Phase I Study to Evaluate Basic Pharmacodynamic, Pharmacological and Toxicological Effects of the Newly Developed Crimean-Congo Hemorrhagic Fever Vaccine for Humans
October 16, 2017 updated by: Aydin Erenmemisoglu, The Scientific and Technological Research Council of Turkey
Phase I Study to Evaluate Basic Pharmacodynamic, Pharmacological and Toxicological Effects of the Newly Developed Crimean-Congo Hemorrhagic Fever Vaccine for Humans, Prepared in Cell Culture and Inactivated With Formalin, and Administered Subcutaneously or Intramuscularly With Two Different Doses
This study covers the first trial of the Crimean-Congo Hemorrhagic fever virus (CKKA) vaccine on humans (healthy volunteers), which has been developed in Turkey and has completed preclinical toxicology studies to be performed on experimental animals.
Also, this study is a Phase I, randomized, double-blind, national, single-center, placebo-controlled study that is designed to evaluate the safety and efficacy of the CKKA vaccine.
A total of 60 (12 + 48) healthy male and/or female volunteers will be participating in this study, and the study is planned to last approximately one year.
