Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| difference in microbiome biomarkers between patients developing colitis after exposure to targeted therapy and those not developing colitis | At the end of the study, after 2 years. | With the different species and metabolites between the 2 groups of patients (patients developing diarrhea after exposure to Ibrutinib and those not developing diarrhea), we will create a risk score for occurrence of diarrhea during treatment with Ibrutinib, on the previously developed model (Montassier et al, 2016, Genome medicine) |
Secondary
| Measure | Time frame |
|---|---|
| Identify biomarkers of the gut microbiota associated with the occurrence of severe diarrhea (grade 3 and 4 CTCAE, version 4.0) in patients treated with Ibrutinib for malignant hemopathy B. | At the end of the study, after 2 years. |
| Identify biomarkers of gut microbiota associated with the occurrence of diarrhea by subgroup: patients treated with Ibrutinib alone, patients treated with Ibrutinib in combination with another molecule | At the end of the study, after 2 years. |
| Creation of a predictive score of the occurrence of diarrhea in patients treated with Ibrutinib for malignant hemopathy B, including the biomarkers of the intestinal microbiome and the clinical characteristics of the patient | At the end of the study, after 2 years. |
