Safety, Pharmacokinetics, and Food Effect of PS1 in Subjects

Pharmasaga Co. Ltd.75 enrolled

Overview

This is a phase I, double-blind, placebo-controlled, randomized, single- and multiple-ascending dose study to evaluate new study intervention, PS1. PS1 is a potential blood glucose control medication, which is developed by Pharmasaga Co. Ltd. planned for treating type II diabetes mellitus (T2DM). This is a first-in-human study to evaluate the safety, tolerability, pharmacokinetics (PK), food effect and potential efficacy of PS1 in subjects.

This first-in-human Phase I study consists of a single ascending-dose (SAD) portion, a food effect (FE) portion, and a multiple ascending-dose (MAD) portion, aiming to evaluate the safety, tolerability, pharmacokinetics, food effect and potential efficacy of PS1 in healthy subjects. A randomized, double-blinded, placebo-controlled study design will be applied for the SAD portion for healthy subjects with three SAD dose cohorts-25 mg (Cohort 1), 50 mg (Cohort 2), and 75 mg (Cohort 3). An eligible subject will receive a single dose of PS1 or Placebo tablets (8 subjects in each cohort, 6 PS1 + 2 Placebo) in a fed condition on Day 1 and be followed for 7 days. In FE portion, only one cohort (Cohort 4) is assigned. The FE cohort (Cohort 4) will use the same study design (randomized, double-blinded, placebo-controlled, 6 PS1 + 2 Placebo) as the SAD cohorts. An eligible subject will receive a single dose of 50 mg PS1 or Placebo tablets in a fasted condition on Day 1 and be followed for 7 days. SAD portion for T2DM patients: An open-labeled study design will be applied for the SAD portion for T2DM patients with two SAD dose cohorts-25 mg (Cohort A) and 50 mg (Cohort B). An eligible T2DM patients will receive a single dose of PS1 tablets (6 subjects in each cohort) in a fed condition on Day 1 and be followed for 14 days. Subjects in this portion will have safety and PK observation but will not be evaluated for DLT. MAD portion for T2DM patients: After confirming the safety and pharmacokinetics of all SAD cohorts (Cohorts 1, 2, 3, A, and B) and the FE cohort (Cohort 4) by iSMC and approved by the authority, a randomized, double-blinded, placebo-controlled study design will be applied for the MAD portion for T2DM patients with two MAD dose cohorts-25 mg/day (Cohort 7) and 50 mg/day (Cohort 8). An eligible subject will receive PS1 or Placebo (8 subjects in each cohort, in a 6:2 ratio of PS1: Placebo) tablets once daily in a fed condition. The treatment period is 28±1 days. All subjects will be followed for additional 7 days.

Patients taking medications for T2DM comorbidities, i.e., hypertriglyceridemia, hyperlipidemia, and hypertension, should be on a stable dose of their medication for at least 3 months prior to Screening. Any other chronic medications should be on a stable dose for at least 4 weeks prior to Screening. Exclusion Criteria: Any subject meeting any of the following exclusion criteria will be excluded from study participation. 1. History of Type I diabetes mellitus 2.

Outcomes

Primary Outcomes

Incidence of dose-limiting toxicity (DLT) during the DLT observation period and the maximum tolerated dose (MTD) of PS1

Dose escalation will be terminated based on the following criteria: \- Among the six subjects who received PS1 in a cohort, more than one subject experienced DLT(s). MTD will basically be declared as the highest dose level at which ≤1/6 of PS1-treated subjects in a cohort experienced DLT(s). DLT is defined as 1. any adverse event (AE) ≥ Grade 3 (CTCAE v5.0)\* or 2. Grade 2 AE that does not resolve to grade 1 or less within 3 days\* \* Note: For Cohorts 7 and 8, AEs requiring specific definitions will be referenced under the heading 'For MAD cohorts (Cohorts 7 and 8)' below, while the remaining AEs will be followed the standard procedures outlined herein. that occurs in the DLT observation period and is causally related (possibly, probably, or definitely related) to the test article judged by the investigator.
