Effectiveness and safety of tafluprost in primary open-angle glaucoma and ocular hypertension: a post-marketing phase IV study in China

摘要

Background Prostaglandin analogs (PGAs) are the first-line treatment for primary open-angle glaucoma (POAG) and ocular hypertension (OH). This study aimed to confirm the effectiveness and safety of Tapros (R) (0.0015% tafluprost eye drops) in Chinese patients with POAG and OH. Methods This phase IV, multicenter, non-comparative, prospective study enrolled patients with POAG and OH in China between 12/27/2017 and 04/15/2020. Patients who were treatment-naive or untreated within one month (group A) or with unreached intraocular pressure (IOP) target after previous monotherapy of other PGAs (group B) or non-PGA IOP-lowering drugs (group C) were treated with 0.0015% tafluprost for three months. The IOP reduction, response rate, and safety were observed. Results There were 165, 89, and 31 patients in groups A, B, and C, with baseline IOPs of 22.4 +/- 4.7, 21.0 +/- 3.5, and 22.5 +/- 3.2 mmHg, respectively. The least-square means and percentages of IOP reduction at 3 months for groups A, B, and C were 4.7 (19.8%), 1.6 (6.1%), and 4.6 mmHg (20.3%), respectively. A significant reduction in IOP was observed at each visit compared with baseline (all P < 0.05). At the final visit, 57.0% of the participants in group A achieved an IOP reduction of >= 20%, while 40.4% and 77.4% in groups B and C achieved an IOP reduction of >= 10%. Fifty-eight treatment-related adverse events occurred in 46 participants (15.7%), of which the most common one was conjunctival hyperemia (34/293, 11.6%). Conclusions Tafluprost showed a sustained and significant effect with tolerable adverse events in Chinese patients with POAG and OH who were treatment-naive or untreated within one month or received prior treatments with unsatisfying outcomes.
