About this trial
This is an interventional treatment trial for Neovascular Age-related Macular Degeneration focused on measuring nAMD
Eligibility Criteria
Inclusion Criteria:
- Male or female subjects with 50 years of age or older
- Active sub-foveal CNV lesion secondary to nAMD including juxta or extra-foveal lesions that partially affect the fovea
- The area of CNV must occupy at least 50% of total lesion
- Total lesion area ≤ 12 DA
- ETDRS BCVA letter score measured at screening and BSL
- Clear ocular media and adequate pupil dilation to permit good quality photographic imaging in study eye
Exclusion Criteria:
- Any previous systemic anti-VEGF treatment
- Any systemic treatment or therapy to treat neovascular AMD
- Continuous use of systemic corticosteroids
- Diseases that affect intravenous injection and venous blood sampling
- Presence of CNV due to other causes, such as ocular histoplasmosis, trauma, multifocal choroiditis, angioid streaks, history of choroidal rupture, or pathologic myopia in study eye
- History or any concurrent ocular condition which, in opinion of investigator, could either confound interpretation of efficacy and safety of IP or require medical or surgical intervention.
- Scar, fibrosis, RPE tear, or atrophy involving foveal center or area of fibrosis occupy ≥ 50% of total lesion area in study eye
- Evidence of myopia degeneration, diagnosis supported by the axial length examination in study eye
- History or any concurrent macular abnormality other than AMD in study eye
- Current vitreous hemorrhage or history of vitreous hemorrhage in study eye
- History of recurrent inflammation in study eye
- Subject having out of range laboratory values defined as:
ALT or AST > 2 x ULN, total bilirubin > 1.5 x ULN Serum creatinine > 1.5 x ULN, BUN > 2 x ULN

5. Study Description
Brief Summary
The purpose of this Phase 1 study is comprised of multiple ascending-dose component (Part 1) and high concentration component (Part 2) to evaluate the safety, tolerability, pharmacokinetics, and efficacy of AM712 in patients with neovascular age- related macular degeneration (nAMD).
Detailed Description
The Part 1 of study is a multicenter, open-label, sequentially, multiple ascending-dose study to evaluate the safety, tolerability, pharmacokinetics, and efficacy of AM712 in subjects with nAMD.
Subjects will be sequentially enrolled into different dose-level cohorts following the traditional "3+3" design until the maximally tolerated dose (MTD) or the maximally administered dose (MAD) has been reached.
The Part 2 of study is a multicenter, open-label, sequential study to evaluate the safety, tolerability, pharmacokinetics, and efficacy of AM712 in treatment-naïve patients with nAMD.
