Frequently asked questions about CDX-585

What is CDX-585 used for?

CDX-585 is an investigational small molecule being studied in adults with advanced solid tumors, including non-small cell lung cancer. It was evaluated in a Phase 1 study that also enrolled patients with gastric, head and neck, ovarian, bladder, colorectal, esophageal, renal, pancreatic, and other advanced malignancies.

What does CDX-585 target?

CDX-585 targets ILT4 and PD-1, two immune checkpoint proteins. By binding both targets, the small molecule is designed to act on pathways that regulate immune cell activity in the tumor microenvironment. Both ILT4 and PD-1 belong to the immune checkpoint class of therapeutic targets.

Who is developing CDX-585?

CDX-585 is being developed by Celldex Therapeutics, Inc., which trades on the Nasdaq under the ticker CLDX. The company sponsored the Phase 1 study of the compound in patients with advanced malignancies.

What phase is CDX-585 in?

CDX-585 has been in Phase 1 clinical development. Its single registered trial, a Phase 1 study in advanced malignancies, is listed as completed. The drug is investigational and has not been approved by the FDA for any indication.

What clinical trials is CDX-585 in?

CDX-585 was studied in one registered clinical trial, NCT05788484, titled A Study of CDX-585 in Patients With Advanced Malignancies. The Phase 1 trial enrolled 20 participants in the United States and is listed as completed. It was an uncontrolled study without randomization or blinding.
