SEATTLE, Nov. 14, 2023 (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 third quarter ended September 30, 2023 and provided a corporate update.
“We are pleased with our clinical data updates and continued pipeline progress this year. IVX-A12, our potential first-in-class combination vaccine candidate for RSV and hMPV, could address a significant unmet need and represent a large market opportunity for the company,” said Adam Simpson, Chief Executive Officer of Icosavax. “Our Phase 2 study for IVX-A12 remains on track to report topline interim results by the end of 2023, and our Phase 1 six-month durability data in the first quarter of 2024 gives us another opportunity to show a potentially differentiated profile for our VLP-based technology. In addition, we today announced candidate selection for our SARS-CoV-2 and influenza programs. While we are not pursuing further development of these candidates at this time, they provide strategic optionality for potential future pan-respiratory vaccines and also highlight our company’s antigen design capabilities.”
Third Quarter 2023 and Subsequent Highlights
- Completed candidate selection milestones for SARS-CoV-2 and influenza. In SARS-CoV-2, Icosavax has identified a generalizable RBD design that can improve stability, antigenicity, and expression levels of RBD antigens from diverse variants, including the original ancestral strain, BA.1, BA.5, and XBB. When immunogenicity was tested in the context of the BA.5 strain, the modified RBD antigen induced robust neutralizing antibody titers in a mouse model while the native unmodified antigen did not. In influenza, the company has selected both a QIV hemagglutinin (HA) candidate demonstrating robust hemagglutination inhibition and neutralizing antibody titer data against matched strains, and a neuraminidase (NA) prototype candidate with strain-independent antigen design blueprints that can be used to produce stable and immunogenic NA antigens from all current seasonal subtypes and lineages. Preclinical data show that when the company combines a designed NA antigen with a quadrivalent HA VLP, robust titers are generated against both HA and NA from the same vaccine. Icosavax has now achieved its near-term objective for these two programs.
- Presenting the company’s antigen design capability at upcoming World Vaccine & Immunotherapy Congress West Coast. Icosavax will be presenting on November 29, 2023, at 12:50 pm PT in a talk entitled, “From computationally designed antigens to VLP-based antigen display – a recipe for best-in-class vaccines.” The presentation will be made by Dr. Daniel Ellis, Senior Scientist Computational Discovery, Icosavax.
- Reported positive 12-month durability data for IVX-121 against RSV and initial evidence for revaccination potential. In August 2023, Icosavax provided an update from its Phase 1b extension trial of IVX-121 against RSV in older adults. These data demonstrate substantial durability of neutralizing antibody (NAb) response against RSV at twelve months after a single administration of IVX-121, and initial evidence for revaccination potential with its VLP-based vaccines, including robust immune responses against RSV-A in participants who received 75 µg unadjuvanted IVX-121 at one year after their first dose.
- Appointed Dr. Antu Dey as Senior Vice President, Preclinical Research and Development. Icosavax recently appointed Antu Dey, PhD as the company’s Senior Vice President of Preclinical R&D. He has more than 15 years of industry experience in discovery and early development of novel vaccine and biologic candidates against multiple infectious disease targets. Prior to Icosavax, Antu held roles of increasing responsibility at GreenLight Biosciences, International Aids Vaccines Initiative (IAVI), Novartis Vaccines & Diagnostics, and GSK Vaccines.
Near-Term Milestone Expectations
- IVX-A12 (RSV + hMPV) Phase 2 topline interim data expected by end of 2023
- IVX-A12 (RSV+ hMPV) Phase 1 six-month immunogenicity data expected in 1Q 2024
Third Quarter Financial Results
- Cash and cash equivalents and short-term investments as of September 30, 2023 was $229.2 million, compared to $219.4 million for the period ended December 31, 2022. Icosavax currently expects its cash balance to be sufficient to fund operations into 2H 2025.
- Research and development (R&D) expenses for the three months ended September 30, 2023 were $16.7 million, compared to $15.5 million for the same period in 2022. The increase was primarily driven by increased personnel related expenses and stock-based compensation expense. Research and development expenses include non-cash stock-based compensation expenses of $2.7 million for the three months ended September 30, 2023.
- General and administrative (G&A) expenses for the three months ended September 30, 2023 were $8.6 million compared to $7.7 million for the same period in 2022. The increase was primarily due to increased stock-based compensation expense and growth in the number of G&A employees. General and administrative expenses include non-cash stock-based compensation expenses of $3.9 million for the three months ended September 30, 2023.
- Net loss for the three months ended September 30, 2023 was $22.0 million, or a basic and diluted net loss per share of $0.44. This includes non-cash stock-based compensation expense of $6.6 million. Net loss for the same period in 2022 was $22.0 million or a basic and diluted net loss per share of $0.55.
About Icosavax
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 and antigen design capabilities 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 lead program is a combination vaccine candidate targeting respiratory syncytial virus (RSV) and human metapneumovirus (hMPV). Its pipeline includes additional candidates that provide optionality as potential components of future combination and pan-respiratory vaccines, including influenza and SARS-CoV-2, and the company may also develop candidates in other areas of unmet need where VLP vaccines have the potential to offer differentiated benefits. 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.
