About this study

Official title: Intravesical Instillation of Liposome Encapsulated Botulinum Toxin A (Lipotoxin) in Treatment of Interstitial Cystitis - a Randomized, Double-blind, Placebo-controlled, Prospective Study

To evaluate the efficacy and safety of intravesical instillation of Lipotoxin for the treatment of IC/BPS

Read the detailed description

Liposome has been proven able to carry botulinum toxin protein across the cell membrane and effect on urothelial receptors in human overactive bladder. However, the therapeutic duration is limited to 1 month. Intravesical BOTOX injection in patients with interstitial cystitis (IC) can effectively decrease pain, improve bladder capacity and decrease frequency. However, the need of cystoscopic injection limits its wide application.

A total of 100 eligible women with non-ulcer IC will be enrolled to receive intravesical instillation of Lipotoxin containing 80mg liposomes and 200U BOTOX (treatment group), 200U BOTOX in normal saline (N/S) (active control group) or normal saline (placebo control group) single treatment. At least 90 evaluable patients will be included for the final analysis.

All patients should have IC symptoms for at least 6 months, and proven to have grade 2 diffused glomerulations after cystoscopic hydrodistention (HD) within recent 1 year without Hunner's lesion. Patients should not have UTI in recent 12 months, no urinary tract stone. Patients should have been proven free of detrusor overactivity or bladder outlet obstruction. Patients should not receive intravesical hyaluronic acid treatment in recent 6 months, or intravesical Botox injection in recent 12 months. Intravesical instillation of Lipotoxin at OPD and the patient should hold the solution for 2 hours to allow bladder distention. Retreatment with Lipotoxin at 3 months if patient reports ineffective.

Primary end-point is the change of the O'Leary-Sant symptom score (including ICSI and ICPI) from baseline to 1 month after treatment. Secondary endpoints include VAS, daily frequency, nocturia and FBC as record in 3-day voiding diary, Qmax, voided volume, PVR and global response assessment (GRA). Four visits are required at baseline screening (before first treatment), treatment (V1), 2 weeks (V2), 4 weeks (V3, primary end-point) and 12 weeks (V4).

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Liposome encapsulated BoNT-A, BOTOX 200U in normal saline and Normal saline in people with Interstitial Cystitis, run by Buddhist Tzu Chi General 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 12 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 9 Mar 2017. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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 (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 NCT02247557, which also lists 1 linked publication.

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 9 Mar 2017.
