VALNEVA Receives FDA Fast Track Designation for its Lyme Disease Vaccine Candidate VLA15

  • Lyme disease is the fastest growing vector-borne infectious disease in the United States, according to the CDC;
  • Currently, there is no vaccine available to protect humans against Lyme disease and VLA15 is the only candidate in clinical development;
  • Valneva recently completed Phase I subject enrollment and expects to announce first results in Q1 2018;  
  • The Company aims to accelerate VLA15's development and plans to initiate a Phase II trial in Q1 2018; 
  • Fast track designation may offer a faster way to market approval through frequent  interactions with the FDA

LYON, France I July 24, 2017 I Valneva SE ("Valneva" or "the Company"), a fully integrated, commercial stage biotech company focused on developing innovative lifesaving vaccines, today announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation for its Lyme disease vaccine candidate VLA15.

Fast Track designation is granted by the FDA to products that are under development for serious conditions and have the potential to fulfill an unmet medical need. It is designed to facilitate the clinical development and expedite the review of new drugs and vaccines with the intention to accelerate the availability of promising products on the market[1].

Thomas Lingelbach, President and CEO of Valneva commented, "Lyme disease affects an increasing number of people each year, many of whom have to live with long-term sequelae that are not only extremely difficult to treat but also represent a heavy health economic burden. We feel privileged to advance the only active clinical stage Lyme vaccine candidate to date and are looking forward to working closely with the FDA and other authorities to facilitate the development towards approval."

Valneva recently completed subject enrollment for the ongoing Phase I study of its Lyme disease vaccine candidate. The study is being conducted at three sites - two in the U.S. and one in Europe (Belgium) - combining approximately 180 subjects aged between 18 and 40 years. The primary objective of the observer-blind, partially randomized, dose escalation study is to evaluate the vaccine candidate's safety and tolerability profile at different dose levels and formulations. Immunogenicity, measured by observing IgG antibodies[2] against the six most prevalent serotypes of Lyme borreliosis in the US and Europe present in the vaccine, will also be monitored for different dose groups and formulations at different time-points.

Given the steady increase in the incidence of the disease and its spread to new territories, Valneva is committed to accelerate the development of VLA15 as a novel prevention against such a high-priority medical need. As such, the company plans to initiate Phase II as early as the first quarter of 2018. 

Pre-clinical data showed that Valneva's vaccine candidate had the potential to provide protection against the majority of Borrelia species pathogenic for humans[3].

About Lyme disease

Lyme disease (LD), also known as Lyme borreliosis, is an infectious disease caused by Borrelia bacteria which are transmitted to humans by infected ticks. Early symptoms of Lyme disease (such as a gradually expanding erythematous rash called Erythema migrans or more unspecific symptoms like fatigue, fever, headache, mild stiff neck, arthralgia or myalgia) are often overlooked or misinterpreted. When treatment for LD is delayed or inadequate, infection with Borrelia can lead to serious complications involving the joints, heart and central nervous system. Each year, an estimated 300,000 US citizens[4] and 85,000 Europeans[5] develop Lyme disease. It was diagnosed as a separate condition for the first time in 1975 in Old Lyme, Connecticut.

About VLA15

VLA15 is a new hexavalent, protein subunit-based vaccine candidate targeting the Outer Surface Protein A (OspA) of Borrelia, the most dominant protein expressed by the bacteria when present in a tick. By targeting the most prevalent serotypes of Borrelia and blocking the transmission of these Lyme-causing bacteria from the tick to the host, the vaccine has the potential to protect from Borrelia infection in the U.S., Europe, and potentially worldwide. The target indication for Valneva's vaccine candidate is the active prophylactic immunization against Lyme disease in children and adults. The global market for a vaccine against Lyme disease is estimated at approximately €700 - €800 million annually[6].
