Epcoritamab + Ibrutinib

Undergo bone marrow aspiration and biopsy

PRIMARY OBJECTIVES: I. Determine the recommended phase II dose (RP2D) and safety of epcoritamab plus ibrutinib. II. Determine the rate and severity of cytokine release syndrome (CRS). SECONDARY OBJECTIVES: I. Determine the complete response (CR) rate (Lugano 2014) after cycle 12 or the last dose of treatment if stopped earlier. II.

Determine the overall response rate (ORR) (CR + partial response [PR]) (Lugano 2014), progression-free survival (PFS), duration of response (DOR), and overall survival (OS) of patients treated at the RP2D. III. Determine the best ORR and CR rate (Lugano 2014). EXPLORATORY OBJECTIVES: I. Characterize cytokine profile following ibrutinib and epcoritamab and explore whether levels of cytokine production correlate with both the appearance of CRS and ORR. II.

This phase Ib/II trial evaluates the safety, optimal dose, and efficacy of the combination of epcoritamab and ibrutinib in treating patients with aggressive B-cell non-Hodgkin lymphoma that has come back (relapsed) or responded to previous treatment (refractory). Epcoritamab, a bispecific antibody, binds to two different types of receptors (proteins present on the cell surface) at the same time. The two receptors that epcoritamab binds to are called CD3 and CD20.

CD3 is found on T cells, which are important cells of the immune system that help fight cancer and infections. CD20 is found on the surface of most types of aggressive B-cell non-Hodgkin lymphoma cells. By binding to both CD3 and CD20, epcoritamab brings the two cells close together so the T cells can fight and kill the lymphoma B cells.
