The purpose of this study was to assess the safety, tolerability, and the effects of treatment on ocular outcomes following a single intravitreal administration of ESBA1008 compared with LUCENTIS® in patients with exudative age-related macular degeneration (AMD).

Condition Intervention Phase
Exudative Age-Related Macular Degeneration Biological: ESBA1008 solution Biological: Ranibizumab 0.5 mg Phase 1 Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Safety and Efficacy Study of ESBA1008 Versus LUCENTIS® for the Treatment of Exudative Age-Related Macular Degeneration

Primary Outcome Measures:
  • Change From Baseline at Month 1 in Central Subfield Thickness (CSFT) as Measured by Spectral Domain Ocular Coherence Tomography (SD-OCT) [ Time Frame: Baseline, Month 1 ]
    CSFT is a retinal thickness measurement and was measured with SD-OCT. A thickening of the retina is characteristic of wet AMD, and a reduction in CSFT may indicate an improvement in ocular health. One eye (ie, study eye) contributed to the mean.

Secondary Outcome Measures:
  • Duration of Effect Measured by the Time From Randomization to Receipt of Standard of Care as Determined by the Investigator Based on Protocol Criteria [ Time Frame: Time to event, up to Month 6 ]
    Standard of care (SOC) therapy for exudative AMD was implemented if any protocol-specified criteria relating to CSFT, best-corrected visual acuity, or clinically significant intraocular hemorrhages in the study eye were met, in the opinion of the Investigator.

Detailed Description:
This study was conducted in two parts. In Part 1, patients were initially randomized (5:2) to receive either ESBA1008 at the lowest dose (Dose A) or LUCENTIS. After Safety Committee review, a second cohort was enrolled and randomized (5:2) to the next higher dose of ESBA1008 (Dose B). Safety review and enrollment of patients into the third cohort (Dose C) and fourth cohort (Dose D) was conducted in the same manner. Part 2, the expansion period, consisted of 2 arms. In the first arm patients were randomized to receive ESBA1008 Dose C or LUCENTIS (43:44) . In the second arm, patients were randomized to ESBA1008 Doses A:B:D:Lucentis (5:30:35:9). All enrolled patients (Part 1 and Part 2) were evaluated for safety and efficacy across 13 study visits, including Screening, Randomization, and 11 post- treatment follow-up visits (Day 1 through Month 6).

Inclusion Criteria:

  • Provide written informed consent.
  • Primary subfoveal choroidal neovascularization (CNV) secondary to AMD, including predominantly classic, minimally classic or occult lesions, in the study eye.
  • New diagnosis of wet AMD or evidence of recent disease progression within the last 3 months in study eye.
