• Dose selection complete for planned Phase 3 trial, expected to be initiated in 3Q2022
  • Sub-analysis compared the immunogenicity of VLA15 in adults 18-65 years of age after administration of two or three primary series doses
  • Stronger immune response observed in adult participants who received three priming doses vs. two priming doses; pediatric study ongoing with initial data expected in 1H2022
  • Three-dose priming schedule selected for use in adults moving forward

Saint-Herblain (Frankreich) und New York, February 4, 2022Valneva SE (Nasdaq: VALN; Euronext Paris: VLA), ein spezialisiertes Impfstoffunternehmen, und Pfizer Inc. (NYSE: PFE) today reported further positive Phase 2 data for their Lyme disease vaccine candidate, VLA15. Based on these new results, Valneva and Pfizer plan to proceed with a three-dose primary series vaccination schedule in a planned Phase 3 clinical trial. The trial will evaluate VLA15 in adults and pediatric subjects 5 years of age and above and is expected to be initiated in 2022, subject to regulatory approval.

The Phase 2 trial, VLA15-221, compared the immunogenicity of VLA15 after administration of two (at months 0 and 6) or three (at months 0, 2 and 6) primary series doses in groups aged 5-11, 12-17 and 18-65 years. In the sub-analysis of adult participants (18-65 years old) who received VLA15 in either the two-dose schedule (N=90) or the three-dose schedule (N=97), performed one month after the last vaccination dose, VLA15 was found to be immunogenic with both vaccination schedules tested. These data are consistent with the strong immunogenicity profile observed for this age group in previous Phase 2 studies. However, the induction of anti-OspA IgG (anti-outer surface protein A immunoglobulin G) antibody titers was higher in participants who received the three-dose primary series compared to those who received the two-dose primary series, supporting the use of a three-dose primary series schedule in the planned Phase 3 clinical trial. The VLA15-221 trial is ongoing to assess the safety and immunogenicity of VLA15 in 5-17 year olds. Initial pediatric data are expected in the first half of 2022.

The analysis was also consistent with the acceptable safety and tolerability profile observed in previous studies of VLA15. No vaccine-related serious adverse events (SAEs) were observed.

Juan Carlos Jaramillo M.D., Chief Medical Officer von Valneva, sagte: “I’m very pleased with these results, which are critical for determining the optimal vaccination schedule for our planned Phase 3 trial. In partnership with Pfizer, we are excited to further investigate this vaccine candidate, which will hopefully help provide protection against Lyme disease for both adults and children.”

Kathrin U. Jansen, Ph.D., Senior Vice President and Head of Vaccine Research & Development at Pfizer, said: “Lyme disease is increasingly impacting people throughout the northern hemisphere, potentially due to environmental changes and more active outdoor lifestyles. The continued positive data from the VLA15-221 trial support the ongoing development of this vaccine candidate, and we look forward to continuing to work with Valneva to potentially help protect people against Lyme disease.”

Über VLA15

VLA15 ist der einzige Lyme Borreliose-Impfstoffkandidat, der sich derzeit in der klinischen Entwicklung befindet. Dieser Impfstoffkandidat mit multivalenten Proteinuntereinheiten nutzt einen etablierten Wirkmechanismus für einen Borreliose-Impfstoff, der auf das äußere Oberflächenprotein A (OspA) von Borrelia burgdorferi, the bacteria that cause Lyme disease. OspA is one of the most dominant surface proteins expressed by the bacteria when present in a tick. The vaccine covers the six OspA serotypes expressed by Borrelia burgdorferi sensu lato species that are prevalent in North America and Europe. 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 20171. Valneva and Pfizer entered into a collaboration agreement in April 2020 to co-develop VLA15.2

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.

294 healthy adult participants received VLA15 at two different immunization schedules (month 0-2-6 [N=97] or month 0-6 [N=90]) or three doses of placebo (month 0-2-6 [N=107]). Vaccine recipients received VLA15 at a dose of 180 µg, which was selected based on data generated in the two previous Phase 2 studies. The main safety and immunogenicity readout in adults was performed at month 7. A subset of participants will receive a booster dose of VLA15 or placebo at month 18 (booster phase) and will be followed for three additional years to monitor antibody persistence. The VLA15-221 trial is ongoing to assess the safety and immunogenicity of VLA15 in a pediatric population aged 5 years and above.

VLA15 is tested as an alum-adjuvanted formulation and administered intramuscularly. The study is conducted at sites located in areas where Lyme disease is endemic and has enrolled volunteers with a cleared past infection with Borrelia burgdorferi als auch Freiwillige ohne eine frühere Borrelia burgdorferi-Infektion aufgenommen.

Über Lyme Borreliose

Die Lyme-Borreliose ist eine systemische Infektion, die durch das Bakterium Borrelia burgdorferi verursacht wird und durch infizierte Ixodes -Zecken auf den Menschen übertragen wird3. Sie gilt als die häufigste durch Vektoren übertragene Krankheit in der nördlichen Hemisphäre. Die tatsächliche Häufigkeit der Lyme-Borreliose ist zwar nicht bekannt, doch schätzt man, dass jährlich etwa 476 000 Menschen in den Vereinigten Staaten4 und 130 000 Menschen in Europa5. 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 widens6.
