The firm has determined that the re-examination procedure is not an appropriate format to address all the pending concerns raised by the Committee for Human Medicinal Products (CHMP).
AB Science will negotiate with EMA about the pathway to be followed to secure marketing authorization for the use of masitinib in the treatment of ALS.
In September 2016, the company filed MAA to the EU, based on the interim results from study AB10015.
