The Food and Drug Administration (FDA) has granted Fast Track designation to ATX01 for the treatment of chemotherapy-induced neuropathic pain.

ATX01 is a topical formulation of amitriptyline designed to directly inhibit pain signaling in the nerve fibers on the epidermis and dermis, while minimizing systemic absorption. In a phase 1 trial, favorable local and systemic tolerance with low systemic penetration was observed in healthy participants administered ATX01.
