Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 60 years
  • All sexes
  • No healthy volunteers
  • Adult

Who may be able to join

  • Males and females 18 to 60 years of age.
  • Subjects must have been successfully treated, i.e., completed the scheduled course of TB treatment as per the prevailing South African national guidelines, for MTB culture-confirmed, drug sensitive pulmonary TB, as evidenced by a record of positive liquid MTB culture with formal drug sensitivity testing (DST) and/or by Xpert MTB/RIF test at baseline.
  • Must have two separate samples showing bacteriologic confirmation of cure - defined in the first instance as Xpert MTB/RIF test negative, or, if Xpert MTB/RIF positive, as MTB liquid culture negative - on two successive occasions at least 30 days apart. Subjects who are sputum unproductive will be deemed Xpert MTB/RIF and MTB liquid culture negative.
  • Female subjects of childbearing potential must have a negative serum pregnancy test at screening and a negative urine pregnancy test on the day of each study injection, must not be breast-feeding, and be willing to avoid pregnancy for 3 months following first study injection. Women physically capable of pregnancy (not sterilized and still menstruating or within 1 year of the last menses if menopausal) in sexual relationships with men must use an acceptable method of avoiding pregnancy during this period. Acceptable methods of avoiding pregnancy include a sterile sexual partner, sexual abstinence (not engaging in sexual intercourse), hormonal contraceptives (oral, injection, transdermal patch, or implant), vaginal ring, intrauterine device (IUD), or the combination of a condom or diaphragm with spermicide gel.
  • The following screening laboratory values must be within the laboratory reference range or, if abnormal, deemed not clinically significant and less than Grade 2 severity on the FDA Toxicity Scale, as determined by the PI and LMM or Sponsor Medical Advisor: ALT, AST, total bilirubin, creatinine, total WBC count, hemoglobin, and platelet count.
  • The HIV 1/2 antibody serology tests must be negative.
  • Must give informed consent, be able and willing to make all evaluation visits, be reachable by telephone or personal contact by the study site personnel, and be willing to remain in the study area for the duration of the trial.

Who cannot join

  • TB treatment failure, as evidenced by clinical diagnosis or a positive MTB liquid culture at month 4 or 5 after starting treatment. A positive MTB liquid culture at, or after, end of treatment would exclude subjects from receiving further study injections.
  • Previous course of TB treatment completed within 5 calendar years prior to obtaining baseline diagnostic sputum samples.
  • Receipt of any investigational products or investigational drug in the past 6 months or investigational vaccine ever.
  • Treatment with immunosuppressive drugs (e.g., oral or injected steroids, such as prednisone; high dose inhaled steroids) in the past 6 months. Topical steroids would be allowable.
  • Received incomplete or investigational, or non-standard TB drug regimen, other than the prevailing current South African national guideline as reference standard, or poor adherence to TB treatment regimen.
  • Diagnosed with rifampicin-resistant MTB strain (by Xpert MTB/RIF and/or culture and formal DST).
Show all 10Show fewer
  • History of autoimmune disease or other causes of immunosuppressive states.
  • History or evidence of any acute or chronic illness (including diabetes mellitus, asthma), medical or surgical condition, or chronic heavy ethanol or drug use, or use of medication that, in the opinion of the Principal Investigator, may interfere with the evaluation of the safety or immunogenicity of the vaccine.
  • Subjects with a history of previous anaphylaxis or severe allergic reaction to vaccines, eggs, or unknown allergens.
  • Subjects who are unlikely to cooperate with the requirements of the study protocol.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Adverse Events

    Safety outcomes will include solicited adverse events within 7 days and unsolicited adverse events within 28 days after each study injection; and serious adverse events after the first study injection until end of study follow-up.

    Measured: 224 days

Secondary outcomes (1)
  1. Immunogenicity Responder Rate

    Immunogenicity will be evaluated by measuring humoral and cellular responses to ID93 + GLA-SE at Day 70.

    Measured: Day 70

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ID93 + GLA-SE in people with Pulmonary Tuberculosis, run by Access to Advanced Health Institute (AAHI) at 3 sites in South Africa.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in South Africa. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 9 Nov 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Adverse Events (time frame: 224 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02465216, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Mar 2019.
