Description: GSK2256098, also known as GTPL7939, is a focal adhesion kinase-1 (FAK) inhibitor with potential antiangiogenic and antineoplastic activities. FAK inhibitor GSK2256098 inhibits FAK, which may prevent the integrin-mediated activation of several downstream signal transduction pathways, including ERK, JNK/MAPK and PI3K/Akt, thereby inhibiting tumor cell migration, proliferation and survival, and tumor angiogenesis. The tyrosine kinase FAK is normally activated by binding to integrins in the extracellular matrix (ECM) but may be upregulated and constitutively activated in various tumor cell types.

Additional Information

Interim Clinical trial results with GSK2256098 : 57 pts with advanced solid tumors have been treated at escalating doses ranging from 80 mg to 1500 mg BID: median age=58.8 (range 21-84). The most common tumor types include: mesothelioma (23), ovary (7), colon (3), kidney (3), and pancreas (3). MTD was determined to be 1000 mg BID. DLTs were Gr 2 proteinuria (1000 mg), Gr 2 nausea, vomiting, fatigue (1250 mg) and Gr 3 asthenia (1500 mg). Most frequent toxicities were nausea (32 pts, 56%), diarrhea (31 pts, 54%), vomiting (25 pts, 44%), decreased appetite (18 pts 32%) and asthenia (11 pts, 19%). The majority of toxicities were Gr 1-2; Gr 3 drug-related events included hypertriglyceridemia (n=2), hyperlipasemia (2), asthenia (1), increased amylase (1), and loss of consciousness (1). Few dose reductions and interruptions have occurred. Minor responses/stable disease (SD) were observed in pts with mesothelioma (-12%, 27 wks), melanoma (-26%, 54 wks), and naso/pharyngeal cancer (-31% target lesion, 30 wks) and SD in renal cell (48+ wks). In preliminary analysis of single-dose PK, exposure generally increased in a dose-proportional manner, and the geometric mean tÅ“ was 4.2 h. Accumulation was not observed with repeat dosing. Conclusions: GSK2256098 is well tolerated with evidence of clinical activity. PK supports BID dosing.  (source: J Clin Oncol 30, 2012 (suppl; abstr 3000)
