Study summary

The ALPFA Medical BPH Pilot Study is a prospective, open label, single arm pilot study to assess the use of the ALPFA BPH PFA System in the treatment of men over the age of 45 with obstructive urinary symptoms associated with BPH.

Male subjects will be consented and undergo protocol-defined baseline assessments. Those who meet study entry criteria will be enrolled and treated with the ALPFA BPH PFA System and then undergo follow-up with protocol-defined assessment.

Inclusion criteria

  1. Patients who are ≥ 45 years of age on the day of enrollment.
  2. Patients who have failed to achieve satisfactory resolution of BPH symptoms using an approved medication.
  3. : the patient has a life expectancy of ≥ 1 year
  4. Patient participation: The patient

    1. is free of physical, psychological or other impairment that would prevent their ability to understand and comply with all study requirements.
    2. is willing and capable of providing to undergo study procedures.
    3. agrees to fully participate in all examinations, study requirements, follow-up visits and tests associated with this clinical study.
    4. lives close enough to the site to facilitate the required in-person visits.

Exclusion criteria

Exclusion:

  1. Urologic conditions that would prevent participation in the study, interfere with assessment or therapy, significantly raise the risk of study participation, or confound data or its interpretation, including but not limited to:

    1. Previous operative intervention for BPH
    2. Active urinary tract infection (may be treated and enrolled upon negative urine culture).
    3. Prostatitis: a history of any prostatitis within 2 years of enrollment.
    4. Cystolithiasis active within 90 days of enrollment
    5. artificial sphincters.
  2. Bladder cancer: a history of treated bladder cancer of Stage T2 or higher, or a clinical suspicion of bladder cancer
  3. Medical conditions that would prevent participation in the study, interfere with assessment or therapy, significantly raise the risk of study participation, or confound data or its interpretation, including but not limited to:

    a. Unstable cardiovascular disease including: i. III/IV heart failure or \< 40% ii. Uncontrolled arrhythmia iii. Stroke, , thromboembolic event, myocardial infarction, unstable angina, percutaneous coronary intervention or any cardiac surgery within 90 days of enrollment iv. Uncontrolled hypertension b. : Known immunosuppression, including but not limited to AIDS, immunosuppressive medication or current chemotherapy.

Terms in these criteria, in plain language(7)

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.

Life expectancy

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.

Informed consent

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.

Investigational drug or device

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.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

TIA (transient ischaemic attack)

A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.

Stroke symptoms need emergency care at once, even if they go away.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.
