E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Retinopathy is a well recognised complication of diabetes and is a leading cause of vision loss in this patient group. The severity of diabetic retinopathy varies, but in its most severe form (proliferative diabetic retinopathy or PDR), ocular ischaemia causes abnormal new blood vessels to grow in the retina. These fragile new vessels may bleed into the vitreous cavity. The resulting vitreous haemorrhage impairs vision and prevents further therapy. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine if a single preoperative eye injection of ranibizumab (Lucentis) can promote clearance of persistent haemorrhage in the inner cavity of the eye, and thereby avoid pars plana vitrectomy (eye surgery to remove the blood inside the eye).
|
|
E.2.2 | Secondary objectives of the trial |
Secondary outcome measures: 1.Number of patients requiring eye surgery (pars plana vitrectomy) at study end 2.Mean duration from baseline to eye surgery (primary pars plana vitrectomy) 3.Number of intraocular procedures required 4.Mean ETDRS visual acuity* 5.Mean grade of vitreous haemorrhage (Grade 0-4)** at 6 weeks after the ramibizumab (Lucentis) or Sham injection 6.Surgical complications 7.Grading of the patient's lens clarity using LOCS II***
* ETDRS is an eyechart that scores the number of letters the patient reads correctly ** The grading system for vitreous haemorrhages is a well recognised grading scale ranging from mild haemorrhage to severe haemorrhage (0 to 4). *** The eye has a lens similar to the lens in a camera. Surgery to remove diabetic vitreous haemorrhage can produce lens opacity (cataract) that impairs the vision. The lens opacities classification system version II (LOCS II) describes the degree of lens opacity, and is assessed using slit-lamp examinat |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Inclusion criteria
1. Adults (male or female over 18) with Type 1 or Type 2 diabetes mellitus 2. Grade 2-4 fundus obscuring diabetic vitreous haemorrhage of at least 2 months duration prior to screening in the study eye 3. Subjects who have elected to undergo a therapeutic pars plana vitrectomy to clear persistent diabetic vitreous haemorrhage 4. Best corrected visual acuity from 40 letters (using 4 metre ETDRS visual acuity score) to perception of light in the study eye 5. Patients able and willing to give written and witnessed informed consent.
|
|
E.4 | Principal exclusion criteria |
Exclusion criteria
1. The presence of tractional retinal elevation in the study eye, as detected by B mode ocular ultrasound or fundus biomicroscopy. 2. Other (non-diabetic) cause of vitreous haemorrhage 3. Other (non-diabetic) retinal vasculopathy in the study eye 4. Subjects who were listed for vitrectomy for recurrent vitreous haemorrhage alone, and not for persistent vitreous haemorrhage 5. Subjects whose planned vitrectomy was to have been combined with cataract surgery 6. Prior vitrectomy in the study eye 7. Visual acuity worse than 6/96 in the non study eye 8. Aphakia in the study eye 9. Pregnant (urine dipstick confirmed) or lactating women(women of childbearing potential should be advised to use appropriate contraception for three months following eye injection). 10. Those with systemic or ocular contraindications to ranibizumab therapy 11. Sickle cell disease. Those with sickle trait may be included if there is no evidence of retinopathy in the non study eye. 12. Patients who have had an intravitreal injection of any therapeutic agent in the study eye 13. Subjects with active concomitant disease in the study eye, including uveitis and infection 14. Subjects with inadequate pupil dilation in the study eye, or other cause of significantly impaired fundus view 15. Subjects with potentially visually significant cataract in the study eye 16. Subjects who have undergone intraocular surgery in the study eye at least 6 months prior to screening, with the exception of cataract surgery, which must have been at least 2 months prior to screening. 17. Subjects who have commenced medications that target haemostasis within 3 months of screening, including antithrombotic, antiplatelet and anticoagulant therapy, or who are likely to commence or alter such medications during the course of the study. Subjects who have commenced treatment with these agents at least 3 months prior to screening, and who are stable on treatment, are eligible for inclusion. 18. Current participation in another drug or device clinical trial, or participation in such a clinical trial within the last year 19. Patients unable or unwilling to give informed consent 20. Patients unable or unwilling to return for follow up over 12 months 21. Any other condition or situation that, in the opinion of the investigator, may prevent the patient from complying with the study protocol
