Reduced Fluence Visudyne-Anti-VEGF-Dexamethasone In Combination for AMD Lesions (RADICAL) - Full Text View

Sponsor:	QLT Inc
Information provided by:	QLT Inc
ClinicalTrials.gov Identifier:	NCT00492284

Purpose

The objective of this study is to determine if combination therapy (reduced-fluence Visudyne followed by Lucentis [within 2 hours] or either of two regimens of reduced-fluence Visudyne followed by Lucentis-Dexamethasone triple therapy [within 2 hours]) reduces retreatment rates compared with Lucentis monotherapy while maintaining similar vision outcomes and an acceptable safety profile.

Primary Outcome Measures:

The primary efficacy variable are mean number of retreatments (Day 0 excluded) and mean change from baseline in best-corrected VA score. [ Time Frame: Month 12 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

gain = or > 15 letters; VA change = or > 0-letter gain; loss = or > 15 letters; Frequency distribution of VA change; Central retinal thickness--mean and mean change; Lesion size(GLD)--mean and mean change; adverse events, FA assessment [ Time Frame: Month 12 ] [ Designated as safety issue: No ]

Estimated Enrollment:	160
Study Start Date:	July 2007
Estimated Study Completion Date:	May 2010
Estimated Primary Completion Date:	May 2009 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
1: Experimental Reduced fluence Visudyne followed by Lucentis [within 2 hours]	Drug: verteporfin, ranibizumab Reduced-fluence Visudyne followed within 2 hours by intravitreal Lucentis 0.5 mg.
2: Experimental Reduced-fluence Visudyne followed by Lucentis-Dexamethasone triple therapy [within 2 hours]	Drug: verteporfin, ranibizumab, dexamethasone Reduced-fluence Visudyne followed within 2 hours by intravitreal Lucentis 0.5 mg and then dexamethasone 0.5 mg.
3: Experimental Very low-fluence Visudyne followed by Lucentis-Dexamethasone triple therapy [within 2 hours]	Drug: verteporfin, ranibizumab, dexamethasone Very low-fluence Visudyne followed within 2 hours by intravitreal Lucentis 0.5 mg and then dexamethasone 0.5 mg.
