Phase I Study of PH100 (Ecklonia Cava Phlorotannins)

Safety Issues Clinical Trial

Official title: A Double-Blind, Placebo-Controlled, Single Ascending Dose Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of PH100 Capsules in Healthy Adult Volunteers

Status Completed

Clinical Trial Summary

The purpose of this study was to determine the safety and tolerability of PH100, a purified phlorotannins from a brown alga Ecklonia cava and the pharmacokinetics of its major compounds 8,8'-bieckol, dieckol, and phlorofucofuroeckol A (PFF-A), after single, ascending, oral doses of PH100 Capsules (over-encapsulated tablets) in healthy adult volunteers.

Clinical Trial Description

This was a single-center, randomized, double-blind, placebo-controlled, single ascending dose study in healthy volunteers in which subjects received either placebo or a 100 mg, 200 mg, 400 mg, 800 mg, 1200 mg, or 1600 mg dose of PH100 capsules (over-encapsulated tablets containing purified Ecklonia cava phlorotannins as an active ingredient) in escalating dose groups (six cohorts). A total of 48 subjects were enrolled. Each cohort comprised eight subjects. Within each cohort, six subjects received PH100 and two subjects received placebo. The first cohort was dosed as a single group with PH100 (100 mg) or placebo. The subsequent five cohorts were dosed sequentially with 200 mg, 400 mg, 800 mg, 1200 mg, and 1600 mg of PH100 or placebo. Safety and pharmacokinetic data were collected and evaluated following each cohort. Dose escalation occurred after review of the safety and pharmacokinetic data from the preceding cohort(s). Doses were administered with subjects in the fasted condition. ;
