Leerink analyst Geoffrey Porges notes that Celgene has announced top-line results from Phase 1b study of GED-301 in Crohn's Disease, and says that absent statistical analyses or a greater insight into participant performance across the study's treatment arms, or longer duration of follow-up, it is difficult to evaluate the full significance of these results. Nonetheless, the analyst believes the drug seems to have some modest efficacy which bodes positively for potential approval as a front-line agent in Crohn's Disease. He reiterates a Market Perform rating on the shares.
