Study summary

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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

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;
  • negative microbiological tests on urine and seminal fluid;
  • baseline score on the validated Italian version of the NIH-CPSI pain domain questionnaire > 7 or total NIH-CPSI score > 15;
  • digital rectal examination not suggestive of prostate cancer.

Exclusion criteria

Exclusion Criteria:

  • patients with signs of infection and a PSA level > 3 ng/ml;
  • other active prostate conditions;
  • patients with active neoplastic, neurodegenerative or immunological conditions, those who are , or those who are already taking supplements or functional foods for any reason;
  • patients undergoing treatment with systemic or topical ;
  • patients who will not sign the form;
  • patients unable to participate in a clinical trial for any reason (e.g. psychiatric patients, those with cancer, on dialysis, or with severe liver or kidney failure);
  • patients with allergies to any of the components of the medical device (MD) under investigation.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    Prospidol

    patients enrolled in this arm will take 1 Prospidol suppository per day, to be administered before going to bed for 10 days each month, for a total period of 3 months

    Device: Prospidol suppository

Interventions

  • DeviceProspidol suppository

    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.

What researchers measure

Primary outcomes

  1. Change of National Institutes of Health - Chronic Prostatitis Symptom Index (NIH-CPSI) score

    The primary outcome of the study is the assessment of the change in the National Institutes of Health - Chronic Prostatitis Symptom Index (NIH-CPSI score, ranging from 0 to 43, where an improvement in symptoms is characterised by a decrease in the score) after one month of treatment. Specifically, a change 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%.

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

Secondary outcomes

  1. Comparison of the National Institutes of Health - Chronic Prostatitis Symptom Index (NIH-CPSI) scores

    Comparison of the National Institutes of Health - Chronic Prostatitis Symptom Index (NIH-CPSI, ranging from 0 to 43, where an improvement in symptoms is characterised by a decrease in the score) scores between baseline and follow-ups

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

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

    Comparison of the International Prostate Symptom Score (IPSS, ranging from 0 and 35, where an improvement in symptoms corresponds to a decrease in the score) between baseline and follow-ups

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

  3. Comparison of the Short Form 36 (SF-36) score

    Comparison of the Short Form 36 (SF-36, ranging from 0 to 100, where an improvement in symptoms corresponds to a decrease in the score) score between baseline and follow-ups

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

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

    Comparison of the International Index of Erectile Funtion score(IIEF, ranging from 5 to 25, where an improvement in symptoms corresponds to a higher score) between baseline and follow-ups

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