Randomized Controlled Trial Multicenter Study
Nonmetastatic, Castration-Resistant Prostate Cancer and Survival with Darolutamide.
Darolutamide is a structurally distinct androgen-receptor inhibitor that is approved for the treatment of nonmetastatic, castration-resistant prostate cancer. In the planned primary analysis of a phase 3 trial, the median metastasis-free survival was significantly longer with darolutamide (40.4 months) than with placebo (18.4 months). The data for the analysis of overall survival were immature at the time of the primary analysis. ⋯ Among men with nonmetastatic, castration-resistant prostate cancer, the percentage of patients who were alive at 3 years was significantly higher among those who received darolutamide than among those who received placebo. The incidence of adverse events was similar in the two groups. (Funded by Bayer HealthCare and Orion Pharma; ARAMIS ClinicalTrials.gov number, NCT02200614.).

Randomized Controlled Trial Multicenter Study Comparative Study
Eflornithine plus Sulindac for Prevention of Progression in Familial Adenomatous Polyposis.
The efficacy and safety of combination therapy with eflornithine and sulindac, as compared with either drug alone, in delaying disease progression in patients with familial adenomatous polyposis are unknown. ⋯ In this trial involving patients with familial adenomatous polyposis, the incidence of disease progression was not significantly lower with the combination of eflornithine and sulindac than with either drug alone.

Factor VIII replacement products have improved the care of patients with hemophilia A, but the short half-life of these products affects the patients' quality of life. The half-life of recombinant factor VIII ranges from 15 to 19 hours because of the von Willebrand factor chaperone effect. BIVV001 (rFVIIIFc-VWF-XTEN) is a novel fusion protein designed to overcome this half-life ceiling and maintain high sustained factor VIII activity levels. Data are lacking on the safety and pharmacokinetics of single-dose BIVV001. ⋯ In a small, early-phase study involving men with severe hemophilia A, a single intravenous injection of BIVV001 resulted in high sustained factor VIII activity levels, with a half-life that was up to four times the half-life associated with recombinant factor VIII, an increase that could signal a new class of factor VIII replacement therapy with a weekly treatment interval. No safety concerns were reported during the 28-day period after administration. (Funded by Sanofi and Sobi; ClinicalTrials.gov number, NCT03205163.).
