Celldex Presents Promising Data from CDX-0159 and CDX-527 Programs
-CDX-0159 IND accepted; Phase 1 study to start by YE 2019-
-CDX-527 on track for IND filing in 1H 2020-
“Our preclinical development efforts have yielded two very exciting candidates for continued advancement,” said
CDX-0159 Presentation Highlights:
CDX-0159 is a humanized monoclonal antibody that specifically binds the receptor tyrosine kinase KIT and potently inhibits its activity. KIT is expressed in a variety of cells, including mast cells, and its activation by its ligand SCF regulates mast cell functions including activation and survival. In certain inflammatory diseases, such as chronic idiopathic urticaria (CIU), mast cell activation plays a central role in the onset and progression of the disease.
In a Phase 1 clinical study with Celldex’s KIT antagonist monoclonal antibody, CDX-0158, robust inhibition of mast cell activity was observed supporting the concept that targeting KIT can modulate mast cell activity and potentially provide clinical benefit in mast cell related diseases. CDX-0158 was re-engineered and replaced with CDX-0159, a New Molecular Entity (NME), to ablate Fc receptor interactions and effector function and improve its safety profile, while preserving full KIT inhibitory activity. In addition, CDX-0159 was modified to provide extended half-life following administration.
Celldex’s Investigational New Drug (IND) Application for CDX-0159 has been accepted by the
CDX-527 Presentation Highlights:
Bispecific antibodies that engage two independent pathways involved in controlling immune responses to tumors are a rapidly growing area for the development of next generation PD-1 inhibitors. CDX-527 is the first candidate from Celldex’s bispecific platform and uses Celldex’s proprietary highly active anti-PD-L1 and CD27 human antibodies to couple CD27 co-stimulation with blockade of the PD-L1/PD-1 pathway. Celldex's prior clinical experience with combining CD27 activation and PD-1 blockade provide the rationale for linking these two pathways into one molecule. The data presented at
Celldex is developing targeted therapeutics to address devastating diseases for which available treatments are inadequate. Our pipeline includes immunotherapies and other targeted biologics derived from a broad set of complementary technologies which have the ability to engage the human immune system and/or directly inhibit tumors to treat specific types of cancer or other diseases.
