  • BCVA score <34 letters in the non-study eye.
  • Known allergy or hypersensitivity to the study medication or its components.
  • Known allergy or contraindication to the use of fluorescein or povidone iodine or contraindication to pupil dilation in either eye.
  • Female patients who are pregnant, nursing, or planning a pregnancy, or who are of childbearing potential and not using a reliable means of contraception.
  • Current enrollment in an investigational drug or device study or participation in such a study within 90 days.
  • Patient has a condition or is in a situation which will interfere with the patient's ability to comply with the dosig and visit schedules and the protocol evaluations or may not suitable for this study.

5. Study Description

Brief Summary
To determine whether TLC399 (ProDex) provides an ideal, safe, long-acting, dexamethasone sodium phosphate (DSP) delivery system for the treatment of macular edema due to retinal vein occlusion (RVO).
Detailed Description
<Part 1> An open-label, sequential dose escalation part to determine the DLT of TLC399 (ProDex) in patients with macular edema due to central retinal vein occlusion (CRVO) or branch retinal vein occlusion (BRVO). The safety results should be evaluated by Safety Monitor Committee regularly every 6 months and after last patient of each cohort completes DLT observation period. The SMC would advise or give permission for further dose escalation, de-escalation, or any study design adjustment. After the study drug administration, these patients will continue to be evaluated for efficacy and safety outcomes up to a period of 12 months unless the patient is withdrawn or discontinues the study. Group R1: 0.24 mg DSP with 100 mM PL (20 µL) Group 1: 0.36 mg DSP with 100 mM PL (30 µL) Group 2: 0.6 mg DSP with 100 mM PL (50 µL) Group 3: 0.6 mg DSP with 50 mM PL (50 µL) <Part 2> An open-label, single-arm design to investigate the use of TLC399 (ProDex) in patients with macular edema due to CRVO or BRVO in one dose level selected from Part 1. The enrollment of subjects for analysis will include approximately 20 patients in total, inclusive of Part 1 and Part 2 for the selected dose group. The safety and efficacy outcomes will be assessed for up to 12 months.
