摘要

A randomized, double-blind, placebo-controlled study was conducted to assess the effect of tafenoquine, 200 mg weekly for 6 months on ophthalmic and renal safety. This trial was carried out after observations in previous clinical trials that tafenoquine may be associated with the development of corneal deposits and elevations in serum creatinine. In 120 healthy volunteers who received tafenoquine or placebo in a 2:1 randomization, there was no effect on night vision or other ophthalmic indices measured. Persons taking tafenoquine also showed no difference in mean change in glomerular filtration rate (GFR, mL/s/1.73 m(2)) after 6 months of dosing, with a treatment difference of -0.061 (95% confidence interval, -0.168, 0.045), and non-inferiority margin of -0.247 mL/s/1.73 m(2). Tafenoquine was well tolerated over the course of the study. The results of this study showed no clinically significant effects of tafenoquine on ophthalmic or renal function, and support its continued development as an antimalarial drug.
