WALTHAM, Mass., March 28, 2024 (GLOBE NEWSWIRE) -- Invivyd, Inc. (Nasdaq: IVVD), a biopharmaceutical company on a mission to protect the vulnerable from serious viral infectious diseases, today announced financial results for the full year ended December 31, 2023 and recent business highlights.

“We made remarkable progress throughout 2023 and in recent months. Roughly one year ago we were initiating the Phase 1 clinical trial of VYD222, and today we are incredibly proud to have received emergency use authorization (EUA) of PEMGARDA for PrEP of COVID-19 in certain adults and adolescents (aged 12 or older weighing at least 40kg) in the U.S. with moderate-to-severe immune compromise who are unlikely to mount an adequate response to COVID-19 vaccination,” said Dave Hering, Chief Executive Officer of Invivyd. “PEMGARDA is the first PrEP mAb to receive an EUA using a rapid immunobridging trial design leveraging a biomarker as a surrogate of clinical efficacy and the first authorized mAb from our novel platform approach designed to rapidly and serially engineer durable mAbs targeting conserved viral epitopes. This exciting milestone is a testament to our team’s incredible dedication, skill, and ability to execute to plan.”

Mr. Hering continued, “With PEMGARDA now authorized and anticipated to be available for order in the U.S. imminently, we are laser-focused on executing our commercial launch plan and look forward to providing insights on key launch metrics as time progresses. With a relatively compact field sales organization, we believe that we can efficiently reach key healthcare practitioners and institutions who care for the highest risk moderately to severely immunocompromised adults and adolescents, with the opportunity to potentially expand our efforts and footprint over time within our authorized population.”

Recent Program Highlights

• PEMGARDA received EUA from U.S. FDA: On March 22, 2024, PEMGARDA (pemivibart) received EUA from the U.S. Food and Drug Administration (FDA) 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 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. The PEMGARDA EUA is based on the totality of scientific evidence available, including data from the company’s CANOPY clinical trial based on an immunobridging approach. The company expects to have PEMGARDA available for order in the U.S. imminently and is preparing for the full commercial launch of PEMGARDA, with the deployment of the contracted field sales force expected in the coming weeks.
• Leveraged INVYMAB™ platform approach to design VYD2311, the company’s next anticipated anti-SARS-CoV-2 mAb in a planned series of candidates: In January 2024, Invivyd nominated VYD2311, a mAb optimized for neutralization potency against recent SARS-CoV-2 lineages such as BA.2.86 and JN.1, as a drug candidate. The company expects that VYD2311 will be the next candidate that it advances into clinical development. The company continues to engage with the FDA with the aim of establishing a streamlined development pathway that would allow the company to most efficiently leverage its INVYMAB platform approach to serially generate new or modified mAbs to keep pace with SARS-CoV-2 viral evolution.

Year End 2023 Financial Results

• Cash Position: Cash and cash equivalents were $200.6 million as of December 31, 2023.
• Cash Runway: Based on current operating plans and excluding anticipated cash collections from PEMGARDA sales, Invivyd expects its existing total cash and cash equivalents will enable the company to fund its operating expenses and capital expenditure requirements into the fourth quarter of 2024.
• Research & Development (R&D) Expenses (including In-Process Research & Development): R&D expenses were $163.6 million for the year ended December 31, 2023, compared to $183.6 million for year ended December 31, 2022. This decrease is primarily attributable to a decrease in personnel-related costs in 2023 and to higher clinical trial costs in 2022 due to ongoing adintrevimab clinical trials, with no comparable costs during the same period in 2023 due to the wind-down of adintrevimab clinical trials, partially offset by an increase in commercial manufacturing costs of PEMGARDA and ongoing clinical trial costs associated with our CANOPY clinical trial in 2023.
• Selling, General & Administrative (SG&A) Expenses: SG&A expenses were $49.1 million for the year ended December 31, 2023, compared to $47.0 million for the year ended December 31, 2022. This increase is primarily attributable to an increase in personnel-related costs and commercial costs, partially offset by a decrease in legal and corporate governance costs.
• Net Loss and Net Loss Share: Net loss was $198.6 million for the year ended December 31, 2023, compared to $241.3 million for the year ended December 31, 2022. Basic and diluted net loss per share was $1.81 for the year ended December 31, 2023, compared to $2.23 for the year ended December 31, 2022.
  

