Kineta is a clinical-stage biotechnology company with a mission to develop next generation immunotherapies that transform patients’ lives.  Kineta has leveraged its expertise in innate immunity with an intent to develop first or best-in-class immunotherapies that address the major challenges with current cancer therapy.  For more information on Kineta, please visit www.kinetabio.com, and follow Kineta on Twitter, LinkedIn and Facebook.

PiiONEER™ Platform is focused on developing fully human monoclonal antibodies that target novel innate immune pathways.  It was designed for the discovery and development of first or best-in-class immunotherapies that address the major challenges with cancer immune resistance to current therapies. Utilization of the PiiONEER™ Platform results in novel, well-characterized lead antibody therapeutics that can be efficiently advanced into formal IND-enabling and clinical studies.

KVA12123 (formerly referred to as KVA12.1)  is a potentially differentiated VISTA blocking immunotherapy to address the problem of immunosuppression in the tumor microenvironment.  It is a fully human engineered IgG1 monoclonal antibody that was designed to bind to VISTA through a unique epitope. KVA12123 may be an effective immunotherapy for many types of cancer including NSCLC (lung), colorectal, renal cell carcinoma, head and neck, and ovarian.  These initial target indications represent a significant unmet medical need with a large worldwide commercial opportunity for KVA12123.

Anti-CD27 mAb program:  Kineta has developed a diverse set of anti-CD27 agonist antibodies. They are fully human monoclonal antibodies (mAbs) that demonstrate low nanomolar (nM) binding affinity to CD27 in humans. In preclinical studies, Kineta’s selected lead anti-CD27 agonist mAbs induce T cell proliferation and secretion of cytokines involved in T cell priming and recruitment, demonstrating the ability to potentiate new anti-tumor responses.
