Addressing challenges of clinical trials in acute pain: The Pain Management of Vaso-occlusive Crisis in Children and Young Adults with Sickle Cell Disease Study

摘要

Background/aims: Neuropathic pain is a known component of vaso-occlusive pain in sickle cell disease; however, drugs targeting neuropathic pain have not been studied in this population. Trials of acute pain are complicated by the need to obtain consent, to randomize participants expeditiously while optimally treating pain. We describe the challenges in designing and implementing the Pain Management of Vaso-occlusive Crisis in Children and Young Adults with Sickle Cell Disease Study (NCT01954927), a phase II, randomized, double-blind, placebo-controlled trial to determine the effect of gabapentin for vaso-occlusive crisis.
