New York & Saint-Herblain (France), February 17, 2023 – Pfizer Inc. (NYSE: PFE) and Valneva SE (Nasdaq: VALN; Euronext Paris: VLA) today announce that Pfizer, as the study sponsor, has decided to discontinue a significant percentage of participants in the U.S. who had been enrolled in the Vaccine Against Lyme for Outdoor Recreationists (VALOR) (NCT05477524) Phase 3 clinical study. The study is investigating the efficacy, safety and immunogenicity of an investigational Lyme disease vaccine candidate, VLA15. These study participants, representing approximately half of the total recruited participants in the trial, are being discontinued following violations of Good Clinical Practice (GCP) at certain clinical trial sites run by a third-party clinical trial site operator. The discontinuation of these participants was not due to any safety concerns with the investigational vaccine and was not prompted by a participant-reported adverse event.
GCP is the international ethical and scientific quality standard for clinical trials that all clinical researchers need to follow. These standards are designed to put participants’ interests first and ensure high scientific integrity. Once Pfizer learned of potential violations of GCP, it conducted a thorough review of the operations and data collection at the clinical trial sites run by the third party and followed standard operating safeguards to determine the correct course of action.
The clinical trial remains ongoing with other sites not operated by the third party, and Pfizer continues to enroll new participants at those sites. The companies intend to work with regulatory authorities, and as previously announced,1,2 aim for Pfizer to potentially submit a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) and Marketing Authorisation Application (MAA) to the European Medicines Agency (EMA) in 2025, pending successful completion of the Phase 3 studies and subject to the agreement of these regulatory agencies to proposed modifications of the clinical trial plan.
Participants are being notified and Pfizer has also notified the FDA, other regulatory agencies and the independent Institutional Review Board for this study.
Integrity of data collected in clinical trials is critical to provide evidence and confidence in a potential vaccine or medicine’s safety and efficacy. Pfizer and Valneva are committed to collecting robust data needed for potential regulatory submission of VLA15. While VLA15 is still under investigation, to date the companies have been encouraged by the data from the Phase 2 clinical studies, which demonstrated strong immunogenicity and acceptable safety and tolerability profiles.2-4
VLA15 is the only Lyme disease vaccine candidate currently in clinical development. This investigational multivalent protein subunit vaccine uses an established mechanism of action for a Lyme disease vaccine that targets the outer surface protein A (OspA) of Borrelia burgdorferi, the bacteria that cause Lyme disease. OspA is a surface protein expressed by the bacteria when present in a tick. Blocking OspA inhibits the bacterium’s ability to leave the tick and infect humans. The vaccine covers the six most common OspA serotypes expressed by the Borrelia burgdorferi sensu lato species that are prevalent in North America and Europe. VLA15 has demonstrated a strong immune response and satisfactory safety profile in pre-clinical and clinical studies so far. Valneva and Pfizer entered into a collaboration agreement in April 2020 to co-develop VLA15, with updates to the terms within this agreement made in June 2022.5,6 The program was granted Fast Track designation by the U.S. FDA in July 2017.7
About Lyme Disease
Lyme disease is a systemic infection caused by Borrelia burgdorferi bacteria transmitted to humans by infected Ixodes ticks.8 It is considered the most common vector-borne illness in the Northern Hemisphere.9 While the true incidence of Lyme disease is unknown, it is estimated to annually affect approximately 476,000 people in the United States and 130,000 people in Europe.10,11 Early symptoms of Lyme disease (such as a gradually expanding erythematous rash called Erythema migrans or more nonspecific symptoms like fatigue, fever, headache, mild stiff neck, arthralgia or myalgia) are often overlooked or misinterpreted. Left untreated, the disease can disseminate and cause more serious complications affecting the joints (arthritis), the heart (carditis) or the nervous system.12 The medical need for vaccination against Lyme disease is steadily increasing as the geographic footprint of the disease widens.10
