Study Comparing Ranibizumab Monotherapy With Combined Verteporfin Therapy in Subfoveal CNV

April 6, 2009 updated by: University Hospital, Basel, Switzerland

Randomized, Phase IIIb Study Comparing Safety, Tolerability and Efficacy Between Lucentis® Administered in Conjunction With PDT With Visudyne® and Lucentis® in Patients With Subfoveal CNV Secondary to Age-Related Macular Degeneration

This pilot study is designed to evaluate the safety and efficacy of intravitreal ranibizumab used in combination with verteporfin photodynamic therapy (Visudyne®) compared to ranibizumab monotherapy for the treatment of subfoveal CNV secondary to AMD

Study Overview

Detailed Description

Intravitreal ranibizumab has shown to increase average vision in patients with subfoveal CNV secondary to AMD. However, the treatment does not provide benefit to all patients and the treatment regimen requires monthly intravitreal injections. Ranibizumab is an anti-VEGF-A monoclonal antibody fragment. Verteporfin photodynamic therapy acts through occluding newly formed vessels. The combination of these therapies acting through different modes of action bears the potential to provide a more convenient and less frequent therapy while maintaining/improving the increase in vision improvement observed with ranibizumab monotherapy. The strategic goal is to evaluate whether intravitreal ranibizumab in combination with verteporfin photodynamic therapy is an effective, safe and convenient treatment for patients with subfoveal CNV secondary to AMD and explore potential advantages of such treatment compared to ranibizumab monotherapy

Description

Inclusion Criteria:

  1. patients over 50 years, subfoveal CNV of any type secondary to age-related macular degeneration (AMD), no "macula-treatment for the last 30 days (e.g. with PDT, TA, Laser, Macugen®).

    • the area of the CNV must occupy at least >50% of the lesion (total lesion size under 5400 microns in greatest linear dimension)
    • Occult CNV:

      • recent disease progression
      • bleeding
      • VA decreased the last three months >5 letters or 2 or more than two lines (Snellen)
      • 10% increase of the lesion size the last three months
  2. Best corrected visual acuity score between 24-73 letters (20/40 to 20/320) (ETDRS 4 m)

Exclusion Criteria:

  1. Prior treatment with mit Laser, PDT, Macugen, TA
  2. Prior treatment with radiatio, vitrectomy, transpupillary thermotherapy
  3. History of surgical intervention in the study eye within two months preceding day 1
  4. concurrent use of systemic anti-VEGF agents
  5. previous treatment with or participation in a clinical trial involving anti-angiogenic drugs (Pegaptanib, ranibizumab, anecortave acetate of corticosteroids).
  6. Ocular disorders in the study eye that may confound interpretation of the study results, including retinal detachment or macular hole (Stage 3 or 4), active intraocular inflammation (grade trace or above) or persistent macular edema due to uveitis or other inflammatory diseases
  7. Retinal pigment epithelium tear, vitreous hemorrhage or history of rhegmatogenous retinal detachment or macular hole in the study eye
  8. History of idiopathic or autoimmune-associated uveitis in either eye, active infectious conjunctivitis, keratitis, scleritis or endophthalmitis in either eye
  9. Extracapsular extraction of cataract with phacoemulsification within two months preceding day 1, or a history of post-operative complications within the last 12 months preceding day 1 or a history of post-operative complications within the last 12 months preceding day 1 in the study eye (uveitis, cyclitis, iritis etc.)
  10. Glaucoma with IOP>25 mmHg despite therapy
  11. Aphakia or absence of the posterior capsule in the study eye
  12. Spherical equivalent >-8
