BACKGROUND: In antidepressant trials for pediatric patients with depression or anxiety disorders, the risk of suicidal events and other severe psychiatric adverse events such as aggression and agitation is increased with antidepressants relative to placebo. OBJECTIVE: To examine whether largely mentally healthy adolescents treated for a non-psychiatric condition are also at increased risk of suicidality and other severe psychiatric disorders. METHODS: This is a re-analysis of a placebo-controlled duloxetine trial for juvenile fibromyalgia based on the main journal article and additional data published in the online supplementary material and on ClinicalTrials.gov. Both serious adverse events related to psychiatric disorders and adverse events leading to treatment discontinuation were defined as severe treatment-emergent psychiatric adverse events. RESULTS: We found that a significant portion of adolescents had treatment-emergent suicidal ideation and behaviour as well as other severe psychiatric adverse events with duloxetine, but no such events were recorded on placebo. The incidence of severe treatment-emergent psychiatric adverse events was statistically significantly higher with duloxetine as compared to placebo. CONCLUSIONS: Antidepressants may put adolescents at risk of suicidality and other severe psychiatric disorders even when the treatment indication is not depression or anxiety.

Abstract Background SPR720 (phosphate pro-drug of SPR719) is a novel aminobenzimidazole bacterial DNA gyrase (GyrB) inhibitor in development for non-tuberculous mycobacterial lung disease (NTM-LD) and pulmonary tuberculosis. SPR719 has broad-spectrum activity versus clinically relevant mycobacteria in vitro and in murine and hollow fiber (HF) infection models. In this first-in-human single ascending dose (SAD) /multiple ascending dose (MAD) study, the safety, tolerability and pharmacokinetics (PK) of SPR720/SPR719 were evaluated in healthy volunteers. Methods This was a Phase 1 randomized, double-blind, placebo-controlled trial with 7 SAD cohorts (including a food effect cohort) and 5 MAD cohorts. Healthy volunteers (n=8/cohort, 3:1 randomization) received SPR720 or placebo in single oral doses of ranging from 100 mg to 2000 mg or repeat total daily doses ranging from 500 mg to 1500 mg for 7 or 14 days. Safety monitoring and PK sampling occurred throughout the trial. Plasma and urine concentrations of SPR720/SPR719 were measured by validated LC-MS/MS methods. PK parameters were calculated using non-compartmental analysis. Results A total of 96 subjects (including 8 healthy elderly subjects, age ≥ 65 years) were randomized and received study drug. SPR720 was well-tolerated at daily doses up to 1000 mg for up to 14 days. Across SAD/MAD cohorts, the most common adverse events were gastrointestinal (nausea, vomiting and diarrhea) and headache, all of mild or moderate severity and dose dependent. No serious adverse events were reported. Across SAD cohorts, a dose proportional and greater-than-dose proportional increase in SPR719 plasma Cmax and AUC0-24, respectively were observed. SPR720 was rapidly absorbed with a mean SPR719 t1/2 of 2.9-4.5 h. Dosing with food decreased SPR719 plasma AUC by ~20%. No clinically meaningful effect of age on plasma AUC was observed. In the MAD cohorts, SPR719 plasma exposure declined approximately 40% between Day 1 and Day 7, suggesting induction of an elimination pathway. However, plasma AUC0-24 was similar at Days 7 and 14. Conclusion Together with HF pharmacodynamic data, human PK and safety data for SPR720 suggest that predicted therapeutic exposures can be attained with a well-tolerated once-daily dose. Further evaluation in a Phase 2 NTM-LD trial is planned.

13001 Background: Pertuzumab (P), a humanized HER2 antibody, represents a new class of targeted agents called HER dimerization inhibitors (HDIs). P inhibits dimerization of HER2 with EGFR, HER3 and HER4, and subsequently inhibits signaling through MAP and PI3 kinases. Single agent P has demonstrated clinical benefit in advanced OC (ASCO 2005 abstract #5051). Methods: 40 pts with platinum-resistant OC (progressed within 6 months of receiving a platinum-based chemotherapy) were enrolled in this 1:1 randomized, double blind, placebo controlled trial of gemcitabine with or without P. Gemcitabine was administered IV on day 1 and 8 at 800 mg/m2 of a 21 day cycle. Blinded placebo or 420 mg P was administered IV on day 1. Gemcitabine was dose reduced for neutropenia or thrombocytopenia. P was not dose reduced. Results: 40 pts have been enrolled and treated with at least 1 cycle of gemcitabine in combination with blinded study drug. The median age was 58.5 (range 18–82); 26 had PS ECOG 0, 13 ECOG 1, 1 ECOG 2. The most common grade 3/4 events were neutropenia in 7 pts (17.5%), thrombocytopenia in 6 pts (15%), small bowel obstruction in 4 pts (10%), constipation in 3 pts (7.5%) and elevated ALT in 3 pts (7.4%). There was one grade 3 diarrhea, but no grade 3 or 4 rash. There were 4 serious adverse events (SAEs) attributed to study drug. These were a pleural effusion, thrombocytopenia, febrile neutropenia, and a deep vein thrombosis. Nine pts required one or two dose reductions of gemcitabine for hematological toxicity. Of 29 pts with post-baseline echo or MUGA values obtained, no pt had LVEF drop to <50%. The adverse events evaluated after 40 pts did not meet the prespecified criteria to call for an independent safety monitoring board evaluation of unblinded data. Conclusions: Preliminary safety data indicate that pertuzumab or placebo combined with gemcitabine is well tolerated with no unexpected additive toxicity. The nature and frequency of the adverse events are similar to what has been observed with either single agent gemcitabine or P. Updated data will be presented at ASCO. [Table: see text]

