A phase III study examining the use of the phosphodiesterase type-5 inhibitor tadalafil in men with BPH is planned for 2006. The scheduled trial follows results of a double-blind, placebo-controlled phase II study showing clinically meaningful and statistically significant improvement in lower urinary tract symptoms in men with BPH who were treated for 6 weeks with once-daily tadalafil, 5 mg, according to Lilly ICOS LLC.
