What is being measured

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

  1. Change From Baseline at Week 12 in Average Pain Severity Rating Using Diaries for the Combined Duloxetine Arms (40 mg + 60 mg)

    Average pain severity was measured using an 11-point numerical rating scale, collected by diaries and expressed as weekly mean. The scale is a self-reported instrument that measures the severity of pain based on the average pain over the past 24-hours. The severity scores range from 0 (no pain) to 10 (pain as severe as you can imagine).

    Measured: Baseline, 12 weeks

Secondary outcomes (11)

    Measured: Week 12

  6. Change From Baseline in Brief Pain Inventory Severity Scores at Week 12 for the Combined Duloxetine Arms (40 mg + 60 mg)

    A self-reported scale that measures the severity of pain. The severity scores range from 0 (no pain) to 10 (pain as severe as you can imagine). There are 4 questions assessing worst pain, least pain, and average pain in the past 24 hours, and the pain right now. Each question has a total range of scores from 0 to 10.

    Measured: Baseline, Week 12

  7. Change From Baseline in Brief Pain Inventory Severity Scores at Week 12

    A self-reported scale that measures the severity of pain. The severity scores range from 0 (no pain) to 10 (pain as severe as you can imagine). There are 4 questions assessing worst pain, least pain, and average pain in the past 24 hours, and the pain right now. Each question has a total range of scores from 0 to 10.

    Measured: Baseline, Week 12

  8. Change From Baseline in Brief Pain Inventory Interference Scores at Week 12 for the Combined Duloxetine Arms (40 mg + 60 mg)

    The Interference scores range from 0 (does not interfere) to 10 (completely interferes). There are 7 questions assessing the interference of pain in the past 24 hours for general activity, mood, walking ability, normal work, relations with other people, sleep, and enjoyment of life. Each question has a total range of scores from 0 to 10.

    Measured: Baseline, Week 12

  9. Change From Baseline in Brief Pain Inventory Interference Scores at Week 12

    The Interference scores range from 0 (does not interfere) to 10 (completely interferes). There are 7 questions assessing the interference of pain in the past 24 hours for general activity, mood, walking ability, normal work, relations with other people, sleep, and enjoyment of life. Each question has a total range of scores from 0 to 10.

    Measured: Baseline, Week 12

  10. Change From Baseline in Beck Depression Inventory-II (BDI-II) Total Score at Week 12 for the Combined Duloxetine Arms (40 mg + 60 mg)

    A 21-item, patient-completed questionnaire to assess characteristics of depression. Each of the 21 items corresponding to a symptom of depression is summed to give a single score. There is a four-point scale for each item ranging from 0 to 3. Total score ranges from 0 (no depression) to 63 (severe depression).

    Measured: Baseline, Week 12

  11. Change From Baseline in Beck Depression Inventory-II (BDI-II) Total Score at Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Duloxetine hydrochloride - 40 mg and Duloxetine hydrochloride - 60 mg in people with Diabetic Neuropathies, run by Eli Lilly and Company at 25 sites in Japan.

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 4 inclusion and 5 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 13 Apr 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 25 sites in Japan. 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 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?

Yes. Results are posted in the registry (first posted 13 Apr 2010). 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 From Baseline at Week 12 in Average Pain Severity Rating Using Diaries for the Combined Duloxetine Arms (40 mg + 60 mg) (time frame: Baseline, 12 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 13 Apr 2010.