Abstract Abstract 640 Background: ALD518 is a humanized, desialyated anti-IL-6 antibody being developed for the treatment of cancer-related anemia, cachexia and fatigue. The primary objective of the study was to determine the efficacy and safety of ALD518 in patients with advanced NSCLC. Secondary objectives examined hematologic parameters. Methods: 124 patients with NSCLC, ECOG 0–3, weight loss in the preceding 3 months of >5% body weight, hemoglobin (Hb) >7g/dL, and C-reactive protein (CRP) >10mg/L were dosed. Patients were randomized to 1 of 4 groups (n~30/group). Placebo or ALD518 80mg, 160mg, or 320mg was administered intravenously every 8 weeks. Pts were followed up for 24 weeks. Data included hematologic parameters, clinical chemistry, CRP, D-dimer, lean body mass and adverse events (AEs). Quality of life data included the FACIT-F, FACT-L, and FAACT questionnaires. Data presented in this abstract relates to the safety and hematology results. Results: 29 pts completed the study treatments and evaluations, 38 failed to complete every visit, 52 died of progressive disease, and 5 withdrew because of adverse events. There were no dose limiting toxicities (DLTs), infusion reactions, or anti-idiotypic antibody responses to ALD518 observed in the study. 84 pts had serious AEs of which 1 was deemed to be possibly related to administration of ALD518 (rectal hemorrhage). The majority of the serious adverse events were due to progression of the NSCLC. Six patients had a CTC grade 4 change in laboratory safety data during the study. Four patients experienced a grade 4 hypercalcemia: 1 (3.6%), 2 (6.1%), and 1 (3.2%) in the ALD518 80mg, 160mg and placebo groups, respectively, and there was 1 patient with grade 4 GGT elevation (placebo) and 1 patient with grade 4 hypokalemia (ALD518 160mg). There were no treatment related differences in vitals sign or 12-lead ECG data. The mean (±SD) values for Hb, hematocrit (Hct), mean corpuscular Hb (MCH) and platelet counts are listed below: 38/93 pts treated with ALD518 and 10/31 given placebo had a pre-dose Hb =< 11g/dL. 24 of these pts on ALD518 and 7 of these pts on placebo remained in the study at week 4. 14/24 pts on ALD518 and 0/7 on placebo had raised their Hb from =< 11g/dL to >= 12g/dL. Conclusions: ALD518 increased Hb, Hct, MCH in NSCLC pts and raised Hb to >= 12g/dL in 58% of pts with a Hb =< 11g/dL at baseline. There was also a modest fall in platelet count observed in patients treated with ALD518 but no patients had a CTC grade 4 thrombocytopenia and only one patient (ALD518 160mg group) had a grade 3 thrombocytopenia at one time point. There were no major safety signals related to the administration of ALD518. Further study of ALD518 as a novel non-erythropoietic stimulating agent for cancer-related anemia is warranted.

Ocular anti-vascular endothelial growth factor (VEGF) therapy represents a major breakthrough in the treatment of patients with neovascular age-related macular degeneration (nvAMD). The anti-VEGF agents, ranibizumab and bevacizumab, are both widely used in the treatment of nvAMD although bevacizumab has not yet received regulatory approval for intraocular use. Bevacizumab costs considerably less than ranibizumab when administered as an intraocular injection, which has led to widespread use and studies comparing the efficacy and safety of the two drugs. Bevacizumab shares identical pharmacology with ranibizumab although structural differences result in differences in receptor affinity and rates of drug clearance. While estimates of the vitreous half-life of ranibizumab vary, it is shorter than that of bevacizumab. Furthermore, the serum half-life of bevacizumab is about 20 days, more than twice that of ranibizumab and this has led to speculation that it may present a greater risk of systemic adverse effects. Considerable clinical trial evidence exists relating to the efficacy and safety of ranibizumab. The Comparison of age-related macular degeneration treatments trials (CATT) study of the two drugs found efficacy to be equivalent for the as needed versus as needed and monthly versus monthly comparisons. Ranibizumab as needed was equivalent to monthly ranibizumab, though the bevacizumab as needed was not equivalent to monthly bevacizumab. A greater number of serious adverse events (SAEs) occurred with bevacizumab. However, the study was insufficiently powered to identify differences in drug-related adverse events. Intravitreal injection of bevacizumab is associated with a low but significant risk of acute intraocular inflammation, shown to result in significant visual loss in some patients. Finally, there are issues related to fractionating of bevacizumab that has lead to sporadic cases of blindness worldwide. The increased risk for both systemic and ocular adverse events may influence the cost-effectiveness ratio of the two drugs based on health economic models. Further comparative studies and continuous monitoring of safety data are required to examine the incidence of adverse events.

