About this study

Official title: A Multicenter, Double-Blind, Randomized, Placebo-Controlled Study to Evaluate the Efficacy and Safety of Botulinum Toxin Type A for Injection in Chinese Subjects With Overactive Bladder (OAB)

This is a multicenter, double-blind, randomized, placebo-controlled study designed to evaluate the efficacy and safety of Botulinus Toxin Type A for Injection (HengLi®) in patients with overactive bladder (OAB) . Approximately 216 subjects will be enrolled. Subjects will be randomized 2:1 to receive intradetrusor injection of Botulinus Toxin Type A for Injection (HengLi®) 100 U or placebo. The study contains two parts: core double-blinded phase and extension phase. In the core double-blinded phase, eligible subjects must attend three study visits posttreatment 12 weeks. During the extension phase, subjects must also attend three study visits (12 weeks). The primary efficacy variables is the change from baseline in the daily average frequency of micturition at week 6 after the first treatment.A 3-day paper bladder diary will be used before each study visits (screening period, the second week, the sixth week, the twelfth week, the fourteenth week, the eighteenth week and the twenty fourth week ) to collect all OAB symptoms (episodes of urgency, incontinence, micturition and nocturia) and volume per voidSafety parameters will also be measured, including adverse events, vital signs (pulse and blood pressure) and clinical laboratory tests (haematology, serum chemistry and urinanalysis).

Read the detailed description

Eligible patients will be randomized on day 1 to receive double-blind treatment with Botulinus Toxin Type A for Injection (HengLi®) 100U or placebo in a 2:1 ratio. A total of 216 subjects will be randomized into this study. Followup visits will occur at day 0, week 6 and 12, and week 14, 18 and 24 thereafter until study exit at week 24 unless re-treatment was necessary. The primary efficacy variables is the change from baseline in the daily average frequency of micturition at week 6. After a screening period of 1 week, all eligible patients will be randomized to receive a single intramuscular treatment with Botulinus Toxin Type A for Injection (HengLi®) or placebo at day 0 (visit 0).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Botulinum Toxin Type A for InjectionDrug

    Also called HengLi®

    In these studies,patients received a minimum intramuscular(IM) dose of 100U of Botulinum Toxin Type A administered to 20 injection sites

  • PlaceboDrug

    In these studies,patients received placebo administered to 20 injection sites

What is being measured

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

  1. average frequency of micturition

    The primary efficacy variables is the change from baseline in the daily average frequency of micturition at week 6 after the first treatment.

    Measured: Baseline(week -1 to 0)and core phase(week 6)

Secondary outcomes (8)
  1. The change from baseline in the daily average frequency of urgency episodes and the scores.

    The degree of urgency is divided into 5 grades (With 0 points representing no hurry, hurry on behalf of 5 points, 1~5 points gradually increase depending on the degree of urgency)

    Measured: Baseline and Week 2,6,12,14,18,24

  2. average frequency of UI episodes

    The change from baseline in the daily average frequency of UI episodes

    Measured: Baseline and Week 2,6,12,14,18,24

  3. volume per micturition

    The change from baseline in volume voided per micturition

    Measured: Baseline and Week 2,6,12,14,18,24

  4. maximum cystometric capacity (MCC)

    The change from baseline in MCC at week 6 after the first treatment ( Only in patients with neurogenic overactive bladder )

    Measured: Baseline(week -1 to 0)and core phase(week 6)

  5. maximum detrusor pressure during first involuntary detrusor contraction (PdetmaxIDC)

    The change from baseline in PdetmaxIDC at week 6 after the first treatment ( Only in patients with neurogenic overactive bladder )

    Measured: Baseline(week -1 to 0)and core phase(week 6)

  6. volume at first IDC (VPmaxIDC)

    The change from baseline in VPmaxIDC at week 6 after the first treatment ( Only in patients with neurogenic overactive bladder )

    Measured: Baseline(week -1 to 0)and core phase(week 6)

  7. The change from baseline in the QOL score

    The change from baseline in the QOL score

    Measured: Baseline and Week 2,6,12,14,18,24

  8. The change from baseline in the OABSS total summary score

    The change from baseline in the OABSS total summary score

    Measured: Baseline and Week 2,6,12,14,18,24

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Botulinum Toxin Type A for Injection in people with Overactive Bladder, run by Lanzhou Institute of Biological Products Co., Ltd.

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 5 inclusion and 19 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: status not confirmed, as of the sponsor's last update on 3 Jan 2018. Status can change between updates, so confirm with the study contact before making plans.

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

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?

average frequency of micturition (time frame: Baseline(week -1 to 0)and core phase(week 6)). 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 3 Jan 2018.
