Capecitabine compared with observation in resected biliary tract cancer (BILCAP): a randomised, controlled, multicentre, phase 3 study.

BACKGROUND: Despite improvements in multidisciplinary management, patients with biliary tract cancer have a poor outcome. Only 20% of patients are eligible for surgical resection with curative intent, with 5-year overall survival of less than 10% for all patients. To our knowledge, no studies have described a benefit of adjuvant therapy. We aimed to determine whether adjuvant capecitabine improved overall survival compared with observation following surgery for biliary tract cancer. METHODS: This randomised, controlled, multicentre, phase 3 study was done across 44 specialist hepatopancreatobiliary centres in the UK. Eligible patients were aged 18 years or older and had histologically confirmed cholangiocarcinoma or muscle-invasive gallbladder cancer who had undergone a macroscopically complete resection (which includes liver resection, pancreatic resection, or, less commonly, both) with curative intent, and an Eastern Cooperative Oncology Group performance status of less than 2. Patients who had not completely recovered from previous surgery or who had previous chemotherapy or radiotherapy for biliary tract cancer were also excluded. Patients were randomly assigned 1:1 to receive oral capecitabine (1250 mg/m2 twice daily on days 1-14 of a 21-day cycle, for eight cycles) or observation commencing within 16 weeks of surgery. Treatment was not masked, and allocation concealment was achieved with a computerised minimisation algorithm that stratified patients by surgical centre, site of disease, resection status, and performance status. The primary outcome was overall survival. As prespecified, analyses were done by intention to treat and per protocol. This study is registered with EudraCT, number 2005-003318-13. FINDINGS: Between March 15, 2006, and Dec 4, 2014, 447 patients were enrolled; 223 patients with biliary tract cancer resected with curative intent were randomly assigned to the capecitabine group and 224 to the observation group. The data cutoff for this analysis was March 6, 2017. The median follow-up for all patients was 60 months (IQR 37-60). In the intention-to-treat analysis, median overall survival was 51·1 months (95% CI 34·6-59·1) in the capecitabine group compared with 36·4 months (29·7-44·5) in the observation group (adjusted hazard ratio [HR] 0·81, 95% CI 0·63-1·04; p=0·097). In a protocol-specified sensitivity analysis, adjusting for minimisation factors and nodal status, grade, and gender, the overall survival HR was 0·71 (95% CI 0·55-0·92; p=0·010). In the prespecified per-protocol analysis (210 patients in the capecitabine group and 220 in the observation group), median overall survival was 53 months (95% CI 40 to not reached) in the capecitabine group and 36 months (30-44) in the observation group (adjusted HR 0·75, 95% CI 0·58-0·97; p=0·028). In the intention-to-treat analysis, median recurrence-free survival was 24·4 months (95% CI 18·6-35·9) in the capecitabine group and 17·5 months (12·0-23·8) in the observation group. In the per-protocol analysis, median recurrence-free survival was 25·9 months (95% CI 19·8-46·3) in the capecitabine group and 17·4 months (12·0-23·7) in the observation group. Adverse events were measured in the capecitabine group only, and of the 213 patients who received at least one cycle, 94 (44%) had at least one grade 3 toxicity, the most frequent of which were hand-foot syndrome in 43 (20%) patients, diarrhoea in 16 (8%) patients, and fatigue in 16 (8%) patients. One (<1%) patient had grade 4 cardiac ischaemia or infarction. Serious adverse events were observed in 47 (21%) of 223 patients in the capecitabine group and 22 (10%) of 224 patients in the observation group. No deaths were deemed to be treatment related. INTERPRETATION: Although this study did not meet its primary endpoint of improving overall survival in the intention-to-treat population, the prespecified sensitivity and per-protocol analyses suggest that capecitabine can improve overall survival in patients with resected biliary tract cancer when used as adjuvant chemotherapy following surgery and could be considered as standard of care. Furthermore, the safety profile is manageable, supporting the use of capecitabine in this setting. FUNDING: Cancer Research UK and Roche.

Long-term impact of liver function on curative therapy for hepatocellular carcinoma: application of the ALBI grade.

BACKGROUND: Application of curative therapy for hepatocellular carcinoma is crucially dependent on underlying liver function. Using the recently described ALBI grade we examined the long-term impact of liver dysfunction on survival of early-stage hepatocellular carcinoma (HCC) patients. METHODS: This cohort study comprised 2559 HCC patients from different geographic regions, all treated with curative intent. We also examined the relation between indocyanine green (ICG) clearance and ALBI score. Survival was measured from the date of treatment to the date of death or last follow-up. RESULTS: The ALBI score correlated well with ICG clearance. Among those undergoing surgical resection, patients with ALBI grade-1 (good liver function) survived approximately twice as long as those with ALBI grade-2 (less good liver function), although more than 90% of these patients were classified as Child-Pugh (C-P) grade A. In the cohort receiving ablative therapies, there was a similar difference in survival between ALBI grade-1 and grade-2. Cox regression analysis confirmed that the ALBI score along with age, gender, aetiology and tumour factors (AFP, tumour size/number and vascular invasion) independently influenced survival in HCC patients receiving curative treatments. CONCLUSIONS: The ALBI score represents a simple approach to the assessment of liver function in patients with HCC. After potentially curative therapy, those with ALBI grade-1 survived approximately twice as long as those with ALBI grade-2. These data suggest that ALBI grade-1 patients are appropriately treated with surgical resection whereas ALBI grade-2 patients may, where the option exists, be more suitable for liver transplantation or the less invasive curative ablative therapies.

