Study to Collect Safety and ECG Data on Brolucizumab 6 mg Intravitreal Treatment in Patients With Wet AMD

Study Description
Brief Summary:
The purpose of this study was to collect ECG data after a single IVT injection of brolucizumab 6 mg in patients with neovascular age-related macular degeneration (nAMD).

Condition or disease Intervention/treatment Phase
Age-Related Macular Degeneration Macular Degeneration Wet Macular Degeneration Retinal Degeneration Retinal Diseases Eye Diseases Biological: brolucuzumab 6 mg IVT Phase 3

Detailed Description:
This is a single-arm, open-label, multicenter study that collected ECG data after a single IVT injection of brolucizumab 6 mg in patients with nAMD. Triplicate 12-lead ECG recording was performed at screening to determine eligibility. A second triplicate 12-lead ECG recording was collected approximately 2h prior to the brolucizumab IVT injection on Day 1. Holter ECG recording started approximately 1 h prior to the brolucizumab IVT injection and ended approximately 48h after the IVT injection. A third triplicate 12-lead ECG recording was performed after the conclusion of Holter monitoring on Day 3.

Outcome Measures
Primary Outcome Measures :
  1. Frequency of Clinically Relevant Treatment Emergent ECG Changes After Intravitreal Injection of Brolucizumab 6 mg in Patients With nAMD [ Time Frame: Baseline, Hour 20, Hour 22, Hour 24 ]
    Incidence between 20 and 24 h post-injection of clinically relevant treatment emergent changes in heart rate (HR), pulse rate (PR), QRS, and QTc (heart rate corrected QT using Fridericia's formula, QTcF) interval (ms). This is a composite endpoint capturing all 4 parameters and 3 time-points in one Outcome Measure.

Criteria

Inclusion Criteria:

  • Signed informed consent MUST be obtained prior to participation in the study

Exclusion Criteria:

  • Concomitant conditions or ocular disorders in the study eye at screening which may cause safety concerns on the judgement of the investigator
  • Any active intraocular or periocular or systemic infection or active intraocular inflammation at Baseline
  • Treatment with any ocular intravitreal injection in the study eye within the past 7 half lives prior to Baseline
  • Intraocular surgery, prior long-acting therapeutic agent, or ocular drug release device implantation (approved or investigational) in the study eye any time during the past 3 months prior to Baseline
  • Diagnosis of ECG abnormalities including:
  • Clinically significant cardiac arrhythmias, e.g., atrial fibrillation, sustained ventricular tachycardia, and clinically significant second or third degree AV block without a pacemaker
  • Familial long QT syndrome or known family history of Torsades de Pointes
  • Resting heart rate < 50 or > 90 bpm at screening
  • Resting QTcF ≥ 450 ms (male) or ≥ 460 ms (female) at screening
  • Use of concomitant medications that are classified as known risk, conditional risk or possible risk to prolong QT/QTc interval within 7 half-lives prior to Baseline
  • History of stroke (including transient ischemic attack, reversible ischemic neurological deficit, prolonged reversible ischemic neurological deficit) or myocardial infarction (ST or non-ST elevation myocardial infarction) at any time prior to baseline
  • Chronic kidney disease as determined as a CrCL at screening of < 60 ml/min/1.73 m2 as determined by the MDRD formula
  • Uncontrolled high blood pressure defined as a systolic value ≥ 140 mmHg or diastolic value ≥ 90 mmHg at screening or baseline
  • Systemic anti-VEGF therapy during the 6-month period prior to baseline
  • Electrolyte disturbances determined as out of normal range sodium, potassium or calcium serum concentrations at screening
  • Concomitant intake of long-acting muscarinic antagonist (LAMA)/ long-acting beta adrenergic (LABA) combination therapy
  • History of hypersensitivity to any of the study drugs or its excipients or to drugs of similar classes as assessed by the investigator
  • Use of systemic or ocular (including intravitreal) investigational drugs within 7 half-lives of baseline, (or within 30 days/until the expected pharmacodynamic effect has returned to baseline), whichever is longer or longer if required by local regulations (observational clinical studies solely involving over-the-counter vitamins, supplements, or diets are not exclusionary)
  • Pregnant or nursing (lactating) women
