Clin Ther. 2021 May 28:S0149-2918(21)00127-2. doi: 10.1016/j.clinthera.2021.03.015. Online ahead of print.ABSTRACTPURPOSE: Mirogabalin besylate has been approved in several countries to treat peripheral neuropathic pain. This pooled analysis, using data from the two pivotal Phase III studies in Asian patients with diabetic peripheral neuropathic pain and post-herpetic neuralgia, aimed to provide clinicians with more detailed and precise information relating to mirogabalin's safety and efficacy.METHODS: Data were pooled from 2 multicenter, double-blind, placebo-controlled, parallel-group, 14-week treatment studies of mirogabalin conducted at ∼350 study sites (Japan, South Korea, Taiwan, Singapore, Malaysia, and Thailand). Eligible patients in both studies were randomized in a 2:1:1:1 ratio, stratified according to a baseline average daily pain score (ADPS) of <6 or ≥6, to placebo, mirogabalin 15-mg once daily (QD), mirogabalin 10-mg twice daily (BID), or mirogabalin 15-mg BID treatment groups. Safety was assessed based on treatment-emergent adverse events identified from the adverse events collected throughout both studies. The primary efficacy end point of both studies was the change from baseline in ADPS at week 14.FINDINGS: In total, 1587 patients (824 with diabetic peripheral neuropathic pain; 763 with post-herpetic neuralgia) who received at least 1 dose of study drug were analyzed (633 received placebo, 954 treated with mirogabalin). Treatment-emergent adverse eve...
