Spectrum Pharmaceuticals Presents Twice Daily Dosing Data for Poziotinib at the ESMO TAT Virtual Congress 2021

Spectrum Pharmaceuticals (NasdaqGS: SPPI), a biopharmaceutical company focused on novel and targeted oncology therapies, today presented results from Cohort 3 and initial twice daily (BID) dosing safety and efficacy data for poziotinib from Cohort 5 of the ZENITH20 clinical trial. These preliminary data demonstrate improved tolerability with BID dosing, reduced dose interruption compared to once daily (QD) dosing, and a reduction in treatment emergent Grade 3 or higher adverse events. The preliminary data also suggest improved anti-tumor activity with 8mg BID dosing. The presentation is part of the European Society for Medical Oncology Targeted Anticancer Therapies (ESMO TAT) Virtual Congress 2021 being held March 1-2, 2021.

“As predicted by the pharmacokinetic modeling, the 8mg BID arm is showing an improved therapeutic effect and a lowered adverse event rate in this early data,” said Francois Lebel, M.D., Chief Medical Officer of Spectrum Pharmaceuticals. “The data build on the positive results we have reported for Cohort 2 which will be the basis for our NDA submission later this year. We look forward to reporting additional data at AACR in April.”
