The clinical study will focus on identifying the most suitable doses of the vaccine candidate in regard to immunogenicity, safety, and tolerability. Therefore up to 48 healthy volunteers will participate in the study and three different treatment regimens will be compared with a placebo treatment. One treatment group will receive one injection of high dose vaccine, the other two groups will receive two shots of either high dose or low dose vaccine. Results of all groups are expected within the next six months. The study will be conducted at the “Department of Clinical Pharmacology” and the “Institute of Specific Prophylaxis and Tropical Medicine” at the Medical University of Vienna, Austria.
What is Zika Virus?
Zika is a viral infection transmitted by mosquitoes. It originates in Asia and parts of Africa but the increase in global traveling and rising temperatures may cause it to spread into more temperate zones. Recently, the virus spread across the Pacific Ocean to the Americas, leading to the 2015/16 virus epidemic.
Themis Bioscience GmbH develops prophylactic vaccines from the preclinical to the early clinical phase, focusing on emerging tropical infectious diseases, with initial vaccine candidates currently being developed against Chikungunya and Zika. The company’s highly innovative and fully patent-protected measles virus vaccine vector technology platform, licensed from the internationally respected Institut Pasteur in Paris, forms the basis for all current vaccine candidates of the Vienna-based company.
