Mavelertinib is a selective, orally available and irreversible EGFR tyrosine kinase inhibitor (EGFR TKI), with IC50s of 5, 4, 12 and 3 nM for Del, L858R, and double mutants T790M/L858R and T790M/Del, respectively. Mavelertinib can be used for the research of non-small-cell lung cancer (NSCLC)[1][2][3][4].
Mavelertinib exhibits selectivity over wild-type EGFR (IC50=307 nM)[1].Mavelertinib (10 μM) exhibits less than 50% e?ect or inhibition against all nonkinase targets[1].Mavelertinib inhibits the hERG26 current with an IC50 > 100 μM[1].
Mavelertinib exhibits low to moderate oral bioavailability (mouse 60%, rat 11%, dog 66%) following oral administration (mouse 1, rat 30, dog 3 mg/kg)[1].Mavelertinib exhibits short plasma half-lives (mouse 0.56, rat 0.28, dog 1.3 h) due to moderate to high plasma clearance (mouse 53, rat 49, dog 12 mL/min/kg) and low steady-state volume of distribution (mouse 1.48, rat 0.66, dog 0.94 L/kg) following intravenous administration (1 mg/kg to mouse, rat and dog)[1].

Repurposing the Kinase Inhibitor Mavelertinib for Giardiasis Therapy
Antimicrob Agents Chemother 2022 Jul 19;66(7):e0001722.PMID:35703552DOI:10.1128/aac.00017-22.
A phenotypic screen of the ReFRAME compound library was performed to identify cell-active inhibitors that could be developed as therapeutics for giardiasis. A primary screen against Giardia lamblia GS clone H7 identified 85 cell-active compounds at a hit rate of 0.72%. A cytotoxicity counterscreen against HEK293T cells was carried out to assess hit compound selectivity for further prioritization. Mavelertinib (PF-06747775), a third-generation epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), was identified as a potential new therapeutic based on indication, activity, and availability after reconfirmation. Mavelertinib has in vitro efficacy against metronidazole-resistant 713-M3 strains. Other EGFR-TKIs screened in follow-up assays exhibited insignificant inhibition of G. lamblia at 5 μM, suggesting that the primary molecular target of Mavelertinib may have a different mechanistic binding mode from human EGFR-tyrosine kinase. Mavelertinib, dosed as low as 5 mg/kg of body weight or as high as 50 mg/kg, was efficacious in the acute murine Giardia infection model. These results suggest that Mavelertinib merits consideration for repurposing and advancement to giardiasis clinical trials while its analogues are further developed.
Beyond Osimertinib: The Development of Third-Generation EGFR Tyrosine Kinase Inhibitors For Advanced EGFR+ NSCLC
J Thorac Oncol 2021 May;16(5):740-763.PMID:33338652DOI:10.1016/j.jtho.2020.11.028.
Single-agent osimertinib is the standard of care for the first-line treatment of advancedEGFR+ NSCLC and remained the only marketed third-generation EGFR tyrosine kinase inhibitor (TKI) until March 2020 when almonertinib (HS-10296) was approved in the People's Republic of China for the treatment of advanced EGFR T790M+ NSCLC based on a phase 2 expansion study of a phase 1/2 trial. In this review, we profiled many of the third-generation EGFR TKIs in late-stage clinical development (e.g., almonertinib, lazertinib, alflutinib1, rezivertinib, ASK120069, SH-1028, D-0316, and abivertinib) based on their interim results from phase 1 and phase 2 trials, and included the designs of the phase 3 trials and their chemical structures when publicly available. We also listed other third-generation EGFR TKIs in pipeline development based on the search of clinical trial registration websites. In addition, we summarized the results of clinical trials that previously reported third-generation EGFR TKIs (rociletinib, olmutinib, nazartinib, Mavelertinib), including phase 3 results of rociletinib and naquotinib. We further profiled combination clinical trial design of the third-generation EGFR TKIs including FLAURA2 (NCT04035486), MARIPOSA (NCT04487080), ACROSS1 (NCT04500704), and ACROSS2 (NCT04500717) that if positive can potentially usher in the next standard of care for advanced EGFR+ NSCLC.
Novel Third-Generation EGFR Tyrosine Kinase Inhibitors and Strategies to Overcome Therapeutic Resistance in Lung Cancer
Cancer Res 2019 Feb 15;79(4):689-698.PMID:30718357DOI:10.1158/0008-5472.CAN-18-1281.
EGFR-activating mutations are observed in approximately 15% to 20% of patients with non-small cell lung cancer. Tyrosine kinase inhibitors have provided an illustrative example of the successes in targeting oncogene addiction in cancer and the role of tumor-specific adaptations conferring therapeutic resistance. The compound osimertinib is a third-generation tyrosine kinase inhibitor, which was granted full FDA approval in March 2017 based on targeting EGFR T790M resistance. The compound has received additional FDA approval as first-line therapy with improvement in progression-free survival by suppressing the activating mutation and preventing the rise of the dominant resistance clone. Drug development has been breathtaking in this space with other third-generation compounds at various stages of development: rociletinib (CO-1686), olmutinib (HM61713), nazartinib (EGF816), naquotinib (ASP8273), Mavelertinib (PF-0647775), and AC0010. However, therapeutic resistance after the administration of third-generation inhibitors is complex and not fully understood, with significant intertumoral and intratumoral heterogeneity. Repeat tissue and plasma analyses on therapy have revealed insights into multiple mechanisms of resistance, including novel second site EGFR mutations, activated bypass pathways such as MET amplification, HER2 amplification, RAS mutations, BRAF mutations, PIK3CA mutations, and novel fusion events. Strategies to understand and predict patterns of mutagenesis are still in their infancy; however, technologies to understand synthetically lethal dependencies and track cancer evolution through therapy are being explored. The expansion of combinatorial therapies is a direction forward targeting minimal residual disease and bypass pathways early based on projected resistance.
Complex Crystal Structures of EGFR with Third-Generation Kinase Inhibitors and Simultaneously Bound Allosteric Ligands
ACS Med Chem Lett 2020 Nov 5;11(12):2484-2490.PMID:33335671DOI:10.1021/acsmedchemlett.0c00472.
Osimertinib is a third-generation tyrosine kinase inhibitor (TKI) and currently the gold-standard for the treatment of patients suffering from non-small cell lung cancer (NSCLC) harboring T790M-mutated epidermal growth factor receptor (EGFR). The outcome of the treatment, however, is limited by the emergence of the C797S resistance mutation. Allosteric inhibitors have a different mode of action and were developed to overcome this limitation. However, most of these innovative molecules are not effective as a single agent. Recently, mutated EGFR was successfully addressed with osimertinib combined with the allosteric inhibitor JBJ-04-125-02, but surprisingly, structural insights into their binding mode were lacking. Here, we present the first complex crystal structures of mutant EGFR in complex with third-generation inhibitors such as osimertinib and Mavelertinib in the presence of simultaneously bound allosteric inhibitors. These structures highlight the possibility of further combinations targeting EGFR and lay the foundation for hybrid inhibitors as next-generation TKIs.
