Valneva Reports Positive 24-Month Antibody Persistence Data for its Single-Shot Chikungunya Vaccine IXCHIQ®

  • Primary endpoint met with 97% seroresponse rate 24 months after a single vaccination
  • Antibody levels remained high and well above the seroresponse threshold, further supporting the anticipated long-term durability of the immune response
  • No safety concerns identified in long-term follow up

Saint-Herblain (France), December 4, 2023 – Valneva SE (Nasdaq: VALN; Euronext Paris: VLA), a specialty vaccine company, today reported positive antibody persistence data twenty-four months after vaccination with a single dose of its chikungunya vaccine IXCHIQ®, further supporting the anticipated long-term durability of the immune response and in line with positive twelve-month persistence data the Company reported in December 20221. These persistence data are intended to supplement the existing approval by U.S. FDA and ongoing regulatory approval processes.

97% of the 316 healthy adults still enrolled in the trial retained neutralizing antibody titers above the seroresponse threshold2 twenty-four months after the single-dose vaccination. The persistence of antibodies in older adults aged 65 and above was as robust as in younger adults, and even slightly higher in terms of geometric mean titers (GMTs) and seroconversion rates (SRRs). This outcome underscores the vaccine's potential to offer strong and lasting protection against chikungunya across different age groups. These results follow completion of the pivotal Phase 3 study published in the Lancet3 in which a seroresponse rate of 96% six months after a single vaccination1 was reported.

Study VLA1553-303 collected long-term safety by following any Adverse Event of Special Interest (AESI) from the preceding study and collecting new-onset SAEs. No safety concerns were identified for the duration of the 24-month follow-up and, as reported in the 12-months data analysis, no AESI was ongoing when participants were enrolled in the trial.

Juan Carlos Jaramillo M.D., Chief Medical Officer of Valneva, said, “We are very pleased about these twenty-four-month data which confirm IXCHIQ®'s ability to induce a robust, long-lasting antibody response in both younger and older adults with a single vaccination. Being the world's first approved vaccine against chikungunya, each positive outcome further strengthens the defense against this significant and expanding public health threat.”

Valneva was granted U.S. FDA approval4 for its chikungunya vaccine IXCHIQ® in November 20235. Two marketing applications are currently under review by EMA and Health Canada with potential approvals in mid-2024. A clinical study in adolescents is also ongoing in Brazil for which the Company reported positive pivotal Phase 3 data in November 20236. This study is intended to support label extension in this age group and licensure of the vaccine in Brazil, which would be the first potential approval for use in endemic populations.

About Chikungunya
Chikungunya is a mosquito-borne viral disease caused by the chikungunya virus (CHIKV), a Togaviridae virus, transmitted by Aedes mosquitoes. Infection leads to symptomatic disease in up to 97% of humans after four to seven days following the mosquito bite7. While mortality with CHIKV is low, morbidity is high, and the global market for vaccines against chikungunya is estimated to exceed $500 million annually by 20328. Clinical symptoms include acute onset of fever, debilitating joint and muscle pain, headache, nausea, rash and chronic arthralgia. Chikungunya virus often causes sudden large outbreaks with high attack rates, affecting one-third to three-quarters of the population in areas where the virus is circulating. The high-risk areas of infection for travelers are places where chikungunya virus-carrying mosquitos are endemic, including the Americas, parts of Africa, and Southeast Asia, and the virus has spread to more than 110 countries9. Between 2013 and 2023, more than 3.7 million cases were reported in the Americas10 and the economic impact is considered to be significant. The medical and economic burden is expected to grow as the CHIKV primary mosquito vectors continue to spread geographically. Before IXCHIQ®, there were no preventive vaccines or effective treatments available and, as such, chikungunya is considered to be a major public health threat.

About IXCHIQ®
In the U.S., IXCHIQ® is a live-attenuated vaccine indicated for the prevention of disease caused by chikungunya virus (CHIKV) in individuals 18 years of age and older who are at increased risk of exposure to CHIKV. As for all products approved under FDA’s accelerated approval pathway, continued approval for this indication is contingent upon verification and description of clinical benefit in confirmatory studies.