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 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, the dominant variant in the U.S. currently according to estimates from the Centers for Disease Control and Prevention. 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.

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.

IMPORTANT SAFETY INFORMATION

WARNING: ANAPHYLAXIS

• Anaphylaxis has been observed with PEMGARDA in 0.6% (4/623) of participants in a clinical trial.
• Anaphylaxis was reported during the first and second infusion of PEMGARDA.
• Anaphylaxis can be life-threatening.
• Prior to administering PEMGARDA, consider the potential benefit of COVID-19 prevention along with the risk of anaphylaxis.
• Administer PEMGARDA only in settings in which healthcare providers have immediate access to medications to treat anaphylaxis and the ability to activate the emergency medical system (EMS), as necessary.
• Clinically monitor individuals during the infusion and for at least two hours after completion of the infusion.
• Discontinue PEMGARDA immediately if signs or symptoms of anaphylaxis or any severe systemic reaction are observed and initiate appropriate medications and/or supportive therapy.
  

CONTRAINDICATIONS

PEMGARDA is contraindicated in individuals with previous severe hypersensitivity reactions, including anaphylaxis, to any component of PEMGARDA.

WARNINGS AND PRECAUTIONS

Hypersensitivity Including Anaphylaxis and Infusion-Related Reactions
Serious hypersensitivity reactions, including anaphylaxis, have been observed with PEMGARDA. If signs and symptoms of a clinically significant hypersensitivity reaction or anaphylaxis occur, immediately discontinue administration, and initiate appropriate medications and/or supportive therapy. Clinically monitor individuals during the 60-minute infusion and for at least two hours after completion of the infusion.

Risk of Cross-Hypersensitivity With COVID-19 Vaccines
PEMGARDA contains polysorbate 80, which is in some COVID-19 vaccines and is structurally similar to polyethylene glycol (PEG), an ingredient in other COVID-19 vaccines. For individuals with a history of severe hypersensitivity reaction to a COVID-19 vaccine, consider consultation with an allergist-immunologist prior to PEMGARDA administration.

Risk for COVID-19 Due to SARS-CoV-2 Viral Variants Not Neutralized by PEMGARDA
Certain SARS-CoV-2 viral variants may emerge that are not neutralized by monoclonal antibodies such as PEMGARDA. PEMGARDA may not be effective at preventing COVID-19 caused by these SARS-CoV-2 viral variants. Inform individuals of the increased risk, compared to other variants, for COVID-19 due to emergent SARS-CoV-2 viral variants not neutralized by PEMGARDA. If signs or symptoms of COVID-19 occur, advise individuals to test for COVID-19 and seek medical attention, including starting treatment for COVID-19 as appropriate.

ADVERSE REACTIONS
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.

USE IN SPECIFIC POPULATIONS

Pregnancy
There are insufficient data to evaluate a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. PEMGARDA should only be used during pregnancy if the potential benefit outweighs the potential risk for the mother and the fetus.

Lactation
There are no available data on the presence of PEMGARDA in human or animal milk, the effects on the breastfed infant, or the effects on milk production. Maternal IgG is known to be present in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for PEMGARDA and any potential adverse effects on the breastfed infant from PEMGARDA.

Pediatric Use
PEMGARDA is not authorized for use in pediatrics less than 12 years of age or weighing less than 40 kg. The safety and effectiveness of PEMGARDA has not been established in pediatrics.

EMERGENCY USE AUTHORIZATION (EUA) FOR PEMGARDA
