• Abpro's pipeline targets similar indications as other companies in the immuno-oncology space, such as HER2+ breast cancer and gastric cancer, but with a focus on T-cell engagers.
• The use of proprietary platforms like DiversImmune and MultiMab is a common strategy among biotech companies to differentiate their technology and accelerate drug discovery.
