Invivyd Reports Full Year 2022 Financial Results and Business Highlights

Advancing VYD222 into clinical development based on in vitro data demonstrating neutralizing

activity against multiple important variants of concern, including XBB.1.5

Anticipate near-term designation of an additional monoclonal antibody against SARS-CoV-2

with complementary binding properties to VYD222 for development

Well capitalized with $372 million in cash, cash equivalents and marketable securities expected

to support operating runway into second half of 2024

Conference call scheduled for Thursday, March 23^rd at 4:30 p.m. ET

Waltham, MA – March 23, 2023 – Invivyd, Inc. (Nasdaq: IVVD), a clinical-stage biopharmaceutical company on a mission to protect the vulnerable from serious viral infectious diseases, today announced financial results for the year ended December 31, 2022, and recent business highlights.

“2022 was a transformational year for Invivyd as we reformed our strategy and are now squarely focused on leveraging our integrated discovery platform to advance a stream of SARS-CoV-2 monoclonal antibody (mAb) candidates. There continues to be an urgent, unmet medical need for vulnerable populations given no antibodies are currently authorized,” said Dave Hering, CEO of Invivyd. “We are pleased to have recently announced plans to advance VYD222 into clinical development as a novel mAb therapeutic option for COVID-19. We believe VYD222 is a highly attractive candidate that could potentially leverage adintrevimab’s strong clinical data package to support potential accelerated development. Importantly, in vitro data on VYD222 has shown neutralizing activity against multiple currently circulating variants of concern, including those that led to the obsolescence of products previously authorized in the U.S. We continue to plan for a Phase 1 clinical trial start in Q1 2023. Assuming positive Phase 1 data, we anticipate rapidly initiating Phase 3 pivotal trials that could support regulatory filings globally.”
