Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a phase 1 trial to evaluate the safety and pharmacokinetics of single and multiple ascending doses and effect of food on the pharmacokinetics of a novel antimalarial drug in healthy adults. The study will enroll 104 healthy volunteers, males and females, aged 18 to 45 years and will consists of 3 parts: Part 1, Single Ascending Dose (SAD); Part 2, Multiple Ascending Dose (MAD); and Part 3, Food Effect. Part 2 and Part 3 may be initiated after a Safety Monitoring Committee (SMC) review and approval of the of Part 1 safety data. Study duration will be 16 months with patient participation duration 14 days for SAD and Food Effect, and 18 days for MAD. The primary objectives of this study are to: 1) assess the safety and tolerability of single doses of DM1157 at levels ranging from 9 mg to 900 mg; 2) assess the safety and tolerability of DM1157 administered as single daily doses for 3 days at levels ranging from 150 mg to 900 mg; 3) assess the safety and tolerability of DM1157 administered with or without food.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a first-in-humans, phase 1, randomized, double-blind, single-site, placebo-controlled study in 104 healthy volunteers, males and females, aged 18 to 45 years inclusive. The study will consists of 3 parts: Part 1, Single Ascending Dose (SAD) - participants will be administered a single dose (ranges from 9 mg to 900 mg) of DM1157 orally after fasting or a matching placebo; Part 2, Multiple Ascending Dose (MAD) - participants will be administered three doses (ranges from 150 mg to 900 mg) of DM1157 orally once daily for three days after fasting or a matching placebo; and Part 3, Food Effect - participants will be administered 300 mg of DM1157 orally with high fat meal or a matching placebo. Part 2 and Part 3 may be initiated after a Safety Monitoring Committee (SMC) review and approval of the of Part 1 safety data. Study duration will be 16 months with patient participation duration 14 days for SAD and Food Effect, and 18 days for MAD. The primary objectives of this study are to: 1) assess the safety and tolerability of single doses of DM1157 at levels ranging from 9 mg to 900 mg; 2) assess the safety and tolerability of DM1157 administered as single daily doses for 3 days at levels ranging from 150 mg to 900 mg; 3) assess the safety and tolerability of DM1157 administered with or without food. The secondary objectives are to: 1) assess the PK of single doses of DM1157 at levels ranging from 9 mg to 900 mg, including dose proportionality; 2) assess the PK of DM1157 administered as single daily doses for 3 days at levels ranging from 150 mg to 900 mg; 3) assess the PK of 300 mg DM1157 administered with or without food, including determination of the presence or absence of a food effect on exposure.
