Seattle Genetics (NASDAQ: SGEN) shares rose by 15% on Monday reporting positive data from its breast cancer treatment trial.
The Company reported positive topline results from its HER2CLIMB trial, a randomized, double-blind, placebo-controlled, active comparator pivotal trial evaluating tucatinib. The trial compared tucatinib in combination with trastuzumab and capecitabine to trastuzumab and capecitabine alone in patients with locally advanced unresectable or metastatic HER2-positive breast cancer.
According to Seattle Genetics’ press release, the trial met the primary endpoint of progression-free survival (PFS), showing that the addition of tucatinib was superior to trastuzumab and capecitabine alone, with a 46% reduction in the risk of disease progression or death.
The trial also met the two key secondary endpoints at interim analysis. The tucatinib arm demonstrated an improvement in overall survival, with a 34 %reduction in the risk of death compared to trastuzumab and capecitabine alone.
For patients with brain metastases at baseline, the tucatinib arm also demonstrated superior PFS, with a 52% reduction in the risk of disease progression or death compared to those who received trastuzumab and capecitabine alone.
“There is significant unmet medical need following treatment with trastuzumab, pertuzumab and T-DM1 in patients with metastatic HER2-positive breast cancer,” said Roger Dansey, M.D., Chief Medical Officer at Seattle Genetics.
“The addition of tucatinib to the commonly used doublet of trastuzumab and capecitabine represents a potential significant clinical advance for patients with metastatic HER2-positive breast cancer, importantly, including those with brain metastases. Based on these findings, we plan to unblind the trial and offer tucatinib to patients on the control arm. We also plan to submit a New Drug Application (NDA) to the FDA in the first quarter of 2020, with the goal of bringing a much-needed new medicine to patients,” concluded Dansey.
