Abstract
Aims
The objective of this study was to demonstrate that sustained-release (SR) pregabalin is non-inferior to immediate-release (IR) pregabalin in attenuating diabetic peripheral neuropathic (DPN) pain along with patient satisfaction and compliance.
Methods
This was an 8-week, randomized, active-controlled, open-label, phase 4 study. Eligible subjects who had been on IR pregabalin for 4 weeks were randomized to 1:1 ratio to either continue with twice-daily IR pregabalin (75 mg), or to switch to once-daily SR pregabalin (150 mg). Primary efficacy endpoint was the change in visual analogue scale (VAS) scores after 8 weeks of treatment compared to baseline in both SR and IR pregabalin groups.
Results
Among 130 randomized subjects, 125 patients were included in full analysis set. For the change in VAS pain score, the least squares (LS) mean were −17.95 (SR pregabalin) and −18.74 (IR pregabalin) and the LS mean difference between both groups was 0.79, with the upper limit of the 95 % confidence interval [−5.99, 7.58] below the pre-specified non-inferiority margin of 9.2 mm.
Conclusions
This study demonstrates that the new once-daily SR pregabalin formulation is not different to the twice-daily IR pregabalin in alleviating DPN pain, indicating its potential as a promising treatment for DPN pain with a comparable safety profile.
期刊介绍:
Journal of Diabetes and Its Complications (JDC) is a journal for health care practitioners and researchers, that publishes original research about the pathogenesis, diagnosis and management of diabetes mellitus and its complications. JDC also publishes articles on physiological and molecular aspects of glucose homeostasis.
The primary purpose of JDC is to act as a source of information usable by diabetes practitioners and researchers to increase their knowledge about mechanisms of diabetes and complications development, and promote better management of people with diabetes who are at risk for those complications.
Manuscripts submitted to JDC can report any aspect of basic, translational or clinical research as well as epidemiology. Topics can range broadly from early prediabetes to late-stage complicated diabetes. Topics relevant to basic/translational reports include pancreatic islet dysfunction and insulin resistance, altered adipose tissue function in diabetes, altered neuronal control of glucose homeostasis and mechanisms of drug action. Topics relevant to diabetic complications include diabetic retinopathy, neuropathy and nephropathy; peripheral vascular disease and coronary heart disease; gastrointestinal disorders, renal failure and impotence; and hypertension and hyperlipidemia.
