**Exhibit 99.1**![LOGO](g936404dsp12.jpg)

**Invivyd Reports Second Quarter 2025 Financial Results and Recent Business Highlights** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *PEMGARDA <sup>®</sup> (pemivibart) net product revenue of $11.8 million reported for Q2 2025, representing 413% growth year-over-year* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Invivyd's target of near-term profitability (1H 2025) was not met but remains possible with the upcoming respiratory virus season* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Announced alignment with U.S. FDA on rapid pathway to full approval (BLA) of vaccine alternative monoclonal antibody candidate VYD2311 to protect American adults and adolescents from COVID-19* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Announced attractive safety profile and pharmacokinetics data for VYD2311 from our pre-pivotal first-in-human clinical trial, including 76-day observed half-life for IM route of administration, allowing for potential long-term protection* 

WALTHAM, Mass., August 14, 2025 – Invivyd, Inc. (Nasdaq: IVVD) today announced financial results for the quarter ended June 30, 2025, and provided recent business highlights.

"We believe we are entering a remarkable period of change for the company that points toward an exciting future," said Marc Elia, Chairman of the Board at Invivyd. "Having characterized VYD2311 safety and pharmacokinetics in our Phase 1/2 trial, we are fully engaged on designing our clinical and go-to-market strategy for what we believe will be an exciting alternative to COVID-19 vaccination. As PEMGARDA<sup>®</sup> (pemivibart) moves into the fall season, we expect to move quickly to cement our position as the leading provider of monoclonal antibody technology for Americans in need of COVID-19 protection. With U.S. Food and Drug Administration (FDA) advice in hand, we look forward to the VYD2311 Phase 2/3 clinical trial design and finalization with the FDA, including anticipated alignment on a pivotal study plan for pediatrics, and advancement of other pipeline opportunities that leverage our technology, such as RSV and measles."

"While the second quarter PEMGARDA growth was modest, the base business is growing along with our internal commercial capabilities, while we are simultaneously looking toward an improved target product profile with VYD2311 to protect ordinary Americans from symptomatic COVID-19," said Bill Duke, Chief Financial Officer of Invivyd. "In addition to further protocol development to advance VYD2311, we look forward to additional upcoming anticipated milestones including identification of a potentially best-in-class RSV candidate in Q3 2025, identification of a preclinical measles candidate by the end of 2025, and advancement of our efforts to support the Long COVID community with the recently formed SPEAR Study Group."

**Recent Business Highlights** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** **Commercial Execution** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• PEMGARDA<sup>®</sup> (pemivibart) uptake continues to grow among
healthcare providers caring for immunocompromised patients, supported by Invivyd's in-house sales force and expanded field presence across key specialties, even during period of low COVID-19 transmission.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Pemivibart has been added to the National Comprehensive Cancer Network<sup>®</sup> (NCCN<sup>®</sup>) Clinical Practice Guidelines in Oncology for B-Cell Lymphomas.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** **Clinical & Regulatory Developments** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In June 2025, Invivyd announced positive full Phase 1/2 clinical data for VYD2311, a next-generation monoclonal
antibody (mAb) candidate designed to prevent and treat COVID-19, including an attractive safety profile demonstrated across all dosing cohorts and routes of administration – intravenous (IV), subcutaneous
(SC), and intramuscular (IM); all reported adverse events (AEs) were deemed unrelated or classified as mild to moderate and largely related to injection site and infusion reactions with no serious or severe AEs observed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Following a single dose, serum concentrations of VYD2311 remained high at six months with an observed half-life
of the IM dose route having the longest duration at 76.0 (CI: 68.5 – 90.7) days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Comprehensive dose modeling of VYD2311 serum virus neutralizing antibody (sVNA) titers (submitted to FDA and
recently published in medRxiv) indicates possible strong protection from symptomatic COVID-19 achievable via IM dosing on a long interval (months to quarters and beyond).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Following a Type C meeting in July 2025, Invivyd announced alignment with FDA on a rapid pathway to full approval
(BLA) of vaccine alternative monoclonal antibody VYD2311 to protect American adults and adolescents from COVID-19, subject to agreement on safety database size for Phase 2/3 clinical trial and pending full
protocol review, and announced the company's objectives for VYD2311 development.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Biologics License Application (BLA) pathway for VYD2311 to be supported by a single, Phase 2/3 randomized,
double-blind, placebo-controlled trial with a primary endpoint of reduction in symptomatic COVID-19, resembling CANOPY Cohort B.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Company's target product profile for VYD2311 is low-dose, IM,
scalable, low-cost, long-lasting, protective option for target populations, including adults and adolescents (12 years+; 40kg+) and, subject to FDA alignment, pediatrics (aged 0 to 12 years).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Company anticipates compact trial (12-week primary endpoint analysis)
evaluating prevention of COVID-19 largely among ordinary Americans, enabling rapid enrollment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Planned head-to-head safety
evaluation of VYD2311 with COVID-19 vaccine, pending regulatory alignment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** **Pipeline Expansion** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Company has initiated discovery efforts to assess pipeline expansion beyond SARS-CoV-2, including potential targets such as respiratory syncytial virus (RSV) and measles.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Company anticipates providing an update on identification of an RSV candidate in the third quarter of 2025 and an
update on identification of a preclinical measles mAb candidate in the fourth quarter of 2025.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** **Corporate and Financial Updates** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In July 2025, Invivyd and leading researchers formed SPEAR (Spike Protein Elimination and Recovery) Study Group
to assess the effects of mAb therapy for Long COVID and COVID-19 Post-Vaccination Syndrome.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In April 2025, Invivyd entered into a $30 million non-dilutive term
loan facility with Silicon Valley Bank, a division of First Citizens Bank, supporting balance sheet optionality and providing potential additional runway for commercial and pipeline execution if certain conditions and milestones are met.

