MedChemExpress - Model Cofetuzumab pelidotin -1869937-48-3

Cofetuzumab pelidotin (PF-06647020) is a PTK7-targeting ADC comprising a humanized anti-PTK7 mAb (hu6M024, IgG1) joined to an auristatin microtubule inhibitor payload, auristatin-0101 (Aur0101; HY-12522), by a cleavable valine-citrulline (vc)-based linker. Cofetuzumab pelidotin has a DAR of 4. Cofetuzumab pelidotin binds to cell-surface PTK7 with an EC50 of 1153 pM by flow cytometry. Cofetuzumab pelidotin has the potential for solid tumors research[1][2][3].

Description：Cofetuzumab pelidotin (PF-06647020) is a PTK7-targeting ADC comprising a humanized anti-PTK7 mAb (hu6M024, IgG1) joined to an auristatin microtubule inhibitor payload, auristatin-0101 (Aur0101; HY-12522), by a cleavable valine-citrulline (vc)-based linker. Cofetuzumab pelidotin has a DAR of 4. Cofetuzumab pelidotin binds to cell-surface PTK7 with an EC50 of 1153 pM by flow cytometry. Cofetuzumab pelidotin has the potential for solid tumors research.

In Vitro：Cofetuzumab pelidotin (PF-06647020) shows in vitro cytotoxic effects on PTK7 expressing cancer cell lines H446, H661 and OVCAR3 with EC50 values of 7.6, 27.5 and 105 ng/mL, respectively[1]. Cofetuzumab pelidotin (PF-06647020) (for 6 days) shows high potency and PTK7-specific cytotoxicity in a panel of cancer cell lines (A549, MDA-MB-468, KYSE-150, SKOV-3, PC9, NCI-H1975 cells) with IC50s of 0-1100 nM[2]. Cofetuzumab pelidotin is less stable with a much shorter T1/2 of less than 3 days[2].

In Vivo：Cofetuzumab pelidotin (PF-06647020; 3 mg/kg; Intraperitoneal injection twice a week for four cycles) induces striking in vivo anti-tumor effects on a subset of PDXs derived from NSCLC, OVCA and TNBC[1].
