Abstract Objective We analyzed the long‐term safety and effectiveness of fenfluramine (FFA) in patients with Dravet syndrome (DS) in an open‐label extension (OLE) study after participating in randomized controlled trials (RCTs) or commencing FFA de novo as adults. Methods Patients with DS who participated in one of three RCTs or were 19 to 35 years of age and started FFA de novo were included. Key endpoints were: incidence of treatment‐emergent adverse events (TEAEs) in the safety population, and median percentage change in monthly convulsive seizure frequency (MCSF) from the RCT baseline to end of study (EOS) in the modified intent‐to‐treat (mITT) population. Post hoc analyses compared effectiveness in patients on concomitant stiripentol (STP) vs those not taking STP, and assessed safety (TEAEs) and effectiveness (Clinical Global Impression‐Improvement [CGI‐I] scale ratings) in patients enrolled as adults. Results A total of 374 patients, including 45 adults, received ≥1 FFA dose. Median FFA exposure was 824 days (range, 7–1280). TEAEs occurring in ≥10% of patients were pyrexia, nasopharyngitis, decreased appetite, seizure, decreased blood glucose, diarrhea, abnormal echocardiography (only physiologic regurgitation), upper respiratory tract infection, influenza, vomiting, and ear infection; no valvular heart disease or pulmonary arterial hypertension was observed over the OLE. In the mITT population ( n = 324), median percentage change in MCSF from baseline to EOS was −66.8% ( p < .001). The post hoc analyses of MCSF change from baseline to EOS in patients on concomitant STP ( n = 75) was −36.2% vs −71.6% in those not on concomitant STP ( n = 234) ( p < .0001). In adult patients, 29 of 41 (70.7%) and 29 of 42 patients (69.1%) demonstrated clinically meaningful improvement on CGI‐I at last visit as rated by caregivers and investigators, respectively. Significance Our OLE study of FFA in patients with DS confirmed previous positive findings and extended the exposure up to 3.5 years. No new or unexpected safety signals were observed and FFA demonstrated sustained and clinically meaningful reduction in MCSF.

Importance Excess body fat plays a pivotal role in the pathogenesis of heart failure with preserved ejection fraction (HFpEF). HU6 is a novel, controlled metabolic accelerator that enhances mitochondrial uncoupling resulting in increased metabolism and fat-specific weight loss. Objective To assess efficacy and safety of HU6 in reducing body weight, improving peak volume of oxygen consumption (VO 2 ) and body composition among patients with obesity-related HFpEF. Design, Setting, and Participants The Exploratory Phase 2A, Double-Blind, Placebo-Controlled Dose Escalation Study of Safety, Tolerability, Pharmacodynamics, and Pharmacokinetics of HU6 for Subjects With Obese HFpEF (HuMAIN-HFpEF) trial was a multicenter, dose-escalation randomized clinical trial among patients with chronic stable HFpEF and obesity. Data were analyzed from July to October 2024. Intervention HU6 treatment for 19 weeks, starting at 150 mg per day and potentially up titrated to 450 mg per day based on safety and tolerability vs placebo. Main Outcomes and Measures The primary end point was change in body weight. Results Of 66 participants randomized (mean [SD] age, 64.5 [12] years; 38 female [58%]; mean [SD] weight, 110.9 [22.4] kg), 56 completed the trial. HU6 (vs placebo) significantly decreased weight (between-group difference, −2.86 kg; 95% CI, −4.68 to −1.04 kg; P = .003), total fat mass (between-group difference, −2.96 kg; 95% CI, −4.50 to −1.42 kg; P &amp;lt; .001), and percentage visceral fat (between-group difference,−1.3%; 95% CI, −2.1 to −0.5%; P = .003), with no significant loss of muscle mass. There were no statistically significant changes in peak VO 2 , 6-minute walk distance, Kansas City Cardiomyopathy Questionnaire score, high-sensitivity C-reactive protein level, N-terminal pro–brain natriuretic peptide level, or diastolic function. Serious adverse events were noted in 5 participants (4 in the HU6 group; 1 in the placebo group), including 1 death, all judged unrelated to treatment. Conclusions and Relevance Among patients with obesity-related HFpEF, treatment with HU6 for 19 weeks led to modest but statistically significant weight loss without significant changes in peak VO 2 . Larger trials of longer duration are warranted to determine whether longer-term administration of HU6 can improve exercise function, quality of life, and cardiovascular outcomes in this increasingly common disorder.

