Prospective observational post-marketing study of tafluprost for glaucoma and ocular hypertension: short-term efficacy and safety
Kuwayama Y; Nomura AAdvances in Therapy 2014; 31: 461-471
INTRODUCTION: This study investigated the intraocular pressure (IOP)-lowering effects and safety of tafluprost ophthalmic solution 0.0015% in actual clinical practice. METHODS: We started a mandatory prospective 2-year observational study, which collected IOP, conjunctival hyperemia score, corneal staining score, and adverse event data from glaucoma and ocular hypertension (OH) patients not previously treated with tafluprost at 2, 12, and 24 months. This report analyzes the 2-month findings. RESULTS: Of the 4,180 patients from 553 medical institutions in Japan, most patients had primary open-angle glaucoma (POAG, 38.1%) or normal-tension glaucoma (NTG, 44.2%). After 2 months of tafluprost administration, IOP was significantly reduced by 4.3 ± 5.2 mmHg in POAG, 2.4 ± 2.5 mmHg in NTG, 3.6 ± 5.3 mmHg in primary angle-closure glaucoma, 5.6 ± 7.1 mmHg in other types of glaucoma, and 5.3 ± 4.8 mmHg in OH. IOP was significantly reduced by 4.3 ± 4.0 mmHg in the naïve monotherapy group, 1.9 ± 3.5 mmHg in switching from prior treatment, and 3.7 ± 4.1 mmHg in the add-on therapy group. Among patients switched, the prostaglandin analog (PGA) latanoprost was the previous predominant drug (57.4%), followed by travoprost (13.8%). Significant IOP reductions were observed by 1.5 ± 3.4 mmHg in switching from latanoprost and 1.3 ± 3.7 mmHg in switching from travoprost. The conjunctival hyperemia score peaked at 1 month in the naïve monotherapy and add-on therapy groups, whereas it was significantly decreased in patients switched from another PGA. The corneal staining score showed no particular changes. Incidence of adverse drug reaction (ADR) was 7.70 % (322/4,180 patients), and all major ADRs involved the eyes or skin around the eyes. CONCLUSION: Tafluprost showed significant IOP-lowering effects without any safety concerns in patients with various types of glaucoma and OH in daily clinical practice and tafluprost is highly effective in any therapeutic patterns.
