Durability of complete response after blinatumomab therapy for relapsed/refractory diffuse large B-cell lymphoma
Despite advances in standards of care, the prognosis of relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) remains poor. In these patients, 50–74% fail to respond to next line therapy,...
Glofitamab (Glofit) in Combination with Polatuzumab Vedotin (Pola): Phase Ib/II Preliminary Data Support Manageable Safety and Encouraging Efficacy in Relapsed/Refractory (R/R) Diffuse Large B-Cell Lymphoma (DLBCL)
Abstract Background: Glofit is a novel, CD20xCD3 T-cell-engaging bispecific antibody that provides monovalent binding to CD3 on T cells and bivalent binding to CD20 on B cells. As monotherapy, Glofit has shown promising response rates with manageable safety in R/R B-cell non-Hodgkin lymphoma (B-NHL) patients (pts; [Carlo-Stella et al. EHA 2021]). Because of their distinct and complementary mechanism of action, there is a rationale for combining Glofit with the anti-CD79b-targeted antibody-drug conjugate, Pola. NP39488 (NCT03533283) is a Phase Ib/II, open-label, multicenter, dose-escalation (DE) and expansion study evaluating Glofit + Pola or atezolizumab in R/R B-NHL pts (Hutchings et al. A…
Durability of complete response after blinatumomab therapy for refractory/relapsed aggressive B-cell non-Hodgkin lymphoma.
e19041 Background: Achieving durable response in patients (pts) with relapsed/refractory (R/R) aggressive B-cell lymphoma (B-NHL) is challenging. Blinatumomab, a bispecific T-cell engager (BiTE) immunotherapy targeting CD19-expressing cancer cells, has shown promising efficacy in pts with R/R aggressive B-NHL. We report the durability of complete response (DOCR) in pts treated with blinatumomab. Methods: The DOCR in pts with R/R aggressive B-NHL responding to blinatumomab was assessed using data from two phase 2 studies (study 1 [N = 25], NCT01741792; study 2 [N = 41], NCT02910063) in pts with R/R aggressive B-NHL. CR was assessed using Cheson (study 1) and Lugano (study 2) criteria. Time-…
