Dr. Rudolf Kwan, Athenex's Chief Medical Officer, commented, "A major component of cancer treatment consists of intravenous chemotherapy. Many oncologists are currently limited by the amount of standard intravenous chemotherapy a patient can tolerate. Oraxol is the first drug candidate from an innovative technology platform which enables the oral administration of a chemotherapy drug usually administered by the intravenous route (i.e., paclitaxel). The effect of the compound is limited to the intestinal cells, as it is not significantly absorbed in humans. Oral dosing of paclitaxel potentially provides longer drug exposure over a target drug concentration and may offer the opportunity for chronic chemotherapy, which will be evaluated for increased efficacy."
Oraxol is also being evaluated in a Phase 3 metastatic breast cancer trial in a head-to-head comparison against intravenous paclitaxel. An open-label Phase 2 study with oraxol as a monotherapy in advanced gastric cancer patients reported median overall survival of 10.7 months.
CYRAMZA is approved in the U.S. for use as a single agent or in combination with paclitaxel as a treatment for people with advanced or metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma whose cancer has progressed on or after prior fluoropyrimidine- or platinum-containing chemotherapy.
Oraxol includes a combination of the oral absorption molecule, HM30181A, which is a P-glycoprotein (P-gp) pump inhibitor, and an oral form of paclitaxel. Suppression of the P-gp pump in the gastrointestinal tract allows certain compounds (such as paclitaxel), which would normally be effluxed back into the gastrointestinal tract and excreted, to enter the bloodstream and be bioavailable via oral administration. Importantly, HM30181A is a P-gp inhibitor that is not systemically absorbed. The current lead clinical phase products include an oral formulation of paclitaxel and an oral formulation of irinotecan, which are both in multiple clinical studies globally.
About CYRAMZA® (ramucirumab)
In the U.S., CYRAMZA® (ramucirumab) is approved for use as a single agent or in combination with paclitaxel as a treatment for people with advanced or metastatic gastric (stomach) or gastroesophageal junction (GEJ) adenocarcinoma whose cancer has progressed on or after prior fluoropyrimidine- or platinum-containing chemotherapy. It is also approved in combination with docetaxel as a treatment for people with metastatic non-small cell lung cancer (NSCLC) whose cancer has progressed on or after platinum-based chemotherapy. Additionally, it is approved with FOLFIRI as a treatment for people with metastatic colorectal cancer (mCRC) whose cancer has progressed on or after therapy with bevacizumab, oxaliplatin, and a fluoropyrimidine.
There are several additional studies underway or planned to investigate CYRAMZA as a single agent and in combination with other anti-cancer therapies for the treatment of multiple tumor types. This broad global development program has enrolled more than 10,000 patients across more than 70 trials of CYRAMZA worldwide.
CYRAMZA is an antiangiogenic therapy. It is a vascular endothelial growth factor (VEGF) Receptor 2 antagonist that specifically binds and blocks activation of VEGF Receptor 2 by blocking the binding of VEGF receptor ligands VEGF-A, VEGF-C, and VEGF-D. CYRAMZA inhibited angiogenesis in an in vivo animal model.
About Gastric Cancer
The American Cancer Society estimates that 26,370 cases of gastric cancer will be diagnosed in the U.S. in 2016 (16,480 men and 9,890 women) and 10,730 people will die from this type of cancer (6,540 men and 4,190 women). Gastric cancer is much more common in other parts of the world, particularly in the Far East and less developed countries. It is the third leading cause of cancer-related deaths globally.
Founded in 2003, Athenex, Inc. is a global clinical-stage biopharmaceutical company dedicated to becoming a leader in the discovery and development of next generation drugs for the treatment of cancer. Athenex is organized around three platforms: an Oncology Innovation Platform, a U.S. Commercial Platform and a Global Supply Chain Platform. The company's Oncology Innovation Platform generates clinical candidates through an extensive understanding of human absorption biology and kinases, including novel binding sites, and through the application of its proprietary research and selection processes in the lab. Athenex's current clinical pipeline is derived from two different platform technologies called Orascovery and Src Kinase Inhibition. The Orascovery platform is based on the company's belief that the next generation of cancer treatments will be driven by oral cytotoxics allowing clinicians to potentially increase the amount of drug exposure per treatment cycle and increase the number of treatment cycles tolerated by patients. The Src Kinase inhibition platform includes small molecules addressing unmet medical needs that work through multi-mechanisms of action including inhibition of Src activities and tubulin polymerization inhibition. Athenex's several hundred employees are dedicated to delivering innovative drugs that can have a life-changing impact on cancer patients. The company has offices in: Buffalo and Clarence, New York; Cranford, New Jersey; Houston, Texas; Chicago, Illinois; Hong Kong; Taipei, Taiwan; and multiple locations in Chongqing, China.
