Colitis

Brief summary

The goal of this clinical trial is to assess whether the early introduction of biological treatment with a TNF-alpha inhibitor (infliximab) in addition to corticosteroids for severe ir-colitis/diarrhoea will reduce the time to grade ≤ 1 ir-colitis/diarrhoea compared to corticosteroids alone in patients scheduled for ICI treatment for solid tumors and untreated mCTCAE grade 2-4 diarrhoea or colitis. The main question it aims to answer is: • Can an early introduction of biological treatment with a TNF-alpha inhibitor (infliximab) in addition to corticosteroids reduce the time to grade ≤ 1 ir-colitis/diarrhoea compared to corticosteroids alone. Participants will be randomised 1:1: Arm A: All patients will receive same dose of methylprednisolone i.v. daily. Arm B: Patients allocated to Arm B will in addition receive infliximab i.v. day 1 or 2. Study patients are evaluated with blood samples, faecal samples and by sigmoidoscopy. Procedures are performed before randomisation and as part of follow up.

Interventions

DRUGInfliximab

Infliximab is available in vials of 100 mg with pharmaceutical form of concentrate for solution for infusion. Participating sites will ensure availability of infliximab as part of the hospital's standard supply for use in the study.

DRUGMethylprednisolone

Methylprednisolone is available in vials of 40 mg. Methylprednisolone is a drug used for standard treatment first line for ir-colitis or diarrhoea CTCAE grade ≥ 3. Participating sites will ensure availability of methylprednisolone for use in the study as part of the hospitals standard supply.

DRUGPrednisolone

Prednisolone is available in tablets of 25 or 5 mg. Oral corticosteroids are internationally recommended as initial treatment for ir-colitis and ir-diarrhoea CTCAE grade 2 \[24-27\]. Participating sites will ensure availability of prednisolone for use in the study as part of the hospitals' standard supply.

Inclusion criteria

* Untreated mCTCAE grade 2-4 diarrhoea or colitis, or persistent mCTCAE grade 2 diarrhoea after administration of loperamide or equivalent for mCTCAE grade ≤ 2 diarrhoea * No signs of colonic perforation or infection * Age ≥ 18 * Understands the nature and purpose of the study and the study procedures and has signed informed consent * Is able to read, understand, and complete questionnaires and daily components of the patient Diary for the study period * Histologically confirmed malignant solid tumours * Treatment with immune checkpoint inhibitors (anti-CTLA-4, anti-PD-1 or anti-PD-L1) within the past 12 weeks. Immune checkpoint inhibitors can be administered as single agents or as combination therapy with anti-CTLA-4 and anti-PD-1 * No probability of a concomitant treatment (e.g. laxatives) other than the immune checkpoint inhibitor being the causal drug for the colitis or diarrhoea * Prior treatment with immune checkpoint inhibitors is allowed * Usage of prednisolone ≤ 10 mg daily for non irAE is allowed * Diagnostic work up including screening for viral hepatic infection and QuantiFERON-TB for mycobacterium tuberculosis must be requisitioned but will not need to be reported prior to study enrolment * Women of child bearing potential must have a negative serum (preferred) or urine pregnancy test within 72 hours prior to registration. * Note: women of childbearing potential are defined as premenopausal females capable of becoming pregnant (i.e. females who have had evidence of menses in the past 12 months, with the exception of those who had prior hysterectomy). However, women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, antiestrogens, low body weight, ovarian suppression or other reasons. * Patients of childbearing / reproductive potential should use adequate birth control measures, as defined by the investigator, during the study treatment period and after the study treatment: * for at least 6 months after the last study treatment, or depending on the duration antineoplastic treatment * Note: A highly effective method of birth control is defined as a method which results in a low failure rate (i.e. less than 1% per year) when used consistently and correctly. Such methods include: * Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal) * Progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable) * Intrauterine device (IUD) * Intrauterine hormone-releasing system (IUS) * Bilateral tubal occlusion * Vasectomized partner * Sexual abstinence

Exclusion criteria

* Prior history of inflammatory bowel disease, colitis, or diarrhoea requiring treatment with any corticosteroid, or any other immunosuppressant medication * Prior history of recurrent bowel disease including symptomatic diverticulosis * Current positive testing for Clostridium difficile or other colonic infection * Current bacterial infection requiring antibiotic treatment, or systemic fungal infection * Ongoing antibiotic treatment for any reason * Treatment with systemic corticosteroids within the last four weeks prior to study enrolment (daily usage of prednisolone ≤ 10 mg for non irAE conditions is accepted) * Concurrent immune-related adverse events requiring immunosuppressant medication of any kind * Known hypersensitivity or contraindications to systemic corticosteroids or infliximab * Prior history of viral hepatitis with a positive viral load, known untreated mycobacterium tuberculosis, or known active herpes zoster infection

Secondary

MeasureTime frameDescription
Proportion of study subjects requiring rescue immunosuppressive medicationTime frame: seven daysArm A (initial corticosteroid only): infliximab if no improvement to grade ≤ 2 ir-colitis/diarrhoea after 3 days (time frame: seven weeks); Arm B (initial infliximab): second dose infliximab according to physicians decision if no improvement to grade ≤ 2 ir-colitis/diarrhoea after seven days
QoL by means of EORTC-QLQ-C30Change in score from baseline to 3, 12, 24, and 52 weeks after randomisationA 30-item questionaire developed to assess the quality of life of cancer patients. Item 1-28 is scaled in a 4 scale score from 'not at all' to 'very much'. Item 29-30 is a numeric rating scale from 1 to 7 assessing overall health/quality of life. One denotes very poor and 7 denotes excellent. Measure: changes in quality of life
QoL by means of selected PRO-CTCAE itemsChange in score from baseline to 3, 12, 24, and 52 weeks after randomisationA 8 item questionnaire assessing bowel related issues. The scales ranges from eg: Yes/No Never/rarely/occasionally/frequently/almost constant None/mild/moderate/severe/very severe Not at all/a little bit/ somewhat/quit a bit/very much Measure: changes in bowel related symptoms
