Phase I Clinical Human Tolerability Study of Recombinant Mycobacterium Tuberculosis Allergen ESAT6-CFP10

Summary

In the tests, small sample of clinical study about Recombinant Mycobacterium Tuberculosis Allergen ESAT6-CFP10 ( Recombination EC Allergen） healthy adults was carried out. 24 healthy adults were included as study objects, they were randomly divided into four groups of different Recombinant Allergen EC dose (1, 5, 10μg/mL, maximum tolerated dose 20μg/mL, 6 person/dose) for single arm intradermal injection. The main examination items :vital signs (breathing, heart rate, blood pressure, body temperature ) of each volunteer at 15min, 30min, 1h, 2h, 4h, 8h, 24h, 48h, 72h, 96h after injection, skin reactivity (redness and/or induration) diameter of injection sites,local reaction ( rash, pain, itching, and skin and mucous membranes ) ,a variety of adverse events,routine blood,routine urine, liver and kidney function, ECG and chest X-ray films before and 7 days after intradermal injection . Preliminary evaluation of safety and tolerability of Recombinant Allergen EC applied in humans, which can provide a safe dosage range for phase II clinical study.
