RESUMO

AIMS: People with type 2 diabetes (T2D) face high risks of heart failure (HF) hospitalizations that are often recurrent, especially as kidney function declines. We examined the effects of canagliflozin on total HF events by baseline kidney function in patients with T2D at high cardiovascular risk and/or with chronic kidney disease. METHODS AND RESULTS: Leveraging pooled participant-level data from the CANVAS programme (n = 10 142) and CREDENCE trial (n = 4401), first and total HF hospitalizations were examined. Cox proportional hazards models were built for the time to first HF hospitalization, and proportional means models based on cumulative mean functions were used for recurrent HF hospitalizations. Treatment effects were evaluated overall as well as within baseline estimated glomerular filtration rate (eGFR) strata (<45, 45-60, and >60 ml/min/1.73 m2). HF hospitalizations were independently and blindly adjudicated. Among 14 540 participants with available baseline eGFR values, 672 HF hospitalizations occurred over a median follow-up of 2.5 years. Among participants who experienced a HF hospitalization, 357 had a single event (201 in placebo-treated patients and 156 in canagliflozin-treated patients), 77 had 2 events, and 39 had >2 events. Canagliflozin reduced risk of first HF hospitalization (hazard ratio 0.58, 95% confidence interval [CI] 0.48-0.70) consistently across baseline eGFR strata (pinteraction = 0.84). Canagliflozin reduced total HF hospitalizations overall (mean event ratio 0.63, 95% CI 0.54-0.73) and across eGFR subgroups (pinteraction = 0.51). Canagliflozin also reduced cardiovascular death and total HF hospitalizations (mean event ratio 0.72, 95% CI 0.65-0.80) and across eGFR subgroups (pinteraction = 0.82). The absolute risk reductions were numerically larger, and numbers needed to treat were smaller when evaluating total events versus first events alone. These observed HF benefits were highly consistent across the range of eGFR, with larger absolute benefits in participants who had worse kidney function at baseline. CONCLUSIONS: In individuals with T2D at high cardiovascular risk and/or with chronic kidney disease, canagliflozin reduced the total burden of HF hospitalizations, with consistent benefits observed across the kidney function spectrum.

RESUMO

BACKGROUND: People with type 2 diabetes mellitus (T2DM) have elevated cardiovascular (CV) risk, including for hospitalization for heart failure (HHF). Canagliflozin reduced CV and kidney events in patients with T2DM and high CV risk or nephropathy in the CANVAS (CANagliflozin cardioVascular Assessment Study) Program and the CREDENCE (Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation) trial. OBJECTIVES: The aim of this study was to assess the effects of canagliflozin on CV outcomes according to baseline estimated glomerular filtration rate (eGFR) and urine albumin:creatinine ratio (UACR) in pooled patient-level data from the CANVAS Program and CREDENCE trial. METHODS: Canagliflozin effects on CV death or HHF were assessed by baseline eGFR (<45, 45-60, and >60 mL/min/1.73 m2) and UACR (<30, 30-300, and >300 mg/g). HRs and 95% CIs were estimated by using Cox regression models overall and according to subgroups. RESULTS: A total of 14,543 participants from the CANVAS Program (N = 10,142) and the CREDENCE (N = 4,401) trial were included, with a mean age of 63 years, 35% female, 75% White, 13.2% with baseline eGFR <45 mL/min/1.73 m2, and 31.9% with UACR >300 mg/g. Rates of CV death or HHF increased as eGFR declined and/or UACR increased. Canagliflozin significantly reduced CV death or HHF compared with placebo (19.4 vs 28.0 events per 1,000 patient-years; HR: 0.70; 95% CI: 0.62-0.79), with consistent results across eGFR and UACR categories (all P interaction >0.40). CONCLUSIONS: Risk of CV death or HHF was higher in those with lower baseline eGFR and/or higher UACR. Canagliflozin consistently reduced CV death or HHF in participants with T2DM and high CV risk or nephropathy regardless of baseline renal function or level of albuminuria.

