About this study

The purpose of this study is to formulate definitions of doctor/pharmacy shopping and evaluate its association with abuse/addiction

Read the detailed description

Based on a review of the literature, the Food and Drug Administration (FDA) concluded that more data are needed regarding the serious risks of misuse, abuse, addiction, overdose, and death associated with the long-term use of extended release/long acting (ER/LA) opioid analgesics. Thus, the FDA is requiring that ER/LA opioid analgesic drug sponsors conduct post-marketing studies to assess these risks. The four observational post-marketing requirement (PMR) studies are labeled Study #2065-1, Study #2065-2, Study #2065-3, and Study #2065-4.

The objective of PMR Study #2065-4 is to define and validate "doctor/pharmacy shopping" as outcomes suggestive of misuse, abuse and/or addiction.

Study #2065-4 consists of three sub-studies, Study 4A, Study 4B, and Study 4C. In the current study (#2065 sub-study, Study 4A), the IMS® LRx database, a longitudinal pharmacy database that captures both third-party and self-pay transactions, will be linked to the PharMetrics Plus™ database, which contains provider, facility and pharmacy claims. From these databases, patients with shopping behavior will be identified and evaluated against an algorithm for abuse/addiction that will be developed and validated in PMR Study #2065-3B. Study #2065-3B will review the literature for health information suggestive of abuse/addiction in medical charts and medical claims. Then, through iterative processes that involve experts reviewing claims profiles and medical charts, text searches of medical records using natural language processing and supervised machine learning will identify and create a compilation of codes and health information with the best specificity and sensitivity to identify patients with opioid abuse/addiction. The compilation of codes and health information will be used to develop the algorithm that Study 4A will apply to define abuse/addiction. Restricting the validation of shopping behavior to only patients with diagnoses related to abuse would ignore the population with undiagnosed abuse. By supplementing ICD-9 codes with other information available on claims (e.g., addiction treatments, emergency visits) to define abuse/addiction, the measurement bias will be decreased and the estimates of the association of shopping behavior with abuse/addiction will be more valid. Categories of doctor shopping will be derived from the population distributions of the multiple variables analyzed for opioid users. The 4 categories will range from no shopping behavior (lowest level) to extensive shopping behavior (most extreme). The specifics of how the categories will be defined will be driven by the data.

What is being measured

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

  1. Numbers and proportions of patients with shopping behavior

    Measured: Retrospective review over 18 month period starting with first dispensing in 2012

  2. Sensitivity and predictive value of different levels of shopping behavior in relation with Algorithmically Identified Abuse and Addiction (AIAA)

    Measured: Retrospective review over 18 month period starting with first dispensing in 2012

Questions about this trial

What is this clinical trial studying?

An observational study of Opioid-Related Disorders and Opiate Addiction, run by Member Companies of the Opioid PMR Consortium.

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 2 inclusion and 1 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 15 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Numbers and proportions of patients with shopping behavior (time frame: Retrospective review over 18 month period starting with first dispensing in 2012). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02668549, which also lists 1 linked publication.

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 15 Apr 2020.
