• EUA submission is based on positive initial results from the ongoing CANOPY Phase 3 pivotal clinical trial and ongoing in vitro neutralization activity against relevant SARS-CoV-2 variants
• VYD222 demonstrates continued in vitro neutralization activity against major SARS-CoV-2 variants, including JN.1, currently the fastest growing variant in the U.S.
• Company continues preparations for potential commercial launch if EUA is granted

WALTHAM, Mass., Jan. 03, 2024 (GLOBE NEWSWIRE) -- Invivyd, Inc. (Nasdaq: IVVD), a biopharmaceutical company on a mission to protect the vulnerable from serious viral infectious diseases, today announced that it has requested Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration (FDA) for VYD222, a broadly neutralizing, half-life extended monoclonal antibody candidate, for the pre-exposure prevention of COVID-19 in immunocompromised adults and adolescents. The EUA submission was based on positive initial results from the CANOPY Phase 3 pivotal clinical trial of VYD222, as well as ongoing in vitro neutralization activity against relevant variants such as JN.1.

"We are tremendously pleased by the fact that VYD222 continues to demonstrate in vitro neutralization activity against the latest dominant variant, JN.1, as well as other prevalent SARS-CoV-2 strains,” said Dave Hering, Chief Executive Officer of Invivyd. “We believe that the demonstrated durability of VYD222 is reflective of our strategy to select antibody candidates that target conserved epitopes to achieve our stated goal of keeping pace with viral evolution.”  

Mr. Hering added, “The submission of the EUA request for VYD222 represents an exciting milestone for Invivyd that was only made possible thanks to the unwavering dedication of our employees, the support of our investigators, and the invaluable contributions of all those who participated in the CANOPY trial. Many immunocompromised people do not achieve full benefit from COVID-19 vaccines as their immune systems are unable to provide sufficient defense against SARS-CoV-2. If authorized, we believe VYD222 could provide these vulnerable individuals with an important new preventive option.”

Seth Ginsberg, President and Co-Founder, Global Healthy Living Foundation, commented, "We are eagerly tracking the progress of new monoclonal antibodies because there are still countless immunocompromised people who remain vulnerable to the ravages of COVID-19. Sustained innovation is what is needed to keep pace with this virus, and we commend Invivyd and others working in this space for their commitment and dedication to serving those who are in urgent need of protection."

On December 18, 2023, Invivyd announced positive initial results from the ongoing CANOPY pivotal clinical trial. VYD222 produced high serum virus neutralizing antibody (sVNA) titer levels against XBB.1.5 in the immunocompromised cohort. The company observed an encouraging, potential early signal of strong clinical protection from symptomatic COVID-19 in CANOPY, which would be expected based on the high sVNA titer levels and dose selected. In addition, the company believes that the initial results from CANOPY support an immunobridging approach which utilizes in vitro VYD222 potency data to calculate and efficiently determine the sVNA titer levels against new SARS-CoV-2 variants as they emerge. Initial results showed that the safety and tolerability profile of VYD222 remained favorable with no study drug related serious adverse events reported; adverse events attributed to VYD222 were Grade 1 or 2 (mild or moderate) in severity.

In vitro pseudovirus testing shows that VYD222 has potency against various SARS-CoV-2 variants currently circulating, including JN.1, which is currently the fastest growing variant in the U.S., as well as HV.1, BA.2.86, XBB.1.5.10/EG.5, and HK.3.

If authorized, Invivyd aims to have VYD222 commercially available rapidly thereafter.

About CANOPY

The CANOPY pivotal clinical trial is an ongoing 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. In November 2023, Invivyd announced the completion of enrollment in the CANOPY clinical trial, with approximately 750 participants enrolled in two cohorts (A and B) across multiple trial sites in the U.S. Cohort A enrolled approximately 300 participants who are significantly immunocompromised. For this cohort, the primary endpoints include safety and tolerability and serum neutralizing titers against relevant SARS-CoV-2 variants at Day 28, which will be calculated based on the pharmacokinetic concentration of VYD222 from the immunocompromised participants and the IC50 value for VYD222 against relevant SARS-CoV-2 variants. The primary efficacy analysis uses 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 (ADG20) for the prevention of symptomatic COVID-19 (EVADE), in which serum neutralizing titers correlated with observed clinical efficacy. All Cohort A participants received VYD222 administered via intravenous (IV) infusion. 

Cohort B enrolled approximately 450 participants at risk of exposure to SARS-CoV-2. Participants were randomized 2:1 to receive VYD222 or placebo administered via IV infusion. The primary endpoints include safety and tolerability and the proportion of participants with RT-PCR-confirmed symptomatic COVID-19 through 6 months.

Invivyd is evaluating the 4500 mg dose of VYD222 in the CANOPY clinical trial.

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 more than 9 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 in pseudovirus assays against various pre-Omicron and Omicron variants, such as JN.1, HV.1, BA.2.86, XBB.1.5.10/EG.5, and HK.3. 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.
