Sialic acid is a special glycan that can be recognized by a range of surface proteins that are found primarily on innate immune cells but also on activated T cells at
E-602 is a new, first-class engineered human sialidase (Neu2)Fc fusion developed for cancer treatment
Developed by Palleon, an innovative drug company founded by 2022 Nobel Laureate in Chemistry Carolyn Bertozzi, E-602 will provide data
To support clinical development, we conducted a good laboratory-practice, one-month repeated dosing toxicity study evaluating the pharmacokinetics (PK) parameters, pharmacodynamic (PD) effects, and safety profiles of E-602 in crab-eating monkeys by weekly intravenous infusion of E-602 for a total of five doses
Despite the short half-life of E-602, the PD effect of desialylation of immune cells persists on T cells for up to 7 days, consistent with the enzymatic mechanism of action of E-602
At present, palleon has reached a strategic cooperation with Henlius Fuhong to jointly develop two bifunctional antibodies, sialidase fusion proteins, for the treatment of a variety of cancers
