Clinical Trial of Naoqingzhiming Tablets in Healthy Chinese Subjects

The single-dose trial plan enrolls 52 Chinese healthy subjects. Qualified subjects will enter 6 dose groups in order from low to high: 180mg, 360mg, 720mg, 1080mg, 1620mg and 2160mg, with increasing dose design The first group (180mg) is a pre-test. Two subjects were selected and all received the test drug. They were observed for 24 hours after a single dose for safety assessment, and followed up 7-10 days after leaving the group or early withdrawal. If more than one subject has an adverse event that meets CTCAE V5.0 Grade II or above and is judged to be related to the test drug, then consider reducing the dose, otherwise proceed to the next dose group trial. Groups 2, 3, 4, 5, and 6 follow the "8+2 principle", with 10 subjects in each group, 8 receive the test drug, and 2 receive the placebo. Observe for 24 hours after a single dose for safety assessment , And follow up 7-10 days after leaving the group or early withdrawal. Each subject received only one dose group of the trial, only one study drug (experimental drug or placebo), and no longer participated in the other dose group trials or took two study drugs. During the dose escalation process, after completing the safety assessment of the previous dose group, if the dose escalation suspension standard is not met, continue the test of the lower-dose group. It is not allowed to conduct the test of 2 or more dose groups at the same time. In the above six groups of trials, it is not only necessary to observe the safety and tolerability of the subjects taking the study drug, but also to evaluate the pharmacokinetic characteristics of a single dose.

According to the results of animal pharmacokinetic studies, the dose grouping for the multiple-dose study is tentatively set to 2 groups: 360mg group and 720mg group.

The multiple-dose study plan recruited 24 Chinese healthy subjects, following the "10+2 principle", each group of 12 subjects, 10 cases received the test drug, 2 cases received placebo, 3 times a day, continuous medication On 14 days, continue to observe for 24 hours after the last administration for safety assessment, and follow up 7-10 days after leaving the group or early withdrawal. In the process of continuous medication, if 3/10 and more than 3/10 of the subjects in a dose group who received the test drug withdraw from the trial due to adverse events related to the test drug, the trial should be aborted; after completing the first group, it is safe After the sexual assessment, if the suspension criteria are not met, the second group of trials will continue. Each subject only participates in one group of trials and only receives one study drug (experimental drug or placebo), and no longer participates in other group trials or takes two study drugs. In the above two groups of trials, it is not only necessary to observe the safety and tolerability of multiple administrations, but also to evaluate the pharmacokinetic characteristics of multiple administrations.
