About SBT6050

SBT6050 is the first of a new class of targeted immuno-oncology agents designed to direct a TLR8 agonist linker-payload to activate myeloid cells in tumors expressing moderate to high levels of HER2. TLR8 is expressed in myeloid cell types prevalent in human tumors and TLR8 agonism can activate a broad spectrum of anti-tumor immune mechanisms, including pathways involved in the innate and adaptive immune response. SBT6050 was specifically designed to bind to the HER2 sub-domain II, the pertuzumab epitope, to enable combinations with trastuzumab-based therapies. SBT6050 is currently being evaluated in a Phase 1/1b trial in patients with advanced or metastatic HER2-expressing or amplified solid tumors.
