Patterns of oncogene co-expression at single cell resolution in cancer influence survival
AbstractBackgroundCancers often overexpress multiple clinically relevant oncogenes. However, it is not known if multiple oncogenes within a cancer combine uniquely in specific cellular sub-populations to influence clinical outcome. We studied this phenomenon using the prognostically relevant oncogenes MYC, BCL2 and BCL6 in Diffuse Large B-Cell Lymphoma (DLBCL).MethodsQuantitative multispectral imaging simultaneously measured oncogene co-expression at single-cell resolution in reactive lymphoid tissue (n=12) and four independent cohorts (n=409) of DLBCL. Mathematically derived co-expression phenotypes were evaluated in DLBCLs with immunohistochemistry (n=316) and eight DLBCL cohorts with gen…
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…
