Lidocaine for Oxaliplatin-induced Neuropathy

"Intravenous lidocaine will be dosed as a brief 1 mg/kg infusion (based on Ideal Body Weight (IBW)) over 10 minutes, followed by a 0.04 mg/kg/min infusion over additional 120 minutes, resulting in a total dose of 5.8 mg/kg IBW.~If this dose is tolerable in four consecutive sessions of mFOLFOX6 in six or more of the eight patients in the tolerability phase, we will initiate the randomized efficacy pilot study."

Dextrose 5% in water will be administered as active comparator.

"Each cycle (repeated every 14 days):~Oxaliplatin 85mg/m2 IV over 2h, Leucovorin 400 mg/m2 IV over 2h, 5-FU 400mg/m2 IV bolus, followed by a 1200mg/m2/day continuous infusion for 2 days."
