简要总结
The purpose of this pilot study is to optimize a planned randomized, double-blind, placebo-controlled clinical trial evaluating the effects of Platelet-Rich Plasma (PRP) intralesional injections in men affected by Peyronie's disease (PD) in the fibrotic phase. The pilot study aims to identify potential challenges in the practical execution of the clinical trial, particularly regarding PRP preparation and the blinding process. Furthermore, it seeks to evaluate the effects of PRP injections.
详细描述
The study protocol is structured such that participants, after being informed about the project and providing consent, will attend a baseline visit where relevant data will be collected from the participant, questionnaires, the patient's medical record, and through an objective examination. Subsequently, participants will attend weekly injection sessions for 6 weeks, during which they will receive 3 PRP injections and 3 saline injections (placebo) in a randomized order. Three months after the final injection, participants will attend a follow-up visit, where the final data will be collected. Analysis will then be conducted.

研究组 & 干预措施
Platelet Rich Plasma (PRP)
Each participant will receive 3 PRP injections over the 6-week period, with weekly injections in a randomized sequence. The RedCap randomization module will ensure that each participant receives 3 injections of each type.
干预措施: Autologous Platelet Rich Plasma (Other)
Saline Solution (Placebo)
Each participant will receive 3 saline injections over the 6-week period, with weekly injections in a randomized sequence. The RedCap randomization module will ensure that each participant receives 3 injections of each type.
In addition, Platelet-Rich Plasma (PRP) will be prepared but, instead of being injected, it will be analyzed for platelet count.
干预措施: Saline solution (Other)
结局指标
主要结局
Platelet Concentration in the PRP
时间窗: The 6 week intervention period.
In the placebo sessions, the Platelet-Rich Plasma (PRP) sample (prepared using the Magellan Autologous Platelet Separator) will be sent for analysis of platelet concentration levels to ensure the quality of the PRP.
Evaluation of the Blinding Process
时间窗: The 6 week intervention period.
After each injection, both the administering physician and the participant will be asked to state whether they believe the injection contained PRP or saline. They will also be asked to justify their response, which will allow for adjustments to the practical implementation of the blinding process in the Randomized Controlled Trial (RCT), if necessary.
次要结局
- Changes in Plaque Size(From enrollment to 3 months post intervention.)
- Adverse Events(From the first injection to the 3 months post intervention follow-up.)
- Degree Changes in Penile Curvature.(From enrollment to 3 months post intervention.)
- Changes in the Peyronie's Disease Questionnaire (PDQ)(From enrollment to 3 months post intervention.)
- Changes in the Erection Hardness Score (EHS)(From enrollment to 3 months post intervention.)
- Changes in the Major Depression Inventory (MDI)(From enrollment to 3 months post intervention.)
- The Ability to Engage in Sexual Intercourse (question)(From enrollment to 3 months post intervention.)
- Preference for Surgical Intervention (question)(From enrollment to 3 months post intervention.)
- Satisfaction(From enrollment to 3 months post intervention.)
