Article Synopsis
- E-52862, a selective sigma-1 receptor antagonist, was tested for its effectiveness and safety in treating chronic pain conditions (CPSP and PDN) through phase 2 randomized studies involving adult patients.
- In CPSP patients, E-52862 showed a greater reduction in pain intensity compared to placebo after 4 weeks, while no significant difference was found in PDN patients likely due to a high response rate to placebo.
- Although the treatment had a higher incidence of adverse events in CPSP patients compared to placebo, overall, E-52862 was deemed tolerable and effective in providing meaningful pain relief for chronic postsurgical pain.
Background/objective: There are several questionnaires for the challenge of anticipating opioid use disorder (OUD). However, many are not specific for chronic non-cancer pain (CNCP) or have been developed in the American population, whose sociodemographic factors are very different from the Spanish population, leading to scarce translation into clinical practice. Thus, the aim of this study is to prospectively validate a predictive model for OUD in Spanish patients under long-term opioids.

Methods: A cross-sectional study was conducted in 135 CNCP outpatients with usual prescribing (TAP: n = 58, OXN: n = 77) at a tertiary-care Spanish Hospital to compare health-related quality-of-life (HRQoL) records. Health utility was derived from the EQ-5D-3L.
Opioid use disorder (OUD) is a multifaceted condition influenced by sex, genetic and environmental factors that could be linked with epigenetic changes. Understanding how these factors interact is crucial to understand and address the development and progression of this disorder. Our aim was to elucidate different potential epigenetic and genetic mechanisms between women and men that correlate with OUD under real-world pain unit conditions.

We hypothesized that CYP2D6 phenotypes and concomitant use of CYP2D6 substrates or inhibitors would correlate with opioid analgesic outcomes.
Materials And Methods: An observational cross-sectional study was conducted with 263 adult chronic non cancer pain (CNCP) patients from a real-world pain unit under long-term CYP2D6-related opioid treatment (tramadol, hydromorphone, tapentadol or oxycodone).
