Octreotide Acetate in Microspheres in Patients With Diabetic Retinopathy

This study has been completed.
Information provided by (Responsible Party):
Novartis Identifier:
First received: August 16, 2005
Last updated: November 16, 2011
Last verified: November 2011
The most common ocular disease in patients with diabetes, diabetic retinopathy, is present in approximately 40% of diabetic patients; about 8% of diabetic patients have vision threatening diabetic retinopathy. Although intensive control of blood glucose has been shown to reduce the development and progression of diabetic retinopathy, intensive control of glucose is usually not achieved in clinical practice.

Condition Intervention Phase
Diabetic Retinopathy Drug: Octreotide Acetate in Microspheres 20 mg Drug: Octreotide Acetate in Microspheres Drug: Placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized, Controlled Study on the Efficacy and Safety of Octreotide Acetate in Microspheres in the Therapy of Patients With Moderately Severe or Severe Non-proliferate Diabetic Retinopathy (NPDR) or Low Risk Proliferative Diabetic Retinopathy (PDR)
