Study summary

The purpose of this study is to determine whether prostatic arterial embolization (PAE) compared is an effective and safe treatment for benign prostatic hyperplasia in patients with severe lower urinary tract symptoms not adequately controlled by medical therapy with alpha-blockers, as assessed by the the International Prostate Symptom Score (IPSS) after 6 months. Patients will be randomized on a 1:1 ratio to PAE or to a sham procedure and evaluated at 1, 3 and 6 months. Patients randomized to the sham procedure will be offered the possibility of performing PAE after 6 months. All patients may participate on an optional 6-months extension study.

Read the detailed description

This is a randomized, parallel-group, evaluator-blind, superiority, controlled clinical trial of PAE versus a sham procedure in patients with BPH with severe LUTS not adequately controlled by medical therapy with alpha-blockers.

This study has a screening visit at day -14, a baseline visit at day -2, a randomization and intervention visit at day 0, follow up visits at months 1, 3 and 6.

Patients initially randomized to the sham procedure and who completed the 6 month follow-up period will be offered the possibility of performing PAE at no cost. All patients will be invited to participate in a 6 months post-trial extension study.

Patients over 45 years-old with a diagnosis of BPH associated with severe LUTS defined by an IPSS>=20 after a minimum of 6 months treatment with alpha-blockers and with a prostate volume ≥ 40 mL will start a two weeks screening period. Eligible patients will be started either tamsulosin 0.4 mg q.d., alfuzosin 10 mg q.d. or silodosin 8 mg q.d., which will be maintained throughout the study period, and have the intervention scheduled for the following 2 days (study day 0), when they will be randomized to PAE or to a sham procedure if the procedure is technically feasible

Those patients in whom angiography has shown that PAE is technically feasible will be randomized to one of the study arms on a 1:1 ratio. Patients in both groups will be submitted to exactly the same procedure, except that patients randomized to the control group will not be injected with polyvinyl alcohol particles. Patients will be discharged as soon as their clinical condition is stabilized

Patients will be assessed at 1, 3 and 6 months with IPSS, QoL, IIEF, BPH-II and will perform prostatic ultrasonography, uroflowmetry and PSA at month 1 and 6. At 1 month a pelvic NMR will be performed to evaluate prostate volume and the degree of ischemia.

Patients completing the 6 month follow-up period will be invited to enter a 6 months extension study. In this extension study, patients will be evaluated at month 12 for all efficacy variables. Patients initially randomized to the sham procedure who wanted to perform PAE after the conclusion of the trial will be evaluated only at months 1, 3 and 6 after PAE.

Inclusion criteria

  • Male patients ≥ 45 years-old
  • Diagnosis of BPH based on clinical history, digital rectal examination, urine sediment, transrectal prostate ultrasound and PSA
  • Use of a marketed alpha-blocker for LUTS/BPH in the previous 6 months
  • Severe lower urinary tract symptoms at screening and baseline defined by all the following: IPSS (7 items) ≥ 20, QoL ≥ 3, Qmax \< 12 mL/s and prostate volume ≥ 40 mL
  • CTA shows that prostatic arteries are feasible for PAE
  • Sexual dysfunction or accepting the risk of developing sexual dysfunction after treatment
  • Written

Exclusion criteria

Exclusion Criteria:

  • Previous surgical or invasive prostate treatments such as TURP, TUMT, TUNA, laser or any other minimally invasive treatment
  • Acute or chronic prostatitis or suspected prostatitis including chronic pain, intermittent pain or abnormal sensation in the penis, testis, anal or pelvic area in the past 12 months
  • History of prostate or bladder cancer or pelvic irradiation
  • Active or recurrent urinary tract infections (more than 1 episode in the last 12 months)
  • History of neurogenic bladder or LUTS secondary to neurological disease
  • Advanced atherosclerosis and tortuosity of iliac and prostatic arteries
  • Secondary renal insufficiency (due to prostatic obstruction)
  • Large bladder diverticula or stones
  • Detrusor failure
  • Previous history of acute urinary retention
  • Current severe, significant or uncontrolled disease (including, but not limited to metabolic, hematologic, renal, hepatic, pulmonary, neurologic, endocrine, cardiac, infectious or gastrointestinal, uncontrolled hypertension (systolic ≥ 160 mmHg and/or diastolic ≥95 mmHg), congestive heart failure [ status of class III or IV], myocardial infarction within 26 weeks prior to randomization), which in the judgment of the clinical investigator renders the subject unsuitable for the trial and puts the subject at increased risk
  • Any bleeding disorder such as hemophilia, clotting factor deficiency, anti-coagulation or bleeding diathesis
  • or to tamsulosin use
  • Administration of 5-ARIs, finasteride and dutasteride in the previous 2 weeks and 4 months, respectively. These patients may be included if they stop those medications and replace them for tansulosin, alfuzosin or silodosin for at least 2 weeks and 4 months, respectively.
  • Any mental condition or disorder that would interfere with the subject's ability to provide
  • Participation in a study of any drug or device in the previous 3 months
Terms in these criteria, in plain language(5)

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.

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.

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.

Hypersensitivity

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.

Contraindication

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.

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.

Study arms

  • Experimental
    Prostatic Arterial Embolization

    Selective catheterization of the prostatic arteries followed by slow injection of Bead Block 300-500 or PVA 100+200 micra particles under fluoroscopic control.

    Procedure: Prostatic Arterial Embolization

  • Sham comparator
    Sham procedure

    Selective catheterization of the prostatic arteries followed by removal of the catheter with no particles injected.

    Procedure: Sham procedure

Interventions

  • ProcedureProstatic Arterial Embolization

    The prostatic arteries are selectively catheterized with a Progreat 2.7 microcatheter and an angiography is performed to confirm that the catheter is in the prostatic artery. Bead Block 300-500 or PVA 100+200 micra particles are slowly injected under fluoroscopic control until the end point is reached. Embolization is considered finished when there is "near stasis" in the prostatic vessels with interruption of the arterial flow and prostatic gland opacification checked in both oblique and AP views. Upon finishing the embolization of the left prostatic arteries, the right prostatic arteries are embolized in the same way.

  • ProcedureSham procedure

    The prostatic arteries are selectively catheterized with a Progreat 2.7 microcatheter and an angiography is performed to confirm that the catheter is in the prostatic artery. The catheter is removed and no particles are injected.
