Using placental tissue to improve erectile recovery after prostate surgery

Patient-Reported Erectile Recovery and Quality of Life Outcomes With Lyopreserved Placental Tissue Applied Directly Over Neurovascular Bundle During Nerve-Sparing Radical Prostatectomy Versus Standard of Care

Phase 2 Interventional Johns Hopkins University · NCT05366842

This study is testing if using preserved placental tissue during prostate surgery can help men recover their ability to have erections and control urination better than regular care.

What this trial studies

This clinical trial investigates the effectiveness of applying lyopreserved placental tissue (LPT) over the neurovascular bundle during nerve-sparing robotic prostatectomy for prostate cancer. The study aims to determine if this intervention can enhance recovery of erectile function and urinary continence compared to standard care. Eligible participants are men aged 40 to 65 with localized prostate cancer and intact pre-surgical erectile function, who will be randomized to receive either the LPT treatment or standard care. The trial will measure outcomes using the Sexual Health Inventory for Men (SHIM) score post-surgery.

Who should consider this trial

Good fit: Ideal candidates are men aged 40 to 65 with localized prostate cancer and good preoperative erectile function.

Not a fit: Patients with a history of penile deformity, androgen therapy, or radiation therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve erectile function recovery and quality of life for men undergoing prostate cancer surgery.

How similar studies have performed: Other studies using placental tissue in surgical applications have shown promise, but this specific approach is novel.
