Study Evaluating Chemotherapy in Combination With Inotuzumab Ozogamicin In Subjects With Non-Hodgkin's Lymphoma

AN OPEN-LABEL, PHASE 1 STUDY OF R-CVP OR R-GDP IN COMBINATION WITH INOTUZUMAB OZOGAMICIN IN SUBJECTS WITH CD22-POSTIVE NON-HODGKIN'S LYMPHOMA

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.

Inclusion Criteria:

• Dose escalation cohorts: subjects with diagnosis of CD22-positive Non-Hodgkin's Lymphoma (NHL) who have had at least 1 prior anticancer treatment, including prior treatment with rituximab and chemotherapy.
• Expanded maximum tolerated dose (MTD) confirmation and preliminary efficacy cohorts: subjects with diagnosis of CD22-positive NHL who have had at least 1 prior anticancer treatment, including prior treatment with rituximab and chemotherapy or newly diagnosed subjects who are not candidates for anthracycline-based therapy.
• At least 1 measurable disease lesion that is > 1 cm in the longest transverse diameter, with a product of the diameters > 2.25 cm2 by CT or magnetic resonance imaging (MRI).

Exclusion Criteria:

• Candidate for potentially curative therapy such as stem cell transplantation.
• Prior allogeneic hematopoietic stem cell transplantation (HSCT).
• Prior autologous transplantation, radioimmunotherapy, or other anti CD22 immunotherapy <= 6 months before the first dose of investigational product.
• More than 3 previous combination chemotherapy (2 or more cytotoxics) anticancer regimens.