Objectives: Alzheimer's disease (AD) is the most common cause of dementia and it is associated with increased mortality. The use of antipsychotics is common among the elderly, especially in those with dementia. Evidence suggests an increased risk of mortality associated with antipsychotic use. Despite the short-term benefit of antipsychotic treatment to reduce the behavioral and psychological symptoms of dementia, it increases the risk of mortality in patients with AD. Our aim is to discuss the findings from the literature about risk of mortality associated with the use of antipsychotics in AD.Methods: We searched Internet databases indexed at MEDLINE using following MeSH terms: "Antipsychotic Agents" AND "Alzheimer Disease" OR "Dementia" AND "Mortality" and selected articles published in the last 5 years.Results: Antipsychotics are widely used in the pharmacological treatment of agitation and aggression in elderly patients with AD, but their benefit is limited. Serious adverse events associated with antipsychotics include increased risk of death. The risk of mortality is associated with both typical and atypical antipsychotics. Antipsychotic polypharmacy is associated with a higher mortality risk than monotherapy and should be avoided. The mortality risk increases after the first few days of treatment, gradually reducing but continues to increase after two years of treatment. Haloperidol is associated with a higher mortality risk and quetiapine with a lower risk than risperidone.Conclusions: If the use of antipsychotics is considered necessary, the lowest effective dose should be chosen and the duration should be limited because the mortality risk remains high with long-term use. The risk / benefit should be considered when choosing the antipsychotic. Further studies on the efficacy and risk of adverse events with antipsychotics are needed for a better choice of treatment and adequate monitoring with risk reduction.

ObjectivesTo determine the long-term safety and efficacy of allopurinol dose escalation (DE) to achieve target serum urate (SU) in gout.MethodsPeople, including those with chronic kidney disease, who completed the first 12 months of a randomised controlled trial continued into a 12-month extension study. Participants randomised to continue current dose for the first 12 months began allopurinol DE at month 12 if SU was ≥6 mg/dL (control/DE). Immediate DE participants who achieved target SU maintained allopurinol dose (DE/DE). The primary endpoints were reduction in SU and adverse events (AEs) at month 24.ResultsThe mean (SE) change in SU from month 12 to 24 was −1.1 (0.2) mg/dL in control/DE and 0.1 (0.2) mg/dL in DE/DE group (p<0.001). There was a significant reduction in the percentage of individuals having a gout flare in the month prior to months 12 and 24 compared with baseline in both groups and in mean tophus size over 24 months, but no difference between randomised groups. There were similar numbers of AEs and serious adverse events between groups.ConclusionsThe majority of people with gout tolerate higher than creatinine clearance-based allopurinol dose and achieve and maintain target SU. Slow allopurinol DE may be appropriate in clinical practice even in those with kidney impairment.Trial registration numberACTRN12611000845932

AbstractHuman immunodeficiency virus (HIV)-1-specific broadly neutralizing monoclonal antibodies are currently under development to treat and prevent HIV-1 infection. We performed a single-center, randomized, double-blind, dose-escalation, placebo-controlled trial of a single administration of the HIV-1 V3-glycan-specific antibody PGT121 at 3, 10 and 30 mg kg–1 in HIV-uninfected adults and HIV-infected adults on antiretroviral therapy (ART), as well as a multicenter, open-label trial of one infusion of PGT121 at 30 mg kg–1 in viremic HIV-infected adults not on ART (no. NCT02960581). The primary endpoints were safety and tolerability, pharmacokinetics (PK) and antiviral activity in viremic HIV-infected adults not on ART. The secondary endpoints were changes in anti-PGT121 antibody titers and CD4+ T-cell count, and development of HIV-1 sequence variations associated with PGT121 resistance. Among 48 participants enrolled, no treatment-related serious adverse events, potential immune-mediated diseases or Grade 3 or higher adverse events were reported. The most common reactions among PGT121 recipients were intravenous/injection site tenderness, pain and headache. Absolute and relative CD4+ T-cell counts did not change following PGT121 infusion in HIV-infected participants. Neutralizing anti-drug antibodies were not elicited. PGT121 reduced plasma HIV RNA levels by a median of 1.77 log in viremic participants, with a viral load nadir at a median of 8.5 days. Two individuals with low baseline viral loads experienced ART-free viral suppression for ≥168 days following antibody infusion, and rebound viruses in these individuals demonstrated full or partial PGT121 sensitivity. The trial met the prespecified endpoints. These data suggest that further investigation of the potential of antibody-based therapeutic strategies for long-term suppression of HIV is warranted, including in individuals off ART and with low viral load.

