HENDERSON, Nev.--(BUSINESS WIRE)--Spectrum Pharmaceuticals, Inc. (NasdaqGS: SPPI), a biotechnology company with fully integrated commercial and drug development operations with a primary focus in Hematology and Oncology, announced the oral presentation of interim data from a Phase 2 clinical study evaluating poziotinib in EGFR Exon 20 Mutant Non-Small-Cell Lung Cancer (NSCLC) by scientists from the MD Anderson Cancer Center which was presented in Yokohama, Japan, October 15-18, 2017. The Company will hold a conference call tomorrow, October 18th, at 8:30 a.m. EDT/5:30 a.m. PDT with Dr. John Heymach, M.D., Ph.D., 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, to discuss his study results.
“These data are remarkable for NSCLC patients with exon 20 insertion mutations,” said John Heymach, M.D., Ph.D., The University of Texas MD Anderson Cancer Center. “These patients currently have a poor prognosis, single-digit response rate on first generation tyrosine kinase inhibitors (TKI’s), and a PFS of about two months. What is truly noteworthy is that all 11 study patients who received poziotinib at a 16mg daily dose and have reached their first scan, have seen some level of tumor shrinkage. Interestingly, we have also seen evidence of CNS activity. Toxicities have included rash, diarrhea, paronychia, and mucositis consistent with those previously described for poziotinib and other TKI’s, which led to dose reduction in 55% of the patients. We believe that poziotinib specifically inhibits EGFR with exon 20 insertion mutations because it overcomes steric hindrance caused by exon 20 insertions, due to its smaller size and flexibility. To date poziotinib has shown promising results in patients with exon 20 insertion mutations and we are fortunate to be leading the efforts in the continuing development of this product.”
“We are greatly encouraged with the clinical data emerging from poziotinib and plan to pursue its clinical development expeditiously and aggressively,” said Rajesh C. Shrotriya, M.D., Chairman and Chief Executive Officer of Spectrum Pharmaceuticals. “In the near future, we plan to discuss the regulatory pathway for poziotinib with the FDA. At the same time, we are embarking upon an overall strategy for global clinical development and regulatory filings. With three promising drugs in late-stage development, Spectrum’s pipeline has never been as exciting and our prospects never as bright.”

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. Spectrum received exclusive license to develop, manufacture, and commercialize worldwide excluding Korea and China from Hanmi Pharmaceuticals. Poziotinib is currently being investigated by Spectrum and Hanmi in several mid-stage trials in multiple solid tumor indications.