RESUMO

Objective: To describe the tolerability of esketamine nasal spray based on the adverse event profile observed during treatment sessions occurring early and later over the course of treatment.Methods: In 2 long-term, phase 3 studies (NCT02493868, October 1, 2015-February 16, 2018; NCT02497287, September 30, 2015-October 28, 2017), patients with treatment-resistant major depressive disorder (per DSM-5) and nonresponse to ≥ 2 oral antidepressants received esketamine nasal spray (56 or 84 mg) twice weekly during a 4-week induction phase, weekly for weeks 5-8, and weekly or every 2 weeks thereafter as maintenance treatment, in conjunction with a new oral antidepressant. A post hoc analysis using descriptive statistics evaluated occurrence (incidence, frequency, severity) and recurrence (incidence and severity) of events of specific interest.Results: In patients treated with esketamine nasal spray plus a newly initiated oral antidepressant (n = 928), spontaneously reported adverse events of dizziness, nausea, sedation, vertigo, and increased blood pressure were more likely to recur after the first week of treatment if they occurred more frequently (twice > once > none) during the first week. The same pattern was observed when these events were assessed by structured instruments. Incidences of dizziness, dissociation, increased blood pressure, nausea, vertigo, and sedation were highest in week 1 of treatment (20.6%, 16.7%, 4.3%, 14.0%, 12.1%, and 3.8%, respectively) and decreased thereafter. Initial occurrences and subsequent recurrences of events were mostly mild or moderate in severity.Conclusions: Adverse events during treatment with esketamine nasal spray plus an oral antidepressant generally become less frequent with ongoing treatment, and the majority are mild or moderate in severity.Trial Registration: ClinicalTrials.gov identifiers: NCT02493868; NCT02497287.

RESUMO

OBJECTIVE: Derive and confirm factor structure of the Montgomery-Åsberg Depression Rating Scale (MADRS) in patients with treatment-resistant depression (TRD) and evaluate how the factors evident at baseline change over 4 weeks of esketamine treatment. METHODS: Two similarly-designed, short-term TRANSFORM trials randomized adults to esketamine or matching placebo nasal spray, each with a newly-initiated oral antidepressant, for 4 weeks (TRANSFORM-1: N = 342 patients; TRANSFORM-2: N = 223 patients). The factor structure of MADRS item scores at baseline was determined by exploratory factor analysis in TRANSFORM-2 and corroborated by confirmatory factor analysis in TRANSFORM-1. Change in MADRS factor scores from baseline (day 1) to the end of the 28-day double-blind treatment phase of TRANSFORM-2 was analyzed using a mixed-effects model for repeated measures (MMRM). RESULTS: Three factors were identified based on analysis of MADRS items: Factor 1 labeled affective and anhedonic symptoms (apparent sadness, reported sadness, lassitude, inability to feel), Factor 2 labeled anxiety and vegetative symptoms (inner tension, reduced sleep, reduced appetite, concentration difficulties), and Factor 3 labeled hopelessness (pessimistic thoughts, suicidal thoughts). The three-factor structure observed in TRANSFORM-2 was verified in TRANSFORM-1. Treatment benefit at 24 h with esketamine versus placebo was observed on all 3 factors and continued throughout the 4-week double-blind treatment period. CONCLUSIONS: A three-factor structure for MADRS appears to generalize to TRD. All three factors improved over 4 weeks of treatment with esketamine nasal spray.

