- IMPORTANCE: p38 Mitogen-activated protein kinase (MAPK)-stimulated inflammation is implicated in atherogenesis, plaque destabilization, and maladaptive processes in myocardial infarction (MI). Pilot data in a phase 2 trial in non-ST elevation MI indicated that the p38 MAPK inhibitor losmapimod attenuates inflammation and may improve outcomes. OBJECTIVE: To evaluate the efficacy and safety of losmapimod on cardiovascular outcomes in patients hospitalized with an acute myocardial infarction. DESIGN, SETTING, AND PATIENTS: LATITUDE-TIMI 60, a randomized, placebo-controlled, double-blind, parallel-group trial conducted at 322 sites in 34 countries from June 3, 2014, until December 8, 2015. Part A consisted of a leading cohort (n = 3503) to provide an initial assessment of safety and exploratory efficacy before considering progression to part B (approximately 22,000 patients). Patients were considered potentially eligible for enrollment if they had been hospitalized with an acute MI and had at least 1 additional predictor of cardiovascular risk. INTERVENTIONS: Patients were randomized to either twice-daily losmapimod (7.5 mg; n = 1738) or matching placebo (n = 1765) on a background of guideline-recommended therapy. Patients were treated for 12 weeks and followed up for an additional 12 weeks. MAIN OUTCOMES AND MEASURES: The primary end point was the composite of cardiovascular death, MI, or severe recurrent ischemia requiring urgent coronary revascularization with the principal analysis specified at week 12. RESULTS: In part A, among the 3503 patients randomized (median age, 66 years; 1036 [29.6%] were women), 99.1% had complete ascertainment for the primary outcome. The primary end point occurred by 12 weeks in 123 patients treated with placebo (7.0%) and 139 patients treated with losmapimod (8.1%; hazard ratio, 1.16; 95% CI, 0.91-1.47; P = .24). The on-treatment rates of serious adverse events were 16.0% with losmapimod and 14.2% with placebo. CONCLUSIONS AND RELEVANCE: Among patients with acute MI, use of losmapimod compared with placebo did not reduce the risk of major ischemic cardiovascular events. The results of this exploratory efficacy study did not justify proceeding to a larger efficacy trial in the existing patient population. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT02145468.

- Despite the availability of a number of different classes of therapeutic agents with proven efficacy in heart failure, the clinical course of heart failure patients is characterized by a reduction in life expectancy, a progressive decline in health-related quality of life and functional status, as well as a high risk of hospitalization. New approaches are needed to address the unmet medical needs of this patient population. The European Medicines Agency (EMA) is undertaking a revision of its Guideline on Clinical Investigation of Medicinal Products for the Treatment of Chronic Heart Failure. The draft version of the Guideline was released for public consultation in January 2016. The Cardiovascular Round Table of the European Society of Cardiology (ESC), in partnership with the Heart Failure Association of the ESC, convened a dedicated two-day workshop to discuss three main topic areas of major interest in the field and addressed in this draft EMA guideline: (i) assessment of efficacy (i.e. endpoint selection and statistical analysis); (ii) clinical trial design (i.e. issues pertaining to patient population, optimal medical therapy, run-in period); and (iii) research approaches for testing novel therapeutic principles (i.e. cell therapy). This paper summarizes the key outputs from the workshop, reviews areas of expert consensus, and identifies gaps that require further research or discussion. Collaboration between regulators, industry, clinical trialists, cardiologists, health technology assessment bodies, payers, and patient organizations is critical to address the ongoing challenge of heart failure and to ensure the development and market access of new therapeutics in a scientifically robust, practical and safe way.

- AimsIn heart failure, non-adherence increases events; in turn, the effect of hospitalization on adherence is incompletely understood. We explored the relationship of non-adherence to outcomes, hospitalizations with non-adherence, and the influence of non-adherence on treatment effects of heart rate lowering with ivabradine. Methods and resultsIn the randomized, controlled Systolic Heart failure treatment with the If-inhibitor ivabradine Trial (SHIFT), we studied the effect of non-adherence (n = 1287) compared with adherence (n=5204) on cardiovascular outcomes. After adjustment, non-adherence was associated with the primary composite endpoint of cardiovascular death and heart failure hospitalization (hazard ratio 3.47, 95% confidence interval 2.91-4.13, P < 0.0001). No interaction with the treatment groups of placebo or ivabradine (P for interaction 0.54) occurred. Similar results for cardiovascular death and heart failure hospitalization, as well as for cardiovascular hospitalization, heart failure death, and total death were observed. The effect of ivabradine was maintained in patients being adherent or becoming non-adherent during the trial (P for interaction=0.54). Patients with a previous hospitalization were more likely to become non-adherent thereafter. ConclusionsNon-adherence identifies a group at particularly high cardiovascular event risk independent of treatment allocation. Non-adherent patients in the ivabradine group maintain a treatment benefit. Patients with previous hospitalizations are more likely to become non-adherent and represent a group of particularly high-risk patients in whom special attention to stimulate adherence may be valuable.

- Aims We compared clinical outcomes in patients with AF with and without diabetes in the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation trial. Methods and results The main efficacy endpoints were SSE and mortality; safety endpoints were major and major/clinically relevant non-major bleeding. A total of 4547/18 201 (24.9%) patients had diabetes who were younger (69 vs. 70 years), more had coronary artery disease (39 vs. 31%), and higher mean CHADS(2) (2.9 vs. 1.9) and HAS-BLEDscores (1.9 vs. 1.7) (all P, 0.0001) than patients without diabetes. Patients with diabetes receiving apixaban had lower rates of SSE [hazard ratio (HR) 0.75, 95% confidence interval (CI) 0.53-1.05), all-cause mortality (HR 0.83, 95% CI 0.67-1.02), cardiovascular mortality (HR 0.89, 95% CI 0.66-1.20), intra-cranial haemorrhage (HR 0.49, 95% CI 0.25-0.95), and a similar rate of myocardial infarction (HR 1.02, 95% CI 0.62-1.67) compared with warfarin. For major bleeding, a quantitative interaction was seen (P-interaction = 0.003) with a greater reduction in major bleeding in patients without diabetes even after multivariable adjustment. Other measures of bleeding showed a consistent reduction with apixaban compared with warfarin without a significant interaction based on diabetes status. Conclusion Apixaban has similar benefits on reducing stroke, decreasing mortality, and causing less intra-cranial bleeding than warfarin in patients with and without diabetes.
