Background: This is a phase II randomized study to evaluate the efficacy and safety of bortezomib and pemetrexed alone or in combination, in patients with previously treated advanced non-small-cell lung cancer (NSCLC). The primary end point was assessment of response rate. Methods: A total of 155 patients were randomized (1:1:1) to pemetrexed (500mg/m2) on day 1 plus bortezomib (1.6mg/m2) on days 1 and 8 (Arm A) or pemetrexed (500mg/m2) on day 1 (Arm B) or bortezomib (1.6mg/m2) on days 1 and 8 (Arm C) of a 21 day cycle. Response rate was assessed by investigators using Response Evaluation Criteria In Solid Tumors (RECIST) criteria and toxicity assessed by the National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) grading system. Results: Response rate was 7% in Arm A, 4% in Arm B, and 0% in Arm C; disease control rates were 73%, 62%, and 43%, respectively. Median overall survival was 8.6 months in Arm A, 12.7 months in Arm B, and 7.8 months in Arm C; time to progression was 4.0 months, 2.9 months, and 1.4 months, respectively. Most common reported adverse events ≥grade 3 were neutropenia (19%), thrombocytopenia (15%), and dyspnea (13%) in Arm A, neutropenia (10%) in Arm B, and dyspnea (13%) and fatigue (10%) in Arm C. Conclusion: In previously treated NSCLC the addition of bortezomib to pemetrexed was well tolerated but offered no statistically significant response or survival advantage versus pemetrexed alone, while bortezomib alone showed no clinically significant activity. © 2009 Elsevier Ireland Ltd.

The overproduction of nitric oxide during the biological response to inflammation by the nitric oxide synthase (NOS) enzymes have been implicated in the pathology of many diseases. By removal of the amide core from uHTS-derived quinolone 4, a new series highly potent heteroaromatic-aminomethyl quinolone iNOS inhibitors 8 were identified. SAR studies led to identification of piperazine 22 and pyrimidine 32, both of which reduced plasma nitrates following oral dosing in a mouse lipopolysaccharide challenge assay. © 2011 Elsevier Ltd.

Objective: Opioids are recommended for patients with moderate to severe pain due to osteoarthritis (OA), who do not receive adequate analgesia from nonopioid treatment. The objective of this study was to evaluate the efficacy and safety of OROS hydromorphone extended-release (ER) compared with placebo in patients with moderate to severe pain associated with OA. Methods: This was a randomized, placebo-controlled, double-blind, fixed-dose study. Patients received placebo or fixed-dose OROS hydromorphone ER (8 or 16mg). The primary efficacy measure was pain intensity score (11-point Numeric Rating Scale) at Maintenance Week 12, analyzed with baseline observation carried forward (BOCF) imputation for missing data. Results: This study did not meet the primary efficacy measure using the BOCF imputation. Study discontinuation was high (52%). When analyzed using last observation carried forward (LOCF) imputation, the prespecified alternate method, OROS hydromorphone ER 16mg provided significantly better analgesia than placebo (P=0.0009). Treatment was associated with significant improvements in patient global assessment (P=0.01), the overall Western Ontario and McMaster Osteoarthritis Index (WOMAC) (P=0.0003), and its subscales: pain (P=0.0001), stiffness (P=0.0023), and physical function (P=0.0006). Gastrointestinal adverse events, such as constipation and nausea, were common among patients receiving OROS hydromorphone ER. Conclusions: OROS hydromorphone ER failed to achieve statistical significance for the primary endpoint using the prespecified imputation method (BOCF), likely due to the high discontinuation rate associated with the fixed-dose design. When data were analyzed according to an alternate method of imputation (LOCF), OROS hydromorphone ER demonstrated statistically significant improvements in pain, stiffness, and physical function. © 2012 The Authors.

