An OCT-Guided Variable Dosing Regimen With Ranibizumab for the Treatment of Neovascular AMD

June 12, 2012 updated by: Philip J. Rosenfeld, MD, PhD, University of Miami

Prospective Optical Coherence Tomography (OCT) Imaging of Patients With Neovascular AMD Treated With Intra-Ocular Ranibizumab (Lucentis) (PrONTO) Study

This study was designed to evaluate a variable dosing regimen with intravitreal ranibizumab for the treatment of patients with neovascular age-related macular degeneration (AMD) in the Prospective OCT Imaging of Patients with Neovascular AMD Treated with Intra-Ocular Ranibizumab (PrONTO) study.

Detailed Description

In this 2-year open-label, prospective, single-center, uncontrolled, investigator sponsored clinical study, neovascular AMD patients with subfoveal CNV (N=40) and a central retinal thickness of at least 300 µm as measured by optical coherence tomography (OCT) were enrolled to receive 3 consecutive monthly intravitreal injections of ranibizumab (0.5 mg). Thereafter, retreatment with ranibizumab was performed if one of the following changes were observed between visits: a loss of 5 letters in conjunction with fluid in the macula as detected by OCT, an increase in OCT central retinal thickness of at least 100 μm, new onset classic CNV, new macular hemorrhage, or persistent macular fluid following an injection of ranibizumab at the prior study visit.

Description

Inclusion Criteria:

  • Previous subfoveal focal laser photocoagulation in the study eye
  • Laser photocoagulation (juxtafoveal or extrafoveal) in the study eye within 1 month preceding day 0
  • Subfoveal fibrosis or atrophy in the study eye
  • History of vitrectomy surgery in the study eye
  • Aphakia or absence of the posterior capsule in the study eye
  • History of idiopathic or autoimmune-associated uveitis in either eye
