Modality Choice Before and After Failure for the Treatment of Painful Diabetic Neuropathy (MCPAIN)

25 août 2026 mis à jour par: Brian Callaghan, University of Michigan

Modality Choice Before and After Failure for the Treatment of Painful Diabetic Neuropathy (MCPAIN)

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.

Description du régime IPD

Full, de-identified datasets will be deposited in a PCORI-designated repository at study completion. Study team will follow all rules and regulations of the funding agency, which can be found here: https://www.pcori.org/about/governance/pcoris-policy-data-management-and-data-sharing

Délai de partage IPD

At the time of publication of the research project's primary results in a peer-reviewed journal - for at least 7 years

Critères d'accès au partage IPD

A data requestor that submits a data request will be evaluated for its overall qualifications and experience (e.g., across a proposed team of specified individuals) to achieve the stated research purpose underlying the data request. Neither PCORI nor the Awardee investigators will provide technical assistance directly to data requestors. However, either party may provide input to the repository upon request.
