COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
This will be a randomized, double-blind, placebo-controlled, dose-escalation study of 3 dose
levels of LMN-101. Healthy volunteers will take LMN-101 or placebo orally either as a single
dose or at one of three dose levels three times daily over 28 days. Protocol-specified
evaluations and procedures will be performed on Days 1-2 and every one-two weeks during
dosing. Study observation will continue until 4 weeks after the last dose of study drug.
