简要总结
Open-label Multicenter, Phase I/II Study comprising three phases (single dose, multiple dose and extension phase), Assessing the Safety and Efficacy of Ranibizumab (RFB002) in Japanese Patients With Subfoveal Choroidal Neovascularization (CNV) Secondary to Age-related Macular Degeneration (AMD).
详细描述
The safety and tolerability of single intravitreal injections of ranibizumab was evaluated in patients enrolled in the single dose phase (Group A). Patients who successfully completed the single dose phase (i.e. did not experience a grade-3 targeted adverse event) could enter the multiple dose phase and receive ranibizumab injections for an additional 11 months. Simultaneously, the multiple dose phase was initiated in two parallel dose groups of additional patients (Group B), who received ranibizumab injections for 12 months. After patients in Group A and Group B had completed the multiple dose phase, all patients who provided written consent and were considered eligible based on the inclusion and exclusion criteria of the extension phase had the opportunity to continue on study treatment with the individualized flexible treatment regimen guided by monthly acuity scores and other ophthalmic examinations until approval of ranibizumab in Japan.

研究组 & 干预措施
Group A: Ranibizumab 0.3 mg
In the single dose phase, all patients randomized in Group A received a single intravitreal injection of 0.3 mg of ranibizumab into the study eye. Those patients who successfully completed this phase entered the multiple dose phase, where they received an intravitreal injection of 0.3 mg of ranibizumab once a month for an additional 11 months. Subsequently patients enrolling in the extension phase received an intravitreal injection of 0.3 mg of ranibizumab according to an individualized flexible interval regimen guided by monthly best corrected visual acuity scores and other ophthalmic examinations. In the extension phase patients received the same dose level as they received in the multiple dose phase of the study, for an average of 1.70 years.
干预措施: Ranibizumab (Drug)
Group A: Ranibizumab 0.5 mg
In the single dose phase, all patients randomized in Group A received a single intravitreal injection of 0.5 mg of ranibizumab into the study eye. Those patients who successfully completed this phase entered the multiple dose phase, where they received an intravitreal injection of 0.5 mg of ranibizumab once a month for an additional 11 months. Subsequently Group A patients enrolling in the extension phase received an intravitreal injection of 0.5 mg of ranibizumab according to an individualized flexible interval regimen guided by monthly best corrected visual acuity scores and other ophthalmic examinations. In the extension phase patients received the same dose level as they received in the multiple dose phase of the study, for an average of 1.93 years.
干预措施: Ranibizumab (Drug)
Group B: Ranibizumab 0.3 mg
Group B patients received a total of 12 monthly intravitreal injections of 0.3 mg of ranibizumab into the study eye in the multiple dose phase of the study. Group B patients who enrolled in the extension phase received an intravitreal injection of 0.3 mg of ranibizumab according to an individualized flexible interval regimen guided by monthly best corrected visual acuity scores and other ophthalmic examinations. In the extension phase patients received the same dose level as they received in the multiple dose phase of the study, for an average of 1.45 years.
干预措施: Ranibizumab (Drug)
Group B: Ranibizumab 0.5 mg
Group B patients received a total of 12 monthly intravitreal injections of 0.5 mg of ranibizumab into the study eye in the multiple dose phase of the study. Group B patients who enrolled in the extension phase received an intravitreal injection of 0.5 mg of ranibizumab according to an individualized flexible interval regimen guided by monthly best corrected visual acuity scores and other ophthalmic examinations. In the extension phase patients received the same dose level as they received in the multiple dose phase of the study, for an average of 1.36 years.

结局指标
主要结局
Mean Change From Baseline in the Best Corrected Visual Acuity Score of the Study Eye at Month 6 in Group B
时间窗: Baseline and Month 6
The efficacy assessment was based on Group B patients. Best Corrected Visual Acuity (BCVA) was assessed during all study visits using best correction determined from protocol refraction at a starting test distance of 2 meters. VA measurements were taken in a sitting position using Early Treatment Diabetic Retinopathy Study (ETDRS)-like visual acuity testing charts at a starting test distance of 2 meters. The BCVA score is the number of letters read correctly by the patient, hence an increase in score indicates improvement in acuity.
次要结局
- Mean Change From Baseline in the Best Corrected Visual Acuity Score of the Study Eye at Month 12 in Group B(Baseline and Month 12)
- Categorical Analysis of Best Corrected Visual Acuity of the Study Eye at Month 6 and Month 12 in Group B(Baseline, Month 6 and Month 12)
- Extension Phase: Mean Change From Month 12 (Start of Extension Phase) in Best Corrected Visual Acuity Score of the Study Eye at Last Visit of Extension Phase in Group B.(Month 12 (start of extension phase) and last visit of extension phase. Duration in the extension phase varied depending on the study entry. The mean duration of treatment was 1.45 years in the 0.3 mg group and 1.36 years in the 0.5 mg dose group.)
- Extension Phase: Categorical Analysis of Best Corrected Visual Acuity of the Study Eye at Last Visit of Extension Phase in Group B(Baseline and last visit of extension phase - Duration in the extension phase varied depending on the study entry. The mean duration of treatment was 1.45 years in the 0.3 mg group and 1.36 years in the 0.5 mg dose group.)
