Saint-Herblain (France), September 14, 2021 – Valneva SE, a specialty vaccine company, today announced that it has completed recruitment of the initial cohort of elderly participants in Valneva’s Phase 3 trial, VLA2001-304, of its inactivated COVID-19 vaccine candidate, VLA2001.
300 volunteers aged 56 years and older have been recruited in New Zealand into the VLA2001-304 trial with the objective to generate further safety and immunogenicity data for this age group. The cohort size has been increased to 300, from 150, in consultation with the European Medicines Agency (“EMA”). Topline data from this cohort will read out in early 2022, and it is expected that the data will support additional regulatory submissions.
Juan Carlos Jaramillo, M.D., Chief Medical Officer of Valneva, commented, “We initiated this trial approximately a month ago, so we are extremely pleased to achieve this important milestone in such a short period of time. We believe that our differentiated vaccine candidate can make a major contribution to the ongoing fight against the COVID-19 pandemic.”
VLA2001 is currently the only inactivated vaccine candidate in clinical trials against COVID-19 in Europe. In parallel to the VLA2001-304 trial in New Zealand, VLA2001 is currently being studied in the United Kingdom (UK) in a pivotal Phase 3 trial, “Cov-Compare” (VLA2001-301), for which top-line results are currently expected early in the fourth quarter 2021. Valneva has commenced rolling submission for conditional approval with the UK’s Medicines and Healthcare products Regulatory Agency (MHRA).
VLA2001 ist derzeit der einzige inaktivierte, adjuvantierte Ganzvirus-Impfstoffkandidat gegen COVID-19 in Europa. Er ist für die aktive Immunisierung von Risikopopulationen zur Verhinderung der Einschleppung und symptomatischen Infektion mit COVID-19 während der laufenden Pandemie und möglicherweise später für die Routineimpfung sowie zur Bekämpfung neuer Varianten vorgesehen. VLA2001 kann auch für Booster-Impfungen geeignet sein, da sich wiederholte Booster-Impfungen mit inaktivierten Ganzvirusimpfstoffen als gut wirksam erwiesen haben. VLA2001 wird auf Valnevas etablierter Vero-Zell-Plattform hergestellt, die die Herstellungstechnologie von Valnevas lizenziertem Impfstoff gegen Japanische Enzephalitis, IXIARO®®, nutzt. VLA2001 besteht aus inaktivierten ganzen Viruspartikeln von SARS-CoV-2 mit hoher S-Protein-Dichte, in Kombination mit zwei Adjuvantien, Alum und CpG 1018. Diese Adjuvans-Kombination hat in präklinischen Experimenten konsistent höhere Antikörperspiegel induziert als reine Alum-Formulierungen und eine Verschiebung der Immunantwort in Richtung Th1 gezeigt. Das Adjuvans CpG 1018, bereitgestellt durch Dynavax Technologies Corporation (Nasdaq: DVAX), ist ein Bestandteil des von der US FDA und EMA zugelassenen Impfstoffs HEPLISAV-B® . Der Herstellungsprozess für VLA2001, der bereits auf den endgültigen industriellen Maßstab hochskaliert wurde, beinhaltet eine chemische Inaktivierung, um die native Struktur des S-Proteins zu erhalten. Der Impfstoff benötigt Standard-Kühlkettenbedingungen (2 Grad bis 8 Grad Celsius).
Trial VLA2001-304 is expected to enroll two cohorts. Cohort 1 includes 300 volunteers aged 56 years and older in an open-label manner in order to generate safety and immunogenicity data for VLA2001 in this age group. Cohort 2 of the trial is expected to include approximately 600 volunteers aged 12 years and older in order to compare immunogenicity data of Valneva’s original COVID-19 vaccine candidate, VLA2001, to an additional COVID-19 vaccine candidate, VLA2101, based on a variant strain to be confirmed. In both cohorts, vaccinations will be administered in a two-dose immunization schedule 28 days apart. The trial will be conducted at approximately 10 trial sites in New Zealand.

Über Valneva SE
Valneva is a specialty vaccine company focused on the development and commercialization of prophylactic vaccines for infectious diseases with significant unmet medical need. The Company takes a highly specialized and targeted approach to vaccine development, beginning with the identification of deadly and debilitating infectious diseases that lack a prophylactic vaccine solution and for which there are limited therapeutic treatment options. It then applies its deep understanding of vaccine science, including its expertise across multiple vaccine modalities, as well as its established vaccine development capabilities, to develop prophylactic vaccines to address these diseases. The Company has leveraged its expertise and capabilities both to successfully commercialize two vaccines and to rapidly advance a broad range of vaccine candidates into and through the clinic, including candidates against Lyme disease, COVID-19 and the chikungunya virus.
