Array BioPharma to initiate Phase 3 trial evaluating MEK162 Array BioPharma announced that it will initiate a global Phase 3 clinical trial in patients with recurrent low-grade serous ovarian cancer during the summer of 2013. The study, called MILO, will evaluate the efficacy and safety of MEK162 compared to standard chemotherapy treatments and is designed for worldwide regulatory submissions, including with the U.S. Food and Drug Administration and the European Medicines Agency. Array invented MEK162 and licensed worldwide rights to develop and commercialize the drug to Novartis in April 2010. The MILO study follows a recent announcement by Novartis detailing plans to initiate Phase 3 trials of MEK162 in both NRAS- and BRAF-mutant melanoma and will be covered as part of the Novartis/Array co-development agreement under which costs are capped annually and in total for Array.
Piper cuts Array target by only 50c after failed trial Piper Jaffray analyst Edward Tenthoff says selumetinib for Uveal Melanoma is a small indication and represented only a small part of his valuation for Array BioPharma (ARRY). As such, after partner AstraZeneca (AZN) announced that selumetinib failed in the Phase III trial, the analyst cut his price target for Array by only 50c to $14.50. The primary drivers for Array remain binimetinib and encorafenib in NRAS and BRAF melanoma and low-grade serous ovarian cancer, the analyst tells investors in a research note. He keeps an Overweight rating on the stock.
AstraZeneca says Phase 3 study of selumetinib did not meet primary endpoint AstraZeneca (AZN) announced that the Phase 3 SUMIT study of selumetinib in combination with dacarbazine for the treatment of patients with metastatic uveal melanoma did not meet its primary endpoint of progression free survival. This combination therapy showed an adverse event profile generally consistent with current knowledge of the safety profiles of dacarbazine and selumetinib. A full evaluation of the data is ongoing. Selumetinib is a MEK inhibitor in late-stage development, with a primary Phase 3 program in second-line KRAS-mutant advanced non-small cell lung cancer in combination with docetaxel. Selumetinib is also being investigated in a Phase 3 study in differentiated thyroid cancer and in a Phase 2 registration study in patients with neurofibromatosis Type 1. Selumetinib is an oral small molecule MEK inhibitor invented by Array BioPharma (ARRY) and licensed to AstraZeneca in 2003.
