This study aims to determine if ST-04, with or without sildenafil, will improve erectile function (EF) compared to baseline.\n\nParticipants in this study will receive ST-04, a new formulation containing the vasodilator, alprostadil which is known to be an effective drug in treating erectile dysfunction. ST-04 will be dispersed along the urethra, forming a hydrogel which adheres to the lining of the urethra with the goal of penile tumescence and erection. Participants may receive up to 3 dose level escalations of ST-04 over a 12-week period, for a total of up to 11 administrations of ST-04. Dose escalation may also be done with and without sildenafil.",[27,28,29],"Erectile Dysfunction (ED)","Erectile Dysfunctions","Erectile Function",[31,29,32,33],"Erectile Dysfunction","Alprostadil","Sildenafil","RECRUITING","2026-05-20",{"date":37,"type":38},"2026-05-22","ACTUAL",{"date":40,"type":21},"2026-05",{"date":42,"type":21},"2027-05",{"name":44,"class":45},"Ryan Flannigan, MD","OTHER",""]
