A Safety and Immunogenicity Study of CHIKV VLP Vaccine in Children.

The goal of this multi-center, randomized, double-blind, placebo-controlled study is to evaluate the safety and immunogenicity of CHIKV VLP Vaccine in children 1 to \<12 years of age.

An Efficacy, Safety, and Immunogenicity Study of CHIKV VLP Vaccine for the Prevention of Chikungunya Disease in Adolescents and Adults

Study EBSI-CV-317-007 is a field study to evaluate the efficacy, immunogenicity, and safety of CHIKV VLP vaccine. The study was designed using infectious disease models and advanced analytics to guide region and clinical site prioritization, define the timing of study activities, and optimize the study parameters to local epidemiological conditions for CHIKV disease to overcome the challenges of assessing efficacy for CHIKV VLP vaccine.

A Phase I Study of PepGNP-ChikV in Healthy Volunteers

This is a Phase I, randomized, single-blind, placebo-controlled, study of four separate dose cohorts, with a 42-day interval between each vaccine dose, of a novel Chikungunya Peptide Immunotherapy Vaccine in Healthy Adults (18-60 years of age). All participants will undergo a screening visit scheduled for a maximum of 28 days before the enrolment in the clinical study and will provide a blood sample for clinical laboratory tests (complete blood count (CBC)\*, platelet count, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, serum creatinine and activated partial thromboplastin time (aPTT), human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV)), and a urine sample for tests for Urinary protein, Urinary blood, Urinary glucose and human chorionic gonadotropin β-subunit (βhCG) urine test (only the female participants)) in order to confirm their eligibility for participation in the study. A total of 40 participants are planned to be enrolled. A randomization system will be used to assign treatment group and participant number at the clinical site. Participants will receive 2 injections, 42 days apart. A final visit will take place at Day 407 (i.e. 365 days after last vaccination). Participants will be kept under observation for 30 minutes after each vaccination to ensure their safety. Reactogenicity data will be collected in all participants after each vaccine injection: solicited injection site reactions will be collected for Days 0-10 and Days 42-52 and solicited systemic reactions will be collected for Days 0-21 and Days 42-63. Unsolicited events will be collected for Days 0-52. Serious adverse events (SAEs) will be reported throughout the study (from inclusion until 12 months after last vaccination). Serious and non-serious medically attended adverse events (MAAEs) and adverse events of special interest (AESIs) will be collected throughout the study (from inclusion until 12 months after last vaccination).
