Randomized Controlled Trial Multicenter StudyEfficacy, Safety, and Tolerability of Fulranumab as an Adjunctive Therapy in Patients With Inadequately Controlled, Moderate-to-Severe Chronic Low Back Pain: A Randomized, Double-blind, Placebo-controlled, Dose-ranging, Dose-loading Phase II Study.
Fulranumab is an investigational, fully human recombinant monoclonal antibody (IgG2) that neutralizes the biological actions of human nerve growth factor. Low back pain is a common cause of noncancer chronic pain and represents one of the most significant socioeconomic health-related problems in developed countries. This randomized, double-blind, placebo-controlled study was conducted to evaluate the analgesic effect of fulranumab in patients with moderate-to-severe chronic low back pain. ⋯ Fulranumab did not demonstrate efficacy compared with placebo in patients with chronic low back pain but was generally well-tolerated. ClinicalTrials.gov identifier: NCT00973024.

Randomized Controlled TrialRescue Sedation With Intranasal Dexmedetomidine for Pediatric Ophthalmic Examination After Chloral Hydrate Failure: A Randomized, Controlled Trial.
It is a challenge to rescue ophthalmology examinations performed in children in the sedation room after initial chloral hydrate failure. Intranasal dexmedetomidine can be used in rescue sedation in children undergoing computed tomography. The present study aimed to assess the efficacy and tolerability of intranasal dexmedetomidine use in children undergoing ophthalmic examination after chloral hydrate failure. ⋯ In children undergoing ophthalmic examination, intranasal dexmedetomidine can be administered in the sedation room for rescue sedation after chloral hydrate failure, with the 2-μg/kg dose being more efficacious than the 1-μg/kg dose, as measured by success rate. ClinicalTrials.gov identifier: NCT02077712.

Randomized Controlled TrialLorcaserin in Obese and Overweight Patients Taking Prohibited Serotonergic Agents: A Retrospective Analysis.
Lorcaserin is a selective serotonin 2C receptor (5-HT2C) agonist approved in the United States for use in chronic weight management as an adjunct to a reduced-calorie diet and increased physical activity. Its pharmacologic activity is limited to 5-HT subtype 2 receptors. The potency of lorcaserin for the 5-HT2C receptor is 14-fold greater than its potency for the 5-HT2A receptor and 61-fold greater than its potency for the 5-HT2B receptor. Although 5-HT receptors have been implicated in serotonin syndrome, the precise pathogenesis is unknown. Given a theoretic risk for this syndrome in patients administered lorcaserin either alone or in combination with certain serotonergic agents (eg, selective serotonin reuptake inhibitors [SSRIs] and serotonin-norepinephrine reuptake inhibitors [SNRIs]), patients taking prohibited serotonergic agents were excluded from the Phase III clinical trials. This retrospective analysis evaluated the tolerability of lorcaserin in patients who took protocol-allowed or proscribed serotonergic agents for varying durations of up to 1 year during the BLOOM, BLOSSOM, and BLOOM-DM studies. ⋯ The concurrent use of lorcaserin and prohibited or allowed serotonergic agents did not appear to have increased the spectrum or intensity of AEs potentially associated with serotonin excess in this limited dataset. However, the sample population was too small to rule out an effect on a rare event such as serotonin syndrome. ClinicalTrials.gov identifiers: NCT00395135, NCT00603902, and NCT00603291.
