Safety, Tolerability, and Immunogenicity of the Vaccine Candidates ID93 + AP10-602 and ID93 + GLA-SE Administered Intramuscularly in Healthy Adult Subjects

Completed · Phase 1

Conditions studied: Tuberculosis

In brief

This is a phase I randomized, double blind clinical trial designed to evaluate the safety, tolerability and immunogenicity of the ID93 recombinant protein antigen alone or formulated with GLA-SE or AP10-602 adjuvant in 70 healthy adults 18-49 years of age. Subjects will receive a total of 3 doses administered intramuscularly on Days 1, 29 and 57. Subjects will be monitored for approximately 422 days (365 days following the third study injection), including safety laboratory analyses done just prior to and 7 days following each study injection. Blood samples will be obtained for immunological assays (Luminex, intracellular cytokine staining at Days 1 and 71, and antibody analysis at Days 1 and 85). The primary objective is to evaluate the safety and tolerability of 10 µg ID93 + 5 or 10 µg AP10-602 compared to 10 µg ID93 + 5 µg GLA-SE and 10 µg ID93 alone following three consecutive intramuscular injections administered on Days 1, 29 and 57.

Who can join

Age: 18 and older, up to 49. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Males and nonpregnant females between the ages of 18 and 49 years, inclusive. 2. Women of childbearing potential* must agree to practice adequate contraception** for the 28-day period before Day 0 through 90 days after the third study injection. * A woman is considered of childbearing potential unless surgically sterile (tubal ligation, bilateral oophorectomy, or hysterectomy) or post-menopausal (>/=1 year). **Acceptable birth control methods include but are not limited to: abstinence from sexual intercourse with men; monogamous relationship with a vasectomized partner; barrier methods (condoms, diaphragms, spermicides, and intrauterine devices); and licensed hormonal methods. 3. In good health, as judged by the investigator and determined by vital signs*, medical history, and a targeted physical examination. * Temperature <38°C, heart rate </=100 bpm and >54 bpm, systolic blood pressure </=140 mmHg and >89 mmHg, diastolic blood pressure </=90 mmHg and >/=60 mmHg. NOTE: Athletically trained subjects with a pulse >/=45 may be enrolled at the discretion of the principal investigator or designated licensed clinical investigator. 4. Screening laboratory values must be within site normal limits, though trace urine protein is acceptable. -Blood hemoglobin -White blood cell (WBC) count -Neutrophil count -Platelets -Creatinine -AST -ALT -Bilirubin (total) -Glucose (random, must be less than 140) -Urine dipstick for protein and glucose (negative to trace protein are acceptable) -Negative Quantiferon-TB Gold test -Negative HIV 1/2 antibody, (HBsAg), and Hepatitis C virus (HCV) antibody NOTE: See Appendix D for site normal values. 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 testing. For African American participants, a WBC of >/= 3.5 k/mm\^3 is acceptable. 5. Able to understand and comply with planned study procedures and willing to be available for all study-required procedures, visits and calls for the duration of the study. 6. Provide written informed consent before initiation of any study procedures. 7. Willing to abstain from donating whole blood or blood derivatives until 90 days after the final study injection.

You may not qualify if…

• History of treatment for active or latent tuberculosis infection or history of positive PPD. 2. History or evidence of active tuberculosis. 3. Has received vaccination or immunotherapy with a BCG product at any time prior to randomization. 4. Shared a residence within the last year prior to randomization with an individual on anti-tuberculosis treatment or with culture or smear positive tuberculosis. 5. Received a tuberculin skin test within 3 months (90 days) prior to the time of randomization through study day 85. 6. Body temperature >/=100.4°F (>/=38°C) or acute illness within 3 days before study injection days (subject may be rescheduled). 7. A positive serum* or urine pregnancy test at screening or within 24 hours prior to study injection**, women who are planning to become pregnant***, or women who are breastfeeding. * At screening visit only ** If female of childbearing potential as defined in Inclusion Criterion #2 ***from 28 days prior to entering the study until 90 days after the final study injection 8. Immunosuppression as a result of an underlying illness or treatment or use of anticancer chemotherapy or radiation therapy (cytotoxic) within the preceding 36 months. 9. An active neoplastic disease* (excluding nonmelanoma skin cancer) or a history of any hematologic malignancy. * defined as neoplastic disease or treatment for neoplastic disease within the past 5 years 10. A history of autoimmune disease (systemic lupus, rheumatoid arthritis, scleroderma, polyarteritis, thyroiditis, etc). 11. Used an immunosuppressive or immunomodulatory drug* for 2 or more consecutive weeks within 6 months prior to the first study injection (nasal and topical steroids are allowed). *such as >0.5 mg/kg/day or >/=20 mg total dose/day of prednisone orally or >800 µg of inhaled beclomethasone 12. A diagnosis of schizophrenia, bipolar disease, or history of hospitalization for a psychiatric condition or previous suicide attempt. 13. A history of treatment for any other psychiatric disorder in the past 3 years that increases the risk to the subject in the opinion of the investigator. 14.

Received or plan to receive any live licensed vaccines within 4 weeks or inactivated licensed vaccines within 2 weeks of any study injection. 16.
