Brief summary

The goal of this clinical trial is to determine the outcome of patients with immune checkpoint inhibitor-mediated diarrhea/colitis (IMC) treated with faecal microbiota transplantation (FMT) in a randomised, placebo-controlled trial. The aim of the present study is to assess the feasibility, pilot efficacy, and safety of FMT for patients with IMC. Participants will be treated two times with capsule FMT or placebo capsules in a 1:1 ratio. The intervention treatment will be an add-on to the patients' standard treatment for IMC. Researchers will compare the FMT-treated group to the placebo-treated group to see if FMT promotes remission of IMC.

Design outcomes

Primary

MeasureTime frameDescription
Clinical remission of immune-mediated diarrheaAt 42 days after intervention treatmentNumber of patients with steroid-free resolution of diarrhea, defined as \< 3 liquid stools (Bristol \<6) per 24 hours during day 40 and 41 after the last intervention treatment.

Secondary

MeasureTime frameDescription
Remission of colitis defined by CTCAEAt 42 days after intervention treatmentNumber of patients in steroid-free clinical remission of colitis 6 weeks (42 days) after the last intervention treatment. Clinical remission is defined as asymptomatic in regards to colitis (CTCAE colitis grade 1 or less), at day 40 and 41.
Therapy response of FMTUp to 12 weeks after intervention treatmentTherapy response defined as a decrease of at least 3 points in Simple Clinical Colitis Activity Index (SCCAI) score, at weeks 1, 6 and 12 after the last intervention treatment.
Number of days until CTCAE diarrhea grade 1Up to 12 weeks after intervention treatmentNumber of days until less than 4 stools over baseline per day (CTCAE diarrhea grade 1 or less), lasting a minimum of 48 consecutive hours with no increase in steroid dose in the 12 weeks of follow-up.
Number of days until resolution of diarrheaUp to 12 weeks after intervention treatmentNumber of days until resolution of diarrhea, defined as 3 or fewer Bristol type 6-7 stools per day, lasting a minimum of 48 consecutive hours.
Incidence of fecal microbiota transplantation (FMT)-related adverse eventsAt 42 days after intervention treatmentNumber of adverse events (AE) during first 6 weeks after intervention treatment. AE's will be graded by CTCAE.
Incidence of fecal microbiota transplantation (FMT)-related serious adverse eventsAt 12 weeks after intervention treatmentNumber of serious adverse events (SAE) during 12 weeks follow-up after the final intervention treatment. SAE's will be graded by CTCAE.
Faecal microbiota compositionUp to 6 weeks after intervention treatmentChanges in faecal microbiome composition from baseline to week 6 after the last intervention.
Gut mucosa-associated microbiomeUp to 6 weeks after intervention treatmentChanges in mucosa-associated microbiome from baseline to week 6 after the last intervention.
Faecal-calprotectinUp to 6 weeks after intervention treatmentPercentual change in faecal-calprotectin from prior to intervention to week 6 after the last intervention.
Blood immunological parametersUp to 6 weeks after intervention treatmentChanges in blood immunological parameters (including circulating cytokines) from baseline and at week 6 after the last intervention.
Remission of diarrhea defined by CTCAEAt 42 days after intervention treatmentNumber of patients in steroid-free clinical remission of diarrhea 6 weeks (42 days) after the last intervention treatment. Clinical remission is defined as \< 4 stools over baseline per day (CTCAE diarrhea grade 1 or less), at day 40 and 41.
ColectomyUp to 12 weeks after intervention treatmentColectomy during 12 weeks of follow-up.
MortalityUp to 12 weeks after intervention treatmentMortality during the 12 weeks of follow-up.
Accumulated steroid doseUp to 12 weeks after intervention treatmentAccumulated steroid dose (total dose in mg) during 12 weeks following experimental treatment.
Resumption of immune checkpoint inhibitor therapyUp to 12 weeks after intervention treatmentNumber of patients resuming immune checkpoint inhibitor therapy during the 12 weeks of follow-up.
Response to immune checkpoint inhibitor therapyUp to 12 weeks after intervention treatmentResponse to immune checkpoint inhibitor therapy defined by Response Evaluation Criteria in Solid Tumours (RECIST 1.1 and iRECIST).
Patient and physician perceptions of FMT treatmentAt 42 days after intervention treatmentPatient and physician perceptions of FMT treatment and the usage for IMC assessed by a patient questionnaire at week 6 and a physician questionnaire.
Health-related quality of lifeAt 42 days after intervention treatmentChanges in health-related quality of life assessed by EQ-5D-5L at baseline and week 6.
Endoscopic responseUp to 6 weeks after intervention treatmentEndoscopic response, defined as decrease in Mayo endoscopic score ≥1 grade, at week 6 after the last intervention treatment.
Endoscopic remissionUp to 6 weeks after intervention treatmentEndoscopic remission, defined as Mayo endoscopic score 0, at week 6 after the last intervention treatment.
HospitalisationUp to 12 weeks after intervention treatmentHospitalisation defined as the total number of days hospitalised, during 12 weeks of follow-up.
