WALTHAM, Mass., May 9, 2024 (GLOBE NEWSWIRE) — Invivyd, Inc. (Nasdaq: IVVD), a biopharmaceutical company devoted to delivering protection from serious viral infectious diseases, today announced financial results for the quarter ended March 31, 2024, and recent business highlights.

“The recent months have been incredibly productive for Invivyd. Moving into the commercial phase is a critical step for the company and we are executing on the PEMGARDA launch with maximum focus across the company,” said Marc Elia, Chairman of the Invivyd Board of Directors. “In addition, we look forward to sharing on today’s quarterly update call more of the scientific underpinnings of our plans going forward, including detail on the innovative engine we believe can deliver meaningful product-level advancements with associated medical and economic value creation.”

Recent Business Highlights

 

•

Launched PEMGARDA, the company’s first monoclonal antibody (mAb) in a planned series of innovative antibodies, in the U.S.: On March 22, 2024, PEMGARDA (pemivibart) received emergency use authorization (EUA) from the U.S. Food and Drug Administration (FDA) for the pre-exposure prophylaxis (PrEP) of COVID-19 in certain adults and adolescents with moderate-to-severe immune compromise. At the beginning

of April, Invivyd announced that PEMGARDA is available for purchase in the U.S. through a network of authorized specialty distributors. At the end of April, Invivyd’s market access and sales, as well as medical affairs, teams were fully operational across the U.S. The company will begin reporting PEMGARDA net product revenue with its second quarter 2024 financial results.

 

•

Received product-specific reimbursement codes covering PEMGARDA from the U.S. Centers for Medicare & Medicaid (CMS): In April 2024, Invivyd announced that CMS has granted a Healthcare Common Procedure Coding System (HCPCS) Q code (Q0224) covering product reimbursement and a product specific M code (M0224) covering the administration of PEMGARDA. The company estimates that CMS provides coverage for nearly half of the moderately to severely immunocompromised people at highest risk for severe COVID-19 that the company is initially targeting.

 

•

Reported interim exploratory COVID-19 clinical event data from CANOPY Phase 3 clinical trial of VYD222: In March 2024, Invivyd announced interim exploratory data from the ongoing CANOPY Phase 3 clinical trial that reflect and add further to the initial potential signal of clinical protection from symptomatic COVID-19 shared in December 2023. While not part of the primary immunobridging endpoint of the CANOPY clinical trial, the interim exploratory data may be hypothesis generating for future discovery and development work.

Recent Pipeline Highlights

 

•

Announced plans to pursue rapid immunobridging pathway to potential EUA for COVID-19 treatment in certain immunocompromised people, based on U.S. FDA feedback: In May 2024, Invivyd announced that it anticipates imminently submitting an EUA application to the FDA for pemivibart for the treatment of mild to moderate symptomatic COVID-19 in certain immunocompromised people utilizing a rapid immunobridging pathway. This immunobridging pathway leverages a similar approach Invivyd used to achieve its current EUA for PEMGARDA for COVID-19 PrEP in certain immunocompromised people and was aligned in principle with the FDA.

 

•

Continued to advance VYD2311, the company’s next anticipated mAb candidate: In March 2024, Invivyd announced that it expects that VYD2311 will be the next anti-SARS-CoV-2 mAb candidate that it advances into clinical development. VYD2311 is optimized for neutralization potency against recent SARS-CoV-2 lineages such as BA.2.86 and JN.1. The design of VYD2311 leverages Invivyd’s state-of-the-art technologies for variant surveillance, predictive modeling, and antibody engineering.

First Quarter 2024 Financial Results:

 

•

Cash Position: Cash and cash equivalents were $189.4 million as of March 31, 2024.

---

•

Projected 2024 Year-End Cash Position: Based on current operating plans, Invivyd expects to end 2024 with at least $75 million in cash and cash equivalents, based on anticipated 2024 net product revenue of $150 million to $200 million and recent resource realignment. Invivyd is maintaining its existing guidance, although the previously issued guidance was based on PEMGARDA being authorized for PrEP of COVID-19 in certain immunocompromised people and did not contemplate any potential sales for COVID-19 treatment, if authorized, or inventory build that may be required to deliver medicine timely to patients in need.

 

•

Research & Development (R&D) Expenses (including In-Process R&D): R&D expenses were $31.2 million for the quarter ended March 31, 2024, compared to $28.0 million for the comparable period of 2023. This increase is primarily attributable to an increase in commercial manufacturing costs of PEMGARDA and an increase in clinical trial costs related to the ongoing monitoring of our CANOPY Phase 3 clinical trial.

 

•

Selling, General & Administrative (SG&A) Expenses: SG&A expenses were $14.9 million for the quarter ended March 31, 2024, compared to $11.0 million for the comparable period of 2023. This increase is primarily attributable to an increase in personnel-related costs and commercial costs driven by the preparation for launch of PEMGARDA.

 

•

Net Loss and Net Loss per Share: Net loss was $43.5 million for the quarter ended March 31, 2024, compared to $35.3 million for the comparable period in 2023. Basic and diluted net loss per share was $0.38 for the quarter ended March 31, 2024, compared to $0.32 for the comparable period in 2023.

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.

EPITOPIC ANALYSIS IS BUILT FROM INDIVIDUAL RESIDUE ANALYSIS SARS-CoV-2 spike protein evolution is Individual residue analysis yields two observations tracked at the residue (amino acid) level 1. Observed mutational potential at individual amino acid positions or for a complete epitope are increasingly informative of future divergence 2. To date, the VYD222 epitope (area of RBD outlined in blue below) has been stable Lower polymorphic plasticity Higher polymorphic plasticity Each graph represents the frequency of different substitutions observed at one specific amino acid position in the receptor binding domain (RBD) of the spike Aug Sep Oct Nov Dec Jan Feb Mar 2023 | 2024 Note: Epitope is defined as all residues within 5 angstroms of VYD222 binding interface determined via co-crystal analysis. 16
