Clinical Study of BCG Vaccine for Intradermal Injection
Randomized, Blinded, Placebo-Controlled Phase I Clinical Trial to Evaluate the Safety and Tolerability of BCG Vaccine for Intradermal Injection in 6-65 Year Olds
The study used a randomized, dose-escalation, blinded, placebo-controlled trial design.
In this trial, 160 subjects were enrolled. The test vaccines are divided into four dose groups: dose group 1 (0.025mg / 0.1ml / person), dose group 2 (0.05mg / 0.1ml / person), dose group 3 (0.075mg / 0.1ml / person), dose group 4 (0.1mg / 0.1ml / person), each Each dose group was enrolled according to 18-45、 46-65 、6-10、11-17years old .
The 4 doses are in descending order in the order of 18-45, 46-65, 11-17, and 6-10 years old. Each age group in the same dose group was enrolled in 8 experimental BCG subjects and 2 placebo subjects.
Among subjects aged 6-65 years, the dose group 2 study will be carried out after the safety assessment 14 days after the dose group 1 vaccination, and the dose group 3 study will be carried out after completing the safety assessment 14 days after the dose group 2 vaccination. Dose group 3 studies were carried out after safety assessment 14 days after vaccination. Within the same dose group, after completing the safety assessment 14 days after vaccination for the previous age group, vaccination for the next age group is carried out.

Detailed Description
The study used a randomized, dose-escalation, blinded, placebo-controlled trial design.
In this trial, 160 subjects were enrolled. The test vaccines are divided into four dose groups: dose group 1 (0.025mg / 0.1ml / person), dose group 2 (0.05mg / 0.1ml / person), dose group 3 (0.075mg / 0.1ml / person), dose group 4 (0.1mg / 0.1ml / person), each Each dose group was enrolled according to 18-45、 46-65 、6-10、11-17years old .
The 4 doses are in descending order in the order of 18-45, 46-65, 11-17, and 6-10 years old. Each age group in the same dose group was enrolled in 8 experimental BCG subjects and 2 placebo subjects.
Among subjects aged 6-65 years, the dose group 2 study will be carried out after the safety assessment 14 days after the dose group 1 vaccination, and the dose group 3 study will be carried out after completing the safety assessment 14 days after the dose group 2 vaccination. Dose group 3 studies were carried out after safety assessment 14 days after vaccination. Within the same dose group, after completing the safety assessment 14 days after vaccination for the previous age group, vaccination for the next age group is carried out.
BCG-PPD and EC skin test were performed during the screening period, and the skin test results were followed up at 48 hours; blood routine, urine routine, blood biochemistry, HIV antibody test, electrocardiogram, chest X-ray examination, physical examination, vital signs (heart rate, blood pressure) And body temperature), female subjects of childbearing age undergo a blood pregnancy test. Those eligible for entry will receive a dose of the trial vaccine or placebo on the same day (day 0); Observe vital signs (heart rate, blood pressure and body temperature), reactions at the inoculation site, and reactions at the non-inoculation site at 30 minutes, 7 days, and 14 days after vaccination; Blood routine, urine routine, blood biochemistry, electrocardiogram examination on the 14th day after vaccination; BCG-PPD and EC skin tests were performed on the 84th and 180th days after inoculation.
If the blood routine, urine routine, blood biochemistry, electrocardiogram examinations after vaccination are abnormal and have clinically meaningful results, a re-test is required. Under special circumstances, the number of re-tests can be appropriately increased until the follow-up outcome.