IXCHIQ® (chikungunya virus, live) Solution for Intramuscular Injection

Indication
IXCHIQ® is a vaccine indicated for the prevention of disease caused by chikungunya virus (CHIKV) in individuals 18 years and older who are at increased risk of exposure to CHIKV. This indication is approved under accelerated approval based on anti-CHIKV neutralizing antibody titers. Continued approval for this vaccine is contingent upon verification and description of clinical benefit in confirmatory studies.

IMPORTANT SAFETY INFORMATION ABOUT IXCHIQ® – Please consult the full prescribing information for all the labeled safety information.

Contraindications
IXCHIQ® should not be given to individuals who have a weakened immune system due to medications used for hematologic and solid tumors, on chemotherapy, history of congenital immunodeficiency, long-term immunosuppressive therapy, or patients with HIV infection who are severely immunocompromised.

Individuals with a history of a severe allergic reaction to any component of the vaccine.

Warnings
Appropriate medical treatment used to manage immediate allergic reactions must be available in the event an acute anaphylactic reaction following administration of IXCHIQ® or any vaccine.

Vaccination with IXCHIQ® may cause severe or prolonged chikungunya-like adverse reactions. Severe chikungunya-like adverse reactions that prevented daily activity and/or required medical intervention occurred in 1.6% of 3,082 IXCHIQ® recipients and no placebo recipients. Fourteen IXCHIQ® recipients had prolonged (duration at least 30 days) chikungunya-like adverse reactions.

Infection of pregnant individuals with wild-type chikungunya virus can result in intra-partum transmission and potentially fatal neonatal complications. IXCHIQ® should be administered during pregnancy only after an individual risk-benefit assessment, considering maternal risk of chikungunya infection and gestational age.

Fainting can occur with administration of IXCHIQ®. Procedures should be in place to avoid injury from fainting.

IXCHIQ® may not protect all individuals who receive the vaccine.

Adverse Reactions
The most common injection site reaction (>10%) was tenderness (11%) and the most common systemic adverse reactions (>10%) were headache (31%), fatigue (29%), myalgia (24%), arthralgia (17%), fever (13%) and nausea (11%).

Use in Specific Populations

Pregnancy

There are no adequate and well-controlled studies of IXCHIQ® in pregnant individuals, and human data available from clinical trials with IXCHIQ® are insufficient to establish the presence or absence of vaccine-associated risk during pregnancy.

About Phase 3 trial VLA1553-303
VLA1553-303 is a single-arm, open label Phase 3 trial evaluating antibody persistence in 363 participants aged 18 years or above who were immunized with VLA1553 during the pivotal trial VLA1553-301. The primary objective of the trial is to evaluate the persistence of antibodies annually from one to five years after the single immunization with VLA1553. Study VLA1553-303 collected long-term safety by following-up any Adverse Event of Special Interest (AESI) from the preceding clinical study and collecting new-onset SAE up to two years. When participants joined the follow-up study, no AESI was ongoing.
Additional information, including a detailed description of the trial design, eligibility criteria and investigator sites, is available at ClinicalTrials.gov (Identifier: NCT04546724).

Pfizer and Valneva Complete Recruitment for Phase 3 VALOR Trial for Lyme Disease Vaccine Candidate, VLA15

  • 9,437* participants enrolled at sites across the U.S., Europe and Canada in areas where Lyme disease is endemic
  • Trial conclusion expected by year-end 2025
  • Pfizer aims to submit regulatory filings in the U.S. and Europe in 2026

New York, NY, and Saint-Herblain (France), December 4, 2023 – Pfizer Inc. (NYSE: PFE) and Valneva SE (Nasdaq: VALN; Euronext Paris: VLA) today announced that they have completed recruitment for the Phase 3 trial Vaccine Against Lyme for Outdoor Recreationists (VALOR) (NCT05477524) for Lyme disease vaccine candidate VLA15. The trial builds on previous positive Phase 1 and 2 trial results and includes both adult and pediatric participants, with the aim to confirm the efficacy, safety, lot consistency, and immunogenicity of VLA15.

