Modality Choice Before and After Failure for the Treatment of Painful Diabetic Neuropathy
Modality Choice Before and After Failure for the Treatment of Painful Diabetic Neuropathy (MCPAIN)
Source: ClinicalTrials.gov · Last updated 21 Oct 2026
Brief summary (registry, in English)
The research team will perform a comparative-effectiveness sequential, multiple assignment, randomized trial in painful diabetic neuropathy (PDN) patients for 8 total months, divided into two 4-month stages. 600 participants 18+ with PDN will be enrolled in this study. The main goal is to compare the utility of three modalities (oral, topical, and behavioral) for initial PDN treatment, and to compare the utility of switching modalities versus continuing with the same modality for non-responders. Pain and discontinuation will be assessed weekly, whereas other outcomes will be assessed monthly for 8 months.
