The identification of biomarkers of response might speed drug development and set the premises to assist clinical practice in psychiatry. In this work, we evaluated a panel of peripheral biomarkers (including IL-6, IL-10, TNF-α, TNFRII, BDNF, CRP, MMP9 and PAI1) in depressed patients receiving paroxetine, venlafaxine, or placebo. Samples were obtained from two randomised placebo-controlled studies evaluating the efficacy and tolerability of a novel drug candidate, using either paroxetine or venlafaxine as active comparators. In both studies, the biomarker candidates were analysed in plasma collected at randomization and after 10 weeks of treatment with either placebo or active comparator (for a total of 106 and 108 subjects in the paroxetine and venlafaxine study, respectively). Data were obtained by multiplexing sandwich-ELISA system. Data were subjected to statistical analysis to assess their correlation with baseline severity and with response outcome. Increases in biomarker levels were correlated with reduction in depression severity for TNF-α, IL-6 IL-10 and CRP. Response to paroxetine treatment correlated with baseline IL-10, IL-6 and TNF-α levels, with the strongest signal being observed in males. In the venlafaxine study, a correlation was observed only between CRP level at randomisation and response, suggesting differences between the two active treatments and the two studies. Our investigations suggest that a combination of pro- and anti-inflammatory cytokines may predict response outcome in patients treated with paroxetine. The potential for IL-10, IL-6 and TNF-α as response biomarkers for a wider range of antidepressants warrants further investigations in clinical trials with other monoamine reuptake inhibitors.

The physical, social, psychological, and economic burden of opioid use disorder (OUD) is substantial. As of the year 2019, the predominant focus of OUD research was outcomes such as retention and abstinence. We report herein the effects of extended-release buprenorphine (BUP-XR), the first FDA-approved subcutaneously injected, monthly treatment for OUD, on patient-centered outcomes. Materials and methods: Patient-centered outcomes were collected during an open-label safety study of participants with OUD (NCT# 02510014) evaluating BUP-XR. Measures collected during the study included the EQ-5D-5L, SF-36v2, Treatment Effectiveness Assessment (TEA), Addiction Severity Index-Lite (ASI-Lite), employment/ insurance status questionnaire, and Medication Satisfaction Questionnaire (MSQ). Changes from baseline to end of study week 49 were analyzed using mixed models for repeated measures. "Baseline" was defined as the value collected prior to the first BUP-XR injection. Results presented are for those participants who initiated treatment on BUP-XR during the open-label study and were eligible to receive up to 12 injections. Results: Four hundred twelve participants were included in analyses; 206 participants discontinued BUP-XR prematurely. Mean EQ-5D-5L scores remained stable from baseline to end of study. Statistically significant improvements from baseline to end of study were noted for the SF-36v2 mental component summary score (difference = 5.0, 95%CI: 3.5-6.5) and 7 of 8 domain scores (P < .05 for all comparisons); the SF-36v2 physical component summary remained stable from baseline to end of study. The TEA total score (difference = 9.3 points, 95%CI: 8.0-10.5) and 4 of 4 domain scores (difference = 2-3 points per domain) significantly improved from baseline to end of study. Significant improvements (P < .05 for all comparisons) on the ASI-Lite were seen for all problem areas except alcohol use from baseline to end of study. Employment rate increased 7% whereas health insurance status remained stable from baseline to end of study. Medication satisfaction measured using the MSQ was > 88% at end of study. Conclusions: Treatment with BUP-XR monthly injections for up to 12 months in this cohort of treatment-seeking individuals with OUD led to positive PCOs and high treatment satisfaction, which correspond to personal recovery. 2017). Including patient-centered outcomes as a component of OUD

Objectives: While evidence has mounted regarding the short-term effectiveness of pharmacotherapy for opioid use disorder (OUD), little is known about longer-term psychosocial, economic, and health outcomes. We report herein 12-month outcomes for an observational study enrolling participants who had previously taken part in a long-acting buprenorphine subcutaneous injection (BUP-XR) trial for moderate to severe OUD. Methods: The RECOVER (Remission from Chronic Opioid Use: Studying Environmental and SocioEconomic Factors on Recovery; NCT03604861) study enrolled participants from 35 US community-based sites. Self-reported sustained opioid abstinence over 12 months and self-reported past-week abstinence at 3-, 6-, 9-, and 12-month visits were assessed. Multiple regression models assessed the association of BUP-XR duration with abstinence, controlling for potential confounders. Withdrawal, pain, health-related quality of life, depression, and employment at RECOVER baseline and 12-month visits were also compared to values collected before treatment in the BUP-XR trial. Results: Of 533 RECOVER participants, 425 completed the 12-month visit (average age 42 years; 66% male); 50.8% self-reported sustained 12-month and 68.0% past-week opioid abstinence. In multiple regressions, participants receiving 12-month versus ≤2-month BUP-XR treatment duration had significantly higher likelihood of sustained opioid abstinence (75.3% vs 24.1%; P = 0.001), with similar results for past-week self-reported abstinence over time. During RECOVER, participants had fewer withdrawal symptoms, lower pain, positive health-related quality of life, minimal depression, and higher employment versus pre-trial visit. Conclusions: RECOVER participants reported positive outcomes over the 12-month observational period, including high opioid abstinence and stable or improved humanistic outcomes. These findings provide insights into the long-term impact of pharmacotherapy in OUD recovery.
