Study summary

Efficacy and safety of the medical device rectal CANNEFF® SUP suppositories containing two active ingredients cannabidiol (CBD) and hyaluronic acid (HA) in alleviating non-bacterial prostatitis symptoms and improving quality of life in men will be evaluated.

Read the detailed description

Chronic non-bacterial prostatitis/chronic pelvic pain syndrome (CP/CPPS) is the third most common urogenital diagnosis in men, following benign prostatic hyperplasia and prostate cancer, with an estimated prevalence reaching 8.2%. Clinically, CP/CPPS often presents with persistent pelvic pain, lower urinary tract symptoms (LUTS), and sexual dysfunction, all of which can substantially diminish quality of life. Psychological comorbidities, including anxiety, stress, and depression, further amplify the burden on patients. Despite its considerable socioeconomic impact, no definitive treatment consensus exists for CP/CPPS. This study assessed the effects of rectal administration of cannabidiol (CBD)-based therapy in men with CP/CPPS. A single-arm, open-label pilot trial on men with CP/CPPS (NIH Chronic Prostatitis Symptom Index [NIH-CPSI] >10, pain subscore ≥4). The participants self-administered rectal CANNEFF® suppositories containing CBD (100 mg) and hyaluronic acid (HA = 6.6 mg) as active ingredients, nightly for 30 days. Outcome measures included changes in NIH-CPSI total score, International Prostate Symptom Score (IPSS), and International Index of Erectile Function (IIEF-5). Safety and tolerability were assessed.

What researchers measure

Primary outcomes

  1. Alleviating Chronic Non-bacterial Prostatitis Symptoms

    The primary outcome was the change in NIH Chronic Prostatitis Symptom Index (NIH-CPSI) total score between baseline (Day 0) and Day 30. The NIH-CPSI has a total score range from 0 to 43, and it includes three subscales addressing pain (score range 0-21), urinary symptoms (score range 0-10), and quality of life (QOL) (score range 0-12). Higher score means a worse outcome.

    Time frame: 30 days

  2. Alleviating Chronic Pelvic Pain Symptoms

    The changes in the NIH-CPSI pain subscore (score range 0-21) were evaluated to capture the specific impact on pelvic pain. Higher score means a worse outcome.

    Time frame: 30 days

Secondary outcomes

  1. International Prostate Symptom Score Evaluation

    Secondary outcome measures included the International Prostate Symptom Score (IPSS). The IPSS evaluates lower urinary tract symptoms (both storage and voiding). A score of 0 to 7 indicates mild symptoms, 8 to 19 indicates moderate symptoms and 20 to 35 indicates severe symptoms. The index was assessed at baseline and again on Day 30.

    Time frame: 30 days

  2. Erectile Function Evaluation

    The five-item International Index of Erectile Function (IIEF-5) was evaluated, whereas the IIEF-5 provides a brief assessment of erectile function (higher scores indicating better function). Interpretation: score 22-25 - No erectile dysfunction, 17-21 - Mild erectile dysfunction, 12-16 - Mild to moderate erectile dysfunction, 8-11 - Moderate erectile, 5-7 - Severe erectile dysfunction. The index was assessed at baseline and again on Day 30.

    Time frame: 30 days

  3. Safety Profile Evaluation

    Adverse events reported were monitored after 30 d of intervention.

    Time frame: 30 days
