The frequency, characteristics and reversibility of bortezomib‐associated peripheral neuropathy were evaluated in the phase III APEX (Assessment of Proteasome Inhibition for Extending Remissions) trial in patients with relapsed myeloma, and the impact of a dose‐modification guideline on peripheral neuropathy severity and reversibility was assessed. Patients received bortezomib 1·3 mg/m² (days 1, 4, 8, 11, eight 21‐d cycles, then days 1, 8, 15, 22, three 35‐d cycles); bortezomib was held, dose‐reduced or discontinued depending on peripheral neuropathy severity, according to a protocol‐specified dose‐modification guideline. Overall, 124/331 patients (37%) had treatment‐emergent peripheral neuropathy, including 30 (9%) with grade ≥3; incidence and severity were not affected by age, number/type of prior therapies, baseline glycosylated haemoglobin level, or diabetes history. Grade ≥3 incidence …
