One-year outcomes after treatment with a drug-coated balloon catheter system for lower urinary tract symptoms related to benign prostatic hyperplasia

Abstract

BackgroundThis is the first report of the 1-year outcomes of the EVEREST-I study evaluating the safety and efficacy of the Optilume® BPH Catheter System, a prostatic paclitaxel-coated balloon catheter system, for the treatment of lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH).MethodsSubjects were men >50 years old with moderate-to-severe LUTS secondary to BPH, peak urinary flow rate of 5–15 ml/s, prostatic urethra length 30–55 mm, and prostate volume 20–80 g. All were treated with the Optilume BPH Catheter System and followed at Foley removal, 2 weeks, 30 days, 3, 6, and 12 months after treatment. The primary endpoint was the proportion of subjects with ≥40% improvement in International Prostate Symptom Score (IPSS). The rate of post-procedural complications was evaluated.ResultsEighty subjects were treated at six sites in Latin America and 75 completed the 1-year follow-up. The percent of subjects with an improvement ≥40% in IPSS from baseline was 81% at 3 months and 1 year. IPSS improved from 22.3 at baseline to 7.9 at 1 year, Qmax improved from 10.9 to 18.4 ml/s, and IPSS QoL improved from 4.6 to 1.3. Post-procedural complications included common urologic events and the rate of complications was significantly impacted by device diameter.ConclusionsTreatment with the minimally invasive Optilume BPH Catheter System is safe and showed subjective and objective improvements in LUTS. Benefits were rapid and persisted through 1 year. The initial results warrant further evaluation of this therapy as a treatment option for patients with LUTS related to BPH.
