Clinical Data In addition to achieving the primary endpoint, statistical significance was also met for the secondary endpoint of the whole body itch numeric rating scale (NRS) [defined as at least a 4-point reduction from baseline] at week 16 with OTEZLA versus placebo.The safety profile was generally consistent with the known safety profile of OTEZLA, and no new safety signals were identified in the trial. Treatment-emergent adverse events that occurred in at least 5 percent of patients in either treatment group were diarrhea (30.5 percent for OTEZLA and 10.8 percent for placebo), nausea (21.5 percent and 5.9 percent, respectively), headache (11.5 percent and 4.9 percent) and vomiting (5.5 percent and 2.0 percent).
