Chemical Information

Defactinib

Defactinib is a small molecule kinase inhibitor targeted against focal adhesion kinase (FAK) and proline-rich tyrosine kinase-2 (Pyk2), the two members of the FAK family of nonreceptor tyrosine kinases. FAK is important for the integrin-mediated activation of several downstream signal transduction pathways, including those involving RAS/MEK/ERK and PI3K/Akt, and its upregulation is a key resistance mechanism to MAPK inhibitors, facilitating tumor cell proliferation and survival in the absence of MAPK signaling. Defactinib was approved by the US FDA in May 2025 in a co-package alongside [avutometinib] (called Avmapki Fakzynja) for the treatment of recurrent KRAS-mutated low-grade serous ovarian cancer.
