Primary Outcome Measures
NameTimeMethod
Main Objective: The objective of the study is to select the THR-149 dose and to assess the difference in treatment effect between THR-149 0.13mg (selected<br>dose level from Part A) and aflibercept in terms of increase in best corrected visual acuity (BCVA) from Baseline at Month 3.<br>;Primary end point(s): Mean change in BCVA ETDRS letter score from Baseline, at Month 3;Timepoint(s) of evaluation of this end point: From first administration of study treatment up to end of study;Secondary Objective: • To assess the efficacy of 3 monthly intravitreal injections of THR-149 over-time<br>• To assess the safety of 3 monthly intravitreal injections of THR-149 over-time<br>• To assess the efficacy and safety of a single flip-over injection<br>(aflibercept or THR 149) when administered 1 month after 3 monthly<br>injections of THR-149 or aflibercept
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): • Mean change in BCVA ETDRS letter score from Baseline, by study visit<br>• Mean change in CST from Baseline, based on SD-OCT, as assessed by the CRC, by study visit<br>• Incidence of systemic and ocular AEs and SAEs, from first injection up to the end of the study;Timepoint(s) of evaluation of this end point: From first administration of study treatment up to end of study
