About this trial

This is an interventional treatment trial for Neovascular Age-related Macular Degeneration focused on measuring nAMD

Eligibility Criteria

50 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Male or female subjects with 50 years of age or older
  2. Active sub-foveal CNV lesion secondary to nAMD including juxta or extra-foveal lesions that partially affect the fovea
  3. The area of CNV must occupy at least 50% of total lesion
  4. Total lesion area ≤ 12 DA
  5. ETDRS BCVA letter score measured at screening and BSL
  6. Clear ocular media and adequate pupil dilation to permit good quality photographic imaging in study eye

Exclusion Criteria:

  1. Any previous systemic anti-VEGF treatment
  2. Any systemic treatment or therapy to treat neovascular AMD
  3. Continuous use of systemic corticosteroids
  4. Diseases that affect intravenous injection and venous blood sampling
  5. 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
  6. 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.
  7. Scar, fibrosis, RPE tear, or atrophy involving foveal center or area of fibrosis occupy ≥ 50% of total lesion area in study eye
  8. Evidence of myopia degeneration, diagnosis supported by the axial length examination in study eye
  9. History or any concurrent macular abnormality other than AMD in study eye
  10. Current vitreous hemorrhage or history of vitreous hemorrhage in study eye
  11. History of recurrent inflammation in study eye
  12. 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.
