SAN DIEGO--(BUSINESS WIRE)--Arcturus Therapeutics Holdings Inc. (the “Company”, “Arcturus”, Nasdaq: ARCT), a leading clinical-stage messenger RNA medicines company focused on the development of infectious disease vaccines and significant opportunities within liver and respiratory rare diseases, today announced that the Vietnam Ministry of Health has approved initiation of the Phase 3b part of the placebo-controlled, observer-blind Phase 1/2/3 clinical trial of ARCT-154 self-replicating RNA vaccine targeting the SARS-CoV-2 delta variant and other variants of concern. Arcturus Therapeutics and Vinbiocare remain on track to potentially file an Emergency Use Authorization (EUA) for ARCT-154 in Vietnam in December 2021.
ARCT-154 Phase 3b study dosing has been initiated and the trial is expected to enroll approximately 20,000 participants with half of the participants receiving ARCT-154 under a two-dose regimen with injections 28 days apart, while the other half will receive placebo. The Phase 1 part of the trial has completed the priming vaccination series with two administrations in 100 participants (75 in ARCT-154 arm). The Phase 2 and Phase 3a parts of the trial are ongoing with 300 (225 in ARCT-154 arm) and 600 (450 in ARCT-154 arm) participants, respectively.
The approval to proceed with the Phase 3b portion of the study follows the review of safety data from the initial 1,000 participants included in the Phase 1/2/3a cohorts of the ARCT-154 study.
“I am very pleased with the progress, including the rapid enrollment and dosing in the ARCT-154 trial. Initiation of dosing in the Phase 3b portion of the study brings us one step closer to our goal of filing for EUA and making it available as quickly as possible,” said Joseph Payne, President and CEO of Arcturus Therapeutics. “As a low dose vaccine targeting variants of concern, ARCT-154 has a differentiated profile compared to currently available vaccines and we believe that our program has the potential to become a best-in-class option for Vietnam and many other countries around the world.”
