NT219 Combined With Standard of Care Biologic Therapy in Recurrent/Metastatic Head and Neck Squamous Cell Carcinoma

NT219 is a first-in-class small molecule targeting IRS 1/2 and STAT3. Preclinical studies in melanoma have shown NT219 induces PD-L1 expression in vitro and in vivo, resulting in increased efficacy of PD-1 inhibition via synergistic antitumor effect in PD-1 sensitive models and restoration of sensitivity in resistant models. NT219 also synergized with cetuximab in vitro and reversed cetuximab resistance in a head and neck cancer xenograft platform.
