“We look forward to continuing our manufacturing partnership with Samsung Biologics for our lead product candidate, cosibelimab, currently in a pivotal clinical trial for metastatic cutaneous squamous cell carcinoma. Checkpoint is on track to report full topline results from the pivotal trial in mid-2021,” said James F. Oliviero, President and Chief Executive Officer of Checkpoint. “This agreement provides Checkpoint access to a top-tier manufacturing site for the long-term commercial supply of cosibelimab after potential regulatory approvals worldwide.”
“We are extremely proud of this extended partnership with Checkpoint to support our client and make an impact by helping broader patient populations in need,” said Dr. Tae Han Kim, CEO of Samsung Biologics. “As a reliable contract development and manufacturing organization (“CDMO”) service provider, Samsung Biologics offers the highest quality manufacturing for Checkpoint to assist in its endeavor to bring innovative treatments for patients all around the globe.”
Samsung Biologics recently announced it will break ground on its fourth plant within this year to commence manufacturing activities in the latter half of 2022, deliver world-class client satisfaction, and fulfill the needs of the growing biopharmaceutical market.
About Cutaneous Squamous Cell Carcinoma
Cutaneous squamous cell carcinoma (“CSCC”) is the second most common human cancer in the United States, with an estimated annual incidence of 700,000 cases. While most cases are localized tumors amenable to curative resection, approximately 8% of patients will experience a local recurrence, 5% of patients will develop nodal metastases, and an estimated 2% of patients will die from their disease. Ten-year survival rates are less than 20% for patients with regional lymph-node involvement. For those patients who develop distant metastases, the median survival time is estimated to be less than two years. In addition to being a life-threatening disease, CSCC causes significant functional morbidities and cosmetic deformities based on tumors commonly arising in the head and neck region and invading blood vessels, nerves and vital organs such as the eye or ear.
Cosibelimab (formerly referred to as CK-301) is a potential best-in-class, 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. 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 through sustained >99% target tumor occupancy to reactivate an antitumor immune response 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.
About Checkpoint Therapeutics
Checkpoint Therapeutics, Inc. (“Checkpoint”) is a clinical-stage immunotherapy and targeted oncology company focused on the acquisition, development and commercialization of novel treatments for patients with solid tumor cancers. Checkpoint is evaluating its lead antibody product candidate, cosibelimab, a potential best-in-class anti-PD-L1 antibody licensed from the Dana-Farber Cancer Institute, in an ongoing global, open-label, multicohort Phase 1 clinical trial in checkpoint therapy-naïve patients with selected recurrent or metastatic cancers, including ongoing cohorts in locally advanced and metastatic cutaneous squamous cell carcinoma intended to support one or more applications for marketing approval. In addition, Checkpoint is evaluating its lead small-molecule, targeted anti-cancer agent, CK-101, a third-generation epidermal growth factor receptor (“EGFR”) inhibitor, as a potential new treatment for patients with EGFR mutation-positive non-small cell lung cancer.
