The 11th Cardiovascular Outcome Trial (CVOT) Summit: Congress on Cardiovascular, Kidney, and Metabolic Outcomes was held virtually on November 20-21, 2025. The Summit provided a multidisciplinary forum to review and discuss recent outcome trials investigating emerging pharmacological therapies targeting diseases of the cardiovascular-kidney-metabolic (CKM) continuum. This report highlights the unique developments of 2025 discussed during the Summit, including the first head-to-head CVOT (SURPASS-CVOT), the growing evidence base for combination therapies across the disease spectrum, new insights into the inflammatory component of the CKM syndrome, and relevant policy developments. The first part of this report summarizes pioneering clinical trials addressing combination therapy with finerenone and empagliflozin (CONFIDENCE), the oral glucagon-like peptide-1 (GLP-1) receptor agonists orforglipron (ATTAIN-1), and the aldosterone synthase inhibitor (ASI) baxdrostat (BaxHTN). The second part presents recent guideline and policy developments discussed by experts in endocrinology, diabetology, cardiology, nephrology, hepatology, and general practice. In addition, advances in medical technology, particularly in continuous glucose and ketone monitoring, are highlighted, as well as emerging therapies for diseases of the CKM continuum. These include pharmacological agents for a broad spectrum of metabolic disorders such as metabolic liver disease and type 1 Diabetes (T1D) alongside emphasis on the importance of early detection and innovative treatment strategies. The 12th Cardiovascular Outcome Trial Summit will be held virtually on 19-20 November 2026 (http://www.cvot.org).
Sex-determining region Y-box 2 (SOX2), a well-known stemness biomarker, is highly expressed in a variety of cancers, including human highly invasive bladder cancer (BC). However, the role of SOX2 may vary in different kinds of malignancy. In the present study, we discovered that ChlA-F, a novel conformation derivative of isolate Cheliensisin A (Chel A), remarkably inhibits the invasive ability of human invasive BC cells through downregulation of SOX2 protein expression. We found that ChlA-F treatment dramatically decreases SOX2 protein expression in human high-grade invasive BC cells. Ectopic expression of SOX2 reversed ChlA-F inhibition of cell invasion ability in human bladder cancer cells, suggesting that SOX2 is a major target of ChlA-F during its inhibition of human BC invasion. Mechanistic studies revealed that ChlA-F downregulates SOX2 at both the protein degradation and protein translation levels. Further studies revealed that ChlA-F treatment induces HuR protein expression and that the increased HuR interacts with USP8 mRNA, resulting in elevation of USP8 mRNA stability and protein expression. Elevated USP8 subsequently acts as an E3 ligase to promote SOX2 ubiquitination and protein degradation. We also found that ChlA-F treatment substantially increases c-Jun phosphorylation at Ser63 and Ser73, initiating miR-200c transcription. The increased miR-200c directly binds to the 3′-UTR of SOX2 mRNA to suppress SOX2 protein translation. These results present novel mechanistic insight into understanding SOX2 inhibition upon ChlA-F treatment and provide important information for further exploration of ChlA-F as a new therapeutic compound for the treatment of highly invasive/metastatic human BC patients.
VcINDY, the sodium-dependent dicarboxylate transporter from Vibrio cholerae, is responsible for C4-carboxylate uptake into cells. The molecular mechanism of how VcINDY physically moves substrates across the membrane, and does so in an energetically efficient manner, is unclear. Here, we use single-molecule fluorescence resonance energy transfer experiments to directly observe the individual mechanistic steps that VcINDY takes to translocate substrates across a lipid bilayer, and then test key predictions of transport cycle mechanistic models. Our data provide the first direct, dynamic evidence that VcINDY undergoes stochastic, elevator-type conformational motions that enable substrate translocation. The dynamics of these elevator motions are approximately an order of magnitude faster than the turnover rate for substrate transport, demonstrating that VcINDY undergoes multiple rounds of substrate translocation before a productive transport cycle is completed. Furthermore, the two protomers of the VcINDY homodimer undergo the substrate translocation motions in a noncooperative manner, and thus likely engage in independent transport reactions. The relative substrate independence of those motions supports the notion that the VcINDY transport cycle maintains strict cosubstrate coupling by a mechanism other than translocation inhibition. Thermodynamic modeling provides insight into how a cooperative binding mechanism is one such generalized approach to optimizing transport for many secondary active transporters.
