What is being measured

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

  1. Overall Summed Pain Intensity Difference (SPID)

    Participants assessed Pain Intensity (PI) using a 0-10 numeric pain rating scale (NPRS) where 0 is no pain and 10 is worst pain imaginable. PI was assessed 17 times within 24 hours after the first study dose, and immediately before any rescue medication and/or at early termination. The participant's baseline PI was subtracted from the timepoint PI, to derive a Pain Intensity Difference (PID) for each timepoint. Overall Summed Pain Intensity Difference (SPID) measures pain intensity change relative to baseline over the 24 hour period after dosing, and corresponds to the Area Under the Curve (AUC) of the PID. In this study, higher positive Overall SPID indicates better pain improvement. Overall SPID could range from -120 to 240. Two hour windowed last observation carried forward was used as applicable where PI score obtained before a rescue medication replaced PI score for each timepoint within 2 hours following rescue dose.

    Measured: 24 hours after the first dose

Secondary outcomes (5)
  1. Pain Intensity Using a Numeric Pain Rating Scale Utilizing 2-hour Windowed Last Observation Carried Forward (W2LOCF)

    10 point scale, where 0 is no pain and 10 is the worst pain imaginable; 2-hour windowed last observation carried forward (W2LOCF) utilizes "pain right now" just prior to rescue medication use and censors subsequent pain intensity values for 2 hours when calculating SPIDs

    Measured: 24 hours after the first dose

  2. Total Pain Relief

    Pain relief was assessed by participants using a 5 point scale, where 0 = none, 1 = slight, 2 = moderate, 3 = good or a lot, and 4 = complete. Pain relief was measured 17 times within 24 hours after the first study medication dose, and immediately before any rescue medication and/or at the time of early termination. Two-hour windowed last observation carried forward approach was used whereby the pain relief score obtained before a given rescue medication was carried forward to replace the pain relief scores collected at each observation timepoint within 2 hours following the rescue dose. Total pain relief (TOTPAR) had Areas Under the Curve (AUCs) calculated for each time point. The range for 24 hours post dose TOTPAR AUC was 0 to 96. Higher positive values indicate a better outcome with larger pain improvements.

    Measured: 24 hours after the first dose

  3. Pain Relief: Number and Percentage of Subjects With Perceptible and Meaningful Pain Relief

    The time to onset of first perceptible relief was defined as the post dose time at which the subject first begins to feel pain relief. The time to meaningful pain relief was defined as the post dose time at which the subject begins to feel meaningful pain relief. The assessments of perceptible and meaningful pain relief were ceased when rescue medication was taken.

    Measured: 24 hours after the first dose

  4. Patient's Global Assessment of Pain Control

    5 point scale, where 0 is poor, 1 is fair, 2 is good, 3 is very good, and 4 is excellent Responder = 2 is good, 3 is very good, and 4 is excellent, Non-responder = 1 is fair, 0 is poor, and missing values

    Measured: 24 hours after the first dose

  5. Rescue Medication Use

    Number of rescue medication doses

    Measured: 24 hours after the first dose

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing MR-107A-01 in people with Pain and Postoperative Pain, run by Mylan Inc. 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 4 inclusion and 6 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 8 Aug 2022. 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 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 8 Aug 2022). 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?

Overall Summed Pain Intensity Difference (SPID) (time frame: 24 hours after the first dose). 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 8 Aug 2022.
