Outcome Measures

Primary Outcomes (6)

  • Number of Subjects Reporting Local Reactogenicity Signs and Symptoms Within 7 Days of Any Injection

    Subjects recorded the occurrence of solicited symptoms on a memory aid for 7 days after any injection and reviewed the memory aid with clinic staff at a follow up visit. Subjects are counted once for each symptom at the worst severity if they indicated experiencing the symptom at any severity during the reporting period. The number reported for "Any Local Symptom" is the number of subjects reporting any local symptom at the worst severity. Solicited reactogenicity was recorded without an attribution assessment. Grading (Mild, Moderate, Severe) was done using the Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials (FDA Guidance - September 2007).

    7 days after any injection

  • Number of Subjects Reporting Systemic Reactogenicity Signs and Symptoms Within 7 Days of Any Injection

    Subjects recorded the occurrence of solicited symptoms on a memory aid for 7 days after any injection and reviewed the memory aid with clinic staff at a follow up visit. Subjects are counted once for each symptom at the worst severity if they indicated experiencing the symptom at any severity during the reporting period. The number reported for "Any Systemic Symptom" is the number of subjects reporting any systemic symptom at the worst severity. Solicited reactogenicity was recorded without an attribution assessment. Grading (Mild, Moderate, Severe) was done using the Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials (FDA Guidance - September 2007).

    7 days after any injection

  • Number of Subjects With an Abnormal Laboratory Result

    Safety laboratory parameters included hematology (hemoglobin, hematocrit, platelets, red blood cell (RBC), white blood cell (WBC), neutrophil, monocyte, lymphocyte, basophil and eosinophil counts, mean corpuscular volume (MCV)) and chemistry (ALT). Complete blood count, differential, platelet and ALT results were collected at screening (≤ 56 days before enrollment), Day 0 prior to study product administration (baseline), and Days 28 and 56.

    4 weeks after last injection

  • Number of Subjects Reporting Unsolicited Adverse Events (AEs)

    Unsolicited AEs were reported from receipt of first study injection through 4 weeks after the last study injection administered. After the indicated time period through the last expected study visit at 72 weeks, only new chronic medical conditions and SAEs (reported as a separate outcome and in the AE module) were collected as unsolicited AEs. A subject with multiple experiences of the same event is counted once using the event of worst severity. The number reported for "Any AE" is the number of subjects reporting at least one or more AEs.

    Through study completion, an average of 72 weeks after first injection

  • Number of Subjects Reporting Serious Adverse Events (SAEs)

    SAEs were reported from receipt of first study injection through the last expected study visit at 72 weeks. Grading (Mild, Moderate, Severe, Life-threatening, and Death) was done using the Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials (FDA Guidance - September 2007). The relationship between a SAE and the study product was assessed by the investigator on the basis of his or her clinical judgment and the definitions outlined in the protocol. A subject with multiple SAEs is counted only once.

    Through study completion, an average of 72 weeks after first injection

  • Number of Subjects With Confirmed Chikungunya Virus (CHIKV) Infection Events

    Confirmed Chikungunya infections by positive polymerase chain reaction (PCR) results reported from receipt of first study injection through the last expected study visit at 72 weeks.

    Through study completion, an average of 72 weeks after first injection

Secondary Outcomes (3)

  • Chikungunya Antigen-specific Neutralizing Antibody Geometric Mean Titer (GMT) - Per Protocol Population

    Week 8

  • Chikungunya Antigen-specific Neutralizing Antibody Geometric Mean Titer (GMT) - Intent-to-Treat Population

    Week 8

  • Chikungunya Antigen-specific Neutralizing Antibody Geometric Mean Titer (GMT) - Modified Intent-to-Treat

    4 weeks after last study injection

Study Arms (2)

Group 1: VRC-CHKVLP059-00-VP 20 mcg

EXPERIMENTAL

Group 1 subjects were randomized to receive two intramuscular (IM) injections of CHIKV VLP vaccine (VRC-CHKVLP059-00-VP) at Day 0 and Day 28 (+14 days) at a dose of 20 micrograms (mcg).

Biological: VRC-CHKVLP059-00-VP

Group 2: Placebo (VRC-PBSPLA043-00-VP)

PLACEBO COMPARATOR

Group 2 subjects were randomized to receive two intramuscular (IM) injections of Phosphate Buffered Saline (VRC-PBSPLA043-00-VP) placebo at Day 0 and Day 28 (+14 days).

Other: VRC-PBSPLA043-00-VP

Interventions

VRC-CHKVLP059-00-VP is a virus-like particle (VLP) vaccine that consists of CHIKV VLP composed of E1, E2 and capsid proteins of the CHIKV (strain 37997).

Group 1: VRC-CHKVLP059-00-VP 20 mcg

VRC-PBSPLA043-00-VP, a sterile phosphate buffered saline (PBS) is the placebo for the CHIKV VLP vaccine.

Group 2: Placebo (VRC-PBSPLA043-00-VP)
