Trial Outcomes & Findings for Effects of Roflumilast on Insulin and Blood Sugar Levels in Prediabetic Overweight and Obese Individuals (NCT NCT01862029)

NCT ID: NCT01862029

Last Updated: 2018-09-04

Results Overview

Our primary outcome measure is the change in peripheral insulin sensitivity. The hyperinsulinemic euglycemic clamp procedure's M value, which was obtained before the subjects began roflumilast, was used to assess the primary outcome.

Participant Flow

Subjects who passed the telephone screening were invited to undergo further screening in the clinic. A total of 24 subjects were subsequently screened. Among these subjects, 14 subjects met the study's inclusion criteria.

Among the 14 subjects who met the inclusion criteria, 3 subjects withdrew participation prior to starting the study procedures due to expected possibility of noncompliance with the protocol schedule. Two additional subjects were withdrawn for new medical findings prior to their initiation of the study medication.

Subjects Who Took Roflumilast
Subjects with overweight/obesity and pre-diabetes were to take Roflumilast, a phosphodiesterase 4 (PDE4) inhibitor, for a total of six weeks. They were to take roflumilast 250mcg daily for the first two weeks and then, 500mcg daily for the remaining four weeks.

PRIMARY outcome

Timeframe: Baseline

Population: Subjects who underwent the clamp procedure at time point: pre- roflumilast

Our primary outcome measure is the change in peripheral insulin sensitivity. The hyperinsulinemic euglycemic clamp procedure's M value, which was obtained before the subjects began roflumilast, was used to assess the primary outcome.

PRIMARY outcome

Timeframe: 6 weeks

Population: Subjects who underwent the clamp procedure at time point: post-roflumilast

Our primary outcome measure is the change in peripheral insulin sensitivity. The hyperinsulinemic euglycemic clamp procedure's M value, which was obtained post-roflumilast, was used for this primary outcome assessment.
