrtl therapy in the ongoing extension study, to observe if viral suppression can be sustained,” said John McHutchison, AO, MD, Chief Executive Officer and President. “Importantly, we begin 2020 well-resourced to advance our strategy and pipeline. During the fourth quarter we further strengthened our senior leadership team with the appointments of our Chief Financial Officer, our Chief Medical Officer and our Senior Vice President of Regulatory Affairs. With our experienced and dedicated team and a strong balance sheet following our successful December equity offering, we are well positioned to move our lead HBV candidate toward registration studies, to advance our second generation HBV candidate into Phase 2, and to further progress our microbiome program. We are also pleased to note that abstracts from both our HBV and microbiome therapeutic programs will be featured in presentations at medical meetings during the second quarter of 2020.”Fourth Quarter 2019 and Recent HighlightsAt the American Association for the Study of Liver Diseases (AASLD) Annual Meeting in November 2019, Assembly presented final 24-week data from two Phase 2 studies (201 and 202) and interim data from the ongoing Phase 2 long-term extension study (211) of ABI-H0731 (731), as well as interim data from the Phase 1b study of ABI-H2158 (2158).
° 731 + nucleos(t)ide analogs (NrtI) in HBeAg positive patients with chronic Hepatitis B infection demonstrated favorable longer-term safety and tolerability, greater reductions in HBV DNA and HBV pgRNA than in NrtI alone. Data also showed that significant declines in HBV pgRNA, a primary surrogate marker of cccDNA, were associated with reductions in hepatitis B viral antigens (HBeAg, HBcrAg and HBsAg)
° Interim data from the ongoing Phase 1b study of 2158 demonstrated potent antiviral activity and tolerability in the initial low dose cohort of 100 mg in HBeAg-positive patients treated for 14 days. The study is ongoing, and the company expects to report data on higher dose cohorts in Q2 2020.Abstracts featuring data from Assembly’s HBV portfolio have been accepted for presentation at the International Liver Congress (EASL) in London, April 15-19, 2020.An abstract featuring preclinical data from Assembly’s microbiome therapeutics program focused on ulcerative colitis has been accepted for poster presentation during Digestive Disease Week in Chicago, May 2-5, 2020, and an abstract featuring preclinical data from Assembly’s proprietary oncology microbiome therapeutics program has also been accepted for a poster presentation during the American Association for Cancer Research Annual Meeting in San Diego, April 24-29, 2020. Assembly strengthened its balance sheet with an underwritten public offering that closed in December 2019 and resulted in net proceeds of $134.7 million.Upcoming Milestones

This year end cash position is projected to fund operations into 2022.
Revenues from collaborative research were $4.8 million for the three months ended December 31, 2019 compared to $3.7 million for the same period in 2018, and $16.0 million for the year ended December 31, 2019 compared to $14.8 million in 2018. The increase was related to an increase in research and development efforts for our microbiome program, including the initiation of a Phase 1b study.
Research and development expenses, excluding stock-based compensation expense, were $19.6 million for the three months ended December 31, 2019, compared to $18.1 million for the same period in 2018, and $74.4 million for the year ended December 31, 2019 compared to $60.9 million for the year ended December 31, 2018. This increase was primarily due to an increase of $9.4 million in research and development expenses related to the HBV program and an increase of $4.1 million in gross research and development expenses related to the microbiome program. Stock-based compensation expense was $3.1 million for the three months ended December 31, 2019 compared to $3.1 million for the same period in 2018 and $11.4 million for the year ended December 31, 2019 as compared to $11.8 million in 2018.
General and administrative expenses, excluding stock-based compensation expense, were $7.4 million for the three months ended December 31, 2019 compared to $6.3 million for the same period in 2018, and $23.7 million for the year ended December 31, 2019 compared to $18.1 million in 2018. The increase was primarily due to increased headcount and a one-time expense for severance packages in conjunction with the relocation of the corporate headquarters to South San Francisco. Stock-based compensation expense was $3.4 million for the three months ended December 31, 2019 compared to $3.7 million for the same period in 2018 and $9.2 million for the year ended December 31, 2019 as compared to $16.7 million in 2018. This decrease was primarily due to a one-time expense incurred in 2018 coupled with the reversal in 2019 of previously recognized 2018 expenses related to the departures of two executive officers in 2018 and 2019, respectively.
Net loss attributable to common stockholders was $27.1 million, or $0.99 per basic and diluted share, for the three months ended December 31, 2019 compared to $26.1 million, or $1.03 per basic and diluted share, for the same period in 2018. For the year ended December 31, 2019, net loss was $97.6 million, or $3.72 per basic and diluted share, compared to $90.8 million, or $3.98 per basic and diluted share, for the year ended December 31, 2018.About Assembly Biosciences
