A Randomized-Controlled Phase 2 Study of the MET Antibody Emibetuzumab in Combination with Erlotinib as First-Line Treatment for EGFR Mutation-Positive NSCLC Patients.

Introduction: The hepatocyte growth factor receptor mesenchymal-epithelial transition (MET) is reported to be a negative prognostic marker in EGFR-mutant NSCLC and involved in resistance to EGFR inhibitors. Emibetuzumab, a humanized immunoglobulin G4 monoclonal bivalent MET antibody, blocks ligand-dependent and ligand-independent hepatocyte growth factor/MET signaling. This phase 2 study compared erlotinib with and without emibetuzumab in first-line treatment of EGFR-mutant metastatic NSCLC.

Clozapine-induced intestinal occlusion: a serious side effect.

Aim of this article is to describe the first italian case reported in literature of a clozapine-induced intestinal occlusion with previous severe constipation in a 45-year-old male patient who had been treated with daily clozapine for 5 months because of treatment-resistant residual schizophrenia. When conservative treatment (intravenous fluids, fleet enema and rectal washout) was used and clozapine therapy was decreased, gastrointestinal symptoms rapidly improved and the patient had regular bowel motions within a week. Preventive measures (high-fiber diet, adequate fluid intake, stool softeners and exercise) was also used to ensure that clozapine therapy could be safely continued.
