简要总结
The RECOVERY trial will assess the safety and tolerability of 2 mg intravitreal aflibercept injections (IAI) given monthly (Q4WK) or every 12 weeks (Q12WK) for the treatment of retinal capillary non-perfusion (RNP) associated with proliferative diabetic retinopathy (PDR).
- Assess the safety and tolerability of IAI for the treatment of proliferative diabetic retinopathy by evaluating the incidence and severity of ocular and systemic adverse events through week 52
- Change in area of retinal capillary non-perfusion, as assessed by central reading center, from baseline through week 52
详细描述
The investigational product is intravitreal aflibercept injection, which will be supplied by Regeneron Pharmaceuticals, Inc. in sterile vials for intravitreal (IVT) injection. Vials must be used (defined as entered with needle) only once. All drug supplies are to be kept under recommended storage conditions.
The injection volume will be 50μL (0.05 mL) and will be administered to the subjects by IVT injection.
Study eyes will be assigned randomly (1:1 ratio) to one of the following 2 treatment arms:
-
Group 1- aflibercept 2 mg every 4 weeks (defined as every 28 days (+ 7 days) and at least 21 days between injections) through week 48. Subjects will have a mandatory Year 1 visit at week 48. Subjects have a mandatory visit at week 52 & will not receive treatment. During the second year of follow-up, subjects will be monitored and treated every 12 weeks (Week 60, 72, 84 and 96) with an end of study visit at week 100. If NV or PDR are worse per the pre-specified criteria at week 60, or at any study visit thereafter, the subject will be treated monthly through the end of the study.
-
Group 2 - aflibercept 2 mg every 12-weeks for 48 weeks. Subjects will be followed every 4 weeks through week 12, and can be treated if the pre-specified criteria are met. Starting at week 12 if NV or PDR are stable or improved (as assessed by investigator) the subject will be monitored and treated at a 12-week interval through week 48. If NV or PDR are worse per the pre-specified criteria at week 12, or at any study visit thereafter, the subject will be treated monthly through week 48. At week 52 -
-
For subjects without any retinal non-perfusion, monitoring and treatment will continue at every 12 weeks (Week 60, 72, 84, 96) with an end of study visit at week 100.
-
For subjects with visible retinal non-perfusion, monitoring and treatment will be at a 4-week interval (defined as every 28 days + 7 days and at least 21 days between injections). If retinal non-perfusion has completely resolved at week 72, the subject will be switched back to monitoring and treatment every 12 weeks (Week 72, 84, 96).

- •Provide signed informed consent
- •Substantial non perfusion (defined as greater than 20 disc areas), as assessed by the investigator
- •Early PDR, as assessed by the investigator, with no vitreous hemorrhage*

排除标准
- •Any prior systemic anti-VEGF (anti vascular endothelial growth factor) or IVT anti-VEGF treatment in the study eye,
- •SD-OCT (Spectral Domain Optical Coherence Tomography) central subfield thickness measurement of > 320 µm, in the study eye

- •Tractional Retinal Detachment threatening the macula in the study eye
- •Corticosteroid treatment (intravitreal or peribulbar) in the study eye within 12 weeks of screening
- •Pregnant or breast-feeding women
- •Sexually active men* or women of childbearing potential who are unwilling to practice adequate contraception during the study. Adequate contraceptive measures include stable use of oral contraceptives or other prescription pharmaceutical contraceptives for 2 or more menstrual cycles prior to screening; intrauterine device (IUD); bilateral tubal ligation; vasectomy; condom plus contraceptive sponge, foam, or jelly, or diaphragm plus contraceptive sponge, foam, or jelly.

研究组 & 干预措施
Q4WKS
Aflibercept 2 mg every 4 weeks (defined as every 28 days (+ 7 days) and at least 21 days between injections) through week 48. Following week 48, aflibercept 2 mg every 12 weeks through week 96.
If NV or PDR are worse per pre-specified criteria at week 60, or at any study visit thereafter, the subject will be treated every 4 weeks through the end of the study.
干预措施: Aflibercept (Drug)
Q12WKS
Aflibercept 2 mg every 12-weeks. Subjects will be followed every 4 weeks through week 12, and can be treated if the pre-specified criteria are met. Starting at week 12 if NV or PDR are stable or improved (as assessed by investigator) the subject will be monitored and treated at a 12-week interval through week 48. If NV or PDR are worse per the pre-specified criteria at week 12, or at any study visit thereafter, the subject will be treated monthly through the end of the study.
At week 52, aflibercept 2 mg every 4 weeks (defined as 28 days (+ 7 days) and at least 21 days between injections) for subjects with visible retinal non-perfusion.
