Inclusion Criteria

Eligibility criteria for the main study:
1) Men or non-pregnant women (on acceptable contraception) with T1D* according to standard criteria:
*T1D defined as either (1) T1D diagnosed below 40 years of age and insulin therapy commencing within one year of T1D diagnosis, or (2) T1D diagnosed before, at or after 40 years of age along with:
i) Documented history of ketoacidosis, and/or
ii) Documented history of very low or undetectable C-peptide (fasting <200 nmol/L or 0.2 pmol/L), and/or
iii) Documented history of T1D related autoantibody/ies (anti-GAD, anti-A2, anti-ZnT8).

2) Age 18 years or over;
3) eGFR must exceed 30 ml/min/1.73m2;
4) Must have at least one eligible eye with non-proliferative retinopathy (ETDRS score 35-53 inclusive) confirmed by current retinal photography within the last 3 months (irrespective of prior laser therapy). Note: Any eye having undergone prior pan-retinal laser therapy is not eligible, but prior focal, macular or grid laser does not exclude that eye from eligibility.;
5) All types of insulin therapy, with no restriction by level of HbA1c;
6) Willing and able to comply with all study requirements, including treatment, assessment and clinic visit attendances;
7) Able to personally read and understand the Participant Information and Consent Form and provide written, signed and dated informed consent to participate in the study.

Eligibility criteria for the reference group is limited to age and gender matched individuals who do not have T1D.

Exclusion Criteria

1) Definite indication for or contraindications to fibrate treatment (Other lipid drugs [e.g. statins, ezetimibe, fish oils] are allowed.);
2) Need for bilateral intra-ocular treatment or laser photocoagulation therapy within the next 3 months (this exclusion only applies to retinal laser photocoagulation treatment to the posterior pole i.e. laser correction of corneas for short-sightedness is NOT an exclusion criterion);
3) Prior bilateral pan-retinal photocoagulation (PRP) treatment for diabetic retinopathy;
4) Prior bilateral intra-ocular injection(s) within the last 6 months;
5) Bilateral cataract surgery within the last 6 months;
6) Planned bilateral cataract surgery within the next 12 months;
7) History of any other non-diabetic eye disease that is or is likely to affect bilateral vision;
8) History of photosensitive skin rash or myositis;
9) Abnormal thyroid function (untreated);
10) Liver function tests exceeding 3xULN;
11) Persistent elevated unexplained blood CPK level above normal range;
12) Documented fasting TG levels >6.5 mmol/L;
13) History of pancreatitis, DVT or pulmonary embolism;
14) Use of investigational drugs in the prior 8 weeks;
15) Any unstable condition in last 3 months including active sepsis, diabetic ketoacidosis;
16) MI, unstable angina, stroke or heart failure within last 6 months;
17) Diagnosed cancer with ongoing treatment or prognosis anticipated at <5 years;
18) Any obstacle to regular follow-up including scheduled clinic attendances;
19) Prior or planned organ transplantation (including islet cells) with subsequent continued immunosuppression therapy.

Primary Outcome Measures

Name	Time	Method
Occurrence of clinical significant retinopathy progression: this is a composite outcome of 2-step progression of ETDRS score (using retinal photography to at least moderately severe grade), or clinically significant macular oedema, or need for laser surgery, or need for intraocular anti-VEGF or corticosteroid therapy or vitrectomy, (reported by site investigator) adjudicated to be for diabetic retinopathy (DR)[ As reported throughout the study and/or annual eye assessment with retinal photography completed 12 monthly for average of 3 years post-randomisation]
