Efficacy and safety of Lpc-37® in students facing examination stress: A randomized, triple-blind, placebo-controlled clinical trial (the ChillEx study).

Lpc-37 (Lpc-37) has previously shown to reduce perceived stress in healthy adults. The ChillEx study investigated whether Lpc-37 reduces stress in a model of chronic examination stress in healthy students. One hundred ninety university students (18-40 y) were randomized to take 1.

A randomized, double-blind, safety and tolerability study to assess the ophthalmic and renal effects of tafenoquine 200 mg weekly versus placebo for 6 months in healthy volunteers.

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.
