Comparison of Ustekinumab, Infliximab and Combination Therapy in Moderately to Severely Active Ulcerative Colitis

Recruiting now · Phase 2

Conditions studied: Ulcerative Colitis, Inflammatory Bowel Diseases

In brief

The goal of this clinical trial is to learn if combined therapy with infliximab and ustekinumab works better than using these drugs alone in adult patients with ulcerative colitis. It will also learn about the safety of this combination. The main questions it aims to answer are: Does the combination therapy improve the symptoms and heal the intestine quicker and better than these drugs administered alone? Does the combination therapy improve the quality of life better than these drugs administered alone? What medical problems do participants have when taking the combination therapy? Participants: Patients diagnosed with UC will be qualified to biologic therapy (infliximab/ustekinumab/infliximab + ustekinumab). Visit the clinic in stated periods for assessment and to apply medication. Take drugs based on the schedule.

Who can join

Age: 18 and older, up to 64. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Obtaining informed, written consent for the patient's participation in the in the study and for all planned procedures.
• Age ≥ 18 years and ≤65 at the time of screening.
• In the case of women of reproductive potential, agreement to not donate oocytes for the entire period of participation in the in the study and 6 months after receiving the last dose of the drug.
• For women of reproductive potential, agreement to use effective contraception (Table 4) during the entire period, during which the patient participates in the study and for a period counted from the last dose of 15 weeks if using UST (patients in arms B and C) or 6 months if using IFX (patients in arm A).
• Negative serum or urine pregnancy test in women of childbearing age.
• Diagnosis of UC a minimum of. 3 months prior to screening documented by:
• (a) medical source documentation of the patient with the result of an endoscopic examination that diagnosed features typical of UC.
• (b) a histopathological examination result consistent with UC. In the absence of a histopathological result, it is possible to take sections during the endoscopic examination for histopathological evaluation at the time of eligibility for the study with subsequent sending of the material to the local pathomorphology laboratory to confirm the diagnosis of UC before randomization.
• UC with moderate or severe activity defined as a Mayo scale score (Appendix 2) of 7 to 12 including the following sub-item values (each sub-item 0-3 points depending on the severity of the lesions):
• Frequency of bowel movements
• Bowel bleeding
• Endoscopic image of the colonic mucosa
• General medical evaluation and:
• with inadequate response to standard treatment, including corticosteroids and 6-mercaptopurine or azathioprine, or.
• intolerant of treatment with corticosteroids and 6-mercaptopurine or azathioprine, or
• having contraindications to treatment with corticosteroids and 6-mercaptopurine or azathioprine, or
• with loss of response to standard treatment, including to treatment with corticosteroids and 6-mercaptopurine or azathioprine, including patients:
• Steroid-resistant - in whom there is no clinical improvement despite the use of a daily steroid up to 0.75 mg/kg prednisolone for 4 weeks;
• Steroid-dependent - in whom failure to reduce the steroid dose below 10 mg/day, converted to prednisolone, within 3 months of starting steroid therapy or relapse of complaints within 3 months of steroid withdrawal.
• Refractory patients/about inadequate response to immunosuppressive treatment, defined as lack of remission or recurrence of complaints despite immunosuppressive treatment for at least 3 months at appropriate doses (azathioprine 2-2.5 mg/kg/day or 6-mercaptopurine 1-1.5 mg/kg/day).
• Patients taking 5-ASA derivatives, corticosteroids, immunosuppressants may be included in the study if they are taking a fixed and specified dose of the above drugs 14 days before the day of randomization.
