Randomized Controlled Trial Multicenter Study
Fulranumab as Adjunctive Therapy for Cancer-Related Pain: A Phase 2, Randomized, Double-Blind, Placebo-Controlled, Multicenter Study.
This randomized, double-blind (DB), placebo-controlled, phase 2 study assessed the efficacy and safety of fulranumab as a pain therapy adjunctive to opioids in terminally ill cancer patients. Ninety-eight patients were randomized (2:1) to receive one subcutaneous injection of fulranumab (9 mg) or placebo in the 4-week DB phase. Seventy-one (72%) patients entered the 48-week open-label extension phase and were administered 9 mg of fulranumab every 4 weeks. ⋯ Although no differences were seen between fulranumab and placebo groups on the primary endpoint, improvements in BPI-SF pain subscale scores and responder rates support further research of anti-nerve growth factor therapy in cancer-related pain. PERSPECTIVE: Efficacy and safety of fulranumab as adjunctive pain therapy in terminally ill cancer patients were assessed. Results suggest that anti-NGF agents may prove to be novel additions in helping to optimize pain relief in cancer patients who fail to respond adequately to opioids and other common co-analgesics.

Randomized Controlled Trial
Operant learning versus energy conservation activity pacing treatments in a sample of patients with fibromyalgia syndrome: A pilot randomized controlled trial.
This study's aim was to assess the efficacy of 2 forms of activity pacing in patients with fibromyalgia syndrome (FMS). Treatment-related changes in activity management patterns were also examined. Patients with FMS (n = 178) were randomly assigned to an operant learning (OL; delayed [n = 36] or immediate [n = 54] groups) or an energy conservation (EC; delayed [n = 35] or immediate [n = 53] groups) treatment condition. ⋯ Research to determine the extent to which these preliminary findings replicate is warranted. PERSPECTIVE: This article examines the efficacy of 2 forms of activity pacing in patients with fibromyalgia syndrome. The results suggest the possibility that operant learning may be more beneficial than energy conservation and could potentially be viewed as an effective stand-alone activity pacing treatment for patients with fibromyalgia syndrome.
