主要终点
Proportion of patients in both treatment arms in steroid-free clinical remission (PRO-2 remission: average AP≤1 and average SF≤3 without any steroid use in the previous 28 days) at both week 56 and week 112 of the study (sustained steroid-free clinical remission).

研究概览

简要总结

To assess the long-term clinical efficacy of a ustekinumab 90mg SC Q4w regimen in patients with CD previously enrolled in the REScUE study because of secondary loss of response to a ustekinumab 90mg SC Q8w regimen.

入排标准

年龄范围
18 years 至 65+ years(65+ Years, 18-64 Years)
接受健康志愿者

入选标准

  • Previous inclusion in the REScUE study and having reached the end of this study at week
  • Adequate contraception in females of reproductive age (oral, transdermal, injectable contraception, intra-uterine device, sterilisation or barrier method). Adequate contraception in males (sterilization or barrier method) if his female partner is of reproductive age.
  • Have the capacity to understand and sign an informed consent form.
  • Be able to adhere to the study visit schedule and other protocol requirements.

排除标准

  • Patients previously enrolled to the ustekinumab 90 mg SC Q4w-arm during REScUE who were on concomitant steroid use >20 mg prednisone equivalents (budesonide >6 mg; beclomethasone dipropionaat >5 mg) at any time point in the last 28 days before the end of REScUE at week
  • Patients previously enrolled to the ustekinumab 90 mg SC Q4w-arm during REScUE that did not reach the following criteria at the end of REScUE at week 48: Clinical remission (defined as average AP≤1 and average SF≤3) OR clinical response (defined as a drop of at least 50% in average AP and/or a drop of at least 50% in average SF as compared to REScUE baseline, and both average AP and SF no worse than REScUE baseline) AND Endoscopic remission (defined as a total SES-CD <5 or for isolated ileitis SES-CD <4) OR endoscopic response (defined as a drop of at least 50% in total SES-CD score as compared to REScUE baseline)
  • Patients who developed an anaphylactic or severe allergic reaction to study medication during REScUE.
  • Patients with any of the following laboratory tests at W0 of REScUE-OLE : Hemoglobin level <8.5 g/dL, Platelets level <100.000 /mm3, Serum creatinine level ≥1.7 mg/dL, AST and ALT level >3 times the upper limit of normal range, Direct (conjugated) bilirubin level ≥3.0 mg/dL
  • Patients with an ongoing treatment with another concomitant biological (vedolizumab, anti-TNF), a JAK-inhibitor or any investigational product for the treatment of CD at the end of REScUE at week
  • Patients who experience or have an ongoing infection event confirmed by positive stool or blood testing (including gastrointestinal pathogens, tuberculosis, HIV, hepatitis B, hepatitis C) should not initiate REScUE-OLE until (i) this event has completely resolved as shown by the termination of treatment with anti-infective medication, or (ii) this event is considered to be in stable remission under anti-infective medication in case of HIV, hepatitis B and hepatitis C.
  • Patients with an impassable stenosis even after attempt of endoscopic balloon dilatation.
  • Patients with an intra-abdominal abscess, or patients with an intra-anal abscess without adequate drainage by e.g. a seton placement.