RESUMO

BACKGROUND: Schizophrenia is a lifelong illness that requires long-term treatment and caregiving. Family psychoeducation (FP) has been shown to lessen caregiver burden, improve caregiver functioning, and improve outcomes in patients. However, the impact of FP delivered specifically to caregivers on patient outcomes has not been well explored, particularly for early schizophrenia. Furthermore, there is a lack of research examining the benefits of telehealth-based psychoeducation for caregivers on either patient or caregiver outcomes. OBJECTIVE: The Family Intervention in Recent-Onset Schizophrenia Treatment (FIRST) study is a randomized controlled trial of patients with schizophrenia spectrum disorders and their caregivers, which is designed to evaluate the effect of telehealth-based, caregiver-focused, study-provided psychoeducation versus usual care (UC) on patient treatment failure (TF). The impact of study-provided psychoeducation on caregiver burden is also investigated. METHODS: Eligible patients and their designated caregivers were randomly assigned to either the study-provided psychoeducation (≤16 sessions of telehealth-based psychoeducation over 6 months) or UC group, stratified by antipsychotic treatment (paliperidone palmitate or oral antipsychotic). The major TF events (ie, psychiatric hospitalization or intervention, arrest or incarceration, and suicide attempts) were assessed at 3, 6, and 12 months after baseline. A proportional means model using mean cumulative function was used to assess between-group differences in the mean cumulative number of TF events over 12 months. Caregiver burden was assessed using the Involvement Evaluation Questionnaire and 12-item Short Form Health Survey. RESULTS: A total of 148 pairs of participants were enrolled in the study, of whom 96 (64.9%) patients and 94 (63.5%) caregivers completed the 12-month follow-up. The mean number of sessions in the study-provided psychoeducation group was 7.7 (SD 5.9). No differences were observed between the study-provided psychoeducation and UC groups in patient outcomes (rates of TF: 70% vs 67%; P=.90) or measures of caregiver burden (assessment of caregiver distress and physical and mental health). However, post hoc analyses revealed lower relapse rates in patients who received paliperidone palmitate than in those who received oral antipsychotics at all time points. Although the FIRST study did not meet the primary end point, several key lessons were identified to inform future caregiver-focused, telehealth-based FP interventions. Lack of study-provided psychoeducation, focus on caregiver-only intervention, difficulties with enrollment, and caregiver-treatment team coordination may have affected the outcomes of the FIRST study. CONCLUSIONS: Key insights from the FIRST study suggest the potential importance of supporting sufficient caregiver engagement; communication between clinicians, patients, and family members regarding treatment plans; and solidifying the relationship between clinicians providing psychoeducation to the caregiver and patient treatment team.

RESUMO

AIM: To assess the risk of major adverse cardiovascular events (MACE) of canagliflozin in Hispanic patients with type 2 diabetes (T2D) and high cardiovascular risk or nephropathy with varying levels of kidney function. MATERIALS AND METHODS: This post hoc analysis included integrated, pooled data from the CANVAS Program and CREDENCE trial. The effects of canagliflozin versus placebo on major adverse cardiovascular events (MACE; i.e. cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke) were assessed in subgroups by baseline estimated glomerular filtration rate (eGFR; <45, 45-60, and >60 mL/min/1.73 m2 ) overall and in the Hispanic cohort. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox regression models, with subgroup by treatment interaction terms added to test for heterogeneity. RESULTS: A total of 14 543 participants were included; 3029 (20.8%) self-identified as Hispanic. In the overall population, canagliflozin reduced the risk of MACE compared with placebo (HR, 0.83; 95% CI, 0.75, 0.92), with no heterogeneity observed across eGFR subgroups (interaction P = .22). In the Hispanic cohort, canagliflozin also reduced the risk of MACE (HR, 0.71; 95% CI, 0.55, 0.92), with no heterogeneity by baseline eGFR (interaction P = .25), including among the Hispanic participants at highest risk with a baseline eGFR of less than 45 mL/min/1.73 m2 . CONCLUSION: Canagliflozin reduced the risk of MACE overall, and among Hispanic participants with T2D and high cardiovascular risk or nephropathy in the CANVAS Program and CREDENCE trial, without heterogeneity by baseline eGFR.

