A novel pegylated bispecific antibody-drug conjugate (P-BsADC) JY207b targeting cancers co-expressing PD-L1 and CD47
(AACR 2024)
- "JY207 has demonstrated advantages in tumor penetration, internalization efficiency, without efflux post internalization, lacking Fc related toxicity, and better tumor inhibition than DS-8201a in a model positive for Her2, PD-L1 and CD47. These studies suggested favorable anti-tumor effect of JY207 both in vitro and in vivo, and its mechanism of action has been well described. These findings provide evidence for the efficacy of JY207 as a clinical treatment for patients with CD47/PD-L1 double positive cancers."

A novel pegylated bispecific antibody-drug conjugate (P-BsADCpb-adc) targeting cancers co-expressing PD-L1 and CD47
(AACR 2023)
- "Yet, in solid tumor therapies, effort for further improvement of efficacy and safety has been hindered by the poor tumor penetration of conventional IgG based ADC, low internalization efficiency, undesired efflux of ADC from tumor cells, narrow therapeutic window due to the on-target/off tumor and Fc induced toxicity, etc. To address those issues, we previously reported that the compound JY201, a Polyethylene Glycol (PEG)-based bispecific ADC (P-BsADC) targeting two epitopes of Her2, demonstrated advantages in tumor penetration, internalization efficiency, lysosome trafficking, no Fc related toxicity, and better efficacy in tumor inhibition than transtuzumab deruxtecan (Ds-8201). In vivo pharmacokinetics and toxicological studies of JY207 are being conducted in cynomolgus monkeys and are expected to show desirable results. All those findings in this study warrant JY207 as a promising candidate for the clinical development for patients with CD47/PD-L1 double positive..."
