Details and patient eligibility


This is a randomized, multi-center, double-blind, parallel-group study, enrolling approximately 100 male subjects diagnosed with CP/CPPS to evaluate the effect of 12-week treatment with AQX-1125 (active drug) compared to placebo. The subjects will be randomized to receive orally once-daily either AQX-1125 (200 mg) or placebo in a 1:1 ratio across approximately 30 centers in North America (United States and Canada). The study will consist of a screening period of up to 3 weeks, a 12-week treatment period followed by a 4-week off drug safety follow-up period, and an ophthalmic safety follow-up call at 3 months and visit at 6 months post last dose, for a total study duration of about 41 weeks.

  • Have had an unresolved (positive bacterial urine culture) urinary tract infection within 8 weeks (inclusive) prior to Screening Visit 1
  • History of previous prostate or bladder intervention within 1 month of Screening Visit 1, history of microwave therapy, transurethral resection of the prostate, transurethral radiofrequency thermotherapy, transurethral incision of the prostate, transurethral needle ablation, transurethral laser vaporization of the prostate, Urolift®, Rezum, and other urological interventions within 6 months of Screening Visit 1
