Spectrum Pharmaceuticals Provides Poziotinib Update
Spectrum will host a live webcast today at 4:30 p.m. EST/1:30 p.m. PST
HENDERSON, Nev.—December 19, 2018-- Spectrum Pharmaceuticals, Inc. (NasdaqGS: SPPI), today announced that based on a subset of data from MD Anderson’s ongoing Phase 2 study, the U.S. Food and Drug Administration (FDA) did not grant Breakthrough Therapy Designation (BTD) to poziotinib for the treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose tumors have EGFR exon 20 mutations. The company’s overall development plan and timeline for a New Drug Application (NDA) filing based on the first cohort of the ZENITH20 trial remains unchanged.

Breakthrough Therapy Designation is one of several FDA programs designed to expedite the review of drugs to treat serious or life threatening conditions. Spectrum’s BTD application included data from 30 patients from the MD Anderson Phase 2 study who had failed platinum-based chemotherapy. The data demonstrated a confirmed objective response rate of 40% and median duration of response of 6.6 months. The safety profile in this subset was consistent with historical data published on poziotinib and other tyrosine kinase inhibitors. The historical objective response rates for mutation specific NSCLC patients range between 0% and 8% with tyrosine kinase inhibitors and for non-mutation specific NSCLC patients range between 0.8% and 22.9% with other treatments.

“Our enthusiasm for poziotinib, our commitment to the program, and our overall development plan remain unchanged,” said Joe Turgeon, President and Chief Executive Officer of Spectrum Pharmaceuticals. “We will continue to work with the FDA to achieve the fastest route to approval of poziotinib based on our ZENITH20 study.”

ZENITH20 is a Spectrum-sponsored, open-label, single-arm, multi-center, global Phase 2 study evaluating more than 300 NSCLC patients with EGFR or HER2 exon 20 insertion mutations. The study consists of four cohorts, each of which is independently powered for a pre-specified statistical hypothesis.

“Poziotinib’s overall development program is robust, and the clinical profile remains very attractive in an area of high unmet need,” said Francois Lebel, M.D., F.R.C.P.C, Chief Medical Officer of Spectrum Pharmaceuticals. “Data required for the NDA filing for previously treated NSCLC patients with EGFR exon 20 insertion mutations is expected to come from an 87-patient cohort in our ZENITH20 study. We expect to complete enrollment in this cohort in the first quarter of 2019, and announce topline data in the second half of 2019.”

About Poziotinib
Poziotinib is a novel, oral Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor (EGFR TKI) that inhibits the tyrosine kinase activity of EGFR as well as HER2 and HER4. Importantly this 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 from Hanmi Pharmaceuticals to develop, manufacture, and commercialize poziotinib worldwide, excluding Korea and China. Poziotinib is currently being investigated by Spectrum and Hanmi in several mid-stage trials in multiple solid tumors.

About ZENITH20

The ZENITH20 study is Spectrum-sponsored, Phase 2, open-label, single-arm, multi-center, global study for patients with EGFR or HER2 exon 20 insertion mutations in NSCLC. It consists of four cohorts, each of which is an independent study with pre-specified statistical hypotheses and statistical power. There are two cohorts in the previously-treated setting and two in the first-line setting. The full poziotinib targeted therapy clinical program is focused on four development areas for EGFR and HER2 mutations, including previously treated NSCLC, first-line NSCLC, treatment of other solid tumors and combination therapy.