Therapies that harness the immune system to target and eliminate tumour cells have revolutionized cancer care. Immune checkpoint blockade (ICB), which boosts the anti-tumour immune response by inhibiting negative regulators of T cell activation1-3, is remarkably successful in a subset of cancer patients. Yet a significant proportion do not respond to treatment, emphasizing the need to understand factors influencing the therapeutic efficacy of ICB4-9. The gut microbiota, consisting of trillions of microorganisms residing in the gastrointestinal tract, has emerged as a critical determinant of immune function and response to cancer immunotherapy, with several studies demonstrating association of microbiota composition with clinical response10-16. However, a mechanistic understanding of how gut commensal bacteria influence the efficacy of ICB remains elusive. Here we use a gut commensal microorganism, segmented filamentous bacteria (SFB), which induces an antigen-specific T helper 17 (TH17) cell effector program in the small intestine lamina propria (SILP)17, to investigate how colonization with this microbe affects the efficacy of ICB in restraining distal growth of tumours sharing antigen with SFB. We find that anti-programmed cell death protein 1 (PD-1) treatment effectively inhibits the growth of implanted SFB antigen-expressing melanoma only if mice are colonized with SFB. Through T cell receptor (TCR) clonal lineage tracing, fate mapping and peptide-major histocompatability complex (MHC) tetramer staining, we identify tumour-associated SFB-specific T helper 1 (TH1)-like cells derived from the homeostatic TH17 cells induced by SFB colonization in the SILP. These gut-educated ex-TH17 cells produce high levels of the pro-inflammatory cytokines interferon (IFN)-γ and tumour necrosis factor (TNF) within the tumour microenvironment (TME), enhancing antigen presentation and promoting recruitment, expansion and effector functions of CD8+ tumour-infiltrating cytotoxic lymphocytes and thereby enabling anti-PD-1-mediated tumour control. Conditional ablation of SFB-induced IL-17A+CD4+ T cells, precursors of tumour-associated TH1-like cells, abolishes anti-PD-1-mediated tumour control and markedly impairs tumour-specific CD8+ T cell recruitment and effector function within the TME. Our data, as a proof of principle, define a cellular pathway by which a single, defined intestinal commensal imprints T cell plasticity that potentiates PD-1 blockade, and indicate targeted modulation of the microbiota as a strategy to broaden ICB efficacy.
OBJECTIVE:Using a hydroxychloroquine (HCQ) dose of 5 mg/kg/day in systemic lupus erythematosus (SLE) is associated with a higher risk of flares; HCQ blood level monitoring could be a better way to adjust the HCQ dose. We studied the upper threshold for a reference range of HCQ levels to inform routine monitoring. METHODS:This observational study included patients (N = 2,010) across the Systemic Lupus International Collaborating Clinics, Wisconsin, international, and French studies who underwent HCQ blood level measurements. Using adjusted spline and logistic regression analyses on the cross-sectional data, we first identified an HCQ blood level associated with higher HCQ toxicity. Next, we tested if this upper threshold level was supratherapeutic (no further risk reduction for the Systemic Lupus Erythematosus Disease Activity Index 2000 [score ≥6]). Finally, we examined associations between chronic kidney disease (CKD) stage and supratherapeutic (toxic) HCQ blood levels. RESULTS:Among 1,842 patients (excluding 168 patients with very low HCQ blood levels), 4.9% had HCQ-related toxicity. Odds of toxicity were 2.1-fold higher with blood levels ≥1,150 ng/mL and 1.7-fold higher with the cumulative HCQ dose per 1,000-g increase. Blood levels ≥1,150 ng/mL were associated with a saturation in therapeutic effect, indicating supratherapeutic levels. Patients with CKD stage ≥3 had 2.3-fold higher odds of having supratherapeutic levels (≥1,150 ng/mL). CONCLUSION:The therapeutic reference range for HCQ blood level monitoring is 750 to <1,150 ng/mL. HCQ level monitoring could optimize HCQ use, particularly in patients with CKD stage ≥3. Future longitudinal studies are needed to validate the use of HCQ blood level monitoring in optimizing dosing.
