Celldex Therapeutics, Inc., a biopharmaceutical company, focuses on the development, manufacture, and commercialization of novel therapeutics for human health care primarily in the United States. The company has a pipeline of drug candidates in development for the treatment of cancer and other difficult-to-treat diseases based on its antibody focused precision targeted immunotherapy platform. Its lead drug candidates include rindopepimut (CDX-110), a targeted immunotherapeutic in a pivotal Phase III study for the treatment of front-line glioblastoma and a Phase II study for the treatment of recurrent glioblastoma; and CDX-011, an antibody-drug conjugate, which completed a randomized Phase IIb study for the treatment of advanced breast cancer. The company also has various earlier stage candidates in clinical development, such as CDX-1135, a molecule that inhibits a part of the immune system called the complement system; CDX-1127, a therapeutic fully human monoclonal antibody for cancer indications that is in Phase I study in patients with selected malignant solid tumors or hematologic cancers; CDX-301, an immune cell mobilizing agent and dendritic cell growth factor, which completed Phase I study in healthy subjects; and CDX-1401, an antibody-targeted technology program for cancer indications that completed Phase I study in combination with toll-like receptor agonists poly-ICLC. Its preclinical product candidate includes CDX-014, a human monoclonal antibody-drug conjugate that targets TIM-1, a molecule that is expressed on renal and ovarian cancers with minimal expression in normal tissues. It has research collaboration and license agreements with Medarex, Inc.; Rockefeller University; Duke University Brain Tumor Cancer Center; Ludwig Institute for Cancer Research; Thomas Jefferson University; University of Southampton; Amgen Inc.; Amgen Fremont; and Seattle Genetics, Inc.
