Background: Adjuvant abemaciclib combined with endocrine therapy (ET) previously demonstrated clinically meaningful improvement in invasive disease-free survival (IDFS) and distant relapse-free survival (DRFS) in hormone receptor-positive, human epidermal growth factor receptor 2-negative, node-positive, high-risk early breast cancer at the second interim analysis, however follow-up was limited. Here, we present results of the prespecified primary outcome analysis and an additional follow-up analysis. Patients and methods: This global, phase III, open-label trial randomized (1 : 1) 5637 patients to adjuvant ET for !5 years AE abemaciclib for 2 years. Cohort 1 enrolled patients with !4 positive axillary lymph nodes (ALNs), or 1-3 positive ALNs and either grade 3 disease or tumor !5 cm. Cohort 2 enrolled patients with 1-3 positive ALNs and centrally determined high Ki-67 index (!20%). The primary endpoint was IDFS in the intent-to-treat population (cohorts 1 and 2). Secondary endpoints were IDFS in patients with high Ki-67, DRFS, overall survival, and safety. Results: At the primary outcome analysis, with 19 months median follow-up time, abemaciclib þ ET resulted in a 29% reduction in the risk of developing an IDFS event [hazard ratio (HR) ¼ 0.71, 95% confidence interval (CI) 0.58-0.87; nominal P ¼ 0.0009]. At the additional follow-up analysis, with 27 months median follow-up and 90% of patients off treatment, IDFS (HR ¼ 0.70, 95% CI 0.59-0.82; nominal P < 0.0001) and DRFS (HR ¼ 0.69, 95% CI 0.57-0.83; nominal P < 0.0001) benefit was maintained. The absolute improvements in 3-year IDFS and DRFS rates were 5.4% and 4.2%, respectively. Whereas Ki-67 index was prognostic, abemaciclib benefit was consistent regardless of Ki-67 index. Safety data were consistent with the known abemaciclib risk profile. Conclusion: Abemaciclib þ ET significantly improved IDFS in patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative, node-positive, high-risk early breast cancer, with an acceptable safety profile. Ki-67 index was prognostic, but abemaciclib benefit was observed regardless of Ki-67 index. Overall, the robust treatment benefit of abemaciclib extended beyond the 2-year treatment period.

This study, one of the largest phase II trials performed in this disease, shows interesting activity of the combination of 5-FU and cisplatin in advanced biliary tract carcinoma.

The combination of CDDP and 5-FU in continuous infusion seems an active and well tolerated treatment in APC and will be compared to standard therapy in a multicentric randomized trial.

Background Cancer patients with acute venous thromboembolism (VTE) receiving anticoagulant treatment have an increased bleeding risk. Objectives We performed a prespecified secondary analysis of the randomized, open-label, Phase III CATCH trial (NCT01130025) to assess the rate and sites of and the risk factors for clinically relevant bleeding (CRB). Patients/Methods Patients with active cancer and acute, symptomatic VTE received either tinzaparin 175 IU kg once daily or warfarin (target International Normalized Ratio [INR] of 2.0-3.0) for 6 months. Fisher's exact test was used to screen prespecified clinical risk factors; those identified as being significantly associated with an increased risk of CRB then underwent competing risk regression analysis of time to first CRB. Results Among 900 randomized patients, 138 (15.3%) had 180 CRB events. CRB occurred in 60 patients (81 events) in the tinzaparin group and in 78 patients (99 events) in the warfarin group (hazard ratio [HR] 0.64; 95% confidence interval [CI] 0.45-0.89). Common bleeding sites were gastrointestinal (36.7%; n = 66), genitourinary (22.8%; n = 41), and nasal (10.0%; n = 18). In multivariate analysis, the risk of CRB increased with age > 75 years (HR 1.83, 95% CI 1.14-2.94) and intracranial malignancy (HR 1.97, 95% CI 1.07-3.62). In the warfarin group, 40.4% of CRB events occurred in patients with with an INR of < 3.0. A lower time in therapeutic range was associated with a higher risk of CRB. Conclusions CRB is a frequent complication in cancer patients with VTE during anticoagulant treatment, and is associated with age > 75 years and intracranial malignancy.
