What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is evaluating two methods for addressing prostate issues to determine which one better improves symptoms in patients.

Do I need to stop my current medications for the trial?

The trial information does not specify if you need to stop taking your current medications. It might be best to discuss this with the trial coordinators or your doctor.

Is embolization using Embosphere Microspheres or tris-acryl gelatin microspheres safe for humans?

Research shows that embolization using Embosphere Microspheres and tris-acryl gelatin microspheres is generally safe for treating conditions like benign prostatic hyperplasia, with light adverse reactions and no major complications reported in studies.12345

How does the Embosphere Microspheres treatment for enlarged prostate differ from other treatments?

The Embosphere Microspheres treatment is unique because it involves prostatic artery embolization (PAE), a minimally invasive procedure that reduces blood flow to the prostate, leading to its shrinkage and relief of symptoms. This approach is different from traditional surgical methods, as it uses tiny spheres to block blood vessels, offering a less invasive option with fewer complications.12346

What data supports the effectiveness of this treatment for an enlarged prostate?

Research shows that using embosphere microspheres for prostatic artery embolization (PAE) is effective in treating symptoms of an enlarged prostate, with good safety and fewer side effects compared to other methods. Additionally, the HoLEP procedure is a standard treatment for benign prostatic hyperplasia (BPH) and is effective in reducing symptoms, although it may cause some postoperative complications.12367

Are You a Good Fit for This Trial?

Men over 50 with enlarged prostates (80-250 grams) and moderate to severe symptoms not improved by medication can join this study. They must have an IPSS Score >13, indicating significant urinary issues, and be eligible for PAE or HoLEP procedures. Those who've had certain prostate treatments in the last year, have serious bleeding disorders, allergies to specific medical substances, untreated infections, cancer diagnoses, or other major health conditions cannot participate.

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Treatment

Participants undergo either prostate artery embolization (PAE) or Holmium laser enucleation of prostate (HoLEP) for treatment of symptomatic benign prostatic hyperplasia

Up to 48 hours for hospitalization and urinary catheterization

Follow-up

Participants are monitored for changes in BPH symptoms, erectile function, retrograde ejaculation, PSA levels, and other outcomes

What Are the Treatments Tested in This Trial?

Interventions

  • Embosphere Microspheres
  • HoLEP Procedure
Trial Overview The trial is comparing two different procedures for treating an enlarged prostate: Prostate Artery Embolization (PAE), which blocks blood flow to reduce size; and Holmium Laser Enucleation of Prostate (HoLEP), a laser treatment that removes excess tissue. The goal is to see which method better improves symptoms.

Published Research Related to This Trial

In a study of 422 patients with prostatic hyperplasia, treatment with embosphere microspheres showed better safety and efficacy compared to gelatin sponge particles, with fewer adverse reactions and a lower chance of recurrent bleeding.
The use of embosphere microspheres resulted in less damage to prostatic function post-treatment, making it a favorable option for managing complications from prostatic hyperplasia.

In a Phase I study involving 30 patients, the use of tris-acryl gelatin microspheres for uterine artery embolization was technically successful in all cases, leading to significant improvements in menstrual bleeding and pelvic pain within three months.
The treatment was found to be safe, with only minor complications reported in nine patients and no major complications, indicating that this method could be a viable option for managing symptomatic leiomyomata.
