What is being measured

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

  1. Change in Mean Numerical Rating Scale (NRS) Score From Baseline to Last 5 Days of Treatment

    Change of mean pain intensity from 5-day baseline to the last 5 days of treatment, measured twice daily with NRS (12 hours recall).

    Mean pain intensity for 5-day baseline period (evening Day -6 to moning Day-1) and mean pain intensity for last 5 days on treatment (ie, last dose day and the 4 preceding calendar days) was calculated based on the numerical rating scale (NRS)(0-10). 0=No pain, 10=Worst pain imaginable.

    Measured: From baseline to day 28

Secondary outcomes (8)
  1. Daily Numerical Rating Scale (NRS) Pain Scores and Change From Baseline Over Time to Day 28.

    Mean pain intensity per day (mean of morning and evening NRS values) and change from baseline were calculated for each study day. Baseline value= mean pain intensity for the 5-day baseline period. NRS scale (0- 10) where 0= No pain and 10= Worst pain imaginable.

    Measured: From baseline to 28 days

  2. Number of Patients With >=30% Reduction From Baseline in Numerical Rating Scale (NRS) Pain Intensity Score at Day 28

    Pain intensity score reduction=(change from baseline at D28/baseline)*100 Responder= pain intensity score reduction ≥30% (yes/no)? Responder rate= (no. of responders/total no. of patients)*100

    Measured: 28 days

  3. Number of Patients With >=50% Reduction From Baseline in Numerical Rating Scale (NRS) Pain Intensity Score at Day 28

    Pain intensity score reduction= (change from baseline D28/baseline)*100 Responder=pain intensity score reduction ≥50% (Yes/No)? Responder rate= (no. of responders/total no. of patients)*100

    Measured: 28 days

  4. Number of Patients With Patient Global Impression of Change (PGIC) Score of at Least "Much Improved" at Day 28.

    Patient Global Impression of Change (PGIC) scale ranges from 1-7, where 1= Very much improved and 7= Very much worse.

    Responder= Patient with a response of "much improved" or "very much improved" Responder rate= (no. of responders/total no. of patients)*100

    Measured: 28 days

  5. Change in McGill Pain Questionnaire Short Form (MPQ-SF) Sensory Index From Baseline to Day 28.

    Sensory index= sum of the intensity scale values of the words chosen for the descriptors 1-11 in the questionnaire. Range of scores for the sensory index= 0-33 (higher score represents a worse condition).

    Change from baseline (measured prior to randomization) to Day 28 was calculated.

    Measured: From baseline to day 28.

  6. Change in McGill Pain Questionnaire Short Form (MPQ-SF) Affective Index From Baseline to Day 28.

    Affective index= sum of the intensity scale values of the words chosen for the descriptors 12-15 in the questionnaire. Range of scores for the affective index=0-12 (higher score represents a worse condition).

    Change from baseline (measured prior to randomization) to Day 28 was calculated.

    Measured: From baseline to day 28.

  7. Change in Brief Pain Inventory-Short Form (BPI-SF) Pain Severity From Baseline to Day 28.

    Change from baseline (measured prior to randomization) to Day 28 was calculated for the pain severity (mean of 4 intensity items). Each intensity item is recorded on a Numerical rating Scale (NRS) 0-10, where 0=No pain and 10= The worst pain.

    Measured: From baseline to day 28..

  8. Change in Brief Pain Inventory-Short Form (BPI-SF) Pain Interference From Baseline to Day 28.

    Change from baseline (measured prior to randomization) to Day 28 was calculated for pain interference (mean of 7 interference items). Each interference item is recorded on a Numerical Rating Scale (NRS 0-10), where 0= No interference and 10= Interferes completely.

    Measured: From baseline to 28 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AZD2066 in people with Pain and Diabetic Neuropathy, run by AstraZeneca at 19 sites 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 3 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 12 Nov 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 19 sites 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 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?

Yes. Results are posted in the registry (first posted 29 Oct 2012). 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 Mean Numerical Rating Scale (NRS) Score From Baseline to Last 5 Days of Treatment (time frame: From baseline to day 28). 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 12 Nov 2012.
