Descriptive Information

• Brief Title: Comparing the Efficacy and Safety of Biosimilar Candidate Xlucane Versus Lucentis® in Patients With nAMD
• Official Title: A Phase III Double-Blind, Parallel Group, Multicenter Study to Compare the Efficacy and Safety of Xlucane Versus Lucentis® in Patients With Neovascular Age-Related Macular Degeneration
• Brief Summary: The objectives of the study are to demonstrate the equivalence of Xlucane to Lucentis® in treatment of subjects with wet (ie, neovascular) age-related macular degeneration (wAMD).
• Detailed Description: This is a phase III multicenter, double-masked, randomized, parallel group study in subjects with wAMD. Approximately 580 subjects will be enrolled and randomized in a 1:1 ratio to receive either Lucentis® or the investigational product, Xlucane in the study eye once every 4 weeks for 52 weeks. The study eye will be defined as the eye meeting the enrollment criteria. The assigned study drug will be administered as an ophthalmic intravitreal (IVT) injection. A subgroup of 60 subjects at a select number of participating sites will be sequentially asked to participate in an evaluation of PK.
• Study Type: Interventional
• Study Phase: Phase 3
• Study Design: Allocation: Randomized; Intervention Model: Parallel Assignment; Masking: Double (Participant, Outcomes Assessor); Primary Purpose: Treatment
• Condition: Macular Degeneration

Intravitreal injection

Study Arms

• Experimental: Xlucane
  Xlucane (0.05 mL of 10 mg/mL ranibizumab) in the study eye monthly for 52 weeks.

Eligibility Criteria

Inclusion Criteria:

• Written and signed informed consent form obtained at screening, before any study-related procedures.
• Willingness and ability to undertake all scheduled visits and assessments as judged by the investigator.

• Newly diagnosed, active subfoveal Choroidal Neovascularization (CNV) lesion secondary to age-related macular degeneration (AMD) in the study eye. Note: Active CNV indicates the presence of leakage as evidenced by Fluorescein Angiography (FA) and intra- or subretinal fluid as evidenced by Optical Coherence Tomography (OCT) which must be confirmed by the central reading center during Screening:

  1. The area of CNV must be ≥ 50% of the total lesion area in the study eye, and
  2. Total lesion area ≤ 9.0 Disc Areas (DA) in size (including blood, scars and neovascularization) as assessed by FA in the study eye.
• Best Corrected Visual Acuity (BCVA) of ≤ 73 and ≥ 49 ETDRS letter score in the study eye, using ETDRS chart (20/40 to 20/100 Snellen equivalent) at Screening.
• Fellow eye should not be expected to need any anti-VEGF treatment for the duration of study participation.
• Age ≥ 50 years at screening.
• Male and female subjects of childbearing potential must be willing to completely abstain or agree to use an appropriate method of contraception, from the time of signing informed consent and for the duration of study participation through 3 months, following the last dose of study drug.

Exclusion Criteria:

• Any previous intervention including pharmacological treatment, laser and/or surgery for wAMD in either eye; (Exception: Vitamin supplementation for AMD prevention).
• Any previous vitreoretinal surgery in the study eye for any cause.

• Active or recent (within 28 days prior to randomization) intraocular, extraocular, and periocular inflammation or infection in either eye.
• History of idiopathic or autoimmune-associated uveitis in either eye.
• Infectious conjunctivitis, keratitis, scleritis or endophthalmitis in either eye.

• Current vitreous hemorrhage in the study eye.
• Subretinal hemorrhage that is ≥ 50% of the total lesion area in the study eye, or if the subretinal hemorrhage involves the fovea is 1 or more DA (≥ 2.54 mm2) in size in the study eye, as assessed by FA and confirmed by the central reading center.
• Other intraocular surgery (including cataract surgery) in the study eye within the 3 months prior to baseline. The yttrium aluminum garnet [YAG] posterior capsulotomy is allowed not later than 4 weeks prior to screening.
• Any concurrent intraocular condition in the study eye (eg, cataract or diabetic retinopathy) that, in the opinion of the investigator, could require treatment during the study period to prevent or treat loss of visual acuity.
• Significant media opacities (including cataract) in the study eye interfering with BCVA assessment or fundus imaging (FA/FP/OCT).
• Aphakia or absence of the posterior capsule in the study eye, unless it occurred as a result of a YAG posterior capsulotomy in association with prior posterior chamber intraocular lens implantation.
• Presence of advanced glaucoma or optic neuropathy that involve(s) or threaten(s) the central visual field in the study eye (as judged by the investigator).
• History of glaucoma filtering surgery or argon laser trabeculoplasty in the study eye (Exception: Laser iridotomy and selective laser trabeculoplasty are allowed).
• Uncontrolled ocular glaucoma or hypertension in the study eye, defined as IOP ≥ 25 mmHg despite treatment with anti-glaucoma medication.
• Any previous systemic anti-VEGF treatment (eg, bevacizumab).
• Contraindication for Lucentis® (hypersensitivity to ranibizumab or to any of the study treatment excipients).
• Current treatment for active systemic infection.
• Females who are pregnant, nursing, planning a pregnancy during the study, or of childbearing potential and not using a reliable method of contraception and/or not willing to use a reliable method of contraception during their participation in the study.
• Participation in another clinical trial within the previous 3 months or any other clinical trial of anti-angiogenic drugs.
• Reasonable suspicion of other disease or condition that might render the subject at a high risk of treatment complications or otherwise confound interpretation of the study results (as judged by the investigator).
• PK subgroup only: Contraindication for additional blood sampling (as judged by the investigator).
