Athenex Announces Licensing Agreement with PharmaEssentia for Rights to Oradoxel (Oral Docetaxel) in Certain Asian Territories

BUFFALO, N.Y., Nov. 29, 2018 (GLOBE NEWSWIRE) -- 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, today announced that it has entered into an agreement with PharmaEssentia Corporation (Taipei Exchange:6446) to license the rights to develop and commercialize Athenex’s Oradoxel in Taiwan, Singapore and Vietnam. The existing licensing agreement for Oraxol (oral paclitaxel) and Oratecan (oral irinotecan) with PharmaEssentia is being expanded to account for additional considerations, including milestone payments, for Oradoxel (oral docetaxel). In December 2013, Athenex and PharmaEssentia entered into a license agreement, pursuant to which PharmaEssentia was granted a license to develop and commercialize Oraxol and Oratecan in Taiwan and Singapore. The agreement was amended in December 2016 to also include Vietnam in the territories covered by the license. 

Under the terms of the expanded agreement, which includes Oradoxel, Athenex will receive a cash payment as well as the potential to receive additional milestone payments for certain development and regulatory milestones of Oradoxel in the territories. PharmaEssentia will be responsible for all activities and expenses relating to clinical development, regulatory approval, and commercialization of Oradoxel in the territories.

Docetaxel is an anti-cancer chemotherapeutic agent that is used widely in the treatment of breast, prostate, gastric, head and neck, and lung cancers. Oradoxel is an oral formulation of Docetaxel combined with HM30181A, a novel gastrointestinal tract specific P-glycoprotein pump inhibitor. Oradoxel is currently in Phase I clinical studies in the U.S. and New Zealand, and is ready to advance to Phase II with studies expected to begin in the first half of 2019.

Dr. Kochung Lin, Chief Executive Officer of PharmaEssentia, commented, “We are excited with the encouraging results so far from clinical trials of Athenex’s Orascovery drug candidates, particularly Oraxol. The potential of oral chemotherapy drugs to improve efficacy and safety, and improve patients’ quality of life, cannot be overstated. Athenex has generated promising Phase I data with both Oratecan and Oradoxel, and we are pleased to participate in the development of these exciting products in Taiwan, Singapore and Vietnam to help realize the full potential of this platform. We have been impressed by the Athenex team in their execution and are delighted to continue and expand our excellent partnership with the addition of Oradoxel.”
           
Dr. Johnson Lau, Chief Executive Officer and Chairman of Athenex, stated, “This agreement builds on our longstanding relationship with PharmaEssentia. PharmaEssentia has demonstrated strong commitment to cancer drug research and development, and we are confident they have the capabilities for successfully delivering Oradoxel to patients in the licensed territories.”

The Orascovery platform was initially developed by Hanmi Pharmaceuticals and licensed exclusively to Athenex for all major worldwide territories except Korea, which is retained by Hanmi.
