ClinConnect Summary
This clinical trial is studying the long-term safety and effectiveness of a new tablet called TPN171H for treating erectile dysfunction (ED) in men. The trial is currently recruiting male participants aged between 18 and 75 who have experienced ED for at least three months. To be eligible, participants should be in a stable heterosexual relationship and have faced difficulties in achieving successful sexual intercourse. They should be willing to make at least four attempts at sexual intercourse each month and comply with study requirements, such as taking the medication as directed and attending scheduled visits.
Participants in the trial can expect to take the TPN171H tablet over an extended period while being monitored by healthcare professionals. They will need to share their experiences and results in a diary throughout the study. It's important to note that certain individuals, such as those with specific health conditions or who have had certain surgeries, may not qualify for this trial. Overall, this study aims to better understand how safe and effective TPN171H is for men struggling with erectile dysfunction.
