Tafasitamab

Tafasitamab is dosed at 12 mg/kg and given intravenously (IV) weekly for 3 weeks on Days 0,7,14).

Allogeneic NK cells are given intravenously (IV) weekly for 3 weeks on Days 0, 7, 14. Dose escalation will be conducted using a Bayesian optimal interval (BOIN) design starting at dose level 1 (500 x 106 cells) and proceeding to dose level 2 (1,000 x 106 cells) if criteria are met.

More than 80,000 cases of non-Hodgkin lymphoma (NHL) are diagnosed each year in the United States (US), with nearly 20,000 people dying from this group of diseases annually. There are several subgroups of NHL, with the B cell lymphomas being much more common than T-cell lymphomas.

This research study is for people who have relapsed or refractory B-cell non-Hodgkin's lymphoma (NHL) that has not responded to two or more lines of therapy. The purpose of this study is to identify the recommended dose of allogeneic NK cells in combination with IL-2, Tafasitamab and Rituximab for the treatment of relapsed or refractory B-cell non-Hodgkin's lymphoma.

NK cells are an investigational (experimental) treatment which means they are not approved by the Food and Drug Administration (FDA). NK cells are a type of lymphocyte that's part of the body's natural immune system, and they can kill cancer cells by creating pores in the cancer cell membranes and inducing apoptosis (programmed cell death).

• Age 18 years or older
• Diagnosis of B-cell NHL (indolent and aggressive subtypes) including diffuse large B-cell lymphoma not otherwise specified (DLBCL NOS), high grade B-cell lymphoma (HGBCL), primary mediastinal B-cell lymphoma (PMBCL), follicular lymphoma (FL), chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), marginal zone lymphoma (MZL), and mantle cell lymphoma (MCL)
• Participants must have measurable disease as defined by Lugano 2014 criteria for NHL or iwCLL 2018 criteria for CLL. For NHL, measurable disease is defined as ≥1 measurable lesion (nodal or extra nodal) ≥1.5 cm in longest diameter by CT or PET/CT. For CLL, iwCLL criteria includes: presence of lymphocytosis (e.g., ALC ≥5 × 10⁹/L), lymphadenopathy ≥1.5 cm, and/or disease-related cytopenias (anemia, thrombocytopenia).
• Relapsed and/or refractory after two or more lines of systemic therapy, including prior CD19 and/or CD20 directed therapies
• For participants who have received a prior CD19 or CD20 directed therapy, the presence of CD19 and/or CD20 expression (by flow cytometry and/or immunohistochemistry) must be demonstrated on a post-treatment relapse biopsy
• ECOG Performance Status \</= 2
