ClinConnect Summary

This clinical trial is investigating how food affects the way a medication called Hezkue Turbo® (ASP-001.1, sildenafil) works in the body. Specifically, researchers want to see if taking this medication after eating is different from taking it on an empty stomach. The study will involve healthy adult men aged 20 to 70 years, who are in good health and meet specific criteria, such as having a certain body weight and not having serious health issues.

Participants in the study will need to agree to take part after being fully informed about what it involves. They can expect to follow certain guidelines, like avoiding specific foods and drinks before the trial, and they will undergo health checks to ensure they are suitable for the study. It’s important to note that this trial is not yet recruiting participants, so if someone is interested, they will need to wait until it opens for enrollment. Overall, this study aims to help understand the best way to use Hezkue Turbo® for treating erectile dysfunction.
