Commences recruitment of Adolescents into Phase 3 trial “Cov-Compare”
Enrolls participants in the Phase 1/2 Booster Trial
Saint-Herblain (France), September 23, 2021 – Valneva SE, (Nasdaq: VALN; Euronext Paris: VLA) a specialty vaccine company, today announced that it has commenced recruitment of adolescents in its pivotal Phase 3 Clinical Trial (VLA2001-301, “Cov-Compare”) for its inactivated COVID-19 vaccine candidate VLA2001 in the United Kingdom. Topline results from the pivotal Cov-Compare trial are expected early in the fourth quarter of 2021 and are intended to form the basis for potential regulatory approval in adults. The Company has also started to provide boosters to volunteers in its Phase 1/2 VLA2001-201 trial. This planned expansion of VLA2001 clinical trials will support future approval in further age groups, in addition to adults.
Recruitment of adolescents, aged 12 to 17 years, has commenced in the United Kingdom as part of Valneva’s pivotal Cov-Compare Phase 3 trial (VLA2001-301). An initial cohort of adolescents will be enrolled in an open label, non-randomized format. Subject to safety review, remaining participants will be randomized to receive two doses of either VLA2001 or a placebo 28 days apart, followed by a booster dose seven months after enrolling into the study. Approximately 660 participants will be recruited for this trial. Participants randomized to the placebo arm will have the opportunity to receive a course of VLA2001 following the initial safety assessment. A further expansion of the study to include volunteers younger than 12 years old is also envisaged, subject to data from the adolescent group.
Valneva has also commenced booster vaccinations as a continuation of the Phase 1/2 VLA2001-201 trial for which the Company reported positive topline data in April 20211. The booster shot will be provided to each volunteer six months after initial vaccination.
Valneva is conducting several clinical trials of VLA2001. In addition to Cov-Compare and VLA2001-201, VLA2001 is being evaluated in elderly volunteers in study VLA2001-304 in New Zealand as well as in a small, policy-led trial sponsored by University Hospital Southampton NHS Foundation Trust which is not part of Valneva’s regulatory package.
Valneva continues discussions with the European Commission regarding a potential VLA2001 supply contract. The Company is also actively pursuing opportunities to make VLA2001 available to other customers, subject to positive Cov-Compare data and regulatory approval.
Thomas Lingelbach, Chief Executive Officer of Valneva, commented, “Our teams at Valneva remain fully committed to carry out VLA2001’s development plan and bring our inactivated vaccine to all patient groups who could benefit. We continue to receive messages on a daily basis from people across the world who are waiting for an inactivated vaccine so we continue to believe that our differentiated vaccine candidate could contribute to the ongoing fight against the COVID-19 pandemic. We’re confident that many countries, and regulators, will want to have the opportunity to consider our inactivated COVID-19 vaccine.”
VLA2001 is currently the only whole virus, inactivated, adjuvanted vaccine candidate in clinical trials against COVID-19 in Europe. It is intended for active immunization of at-risk populations to prevent carriage and symptomatic infection with COVID-19 during the ongoing pandemic and potentially later for routine vaccination including addressing new variants. VLA2001 may also be suited for boosting, as repeat booster vaccinations have been shown to work well with whole virus inactivated vaccines. VLA2001 is produced using Valneva’s established Vero-cell platform, leveraging the manufacturing technology for Valneva’s licensed Japanese encephalitis vaccine, IXIARO®. VLA2001 consists of inactivated whole virus particles of SARS-CoV-2 with high S-protein density, in combination with two adjuvants, alum and CpG 1018. This adjuvant combination has consistently induced higher antibody levels in preclinical experiments than alum-only formulations and shown a shift of the immune response towards Th1. CpG 1018 adjuvant, supplied by Dynavax Technologies Corporation (Nasdaq: DVAX), is a component of the US FDA- and EMA-approved HEPLISAV-B® vaccine. VLA2001’s manufacturing process, which has already been upscaled to final industrial scale, includes chemical inactivation to preserve the native structure of the S-protein. VLA2001 is expected to conform with standard cold chain requirements (2 to 8 degrees Celsius).
