2024-11-05 Shanghai Henlius Biotech Results Latest Research into the Differentiated Mechanisms of Action of Serplulimab Published in mAbs Journal henlius.com ↗
Furthermore, the study found that the combined treatment with serplulimab and another immune checkpoint inhibitor, such as Henlius’ innovative anti-TIGIT Fc fusion protein HLX53 and anti-LAG-3 mAb HLX26, enhanced anti-tumour activity compared with serplulimab alone, which shows promise of more efficient clinical treatment options for cancer patients.