RESUMO

OBJECTIVE: To examine the efficacy and safety of paliperidone palmitate once-monthly (PP1M) versus oral antipsychotics (OAPs) in Black/African American patients with schizophrenia and a history of criminal justice system involvement. METHODS: This was a post hoc analysis of a 15-month prospective, randomized, open-label, parallel-group, multicenter US study conducted from May 2010 to December 2013 that examined a subpopulation of Black/African American patients with schizophrenia (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria). The primary objective was to compare time to first treatment failure in patients treated with PP1M versus OAPs. Secondary objectives were to compare time to first institutionalization (psychiatric hospitalization or arrest/incarceration) and mean number of treatment failure events and institutionalizations over 15 months in PP1M-treated and OAP-treated patients. RESULTS: The intention-to-treat population included 275 Black/African American patients (PP1M, n = 145; OAPs, n = 130). Median time to first treatment failure was not reached for PP1M-treated patients and was 270 days for OAP-treated patients; hazard ratio (HR) was 1.39 (95% CI, 0.97-1.99; P = .075). Median time to first institutionalization was not reached for PP1M-treated patients and was 304 days for OAP-treated patients; HR was 1.49 (95% CI, 1.01-2.19; P = .043). Mean numbers of treatment failure events and institutionalizations were lower with PP1M than OAPs. The safety profile of PP1M was consistent with that of previous PP1M studies. CONCLUSIONS: In a Black/African American subpopulation of patients with schizophrenia and prior criminal justice system involvement, PP1M reduced the number of treatment failures, thereby reducing the number of psychiatric hospitalizations and/or arrests/incarcerations compared with daily OAPs.

RESUMO

Esketamine nasal spray (ESK) is indicated, in conjunction with an oral antidepressant (OAD), for the management of treatment-resistant depression (TRD) in adults. Select US-based patients from an open-label, long-term extension safety study of ESK (NCT02782104) participated in this study through semi-structured interviews. The study evaluated patient-reported early health changes related to emotional health, daily functioning, and social functioning in adults with TRD treated with ESK plus OAD. Eligible patients were responders to ESK who had begun initial ESK treatment ≤30 months before enrollment and were currently receiving ESK plus OAD. Results from 23 patients (9 men, 14 women; mean age, 46 years) were analyzed. Patients described the degree to which ESK treatment changed the effects of depression on aspects of health as either being much improved or improved (91.8%, 156/170). Key characteristics noted regarding treatment with ESK plus OAD included degree of effectiveness (n = 11), rapid onset of action (n = 7), and side-effect profile (n = 5). All patients reported being either satisfied (52%) or very satisfied (48%) with ESK plus OAD treatment. Adverse events were consistent with the known safety profile of ESK. Study insights may help prepare patients with TRD and their clinicians to anticipate potential health changes experienced with ESK.

RESUMO

BACKGROUND: Negative symptoms in schizophrenia are associated with impairments in social and cognitive functioning leading to substantial long-term disability. Available antipsychotic treatments have demonstrated only modest benefit in the improvement of negative symptoms. OBJECTIVE: To compare improvements in negative symptoms among patients treated with paliperidone palmitate 3-month (PP3M) or paliperidone palmitate 1-month (PP1M) long-acting injectable (LAI) formulations. METHODS: Data from a randomized double-blind (DB), phase-3, non-inferiority study in patients with schizophrenia were analyzed. Following screening, patients entered a 17-week open-label (OL) phase to receive flexibly dosed PP1M followed by a 48-week DB phase where patients were randomized (1:1) to receive either PP1M or PP3M. Positive and Negative Syndrome Scale (PANSS) total scores with emphasis on 7-item negative subscale scores for PP1M vs PP3M were assessed. RESULTS: Of 1429 patients enrolled, 1016 were randomized to receive PP3M (n=504) or PP1M (n=512). At baseline, mean (SD) PANSS negative subscale was 23.2 (4.60) and negative symptom factor score was 22.3 (4.87), indicating moderate-to-severe negative symptoms. Negative subscale and symptoms factor scores showed continuous improvements throughout OL (15.9 [4.99]) and DB (14.9 [4.81]) phases. Mean (SD) changes from DB baseline in the PANSS negative subscale score were comparable between PP1M (-1.4 [3.67]) and PP3M (-1.4 [3.63]) treatment groups. CONCLUSION: Treatment with PP3M or PP1M demonstrated comparable improvement in negative symptoms in patients with moderate-to-severe negative symptoms and in patients with prominent negative symptoms. Long-term treatment with PP3M demonstrated benefit, suggesting that continuous antipsychotic medication treatment for >1 year is needed to achieve greater benefit for negative symptoms.

