XFLO Expander System for Enlarged Prostate
(EXPANDER-1 Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores a new device called the XFLO Expander System to determine if it can safely and effectively help men with symptoms from an enlarged prostate. The focus is on easing lower urinary tract symptoms, such as frequent urination or difficulty starting to urinate, caused by benign prostatic hyperplasia (BPH), a non-cancerous enlargement of the prostate. Participants will have the device implanted for varying durations—1, 6, or 12 months—to assess its effectiveness. Suitable candidates have experienced symptoms related to BPH and have not undergone prostate surgery or have certain other conditions. As an unphased trial, this study offers patients the chance to contribute to innovative research that could lead to new treatment options.
Will I have to stop taking my current medications?
If you are on BPH-related medications, you must have been on 5-alpha-reductase inhibitors for at least 3 months or alpha-blockers for at least 3 weeks with a stable voiding pattern. The protocol does not specify about other medications, but you should discuss your current medications with the trial team.
What prior data suggests that the XFLO Expander System is safe for treating lower urinary tract symptoms?
Research shows that the XFLO Expander System, also known as the Mercury Expander System, is being tested for its safety in treating urinary problems caused by an enlarged prostate. Studies indicate that this device is generally well-tolerated. Early results from a study called EXPANDER-1 found that the procedure is safe and minimally invasive, requiring no large cuts. Importantly, it might also help avoid the need for a catheter, a tube used to drain urine from the bladder, after the procedure.
Overall, these findings suggest that the XFLO Expander System could be a safe option for those with urinary issues from an enlarged prostate. However, as with any medical treatment, individual experiences may vary, and discussing options with healthcare providers is always recommended.12345Why are researchers excited about this trial?
Researchers are excited about the XFLO Expander System for enlarged prostate because it offers a novel, less invasive approach compared to traditional treatments like medication, surgery, or catheterization. Unlike these methods, the XFLO Expander System is a device implanted temporarily to relieve urinary symptoms by physically expanding the prostate, potentially reducing discomfort and recovery time associated with surgery. Additionally, the trial explores different implantation durations—1, 6, and 12 months—providing valuable insights into the optimal treatment length for effectiveness and patient comfort. This could lead to a more personalized treatment strategy, enhancing quality of life for patients with enlarged prostates.
What evidence suggests that the XFLO Expander System is effective for treating enlarged prostate?
Research shows that the XFLO Expander System holds promise for men experiencing difficulty urinating due to an enlarged prostate. One study demonstrated that the device provided quick relief, with a 40% improvement in symptoms just two weeks after implantation. In this trial, participants will be assigned to different arms, with the XFLO device implanted for varying durations: 1 month, 6 months, or 12 months. Patients who used the XFLO device for up to six months reported a significant drop in their symptom scores, which measure symptom severity. These early results suggest the device could be a helpful option for managing symptoms of an enlarged prostate.13567

Are You a Good Fit for This Trial?
Men over 50 with benign prostatic hyperplasia (BPH) causing urinary issues, who haven't taken BPH meds in the last 6 months or have a stable pattern on current meds. They should have a prostate size of 30-80 cc and meet specific criteria for urinary flow and symptoms. Excluded are those with other health conditions that could affect results, previous BPH procedures, certain medication use, or allergies to nickel.Inclusion Criteria
