Evaluation of AGN-150998 in Exudative Age-related Macular Degeneration (AMD)

April 9, 2019 updated by: Allergan
This study is conducted in 3 stages. Stage 1 is an open-label, dose-escalation assessment of the safety of AGN-150998 administered as a single intravitreal injection to patients with advanced exudative Age-related Macular Degeneration (AMD). Stage 2 and Stage 3 are randomized, double-masked, comparisons of the safety and treatment effects on retinal edema and best-corrected visual acuity (BCVA) of AGN-150998 and ranibizumab in treatment-naive patients with exudative AMD. Study medication is administered as needed in Stage 2 and with a fixed-dosing schedule in Stage 3. The study objectives are (1) to identify the highest tolerated dose of AGN-150998, (2) to assess the safety and duration of treatment effects on retinal edema and BCVA, and (3) to characterize the systemic pharmacokinetic profile of AGN-150998.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Highest Tolerated Dose (HTD) of AGN-150998
Time Frame: 24 Weeks
Stage 1 evaluated the safety of a single intravitreal injection of AGN-150998 with doses ranging from 1.0 to 4.2 mg.
24 Weeks
Stage 1: Change From Baseline in Central Retinal Thickness (CRT) in the Study Eye
Time Frame: Baseline, Week 4
CRT was assessed using spectral domain optical coherence tomography (SD-OCT), a non-invasive diagnostic system providing high-resolution imaging sections of the retina. SD-OCT was performed in the study eye after pupil dilation. A negative change from Baseline indicated improvement.
Baseline, Week 4
Stage 2: Time Between Baseline Treatment and Recurrence of Active Disease
Time Frame: Baseline, Week 16
Recurrence of Active Disease was based on Best Corrected Visual Acuity (BCVA), Central Retinal Thickness (CRT) values as evaluated by the Central Reading Center (CRC) and the investigator assessments of haemorrhage.
Baseline, Week 16
Stage 3: Change From Baseline in Best Corrected Visual Acuity (BCVA) in the Study Eye
Time Frame: Baseline, Week 16
BCVA is measured using an eye chart and is reported as the number of letters read correctly (ranging from 0 to 100 letters) in the study eye. The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). An increase in the number of letters read correctly means that vision has improved.
Baseline, Week 16

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Stage 2: Time Between Second Treatment and Recurrence of Active Disease
Time Frame: 32 Weeks
Recurrence of active disease is defined as the time in days to escape to standard of care. Time is calculated as (date of Escaping to Standard of Care/Censoring minus the date of the Second Injection) +1.
32 Weeks
Stage 2: Change From Baseline in Central Retinal Thickness (CRT) in the Study Eye
Time Frame: Baseline, Week 4
CRT was assessed using spectral domain optical coherence tomography (SD-OCT), a non-invasive diagnostic system providing high-resolution imaging sections of the retina. SD-OCT was performed in the study eye after pupil dilation. A negative change from Baseline indicated improvement.
Baseline, Week 4
Stage 2: Change From Baseline in Best Corrected Visual Acuity (BCVA) in the Study Eye
Time Frame: Baseline, Week 4
BCVA is measured using an eye chart and is reported as the number of letters read correctly (ranging from 0 to 100 letters) in the study eye. The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). An increase in the number of letters read correctly means that vision has improved.
Baseline, Week 4
Stage 3: Change From Baseline in Central Retinal Thickness (CRT) in the Study Eye
Time Frame: Baseline, Week 4
CRT was assessed using spectral domain optical coherence tomography (SD-OCT), a non-invasive diagnostic system providing high-resolution imaging sections of the retina. SD-OCT was performed in the study eye after pupil dilation. A negative change from Baseline indicated improvement.
Baseline, Week 4
Stage 3: Change From Baseline in BCVA in the Study Eye
Time Frame: Baseline, Week 4
BCVA is measured using an eye chart and is reported as the number of letters read correctly (ranging from 0 to 100 letters) in the study eye. The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). An increase in the number of letters read correctly means that vision has improved.

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