RESUMO

Disease severity varies widely in patients with severe sepsis. Eritoran tetrasodium (E5564), a TLR4 antagonist, blocks the binding of endotoxin and is being evaluated as a novel therapy for severe sepsis. This analysis aimed to assess the efficacy of eritoran based on severity of illness and similar effects in other recent sepsis trials. Prospective covariates from a randomized, double-blind, placebo-controlled, phase 2 trial were analyzed for treatment interaction measured by 28-day mortality. Five statistical interaction methodologies were used. The modified intent-to-treat population (n = 292), all-cause 28-day mortality was as follows: placebo, 33.3% (32/96); eritoran 45 mg/105 mg, 29.6% (58/196). Logistic regression analysis identified Acute Physiology and Chronic Health Evaluation II scores, predicted-risk-of-mortality scores, IL-6, age, sex, race, and eritoran use as associated with survival. Significant treatment interactions were observed (eritoran vs. placebo) for baseline covariates: Acute Physiology and Chronic Health Evaluation II (P = 0.035), predicted-risk-of-mortality scores (P = 0.008), number of organ failures (P = 0.079), international normalized ratio (P = 0.05), and acute physiology score (P = 0.039). I analysis showed that 38% of the total eritoran treatment variance was explained by the severity-of-illness heterogeneity rather than by chance. No interactions observed with other variables. Consistent with the finding in this eritoran trial, other sepsis trials (IL-1 receptor antagonist, TNFsr-p55, antithrombin, drotrecogin alfa-activated) also demonstrated significant treatment by severity interaction. Potential survival benefits of eritoran in severe sepsis patients were associated with high severity of illness. These findings were used to design a phase 3 trial. Similar treatment by severity-of-illness interaction was found in most recent sepsis trials.

RESUMO

OBJECTIVES: Endotoxin is a potent stimulus of proinflammatory response and systemic coagulation in patients with severe sepsis. Endotoxin is a component of Gram-negative bacteria that triggers an innate immune response through Toll-like receptor 4 signaling pathways in myeloid cells. We evaluated safety and tolerability of two dose regimens of eritoran tetrasodium (E5564), a synthetic Toll-like receptor 4 antagonist, and explored whether it decreases 28-day mortality rate in subjects with severe sepsis. DESIGN: Prospective, randomized, double-blind, placebo-controlled, multicenter, ascending-dose phase II trial. SETTING: Adult intensive care units in the United States and Canada. PATIENTS: Three hundred adults within 12 hrs of recognition of severe sepsis, with Acute Physiology and Chronic Health Evaluation (APACHE) II-predicted risk of mortality between 20% and 80%. INTERVENTIONS: Intravenous eritoran tetrasodium (total dose of either 45 mg or 105 mg) or placebo administered every 12 hrs for 6 days. MEASUREMENTS AND MAIN RESULTS: Prevalence of adverse events was similar among subjects treated with 45 mg or 105 mg of eritoran tetrasodium or with placebo. For modified intent-to-treat subjects, 28-day all-cause mortality rates were 26.6% (eritoran tetrasodium 105 mg), 32.0% (eritoran tetrasodium 45 mg), and 33.3% in the placebo group. Mortality rate in the eritoran tetrasodium 105-mg group was not significantly different from placebo (p = .335). In prespecified subgroups, subjects at highest risk of mortality by APACHE II score quartile had a trend toward lower mortality rate in the eritoran tetrasodium 105-mg group (33.3% vs. 56.3% placebo group, p = .105). A trend toward a higher mortality rate was observed in subjects in the lowest APACHE II score quartile for the eritoran 105-mg group (12.0% vs. 0.0% placebo group, p = .083). CONCLUSIONS: Eritoran tetrasodium treatment appears well tolerated. The observed trend toward a lower mortality rate at the 105-mg dose, in subjects with severe sepsis and high predicted risk of mortality, should be further investigated.