**Second Quarter 2025 Financial Results:** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Revenue:** Reported Q2 2025 PEMGARDA net product revenue of $11.8 million, as compared to
$2.3 million in Q2 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Cash Position:** Cash and cash equivalents were $34.9 million as of June 30, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Research & Development (R&D) Expenses (including In-Process R&D):** R&D expenses were $9.6 million for the quarter ended June 30, 2025, compared to $30.3 million for the comparable period of 2024. This decrease is primarily
attributable to a decrease in commercial manufacturing costs of VYD2311, a decrease in clinical trial costs related to our CANOPY Phase 3 clinical trial and a decrease in personnel-related costs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Selling, General & Administrative (SG&A) Expenses:** SG&A expenses were
$16.6 million for the quarter ended June 30, 2025, compared to $21.1 million for the comparable period of 2024. This decrease is primarily attributable to a decrease in stock-based compensation expense, partially offset by increased
headcount-related costs and professional services fees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Net Loss and Net Loss per Share:** Net loss was $14.7 million for the quarter ended June 30, 2025,
compared to $47.2 million for the comparable period in 2024. Basic and diluted net loss per share was $0.12 for the quarter ended June 30, 2025, compared to $0.40 for the comparable period in 2024.

**About PEMGARDA** 

PEMGARDA<sup>®</sup> (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 global Phase 2/3 clinical trials for the prevention and treatment of COVID-19. PEMGARDA has demonstrated in vitro neutralizing activity against major SARS-CoV-2 variants, including JN.1, KP.3.1.1, XEC and LP.8.1. 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, treatment of Long COVID, or post-exposure prophylaxis of COVID-19. Pre-exposure prophylaxis with PEMGARDA is not a substitute for vaccination in individuals for whom COVID-19 vaccination is recommended. Individuals for whom COVID-19 vaccination is recommended, including individuals with moderate-to-severe immune compromise who may derive benefit from COVID-19 vaccinations, should receive COVID-19 vaccination. In individuals who have recently received a COVID-19 vaccine, PEMGARDA should be administered at least 2 weeks after vaccination.

------

Anaphylaxis has been observed with PEMGARDA and the PEMGARDA Fact Sheet for Healthcare Providers includes a boxed warning for anaphylaxis. The most common adverse reactions included systemic infusion-related reactions and hypersensitivity reactions, local infusion site reactions, and infusion site infiltration or extravasation. 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. Further, 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. Additionally, certain SARS-CoV-2 viral variants may emerge that have substantially reduced susceptibility to PEMGARDA, and PEMGARDA may not be effective at preventing COVID-19 caused by these SARS-CoV-2 viral variants.

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. PEMGARDA is authorized for use only when the combined national frequency of variants with substantially reduced susceptibility to PEMGARDA is less than or equal to 90%, based on available information including variant susceptibility to PEMGARDA and national variant frequencies.

**About CANOPY** 

The CANOPY Phase 3 clinical trial was designed to evaluate the safety and tolerability of pemivibart and to assess immunobridging from pemivibart 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). Additionally, there were pre-specified exploratory endpoints through three, six and twelve months to evaluate clinical efficacy of pemivibart compared to placebo in the prevention of RT-PCR-confirmed symptomatic COVID-19. The latest analysis from the Phase 3 CANOPY clinical trial included 365-day data. The CANOPY clinical trial enrolled participants in two cohorts: Cohort A was a single-arm, open-label trial in adults with moderate-to-severe immune compromise including complex underlying medical conditions. Cohort B was a randomized, placebo-controlled cohort that enrolled adults without moderate-to-severe immune compromise at risk of acquiring COVID-19 due to regular unmasked face-to-face interactions in indoor settings.

