ClinConnect Summary

This clinical trial is studying a new medication called Leucettinib-21 to see how safe it is and how it works in the body. The trial has four parts: the first two parts involve healthy men aged 18 to 45, where they will receive different doses of the medication to assess safety and how the body processes it, including how food affects its absorption. The last two parts include individuals with Down Syndrome and Alzheimer's Disease, focusing on how well they tolerate a single dose of the medication.

To be eligible, participants need to be healthy males within a specific age range for the first three parts, and for the fourth part, men with Down Syndrome and Alzheimer's Disease can join. Participants can expect to undergo health assessments, including blood tests and heart monitoring, to ensure they are fit for the study. It’s important for potential participants to understand that they will need to follow specific health guidelines, and the study will require their informed consent before starting. Overall, this trial aims to help find new treatments for individuals with Down Syndrome and Alzheimer's Disease.
