Clinical Trial Summary

This is a Single-center, Randomized, Double-blind, Placebo-controlled Phase I Study to Evaluate the Safety, Tolerability and PK Profiles of Single and Multiple Ascending Doses of Antimicrobial Peptide PL-18 Vaginal Suppositories.


Clinical Trial Description

Subjects who provide written informed consent to participate voluntarily in the clinical study will be screened. Eligible subjects will be sequentially enrolled into the above five sequential cohorts and randomized to receive PL-18 (cohort 1: n=8; cohort 2/3/4/5: n=6) or matching placebo (n=2). Subjects will be observed for 3 days after a single dose and receive PL-18 or placebo, once daily, for 6 consecutive days, if no grade ≥2 drug-related adverse events (AEs) occur. During the study, PK sample collection, physical examination, vital signs, laboratory tests, electrocardiography (ECG) and tolerance evaluation will be performed based on the protocol schedule. To ensure the safety of the subjects, two sentinel subjects will be enrolled first in each cohort; one subject will be randomized to receive PL-18, and the other subject randomized to receive placebo. The safety data of the two sentinel subjects from initiation of single dosing to the last drug administration of multiple dosing on D11 will be reviewed by the investigator and sponsor before the subsequent subjects in that dose cohort are enrolled. Subsequent subjects could be simultaneously enrolled, with one randomized to receive placebo and others randomized to receive PL-18. ;
