Background: Patients with colorectal cancer treated with oxaliplatin are at risk of hypersensitivity reactions, with the incidence estimated to be 12%–20%. Coinfusion of dexamethasone and oxaliplatin could potentially reduce the incidence of these reactions, but oxaliplatin is reported to be incompatible with alkaline compounds in solution. However, in a previous retrospective study we found that the pH of a solution of dexamethasone and oxaliplatin was less than 7.4, and that hypersensitivity to oxaliplatin could have been prevented by coinfusion of dexamethasone. We aimed to evaluate the effectiveness of coinfusion of dexamethasone and oxaliplatin to prevent oxaliplatin-induced hypersensitivity reactions. Patients and methods: The AVOID trial was a prospective, multicenter, open-label, single-arm Phase II trial conducted from January to September 2013. The study included 73 patients who received capecitabine plus oxaliplatin (XELOX) or XELOX plus bevacizumab therapy for colorectal cancer. In all patients, oxaliplatin was administered in combination with dexamethasone. The primary outcome measure was the presence of hypersensitivity reactions. Results: Hypersensitivity reactions occurred in three patients (4.1%); all three experienced a cutaneous reaction (grade 1 erythema). None of the 73 patients developed respiratory symptoms, ocular symptoms, or anaphylaxis. Grade 3 or higher hemotoxicity occurred in 13.7% of the patients and grade 3 or higher nonhematological toxicity occurred in 13.7%. The response rate to treatment was 64.4%. Conclusion: The coinfusion of dexamethasone and oxaliplatin effectively reduced oxaliplatin-induced hypersensitivity reactions in patients with colorectal cancer. This approach should be considered for all patients treated with oxaliplatin, allowing treatment to be completed as planned.
