Invivyd Stock Price, News & Analysis
Company Description
Invivyd, Inc. (Nasdaq: IVVD) is a biopharmaceutical company focused on delivering protection from serious viral infectious diseases, beginning with SARS-CoV-2. According to company disclosures, Invivyd deploys a proprietary integrated technology platform designed to assess, monitor, develop, and adapt to create antibodies targeting high-value infectious disease threats. The company is classified under biological product (except diagnostic) manufacturing within the broader manufacturing sector.
Invivyd’s work centers on monoclonal antibody (mAb) therapies intended to prevent or treat viral infections. The company reports that in March 2024 it received emergency use authorization (EUA) from the U.S. Food and Drug Administration (FDA) for a monoclonal antibody in its pipeline of antibody candidates. This EUA supports pre-exposure prophylaxis of symptomatic COVID-19 in certain immunocompromised patients, reflecting Invivyd’s focus on populations with limited benefit from conventional vaccination strategies.
Core programs and products
Invivyd highlights several key antibody programs in its public communications:
- PEMGARDA (pemivibart): An investigational, half-life extended monoclonal antibody authorized under EUA in the U.S. for pre-exposure prophylaxis of COVID-19 in adults and adolescents with moderate-to-severe immune compromise who are unlikely to mount an adequate response to vaccination. PEMGARDA targets the SARS-CoV-2 spike protein receptor binding domain (RBD) to inhibit virus attachment to the human ACE2 receptor. Company materials describe in vitro neutralizing activity against multiple SARS-CoV-2 variants and note that PEMGARDA is not authorized for treatment of COVID-19, Long COVID, or post-exposure prophylaxis.
- VYD2311: A novel monoclonal antibody candidate being developed for COVID-19 as a vaccine-alternative option. Invivyd states that VYD2311 was engineered using its proprietary integrated technology platform and is optimized to neutralize contemporary SARS-CoV-2 lineages. The pharmacokinetic profile and antiviral potency are described as supporting intramuscular administration with the goal of maintaining clinically meaningful neutralizing titers. VYD2311 leverages the same antibody backbone as pemivibart and adintrevimab, which have generated safety and efficacy data in prior clinical trials.
- VBY329: A monoclonal antibody candidate selected for preclinical development to prevent respiratory syncytial virus (RSV) infections in neonates, infants, and children. According to Invivyd, VBY329 was generated using the company’s antibody discovery technology and is being advanced toward investigational new drug (IND) readiness for pediatric RSV prophylaxis.
- Measles mAb discovery: Invivyd reports discovery efforts aimed at a preclinical monoclonal antibody candidate for the treatment and prevention of measles, as part of a broader strategy to expand beyond SARS-CoV-2 and RSV.
Clinical development and regulatory strategy
Invivyd describes a structured clinical and regulatory program around its COVID-19 antibodies. For VYD2311, the company has outlined the REVOLUTION development program, which includes the DECLARATION and LIBERTY clinical trials. DECLARATION is a Phase 3, randomized, triple-blind, placebo-controlled pivotal trial designed to evaluate the safety and efficacy of VYD2311 in preventing symptomatic COVID-19 in adults and adolescents, including individuals with and without risk factors for severe disease. Participants receive either single or monthly intramuscular doses of VYD2311 versus placebo, with the primary endpoint focused on reduction of PCR-confirmed symptomatic COVID-19.
Company announcements state that the U.S. FDA has granted Fast Track designation for VYD2311 for the prevention of COVID in individuals with underlying risk factors for severe disease. Fast Track status is described as a regulatory mechanism that can facilitate expedited development and review for therapies addressing serious conditions and unmet medical needs, potentially enabling rolling Biologics License Application (BLA) submissions and priority review if criteria are met.
PEMGARDA’s EUA is supported by an immunobridging approach that relates neutralizing antibody titers to efficacy signals from other human monoclonal antibodies against SARS-CoV-2, including adintrevimab and previously authorized mAbs. Invivyd also conducted the CANOPY Phase 3 trial to evaluate pemivibart safety, tolerability, and immunobridging to historical data, with exploratory clinical efficacy endpoints for prevention of symptomatic COVID-19.
Technology platform and pipeline expansion
Across its disclosures, Invivyd emphasizes a proprietary integrated technology platform used to discover and optimize antibody candidates. The platform is described as enabling serial molecular evolution to generate antibodies with properties tailored to neutralize contemporary virus lineages and to address viral evolution. This approach underpins the design of VYD2311, VBY329, and additional discovery programs.
In RSV, Invivyd reports that VBY329 was selected based on in vitro antiviral potency and resistance profiles compared with existing standard-of-care medicines. Company communications describe half-life extension technology and biophysical properties intended to support extended protection windows. Beyond RSV, Invivyd notes ongoing discovery efforts for ultra-long half-life RSV antibodies and for antibodies targeting measles and other infectious diseases, particularly for vulnerable populations.
Commercial and financial context
Invivyd reports that PEMGARDA generates net product revenue from pre-exposure prophylaxis of COVID-19 in eligible immunocompromised patients. The company has disclosed growth in PEMGARDA net product revenue over successive quarters and indicates that uptake is supported by an in-house sales force and field presence among healthcare providers caring for immunocompromised populations.
The company has also undertaken multiple public offerings of common stock and pre-funded warrants, as detailed in its Form 8-K filings. Proceeds are described as supporting commercial preparedness for a potential VYD2311 launch, advancement of the VYD2311 clinical program, continued research and development for RSV and measles programs, and general corporate purposes. Invivyd also references the SPEAR (Spike Protein Elimination and Recovery) Study Group, formed with researchers to assess the effects of monoclonal antibody therapy for Long COVID and COVID-19 post-vaccination syndrome.
Exchange listing and corporate status
Invivyd’s common stock, with par value $0.0001 per share, is listed on The Nasdaq Stock Market LLC under the symbol IVVD, as confirmed in multiple Form 8-K filings. The company is incorporated in Delaware. Nasdaq correspondence disclosed in SEC filings indicates that Invivyd previously received a notice regarding the minimum bid price requirement and later regained compliance after its stock met the required bid price threshold for the specified period. There is no indication in the provided filings of delisting, deregistration, or completed merger activity.
Business model overview
Based on its public statements, Invivyd’s business model centers on the discovery, development, and commercialization of monoclonal antibody therapies for serious viral infectious diseases. Revenue is currently associated with PEMGARDA under EUA, while VYD2311, VBY329, and measles-focused candidates remain in clinical or preclinical stages. The company allocates capital raised through equity offerings to clinical development, regulatory activities, commercial readiness, and expansion of its antibody pipeline.
