About this study

Official title: Low Energy Shock Wave for the Treatment of Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) - a Randomized, Double-blind, Placebo-controlled, Prospective Study

To investigate the efficacy and safety of LESW on participants with IC/BPS

Read the detailed description

Low energy shock wave (LESW) is known to facilitate tissue regeneration with analgesic and anti-inflammatory effects. LESW has been proved to have therapeutic effects in patients with nonbacterial prostatitis and chronic pelvic pain syndrome (CPPS). Investigator's previous study has demonstrated that LESW treatment inhibited nerve growth factor (NGF), interleukin-6 (IL-6), and cyclooxygenase-2 (COX-2) expression, and blocked the bladder pain, inflammation and overactivity in a cyclophosphamide induced cystitis model in rats. These findings suggest that a potential clinical benefit of LESW treatment for patients with interstitial cystitis/bladder pain syndrome (IC/BPS).

A total of 50 participants with IC/BPS will be enrolled to receive LESW (transcutaneous applied to the suprapubic bladder region with 2000 shocks, frequency of 3 pulses per second and maximum total energy flow density 0.25 millijoule/mm2) once a week for 4 weeks or placebo (same condition but with no energy) treatment.

All participants should have IC symptoms for at least 6 months, and have received cystoscopy to rule out other bladder lesion. Participants should not have urinary tract infection (UTI) in recent 3 months, and no urinary tract stone. Participants should not receive intravesical hyaluronic acid treatment in recent 3 months, or intravesical Botox injection in recent 12 months. Retreatment with LESW at 3 months if participants reports ineffective.

Primary end-point is the change of the O'Leary-Sant symptom score (OSS), including Interstitial Cystitis Symptom Index (ICSI) and Interstitial Cystitis Problem Index (ICPI) from baseline to 1 month after treatment. Secondary endpoints include Visual Analogue Scale (VAS), daily frequency, nocturia and functional bladder capacity (FBC) as record in 3-day voiding diary, maximum flow rate (Qmax), voided volume, postvoiding residual (PVR) and global response assessment (GRA). Two visits are required at baseline screening (before first treatment), treatment (V1), 1 week (V2), 2 weeks (V3), 3 weeks (V4) and 1 week post V4 treatment (V5), 1 month post V4 treatment (V6, primary end-point), and 3 months post V4 treatment (V7) . Urine samples will be collected at each time-point for NGF and cytokines tests. Bladder biopsy will be performed at baseline and repeat cystoscopy at 3 months post treatment optional.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change of the O'Leary-Sant symptom score (OSS, including ICSI and ICPI)

    Change of the O'Leary-Sant symptom score from baseline to 1 month after the treatment day.

    Subscales ICSI and ICPI are graded from 0 to 20 and 0 to 16, respectively. The items are summed to obtain OSS (range from 0 to 36, higher values represent a worse outcome).

    Measured: Baseline and 1 month

Secondary outcomes (9)
  1. Net changes of the Visual Analog Scale (VAS)

    Net changes of the Visual Analog Scale from baseline to 1 month after the treatment day (VAS range from 0 to 10, higher values represent a worse outcome)

    Measured: Baseline and 1 month

  2. Net changes of the functional bladder capacity (FBC) as assessed by the maximum urine volume (milliliters) as recorded in 3-day voiding diary

    Net changes of the functional bladder capacity (FBC) from baseline to 1 month after the treatment day (higher FBC volumes represent a better outcome)

    Measured: Baseline and 1 month

  3. Net changes of the voiding frequency at daytime as recorded in 3-day voiding diary

    Net changes of the voiding frequency at daytime as recorded in 3-day voiding diary from baseline to 1 month after the treatment day (higher voiding frequency at daytime represent a worse outcome)

    Measured: Baseline and 1 month

  4. Net changes of the voiding frequency at night time as recorded in 3-day voiding diary

    Net changes of the voiding frequency at night time as recorded in 3-day voiding diary from baseline to 1 month after the treatment day (higher voiding frequency at night time represent a worse outcome)

    Measured: Baseline and 1 month

  5. Net changes of the Global response assessment (GRA)

    Global response assessment (GRA) of therapeutic result by the patient (categorized from -3 to +3, indicating markedly worse to markedly improved) at 3 months after the last treatment day

    Measured: Baseline and 3 month

  6. Net changes of the maximum flow rate

    Net changes of the maximum flow rate from baseline to 1 month after the treatment day (higher maximum flow rate represent a better outcome)

    Measured: Baseline and 1 month

  7. Net changes of the voided volume

    Net changes of the voided volume from baseline to 1 month after the treatment day (higher voided volumes represent a better outcome)

    Measured: Baseline and 1 month

  8. Net changes of the PVR

    Net changes of the PVR from baseline to 1 month after the treatment day (higher PVR volumes represent a worse outcome)

    Measured: Baseline and 1 month

  9. Net changes of the cytokines level

    Net changes of the cytokines level from baseline to 1 month after the treatment day (e.g. NGF and IL-6, higher values represent a worse outcome)

    Measured: Baseline and 1 month

Double blind, placebo control study. Eligible participants will be assigned a randomization number in sequential order and each of the randomization will determine the allocation of one of the two treatment groups (LESW and Placebo) in 1: 1 ratio as shown below. The LESW and placebo will be controlled by a research assistance who will not evaluate the therapeutic outcome to ensure the double blind method.

Questions about this trial

What is this clinical trial studying?

A study testing Low energy shock wave in people with Interstitial Cystitis, run by Chang Gung Memorial Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change of the O'Leary-Sant symptom score (OSS, including ICSI and ICPI) (time frame: Baseline and 1 month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03619486, which also lists 19 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Feb 2021.
