Randomized Controlled Trial Multicenter Study
Treatment of patients with mildly symptomatic pulmonary arterial hypertension with bosentan (EARLY study): a double-blind, randomised controlled trial.
Treatments for pulmonary arterial hypertension have been mainly studied in patients with advanced disease (WHO functional class [FC] III and IV). This study was designed to assess the effect of the dual endothelin receptor antagonist bosentan in patients with WHO FC II pulmonary arterial hypertension. ⋯ Bosentan treatment could be beneficial for patients with WHO FC II pulmonary arterial hypertension.

Effect of aciclovir on HIV-1 acquisition in herpes simplex virus 2 seropositive women and men who have sex with men: a randomised, double-blind, placebo-controlled trial.
Across many observational studies, herpes simplex virus type 2 (HSV-2) infection is associated with two-fold to three-fold increased risk for HIV-1 infection. We investigated whether HSV-2 suppression with aciclovir would reduce the risk of HIV-1 acquisition. ⋯ Our results show that suppressive therapy with standard doses of aciclovir is not effective in reduction of HIV-1 acquisition in HSV-2 seropositive women and MSM. Novel strategies are needed to interrupt interactions between HSV-2 and HIV-1.

Effect of laquinimod on MRI-monitored disease activity in patients with relapsing-remitting multiple sclerosis: a multicentre, randomised, double-blind, placebo-controlled phase IIb study.
A 24-week phase II trial has shown that 0.3 mg of laquinimod given daily to patients with relapsing-remitting multiple sclerosis was well tolerated and reduced the formation of active lesions. We assessed the effect of oral daily 0.3 and 0.6 mg laquinimod on MRI-monitored disease activity in a 36-week double-blind, placebo-controlled phase IIb study. ⋯ In patients with relapsing-remitting multiple sclerosis, 0.6 mg per day laquinimod significantly reduced MRI-measured disease activity and was well tolerated.