**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 Invivyd** 

Invivyd, Inc. (Nasdaq: IVVD) 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.

**Invivyd Aligns with U.S. FDA on Rapid Pathway to Full Approval (BLA) of Vaccine Alternative Monoclonal Antibody VYD2311 to Protect American Adults and Adolescents from COVID-19** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Alignment follows Type C meeting for VYD2311 as previously disclosed* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *BLA pathway for VYD2311 to be supported by a single, Phase 2/3 randomized, double-blind, placebo-controlled trial with a primary endpoint of reduction in symptomatic COVID-19, resembling CANOPY Cohort B* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Company's target product profile is low-dose, intramuscular, scalable, low-cost, long-lasting, protective option for target populations, including adults and adolescents (12 years+; 40kg+) and, subject to FDA alignment, pediatrics (aged 0 to 12 years)* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Anticipate compact trial (12-week primary endpoint analysis) evaluating prevention of COVID-19 largely among ordinary Americans, enabling rapid enrollment* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Planned head-to-head safety evaluation with COVID-19 vaccine, pending regulatory alignment* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Quantities of VYD2311 potential commercial launch product available* 

Waltham, Mass., August 14, 2025 – Invivyd, Inc. (Nasdaq: IVVD) today announced it has received and is aligned with advice from the U.S. Food and Drug Administration (FDA) on a compact and, therefore, rapid pathway to potential Biologics License Application (BLA) approval for Invivyd's novel monoclonal antibody (mAb) candidate VYD2311, for the prevention of COVID-19. As part of a recent Type C meeting, FDA advised that a single, Phase 2/3 randomized, double-blind, placebo-controlled trial evaluating mAb efficacy from a relatively modest number of RT-PCR -confirmed symptomatic COVID-19 disease events could support a BLA submission for VYD2311 for the prevention of COVID-19 in a broad population of Americans (12 years of age and older, weighing at least 40kg), including immunocompromised people, subject to agreement on safety database size and pending full protocol review.

"We believe monoclonal antibodies such as VYD2311 can serve as a powerful alternative to vaccines for COVID-19 prevention, and represent an important potential paradigm shift to move American medicine beyond the real and perceived limitations of COVID-19 vaccines. Amidst declining public trust in vaccines, we want to offer Americans a new, non-vaccine choice," said Marc Elia, Chairman of Invivyd's Board of Directors. "COVID-19 monoclonal antibody medicines work alongside natural human immunity without needing to activate the immune system, and, if we can make them widely available, we believe mAbs represent the natural next step beyond vaccination to keep people safe and well, if approved, in the face of pervasive COVID-19."

FDA advice and background statements to Invivyd cited observations on Invivyd's efficient execution of its Phase 3 randomized clinical trial of pemivibart for the prevention of COVID-19 (CANOPY), the antiviral durability of pemivibart, and the strong protection demonstrated by pemivibart among ordinary Americans in CANOPY Cohort B, while recognizing that Invivyd antibodies stem from a common molecular lineage. Multiple such Invivyd antibodies have undergone successful randomized, placebo-controlled clinical trials, including efficacy assessment in contemporary Americans. In agreement with FDA advice, Invivyd plans to study two doses of VYD2311 to assess any differences in resulting levels of protection or differences in safety, with a goal to unlock further choice for Americans in need of COVID-19 protection.

------

"We are grateful for the FDA's clear and constructive feedback, which provides a well-defined path forward for our COVID-19 development program. We believe the FDA's feedback underscores the shared urgency to advance innovative solutions for prevention of COVID-19," said Rachael Gerlach, Ph.D., Vice President, Regulatory Affairs at Invivyd. "Combined with Invivyd's unique discovery platform, this alignment is a critical step in bringing forward a potentially important, medically attractive and patient-friendly alternative to COVID vaccination, providing protective monoclonal antibodies, if approved, to any American who wishes protection, whether immune compromised, at high risk for severe disease, or just interested in not getting sick."

The FDA provided advice for pursuit of a traditional BLA pathway for the prevention of COVID-19 caused by SARS-CoV-2 in adults and adolescents weighing at least 40 kg, recommending a Phase 2/3 randomized, double-blind, placebo-controlled trial with a primary endpoint of RT-PCR-confirmed symptomatic COVID-19, with a timepoint for measuring the primary endpoint coinciding with the expected duration of protection, anticipated as 12 weeks (3 months), and the potential for selection of an additional, longer duration timepoint, which Invivyd anticipates as 24 weeks (6 months).

