"OBI-992 demonstrated superiority over other TROP2 ADCs in pre-clinical studies. It is a solid validation of the unique advantages of Biosion's SynTracer^® platform to identify fit-for-purpose antibodies for the development of novel ADC therapies. We are excited about this innovative treatment and making a meaningful difference for patients worldwide."

OBI Pharma plans to enroll patients with advanced solid tumors, including non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), and gastric cancer (GC), although several other cancers are also potential targets.
