|Condition or disease||Intervention/treatment||Phase|
|Chikungunya Virus Infection||Biological: MV-CHIK Other: Placebo||Phase 2|
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||60 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||Prospective, placebo controled, randomized, double-blinded, interventional, safety study|
|Masking:||Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)|
Study medication is available as liquid frozen vaccine product or saline for injection (placebo).
The actual study injections will be prepared by an unblinded team member (e.g. pharmacy personnel) and will be forwarded to the investigator (injector) in a blinded fashion (injection ready syringes containing either verum or placebo). The injector, study subjects, or other site personnel are not informed about the study treatment until unblinding may occur.
|Official Title:||Phase 2 Study of a Live Attenuated Measles Virus-Vectored Chikungunya Vaccine in Previously Exposed Adults|
|Actual Study Start Date :||July 16, 2019|
|Estimated Primary Completion Date :||March 4, 2021|
|Estimated Study Completion Date :||March 4, 2021|
Experimental: Treatment Arm
Subjects randomized to the treatment arm will receive two vaccinations with MV-CHIK, a recombinant live Schwarz-strain measles-vectored vaccine expressing chikungunya virus structural proteins. The vaccinations will be provided on days 0 and 28 after enrollment.
Liquid frozen, life attenuated, measles vectored Chikungunya vaccine; 5E+05 TCID50 (+/- 0.5 log) per dose.
Placebo Comparator: Placebo Arm
Subjects randomized to the placebo arm will receive two injections of sterile physiological saline. The injections will be provided on days 0 and 28 after enrollment.
Sterile physiological saline for injection
- Frequency of Adverse Events [ Time Frame: 28 weeks ]Incidence of solicited and unsolicited adverse events from enrollment until end of study.
- Chikungunya Antibody Titer [ Time Frame: 28 weeks ]Geometric mean titer (GMT) of neutralizing antibodies to chikungunya evaluated on days 0, 28, 56, and at the end of the study.
