Spectrum Pharmaceuticals (Nasdaq: SPPI) announced that scientists from MD Anderson Cancer Center will be presenting data from a preclinical study evaluating poziotinib in lung cancer at the 17th International Association for the Study of Lung Cancer (IASLC) World Conference on Lung Cancer taking place in Vienna, Austria, December 4-7, 2016.

“Poziotinib has shown promising efficacy in preclinical models of non-small cell lung cancer (NSCLC) with exon 20 insertion mutations,” said John Heymach, MD, PhD, Chairman, Professor, and David Bruton Junior Chair in Cancer Research, Department of Thoracic/Head and Neck Medical Oncology, The University of Texas MD Anderson Cancer Center. “Tumors with these mutations have generally not been responsive to approved EGFR inhibitors, and there is an unmet need for better therapies for these patients. Computational modeling suggests that poziotinib may overcome steric hindrance of the drug binding pocket induced by the exon 20 insertion mutations. Based on these results, we are in the process of initiating a Phase 2 study in lung cancer that we plan to start in the near future.”

“Poziotinib has already shown promising data in breast cancer, and we are excited that it may now have application in lung cancer as well," said Rajesh C. Shrotriya, MD, Chairman and Chief Executive Officer of Spectrum Pharmaceuticals. “Lung cancer is the leading cause of cancer deaths in the world. Due to the mutations in the genes, lung cancer often becomes unresponsive to treatments. Patients who have exon 20 insertion mutations have few options, if any. We look forward to working closely with MD Anderson Cancer Center to continue development of this drug in this area of unmet medical need.”

About Poziotinib

Poziotinib is a novel, oral pan-HER inhibitor that irreversibly blocks signaling through the Epidermal Growth Factor Receptor (EGFR, HER) Family of tyrosine-kinase receptors, including HER1 (erbB1; EGFR), HER2 (erbB2), and HER4 (erbB4), and importantly, also HER receptor mutations; this, in turn, leads to the inhibition of the proliferation of tumor cells that overexpress these receptors. Mutations or overexpression/amplification of EGFR family receptors have been associated with a number of different cancers, including non-small cell lung cancer (NSCLC), breast cancer, and gastric cancer.
