CIBINETIDE / ARA 290 (RA10)

Diabetic retinopathy a very most common cause of sight loss in people of working age. Sight loss occurs in diabetes because of diabetic macular oedema (DMO) and/or proliferative diabetic retinopathy (PDR), both are complications of diabetes in the eye.

In DMO fluid accumulates in the macula, the area responsible for our central sight. As the fluid accumulates the sight drops. The current treatments for DMO include laser and anti VEGF drugs and steroids. Anti VEGF drugs have been very helpful in the treatment of DMO. However, anti VEGF drugs need to be given by an injection into the eye, an Ophthalmologist (eye specialist) or a specialist nurse (a nurse trained for this purpose) will need to deliver this treatment to patients with DMO in the hospital.

Furthermore, patients require injections every four weeks during the first months of treatment and long term treatment is required. Moreover, not all patients respond to anti VEGFs: In 40% of patients the sight may not improve despite these injections. Because many patients with DMO have DMO in both eyes, injections need to be given in both eyes to many patients.

Given the above facts there appeared a clear need to develop new treatments for people with DMO. ARA 290 is a drug that has marked anti-inflammatory properties and has an effect in preventing the death of cells. As inflammation is known to play a role in the occurrence of DMO, it was thought that ARA 290 could potentially be helpful in treating patients with this condition. In light of this, the Investigators carried out this study to find out if ARA 290 was effective in drying the fluid in DMO. If this treatment was successful, benefits may have included a reduction of the demands on health care services and patient benefits of: self administration of the drug at home by the patients; a reduction in hospital visits; treatment of both eyes at once, reduced risks associated with injections; a more pleasant treatment (subcutaneous injection versus an injection into the eye).
