Presence of multiple traditional and nontraditional risk factors of atherosclerosis and
cardiovascular disease (CVD) including inflammation in patients with chronic kidney disease
(CKD) contribute to high CVD morbidity and mortality in this patient population.
Additionally, the traditional approaches towards the therapy of CVD have little impact on CV
mortality in these patients. Hydroxychloroquine (HCQ) used as anti-inflammatory in
rheumatological disorders, has multiple beneficial properties relevant to the process of
vascular disease. The effects of HCQ on atherosclerosis (AS) and vascular disease in CKD is
not known yet. Thus, the study hypothesis is that HCQ treatment in individuals with CKD will
provide clinically significant benefit in the management of CVD and will provide biological
and functional atherosclerotic benefits.

This pilot study has been designed to look at the impact of hydroxychloroquine (HCQ) in the
clinical model of accelerated atherosclerosis (AS) in the CKD population. This intervention
is designed to have an impact on the initiation and progression of AS by reducing systemic
inflammation, improving or restoring vascular endothelial function, and by improving the
milieu of metabolic syndrome and insulin resistance.

The current study is a proof of concept study for the expansion of the use of HCQ for a new
indication for the treatment of AS and CVD in patients with CKD. UAMS has filed an IND for a
new indication on 4/28/11. The FDA responded that this study is exempt from an IND.

This "Proof-of-Concept" randomized double blinded placebo controlled study will evaluate the
nature and extent of HCQ effects, and if found significantly beneficial, it will be used to
guide the development of a large, multicenter, randomized control trial of HCQ to examine
the hard clinical end points of CVD and mortality in patients with advanced CKD. The
investigators propose to enroll 62 subjects to achieve the effects of HCQ in 52 individuals
(39 HCQ group and 13 placebo group).

Inclusion Criteria:

- Measured stage IV proteinuric CKD with an estimated MDRD GFR (eGFR) of 18 to 35

being anti-coagulated greater than 1.4.

- Known chronic active infections like HIV, Hepatitis B or Hepatitis C positive,
chronic osteomyelitis etc.

- Recent serious infection including Pneumonia requiring hospitalization, meningitis,
septicemia in the 2 months prior to screening.

- Life expectancy less than 6 months or uncontrolled congestive heart failure (CHF)
(defined as more than 2 admissions in prior 6 months).

- Any other condition the PI determines may put the research subject in jeopardy during
the course of the study.
