NI-2601

The latter is also used in our CD47xCD19 bispecific antibody NI-1701/TG-1801, currently in phase I clinical trials (NCT03804996, NCT04806035)...NI-2601 demonstrated effective blockade of PD-1/PD-L1 interaction, and T-cell activation in vitro, similar to the anti-PD-L1 clinical benchmarks atezolizumab and avelumab...Thus, NI-2601 is able to harness Fc-effector function to eliminate PD-L1-positive tumor cells while sparing PD-L1-negative cells, such as RBC or platelets. Pharmacokinetic and tolerability studies in non-human primate are planned for 2022.
