Intravitreal Aflibercept for Neovascular Polypoidal Choroidal Vasculopathy (RIVAL Trial) (RIVAL)

Open-label, Non-randomized, Unmasked, Study of IAI in Patients Which Choroidal Neovascularization Secondary to Polypoidal Choroidal Vasculopathy (PCV)

The purpose of this study is to evaluate the safety and efficacy of intravitreal aflibercept injection (IAI) in patients with neovascular polypoidal choroidal vasculopathy.

Study Overview

• Status: Unknown
• Conditions: Neovascular Polypoidal Choroidal Vasculopathy
• Intervention / Treatment: Drug: Rescue Intravitreal Aflibercept Injection; Procedure: Rescue Therapy with PDT, Laser or Intravitreal Steroids

Detailed Description

This is an open-label, non-randomized, unmasked, study of IAI in patients with choroidal neovascularization secondary to polypoidal choroidal vasculopathy (PCV). Twenty treatment naïve and previously treated PCV eyes will be enrolled (only one study eye per patient will be enrolled). A maximum of 10 previously treated eyes will be enrolled. Consented, enrolled patients will be followed monthly. All patients will receive monthly IAI 2.0 mg intravitreally for 3 months (Baseline, Months 1 and 2), followed by mandatory IAI 2.0 mg every 2 months (Months 4, 6, 8 and 10) for 12 months. Patients can receive additional IAI treatment (Months 3, 5, 7, 9, and 11) if the re-treatment criteria are met. Starting at Month 3, patients can receive non-anti vascular endothelial growth factor (VEGF) rescue therapy (ie: Photodynamic Therapy (PDT), laser, intravitreal steroids) if the pre-defined criteria are met.

Description

Inclusion Criteria:

• Males and females ≥ 18 years of age. Females of child bearing potential will undergo urine pregnancy testing and be required to use appropriate methods of birth control
• ICG and fluorescein angiographic characteristics consistent with active, leaking PCV with subfoveal lesions and/or subfoveal hemorrhage, lipid exudates, PED or fluid

Exclusion Criteria:

• Any history of systemic Anti-VEGF therapy
• Current ocular or periocular infection
• Active intraocular inflammation
• Any comorbid condition that may decrease visual acuity
• Any patients who have had intraocular surgery within the past 30 days for any condition
• For treatment naïve patients: No prior anti-VEGF, PDT, intravitreal steroids or laser (subfoveal or non foveal)
• For previously-treated patients :
• Prior anti-VEGF (ranibizumab, bevacizumab, pegaptanib) within 30 days
• Prior IAI
• Prior PDT , transpupillary thermal therapy (TTT) or radiation within 90 days (a maximum of 3 PDTs allowed)
• Prior intravitreal steroids within 90 days
• Prior non-foveal laser within 90 days
• Prior subfoveal laser
• Patients with features of dry age-related macular degeneration such as abundant drusen and symptoms/demographic features inconsistent with the diagnosis of PCV
• Allergy to fluorescein, ICG, iodine, shellfish
• Any other condition that the investigator believes would pose a significant hazard to the patient if the investigational therapy were initiated
• Participation in another simultaneous medical investigation or trial
• History of previous subfoveal laser
• Advanced glaucoma (IOP > 25 or cup/disc ratio > 0.8)
• 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) *Contraception is not required for men with documented vasectomy. **Postmenopausal women must be amenorrheic for at least 12 months in order not to be considered of child bearing potential. Pregnancy testing and contraception are not required for women with documented hysterectomy or tubal ligation.
