WALTHAM, Mass., May 31, 2024 (GLOBE NEWSWIRE) -- Invivyd, Inc. (Nasdaq: IVVD), a biopharmaceutical company devoted to delivering protection from serious viral infectious diseases, today announced general alignment with the U.S. Food and Drug Administration (FDA) on an expedient, repeatable immunobridging pathway to future potential emergency use authorizations (EUAs) for serial, novel monoclonal antibodies (mAbs) for the prevention and treatment of symptomatic COVID-19. Coupled with Invivyd’s proprietary mAb technology platform and engineering capabilities, this pathway provides the company with the opportunity to rapidly, efficiently, and durably deliver high value medicines that prevent and treat symptomatic COVID-19 in vulnerable populations.

This pathway provides for the establishment of a master, registrational clinical trial protocol that could obviate the need to submit a new protocol for the evaluation of each new mAb, streamlining the process required to evaluate new mAbs in compact clinical programs envisioned to include hundreds of participants (e.g., 300-600) exposed to a new mAb, with the specific number of exposures to be determined in consultation with the FDA. This compact, repeatable immunobridging pathway is similar to the approach Invivyd used to obtain an EUA for PEMGARDA™ for pre-exposure prophylaxis (PrEP) but would leverage a more efficient route to obtaining the safety and pharmacokinetics (PK) data that could support future potential EUA requests. The direct clinical cost of generating the safety and PK data contemplated in this pathway is estimated at $25-40 million.

“We are pleased to gain general alignment with the FDA on a repeatable, rapid pathway toward addressing the ongoing, critical unmet need for novel options for the prevention and treatment of symptomatic COVID-19. As the speed of SARS-CoV-2 viral evolution has become the defining feature that limits antibody development and commercialization, our work over the last two years has focused on driving novel development pathways to allow our technology to match or exceed the pace of viral evolution,” commented Marc Elia, Chairman of the Invivyd Board of Directors. “We look forward to discussing this approach with global regulators outside the U.S., as it represents a potentially transformational pathway to bring high value medicines to patients in need in a repeatable fashion, apace with rapid viral evolution.”

“Our alignment on a defined pathway to potential future EUAs represents an important step forward for unlocking this unique class of medicines that can potentially both treat and prevent COVID-19,” said Mark Wingertzahn, SVP of Clinical Development and Medical Affairs. “The central challenge for advancing this COVID-19 mAb field has been the need for rapid discovery innovation combined with a rapid, clear, and reliable pathway for establishing the clinical evidence that can bring molecules to patients in need in an efficient manner. We are looking forward to innovating within this defined pathway as we seek to improve the patient and system-friendliness of our molecules by exploring, for example, intramuscular and other presentations that may have access advantages for both PrEP and treatment of COVID-19.”

About PEMGARDA

PEMGARDA™ (pemivibart) is a half-life extended investigational monoclonal antibody (mAb). PEMGARDA was engineered from adintrevimab, Invivyd’s investigational mAb that has a robust safety data package and provided evidence of clinical efficacy in a global Phase 2/3 clinical trial for the prevention and treatment of COVID-19. PEMGARDA has demonstrated in vitro neutralizing activity in pseudotyped virus-like particle and authentic virus neutralization assays against major SARS-CoV-2 variants, including JN.1. PEMGARDA targets the SARS-CoV-2 spike protein receptor binding domain (RBD), thereby inhibiting virus attachment to the human ACE2 receptor on host cells.

PEMGARDA (pemivibart) injection (4500 mg), for intravenous use is an investigational mAb that has not been approved, but has been authorized for emergency use by the U.S. FDA under an EUA for the pre-exposure prophylaxis (prevention) of COVID-19 in adults and adolescents (12 years of age and older weighing at least 40 kg) who have moderate-to-severe immune compromise due to certain medical conditions or receipt of certain immunosuppressive medications or treatments and are unlikely to mount an adequate immune response to COVID-19 vaccination. Recipients should not be currently infected with or have had a known recent exposure to an individual infected with SARS-CoV-2. PEMGARDA is not authorized for use for treatment of COVID-19 or post-exposure prophylaxis of COVID-19. Anaphylaxis has been observed with PEMGARDA and the PEMGARDA Fact Sheet for Healthcare Providers includes a boxed warning for anaphylaxis. The most common adverse events (all grades, incidence ≥2%) observed in participants who have moderate-to-severe immune compromise treated with PEMGARDA included systemic and local infusion-related or hypersensitivity reactions, upper respiratory tract infection, viral infection, influenza-like illness, fatigue, headache, and nausea. For additional information, please see the PEMGARDA full product Fact Sheet for Healthcare Providers, including important safety information and boxed warning.

To support the EUA for PEMGARDA, an immunobridging approach was used to determine if PEMGARDA may be effective for pre-exposure prophylaxis of COVID-19. Immunobridging is based on the serum virus neutralizing titer-efficacy relationships identified with other neutralizing human mAbs against SARS-CoV-2. This includes adintrevimab, the parent mAb of pemivibart, and other mAbs that were previously authorized for EUA. There are limitations of the data supporting the benefits of PEMGARDA. Evidence of clinical efficacy for other neutralizing human mAbs against SARS-CoV-2 was based on different populations and SARS-CoV-2 variants that are no longer circulating. Additionally, the variability associated with cell-based EC50 value determinations, along with limitations related to pharmacokinetic data and efficacy estimates for the mAbs in prior clinical trials, impact the ability to precisely estimate protective titer ranges.

The emergency use of PEMGARDA is only authorized for the duration of the declaration that circumstances exist justifying the authorization of the emergency use of drugs and biological products during the COVID-19 pandemic under Section 564(b)(1) of the Federal Food, Drug, and Cosmetic Act, 21 U.S.C. § 360bbb-3(b)(1), unless the declaration is terminated or authorization revoked sooner.
