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.”

Third Quarter 2022 and Subsequent Highlights

  • Initiated Phase 1 trial of IVX-A12 against RSV and hMPV in older adults. In October, the company announced the initiation of a Phase 1 clinical trial of IVX-A12, a combination bivalent RSV and hMPV VLP vaccine candidate, 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. IVX-A12 is the first candidate from Icosavax’s novel VLP platform to receive IND authorization in the U.S. Icosavax anticipates announcing topline results from this Phase 1 trial in mid-2023, and subsequently plans to initiate a Phase 2 trial for IVX-A12 in 2H 2023.

Near-Term Milestone Expectations

  • IVX-121 (RSV) Phase 1b extension, 6-month immunogenicity data expected by early 2023
  • IVX-121 (RSV) Phase 1b extension, 12-month immunogenicity data expected in mid-2023
  • IVX-A12 (RSV+hMPV) Phase 1 topline interim data expected in mid-2023
  • IVX-A12 (RSV+hMPV) Phase 2a initiation expected in 2H 2023
  • COVID-19 bivalent candidate selection expected in 2023
  • Flu program candidate selection expected in 2023

Third Quarter Financial Results

  • Cash, cash equivalents, restricted cash, and short-term investments as of September 30, 2022 were $222.5 million, compared to $280.7 million as of December 31, 2021. 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 months ended September 30, 2022, were $15.5 million compared to $10.9 million for the same period in 2021. The increase was primarily driven by increased clinical development activity, and increased personnel related expenses and stock-based compensation expense. Research and development expenses include non-cash stock-based compensation expenses of $2.0 million for the three months ended September 30, 2022.
  • General and administrative (G&A) expenses for the three months ended September 30, 2022 were $7.7 million, compared to $25.4 million for the same period in 2021. The decrease was primarily from lower stock-based compensation expense, due to $21.0 million in one-time, non-cash stock-based compensation expense from the acceleration of options in connection with the death of the company’s former co-founder and Chairman (Tachi Yamada) in 2021, offset by increased personnel costs, increased professional services and insurance costs, and other operating expenses to support the Company’s growth. General and administrative expenses include non-cash stock-based compensation expenses of $3.4 million for the three months ended September 30, 2022.
  • Net loss for the three months ended September 30, 2022 was $22.0 million, or a basic and diluted net loss per share of $0.55. This includes non-cash stock-based compensation expense of $5.4 million. Net loss for the same period in 2021 was $34.4 million, or a basic and diluted net loss per share of $1.30.
