About this study

Official title: Evaluating Duloxetine's Analgesic Effectiveness in Chronic Pelvic Pain

This study is examining the effectiveness of duloxetine as a treatment for chronic pelvic pain in women. Duloxetine is FDA approved for the treatment of other pain conditions, including fibromyalgia and diabetic neuropathy.

Read the detailed description

Chronic pelvic pain in women can be caused by various pathologies, such as endometriosis, fibroids, and adhesions. Surgical treatment of the pathology often relieves the pain, but a significant number of women continue to have pain, even after visibly successful surgery. One model explored in this study is that in some cases of chronic pelvic pain, the central nervous system has changed in its processing of pain-related signals, requiring a therapy directed to the Central Nervous System (CNS) to effectively treat the pain. This model has been supported in studies of other chronic pain conditions, such as fibromyalgia and migraine. This study will seek to determine whether the analgesic effectiveness of duloxetine is related to the pain state of the individual.

What participants receive

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

  • DuloxetineDrug

    Also called Cymbalta

    30 mg dose once daily, administered orally for 1 week, 60 mg dose once daily, administered orally for 5 weeks, 30 mg dose once daily, administered orally for 1 week

  • PlaceboDrug

    Also called Sugar pill

    To serve as placebo for duloxetine. Administration schedule same as for active drug.

Study groups in NCT01451606
Study groupRoleWhat they receive
Placebo pillPlacebo comparatorA pill that looks like the active drug, but does not contain any active ingredients.
Receives: Drug: Placebo
DuloxetineActive comparatorThe drug, Duloxetine, is marketed under the trade name Cymbalta. It is a serotonergic and noradrenergic reuptake inhibitor (SNRI).
Receives: Drug: Duloxetine

What is being measured

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

  1. Change in Rating of Spontaneous Pelvic Pain (0 -10 Scale).

    The primary clinical efficacy measure is the change in spontaneous (non-evoked) pelvic pain from the baseline period to the end of treatment. This was assessed by using the 0-10 numerical pain ratings to derive the primary outcome variable of clinical pain intensity difference due to treatment. Larger values (greater changes in ratings) are better outcomes.

    Measured: Baseline and 8 weeks

Secondary outcomes (1)
  1. Change in Endometriosis Health Profile - 30 Subscale for Functional Limitations Due to Pain

    This is a questionnaire assessment of functional limitations due to clinical pain. The range of scores for this subscale is 0-44. The measure is the change in score from baseline to end of treatment period. A greater number (change in score) is a better outcome.

    Measured: Baseline and 8 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Duloxetine in people with Pelvis Pain Chronic, run by University of Maryland, Baltimore 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 3 inclusion and 20 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 26 Sep 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 23 Jan 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 in Rating of Spontaneous Pelvic Pain (0 -10 Scale). (time frame: Baseline and 8 weeks). 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 26 Sep 2019.
