Clinical Evaluation of the Efficacy and Safety of a Medical Device in the Form of Rectal Suppositories (Prospidol®) for the Treatment of Symptoms Associated With Chronic Prostatitis/Chronic Pelvic Pain Syndrome.

The goal of this clinical trial is to evaluate whether a medical device is effective and safe in treating chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) in adult men.

The main questions it aims to answer are:

* Does the treatment reduce pain symptoms (measured by NIH-CPSI score) by more than 30% after one month? * Does the treatment improve urinary symptoms, quality of life, and sexual function? * What adverse events or side effects occur during treatment? Researchers will conduct a multicenter, open-label study involving 40 participants diagnosed with CP/CPPS. All participants will receive the same treatment, and their outcomes will be monitored over time.

Participants will:

Use one suppository daily for 10 days each month for 3 months Attend clinical visits at the start of the study and after 30, 60, and 90 days Complete validated questionnaires (NIH-CPSI, IPSS, SF-36, IIEF) at each visit Report any side effects or symptoms throughout the study At the end of the study, researchers will analyze symptom improvement, quality of life changes, and treatment tolerability.

Inclusion criteria

  • male subjects aged between 18 and 60;
  • clinical presentation typical of prostatitis and a clinical diagnosis of chronic prostatitis type IIIa or IIIb (CP/CPPS) for at least 3 months;
  • no treatment for at least 2 months;
  • PSA < 3 ng/mL;
  • digital rectal examination negative for nodules or BPH;

  • other active prostate conditions;
  • patients with active neoplastic, neurodegenerative or immunological conditions, those who are immunocompromised, or those who are already taking supplements or functional foods for any reason;
  • patients undergoing treatment with systemic or topical corticosteroids;
  • patients who will not sign the informed consent form;

Treatment and study plan

Prospidol suppository

Device

Prospidol is a medical device containing sodium hyaluronate, Boswellia serrata extract (65% boswellic acid), mallow extract, rice bran oil and Eugenia caryophyllus essential oil. The recommended dosage is: 1 suppository per day, to be taken before bedtime, for 10 days a month, for 3 months.

Primary outcomes

  1. reduction of NIH-CPSI score

    Time frame: From enrollment to the end of treatment at 4 weeks

    The primary outcome of the study is the assessment of the reduction in the NIH-CPSI score after one month of treatment. Specifically, a reduction in pain symptoms of more than 30% compared with T0 is expected, given that the literature reports that patients with comparable characteristics, when treated with placebo, may experience a pain reduction of up to 30%.

Secondary outcomes

  1. Comparison of the NIH-CPSI scores

    Time frame: 0, 1, 2, 3 months after enrollment

    Comparison of the NIH-CPSI scores between baseline and follow-ups

  2. Comparison of the International Prostate Symptom Score (IPSS)

    Time frame: 0, 1, 2, 3 months after enrollment

    Comparison of the International Prostate Symptom Score (IPSS) between baseline and follow-ups

  3. Comparison of the SF-36 score

    Time frame: 0, 1, 2, 3 months after enrollment

    Comparison of the SF-36 score between baseline and follow-ups

  4. Comparison of the International Index of Erectile Funtion (IIEF)

    Time frame: 0, 1, 2, 3 months after enrollment

    Comparison of the International Index of Erectile Funtion (IIEF) score between baseline and follow-ups