Invivyd's analysis of CANOPY clinical trial data and Cox Proportional Hazards modeling, combined with biophysical properties of VYD2311, suggest likely robust, long-term protection from symptomatic COVID-19 due to high potency and observed long half-life of ~76 days, following a relatively low dose of VYD2311 via intramuscular route of administration. Invivyd's most recent analysis aligns well with multiple similar analyses spanning the majority of SARS-CoV-2 virus variation since emerging as a global human disease in 2020, lending confidence to dose selection and anticipated clinical benefit. In addition, as COVID-19 monoclonal antibodies represent additional immune support and do not require engagement of the human immune system with associated inflammation symptoms (reactogenicity), Invivyd anticipates, pending regulatory alignment, a clinical trial cohort exploring randomized, active-controlled safety and tolerability of VYD2311 compared to vaccination.

"Our completed first-in-human study of VYD2311 demonstrated high SARS-CoV-2 antiviral titers and an attractive safety profile at very high doses, well beyond doses we contemplate going forward with in development. We look forward to opening a U.S. IND and moving as quickly as possible to finalize a pivotal clinical trial design with the FDA," said Mark Wingertzahn, Ph.D., Senior Vice President, Clinical Development at Invivyd, "If successful, we have the potential to change practice and provide consumers and central health authorities with an attractive alternative to COVID-19 vaccination. We anticipate sharing our plans as soon as possible once we finalize them with FDA."

Invivyd has quantities of VYD2311 clinical supply and potential commercial launch product available.

**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 PEMGARDA** 

PEMGARDA<sup>®</sup> (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 global Phase 2/3 clinical trials for the prevention and treatment of COVID-19. PEMGARDA has demonstrated in vitro neutralizing activity against major SARS-CoV-2 variants, including JN.1, KP.3.1.1, XEC and LP.8.1. 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, treatment of Long COVID, or post-exposure prophylaxis of COVID-19. Pre-exposure prophylaxis with PEMGARDA is not a substitute for vaccination in individuals for whom COVID-19 vaccination is recommended. Individuals for whom COVID-19 vaccination is recommended, including individuals with moderate-to-severe immune compromise who may derive benefit from COVID-19 vaccinations, should receive COVID-19 vaccination. In individuals who have recently received a COVID-19 vaccine, PEMGARDA should be administered at least 2 weeks after vaccination.

Anaphylaxis has been observed with PEMGARDA and the PEMGARDA Fact Sheet for Healthcare Providers includes a boxed warning for anaphylaxis. The most common adverse reactions included systemic infusion-related reactions and hypersensitivity reactions, local infusion site reactions, and infusion site infiltration or extravasation. 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. Further, 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. Additionally, certain SARS-CoV-2 viral variants may emerge that have substantially reduced susceptibility to PEMGARDA, and PEMGARDA may not be effective at preventing COVID-19 caused by these SARS-CoV-2 viral variants.

------

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. PEMGARDA is authorized for use only when the combined national frequency of variants with substantially reduced susceptibility to PEMGARDA is less than or equal to 90%, based on available information including variant susceptibility to PEMGARDA and national variant frequencies.

PEMGARDA AUTHORIZED VIA EUA FOR THE PREVENTION OF COVID-19 FOR CERTAIN IMMUNOCOMPROMISED PERSONS PEMGARDA has not been approved but has been authorized for emergency use by the FDA under an emergency use authorization (EUA), for pre-exposure prophylaxis of COVID-19 in certain adults and adolescents (12 years of age and older weighing at least 40 kg) with moderate-to-severe immune compromise. Pre-exposure prophylaxis with PEMGARDA is not a substitute for vaccination in individuals for whom COVID-19 vaccination is recommended. Individuals for whom COVID-19 vaccination is recommended, including individuals with moderate-to-severe immune compromise who may derive benefit from COVID-19 vaccinations, should receive COVID-19 vaccination. In individuals who have recently received a COVID-19 vaccine, PEMGARDA should be administered at least 2 weeks after vaccination. 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 is revoked sooner. PEMGARDA is authorized for use only when the combined national frequency of variants with substantially reduced susceptibility to PEMGARDA is less than or equal to 90%, based on available information including variant susceptibility to PEMGARDA and national variant frequencies. For additional information, please see the PEMGARDA full product Fact Sheet for Healthcare Providers, including Important Safety Information and Boxed Warning.
