About this study

Official title: A Multi-Center, Randomized, Double-Blind, Placebo-Controlled Trial of Flurbiprofen Tape for Treatment of Chronic Low Back Pain

The purpose of this trial is to evaluate the analgesic efficacy and safety of flurbiprofen tape for chronic low back pain (lasting greater than 3 months).

Read the detailed description

This study is a multi-center, randomized, double-blind, placebo-controlled study in patients with daily low back pain below the 12th thoracic vertebra of greater than 3 months duration. Patients also had an average daily pain score of 4 or greater on an 11-point categorical pain scale for the last 3 days of the baseline phase. The study began with a 14-day washout period of previously used pain medications. At the end of the 14-day baseline phase, patients were randomized to 1 of 4 treatments: Flurbiprofen tape applied once daily for 12 hours, Flurbiprofen tape applied once daily for 24 hours, placebo tape applied once daily for 12 hours, or placebo tape applied once daily for 24 hours. During the 7-day treatment phase, patients applied 2 treatment tapes once daily for 7 days. The tapes remained on for 12 or 24 hours of continuous treatment, depending on the treatment to which they were randomized. Patients were provided with rescue medication. After 7 days of tape treatment, patients returned to the clinic for a study exit visit.

What is being measured

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

  1. Cumulative Summed Pain Intensity Difference (SPID+)

    The primary efficacy endpoint was the cumulative summed pain intensity difference (SPID+) at Days 4 and 7 of the tape treatment phase as computed from the daily categorical pain scale score reported on the patient's daily diary during the tape treatment phase; pain was rated on an 11-point scale, where: 0 = no pain, 10 = worst pain imaginable.

    Summed pain intensity difference is the sum of the pain intensity differences (PID). PID at each post-baseline evaluation was computed as the average baseline categorical pain scale score minus the post-baseline categorical pain scale score from the daily dairy. For patients with multiple pain scores reported on a given post-baseline study day, the PID scores were averaged to compute one daily PID score for each patient.

    Measured: Days 4 and 7 of tape treatment phase

Secondary outcomes (9)
  1. Pain Intensity Difference (PID+)

    +PID = pre-treatment value at baseline - post-treatment value at day of evaluation, where: pre-treatment value at baseline = average daily pain over the last 3 days of the baseline phase (ie, average of daily averages of the categorical pain scale scores for the last 3 days of the baseline phase). Pain was rated on an 11-point scale, where: 0 = no pain, 10 = worst pain imaginable.

    A positive PID indicates a reduction in pain.

    Measured: Days 1 through 7 of tape treatment phase

  2. Average Daily Categorical Pain Scale Scores

    Patients rated their lower back pain, caused by normal activity and movement, on an 11-point categorical pain scale, where:

    0 = no pain, and 10 = worst pain imaginable. Patients rated their lower back pain every 12 hours, at any time they took medication including rescue medication for any type of pain, and if they applied or removed their treatment tapes at a time other than the scheduled time.

    Data are reported as the daily average categorical pain scale score by treatment group.

    Measured: Days 1 through 7 of tape treatment phase

  3. Percent Change From Baseline in Total Functional Rating Index (FRI)

    Patients completed the FRI, a 10-item back pain-specific measure of function questionnaire describing the condition at the time the questionnaire was completed; each item (pain intensity, sleeping, personal care, travel, etc.) was rated on a 5-point scale, where 0 = best outcome, 4 = worst outcome.

    FRI was reported as the percent change from baseline at Day 7 of the tape treatment phase, where:

    Total FRI score = sum of the 10 questions. The total FRI score ranged from 0 (best outcome) to 40 (worst outcome). Percent change = ([baseline - Day 7]/baseline)*100.

    A positive percent change indicates a favorable treatment effect.

    Measured: baseline to Day 7 of tape treatment phase

  4. Change From Baseline in Total Tender Point Examination Score

    At baseline and Day 7 of the tape treatment phase, patients had an assessment of tenderness bilaterally at the sacroiliac joint, greater trochanter of the hip, gluteus medius and minimus, and paraspinal muscles at L3-L4, L4-L5, and L5-S1. The investigator or research nurse pressed 12 specific areas of the body (6 locations, left and right sides), and patients were asked to rate the intensity of their pain at those 12 areas using an 11-point scale, where:

    0 = no pain, 10 = the worst pain the patient has ever experienced. The total tender point examination score ranged from 0 (best outcome) to 120 (worst outcome). Change from baseline = baseline - Day 7. A positive change indicates a favorable treatment effect.

    Measured: Baseline to Day 7 of tape treatment phase

  5. Patient Global Impression of Change (PGIC)

    At Day 7, patients provided their PGIC with regard to lower back pain response to treatment, using a 7-point scale, where:

    1 = very much improved, 7 = very much worse.

    Measured: Day 7

  6. Acetaminophen Used During the Tape Treatment Phase

    The percentage of patients who used rescue medication during the tape treatment phase.

    Measured: Day 1 through Day 7 of the tape treatment phase

  7. Acetaminophen Used During the Tape Treatment Phase

    The total amount (mg) of rescue medication used during the tape treatment phase.

    Measured: Day 1 through Day 7 of the tape treatment phase

  8. Percentage of Patients Who Discontinued

    The percentage of patients who discontinued the study during the tape treatment phase due to lack of efficacy.

    Measured: Days 1 through Day 7 of tape treatment phase

  9. Patient Assessment of Wearability of Therapy

    At Day 7, patients assessed the wearability of their treatment tape (ease of application, stays in place, comfortable to wear) using a 4-point scale, where:

    1 = Excellent, 4 = Poor.

    Measured: Day 7

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Flurbiprofen Tape (Arm 2) and Flurbiprofen Tape (Arm 4) in people with Chronic Low Back Pain, run by Teikoku Pharma USA, Inc. at 10 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 16 inclusion and 17 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 6 Oct 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 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 6 Oct 2016). 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?

Cumulative Summed Pain Intensity Difference (SPID+) (time frame: Days 4 and 7 of tape treatment phase). 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 6 Oct 2016.
