Introduction: Aortic stenosis (AS) is common affecting >13% of adults over the age of 75 years. In people who develop symptoms, without valve replacement, prognosis is dismal with mortality as high as 50% at 1 year. In asymptomatic patients, the timing of valve intervention is less well defined and a strategy of watchful waiting is recommended. Many, however, may develop symptoms and attribute this to age related decline, rather than worsening AS. Timely intervention in asymptomatic severe AS is critical, since delayed intervention often results in poor outcomes. Proactive surveillance of symptoms, quality of life and functional capacity should enable timely identification of people who will benefit from aortic valve replacement. There are no data however, to support the clinical and cost effectiveness of such an approach in a healthcare setting in the UK. The aim of this pilot trial is to test the feasibility of a full-scale randomised controlled trial (RCT) to determine the utility of proactive surveillance in people with asymptomatic severe AS to guide the timing of intervention., Methods and Analysis: APRAISE-AS is a multi-centre, non-blinded, two-arm, parallel group randomised controlled trial of up to 66 participants aged >18 years with asymptomatic severe AS. Participants will be randomised to either standard care or standard care supplemented with the APRAISE-AS intervention. Primary outcomes will capture; adherence to and participant acceptability of the intervention, recruitment and retention rates, and completeness of data collection. The findings will be used to inform the sample size and most appropriate outcome measure(s) for a full-scale RCT and health economic evaluation., Ethics and Dissemination: Ethical approval was granted by the Black Country REC, reference: 22/WM/0214. Results will be submitted for publication in peer-reviewed journals and disseminated at local, regional and national meetings where appropriate., Trial Registration Number: ISRCTN19413194 registered on 14.07.2023., Competing Interests: Competing interests: LF reports grants from the BHF (AA/18/2/34218), EU Horizon 2020 CATCH ME (grant agreement number 633196), MAESTRIA (grant agreement number 965286), AFFECT-EU (grant agreement number 847770, NIHR award 1002898 (APRAISE-AS) at University of Birmingham, and German Center for Cardiovascular Research (DZHK).

Purpose: The BILCAP study described a modest benefit for capecitabine as adjuvant therapy for curatively resected biliary tract cancer (BTC), and capecitabine has become the standard of care. We present the long-term data and novel exploratory subgroup analyses., Methods: This randomized, controlled, multicenter, phase III study recruited patients age 18 years or older with histologically confirmed cholangiocarcinoma or muscle-invasive gallbladder cancer after resection with curative intent and an Eastern Cooperative Oncology Group performance status of < 2. Patients were randomly assigned 1:1 to receive oral capecitabine (1,250 mg/m 2 twice daily on days 1-14 of a 21-day cycle, for eight cycles) or observation. The primary outcome was overall survival (OS). This study is registered with EudraCT 2005-003318-13., Results: Between March 15, 2006, and December 4, 2014, 447 patients were enrolled; 223 patients with BTC resected with curative intent were randomly assigned to the capecitabine group and 224 to the observation group. At the data cutoff of January 21, 2021, the median follow-up for all patients was 106 months (95% CI, 98 to 108). In the intention-to-treat analysis, the median OS was 49.6 months (95% CI, 35.1 to 59.1) in the capecitabine group compared with 36.1 months (95% CI, 29.7 to 44.2) in the observation group (adjusted hazard ratio 0.84; 95% CI, 0.67 to 1.06). In a protocol-specified sensitivity analysis, adjusting for minimization factors, nodal status, grade, and sex, the OS hazard ratio was 0.74 (95% CI, 0.59 to 0.94). We further describe the prognostic impact of R status, grade, nodal status, and sex., Conclusion: This long-term analysis supports the previous analysis, suggesting that capecitabine can improve OS in patients with resected BTC when used as adjuvant chemotherapy after surgery and should be considered as the standard of care., Competing Interests: John BridgewaterHonoraria: Merck Serono, ServierConsulting or Advisory Role: Merck Serono, Servier, Roche, Bayer, AstraZeneca, Incyte, Basilea, Taiho OncologySpeakers' Bureau: Celgene, Amgen, Bristol Myers SquibbResearch Funding: Amgen, Incyte (Inst)Travel, Accommodations, Expenses: MSD Oncology, Merck Serono, Servier, Bristol Myers Squibb/Medarex, Bristol Myers Squibb Daniel H.