“We are pleased that the Phase 3 trial recruitment is complete. Lyme disease is the most prevalent vector-borne infectious disease in the United States and Europe, can sometimes even lead to long lasting consequences,” said Annaliesa Anderson, Ph.D., Senior Vice President and Head Vaccine Research and Development, Pfizer. “If approved, a vaccine could prevent the disease and ease the burden of acute, severe and sometimes persistent consequences in both adults and children. We look forward to progressing the trial with the goal of submitting a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) and Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) in 2026, subject to positive data.”

Juan Carlos Jaramillo M.D., Chief Medical Officer of Valneva, said: “The completion of enrollment is indeed an important milestone in the development of a potential vaccine for Lyme disease. VLA15 has the potential to address a high need in North America and Europe, as it has been designed to offer coverage for the most common circulating types of Borrelia bacteria that cause Lyme disease in these regions. We’re excited about the ongoing trials and the progress towards potentially offering a vaccine against this disease which can result in debilitating sequelae and excessive healthcare usage.”

The VALOR trial, which was initiated in August 2022, has enrolled 9,437* participants five years of age and older, at sites in areas where Lyme disease is highly endemic across the U.S., Europe and Canada. As part of the primary series, participants receive three doses of VLA15 or a saline placebo (1:1 ratio) within the first year, and one booster dose approximately one year after completion of the primary immunization.

The VLA15 candidate has demonstrated a strong immune response and had a favorable safety profile across all dose and age groups in pre-clinical and clinical trials so far.1,2 No vaccine-related serious adverse events (SAEs) and no safety concerns were observed by an independent Data Safety Monitoring Board (DSMB).1,2 A second Phase 3 trial (C4601012), aiming to provide further evidence on the safety profile of VLA15 in the pediatric population, is also fully recruited.

The VALOR trial is expected to be concluded by the end of 2025. Pfizer and Valneva entered into a collaboration agreement in April 2020 to co-develop VLA15, with updates to the terms within this agreement made in June 2022.3,4

About VLA15
There are currently no approved human vaccines for Lyme disease, and VLA15 is the most advanced Lyme disease vaccine candidate currently in clinical development, with two Phase 3 trials in progress. 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 candidate covers the six most common OspA serotypes expressed by the Borrelia burgdorferi sensu lato species that are prevalent in North America and Europe. VLA15 is an alum-adjuvanted formulation, administered intramuscularly and has demonstrated a strong immune response as well as satisfactory safety profile in pre-clinical and clinical trials so far.

About the VALOR trial
VALOR is an ongoing randomized, observer-blind, placebo-controlled Phase 3 trial which has enrolled 9,437* participants 5 years of age and older to receive VLA15 or a saline placebo (1:1 ratio). As part of the primary series, participants receive three doses of VLA15 within the first year at months 0, 2 and 5-9, and one booster dose 9-12 months after completion of the primary immunization.5 The final primary series vaccination for participants occurs just before the peak Lyme disease season for the region. Participants will be followed for the occurrence of Lyme disease. The trial is conducted at sites located in areas where Lyme disease is highly endemic across the U.S., Canada and Europe and has enrolled volunteers with a cleared past infection with Borrelia burgdorferi as well as Borrelia burgdorferi naïve volunteers.

About Lyme Disease
Lyme disease is a systemic infection caused by Borrelia burgdorferi bacteria transmitted to humans by the bite of an infected Ixodes ticks.6 It is considered the most common vector-borne illness in the Northern Hemisphere.7,8 While the true incidence of Lyme disease is unknown, it is estimated to annually affect approximately 476,000 people in the U.S. and 129,000 people in Europe.8,9 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 chronic complications affecting the skin, joints (arthritis), the heart (carditis) or the nervous system.9,10 The medical need for vaccination against Lyme disease is steadily increasing as the geographic footprint of the disease widens.11
