%X <B>OBJECTIVE: </B>To evaluate the long-term efficacy and safety of ripasudil-brimonidine fixed-dose combination (RBFC), a new intraocular pressure (IOP)-lowering medication for glaucoma and ocular hypertension (OHT).<BR><B>METHODS: </B>This prospective, multicentre (23 sites in Japan), open-label study enrolled patients with primary open-angle glaucoma (POAG), OHT or exfoliative glaucoma and assigned them to one of four combination therapy cohorts, based on previous treatment(s) received: prostaglandin (PG) analogue (Cohort 1); PG analogue and beta-adrenoceptor blocker (β-blocker) (Cohort 2); PG analogue, β-blocker and carbonic anhydrase inhibitor (Cohort 3); or other/no treatment (Cohort 4). After a ≥ 4-week screening period, eligible patients received twice-daily RBFC for 52 weeks in addition to the treatments they were already receiving. Efficacy was assessed by change in IOP from baseline through week 52. Adverse events and adverse drug reactions (ADRs) were monitored throughout.<BR><B>RESULTS: </B>In total, 179 patients from Cohort 1 (n = 48), Cohort 2 (n = 44), Cohort 3 (n = 41) and Cohort 4 (n = 46) entered the RBFC treatment period. For all cohorts, mean IOP was significantly reduced at 11:00 (2 h after instillation of RBFC) through week 52 with the changes from baseline at week 52 of - 2.7 to - 4.1 mmHg across cohorts; all p < 0.001. Common ADRs were conjunctival hyperaemia (58%), allergic conjunctivitis (18%) and blepharitis (17%), most of which were mild in severity.<BR><B>CONCLUSIONS: </B>These data demonstrated the long-term efficacy and safety of RBFC, both alone and in combination with other anti-glaucoma agents. RBFC may offer a new treatment option for the long-term management of glaucoma and OHT.<BR><B>BACKGROUND: </B>Japan Registry of Clinical Trials Identifier: jRCT2080225063.<BR><B>UNASSIGNED: </B>17 February 2020.
