Key secondary endpoints demonstrated improvement in total IPSS starting at the first scheduled observation at week 4 (Cialis -4.0, placebo -2.3: p<.001) and the score remained decreased through 26 weeks (Cialis -5.5, placebo -4.5; p=.022). However, the magnitude of the treatment difference between placebo/finasteride and Cialis/finasteride decreased from 1.7 points at Week 4 to 1.0 point at Week 26, as shown in Table 20 and in Figure 7. The incremental benefit of Cialis beyond 26 weeks is unknown.2.Log in or register quickly and confidentially.
