Checkpoint Therapeutics Announces Data Presentation at the European Society for Medical Oncology (ESMO) Congress 2019
NEW YORK, Sept. 16, 2019 (GLOBE NEWSWIRE) -- Checkpoint Therapeutics, Inc. (“Checkpoint”) (NASDAQ: CKPT), a clinical-stage immuno-oncology biopharmaceutical company focused on the acquisition, development and commercialization of novel treatments for patients with solid tumor cancers, today announced that new clinical data on cosibelimab (formerly CK-301), a potentially differentiated high affinity anti-PD-L1 antibody with functional Fc domain, will be presented at the upcoming European Society for Medical Oncology (ESMO) Congress 2019, taking place September 27 - October 1, 2019, in Barcelona, Spain. The poster presentation will provide updated interim results from Checkpoint’s ongoing multicenter Phase 1 clinical trial, including safety and efficacy data on additional patients and longer follow-up periods from the expansion cohorts. Checkpoint continues to enroll patients into potential registration-enabling cohorts in order to support one or more marketing application submissions based on this ongoing clinical trial.
“We are excited that our interim clinical data on cosibelimab has been selected for presentation at the ESMO Congress this year. With additional patients and longer follow-up, we believe the safety and efficacy data continue to build a compelling case that cosibelimab can be a significant player in a class of PD-(L)1 inhibitors that have grown into a $20 billion annual market,” said James F. Oliviero, President and Chief Executive Officer of Checkpoint Therapeutics. “We look forward to sharing our data with the world-renowned oncologists and researchers attending ESMO and the broader oncology community around the world.”
Details of the poster presentation are below:

About Cosibelimab
Cosibelimab (formerly referred to as CK-301) is a high affinity, fully-human monoclonal antibody of IgG1 subtype that directly binds to Programmed Death Ligand-1 (PD-L1) and blocks the PD-L1 interaction with the Programmed Death Receptor-1 (PD-1) and B7.1 receptors. PD-L1 is an immune-inhibitory checkpoint molecule expressed on epithelial and vascular endothelial cells, as well as by a number of immune cells, and is utilized by tumor cells as an immune escape mechanism. Cosibelimab’s primary mechanism of action is based on the inhibition of the interaction between PD-L1 and its receptors PD-1 and B7.1, which removes the suppressive effects of PD-L1 on anti-tumor CD8+ T-cells to restore the cytotoxic T cell response. Cosibelimab is potentially differentiated from the currently marketed PD-1 and PD-L1 antibodies with a half-life that supports sustained >99% target tumor occupancy and the additional benefit of a functional Fc domain capable of inducing antibody-dependent cell-mediated cytotoxicity (“ADCC”) for potential enhanced efficacy in certain tumor types.
