Trial summary

The purpose of this study is to evaluate the safety of a new product that uses human gene transfer (called hMaxi-K) when it is given to patients with overactive bladder. Human gene transfer is a new type of therapy that is the process of placing genetic material (DNA or RNA) into a person. Read more about this study

About this study

Official title: A Phase 1 Multicenter Study Evaluating the Safety and Potential Activity Of Three Escalating Doses of hMaxi-K Gene Transfer In Female Participants With Overactive Bladder Syndrome and Detrusor Overactivity: Double Blind, Imbalanced Placebo Controlled Design Within 3 Sequential Active Treatment Groups

The purpose of this study is to evaluate the safety of a new product that uses human gene transfer (called hMaxi-K) when it is given to patients with overactive bladder. Human gene transfer is a new type of therapy that is the process of placing genetic material (DNA or RNA) into a person. The primary objective of this study is to evaluate safety parameters occurring subsequent to administration of a single intravesical instillation of study drug.

Two different dose groups of hMaxi-K will be tested in this study: 5000 and 10000 micrograms. A 15000 microgram group was planned; however, the study was terminated before participants were dosed. hMaxi-K will be given as a single administration into the bladder through a catheter. Each women's participation in the study will last for up to 24 weeks (followed by an additional 18-month follow-up period).

Read the detailed description

The safety parameters to be monitored include: adverse events, clinical laboratory tests, electrocardiograms, and physical examinations.

The secondary objective is to evaluate the efficacy of a single intravesical instillation of hMaxi-K compared to the control group. Efficacy parameters that will be evaluated are: mean number of micturitions per 24 hours, mean number of urge incontinence episodes per 24 hours, mean number of urgency episodes per 24 hours, overall maximum bladder capacity, number of uninhibited contractions during the cystometry procedure, participant rating of urgency score, participant rating of perceived bladder condition severity, participant assessment of response to treatment, participant rating of Quality of Life (Kings Health Questionnaire), SF-12 Health Survey, International Consultation on Incontinence Questionnaire (ICIQ-SF), and pad weight measurement of accidental bladder leaks.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing hMaxi-K in people with Overactive Bladder, run by Urovant Sciences GmbH at 1 site in United States.

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 6 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: stopped early, as of the sponsor's last update on 28 Jun 2019. 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 United States. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 was stopped early (reason given: Slow enrollment and financial issues). Results are not available in the source record.

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?

Number of participants with any treatment-emergent adverse event during the treatment period (time frame: 6 months (24 weeks per participant)). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 28 Jun 2019.
