About AST-008

AST-008 is an SNA consisting of toll-like receptor 9 agonists designed for immuno-oncology applications. As of January 31, 2020, we have dosed 17 patients in the Phase 1b stage of the clinical trial. We have observed no treatment related serious adverse events, nor have we observed any dose-limiting toxicity among the treated subjects. The most common reported adverse event was injection site reactions. In December 2019, we received preliminary results from the Phase 1b/2 stage of the clinical trial showing potential signs of anti-tumor activity in patients with Merkel cell carcinoma. In the second quarter of 2020, we plan to initiate a Phase 2 dose expansion for intratumoral AST-008 in combination with approved checkpoint inhibitors to treat two cohorts of patients with advanced or metastatic Merkel cell carcinoma or cutaneous squamous cell carcinoma. Each cohort is expected to enroll up to 29 patients who have failed anti-PD-1/PD-L1, or programmed cell death protein 1/programmed death-ligand 1, therapy. We expect to open a total of up to 15 sites in the United States.
