Valneva’s Chief Executive Officer, Thomas Lingelbach, will provide an update and discuss next steps for VLA15, the Company’s vaccine candidate against Lyme disease. Lyme is the most commonly occurring vector borne illness in the Northern Hemisphere with an estimated 300,000 Americans contracting the disease each year1. VLA15 has been shortlisted in the “Best Prophylactic Vaccine” category of the 2019 Vaccine Industry Excellence (ViE) Awards, held in conjunction with the World Vaccine Congress each year.
Valneva’s Chief Medical Officer, Dr. Wolfgang Bender, will also present on the Phase 1 development of the Company’s chikungunya vaccine candidate, VLA1553. He will also discuss next steps for the potential single-shot vaccine.
Valneva, a gold sponsor of the event, will have a display in the exhibit area at booth #318.
Event: The World Vaccine Congress 2019, Washington, D.C.
Venue: Renaissance Washington D.C. Downtown Hotel
Date: Tuesday, April 16, 2019
Time: 11:40 a.m. EDT for the chikungunya presentation; 2:40 p.m. EDT for the Lyme presentation
Valneva’s vaccine candidate, VLA15, is currently the only active vaccine program in clinical development against Lyme disease. The program was granted Fast Track designation by the U.S. Food and Drug Administration (FDA) in July 20172 and Valneva reported final Phase 1 data and positive initial booster data in January 20193. VLA15 showed a favorable safety profile and was immunogenic in all doses and formulations tested with good OspA-specific IgG antibody responses against all OspA serotypes.
VLA15 is a multivalent, protein subunit vaccine that targets the outer surface protein A (OspA) of Borrelia. It is designed for prophylactic, active immunization against Lyme disease aiming for protection against the majority of human pathogenic Borrelia species. VLA15 is designed to confer protection by raising antibodies that prevent Borrelia from migrating from ticks to humans after a bite. The safety profile is expected to be similar to other vaccines using the same technology that have been approved for active immunization in adults and children.
The target population includes individuals at risk above 2 years of age living in endemic areas, people planning to travel to endemic areas to pursue outdoor activities and people at risk who have a history of Lyme disease (as infection with Borrelia does not confer protective immunity against all pathogenic Borrelia species).
Vaccination with OspA was already proven to work in the 1990s and VLA15 pre-clinical data showed that the vaccine has the potential to provide protection against the majority of the Borrelia species pathogenic for humans4.
VLA1553 is a monovalent, single dose, live-attenuated vaccine candidate for protection against chikungunya and was granted Fast Track designation by the U.S. Food and Drug Administration (FDA) in December 20185. The vaccine candidate is designed for prophylactic, active, singledose immunization against chikungunya in humans over one year old. The vaccine aims for long-lasting protection and an anticipated safety profile similar to licensed vaccines for active immunization in adults and children. The target population segments are travelers, military personnel and individuals at risk living in endemic regions. The global market for vaccines against chikungunya is estimated at up to €500 million annually6.
VLA1553 is based on an infectious clone (CHIKV LR2006-OPY1) attenuated by deleting a major part of the gene encoding the non-structural replicase complex protein nsP3, aiming for protection against various Chikungunya virus outbreak phylogroups and strains7.
In pre-clinical development, a single-vaccine shot was shown to be highly immunogenic in vaccinated Non-Human Primates (NHP) (cynomolgus macaques) and showed no signs of
viremia after challenge8. In NHPs, VLA1553 induced a strong, long lasting (more than 300 days) neutralizing antibody response comparable to wild-type CHIKV infections combined with a good safety profile.
