Trial Outcomes & Findings for Hydroxychloroquine to Improve Insulin Sensitivity in Rheumatoid Arthritis (NCT NCT01132118)

NCT ID: NCT01132118

Last Updated: 2014-09-03

Results Overview

We will examine the effect of HCQ on the Matsuda Insulin Sensitivity Index (ISI) during the active treatment phase compared with placebo phase. ISI is based on insulin and glucose levels in a fasting state during an oral glucose tolerance test (OGTT) and is calculated as follows: ISI (Matsuda) = 10000/√ G0 X I0 X Gmean X Imean G0 - fasting plasma glucose (mg/dL) I0 - fasting plasma insulin (mIU/L) Gmean - mean plasma glucose during OGTT (mg/dL) Imean - mean plasma insulin during OGTT (mIU/L)

Participant Flow

107 potentially eligible RA patients were screened during 2010-2011. 7 subjects did not meet inclusion/exclusion criteria at screening and 63 declined participation.

37 subjects were initially consented, 7 withdrew consent before randomization. Thirty patients were randomized. Five patients withdrew consent after randomization and two patients stopped participation in the study due to non-serious adverse events.

HCQ Then Placebo
This arm of the study contains half the study population after randomization. The participants in this arm received hydroxychloroquine for 8 weeks and then crossed over to a placebo for 8 weeks. Study staff was blinded to which order they were taking the hydroxychloroquine and placebo in. Hydroxychloroquine: Hydroxychloroquine comes in 200 mg tablets and is taken orally. The dose provided will be based upon a calculation of 6.5 mg/kg (subject's weight), which is the dose range commonly used to treat rheumatoid arthritis and lupus. Dosages will be rounded to the nearest 100 mg.
