Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Ibudilast is a non-selective phosphodiesterase (PDE) inhibitor with anti-inflammatory properties which has shown to improve acute neurotoxicity in animal models. The study intervention will be oral ibudilast 30mg twice daily for the duration of one cycle, named Cycle B. The duration of the cycle is 2 weeks for patients receiving infusional fluorouracil with oxaliplatin (FOLFOX) and 3 weeks for patients receiving oral capecitabine with oxaliplatin (CapeOx). There is no washout period. Drug tablet return at the end of the cycle and weekly phone contact will be used to monitor adherence to the intervention.

Prevention
Comparator / control treatment
The study control is a cycle, named Cycle A, is the patient's usual chemotherapy without the addition of oral ibudilast (FOLFOX or CapeOx).
Control group
Active

Statistical methods / analysis
This trial is a pilot study, the results of which can provide rationale to perform a larger randomised control trial if positive. We based our sample size calculations assuming almost all patients receiving oxaliplatin develop acute neurotoxicity by cycle 2 and 50% develop CIPN by 3 months. We would consider ibudilast promising for further evaluation if in 20 patients, less than 10 patients develop acute neurotoxicity (as measured by OSNS).
