Safety Tolerability and Efficacy of Intravitreal LMG324 in the Treatment of Neovascular Age-Related Macular Degeneration
An Open-label Single Ascending Dose and Randomized Double-Masked, Ranibizumab Controlled, Safety, Tolerability, and Efficacy Study of Intravitreal LMG324 in Subjects With Neovascular Age-Related Macular Degeneration
調査の概要
詳細な説明
The study will start with a single dose ascending (SAD) phase. LMG324 will be administered on Day 1 with no further treatment until implementation of standard of care (SoC) therapy. SoC therapy is ranibizumab 0.5 mg administered per label. Dose groups will be implemented sequentially to allow for safety review between the current and subsequent dose group. All treatments will be open-label, including ranibizumab used as SoC therapy.
In the enrollment expansion phase, subjects randomized to LMG324 arm will receive a single LMG324 IVT injection on Day 1 followed by sham (fake) IVT injections until implementation of SoC therapy. After implementation, SoC therapy will be applied monthly with sham injections applied at the interim planned visits. The enrollment expansion phase may start at a selected dose level whilst the dose escalation phase is still ongoing.

説明
Inclusion Criteria:
- Must give written informed consent, be able to make the required study visits and follow instructions.
- Best corrected visual acuity (BCVA) of 34 letters (approximately 20/200 Snellen or better) in the non-study eye.
SAD population only:
- Subject's study eye must have a choroidal neovascularization (CNV) lesion due to age-related macular degeneration (AMD), either treatment naïve or previously treated, that can be expected to benefit, in the opinion of the investigator, from anti-vascular endothelial growth factor (anti-VEGF) therapy.
- Previously treated eyes must have a history of least 3 administrations of any intravitreal (IVT) anti-VEGF therapeutic for the treatment of CNV with the last injection administered ≥ 1 month prior to the planned administration of the study drug.
Enrollment expansion population only
- Subject's study eye must have untreated and active CNV lesion due to AMD.
- BCVA, between 73 - 23 letters, inclusive (approximate Snellen equivalent 20/40 - 20/320) in the study eye.
Exclusion Criteria:
SAD and enrollment expansion population
- Both eyes: any active ocular or periocular infection or active intraocular inflammation (eg, infectious blepharitis, infectious conjunctivitis, keratitis, scleritis, endophthalmitis).
- Study eye: current vitreous hemorrhage or a history of rhegmatogenous retinal detachment.
- Study eye: uncontrolled glaucoma (intraocular pressure [IOP] >25 mmHg on medication or according to Investigator's judgment).
SAD population only
- Presence of any contraindications, in the Investigator's opinion, to IVT anti-VEGF therapeutic administration.
Enrollment expansion population only
- Study eye: subject has received any approved or investigational treatment for exudative (wet) AMD other than vitamin supplements.
- Study eye: any current or history of macular or retinal disease other than exudative AMD
- Study eye: serous pigment epithelial detachment (PED) under the foveal center or retinal pigment epithelium (RPE) tear/rip.
- Study eye: any concurrent intraocular condition (eg, cataract, diabetic retinopathy) that, in the opinion of the Investigator, could either require medical or surgical intervention during the course of the study.
- Study eye: other ocular diseases that, in the opinion of the Investigator, can compromise the visual acuity
- Study eye: Surgery, as specified in the protocol.
