SEATTLE, Aug. 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 second quarter ended June 30, 2023 and provided a corporate update.
“The first half of 2023 has been particularly productive for Icosavax, highlighted by our positive topline interim Phase 1 data and the initiation of a Phase 2 trial for IVX-A12, our potential first-in-class bivalent vaccine candidate for RSV and hMPV,” said Adam Simpson, Chief Executive Officer of Icosavax. “From our Phase 1b extension trial of IVX-121 in RSV, we recently announced positive 12-month immunogenicity and initial revaccination data; these were exciting because better durability and improved response to boosting are potential opportunities for differentiation of our VLP technology. Looking ahead we have additional near-term clinical milestones, including topline interim data from our Phase 2 study of IVX-A12 by the end of the year.”
Second Quarter 2023 and Subsequent Highlights
- Reported positive topline interim phase 1 results for bivalent VLP vaccine candidate IVX-A12 against RSV and hMPV in older adults. In May 2023, Icosavax announced positive topline interim results from a Phase 1 clinical trial of IVX-A12 against respiratory syncytial virus (RSV) and human metapneumovirus (hMPV) in older adults. IVX-A12 is comprised of IVX-121, Icosavax’s RSV prefusion F protein VLP vaccine candidate, and IVX-241, Icosavax’s hMPV prefusion F protein VLP vaccine candidate. In this Phase 1 trial, IVX-A12 induced robust immune responses against both RSV and hMPV at day 28 in older adults, with no evidence of immune interference between RSV and hMPV VLPs administered in combination, and was generally well-tolerated across all dosage groups.
- Initiated Phase 2 clinical trial of IVX-A12 against RSV and hMPV in older adults. In June 2023, Icosavax announced the initiation of a Phase 2 clinical trial of IVX-A12 in older adults. Dosing has been completed and topline interim data is now expected by the end of 2023.
- Reported positive 12-month durability data for IVX-121 against RSV and initial evidence for revaccination potential. In August 2023, Icosavax provided a 12-month immunogenicity 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. The company also reported initial evidence for revaccination potential with its VLP-based vaccines, including robust immune responses against RSV-A in Phase 1b extension trial participants who received 75 µg unadjuvanted IVX-121 at one year after their first dose.
- Completed a
$67.8 million registered direct offering of common stock. In May 2023, Icosavax closed a registered direct offering of 8,369,754 shares of its common stock at a purchase price of$8.10 per share. The$67.8 million financing was led by new investor TCGX with participation by additional new investors including Logos Capital and Vivo Capital. - Appointed Dr. M. Amin Khan, PhD as Executive Vice President, Head of Research and Development. During the quarter, Icosavax appointed Dr. M. Amin Khan as the company’s Head of Research and Development. Dr. Khan has more than 30 years’ experience in vaccine and pharmaceutical R&D, including senior scientific and executive leadership roles at Eli Lilly, Novartis and GlaxoSmithKline. He has guided scientific and technical teams to develop novel vaccines for infectious diseases including targets for RSV, influenza, meningitis, group B streptococcus, S. aureus, COPD, CMV, herpes zoster and SARS-Cov-2, and has contributed to the licensure of four vaccines.
Near-Term Milestone Expectations
- IVX-A12 (RSV + hMPV) Phase 2 topline interim data expected by end 2023
- IVX-A12 (RSV+ hMPV) Phase 1 six-month immunogenicity data expected in 1Q 2024
- Other indications: no changes to milestones related to Flu and COVID-19 programs
Second Quarter Financial Results
- Cash and cash equivalents and short-term investments as of June 30, 2023 was
$246.9 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 June 30, 2023 were
$19.9 million , compared to$15.8 million for the same period in 2022. The increase was primarily driven by increased clinical development activity, increased personnel related expenses and stock-based compensation expense, increased expenses primarily related to facilities costs, and increased development-related consulting costs, partially offset by decreased preclinical development and manufacturing activity. Research and development expenses include non-cash stock-based compensation expenses of$2.4 million for the three months ended June 30, 2023. - General and administrative (G&A) expenses for the three months ended June 30, 2023 were
$9.1 million compared to$7.3 million for the same period in 2022. The increase was primarily due to increased expenses related to facilities costs to support the company’s growth, increased stock-based compensation expense, increased professional services, 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 June 30, 2023. - Net loss for the three months ended June 30, 2023 was
$26.5 million , or a basic and diluted net loss per share of$0.59 . This includes non-cash stock-based compensation expense of$6.3 million . Net loss for the same period in 2022 was$22.6 million or a basic and diluted net loss per share of$0.57 .
