CAMBRIDGE, UK and CAMBRIDGE, MA, USA I July 08, 2021 I F-star Therapeutics, Inc. (NASDAQ: FSTX) (“F-star” or the “Company”), a clinical-stage biopharmaceutical company dedicated to developing next generation bispecific immunotherapies to transform the lives of patients with cancer, today announced that it has entered into an exclusive licensing agreement with AstraZeneca plc (NASDAQ: AZN) (“AstraZeneca”), under which AstraZeneca will receive global rights to research, develop and commercialize next generation Stimulator of Interferon Genes (STING) inhibitor compounds.

We are confident that AstraZeneca can maximize the value of these discovery stage compounds to benefit patients.”
