Title: Phase 2 Randomized, Placebo-Controlled, Double-Blind, Parallel Group Study to Determine the Safety, Pharmacokinetics, and Effectiveness of LDP-02 in Patients With Mildly to Moderately Active Crohn's Disease
Brief Summary: The objectives of this study were to assess the safety and tolerability of LDP-02 in patients with active Crohn's disease who were not receiving corticosteroids or immunosuppressives, to assess the ability of LDP-02 to reduce Crohn's disease activity, and to obtain pharmacokinetic (PK) and pharmacodynamic(PD)information for LDP-02 in patients with active Crohn's disease.
