SEATTLE, March 30, 2022 (GLOBE NEWSWIRE) -- Icosavax, Inc. (Nasdaq: ICVX), a biopharmaceutical company leveraging its innovative virus-like particle (VLP) platform technology to develop vaccines against infectious diseases, with an initial focus on life-threatening respiratory diseases and a vision of creating pan-respiratory vaccines for older adults, today reported financial results for the fourth quarter and full year ended December 31, 2021 and provided a corporate update.
“Despite the recent readout for IVX-411, I am pleased with the progress we achieved in 2021, including our successful initial public offering and advancing two programs into the clinic,” said Adam Simpson, Chief Executive Officer of Icosavax. “We continue to progress and evaluate our VLP vaccine candidates for multiple indications, and in particular look forward to the 2Q 2022 topline interim data from our lead program, IVX-121 against RSV. RSV represents a significant commercial opportunity, and the readout provides the company with a near-term potential milestone that may also serve as clinical proof of concept for our VLP platform. Contingent on positive data from that trial, we plan to then initiate a Phase 1 study of our first combination vaccine candidate, IVX-A12, for RSV and human metapneumovirus during 2H 2022.”
Fourth Quarter 2021 and Subsequent Highlights
- Announced topline interim Phase 1/2 data for IVX-411 against SARS-CoV-2. In March, Icosavax reported topline, interim data for IVX-411, a VLP vaccine candidate displaying the SARS-CoV-2 receptor-binding domain (RBD). Immunologic response was observed in both SARS-CoV-2 naive and previously vaccinated subjects, but at lower than expected levels that were inconsistent with known data about VLPs, including from clinical studies in COVID-19 and the company’s own preclinical data. As a result, the company is conducting an end-to-end drug product investigation to better understand the results and determine a path forward for the COVID-19 program.
- Initiated influenza program. Icosavax licensed the rights to develop and commercialize an influenza VLP vaccine from the University of Washington, as the company executes on its strategy to develop combination VLP vaccines targeting the viral causes of pneumonia in older adults. The company has initiated preclinical development of a quadrivalent, VLP influenza vaccine candidate.
- Appointed John Shiver, Ph.D., to Board of Directors, and Robin Robinson, Ph.D. to Scientific Advisory Board (SAB). In January, Dr. Shiver was appointed to Icosavax’s Board of Directors. Dr. Shiver has more than 30 years of experience in vaccine and pharmaceutical research, having guided scientific teams to create novel vaccine and monoclonal antibody candidates to prevent or treat more than 40 infectious and non-infectious diseases. Icosavax also expanded its SAB with the addition of Dr. Robinson, who previously served for eight years as the first Director for the Biomedical Advanced Research and Development Authority (BARDA) and before that was Head of Vaccines at Novavax, Inc.
- Data published on prefusion hMPV antigen being advanced as part of IVX-A12, a combination bivalent RSV and human Metapneumovirus (hMPV) VLP vaccine candidate. Nature Communications published new data showing that a prefusion form of the hMPV antigen elicits a six-fold greater immune response in mice versus the postfusion form. Icosavax has exclusively licensed rights to this prefusion stabilized F antigen (except for one mRNA license that may be granted) and incorporated the stabilizing mutations into a VLP-based antigen.
Near-Term Milestone Expectations
- IVX-121 (RSV) Phase 1/1b topline interim data expected in 2Q 2022
- Provide update on IVX-411 (Covid) following company’s end-to-end investigation
- IND submission for IVX-A12 (RSV+hMPV) and initiation of a Phase 1 trial for IVX-A12 expected in 2H 2022
Fourth Quarter and Full Year 2021 Financial Results
- Cash and restricted cash as of December 31, 2021 was $280.7 million, compared to $15.5 million for the period ended December 31, 2020. Icosavax currently expects its cash balance to be sufficient to fund operations through at least 2024.
- Research and development (R&D) expenses for the three and twelve months ended December 31, 2021 were $14.1 million and $38.8, respectively, compared to $5.2 million and $17.7 for the same period in 2020, respectively. The increase was primarily driven by increased clinical development and manufacturing costs, growth in the number of R&D employees, including increased stock-based compensation expense, and increased preclinical development and manufacturing activity. Research and development expenses include non-cash stock-based compensation expense of $1.2 million and $2.7 million for the three and twelve months ended December 31, 2021, respectively.
- General and administrative (G&A) expenses for the three and twelve months ended December 31, 2021 were $6.2 million and $34.9, respectively, compared to $0.8 million and $2.7 for the same period in 2020, respectively. The increase was primarily due to growth in the number of G&A employees, including increased stock-based compensation expense, and increased professional services and other operating expenses to support the company’s growth. The increased stock-based compensation for the twelve months ended December 31, 2021 is inclusive of $21.0 million in one-time, non-cash expense from the acceleration of options in connection with the death of the company’s former co-founder and Chairman (Tachi Yamada). General and administrative expenses include non-cash stock-based compensation expense of $2.4 million and $26.3 million for the three and twelve months ended December 31, 2021, respectively.
- Net loss for the three and twelve months ended December 31, 2021 was $18.2 million and $67.0 million, respectively, or a basic and diluted net loss per share attributable to common stockholders of $0.46 and $3.73, respectively. This includes non-cash stock-based compensation expense of $29.0 million. Net loss for the same period in 2020 was $4.6 million and $18.9 million, respectively, or a basic and diluted net loss per share attributable to common stockholders of $1.28 and $8.40, respectively.
Icosavax is a biopharmaceutical company leveraging its innovative VLP platform technology to develop vaccines against infectious diseases, with an initial focus on life-threatening respiratory diseases and a vision for combination and pan-respiratory vaccines. Icosavax’s VLP platform technology is designed to enable multivalent, particle-based display of complex viral antigens, which it believes will induce broad, robust, and durable protection against the specific viruses targeted. Icosavax’s pipeline includes vaccine candidates targeting respiratory syncytial virus (RSV), human metapneumovirus (hMPV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and an emerging program in influenza. Icosavax was formed in 2017 to advance the breakthrough VLP technology from the Institute for Protein Design at the University of Washington with the goal to discover, develop, and commercialize vaccines against infectious diseases. Icosavax is located in Seattle.