Précis: Patients with clinically uncontrolled open angle glaucoma submitted to isolated gonioscopy-assisted transluminal trabeculotomy or combined with phacoemulsification not only achieved low mean IOPs, but also demonstrated stable IOP patterns during a 24-month follow-up. Purpose: To assess the impact of gonioscopy-assisted transluminal trabeculotomy (GATT) on long-term intraocular pressure (IOP) variation. Patients and Methods: An unicentric retrospective study including 169 consecutive patients who had undergone standalone GATT or combined with phacoemulsification (PHACOGATT) due to clinically uncontrolled open angle glaucoma, with at least 12 months of follow-up was conducted. Long-term mean IOP, long-term IOP peak, long-term IOP fluctuation, coefficient of variation, mean-positive IOP variation, sustained clinically significant positive IOP variation, and number of follow-up visits with IOP ≥15 mm Hg were investigated. Results: One hundred sixty-nine eyes from 169 patients were included (GATT group=101 patients; PHACOGATT group=68 patients). Mean long term IOP (12.0±1.8 vs. 11.2±2.0 mm Hg), mean long-term IOP peak (12.9±2.6 vs. 11.8±3.5 mm Hg), and mean coefficient of variation (0.07±0.08 vs. 0.05±0.09) were lower in the PHACOGATT group, while mean IOP fluctuation (1.0±3.7 vs. 1.2±1.8 mm Hg) was lower in the GATT group. In addition, the overall mean-positive IOP variation was 0.79±1.64 mm Hg. Finally, only 6.5% of the patients presented sustained clinically significant positive IOP variation and IOP was ≥15 mm Hg in 5.9% of the follow-up visits. Conclusions: Patients with clinically uncontrolled open angle glaucoma submitted to GATT or PHACOGATT achieved low mean IOPs and demonstrated stable IOP patterns. Our results provide additional evidence supporting GATT and PHACOGATT as viable options for the treatment of medically uncontrolled glaucoma patients requiring low and stable IOPs.

AbstractThe intricate role of the autonomic nervous system (ANS) in regulating cardiac physiology has long been recognized. Aberrant function of the ANS is central to the pathophysiology of cardiovascular diseases. It stands to reason, therefore, that neuroscience‐based cardiovascular therapeutics hold great promise in the treatment of cardiovascular diseases in humans. A decade after the inaugural edition, this White Paper reviews the current state of understanding of human cardiac neuroanatomy, neurophysiology and pathophysiology in specific disease conditions, autonomic testing, risk stratification, and neuromodulatory strategies to mitigate the progression of cardiovascular diseases. image

Abstract This mini review explores the association of interstitial lung disease (ILD) with antineutrophil cystoplasmic antibodies (ANCA) and the clinical syndrome of microscopic polyangiitis (MPA). Reports on radiographic and histopathologic findings as well as genetic predispositions are reviewed. Based on this evidence a concept for the pathogenesis of the relationship of ILD, MPO-ANCA and MPA is proposed. Finally, a practical clinical management approach to patients presenting either with ILD and a positive ANCA test result, or to patients with MPA found to have pulmonary abnormalities qualifying as an ILD, is derived from the currently available literature. Treatment of these patients is based on up-to-date guidelines for the management of ILD as well as ANCA-associated vasculitis.

Abstract The session on other forms of vasculitis included a masterful review on IgG4-related disease (IgG4-RD) following which two research studies evaluating therapeutic agents and one study on histopathologic findings of IgG4-RD were presented. Peyronel F., et al. discussed the results of a prospective multicentre randomized clinical trial evaluating methotrexate for patients with retroperitoneal fibrosis. Methotrexate, in combination with a tapering regimen of glucocorticoids, was effective in inducing remission and allows use of lower cumulative prednisone doses. Hobbelink J., et al. evaluated the histopathologic scoring system from the ACR/EULAR Classification criteria for IgG4-RD. Their study found that these criteria were able to distinguish patients with confirmed and suspected IgG4-RD. Trivioli G et al. retrospectively evaluated rituximab in adult-onset IgA Vasculitis (IgAV) and crescentic IgA Nephropathy (cIgAN). Rituximab resulted in high rate of renal response in IgAV but remission rates in cIgAN remained lower with poorer renal outcomes compared with IgAV.

The NCCN Guidelines for Myelodysplastic Syndromes (MDS) provide recommendations for the evaluation, diagnosis, and comprehensive care of patients with MDS based on a review of recent clinical evidence that has led to important advances in treatment or has yielded new information on biologic factors that may have prognostic significance in MDS. The multidisciplinary panel of MDS experts is convened at least on an annual basis. During the annual meeting, the panel evaluates new and emerging data to inform their recommendations. These NCCN Guidelines Insights review the recent updates, including treatment recommendations both for lower-risk and higher-risk MDS, preference stratification of therapeutic agents, and emerging data on novel therapeutics.
