taVNS for relieving symptoms of moderate-to-severe chronic prostatitis/CPPS

Effect of Transcutaneous Auricular Vagus Nerve Stimulation on Moderate to Severe Chronic Prostatitis/Chronic Pelvic Pain Syndrome (TASC-P Trial): a Randomized, Sham Controlled Trial.

Not applicable Interventional Guang'anmen Hospital of China Academy of Chinese Medical Sciences · NCT06287970

This trial will try transcutaneous auricular vagus nerve stimulation (taVNS) to see if it reduces pain and urinary and mood symptoms in adults aged 18–50 with moderate to severe chronic prostatitis/CPPS.

What this trial studies

This is a prospective, randomized, sham-controlled trial enrolling 68 patients with moderate-to-severe CP/CPPS who meet EAU/CAU diagnostic criteria. Participants will be randomized 1:1 to receive either active taVNS or a sham taVNS intervention for 4 weeks, with an 8-week follow-up after treatment. Outcomes include NIH-CPSI, IPSS, EQ-5D, and measures of anxiety and depression (SAS, SDS), and adverse events will be recorded throughout. The trial is conducted at Guang'anmen Hospital, China Academy of Chinese Medical Sciences in Beijing.

Who should consider this trial

Good fit: Adults aged 18–50 diagnosed with CP/CPPS (symptoms >3 months in the last 6 months) with NIH-CPSI score ≥15, without infection or other clear pathological causes, are the intended participants.

Not a fit: People outside the 18–50 age range, those with infectious or other identifiable causes of pelvic pain, or those with only mild CP/CPPS symptoms (NIH-CPSI <15) are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, taVNS could offer a noninvasive treatment option to reduce pelvic pain and improve urinary symptoms and quality of life for people with CP/CPPS.

How similar studies have performed: Noninvasive vagus nerve stimulation has shown promise for some chronic pain and mood disorders, but applying taVNS specifically to CP/CPPS is relatively novel with limited prior data.
