NCT03806686 | Unknown Phase 2 FDA Drug

• 1 other identifier: CT-QTP101-001
• Study Type: interventional
• Target: 107
• Locations: 1 country
• Sites: 3

Brief Summary

The purpose of this study is to evaluate the experimental tuberculosis (TB) vaccine called ID93+GLA-SE. The safety, immunogenicity, and efficacy of ID93+GLA-SE will be compared to placebo, after three intramuscular (IM) injections one month apart in healthy healthcare workers. The healthcare workers 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, immunogenicity, and efficacy tests. Efficacy will be evaluated by further QFT testing. The study hypothesis is that the vaccine is safe, immunogenic, and effective in this study population.

Control group

PLACEBO COMPARATOR

Participants will receive 0.5 mL Placebo (physiological saline) IM injection into deltoid area, three times on 4-week intervals on Days 0, 28, and 56.

Biological: Placebo

Interventions

Placebo BIOLOGICAL

Sterile normal saline

Control group

ID93+GLA-SE BIOLOGICAL

ID93 is a recombinant protein antigen comprising 4 antigens from Mycobacterium tuberculosis (Mtb). The adjuvant GLA-SE is a TLR4 agonist in a stable oil-in-water emulsion.

High dose ID93+GLA-SE; Low dose ID93+GLA-SE

Eligibility Criteria

• Age: 19 Years - 64 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• Male or female who is ≥19 and \<65 years of age.
• Healthcare workers who are QuantiFERON®-TB Gold Plus negative (not latently infected with Mtb) at screening.
• Able to comply with the scheduled visits, and are expected to continue working in the current medical institution and be available for a continuous follow-up by the investigator via provided contact information.
• Only for female subjects of childbearing potential:
• Must be HCG-negative from serum or urine pregnancy test, at screening;
• Agreed to use one of the following acceptable birth control methods to avoid pregnancy until the end of study (Visit 9): hormonal contraceptives, intrauterine device (IUD) or intrauterine system (IUS), tubal ligation, or combination of barrier methods (combined use of barrier methods such as male condoms, female condoms, cervical cap, diaphragm, sponge, or implant).
• History of BCG vaccination that is confirmed through medical examination (i.e., asking a subject about his/her condition) or presence of a scar.
• Body mass index (BMI) ≥19 and ≤33 (kg/m\^2) at screening
• Subjects who understand the study procedures, and voluntarily decide to participate in the study and sign the informed consent form..

You may not qualify if:

• History of positive tuberculin skin test or positive QuantiFERON®-TB results.
• History of severe chronic disease that may compromise the safety of the subject during the study (e.g., impairment of pulmonary function from tuberculosis infection or other pulmonary disease; chronic illness with signs of cardiac or renal failure; suspected progressive neurological disease or uncontrolled epilepsy).
• Body temperature ≥ 38℃ at the time of randomization or within 24 hours before randomization, from acute fever, acute respiratory diseases, or active infection.
• Malignant tumors or a history of malignant tumors.
• Plans to have surgery during the study period.
• Impaired immune functions including autoimmune disease or immunodeficiency disease.
• History of Guillain-Barre syndrome.
• Subjects with a history of anaphylaxis or severe allergic reaction to vaccines, eggs, or other allergens.
• Subjects living with a household member who has active TB or infectious TB.
• Clinically significant abnormal laboratory values for any of the following tests conducted in the study center, prior to randomization:
• Hemoglobin, hematocrit, absolute neutrophil count, absolute lymphocyte count, or platelet count: \< LLN (lower limit of normal)
• White blood cell count: \>ULN (upper limit of normal) or \<LLN (lower limit of normal) (i.e., must be within normal limits)
• ALT, AST, total bilirubin, alkaline phosphatase, creatinine, or blood urea nitrogen (BUN): \>ULN (upper limit of normal)
• Received an immunosuppressant, immunity-modifying drug, or other treatment that may affect the immune system including cytotoxic anti-cancer agents or radiotherapy, within 3 months before the randomization.
• Use of systemic steroids (equivalent to daily prednisone ≥ 15mg/day for more than 14 days), inhaled or intranasal steroids, within 3 months before randomization; however, use of topical corticosteroids are acceptable, regardless of dose.

Study Design

• Study Type: interventional
• Phase: phase 2
• Allocation: RANDOMIZED
• Masking: QUADRUPLE
• Who Masked: PARTICIPANT, CARE PROVIDER, INVESTIGATOR, OUTCOMES ASSESSOR
• Masking Details: Since the vials of ID93+GLA-SE and placebo control (normal saline) and their appearances after preparation are different, for double-blinding of the study, the study nurse who administers the study drug or the study pharmacist who stores and manages the study drug will be unblinded to maintain the quality of study blinding. Additionally, an unblinded study monitor will be responsible for confirming the quantity and release of the study drugs. Unblinded study personnels and unblinded study monitor should only be involved in the duties related to administration and/or recording of the study drug, and must not be involved in other duties that may break double-blinding of the study.
• Purpose: PREVENTION
• Intervention Model: PARALLEL
• Sponsor Type: INDUSTRY
• Responsible Party: SPONSOR

Model Details: Participants will be assigned to one of three groups: Low dose ID93+GLA-SE, High dose ID93+GLA-SE, or Control Group.
