A Quantitative Study to Assess the Construct Validity of the Prescription

Status Completed

Clinical Trial Summary

The purposes of this study are to evaluate the validity and reproducibility of the POMAQ to identify opioid abuse and misuse behaviors among participants who have chronic pain which requires long-term opioid use.

Clinical Trial Description

The Food and Drug Administration (FDA) has requested, as part of a Post-marketing requirement (PMR) for new drug application (NDA) holders of extended release/long-acting (ER/LA) opioids, to conduct a study to develop and validate a measure of the opioid-related adverse events misuse and abuse among patients with chronic pain prescribed long-term opioid therapy. This measure will be used to assess misuse and abuse in PMR Study 2065-1A and PMR Study 2065-4B.

To date, no tool currently exists to address the needs of the PMR except for the Self-Report Misuse, Abuse and Diversion of Prescription (Rx) Opioids questionnaire (SR-MAD) which has undergone several rounds of content validation but requires further validation. The SR-MAD has been substantially modified to meet the needs of PMR Studies 2065-1A and 2065-4B and has been renamed the Prescription Opioid Misuse and Abuse Questionnaire (POMAQ). The POMAQ will undergo content validation via qualitative interviews (Protocol 2065-2A [Qualitative]) prior to use in this validation study (Protocol 2065-2A [Quantitative]).

This quantitative study will seek to further develop and validate the POMAQ following the general tenants according to the Food and Drug Administration (FDA) Guidance for Industry, Patient-Reported Outcome Measures: Use in Medical Product Development to Support Labeling Claims (FDA 2009) which emphasizes the importance of conducting sound psychometric evaluation of patient-reported instruments through quantitative research methods. However, it should be noted that the POMAQ is not a typical PRO measure capturing a specific latent construct and the specified analytic approach to the POMAQ reflects this difference in theoretical frameworks. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
