(NASDAQ:<a class="ticker" href="https://www.benzinga.com/quote/IVVD">IVVD</a>) today announced enrollment of participants in its Phase 3 LIBERTY clinical trial is complete. The trial is comparing the safety and tolerability of the company's investigational COVID-19 monoclonal antibody VYD2311 with an mRNA COVID-19 vaccine. The trial is also evaluating the safety and immune response when both are given together. VYD2311 is being developed as an alternative to vaccines for preventing COVID-19. The LIBERTY study is a randomized, double-blind trial involving healthy adults. A primary endpoint of the trial is to assess the side effects and tolerability of COVID antibody versus vaccine through Day six, for a total of seven days. Invivyd expects to report initial results from the study in the third quarter of 2026. These results may be released alongside data from the company's pivotal DECLARATION clinical trial. "We are pleased that enrollment in the LIBERTY trial moved very quickly," said Marc Elia, Chairman of Invivyd's Board of Directors. "We believe this reflects strong interest in monoclonal antibodies as a way to protect people from COVID. We now look forward to executing this study, collecting data, and continuing to engage with the FDA as we seek to make VYD2311 available, if approved, to those Americans who can benefit from it as soon as possible." Dr. Michael Mina, Chief Medical Officer of Invivyd, continued, "It is rare to get a chance to conduct such a meaningful clinical comparison between two different tools for preventing disease: vaccine and monoclonal antibody. Recent studies have shown that many individuals receiving COVID-19 vaccines experience systemic side effects for an average of 3 days owing to the strong and necessary inflammatory response elicited by existing COVID-19 vaccines. Concerns about these effects have contributed to lower vaccine booster uptake, and, as a result, we at Invivyd are focused on advancing an option that may provide an important effective alternative to prevent COVID-19. If VYD2311 demonstrates an improved side effect profile and tolerability advantage over mRNA COVID vaccination, it would support the potential for VYD2311 to substantially improve public health and offer needed optionality for millions of Americans, if approved." LIBERTY is part of Invivyd's broader REVOLUTION clinical program, which is designed to establish VYD2311 as the preferred option for protection from COVID over mRNA-based vaccination, if approved. About VYD2311 VYD2311 is a novel monoclonal antibody (mAb) candidate being developed for COVID-19 to continue to address the urgent need for new prophylactic and therapeutic options. The pharmacokinetic profile and antiviral potency of VYD2311 may offer the ability to deliver clinically meaningful titer levels through more patient-friendly means such as an intramuscular route of administration. VYD2311 was engineered using Invivyd's proprietary integrated technology platform and is the product of serial molecular evolution designed to generate an antibody optimized for neutralizing contemporary virus lineages. VYD2311 leverages the same antibody backbone as pemivibart, Invivyd's investigational mAb granted emergency use authorization in the U.S. for the pre-exposure prophylaxis (PrEP) of symptomatic COVID-19 in certain immunocompromised patients, and 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 the prevention and treatment of COVID-19. About LIBERTY LIBERTY is a Phase 3, randomized, double-blind study to evaluate the safety, serum virus neutralizing antibody responses, and pharmacokinetics of VYD2311, an mRNA COVID vaccine, and co-administered VYD2311 with an mRNA COVID vaccine. Total enrollment of the trial is approximately 210 participants. About DECLARATION DECLARATION is a Phase 3, randomized, triple-blind, placebo-controlled trial to evaluate VYD2311 efficacy and safety in prevention of symptomatic COVID in a broad population of participants including adults and adolescents both with and without risk factors for progression to severe COVID-19 at three months. Participants will receive either a single dose or monthly doses of VYD2311, each administered via intramuscular (IM) injection, compared to placebo. Total enrollment of the trial is approximately 2,400 participants. About Invivyd  Invivyd, Inc. (NASDAQ:<a class="ticker" href="https://www.benzinga.com/quote/IVVD">IVVD</a>) is a biopharmaceutical company devoted to delivering protection from serious viral infectious diseases, beginning with SARS-CoV-2. Invivyd deploys a proprietary integrated technology platform unique in the industry designed to assess, monitor, develop, and adapt to create best in class antibodies. In March 2024, Invivyd received emergency use authorization (EUA) from the U.S. FDA for a monoclonal antibody (mAb) in its pipeline of innovative antibody candidates.
