Phase II Study of HMPL-004 in Subjects With Crohn's Disease

Percentage of subjects with CDAI clinical response -100 at Week 8 based on ITT population using the WOCF method to impute missing CDAI scores at Week 8. Clinical response -100 was defined as CDAI score decrease of ≥100 points from baseline in subjects who had no change in concomitant medications for Crohn's disease except for steroids, which could be tapered after Week 8. The CDAI consists of eight variables, including Liquid or very soft stools, Abdominal pain, General well-being, Features of extra-intestinal disease, Oplates for diarrhea, Abdominal mass, Hematocrit and Body weight below standard, each weighted according to its ability to be predictive of disease activity. The total score ranges from 0 to over 600 with higher scores indicating higher disease activity or worse outcome.
