简要总结

This study was designed to evaluate the efficacy and safety of two different dosing regimens of 0.5 mg ranibizumab given as intravitreal injection in comparison to verteporfin PDT in patients with visual impairment due to choroidal neovascularization secondary to pathologic myopia (PM)

详细描述

This was a phase III, multi-center, randomized, double-masked, active-controlled study comparing 0.5 mg ranibizumab vs. vPDT therapy. The study included 15 scheduled visits over 12 months, and there were to be two additional visits (2a, 3a) for subset of patients in whom PK analysis were performed.

There were 3 periods in this study: Screening period-from Day -14 to Baseline; Treatment period-from Baseline to Month 11; Follow-up period-from Month 11 to Month 12 Patients entered the 11 months Treatment period at Visit 2 (Day 1) if eligibility criteria were met and were randomized in three treatment groups Group I ranibizumab 0.5 mg driven by VA stability criteria or Group II ranibizumab 0.5 mg driven by disease activity criteria or Group III vPDT (randomization ratio of 2:2:1) and received first treatment of either a ranibizumab injection and sham vPDT or sham injection and active vPDT and will return to the clinical center within 7 days to undergo safety assessments as well as assessments of the effect of treatment by the evaluating investigator. The following visits were performed at one month intervals starting at Visit 4 and continuing through Visit 14. At all monthly visits (at/from Month 2 for group I, at/from Month 1 for group II and at/from Month 3 for group III) the decision for treatment were made by the evaluating investigator based on the VA stability criteria and on the disease activity criteria. At Month 3 (visit 6) and at all following monthly visits for all three groups one of the three options can recommended by evaluating investigator: a) ranibizumab 0.5 mg, b) ranibizumab 0.5 mg + vPDT; c) vPDT. The treating investigator were then perform treatment based on randomization and masking requirements.

At each monthly visit, patients had a safety evaluation by the evaluating investigator prior to study treatment, consisting of visual acuity measurements, ophthalmic examinations and evaluation of adverse events and vital signs. Routine hematology, chemistry, and urinalysis profiles were obtained at Visit 6, 9 and 12 (Month 3, 6 and 9). At Month 12 several procedures and assessments were performed which are required at study completion visit.

结局指标

主要结局

Change From Baseline BCVA to the Average Level of BCVA Over All Monthly Assessments From Month 1 to Month 3

时间窗: From Baseline to Month 3

Best corrected visual acuity (BCVA) was tested using the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity (VA) charts testing protocol. VA measurements were taken in a sitting position at an initial test distance of 4 meters using ETDRS charts. The overall BCVA score was calculated using the BCVA worksheet, which was kept in the source data and the score was recorded in the eCRF.

次要结局

  • The Average Change in BCVA Score From Baseline to Month 1 Through Month 12(From Baseline to Month 12)
  • Mean Change From Baseline in Visual Acuity Over Time(Change from baseline at months 3, 6, and 12)
  • NEI-VFQ-25 - Change From Baseline to Month 3, 6 and 12(Change from baseline at month 3, 6 and 12)
  • Number of Patients With CNV Leakage (Center Involvement) in the Study Eye at Baseline and Month 12(From Baseline until Month 12)
  • Change From Baseline BCVA to the Average Level of BCVA Over All Monthly Assessments From Month 1 to Month 6(From Baseline to Month 6)
  • Categorized BCVA Changes at Months 3, 6 and 12 Compared With Baseline for the Study Eye(From Baseline to Month 12)
  • Mean Change From Baseline Over Time in Central Sub-field Thickness (CSFT)(Baseline, Month 3, Month 6, and Month 12)
  • Number of Ranibizumab Injections Received in the Study Eye for the Ranibizumab Groups(From Baseline to Month 12)
