Favorable VLA15 Phase 2 Study Results Might Boost VALN Stock

Read MoreHide Full Article

Valneva SE (VALN - Free Report) and Pfizer Inc. recently reported positive immunogenicity and safety data from their VLA15-221 Phase 2 study. Data from the study showed a strong immune response one month after a second booster dose in pediatric and adult populations.

The safety and tolerability profile of VLA15 after a second booster dose was compared with that observed after the first booster. No safety concern was observed by an independent Data Monitoring Committee (“DMC”) in any treatment or age group.

The new favorable data from the Phase 2 trial helped Valneva advance the furthest along the clinical development timeline. In line with this, two Phase 3 trials for VLA15 are in progress.

About Valneva’s VLA15

VLA15 is an investigational multivalent protein subunit vaccine that uses an established mechanism of action for a Lyme disease vaccine. It targets the outer surface protein A (OspA) of Borrelia burgdorferi — the bacteria that causes Lyme disease. The vaccine candidate covers the six most prevalent OspA serotypes expressed by the Borrelia burgdorferi sensu lato species in North America and Europe.

For investors’ note, Lyme disease is a systemic infection caused by Borrelia burgdorferi bacteria transmitted to humans from the bite of infected Ixodes ticks. It is considered the most common vector-borne illness in the Northern Hemisphere.According to the Centers for Disease Control and Prevention (“CDC”), approximately 476,000 people in the United States are diagnosed and treated for Lyme disease each year. 129,000 such cases are reported annually in Europe.

About Valneva’s VLA15-221 Phase 2 study

The participants of this Phase 2 study received VLA15 during the primary vaccination phase in two immunization schedules — months 0-2-6 or months 0-6, followed by a first booster dose at month 18 and a second at month 30.

The latest results from the VLA15-221 Phase 2 study demonstrate a significant anamnestic antibody response across all six serotypes covered by the vaccine candidate in pediatric (5 to 11 years of age) and adolescent (12 to 17 years of age) participants, as well as in adults (18 to 65 years of age). The study was measured one month after the administration of the second booster dose.

A large number of participants seroconverted after the second booster dose, yielding seroconversion rates* (SCRs) above 90% for all outer surface protein A (OspA) serotypes in all age groups. The response was in line with the results achieved from SCRs after the first booster. Geometric Mean Titers at one month post the first and second boosters were comparably high.

More on Valneva’s Clinical Study for VLA15

In 2022, Pfizer and Valneva initiated the currently ongoing Phase 3 clinical study — vaccine against Lyme for outdoor recreationists (VALOR). The study is aimed at investigating the efficacy, safety and immunogenicity of VLA15 in participants five years of age and older in highly endemic regions in the United States and Europe. 

The initial vaccination series for all participants was completed in July 2024. A second Phase 3 study (VLA15-1012) is also in progress. The second Phase 3 study is aimed at providing further evidence on the safety profile of VLA15 in the pediatric population.

Pfizer also expects to submit a Biologics License Application (“BLA”) to the Food and Drug Administration (“FDA”) and a Marketing Authorization Application (“MAA”) to the European Medicines Agency (“EMA”) in 2026, subject to positive Phase 3 data.

Other Recent Developments by Valneva

Last month, Valneva entered into a strategic partnership and exclusive licensing agreement with LimmaTech Biologics AG for the development, manufacturing and commercialization of Shigella4V (S4V). S4V is a tetravalent bioconjugate vaccine candidate against shigellosis.

Under the terms of the agreement, LimmaTech will receive an upfront payment and be eligible for future milestone and royalty payments. It will be responsible for conducting a Phase 2 Controlled Human Infection Model (“CHIM”) and a Phase 2 pediatric study for S4V.

In July, VALN expanded its partnership with the Coalition for Epidemic Preparedness Innovations (“CEPI”) to support broader access to the IXCHIQ - chikungunya vaccine, in Low- and Middle-Income countries (“LMICs”). Valneva will receive funding from CEPI to support clinical trials in vulnerable groups, such as children and pregnant women. The partnership will also support technology transfer to an additional manufacturer to supply IXCHIQ to Asian LMICs.
