  • Relapsed (disease that has recurred following a response) or refractory (disease that failed to respond to prior therapy) disease following at least one multi-agent systemic treatment regimen [For China only: Adequate first line anti-DLBCL therapy is defined as having received at least 4 cycles of multiagent systemic treatment regimen containing rituximab and anthracycline, unless the participants are intolerant to the regimen, or had disease progression during the treatment. If disease progression occurred during the treatment period, then the disease is considered refractory where the number of treatment cycles will not be specified. For participants who are ineligible for anthracycline, anthracycline is not required.]
