Anticipated Milestones and Events
Nominate an additional development candidate from the expanded research portfolio in 2023
Complete IND/CTA submission for 5366 and initiate clinical studies in the first half of 2024
Advance an additional development candidate into clinical studies by year-end 2024
Upcoming Conferences
Three abstracts accepted for presentation at the 2023 International HBV Meeting taking place September 19-23, 2023, in Kobe, Japan, highlighting preclinical and in vitro data for the company’s oral, small-molecule HBV/HDV entry inhibitor program, small-molecule, liver-focused interferon alpha receptor agonist program and next-generation core inhibitor candidate 4334
Second Quarter 2023 Financial Results
Cash, cash equivalents and marketable securities were $59.8 million as of June 30, 2023, compared to $73.0 million as of March 31, 2023. Assembly Bio’s cash position is projected to fund operations through the third quarter of 2024.
Research and development expenses were $12.5 million for the three months ended June 30, 2023, compared to $17.8 million for the same period in 2022. The decrease is primarily due to prior year preclinical work and start-up costs preparing for the trials for 3733 and 4334 as well as the discontinued development of vebicorvir and ABI-H2158 and decreases in employee and contractor-related expenses.
General and administrative expenses were $5.0 million for the three months ended June 30, 2023, compared to $6.8 million for the same period in 2022. The decrease is primarily due to overall cost-saving initiatives.
Net loss attributable to common stockholders was $16.9 million, or $0.32 per basic and diluted share, for the three months ended June 30, 2023, compared to $24.5 million, or $0.51 per basic and diluted share, for the same period in 2022.
