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.
827 studies on the registry are indexed under Prostatic Hyperplasia; 179 are open to participants now.
This study's enrollment of 162 is above the median of 92 across 626 interventional studies indexed under Prostatic Hyperplasia.

Exclusion Criteria:
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.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
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.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
Contraindication

The Optilume™ BPH, Prostatic Dilation DCB Catheter is a dilation catheter used to exert radial force to dilate the prostatic urethra resulting in a commissurotomy. The distal end of the catheter has a semi-compliant inflatable double lobe balloon that is coated with a proprietary coating containing the active pharmaceutical paclitaxel.
Device: Optilume BPH Catheter System
The Sham Device is a 21 Fr Optilume BPH, Prostatic Pre-dilation Catheter within the sheath.
Device: Optilume Sham Device
A single arm of 15 non-randomized subjects will be treated in the pharmacokinetics (PK) arm. These subjects will be treated with the Optilume BPH Catheter System

21 Fr sheathed Optilume™ BPH Prostatic Pre-dilation Catheter (modified to prevent inflation)
Number of Participants With >30% Improvement in the International Prostate Symptom Score (IPSS)
The primary efficacy endpoint was the improvement in International Prostate Symptom Score (IPSS) at 12 months in the Optilume BPH arm compared to the improvement in IPSS at 3 months in the Sham arm with a super-superiority margin on 25%. The IPSS contains the well-validated, highly reliable and responsive American Urological Association symptom score (AUASS) assessment to identify the severity of BPH symptoms. The first seven questions in the IPSS address frequency, nocturia, weak urinary stream, hesitancy, intermittence, incomplete emptying, and urgency, and scored on a 6-point scale (0 to 5). The IPSS can be interpreted as follows: 0-7 mildly symptomatic, 8-19 moderately symptomatic, and 20-35 severely symptomatic. The IPSS also includes an eighth question that is designed to assess the degree of "bother" associated with the subject's urinary symptoms. Answers range from "delighted" to "terrible" (0-6). This question is not included in the calculation of the main IPSS score.
Time frame: 12 months
Number of Participants With Major Device Related Serious Complications
Rate of major device-related serious complications. A major device-related serious complication is defined as any of the following events through 12 months: * Device-related rectal fistula or GI fistula * Device-related formation of fistula between the rectum and urethra * Device-related new onset severe urinary retention lasting \> 14 consecutive days post-healing * Device-related unresolved new onset stress urinary incontinence by 90 days * Device-related bleeding requiring transfusion * Device-related urethra or prostatic capsule rupture requiring surgical intervention
Time frame: 12 months
162 subjects will be randomized and/or treated in the study at up to 30 clinical sites in the United States and Canada. Up to 625 subjects will be enrolled (i.e. consented) in the study in order to identify 162 eligible subjects to be randomized and/or treated. All subjects treated with the Optilume BPH Catheter System will be followed annually through 5 years. Study duration is approximately 8 years.
