WALTHAM, Mass., Sept. 11, 2023 (GLOBE NEWSWIRE) -- Invivyd, Inc. (Nasdaq: IVVD), a clinical-stage biopharmaceutical company on a mission to protect the vulnerable from serious viral infectious diseases, today announced that the first participant has been dosed in the CANOPY Phase 3 pivotal clinical trial of VYD222, a broadly neutralizing, half-life extended monoclonal antibody, for the prevention of symptomatic COVID-19. This clinical trial is designed to rapidly generate the clinical data needed to support a potential emergency use authorization (EUA) submission for VYD222. CANOPY is expected to enroll approximately 750 participants in two cohorts (A and B) including 300 individuals who are significantly immunocompromised.

“The initiation of the CANOPY pivotal clinical trial marks a major milestone for Invivyd, and it is a significant step in our journey to rapidly advance VYD222 toward a potential EUA submission,” said Dave Hering, Chief Executive Officer of Invivyd. “Thanks to the hard work and dedication of our teams, Invivyd is at the forefront of advancing new therapeutics to address circulating viral threats. With our proprietary database of potentially eligible individuals and a Day 28 primary efficacy endpoint in the immunocompromised cohort, we expect CANOPY to enroll quickly, and we remain on track to have initial primary endpoint data around year end.”

Commenting on the milestone, Pete Schmidt, M.D., M.Sc., Chief Medical Officer at Invivyd added, “In recent months we have seen both the number of COVID-19 cases and disease related hospitalizations increase at an alarming rate in vulnerable populations. It is clear COVID-19 is going to remain a major global health concern for the foreseeable future, and this increase comes at a time when immunocompromised individuals have limited options for the prevention of symptomatic COVID-19. It is this urgent public health need that drives us to advance important new therapeutics like VYD222 as quickly as possible.”

About CANOPY  

The CANOPY pivotal clinical trial is a Phase 3 clinical trial designed to evaluate protection against symptomatic COVID-19 after receiving VYD222. The safety, tolerability, pharmacokinetic profile, and immunogenicity of VYD222 will also be evaluated. The clinical trial is expected to enroll approximately 750 participants in two cohorts (A and B) running in parallel across multiple trial sites in the U.S. Cohort A is expected to enroll approximately 300 participants who are significantly immunocompromised. For this cohort, the company will use serum neutralizing titers against relevant SARS-CoV-2 variants at Day 28 as the primary efficacy endpoint. The primary efficacy analysis will use an immunobridging approach comparing data obtained in the CANOPY clinical trial to certain historical data from the company’s previous Phase 2/3 clinical trial of adintrevimab for the prevention of symptomatic COVID-19, in which serum neutralizing titers correlated with observed clinical efficacy. All Cohort A participants will receive VYD222 administered via intravenous (IV) infusion. 

Cohort B will enroll approximately 450 participants at risk of exposure to SARS-CoV-2. The primary endpoint is safety and tolerability. Cohort B participants will be randomized 2:1 to receive VYD222 or placebo administered via IV infusion. 

Invivyd is evaluating the 4500 mg dose of VYD222 in the CANOPY trial. The company expects to have initial primary endpoint data by late 2023 or early Q1 2024. 

About VYD222

VYD222 is a broadly neutralizing, half-life extended monoclonal antibody (mAb) candidate in development for the prevention of symptomatic COVID-19 in vulnerable populations, such as immunocompromised people. Globally, there are millions of immunocompromised people, with an estimated 8-18 million in the U.S. alone, who may not adequately respond to COVID-19 vaccination, increasing their risk for severe outcomes from COVID-19. Currently, there are no monoclonal antibodies authorized or approved in the U.S. for the prevention of symptomatic COVID-19. VYD222 was designed for broad activity and has demonstrated in vitro neutralizing activity against various pre-Omicron and Omicron variants, such as XBB.1.5 and XBB.1.5.10, an Omicron variant that has the same mutations in the spike protein as EG.5. VYD222 was engineered from adintrevimab, Invivyd’s investigational mAb that has a robust safety data package and demonstrated clinically meaningful results in global Phase 2/3 clinical trials for both the prevention and treatment of COVID-19.
