ATNX Athenex Inc

Athenex, Inc., (NASDAQ: ATNX), a global biopharmaceutical company dedicated to the discovery, development, and commercialization of novel therapies for the treatment of cancer and related conditions announced that collaborators at the Quantum Leap Healthcare Collaborative reported today that the Company’s oral paclitaxel plus encequidar in combination with a PD-1 inhibitor and carboplatin has graduated in the triple-negative subgroup of high-risk early-stage breast cancer. Oral paclitaxel, relative to intravenous paclitaxel, was associated with less neuropathy and was not associated with an increase in febrile neutropenia. Quantum Leap Healthcare Collaborative anticipates presenting these results at upcoming national meetings in Q2 of 2023.

“We are very pleased that the Oral Paclitaxel combination regimen graduated from this prestigious program which has brought exciting and innovative treatments to neoadjuvant breast cancer patients. This study confirms our finding of less neuropathy for Oral Paclitaxel compared to intravenous paclitaxel in our metastatic breast cancer study. It’s reassuring to see that Oral Paclitaxel regimen was not associated with increased febrile neutropenia relative to the intravenous paclitaxel regimen in a well-conducted U.S. study,” said Dr. Johnson Lau, Chief Executive Officer of Athenex. “We will explore different opportunities to maximize the value of Oral Paclitaxel.”
