Phase I Clinical Trial to Evaluate the Safety of Recombinant Mycobacterium Tuberculosis Fusion Protein (EEC) in Healthy Adults Aged 18-65 and Patients With Pulmonary Tuberculosis

NCT06224608 | Completed Phase 1

• 1 other identifier: KN-EEC-I
• Study Type: interventional
• Target: 60
• Locations: 1 country
• Sites: 2

Brief Summary

The study is to enroll 60 participants aged 18-65 years old, including 30 healthy subjects and 30 tuberculosis patients. Low-dose (2.5 μg/ml), medium-dose (5 μg/ml), and high-dose (10 μg/ml) studies will be conducted separately for healthy subjects and pulmonary tuberculosis patients, with 20 participants in each dosage group. Within 28 days after the skin test of the test drug, observations were made of reactions at the skin test site, reactions at non-skin test sites, concomitant medication, and any other physical discomfort (skin test site-specific reactions were recorded separately).

Outcome Measures

Primary Outcomes (4)

• Incidence of adverse events (AEs) at the skin test site and non-skin test site within 28 days after skin testing, with particular attention to the incidence of AEs within 7 days after skin testing.

  28 days after injection

• Incidence of abnormal blood routine, blood biochemistry, urine routine, and electrocardiogram detection indexes on the 3rd day after skin testing.

  3 days after injection

• Incidence of abnormal vital signs within 7 days after skin testing.

  7 days after injection

• Incidence of serious adverse events (SAEs) within 28 days after skin testing.

  28 days after injection

Secondary Outcomes (3)

• Specific skin reactions at the skin test site at 30 minutes, 2 hours, 4 , 8 , 24 , 48 , 72 , 96 hours, and 7 days after skin testing for different doses of EEC.

  7 days after injection

• Agreement between skin test results and IGRA test results for different doses of EEC.

  7 days after injection

• Agreement between IGRA test results before and after skin testing.

  7 days after injection
