ABSTRACT

Purpose: The aim of this study was to evaluate the efficacy and tolerability of, and compliance to, preservative-free (PF), fixed-combination (FC) bimatoprost 0.03%/timolol 0.5% in patients with primary open-angle glaucoma or ocular hypertension in a clinical practice setting.

Patients and methods: This open-label study observed patients switched to PF FC bimatoprost 0.03%/timolol 0.5% due to insufficient intraocular pressure (IOP) control on previous therapies. IOP was measured at baseline and at ~12 weeks. Tolerability and continuation of therapy were also assessed.

Results: A total of 1,553 patients were included in the study, and the per-protocol population comprised 1,391 patients. There were some minor deviations from protocol: some patients with no prior therapy and some who switched for reasons other than insufficient IOP control were included in the analysis. The mean IOP was reduced by 27.4%, from 22.2 mmHg to 16.1 mmHg. In subgroup analyses, the mean IOP was significantly reduced from baseline, irrespective of whether previous treatment was monotherapy or combination therapy, and preserved or PF therapy. Physicians mostly (88.1%) reported the IOP-lowering efficacy of PF FC bimatoprost 0.03%/timolol 0.5% to be as expected or better than expected. Switching to PF FC bimatoprost 0.03%/timolol 0.5% resulted in reductions from baseline in the number of patients reporting ocular symptoms. Adverse events were reported by 6.2% of patients, the most common being eye irritation (1.6%) and eye pruritus (1.0%). Physicians reported treatment compliance as better or unchanged compared with prior treatment in almost all patients (93.9%). Most patients were expected to continue PF FC bimatoprost 0.03%/timolol 0.5% after the end of the study.

Conclusion: Switching to PF FC bimatoprost 0.03%/timolol 0.5% was associated with significant IOP reductions from baseline over 12 weeks. Adverse events were uncommon, and compliance was high compared with previous therapy. PF FC bimatoprost 0.03%/timolol 0.5% may be a suitable treatment for patients with inadequately controlled IOP or who are sensitive to preservatives.

For patients with complete data at all visits, switching from a prior IOP-lowering therapy to PF FC bimatoprost 0.03%/timolol 0.5% decreased IOP from the baseline value by a mean of 6.1 mmHg (27.4%; Figure 3): mean ± SD IOP of 22.2±3.6 mmHg at baseline vs 16.1±2.9 mmHg at the final visit (n=1,321). The small number of treatment-naïve patients (n=34) included in the study experienced the largest reduction in baseline IOP at study end (11.2 mmHg, P<0.0001).
