Official title: An Open Phase I Clinical Trial on the Safety and Risk of Sensitisation by Escalating Doses and Repeated Injections of the rdESAT-6 + rCFP-10 Skin Test Reagent Following Intradermal Administration to Healthy Adults
Study type: INTERVENTIONAL
Overall status: COMPLETED
Phase: PHASE1
Conditions: Tuberculosis
Keywords: tuberculosis
diagnosis
ESAT-6
CFP-10

Skin test for the diagnosis of tuberculosis infection
Lead sponsor: Statens Serum Institut
Sponsor class: OTHER
First posted: 2008-11-19
Enrollment: 42
Sex: ALL
Minimum age (years): 18
Maximum age (years): 55
Standard ages: ADULT
Accepts healthy volunteers: yes
Allocation: NON_RANDOMIZED
Intervention model: PARALLEL
Primary purpose: DIAGNOSTIC

Brief summary: The primary objective is to assess the safety of three dose levels (0.01, 0.1 and 1.0 µg) of the rdESAT-6 + rCFP-10 skin test reagent when injected into healthy adults. The secondary objective is to assess the risk of sensitisation of 0.01 and 0.1 µg rdESAT-6 + rCFP-10 when injected twice with time intervals of 6 or 12 weeks to healthy adults.


Eligibility criteria: Inclusion Criteria:

Exclusion Criteria:

1. Has a history of tuberculosis or has had a known contact to a person with active tuberculosis
2. Has a positive QuantiFERON-TB Gold In Tube test result at inclusion
3. Laboratory parameters outside of normal range judged by principal investigator to be clinically significant and/or abnormal glucose or protein levels in a urine sample at inclusion
4. Has been in treatment with a product which is likely to modify the immune response within 3 months prior to the day of inclusion (e.g., immunoglobulin, systemic corticosteroids, methotrexate, azathioprine, cyclosporine, infliximab or blood products)
5. Has been vaccinated with a live vaccine within 6 months prior to the day of inclusion (e.g., MMR, yellow fever, or oral typhoid vaccines)

11. Has severe scarring, burn, rash, eczema, psoriasis, or any other skin disease at or near the injection site(s)
12. Has a condition in which repeated blood drawings pose more than minimal risk for the volunteer, such as haemophilia, other coagulation disorders, or significantly impaired venous access
13. Is actively participating in another clinical trial or has participated in previous clinical trials investigating the rdESAT-6 skin test reagent
14. Is pregnant according to urine pregnancy test at inclusion
15. Is a female not willing to use contraceptives or is breastfeeding
16. Has a condition which in the opinion of the investigator is not suitable for participation in the study
