30 [-0.66, 0.07; P=0.1117]), preventing formal testing of key secondary endpoints for this dose. The proportion of patients with ≥50% improvement in LBPI at week 16 was 37.4% in the placebo group, 43.3% in the tanezumab 5mg group (Odds ratio [95% CI] vs placebo = 1.28 [0.97, 1.70; P=0.0846]) and 46.3% in the tanezumab 10mg group (Odds ratio [95% CI] vs placebo = 1.45 [1.09, 1.91; P=0.0101]). Navitoclax molecular weight Prespecified joint safety events were more frequent with tanezumab 10mg (2.6%) than tanezumab 5mg (1.0%), tramadol (0.2%), or placebo (0%). Seven patients, all in the tanezumab 10mg group (1.4%), underwent total joint replacement. In conclusion, tanezumab 10mg significantly improved pain and function versus placebo in patients with difficult-to-treat CLBP. Tanezumab was associated with a low rate of joint safety events, some requiring joint replacement.

Dopamine release in the nucleus accumbens (NAc) influences behavior through both tonic and phasic signaling. Tonic dopamine levels are hypothesized to inversely regulate phasic signals via dopamine D2 receptor feedback inhibition. We tested this hypothesis directly in the context of ongoing pain. Tonic and phasic dopamine signals were measured using fast-scan controlled-adsorption voltammetry and fast-scan cyclic voltammetry, respectively, in the NAc shell of male rats with standardized levels of anesthesia. Application of capsaicin to the cornea produced a transient decrease in tonic dopamine levels. During the pain-induced hypodopaminergic state, electrically evoked phasic dopamine release was significantly increased when compared to baseline evoked phasic release. A second application of capsaicin to the same eye had a lessened effect on tonic dopamine suggesting desensitization of TRPV1 channels in that eye. Capsaicin treatment in the alternate cornea, however, again produced coincident decreased dopaminergic tone and increased phasic dopamine release. These findings occurred independently of stimulus lateralization relative to the hemisphere of dopamine measurement. Our data show that (a) the mesolimbic dopamine circuit reliably encodes acute noxious stimuli; (b) ongoing pain produces decreases in dopaminergic tone; and (c) pain-induced decreases in tonic dopamine correspond to augmented evoked phasic dopamine release. Enhanced phasic dopamine neurotransmission resulting from salient stimuli, may contribute to increased impulsivity and cognitive deficits often observed in conditions associated with decreased dopaminergic tone, including Parkinson's disease and chronic pain.Cancer cells secrete pro-nociceptive mediators that sensitize adjacent sensory neurons and cause pain. Identification and characterization of these mediators could pinpoint novel targets for cancer pain treatment. In the present study we identified candidate genes in cancer cell lines that encode for secreted or cell surface proteins that may drive nociception. To undertake this work, we utilized an acute cancer pain mouse model, transcriptomic analysis of publicly available human tumor-derived cell line data, and a literature review. Cancer cell line supernatants were assigned a phenotype based on evoked nociceptive behavior in an acute cancer pain mouse model. We compared gene expression data from nociceptive and non-nociceptive cell lines. Our analyses revealed differentially expressed genes (DEGs) and pathways; many of the identified genes were not previously associated with cancer pain signaling. Epidermal growth factor receptor (EGFR) and disintegrin metalloprotease domain 17 (ADAM17) were identified as potential targets among the DEGs. We found that the nociceptive cell lines contained significantly more ADAM17 protein in the cell culture supernatant compared to non-nociceptive cell lines. Cytoplasmic EGFR was present in almost all (>90%) tongue primary afferent neurons in mice. Monoclonal antibody against EGFR, cetuximab, inhibited cell line supernatant-induced nociceptive behavior in an acute oral cancer pain mouse model. We infer from these data that ADAM17-EGFR signaling is involved in cancer mediator-induced nociception. The differentially expressed genes and their secreted protein products may serve as candidate therapeutic targets for oral cancer pain and warrant further evaluation.One of the potential mechanisms of motor cortex stimulation by non-invasive brain stimulation (NIBS) effects on pain is through the restoration of the defective endogenous inhibitory pain pathways. However, there is still limited data on quantitative sensory testing (QST), including conditioned pain modulation (CPM), supporting this mechanism. This systematic review and meta-analysis aimed to evaluate the effects of non-invasive motor cortex stimulation on pain perception as indexed by changes in QST outcomes. Database searches were conducted until July 2019 to included randomized controlled trials that performed sham-controlled NIBS on the motor cortex in either healthy and/or pain population and assessed the QST and CPM. Quality of studies was assessed through the Cochrane tool. We calculated the Hedge's effect sizes of QST and CPM outcomes, their 95% confidence intervals (95% CI) and performed random-effects meta-analyses. Thirty-eight studies were included (1178 participants). We found significant increases of pain threshold in healthy subjects (ES=0.16, 95% CI=0.02 to 0.31, I=22.2%) and pain population (ES=0.48, 95% CI=0.15 to 0.80, I=68.8%); and homogeneous higher CPM effect (pain ratings reduction) in healthy subjects (ES=-0.39, 95% CI=-0.64 to -0.14, I2=17%) and pain population (ES=-0.35, 95% CI=-0.60 to -0.11, I2=0%) in active NIBs group compared with sham. These results support the idea of top-down modulation of endogenous pain pathways by motor cortex stimulation as one of the main mechanisms of pain reduction assessed by QST, which could be a useful predictive and prognostic biomarker for chronic pain personalized treatment with NIBS.
