Safety and Risk of Sensitisation of the rdESAT-6 + rCFP-10 Skin Test Following Repeated Intradermal Administration
Phase 1
Completed
- Conditions
- Tuberculosis
- Registration Number
- NCT00793702
- Lead Sponsor
- Statens Serum Institut
- 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.

- Has a C-reactive protein (CRP) level > 50 mg/L
- Has severe scarring, burn, rash, eczema, psoriasis, or any other skin disease at or near the injection site(s)
