Intervention/exposure
Study type
Interventional(has expanded access)
Description of intervention(s) / exposure
Treatment: Other - Tisagenlecleucel
Treatment: Drugs - Lymphodepleting chemotherapy

Experimental: Tisagenlecleucel - Adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) who received tisagenlecleucel.


Treatment: Other: Tisagenlecleucel
The target dose of CTL019 transduced cells for adult patients consisted of a single infusion of 5 x 10\^8 viable CTL019 transduced cells, which was administered via intravenous infusion. The acceptable dose range was 1 - 5x10\^8 viable CTL019 transduced cells.

Treatment: Drugs: Lymphodepleting chemotherapy
Prior to CTL019 cell infusion, an additional lymphodepleting chemotherapy cycle was planned. The use of any additional bridging therapy prior to the recommended lymphodepleting chemotherapy was at the discretion of the investigator and dependent on the patient's disease burden. Lymphodepleting chemotherapy was started 14 to 5 days before CTL019 infusion (D1) to allow for at least 48 hours from last dose of lymphodepleting chemotherapy to CTL019 infusion. The lymphodepleting regimen was: Fludarabine (25 mg/m\^2 intravenously \[i.v.\] daily for 3 doses) and cyclophosphamide (250 mg/m\^2 i.v. daily for 3 doses starting with the first dose of fludarabine).
