Patient case: 48-year-old male with Pancreatic cancer. Genetic variant: CDK6 Amplification. Other conditions: None.

Clinical trial: Study of AZD6094 (Volitinib) in Advanced Gastric Adenocarcinoma Patients With MET Amplification as a Third-line Treatment

Summary: Volitinib is a potent and selective small molecule c-Met kinase inhibitor. Volitinib was found to inhibit c-Met kinase at the enzyme and cell levels with IC50s of 4 nM for both enzyme and Met phosphorylation in the cell. Consistent with its potent enzyme and cell activity, volitinib was found to inhibit cell growth in vitro against tumors with c-Met gene amplification in the absence of HGF stimulation with IC50s generally below 10 nM. It also potently inhibited HGF-stimulated cell proliferation against tumors with c-Met overexpression or carrying a HGF/c-Met autocrine loop.
  This study is a single-arm, phase II study of votilinib in patients with advanced gastric adenocarcinoma harboring MET amplification as a third line treatment Volitinib 800 mg will be administered orally once a day for 21 days as one cycle.
  To investigate the efficacy of volitinib in patients with advanced gastric adenocarcinoma harboring MET amplification.
