Study Description

Brief Summary:

This study is a randomized, double-blinded, Phase 1, placebo- controlled, and dose comparison trial to evaluate the safety, immunogenicity and schedule of MV-CHIK. Two dosage levels and 3 immunization schedules will be evaluated. This study will enroll up to 180 healthy subjects aged 18 to 45 years.Study duration is approximately 22 months. Subject participation duration is approximately 8-13 months. The primary objectives are to evaluate the safety and tolerability of 5 x 10^4 TCID50 and 5 x 10^5 TCID50 MV-CHIK and placebo following two consecutive intramuscular injections and to assess the CHIKV serum plaque reduction neutralization test (PRNT50) antibody responses to 5 x 10^4 TCID50, 5 x 10^5 TCID50 of MV-CHIK or placebo on day 29 following the first dose.

Detailed Description:

This study is a randomized, double-blinded, Phase 1, placebo- controlled, and dose comparison trial to evaluate the safety, immunogenicity and schedule of MV-CHIK. Two dosage levels (5 x 10^4 or 5 x 10^5 TCID50) and 3 immunization schedules (days 1 and 29, days 1 and 85 or days 1 and 169) will be evaluated. The study will have 6 cohorts, each with 30 subjects, 25 of whom will receive study vaccine and 5 of whom will receive placebo. Cohorts 1-3 will receive the low dosage of the lyophilized vaccine product (5 x 10^4 TCID50) and cohorts 4-6 will receive the high dosage (5 x 10^5 TCID50) of the lyophilized vaccine product. Each subject will receive two study injections using one of the three dosing schedules outlined above. This study will enroll up to 180 healthy subjects aged 18 to 45 years (inclusive). Subjects will be counseled on the study and will then sign an informed consent prior to any study procedures. Screening will be performed which will include evaluation of medical history, travel history to countries with known CHIKV circulation, medication history, a physical examination and safety laboratory evaluations. Study duration is approximately 22 months. Subject participation duration is approximately 8-13 months. The primary objectives are to evaluate the safety and tolerability of 5 x 10^4 TCID50 and 5 x 10^5 TCID50 MV-CHIK and placebo following two consecutive intramuscular injections and to assess the CHIKV serum plaque reduction neutralization test (PRNT50) antibody responses to 5 x 10^4 TCID50, 5 x 10^5 TCID50 of MV-CHIK or placebo on day 29 following the first dose. The secondary objectives are to assess the CHIKV serum plaque reduction neutralization test (PRNT50) antibody responses to 5 x 10^4 TCID50, 5 x 10^5 TCID50 MV-CHIK and or placebo using three dose schedules (days 1 and 29, days 1 and 85, or days 1 and 169) on day 29 following the second dose, assess CHIKV serum PRNT50 antibody responses to 5 x 10^4 TCID50, 5 x 10^5 TCID50 MV-CHIK or placebo on days 15, 85 and 169 following the second dose of vaccine, assess the CHIKV serum ELISA antibody responses to 5 x 10^4 TCID50, 5 x 10^5 TCID50 MV-CHIK or placebo on day 29 following the first dose of vaccine and days 15, 29, 85 and 169 following the second dose of vaccine, and to assess the durability of CHIKV serum ELISA and PRNT50 antibody responses to 5 x 10^4 TCID50, 5 x 10^5 TCID50 MV-CHIK or placebo on day 85 (Groups 2+5) and day 169 (Groups 3+6) following the first dose of vaccine.

Subjects may be on chronic or as needed (prn) medications if, in the opinion of the site principal investigator or appropriate sub-investigator, they pose no additional risk to subject safety or assessment of reactogenicity and immunogenicity. NOTE: Athletically trained subjects with a pulse > \= 45 - 49 may be enrolled if an ECG shows no evidence of first, second or third degree heart block.
5. Screening laboratory values must be within site normal limits, though trace urine protein is acceptable. Screening labs will include: Blood hemoglobin, White blood cell (WBC) count, Absolute neutrophil count, Platelets, Creatinine, Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), Bilirubin (total), Glucose (random, must be less than 140), Urine dipstick for protein and glucose (negative to trace protein are acceptable), Negative HIV 1/2 antibody/antigen test, Hepatitis B surface antigen (HBsAg), and Hepatitis C virus (HCV) antibody NOTE: Creatinine values lower than the normal range may be acceptable if the PI or a designated licensed clinician determines that these laboratory findings are not clinically significant. HIV and hepatitis C viral load PCR testing may be performed for individuals suspected of having indeterminate antibody/antigen testing (Sites will use the standard HIV testing protocol for their institution).

15. Received or plans to receive measles-containing vaccine within 3 months prior to enrollment or planned to receive through study day 29 following the second dose of vaccine. measles, mumps, rubella vaccine.
16. History of anaphylaxis or severe allergic reaction to vaccines or history of allergic reaction to any components in the MV-CHIK vaccine.
17. Received an experimental or investigational agent within 1 month before study injections or expectation to receive an experimental agent through 6 months following the last study injection. Vaccine, drug, biologic, device, blood product, or medication.
18. Any condition that would, in the opinion of the investigator, place the subject at an unacceptable injury risk, render him/her unable to meet the requirements of the protocol, or that may interfere with successful study completion.
19. A history of alcohol or drug abuse during the previous 3 years For example, daily excessive alcohol or marijuana use or frequent binge drinking as determined by the investigator.
