Mavelertinib (formerly PF-06747775; PF06747775) is a mutant-selective, orally bioactive and irreversible/covalent inhibitor of the epidermal growth factor receptor (EGFR) T790M. It has potential antineoplastic activity. As as EGFR T790M inhibitor, PF-06747775 specifically binds to and inhibits EGFR T790M, a secondarily acquired resistance mutation, which prevents EGFR-mediated signaling and leads to cell death in EGFR T790M-expressing tumor cells. Compared to some other EGFR inhibitors, PF-06747775 may have therapeutic benefits in tumors with T790M-mediated drug resistance.

Biological Activity
| ln Vitro | Selectivity against wild-type EGFR is demonstrated by mavelertinib (IC50=307 nM)[1]. Less than 50% of non-kinase targets are affected or inhibited by mavelertinib (10 μM) [1]. With an IC50 > 100 μM, mavelertinib suppresses hERG26 current[1]. |
| ln Vivo | Following oral dosing (1 in mice, 30 in rats, and 3 mg/kg in dogs), mavelertinib has low to moderate oral bioavailability (60% in mice, 11% in rats, and 66% in dogs) [1]. Intravenous injection (1 mg/kg) in small rats, rats, and dogs [1]. |
| Animal Protocol |
Animal/Disease Models: Female Nu/nu (nude) mice [1] Doses: 1 mg/kg (pharmacokinetic/PK/PK analysis) Route of Administration: Po and iv Administration Experimental Results: Oral bioavailability (60%), T1/2 (1.48 h). |

| Additional Infomation |
Mavelertinib is under investigation in clinical trial NCT02349633 (Study for Patients With NSCLC EGFR Mutations (Del 19 or L858R +/- T790M)). Mavelertinib is an orally available inhibitor of the epidermal growth factor receptor (EGFR) mutant form T790M, with potential antineoplastic activity. Mavelertinib specifically binds to and inhibits EGFR T790M, a secondary acquired resistance mutation, which prevents EGFR-mediated signaling and leads to cell death in EGFR/T790M-expressing tumor cells. Compared to some other EGFR inhibitors, PF-06747775 may have therapeutic benefits in tumors with T790M-mediated drug resistance. This agent shows minimal activity against wild-type EGFR (WT EGFR), and does not cause dose-limiting toxicities that occur during the use of non-selective EGFR inhibitors, which can inhibit WT EGFR. EGFR, a receptor tyrosine kinase mutated in many tumor cell types, plays a key role in tumor cell proliferation and tumor vascularization. |
