E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The aim or primary objective of the study is to determine whether ARA 290 administered at a daily dose of 4mg subcutaneously for 12 weeks to patients with diabetes mellitus (DM) and DMO will have a beneficial effect on mean change in best corrected visual acuity (BCVA) from baseline values to week 12. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are to determine whether ARA 290 administered at a daily dose of 4mg subcutaneously for 12 weeks to patients with DM and DMO can improve vision (as determined by the % of participants with a ≥ 10 and ≥ 15 Early Treatment Diabetic Retinopathy Study (ETDRS) letter gain), reduce central subfield thickness, increase central retinal sensitivity, increase tear production and improve retinal perfusion and quality of life with no deleterious side effects. The effects of ARA 290 on the systemic and metabolic control of participants will be also evaluated in an exploratory manner. ARA 290 antibodies will be determined as, if they were to develop in people undergoing this treatment they could have an impact on the potential subsequent response to it.

|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Patients with diabetic retinopathy and centre involving DMO with a central subfield thickness of > or equal to 400 microns, as determined using SD-OCT; 2. >= 18 years of age 3. Clear media and naïve to previous treatments for DMO.
|
|
E.4 | Principal exclusion criteria |
1. Macular oedema related to other retinal disease 2. Hazy media that prevents adequate retinal imaging 3. Allergy to fluorescein 4. Previous treatments for DMO 5. DMO with central subfield thickness of < 400 microns 6. Patients on systemic or topical steroids 7. Use of erythropoiesis stimulating agents within the two months prior to screening or during the trial 8. Treated with any other investigational medication or device within 60 days 9. Pregnant women, women who have not yet reached the menopause (no menses for ≥ 12 months without an alternative medical cause) who test positive for pregnancy, are unwilling to take a pregnancy test prior to trial entry or are unwilling to undertake adequate precautions to prevent pregnancy for the duration of the trial. 10. Female patients who are breastfeeding 11. Active proliferative diabetic retinopathy (PDR) requiring treatment. 12. Patients with other eye diseases besides diabetic retinopathy 13. Patients who are unable or unwilling to commit to the study schedule of events 14. Serious illness that is likely to affect the patient's ability to complete the study
Any patient showing improvement between the initial screening and presenting for the first screening/baseline visit will no longer be eligible for the study, will be recorded as a screen failure and will not be entered on to the study.

E.5 End points |
E.5.1 | Primary end point(s) |
Change from baseline to week 12 (+/– 7 days) in best corrected distance visual acuity |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Best corrected distance visual acuity will be obtained in both eyes by a trained optometrist using the Early Treatment Diabetic Retinopathy Study (ETDRS) charts at baseline and at weeks 4, 8 and 12. If at week 12 the retina is dry, a further visit at week 16 will be undertaken and BCVA will be obtained at this visit. The EDTRS total score will be recorded and used for the analysis. |
|
E.5.2 | Secondary end point(s) |
Changes from baseline to week 12 (+/– 7 days) in:
1. Central subfield thickness 2. Central retinal sensitivity 3. Retinal perfusion 4. Tear production 5. Patient reported outcomes 6. ARA 290 antibodies 7. Adverse events
% of participants with ≥ 10 ETDRS letter gain % of participants with ≥ 15 ETDRS letter gain
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Central subfield thickness: baseline, weeks 4, 8 and 12 (and week 16 if the retina is dry at week 12) Central retinal sensitivity: baseline and week 12 (and week 16 if the retina is dry at week 12) Retinal perfusion: baseline and week 12 Tear production: baseline and week 12 (and week 16 if the retina is dry at week 12) Visual acuity; % of participants with ≥ 10 and ≥ 15 ETDRS letter gain: week 12 (and week 16 if the retina is dry at week 12) Patient reported outcomes: EQ-5D-5L and NEI-VFQ_25 at baseline and week 12 (and week 16 if applicable). C-SSRS at baseline and weeks 4, 8 and 12 (and week 16 if applicable) Inflammatory markers: baseline and week 12. ARA 290 antibodies: baseline and week 12 AEs: Tel: 2 weeks after first & 4 weeks after last visit. Each 4 week clinic visit. |
