- The Phase 2 study will include both adult and pediatric subjects with an aim to support acceleration of the vaccine candidate’s pediatric program
- VLA15 will be tested at two different schedules (Month 0-2-6 or Month 0-6) receiving the selected dose of 180µg
- VLA15 is the only Lyme disease vaccine candidate in active clinical development
Saint-Herblain (France) and New York, NY, March 8, 2021 – Valneva SE (“Valneva”), a specialty vaccine company focused on prevention of diseases with major unmet needs, and Pfizer Inc. (NYSE: PFE) today announced initiation of study VLA15-221. The VLA15-221 study builds on previous positive Phase 2 studies, incorporates new dose regimens and is anticipated to be the final Phase 2 study readout before a decision to progress into pivotal Phase 3 studies.
As announced in December 2020, VLA15-221 is a randomized, observer-blind, placebo-controlled Phase 2 study. It will be the first VLA15 study to include a pediatric population (aged 5-17 years). Overall, the study will enroll approximately 600 healthy participants (aged 5-65 years) who will receive VLA15 or placebo. It will compare the three-dose vaccination schedule (Month 0-2-6) with a two-dose schedule (Month 0-6).
“We are excited to be part of the Lyme disease vaccine development program with Valneva. We hope this Phase 2 trial, with a simplified schedule, will provide evidence that the investigational vaccine can be used in populations that are at risk of contracting Lyme disease, potentially including children age five years and older,” said Kathrin Jansen, Senior Vice President and Head of Pfizer Vaccine Research and Development.
Juan Carlos Jaramillo, Chief Medical Officer von Valneva commented, “This trial initiation marks an important step in the development of VLA15 toward a potential licensure. Including a pediatric population in Phase 2 means we could, if successful, add this population to the Phase 3 research program, to potentially offer a vaccine for Lyme disease that may help prevent disease in both adults and children, if approved. We are pleased that, together with our partner Pfizer, we have decided to pursue this development while preparing for a potential Phase 3 start.”
Valneva und Pfizer schlossen im April 2020 eine Kooperationsvereinbarung zur gemeinsamen Entwicklung von VLA15 . Under the terms of the agreement, first subject, first dose in this study will trigger a milestone payment of $10 million from Pfizer to Valneva.
About VLA 15
VLA15 is the only active Lyme disease vaccine candidate in clinical development today, and covers six serotypes that are prevalent in North America and Europe. This investigational multivalent protein subunit vaccine targets the outer surface protein A (OspA) of Borrelia, an established mechanism of action for a Lyme disease vaccine. OspA is one of the most dominant surface proteins expressed by the bacteria when present in a tick. VLA15 has demonstrated strong immunogenicity and safety data in pre-clinical and clinical studies so far. The program was granted Fast Track designation by the U.S. Food and Drug Administration (FDA) in July 2017.
Valneva and Pfizer announced a collaboration for VLA15’s development and commercialization at the end of April 2020. The two companies are working closely together on the next development steps.
Über die klinische Studie VLA15-221
VLA15-221 is a randomized, observer-blind, placebo-controlled Phase 2 study. It is the first clinical study with VLA15 that enrolls a pediatric population aged 5 years and older.
A total of approximately 600 participants will receive VLA15 at two different immunization schedules (Month 0-2-6 or Month 0-6, 200 volunteers each) or placebo (Month 0-2-6, 200 volunteers). Vaccinees will receive VLA15 at a dose of 180µg, which was selected based on data generated in the two previous Phase 2 studies. The main safety and immunogenicity readout (Primary Endpoint analysis) will be at Month 7, where peak antibody titers are expected. A subset of participants will receive a booster dose of VLA15 or placebo at Month 18 (Booster Phase) and will be followed up for further three years to monitor antibody persistence.
VLA15 will be tested as an alum-adjuvanted formulation and administered intramuscularly. The study will be conducted at sites which are located in areas where Lyme disease is endemic and will enroll volunteers with a cleared past infection with Borrelia burgdorferi , the bacteria that cause Lyme disease, as well as B. burgdorferi Infektion aufgenommen.
Über Lyme Borreliose
Die Lyme-Borreliose ist eine systemische Infektion, die durch das Bakterium Borrelia bacteria burgdorferi sensu lato transmitted to humans by infected Ixodes -Zecken auf den Menschen übertragen wird. It is considered the most common vector borne illness in the Northern Hemisphere. According to the U.S. Centers for Disease Control and Prevention (CDC), approximately 476,000 Americans are diagnosed and treated for Lyme disease each year with at least a further 200,000 cases in Europe. betroffen sind. Frühe Symptome der Lyme-Borreliose (wie ein sich allmählich ausbreitender erythematöser Ausschlag, Erythema migrans or more unspecific 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. The medical need for vaccination against Lyme disease is steadily increasing as the disease footprint widens.

Über Valneva SE
Valneva is a specialty vaccine company focused on the development and commercialization of prophylactic vaccines for infectious diseases with significant unmet medical need. We take a highly specialized and targeted approach to vaccine development, beginning with the identification of deadly and debilitating infectious diseases that lack a prophylactic vaccine solution and for which there are limited therapeutic treatment options. We then apply our deep understanding of vaccine science, including our expertise across multiple vaccine modalities, as well as our established vaccine development capabilities, to develop prophylactic vaccines to address these diseases. We have leveraged our expertise and capabilities both to successfully commercialize two vaccines and to rapidly advance a broad range of vaccine candidates into and through the clinic, including candidates against Lyme disease, the chikungunya virus and COVID-19.