RESUMO

BACKGROUND: Invasive aspergillosis is an important cause of morbidity and mortality in immunocompromised patients. Current treatments provide limited benefit. Posaconazole is an extended-spectrum triazole with in vitro and in vivo activity against Aspergillus species. METHODS: We investigated the efficacy and safety of posaconazole oral suspension (800 mg/day in divided doses) as monotherapy in an open-label, multicenter study in patients with invasive aspergillosis and other mycoses who were refractory to or intolerant of conventional antifungal therapy. Data from external control cases were collected retrospectively to provide a comparative reference group. RESULTS: Cases of aspergillosis deemed evaluable by a blinded data review committee included 107 posaconazole recipients and 86 control subjects (modified intent-to-treat population). The populations were similar and balanced with regard to prespecified demographic and disease variables. The overall success rate (i.e., the data review committee-assessed global response at the end of treatment) was 42% for posaconazole recipients and 26% for control subjects (odds ratio, 4.06; 95% confidence interval, 1.50-11.04; P=.006). The differences in response between the modified intent-to-treat treatment groups were preserved across additional, prespecified subsets, including infection site (pulmonary or disseminated), hematological malignancy, hematopoietic stem cell transplantation, baseline neutropenia, and reason for enrollment (patient was refractory to or intolerant of previous antifungal therapy). An exposure-response relationship was suggested by pharmacokinetic analyses. CONCLUSIONS: Although the study predates extensive use of echinocandins and voriconazole, these findings demonstrate that posaconazole is an alternative to salvage therapy for patients with invasive aspergillosis who are refractory to or intolerant of previous antifungal therapy.

RESUMO

BACKGROUND: Oropharyngeal candidiasis is the most common opportunistic infection among persons infected with human immunodeficiency virus (HIV). Use of some agents is hampered by lack of efficacy, emergence of resistance, adverse events, and need for intravenous administration. Posaconazole is an extended-spectrum triazole with potent in vitro activity against Candida species, including Candida albicans, Candida glabrata, and Candida krusei (including fluconazole-resistant strains). METHODS: This multicenter, randomized, evaluator-blinded study of subjects with HIV infection and oropharyngeal candidiasis compared efficacy of posaconazole with that of fluconazole. Subjects received either 200 mg of posaconazole or fluconazole oral suspension on day 1, followed by 100 mg/day for 13 days. The primary study end point--clinical success (cure or improvement) on day 14--was evaluated for 329 subjects. Durability of clinical success was evaluated on day 42. RESULTS: Three hundred fifty subjects received posaconazole (n = 178) or fluconazole (n = 172). Clinical success occurred in 155 (91.7%) of 169 posaconazole recipients and in 148 (92.5%) of 160 fluconazole recipients (95% confidence interval, -6.61% to 5.04%), indicating that posaconazole was not inferior to fluconazole. On day 14, mycological success was 68% in both arms, but by day 42, significantly more posaconazole recipients than fluconazole recipients continued to have mycological success (40.6% vs. 26.4%; P=.038). Fewer posaconazole recipients than fluconazole recipients experienced clinical relapse (31.5% vs. 38.2%). Adverse events were similar between treatment arms. CONCLUSIONS: Results demonstrate that posaconazole was as effective as fluconazole in producing a successful clinical outcome. However, posaconazole was more effective in sustaining clinical success after treatment was stopped.
