A Study to Check How Often People Treated With Darvadstrocel for Crohn's Disease Are Diagnosed With Cancer

Exclusion criteria

• . Has less than 12 months of uninterrupted data within country-specific data source prior to index date.
• . Has not meet quality indicators for country-specific data source (if applicable).
• . Has diagnosis of cancer prior different from non-melanoma skin cancer to index date. This will minimise the misclassification of prevalent or metastatic cancer as incident cases for the analysis of the study objectives.
• . Has diagnosis of ulcerative colitis at any point during the study period and medical history period. This will avoid potential ascertainment bias as there is currently no gold standard for differential diagnosis in IBD. Approximately 5 percent (%) to 15% of cases do not meet strict criteria for either ulcerative colitis (UC) or CD and in up to 14% of participants classified as UC and CD, the diagnosis changes over time.
• . Has record of proctectomy or colectomy prior to index date. Proctectomy and colectomy are considered "last chance" surgery options for anal fistulas or other complications of CD. These participants are not the target population for darvadstrocel. They would not be eligible for darvadstrocel administration and loss of their gastrointestinal tract would affect the risk of colorectal cancer; the most common cancer associated with CD.
