F-star Therapeutics to Present FS222 Trial-in-Progress Update at ESMO Immuno-Oncology Congress 2021 - Seite 2

Louis Kayitalire, Chief Medical Officer of F-star, said “We are encouraged by the emerging patient data on FS222, one of F-star’s four programs currently in the clinic. This has enabled us to start recruiting tumor types of interest in dose expansion cohorts to gather additional safety, pharmacokinetic, pharmacodynamic and preliminary efficacy data. We see great potential with FS222, as we believe that it is uniquely positioned to fulfill unmet medical needs in cancer with PD-L1 low expression.”  

About FS222
FS222 was designed to be a potent human CD137/PD-L1 tetravalent conditional agonist with a unique combination of high affinity PD-L1 binding, and moderate affinity, but with high avidity, binding to CD137 on activated T cells to result in optimal receptor clustering. Previously, FS222 has been shown to exhibit a favorable safety profile in preclinical safety studies.

FS222 simultaneously “releases the brake” on immune control of cancer by blocking the PD-1/PD-L1 pathway and “hits the gas” on immune activation by stimulating the CD137 pathway.
