简要总结
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.

入选标准
- •Age 18 to 80, nonhospitalized, male or nonpregnant, nonlactating females voluntarily able to give informed consent.
- •Crohn's disease of at least 6 months' duration.
- •Endoscopic and/or histopathological and/or radiological documentation consistent with Crohn's disease obtained preferably within 24 months of screening.
- •Crohn's disease involving the colon and/or the ileum.
- •CDAI score from 220 to 400 (inclusive) at the time of the Screening visit. The CDAI must have remained between 220 and 400 after the 1-week Screening period for the patient to be eligible.
- •Patients may have been receiving oral or topical 5-ASA compounds provided the dosage had been stable for at least the 14-day period before the Screening visit. Patients were to be maintained on the 5-ASA compound at a constant dose at least through Day 57.
排除标准
- •Patients with evidence of current GI infection (bacterial or parasitic) or significant infection within 45 days of the screening visit.
- •Patients with a serious underlying disease other than Crohn's disease including presence or history of malignancy (except basal cell carcinoma) and histological evidence of dysplasia.
- •Patients with significantly impaired liver or renal function. This includes those with established chronic liver disease including hepatitis B or C.
- •Patients with the laboratory abnormalities
- •Patients using ethanol or consuming illicit drugs which, in the investigator's opinion, may interfere with compliance with the study procedures.
- •Patients with active psychiatric problems which, in the investigator's opinion, may interfere with compliance with the study procedures.
- •Patients who have previously received or who are currently receiving treatment with a monoclonal antibody.
- •Patients receiving any investigational therapy, excluded medications as defined in protocol, or any approved therapy in an investigational protocol within 30 days prior to screening.
- •Patients unable to attend all the study visits or comply with study procedures.
