Abstract
We report the outcome of a pilot, open-label study that tested the potential of lacosamide (200 mg/bi.d) as an effective and safe symptomatic treatment against acute painful oxaliplatin-induced peripheral neurotoxicity (OXAIPN). Lacosamide was introduced in 18 colorectal cancer patients with evidence of clinically significant acute, painful OXAIPN after infusion of the third course (T1) of oxaliplatin-based chemotherapy (FOLFOX4) and was maintained until completion of all 12 courses (T4). The OXA-Neuropathy Questionnaire (OXA-NQ) was used to record the severity of acute OXAIPN; the PI-NRS estimated the severity of neuropathic pain, while the chronic OXAIPN was graded with TNSc. The EuroQOL (EQ-5D) instrument was also applied. The Patient Global Impression of Change (PGIC) scale measured the lacosamide-attributed perception of change. LCM-responders were considered those with ≥50% reduction in PI-NRS and OXA-NQ scores at T4, compared to T1. Patients experienced on T1 a median number of acute OXAIPN symptoms of 4 and had a median neuropathic pain severity score of 6, which was strongly related to lower quality of life, according to EQ-VAS (P < .001). At T4, 12 patients (66.7%) were classified as responders. A significant clinical improvement was documented in the severity of acute OXAIPN and neuropathic pain in relation to lacosamide (P < .001) at T4 compared to T1, which was associated with improved EQ-VAS scores (P < .001). Twelve patients scored PGIC ≥5 (lacosamide-attributed) at T4. There were no incidences of early drop-outs for safety reasons. Lacosamide appears to be an effective and well-tolerated symptomatic treatment against acute, painful OXAIPN.
