Pharma: Clinic Roundup

• Janssen Research & Development LLC, of Spring House, Pa., a unit of Johnson & Johnson, said a Phase IIb study testing Stelara (ustekinumab) in moderate to severe Crohn's disease showed that, among patients who had previously failed or were intolerant to at least one tumor necrosis factor antagonist, a significantly greater proportion receiving intravenous Stelara achieved the primary endpoint of clinical response at week six, defined as a 100-point reduction in Crohn's Disease Activity Index, compared to patients receiving placebo (40 percent vs. 24 percent).
