Immune's bertilimumab, a first in class monoclonal antibody, is being evaluated clinically to address unmet medical needs in multiple severe disease indications. EpiCept's Amiket™ has clinical data in over 1600 patients in various neuropathies, Fast Track designation and Phase III Special Protocol Assistance from the U.S. Food and Drug Administration as well as a defined clinical path through the European Medicines Agency for the treatment of chemotherapy induced neuropathic pain."
