The most usually observed adverse events had been rash, palmar plantar erythrodysesthesia syndrome, pruritus, pulmonary embolism and Docetaxel staphylococcal infection.
Many of these agents have demonstrated clinical activity in both phase I and II clinical trials and are being evaluated in a number of ongoing trials inside a range of tumor forms. Most research Docetaxel have demonstrated favorable safety profiles for these agents, when used alone or in combination with other targeted agents. Of particular clinical interest, the data demonstrate activity of c MET inhibitors E7080 in EGFR resistant tumors and an increase in time to new metastasis. Inhibitors targeting multiple pathways, such as cabozantinib may have more clinical activity across a wide spectrum of tumor types. Selective inhibitors may have activity in c METdriven tumors. Combinations of these selective inhibitors and other agents such as EGFR tyrosine kinase inhibitors and VEGF inhibitors may be necessary for broader activity.
There is an increasing body of evidence that supports c MET as a key target in oncology, for example through the development of small molecules or biological inhibitors. In addition, inhibition of c MET affects downstream signal transduction with resulting biological consequences in tumor cells. The mutation or gene amplification E7080 of MET in selected clinical populations also suggests that certain patients may be exquisitely sensitive to targeted therapies that inhibit the HGF/ MET axis. c MET also has prognostic implications in patients with cancer. Firstly, overexpression of circulating cMET in patients with NSCLC has been significantly associated with early tumor recurrence and patients with adenocarcinoma and MET amplification have also demonstrated a trend for poor prognosis.
Combined VEGF and HGF/c MET signaling has also been reported to have a greater effect on the prevention of endothelial cell apoptosis, formation of capillaries in vivo, and the increase of microvessel density within tumors. For EGFR, c MET has been implicated in cooperating as a mediator E7080 of EGFR tyrosine phosphorylation and cell growth in the presence of EGFR inhibitors. MET amplification is responsible for EGFR TKI acquired resistance in approximately 20% of patients.
