Spectrum Pharmaceuticals Announces Release of Updated Poziotinib Data From MD Anderson Phase 2 Study in Non-Small Cell Lung Cancer Patients
Data were featured in an oral presentation at the IASLC 19th World
Conference on Lung Cancer
Spectrum will host a live webcast today at 4:30 p.m. Eastern/1:30
HENDERSON, Nev.--(BUSINESS WIRE)--Sep. 24, 2018--
Spectrum Pharmaceuticals, Inc. (NasdaqGS: SPPI), a biotechnology company
with fully integrated commercial and drug development operations with a
primary focus in hematology and oncology, today announced preliminary
poziotinib data from the University of Texas, MD Anderson Cancer Center
Phase 2 non-small cell lung cancer (NSCLC) study which were released
today during an oral presentation at the IASLC 19th World Conference on
Lung Cancer hosted by the International Association for the Study of
Lung Cancer. The MD Anderson study is the single largest data set of
patients with an exon 20 mutation in EGFR or HER2.
“There are currently no approved targeted therapies for this
hard-to-treat population,” said John Heymach, M.D., Ph.D., Chairman and
Professor, Department of Thoracic/Head and Neck Medical
Oncology, University of Texas, MD Anderson Cancer Center. “For this
reason, it is especially exciting to observe that poziotinib is highly
active, with a manageable safety profile, in these heavily pre-treated
patients. The study is ongoing with nineteen EGFR patients remaining on
treatment, six of which have been on drug for longer than a year.
Poziotinib may offer a much needed option to NSCLC patients with exon 20
mutations in EGFR or HER2.”
In the interim analysis presented at the WCLC, the following
observations were made:
This phase II study demonstrates high anti-tumor activity for
poziotinib in metastatic, heavily pretreated EGFR exon 20 mutant
NSCLC, a group for which no targeted agents have proven effective to
date (other than patients bearing T790M or S768I mutations) with best
response of PR in 55% of evaluable patients (43% confirmed ORR to
date; 19 patients remain on treatment).
Median PFS 5.5m; durable responses observed with 6 treated for
>1year thus far.
Compares favorably to historical ORR rates of <8% approved TKIs
and <19% for standard of care 2L agents (docetaxel, PD-1/PD-L1
Significant activity also observed in HER2 exon 20-mutant NSCLC with
initial responses observed in 50% (6/12) evaluable patients and median
EGFR-related toxicities (including rash, diarrhea, & paronychia) were
manageable and required dose reductions in 60%. Discontinuation due to
poor tolerance was rare (3%).
Encouraging activity has prompted a confirmatory, international,
multicenter study in EGFR and HER2 exon 20 mutant NSCLC patients which
is currently enrolling (NCT03318939), including a first-line cohort,
and development of a separate pan-tumor basket study.
The poziotinib NSCLC clinical program for patients with EGFR or HER2
exon 20 insertion mutations currently consists of a Phase 2
investigator-initiated study at The University of Texas, MD Anderson
Cancer Center and a Phase 2 pivotal, Spectrum-sponsored, multi-center,
global study (ZENITH20) with active sites in the United States and
future centers planned in Canada and Europe. The overall poziotinib
clinical development program is focused on four pillars, including
previously treated NSCLC, first-line treatment of NSCLC, combination
therapy and treatment of other solid tumors.
Following the oral presentation of data, Spectrum Pharmaceuticals will
be hosting a live webcast featuring Dr. John Heymach.

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