optilume™ bph catheter system in men with symptomatic bph

Conditions: Benign Prostatic Hyperplasia

Summary: pinnacle is a prospective, multi-center, randomized control clinical trial to establish the safety and efficacy of the optilume™ bph catheter system in the treatment of benign prostatic hyperplasia (bph)

this is a prospective, multi-center, double blind, randomized controlled clinical trial in a 2:1 allocation of test versus sham control. in addition, a single arm of 15 non-randomized subjects will be added to study the pharmacokinetics of the drug. the objectives of the study are to assess the efficacy of optilume bph catheter system to alleviate luts believed to be secondary to bph (luts/bph) and to evaluate the safety of optilume bph catheter system in the treatment of luts/bph.

evidence of stable dosing for at least 6 months 19. use of antidepressants with adrenergic effects (i.e. duloxetine, imipramine and amitriptyline), long-acting anticholinergics (laac) for chronic obstructive pulmonary disease (copd), or androgens within 2 weeks prior to baseline assessment unless there is documented evidence of stable dosing for at least 3 months prior to baseline assessment 20. use of luteinizing hormone-releasing hormone (lhrh) analogs within 12 months prior to baseline assessment 21. use of type ii 5-alpha reductase inhibitor \[e.g. finasteride (proscar, propecia)\]

suppression unless there is documented evidence of stable dosing for at least 3 months prior to baseline assessment 24. use of alpha blockers or daily dose pde5 inhibitor (e.g. cialis) within 2 weeks of baseline assessment 25. use of warfarin or novel oral anti-coagulants \[e.g., apixaban (eliquis), fondaparinux (arixtra), rivaroxaban (xarelto) or edoxaban (savaysa)\], unless the medication is safely discontinued prior to the procedure and is not planned to be restarted for at least 5 days post-procedure 26. use of anti-platelet medications (e.g., clopidogrel, aspirin) within 10 days prior to the procedure or planned use within 5 days post-procedure 27. history of hypersensitivity reactions to paclitaxel, on medication that may have negative interaction with paclitaxel, presence of solid tumor with a baseline neutrophil count of \<1500 cells/mm3 or aids-related kaposi's sarcoma with baseline neutrophil count of \<1000 cells/mm3 28. incidence of spontaneous urinary retention

(except basal cell or squamous cell carcinoma of the skin). a potential participant is considered in complete remission if there has been no evidence of cancer within five years 34. current uncontrolled diabetes (i.e. hemoglobin a1c ≥ 8%) 35. history of clinically significant comorbidities or presence of unstable conditions \[e.g. cardiovascular, lung, renal (serum creatinine \> 2.0 mg/dl), hepatic, bleeding disorders or metabolic impairment\] that may confound the results of the study or have a risk to subject per investigator's opinion 36. any cognitive disorder that interferes with or precludes direct and accurate communication with the study investigator regarding the study or affects the ability to complete the study quality of life questionnaires 37. life expectancy \< 10 years 38. anatomy (e.g. presence of false passage or size of meatus) is not suitable for treatment in this study 39. significant median lobe component \[e.g. intravesical prostatic protrusion (ipp)