Investigating the safety and activity of the use of BTT1023 (Timolumab), in the treatment of patients with primary sclerosing cholangitis (BUTEO): A single-arm, two-stage, open-label, multi-centre, phase II clinical trial protocol.

INTRODUCTION: Primary sclerosing cholangitis (PSC) is a progressive inflammatory liver disease characterised by relentless liver fibrosis and a high unmet need for new therapies. Preventing fibrosis represents an important area of interest in the development of vital new drugs. Vascular adhesion protein-1 (VAP-1) drives inflammation in liver disease, and provision of an antibody against VAP-1 blunts fibrosis in murine models of liver injury. METHODS AND ANALYSIS: BUTEO is a single-arm, two-stage, open-label, multi-centre, phase II clinical trial. Up to 59 patients will receive treatment with anti-VAP monoclonal antibody, BTT1023, over a 78-day treatment period. Adults with PSC and a serum alkaline phosphatase (ALP) of at least 1.5 times the upper limit of normal will be included. Our primary outcome measure is a reduction in ALP by >25% from baseline to Day 99. Secondary outcome measures include safety and tolerability, changes pre therapy/post therapy in circulating serum VAP-1 as well as imaging findings. The first patient participant was recruited on 08 September 2015. ETHICS AND DISSEMINATION: This protocol has been approved by the Research Ethics Committee (REC, reference 14/EM/1272). The first REC approval date was 06 January 2015 with three subsequent approved amendments. This article refers to protocol V3.0, dated 16 March 2016. Results will be disseminated via peer-reviewed publication and presentation at international conferences. TRIAL REGISTRATION: The trial is registered with the European Medicines agency (EudraCT: 2014-002393-37), the National Institute for Health Research (Portfolio ID: 18051) and ISRCTN: 11233255. The clinicaltrials.gov identifier is NCT02239211. Pre-results.

Osteopenia in exercise-associated amenorrhea using ballet dancers as a model: a longitudinal study.

Few longitudinal studies have investigated the effects of amenorrhea and amenorrhea plus exercise on bone mineral density (BMD) of young women. We carried out a 2-yr comparison of dancers and nondancers, both amenorrheic and normal, that investigated the role of hypothalamic amenorrhea on bone in this context. We studied 111 subjects (mean age, 22.4 +/- 4.6 yr; age of menarche, 14.1 +/- 2.2 yr), including 54 dancers, 22 with hypothalamic amenorrhea, and 57 nondancers, 22 with hypothalamic amenorrhea. Detailed hormonal and nutritional data were obtained in all groups to determine possible causal relationship to osteoporosis. The amenorrheic groups, dancers and nondancers, both showed reduced BMD in the spine, wrist, and foot, which remained below controls throughout the 2 yr. Only amenorrheic dancers showed significant changes in spine BMD (12.1%; P < 0.05) but still remained below controls, and within this subgroup, only those with delayed menarche showed a significant increase. The seven amenorrheic subjects (three dancers and four nondancers) who resumed menses during the study showed an increase in spine and wrist BMD (17%; P < 0.001) without achieving normalization. Delayed menarche was the only variable that predicted stress fractures (P < 0.005), which we used as a measure of bone functional strength. Analysis of dieting and nutritional patterns showed higher incidence of dieting behavior in this group, as manifested by higher Eating Attitudes Test scores (16.3 +/- 2.00 vs. 11.5 +/- 1.45; P < 0.05) and higher fiber intakes (30.7 +/- 3.00 vs. 17.5 +/- 2.01 g/24 h; P < 0.001). We concluded that low bone mass occurs in young women with amenorrhea and delayed menarche, both exercisers and nonexercisers. Crucial bone mass accretion may be compromised by their reproductive and nutritional health.

Persistent osteopenia in ballet dancers with amenorrhea and delayed menarche despite hormone therapy: a longitudinal study.

OBJECTIVE: To investigate the role of estrogen deprivation and replacement in amenorrheic and nonamenorrheic dancers on hormone therapy and calcium. DESIGN: Clinical, placebo-controlled, randomized trial study.Healthy volunteers in an academic research environment. PATIENT(S): Fifty-five dancers (mean age: 22.0 +/- 4.6, age at menarche: 14.7 +/- 2.3 years), including 24 amenorrheics. INTERVENTION(S): Amenorrheics were randomized in a controlled trial to receive placebo or Premarin, 0.625 mg for 25 days monthly, with Provera, 10 mg, for 10 of these 25 days (hormone therapy) for 2 years. These women were compared to normally menstruating controls. The study participants also received 1250 mg of calcium per day. MAIN OUTCOME MEASURE(S): Bone mineral density (BMD) measured at the foot, wrist, and lumbar spine. Our overall results showed no difference in BMD between the treated or placebo groups, indicating that hormone therapy did not change or normalize BMD when compared to normals. Five patients (all on placebo) who resumed menses during the study showed an increase in BMD without normalization. CONCLUSION(S): These findings suggest that mechanisms other than hypoestrogenism may be involved with the osteopenia associated with exercise-induced amenorrhea.
