About W0180

W0180 is a first-in-class antibody targeting VISTA (V-domain Ig suppressor of T cell Activation). VISTA is a negative checkpoint regulator of T cell response. VISTA is expressed within the tumor microenvironment,where its inhibition can enhance antitumor immune responses. Furthermore,an increase in VISTA expression has been reported after treatment with anti-PD1/L1 and anti-CTLA4. This confirms that VISTA may play a key role as a mechanism of resistance to the currently used immunotherapies. W0180 given to patients as a single agent or in combination with anti-PD1/L1 therapy has a potential in multiple cancer indications,including those with myeloid immunosuppressive infiltrates where the VISTA pathway is expressed.
