Phase 1 Clinical Trial of ID93+GLA-SE Vaccine in BCG-vaccinated Healthy Adolescent
- Conditions
- Tuberculosis
- Interventions
- Biological: ID93+GLA-SEBiological: Placebo
- Registration Number
- NCT03806699
- Lead Sponsor
- Quratis Inc.
- Brief Summary
The purpose of this study is to evaluate safety, immunogenicity of ID93+GLA-SE compared to placebo following three intramuscular (IM) injections on Days 0, 28 and 56 in BCG-vaccinated QFT-negative healthy adolescent. The healthy adolescent will all have had the childhood TB vaccine called BCG, and all of them must have a negative result for a blood test for exposure to the bacteria that cause TB (QuantiFERON-TB Gold Plus, or "QFT"). Study participants will be followed for 12 months after the last injection for safety reasons. Blood will be drawn for laboratory tests for safety and immunogenicity tests. The study hypothesis is that the vaccine is safe and immunogenic in this study population.
- Detailed Description
After signing a written informed consent to participate in the study(under the premise the legal representative also agree their children participate in the study), subjects will be screened by required assessments per protocol. Eligible subjects who meet the inclusion/exclusion criteria will be randomized in a 1:1:1 ratio to Group 1, Group 2 or Control Group, receiving either ID93+GLA-SE or saline placebo on Days 0, 28 and 56. The investigator will evaluate the safety, immunogenicity of the Investigational Product in the subjects through-out the study.
For safety assessment, subjects will be instructed to record any adverse events in the Subject diary after each vaccination. Subject's safety will be reported to the investigators after 7 days from each vaccination via site visit or a phone call. Solicited AEs will be collected up to 7 days after the final vaccination with the Investigational Product and unsolicited AEs will be collected up to 28 days after the final vaccination with the Investigational Product. For long-term safety assessment of the Investigational Product, serious adverse events and adverse events of special interest will be monitored up to 12 months after the final vaccination with the Investigational Product.
For immunogenicity assessment, blood samples will be collected and analyzed before and after each vaccination. QFT-Gold Plus testing will be performed after 1 month and 12 months from the final vaccination with the Investigational Product.

Group Intervention Description High dose ID93+GLA-SE ID93+GLA-SE Participants will receive 0.5 mL (10 μg ID93 + 5 μg GLA-SE) IM injection into deltoid area, three times in 4-week intervals on Days 0, 28, and 56. Control group Placebo Participants will receive 0.5 mL (physiological saline) IM injection into deltoid area, three times on 4-week intervals on Days 0, 28, and 56. Low dose ID93+GLA-SE ID93+GLA-SE Participants will receive 0.5 mL (2 μg ID93 + 5 μg GLA-SE) intramuscular injection (IM) into deltoid area, three times in 4-week intervals on Days 0, 28, and 56.
- Primary Outcome Measures
Name Time Method Adverse events Solicited AEs for 7 days following each injection, unsolicited AEs for 28 days after each injection, SAEs and AESIs for 12 months after the last injection. Solicited (local and systemic reactogenicity), unsolicited (all other adverse events, including laboratory assessments and vital signs), serious AEs and AEs of special interest.
- Secondary Outcome Measures
Name Time Method Humoral and cellular immunogenicity assays Days 0, 28, 56, 84, and 12 months after last injection. Immunogenicity will be evaluated by measuring humoral and cellular responses to ID93 + GLA-SE at specified timepoints
