Athenex announces results of first cohort of Phase 1b clinical trial of Oraxol
Athenex announced the completion of the first cohort of patients in its Phase 1b clinical trial of Oraxol plus CYRAMZA in gastric cancer patients that failed previous chemotherapies. Oraxol, an innovative development in the treatment of cancer, is a novel oral formulation of paclitaxel, a very effective and commonly used chemotherapy treatment for many cancers, combined with HM30181A. A previously completed Phase II clinical trial of Oraxol in the second-line treatment of gastric cancer patients showed an encouraging overall median survival of 10.7 months. The expected overall survival for advanced gastric cancer patients who have failed previous chemotherapy and do not receive second-line therapy is approximately 4.0 months. Of the six patients in the first cohort, the Oraxol and ramucirumab combination treatment was well tolerated. Grade 4 neutropenia occurred in one patient who fully recovered and there were no patient deaths. There was no neuropathy. Two patients had partial responses and three patients had stable diseases. Only one patient had progressive disease. Although early, these results are regarded as encouraging compared with previous IV paclitaxel and ramucirumab combination therapy Phase III clinical trial results. Athenex is advancing to the second cohort with Oraxol dose escalation.
