Assembly Biosciences Announces Third Quarter 2018 Financial Results and Provides HBV Program Update


ABI-H0731 Phase 2a Clinical Trials Actively Enrolling Patients; Data Continues to be Anticipated in 1H 2019

ABI-H2158 Phase 1a Study Initiated

ABI-H3733 Nominated as Third Core Inhibitor Candidate

SAN FRANCISCO, Nov. 08, 2018 (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 for the third quarter ended September 30, 2018 and provided an update on the progress in its HBV and microbiome pipelines.

“We are excited about the advancements we have made in our HBV portfolio, with two core inhibitors now in clinical trials and the selection of a third potent, novel clinical candidate,” said Derek Small, President and Chief Executive Officer. “With the nomination of ABI-H3733 as our third candidate, we have a deep pipeline of HBV core inhibitors in development and continue our discovery efforts focused on identifying additional chemical scaffolds. We are actively enrolling patients in our ongoing ABI-H0731 Phase 2a proof-of-concept studies, and our team is committed to advancing potential curative therapy to HBV patients. Our microbiome platform has also made great strides over the past quarter and pending the successful conclusion of IND-enabling studies, we hope to have our first candidate ABI-M201 for ulcerative colitis in the clinic next year. Importantly, our strong balance sheet supports our development plans through multiple inflection points.”

Third Quarter and Recent Highlights

• Assembly continued enrolling patients in two Phase 2a studies evaluating ABI-H0731, the Company’s lead HBV core inhibitor. The Phase 2a viral antigen proof-of-concept study was recently expanded to include an additional cohort of virus suppressed HBeAg negative patients. The addition of this cohort is not expected to significantly impact enrollment timelines and will further Assembly’s understanding of outcomes in different patient populations as well as aid in the design of potential registrational studies.

• Assembly initiated a Phase 1a dose-ranging clinical trial of ABI-H2158, the Company’s second, highly potent core inhibitor, in healthy volunteers.

• Assembly has nominated its third core inhibitor candidate, ABI-H3733, derived from a new chemical class distinct from Assembly’s other core inhibitors in development. In nonclinical studies, ABI-H3733 has exhibited superior potency while maintaining good drug-like properties. ABI-H3733 is currently undergoing investigational new drug (IND) enabling studies.

• Microbiome candidate ABI-M201 (partnered with Allergan) is currently completing IND-enabling studies and is expected to enter the clinic in 2019 in patients with mild to moderate ulcerative colitis.

Anticipated Milestones and Events

• ABI-H0731

  • Final Phase 1b data will be presented at the American Association for the Study of Liver Diseases Annual Meeting (AASLD) on Sunday, November 11, 2018 in San Francisco by MF Yuen, MD, PhD, Chief of Division of Gastroenterology and Hepatology, Queen Mary Hospital, Hong Kong.
  • Interim Phase 2a data is expected in the first half of 2019.

• ABI-H2158

  • Interim Phase 1a data expected in mid 2019.

• ABI-M201

  • Initiate Phase 1b clinical study in 2019 in patients with mild to moderate ulcerative colitis.

• Upcoming events

  • AASLD,  San Francisco, November 9-13, 2018
  • Jefferies London Healthcare Conference, November 14-15, 2018
  • Global Mizuho Investor Conference in New York, December 3-4, 2018

Third Quarter Financial Results

Cash, cash equivalents and marketable securities were approximately $233.9 million as of September 30, 2018 compared to approximately $94.9 million as of June 30, 2018.

Revenues consisting of revenue from collaborative research were approximately $4.3 million for the three months ended September 30, 2018, compared to approximately $2.7 million for the same period in 2017. The increase in revenue was due to an increase in Allergan-related activities and expense reimbursement.

Research and development expenses, excluding stock-based compensation expense, were approximately $16.6 million for the three months ended September 30, 2018, compared to approximately $9.4 million for the same period in 2017. This increase was primarily due to an increase of approximately $5.5 million in research and development expenses related to the HBV program and an increase of approximately $1.6M in research and development expenses related to the microbiome program. Stock-based compensation expense was approximately $2.5 million for the three months ended September 30, 2018, compared to approximately $1.6 million for the same period in 2017.

General and administrative expenses, excluding stock-based compensation expense, were approximately $4.2 million for the three months ended September 30, 2018, compared to approximately $3.1 million for the same period in 2017. This increase was primarily due to increased headcount across the organization.  Stock-based compensation expense was approximately $3.5 million for the three months ended September 30, 2018, as compared to $1.0 million for the same period in 2017.

Net loss attributable to common stockholders was approximately $21.5 million, or $0.87 per basic and diluted share, for the three months ended September 30, 2018, compared to approximately $12.3 million, or $0.71 per basic and diluted share for the same period in 2017. This increase was primarily due to an increase in research and development expenses related to the HBV program, and expenses related to non-cash, stock-based compensation, employee incentive programs and increased headcount across the organization.
