Clinical Trial Summary

The investigators hypothesize that fibromyalgia (FM) and painful diabetic peripheral neuropathy (pDPN) patients with access restrictions on pregabalin will lead to higher healthcare resource use and cost compared to patients without such restrictions on pregabalin in a naturalistic setting. The randomization will occur at the physician level and not the patient level.

Description:

This trial was terminated prematurely on April 2, 2012, due to the inability to recruit the planned number of subjects. The decision to terminate the trial was not based on any safety or efficacy concerns.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Quantify the between-group difference (baseline to 6 mo.) in direct all-cause medical costs for patients with pDPN and FM in real-world treatment settings with a prior authorization (PA) versus no PA policy in place restricting access to		6 months
Primary	pregabalin		6 months
Primary	Evaluate the within-group differences (baseline to 6 mo.) in pain alleviation (using the 11 point numerical rating scale) in patients with pDPN and FM in real-world settings with a PA versus no PA policy in place restricting access to		6 months
Primary	pregabalin.		6 months
Secondary	Describe how pharmacologic treatment patterns for pDPN or FM differ between groups with PA and without PA in patients being treated in a naturalistic outpatient care setting, and who are followed for 6 mo.		6 months
Secondary	Describe non-pharmacologic treatment patterns in pDPN and FM patients in groups with PA versus no PA while being treated in a naturalistic outpatient care setting, and who are followed for 6 mo.		6 months
Secondary	Subset of patients who have at least 6 mo. pre-study time in the HIRD (HealthCore Integrated Research DatabaseSM) a within-group costs analysis (all cause) comparing pre-study healthcare utilization costs for the 6 mo. pre-baseline with on-study		6 months
Secondary	healthcare utilization costs (baseline to 6 mo.).		6 months
Secondary	Assess changes (baseline through 6 mo.) in other PRO measures in pDPN and FM patients subject to PA requirements for pregabalin versus those with no PA.		6 months
Secondary	Compare the within-group differences (baseline to 6 mo.) in pain alleviation (using the NRS-11 scale) between groups (PA versus no PA), by condition (pDPN or FM).		6 months
