CLDXCelldex Therapeutics, Inc. (NASDAQ:CLDX) presented data on new product candidate CDX-1140, a fully human antibody targeted to CD40 that has demonstrated potent agonist and anti-lymphoma activity. Found on antigen presenting cells, such as dendritic cells, macrophages and B cells, CD40 is a key activator of the immune response and is expressed on many cancer cells, in particular B cell lymphomas. The data were presented at the American Society of Hematology (ASH) Annual Meeting on Saturday, December 3 in a poster titled “CDX-1140, A Novel Agonist CD40 Antibody with Potent Anti-lymphoma Activity” (Abstract #1848). CDX-1140 is expected to be ready to enter clinical studies in patients with advanced cancers, including lymphoma, in 2017.

“We have previously characterized CDX-1140 as possessing a needed balance between its agonist activity and its safety profile to allow for systemic dosing at levels that provide good tissue and tumor penetration, which we believe to be important in order to fully capture the benefit of CD40 immunotherapy,” said Tibor Keler, Ph.D., Executive Vice President and Chief Scientific Officer of Celldex Therapeutics. “With this study in preclinical lymphoma tumor models, we show both direct and indirect anti-lymphoma activity as well as synergistic anti-lymphoma activity with our CD27 agonist varlilumab, supporting potential combination treatment in this setting.”

The poster features detailed analyses of the anti-lymphoma efficacy of CDX-1140 both as a single-agent and in combination with varlilumab, Celldex’s agonist antibody that binds and activates CD27, or with human immune cells. It is available on the “Publications” page of the “Science” section of the Celldex website. Key findings include:

  • CDX-1140 elicits direct anti-tumor activity against CD40-positive lymphomas in preclinical tumor models.
  • The addition of human peripheral blood mononuclear cells (PBMCs) to the tumor models enhances the anti-tumor activity of CDX-1140 compared to the administration of either human PBMC or CDX-1140 alone, indicating an activated anti-tumor immune response by CDX-1140 in addition to direct anti-tumor activity.
  • The combination of CDX-1140 and varlilumab, elicited greater anti-tumor activity than either antibody alone.

Celldex is currently performing manufacturing and IND-enabling studies to support Phase 1 dose-escalation studies of CDX-1140. The Company believes that the potential for CDX-1140 will be best defined in combination studies with other immunotherapies or conventional cancer treatments.

Additionally, data from investigator sponsored research with varlilumab, CDX-301 and CDX-1401 were/will be presented by Celldex’s collaborating investigators during the ASH Annual Meeting.
