Brief summary:
This is a phase 1 trial designed to evaluate safety and tolerability of chemotherapy in combination with inotuzumab ozogamicin, an investigational product, in adults with CD22-positive non-Hodgkin's lymphoma. The trial will involve two arms. In one arm, subjects will receive chemotherapy regimen R-CVP (rituximab, cyclophosphamide, vincristine and prednisone). In the other arm, subjects will receive R-GDP (rituximab, gemcitabine, cisplatinum and dexamethasone). Subjects in both arms will also receive inotuzumab ozogamicin.

Detailed description:

Arms:
arm 1: Subjects in arm 1 will be enrolled in dose escalation cohorts that will initially evaluate an escalating dose of cyclophosphamide in combination with set doses of inotuzumab ozogamicin, vincristine, prednisone, and rituximab. arm 2: Subjects in arm 2 will be enrolled in dose escalation cohorts that will initially evaluate escalating doses of gemcitabine and/or cisplatinum in combination with set doses of inotuzumab ozogamicin, dexamethasone, and rituximab.