BACKGROUND: Although major depressive disorder (MDD) is associated with significant impairments in health-related quality of life (HRQOL), few studies have evaluated HRQOL dysfunction in multiple domains. This report examined the psychological, physical, and social domains in a large sample of outpatients who entered the Sequenced Treatment Alternatives to Relieve Depression (STAR&z.ast;D) trial. METHODS: The relationship of HRQOL and baseline sociodemographic and clinical features, including depressive severity, was evaluated. We assessed HRQOL with the 12-item Short Form Health Survey, the 5-item Work and Social Adjustment Scale, and the 16-item Quality of Life Enjoyment and Satisfaction Questionnaire. RESULTS: Among 2307 participants, greater depressive symptom severity was associated with poorer HRQOL. After controlling for age and depression severity, lower HRQOL was related independently to being African American or Hispanic, less educated, unemployed, divorced or separated, having public medical insurance, and to having more general medical disorders. We found impairments across all 3 domains, with low correlations between the 3 measures of HRQOL chosen, suggesting that they evaluate different and nonoverlapping aspects of function. CONCLUSION: Sociodemographically disadvantaged patients with greater general medical and depressive illness burden are at greatest risk for poorer quality of life. Distinct impairments are seen in the 3 domains of HRQOL.

Viral gene transfer or transgenic animals are commonly used technologies to alter gene expression in the adult brain, although these approaches lack spatial specificity and are time consuming. We delivered plasmid DNA locally into the brain of adult C57BL/6 mice in vivo by voltage-and current-controlled electroporation. The low current-controlled delivery of unipolar square wave pulses of 125νA with microstimulation electrodes at the injection site gave 16 times higher transfection rates than a voltage-controlled electroporation protocol with plate electrodes resulting in currents of about 400mA. Transfection was restricted to the target region and no damage due to the electric pulses was found. Our current-controlled electroporation protocol indicated that the use of very low currents resulting in applied voltages within the physiological range of the membrane potential, allows efficient transfection of nonviral plasmid DNA. In conclusion, low current-controlled electroporation is an excellent approach for electroporation in the adult brain, i.e., gene function can be influenced locally at a high level with no mortality and minimal tissue damage. © The American Society of Gene & Cell Therapy.

Immediate release (IR) hydromorphone has experienced significant misuse and abuse. An extended release (ER) hydromorphone formulation has been developed to provide sustained pain relief and may reduce the likelihood for abuse by delaying absorption. In this double-blind, placebo-controlled, randomized, 2-part crossover study, the abuse potential of single oral doses of hydromorphone ER (intact: 16-, 32-, and 64-mg; milled: 8-mg) was compared with 8-mg hydromorphone IR and placebo. After drug administration, subjects with a history of recreational opioid use completed a series of assessments, including subjective effects visual analog scales (eg, drug liking) and Addiction Research Center Inventory With Cole Modification, at several timepoints up to 48 hours postdose. Independent of formulation, maximum at-the-moment drug liking was higher for hydromorphone versus placebo. Maximum drug liking occurred earlier and was higher for 8-mg IR versus 16-mg ER but similar to 32-and 64-mg ER. Most positive effects were lower after 16-mg ER compared with other doses, including 8-mg IR. Bad drug effects were higher for hydromorphone ER, particularly the 64-mg dose. Milled 8-mg ER produced similar subjective effects to 8-mg IR. Comparison of scores after administration of 8-mg IR on 2 separate occasions showed that most assessments exhibited good test-retest reliability, although some scores declined marginally between test and retest. Delayed onset of good drug effects and prominent bad drug effects of hydromorphone ER suggest that, when administered intact, this formulation may have lower abuse potential than hydromorphone IR. © 2010 by Lippincott Williams & Wilkins.

Neuropeptide systems have been considered a major opportunity for the development of novel treatment approaches for anxiety disorders based on preclinical evidence and neurochemical alterations seen in anxiety disorders. This excitement was further facilitated by the fact that drugs acting at these systems, such as CRF1 antagonists, NK1 antagonists, NK3 antagonists or CCK2 antagonists, may have unique properties not seen with drugs affecting more classical mechanisms involved in anxiety. Consequently, there have been major efforts to develop such smallmolecule, nonpeptide receptor ligands. A number of these molecules have been tested in the clinic, either in trials where levels of anxiety served as a secondary measure, or in a few studies with patients suffering from anxiety disorders. But unfortunately, and despite all the efforts of the field as a whole, we still lack convincing clinical proof-of-concept for any of the neuropeptidergic approaches in patients. It must, therefore, be concluded that neuropeptide targets remain a promising approach for the development of the next generation drugs to treat anxiety disorders, but that they continue to be high-risk targets for drug development. © Springer-Verlag Berlin Heidelberg 2009.
