Clinical Trial Summary

The primary objective of this clinical trial is to determine if treatment with an anti-inflammatory drug (delayed-release prednisone) improves the health-related quality of life (HRQOL) of veterans with Gulf War Illness (GWI). The primary outcome measure is a change from baseline of HRQOL with respect to physical functioning and symptoms. Secondary outcomes measures include changes from baseline levels of GWI-associated biomarkers of inflammation in peripheral blood, GWI-associated symptoms (chronic pain, fatigue, and cognitive impairment), and HRQOL with respect to mental functioning.

Description:

During Desert Shield and Desert Storm (Aug 2, 1990 to July 31,1991) 696,841 United States Military personnel were deployed to the Kuwaiti Theater of Operations. Today approximately one-third of those veterans are suffering from GWI, an unexplained chronic multi-symptom illness. Evidence of chronic inflammation in veterans with GWI has emerged from previous observational studies. The goal of this trial is to determine if reducing the GWI-associated chronic inflammation is an effective treatment for GWI. This is a randomized, two group, placebo controlled, double blind clinical trial. The treatment group will receive a low dose (2x5mg) once a day of delayed-release prednisone (Rayos) for 8 weeks. The placebo group will receive matching placebo (2x5mg) once a day for 8 weeks. The primary outcome measure for this clinical trial is a change from baseline of HRQOL with respect to physical functioning and symptoms. The secondary outcome measures include changes from baseline of peripheral blood levels of GWI-associated biomarkers of inflammation, changes from baseline of GWI-associated symptoms (chronic pain, fatigue, and cognitive impairment), and a change from baseline of HRQOL with respect to mental functioning.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline of Veterans RAND 36-Item Health Survey Physical Component Summary Score (PCS) Scores at 8 and 16 Weeks	The SF-36V is a modification of the well-established Medical Outcomes Study Short Form Health Survey (SF-36). It surveys eight concepts of health: physical functioning, role limitations because of physical problems, bodily pain, general health perceptions, energy/vitality, social functioning, role limitations due to emotional problems and mental health. From these concepts, two summary component scores are derived: a Physical Component Summary (PCS) and a Mental Component Summary (MCS).; To calculate PCS, scales are standardized with a scoring algorithm or by the scoring software. Scores are standardized and range from 0 to 100, with a US population mean of 50 points and a SD of 10 points. The PCS and the MCS have been demonstrated to have excellent psychometric properties. SF-36V PCS is a measure of HRQOL with respect to physical functioning and symptoms. Higher scores indicate better health status,	0, 8, and 16 weeks
Secondary	Change From Baseline of McGill Pain Questionnaire-short Form (MPQ) Scores at 8 and 16 Weeks	MPQ asks questions about sensory pain, affective pain, pain now, and typical pain	0, 8, and 16 weeks
Secondary	Change From Baseline of Multidimensional Fatigue Inventory (MFI) Scores at 8 and 16 Weeks	MFI asks questions about general fatigue, physical fatigue, reduced activity, reduced motivation, and mental fatigue.	0, 8, and 16 weeks
Secondary	Change From Baseline of Cognitive Failures Questionnaire (CFQ) Scores at 8 and 16 Weeks	CFQ asks questions about cognitive symptoms such as attention, concentration, and memory	0, 8, and 16 weeks
Secondary	Change From Baseline of Veterans RAND 36-Item Health Survey Mental Component Summary Score (MCS) Scores at 8 and 16 Weeks	SF-36V MCS is a measure of HRQOL with respect to mental functioning.
