A Study to Evaluate the Safety, Tolerability and Pharmacokinetics Profile of MT101-5 in Healthy Volunteers

A Phase I, Randomized, Double-Blind, Placebo-Controlled, Single Ascending Dose (SAD) Study Including a Food Interaction Study, Followed by a Multiple Ascending Dose (MAD) Study to Evaluate the Safety, Tolerability and Pharmacokinetics Profile of MT101-5 in Healthy Volunteers

The primary study objective is to establish the safety and tolerability of MT101-5 after a single and multiple dose administrations in healthy volunteers. The safety and overall tolerability of MT101-5 will be evaluated based on:

• Incidence of Dose Limiting Toxicities (DLTs)
• Incidence of Treatment-Emergent Adverse Events (TEAEs).
• Incidence of withdrawals due to Adverse Events (AEs).
• Change/shifts in laboratory values. Change in vital signs.
• Change in Electrocardiogram (ECG) parameters.
• Changes in physical examination findings

Study Overview

• Status: Completed
• Conditions: Parkinson's Disease
• Intervention / Treatment: Drug: MT101-5

Detailed Description

SAD Phase including Food Interaction:

Subjects will be assigned to one of up to five MT101-5 treatment cohorts and will be randomly assigned 6:2 within their cohort to receive MT101-5 or placebo. On Day 1, following an overnight fast of at least 10 hours, the randomly assigned dose of MT101-5 or placebo will be administered as oral tablet in a fasting state with 240 mL (i.e., 8 fluid ounces) of water. Additional water is permitted ad lib except for the period 1 hour before to 1 hour after administration of the drug product. No food is allowed for at least 4 hours after the dose. Subjects should receive standardized meals scheduled at the same time throughout the study.

For the Food Interaction phase, on Day 1 following an overnight fast of at least 10 hours, the study subjects should start their standardized high-fat breakfast meal 30 minutes before administration of the drug product. Trial subjects should eat this meal in 30 minutes or less. Subjects will be administered MT101-5 or placebo as an oral tablet 30 minutes after start of intake of a standardized high-fat breakfast with 240 mL (8 fluid ounces) of water. Additional water is allowed ad lib except for 1 hour before and 1 hour after drug administration. No food is allowed for at least 4 hours after the dose.

MAD Phase:

Subjects will be randomly assigned 6:2 to receive MT101-5 or placebo once daily for 7 days. On Day 1, following an overnight fast of at least 10 hours, the randomly assigned dose of MT101-5 or placebo will be administered as oral tablet in a fasting state with 240 mL (i.e., 8 fluid ounces) of water. Additional water is permitted ad lib except for the period 1 hour before to 1 hour after administration of the drug product. No food is allowed for at least 4 hours after the dose. Subjects should receive standardized meals scheduled at the same time throughout the study. The same will be followed for days 2-7.

Subjects will be assigned to 1 of up to 5 cohorts and will be randomized within each cohort to MT101-5 or placebo, as follows: cohort 1: 100 mg (8 subjects total; 6 receiving MT101-5, 2 receiving placebo); cohort 2: 150 mg (8 subjects total; 6 receiving MT101-5, 2 receiving placebo); cohort 3: 300 mg (8 subjects total; 6 receiving MT101-5, 2 receiving placebo); cohort 4: 450 mg (8 subjects total; 6 receiving MT101-5, 2 receiving placebo); cohort 5: 600 mg (8 subjects total; 6 receiving MT101-5, 2 receiving placebo)	Drug: MT101-5; Tablet
Experimental: Food Interaction Phase; Food Interaction Phase: Following the completion of the SAD phase, if study stopping criteria (SSC) is not met, then subjects in cohort 5 will cross-over to the fed part of the study following a 7 day washout period. If SSC is achieved in the SAD phase, then the previous dose will be in the Food Interaction phase.	Drug: MT101-5; Tablet
Experimental: MAD Phase; MAD Phase; Blinding and Randomization: This is a randomized, double-blind, placebo-controlled study in approximately 8 elderly healthy volunteers. If study stopping criteria (SSC) is not met in the SAD phase, then subjects will be assigned to the cohort 5 dose. If SSC is achieved in the SAD phase, then the previous dose will be used as the cohort in the MAD phase	Drug: MT101-5; Tablet
