Xencor to Present Initial Data from the Phase 1 Study of XmAb®13676 in B-Cell Malignancies at the American Society of Hematology Annual Meeting

November 6, 2019 GMT

MONROVIA, Calif.--(BUSINESS WIRE)--Nov 6, 2019--

Xencor, Inc. (NASDAQ: XNCR), a clinical-stage biopharmaceutical company developing engineered monoclonal antibodies for the treatment of cancer, autoimmune diseases, asthma and allergic diseases, today announced that initial data from its ongoing Phase 1 dose-escalation study of XmAb ® 13676, a CD20 x CD3 bispecific antibody, in patients with B-cell malignancies will be presented in a poster session during the 61 st American Society of Hematology (ASH) Annual Meeting in Orlando, Florida on Monday, December 9, 2019.

“Initial results from dose-escalation cohorts demonstrate encouraging clinical activity in heavily pretreated patients with several subtypes of non-Hodgkin lymphoma, as well as chronic lymphocytic leukemia. The most common treatment-related adverse event has been fever. Cytokine release syndrome, the second most common adverse event, has been generally manageable with premedication,” said Bassil Dahiyat, Ph.D., president and chief executive officer at Xencor.

Key Highlights from the Abstract

The abstract with accepted data from the study are available through the ASH website. Updated results will be shared at the ASH Annual Meeting.

Presentation Details

About XmAb ® 13676

XmAb ® 13676 is a tumor-targeted antibody that contains both a CD20 binding domain and a cytotoxic T-cell binding domain (CD3) in a Phase 1 clinical trial for the treatment of B-cell malignancies. An XmAb ® bispecific Fc domain serves as the scaffold for these two antigen binding domains and confers long circulating half-life, stability and ease of manufacture on XmAb13676. CD20 is highly expressed on B-cell tumors, including in chronic lymphocytic leukemia (CLL) and non-Hodgkin lymphoma (NHL). Engagement of CD3 by XmAb13676 activates T cells for highly potent and targeted killing of CD20-expressing tumor cells.