Abstract Introduction Frailty is common in clinical practice, but trials rarely report on participant frailty. Consequently, clinicians and guideline-developers assume frailty is largely absent from trials and have questioned the relevance of trial findings to frail people. Therefore, we examined frailty in phase 3/4 industry-sponsored clinical trials of pharmacological interventions for three exemplar conditions: type 2 diabetes mellitus (T2DM), rheumatoid arthritis (RA), and chronic obstructive pulmonary disease (COPD). Methods We constructed a 40-item frailty index (FI) in 19 clinical trials (7 T2DM, 8 RA, 4 COPD, mean age 42–65 years) using individual-level participant data. Participants with a FI &gt;0.24 were considered “frail”. Baseline disease severity was assessed using HbA1c for T2DM, Disease Activity Score-28 (DAS28) for RA, and % predicted FEV1 for COPD. Using generalised gamma regression, we modelled FI on age, sex and disease severity. In negative binomial regression we modelled serious adverse event rates on FI, and combined results for each index condition in a random-effects meta-analysis. Results All trials included frail participants: prevalence 7–21% in T2DM trials, 33–73% in RA trials, and 15–22% in COPD trials. Increased disease severity and female sex were associated with higher FI in all trials. Frailty was associated with age in T2DM and RA trials, but not in COPD. Across all trials, and after adjusting for age, sex, and disease severity, higher FI predicted increased risk of serious adverse events; the pooled incidence rate ratios (per 0.1-point increase in FI scale) were 1.46 (95% CI 1.21–1.75), 1.45 (1.13–1.87) and 1.99 (1.43–2.76) for T2DM, RA and COPD, respectively. Conclusion Frailty is identifiable and prevalent among middle aged and older participants in phase 3/4 drug trials and has clinically important safety implications. Trial data may be harnessed to better understand chronic disease management in people living with frailty.

Objective: To evaluate the effectiveness of guanfacine extended-release (GXR) versus placebo as adjunct therapy to usual care stimulant therapy in improving executive function in children aged 6 to 12 years diagnosed with ADHD. Method: In this single center, double-blind placebo-controlled crossover trial, subjects continued to take their psychostimulant and were randomly assigned at baseline to receive active treatment or placebo first. Efficacy measures included Behavioural Rating Inventory of Executive Function (BRIEF-P), ADHD Rating Scale IV (ADHD-RS IV), and Clinical Global Impressions of Severity of Illness (CGI-S) and Improvement (CGI-I) scales. Safety measures included adverse events and vital signs. Results: Significant benefits of GXR plus psychostimulant were observed on BRIEF-P ( p value = .0392), ADHD-RS-IV ( p < .0001), CGI-S ( p = .0007), and CGI-I ( p = .003). There were no serious adverse events and no new safety signals. Conclusion: Use of GXR as adjunctive therapy to stimulant therapy significantly improves executive function in children with ADHD.

Persistent tachycardia in patients with septic shock predicts poor outcome. This study sought to investigate the effect of the cardiac pacemaker current inhibitor ivabradine on heart rate and cardio-circulatory function in patients with septic shock. After informed consent, 60 patients with septic shock and persistent tachycardia (heart rate >95 /minute) were prospectively randomly assigned to receive either standard therapy for septic shock (group S) or standard therapy along with enteral ivabradine (group I) for the initial 96 hours after enrolment. Primary outcome was the difference in heart rate between the two groups during the first 96 hours. Secondary outcomes included the effect of ivabradine on haemodynamic, oxygenation, myocardial function and organ function parameters, incidence of adverse events and 30-day overall survival. Heart rate was lower in group I compared to group S (median difference in area under the curve –25.6 (95% confidence intervals –31.4 to –15.9) /minute; P <0.001). Vasopressor requirements, blood lactate levels, Sequential Organ Failure Assessment scores and E/e′ ratio were lower in group I compared to group S. Stroke volume index and ejection fraction were higher in group I while cardiac index and oxygen delivery parameters were maintained similar to group S. There was no difference in 30-day mortality or in the incidence of serious adverse events. Enteral ivabradine is effective in reducing heart rate, and improving haemodynamic parameters and cardiac function in patients with septic shock and persistent tachycardia, without increasing the incidence of adverse events.
