Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants in the intervention arm will be asked to take one tablet of 145mg fenofibrate, once daily for 2 years. Adherence to the study drug will be monitored by drug tablet return, where the study coordinator will count the number of tablets in the bottle at the mandated study visits. Participants will be reviewed at pre-specified intervals within the 2 years of the study, and anti-VEGF (ranibizumab 0.5mg or aflibercept 2mg) or laser treatment administered in participants with clinical diabetic macular oedema (DME), according to an established protocol. Anti-VEGF injections or laser treatment are the 'standard care' for patients with clinical DME. 'Standard care' for pre-clinical DME is observation. Pre-clinical DME will be observed and only be treated if it progresses to clinical DME.

Treatment: Drugs
Comparator / control treatment
Participants in the control arm will take one placebo tablet (containing microcrystalline cellulose, colloidal silicone dioxide, sodium starch glycolate, sodium stearyl fumarate), once daily for 2 years. Participants will be reviewed at prespecified intervals within these 2 years, and anti-VEGF (ranibizumab 0.5mg or aflibercept 2mg) or laser treatment administered in participants with clinical DME according to an established protocol. Pre-clinical DME will only be treated if it progresses to clinical DME.

Placebo

Outcomes
Primary outcome [1] 300836 0
Reduction in macular oedema, measured objectively as a decrease in central macular thickness (CMT) on Spectral Domain-Optical Coherence Tomography (SD-OCT). CMT in participants on fenofibrate will be compared to the CMT of participants on placebo.
Timepoint [1] 300836 0
24 months from baseline
Secondary outcome [1] 331022 0
Number of intravitreal anti-VEGF injections or number of laser sessions needed for DME in each randomisation arm. If patients have received an anti-VEGF injection or laser therapy at a particular visit, it is entered into the patient clinic file on that day. The number of injections or laser sessions will also be recorded at each of the mandated visits on clinical research forms (CRFs).

Summary
Brief summary
This study is aimed at patients with Type 2 diabetes diagnosed with fluid retention in the back of the eye called "diabetic macular oedema" (DME), a main cause of vision impairment in diabetic eye disease. Standard treatments include anti-vascular endothelial growth factor injections or laser therapy to the affected eye. These are invasive, costly and carry significant risks including risk of blindness. This study will investigate whether fenofibrate (an oral agent shown to slow progression of diabetic retinopathy) reduces DME and thereby reduce the standard treatment interventions required. Cost-effectiveness for standard treatment versus standard treatment with fenofibrate will be compared.
