Randomization to Once-Daily Stavudine Extended Release/Lamivudine/Efavirenz Versus a More Frequent Regimen Improves Adherence While Maintaining Viral Suppression

Background: In antiretroviral (ARV) therapy, pill burden, dosing frequency, and regimen complexity adversely affect adherence. We sought to evaluate the effect of regimen simplification on maintenance of virologic suppression and treatment adherence. Method: In this 48-week, open-label, randomized study, 320 HIV-1-infected adult patients with a viral load of <50 copies/mL on a twice-daily or more frequent ARV regimen were either switched to a once-daily regimen of efavirenz, extended-release stavudine, and lamivudine (QD arm) or continued on existing therapy (BID+ arm). Medication Event Monitoring System (MEMS) caps, AIDS Clinical Trials Group (ACTG)-validated questionnaire, and pill counts were used to evaluate adherence. Treatment satisfaction and preference were also evaluated. Results: The QD arm was noninferior to the BID+ arm in the primary efficacy measure (proportion of patients who maintained virologic suppression at Week 48; QD arm, 80.0% vs. BID+ arm, 75.8%). Adherence and treatment satisfaction significantly favored the QD arm, in which 91.0% of patients preferred the simpler regimen. Overall, the majority of adverse events were mild to moderate in severity and resulted in a low rate of treatment discontinuations. Conclusions: Simplifying twice-daily or more frequent ARV therapy to a once-daily efavirenz-containing regimen in virologically suppressed HIV-1-infected patients maintains virologic suppression while improving adherence and patient satisfaction

Clinical benefit of long-term adalimumab treatment in patients with Crohn's disease following loss of response or intolerance to infliximab: 96-week efficacy data from gain/adhere trials

Background and Aims: In the 4-week GAIN clinical trial, adalimumab was efficacious in inducing remission in patients with moderate-to-severe Crohn's disease [CD] who had prior loss of response/ intolerance to infliximab. The efficacy and safety of adalimumab in these patients are reported here for up to 96 weeks or for 3 years, respectively, in the ADHERE open-label extension study. Methods: Patients who completed GAIN could enrol in ADHERE and receive open-label adalimumab 40 mg every other week. Efficacy variables included clinical response (Crohn's Disease Activity Index [CDAI] decrease from baseline ≥70/≥100 points [CR-70/CR-100]) and remission [CDAI<150], steroid discontinuation and fistula remission [absence of drainage]. Data were reported using hybrid non-responder imputation [hNRI], last observation carried forward and as-observed analysis. Subgroup analyses were performed by randomized group in GAIN and by Week 4 efficacy in GAIN. Safety was also assessed. Results: A total of 310 patients from GAIN enrolled in ADHERE. CR-70, CR-100 and remission rates at Week 96 were 39.0%, 35.5%, and 26.5% [hNRI], respectively. Of the patients with CR-70 response or remission at Week 4 of GAIN, 45.5% and 44.4% [hNRI], respectively, maintained the effect at Week 96. Steroid discontinuation and steroid-free remission rates increased from Week 12 to 96 in patients using corticosteroids at GAIN baseline. Conclusions: Long-term adalimumab maintenance therapy led to sustained clinical remission and response, and steroid discontinuation in a considerable proportion of patients with CD previously treated with infliximab. No new safety signals were observed in this patient population

Adalimumab Reduces Extraintestinal Manifestations in Patients with Crohn's Disease: A Pooled Analysis of 11 Clinical Studies.

INTRODUCTION: Extraintestinal manifestations (EIMs) in patients with Crohn's disease (CD) are common and associated with additional morbidity. This study aimed to evaluate the effect of adalimumab therapy on EIM resolution and identify potential predictors of EIM resolution in adult and pediatric patients with moderate to severe CD. METHODS: EIM data were pooled from 11 induction, maintenance, and open-label extension studies of adalimumab. Resolution of EIMs was evaluated at approximately 6 months and 1 year. Median time to initial EIM resolution and first EIM recurrence (reflecting durable resolution) of any EIM and specific categories of EIMs (arthritis/arthralgia, ocular, cutaneous) were calculated. A Cox model was used to determine predictors of initial and durable EIM resolution. RESULTS: At baseline, 54% (1137/2094) of patients receiving adalimumab and 51% (297/586) receiving placebo had EIMs. EIM resolution occurred in a significantly greater proportion of adalimumab versus placebo patients at 6 months (54% vs 31%; P < .001) and 1 year (60% vs 42%; P = .008). Median time to initial resolution of any EIM, arthritis/arthralgia, and cutaneous EIMs was significantly shorter in patients receiving adalimumab versus placebo. Durable resolution of any EIM and arthritis/arthralgia was significantly longer for patients receiving adalimumab versus placebo. Clinically meaningful predictors of EIM resolution included adalimumab treatment, male sex, and moderate (versus severe) disease activity at baseline. CONCLUSION: Adalimumab is effective for achieving initial and durable resolution of any EIM and, in particular, arthritis/arthralgia in patients with moderate to severe CD. Predictors of EIM resolution included adalimumab treatment and moderate disease severity. FUNDING: AbbVie

Treatment with adenosine diphosphate receptor inhibitors-longitudinal assessment of treatment patterns and events after acute coronary syndrome (TRANSLATE-ACS) study design: expanding the paradigm of longitudinal observational research

Background: Platelet inhibition is critical in reducing both short- and long-term atherothrombotic risks after acute myocardial infarction (MI), especially among patients managed with percutaneous coronary intervention (PCI). Currently available antiplatelet medications, including adenosine diphosphate (ADP) receptor inhibitors, have demonstrated variability in efficacy and safety in clinical trials, yet few studies have examined contemporary "real-world" approaches to platelet inhibition and associated outcomes. Methods: TRANSLATE-ACS is a prospective observational study that will track up to 17,000 MI patients managed with PCI, from the inhospital to outpatient settings for up to 12 months postdischarge to provide a comprehensive picture of current treatment patterns and outcomes in routine clinical practice. TRANSLATE-ACS exemplifies a collaborative study design that efficiently builds upon a well-established PCI registry platform, and yet, through a systematic telephone interview follow-up process, provides important longitudinal clinical and economic follow-up capacity through 15 months after initial MI hospitalization. Furthermore, TRANSLATE-ACS incorporates a hospital-level, clustered, randomized substudy to investigate the impact of point-of-care platelet inhibition testing on subsequent patient management. Finally, TRANSLATE-ACS provides feedback through quarterly reports to participating sites on their care practices benchmarked to peer performance to support and promote longitudinal quality of cardiovascular care delivery. Conclusion: TRANSLATE-ACS not only addresses important clinical and scientific questions but also includes pioneering design features that will assist in the evolution of clinical registries.
