Léčba venetoclaxem (26 cyklů) se 6 cykly nebo 12 cykly epcoritamabem u pacientů s relapsem nebo refrakterní CLL nebo SLL (AETHER)
Prospektivní randomizovaná studie fáze I/II léčby venetoclaxem (26 cyklů) se 6 cykly nebo 12 cykly epkoritamabu u pacientů s relapsující nebo refrakterní chronickou lymfocytární leukémií nebo malým lymfocytárním lymfomem
In this study, efficacy and safety of 2 regimens that combine the CD3-CD20 T cell engager epcoritamab with venetoclax will be tested in relapsed/refractory CLL and SLL patients. The trial starts with phase I part to establish the recommended dose level (RDL) of epcoritamab in the combination with venetoclax for the phase II trial.

Experimentální: Arm A
6 cycles epcoritamab + 26 cycles venetoclax |
Number of cycles of epcoritamab is either 6 (cycle 1-6) or 12 (cycle 1-12). Patients will be treated until they have received the total number of assigned treatment cycles or until progression, or severe toxicity, whichever comes first. All patients will receive venetoclax cycle 1-26 (a 5 week ramp-up of venetoclax will precede the first cycle). Patients will be treated until they have received the total number of assigned treatment cycles or until progression, or severe toxicity, whichever comes first. |
