Fenofibrate for Prevention of DR Worsening
United States563 participantsStarted 2021-03-05
Plain-language summary
This randomized trial will evaluate the effect of fenofibrate compared with placebo for prevention of diabetic retinopathy (DR) worsening through 6 years of follow-up in eyes with mild to moderately severe non-proliferative DR (NPDR) and no CI-DME at baseline.
In addition to evaluating efficacy, this study aims to evaluate the feasibility of a model for ophthalmologists to prescribe or collaborate with a primary care provider such as an internist/endocrinologist to prescribe and monitor the drug safely. If this study demonstrates that fenofibrate is effective for reducing the onset of proliferative diabetic retinopathy (PDR) or and the results are adopted by the community of retina specialists, a new strategy to prevent vision threatening complications of diabetes could be widely adopted. Widespread use of an oral agent effective at reducing worsening of DR would decrease the numbers of patients who undergo more invasive and much more expensive treatment for DR and who are consequently at risk for side effects that adversely affect visual function. This study will also assess the relationship of glycemic variability, as measured by continuous glucose monitoring with DR outcomes. Ancillary studies will characterize functional and structural outcomes in this cohort.

Key Inclusion Criteria
* Age ≥18 years and \< 80 years.
* Type 1 or type 2 diabetes.
* At least one eye with the following:
* Mild to moderately severe NPDR (defined by ETDRS DR severity level 35 to 47), confirmed by central Reading Center grading of fundus photographs.
* Best-corrected E-ETDRS visual acuity letter score of ≥74 (approximate Snellen equivalent 20/32 or better). If best corrected letter score is 74-78, investigator must verify that vision loss is not due to the presence of CI-DME, cataract, or other condition that may affect visual acuity during the course of the study.
* If only one eye is eligible, the non-study eye must have at least microaneurysms only (DR severity level 20)
Key Exclusion Criteria
Eye-level exclusion criteria (the eye is ineligible if any of the following is met):
* Current CI-DME based on clinical exam or OCT central subfield thickness (CST)
* Zeiss Cirrus: CST ≥290 µm in women or ≥ 305 µm in men
* Heidelberg Spectralis: CST ≥305 µm in women or ≥320 µm in men
* Any prior treatment for DME or DR, other than focal/grid laser. If the eye has a history of focal/grid laser, it must be at least 12 months prior.
* History of intraocular anti-VEGF or corticosteroid treatment within the prior year for any indication
Participant-level exclusion criterion (the participant is ineligible if the following criterion is met):
• Decreased renal function, defined as requiring dialysis or central laboratory eGFR value \< 45 mL/min/1.73 m2
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
