SEATTLE, Nov. 14, 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 third quarter ended September 30, 2022 and provided a corporate update.

“The past few months have marked a pivotal moment for Icosavax, as we advanced our vision of creating combination vaccine candidates targeting respiratory diseases for older adults. Specifically, we recently initiated a Phase 1 trial for IVX-A12, which is not only our first combination VLP vaccine candidate, but also the only bivalent vaccine candidate targeting RSV and hMPV to reach clinical development,” said Adam Simpson, Chief Executive Officer of Icosavax. “As we continue to work to progress IVX-A12, we are excited by the multiple potential inflection points that are set up for next year. Notably, we anticipate the IVX-A12 Phase 1 topline interim data in mid-2023, as well as six- and twelve-month immunogenicity data from the Phase 1b extension of its RSV component IVX-121 by early- and mid-2023, respectively. In addition, during 2023 we expect to announce the selection of candidates for our COVID-19 and flu programs.”
