Lilly announces three acquisitions to build infectious disease portfolio

[26-May-2026]

Agreements with Curevo, LimmaTech Biologics and Vaccine Company address viral pathogens linked to long-term neurological and oncological risk, and bacterial pathogens that are difficult to prevent or treat

Acquisitions build on Lilly's infectious disease legacy and reinforce its commitment to prevention strategies that reduce the long-term burden of serious disease

INDIANAPOLIS, May 26, 2026 /PRNewswire/ -- Eli Lilly and Company (NYSE: LLY) today announced agreements to acquire three companies, Curevo Inc. (Curevo), LimmaTech Biologics AG (LimmaTech Biologics), and Vaccine Company, Inc. (Vaccine Company), that expand its research and development efforts into infectious disease. The transactions advance Lilly's strategy of investing in differentiated technology platforms to address significant health problems.

For 150 years, Lilly has advanced medicines to address the world's most pressing health challenges. Infectious diseases remain a major source of global morbidity, both in their acute presentation and in the downstream health consequences of primary infection.

"These acquisitions reflect a deliberate strategy to prevent disease at its source rather than treat its consequences," said Daniel M. Skovronsky, M.D., Ph.D., chief scientific and product officer, and president, Lilly Research Laboratories. "Decades of evidence now link common infections to diseases that potentially emerge years later, including neurological disease, cancer and infertility. And as antimicrobial resistance erodes our ability to treat bacterial infections, vaccines are increasingly the only path to prevention. Combining these companies' platforms and teams with Lilly's global scale positions us to change that trajectory."

Curevo's lead product candidate is amezosvatein, an adjuvanted subunit vaccine for the prevention of shingles in adults. While the current standard of care for shingles prevention is effective, tolerability challenges can limit the overall vaccination rates and contribute to second-dose hesitancy, leaving a meaningful portion of patients with reduced or no protection against shingles and its long-term consequences. Amezosvatein was engineered with a next-generation synthetic adjuvant to overcome this problem. In a Phase 2 clinical trial head-to-head against the standard of care, amezosvatein matched immune response across all primary endpoints and reduced side effects such as activity-limiting fatigue, chills, and pain at the injection site by more than half. Given growing evidence linking shingles to elevated risk of stroke, and that shingles vaccination is associated with reduced dementia risk, a meaningfully better-tolerated vaccine could expand the reach of shingles prevention and reduce these long-term risks at a population level.

Under the terms of the agreement, Lilly will acquire Curevo and Curevo shareholders could receive up to $1.5 billion in cash, inclusive of an upfront payment and subsequent payment upon achievement of a specified milestone.

LimmaTech Biologics is developing vaccines against bacterial pathogens for which rising antimicrobial resistance is steadily closing therapeutic options, including Staphylococcus aureus, Neisseria gonorrhoeae, and Chlamydia trachomatis. The company's proprietary platform is designed to generate broad, durable immune responses against complex bacterial targets by targeting the toxins and superantigens that drive disease. LimmaTech's lead program, LTB-SA7, is in Phase 1 development as a vaccine against S. aureus, the leading cause of surgical-site infection. The company's preclinical pipeline is pursuing additional bacterial pathogens, including those that drive infertility and other long-term consequences of infection that fall disproportionately on women. A vaccine-led prevention strategy could change the trajectory of diseases that are becoming increasingly difficult to treat.

Under the terms of the agreement, Lilly will acquire LimmaTech for up to $780 million in cash, inclusive of an upfront payment and additional potential payments based upon the achievement of certain clinical and regulatory milestones.

Vaccine Company is developing proprietary In Vivo Nanoparticle (IVN) technologies designed to enable the antigen display known to elicit durable immune responses associated with virus-like particle vaccines, while avoiding the manufacturing burden of traditional VLP production. The company is advancing a broad preclinical pipeline spanning multiple viral pathogens; the lead program applies this technology to Epstein-Barr Virus (EBV) with a five-antigen Phase 1-ready candidate. Given the growing evidence linking EBV to multiple sclerosis and several malignancies, a prophylactic vaccine could prevent not only acute infectious mononucleosis but also the long-term neurological and oncological consequences that may follow infection.

Under the terms of the agreement, Lilly will acquire Vaccine Company and Vaccine Company shareholders could receive up to $1.55 billion in cash, inclusive of an upfront payment and subsequent payments upon achievement of certain clinical and commercial milestones.

These transactions are subject to customary closing conditions, including expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. Lilly will determine the accounting treatment of these transactions following closing in accordance with Generally Accepted Accounting Principles (GAAP). These transactions will thereafter be reflected in Lilly's financial results and financial guidance.
