Randomized Controlled Trial Multicenter StudyAddition of ramucirumab or merestinib to standard first-line chemotherapy for locally advanced or metastatic biliary tract cancer: a randomised, double-blind, multicentre, phase 2 study.
Biliary tract cancers are aggressive, rare, gastrointestinal malignancies with a poor prognosis; approximately half of patients with these cancers survive for less than 1 year after diagnosis with advanced disease. We aimed to evaluate the efficacy and safety of ramucirumab or merestinib in addition to first-line cisplatin-gemcitabine in patients with locally advanced or metastatic biliary tract cancer. ⋯ Eli Lilly and Company.

Randomized Controlled TrialMaintenance with daratumumab or observation following treatment with bortezomib, thalidomide, and dexamethasone with or without daratumumab and autologous stem-cell transplant in patients with newly diagnosed multiple myeloma (CASSIOPEIA): an open-label, randomised, phase 3 trial.
CASSIOPEIA part 1 showed superior depth of response and significantly improved progression-free survival with daratumumab, bortezomib, thalidomide, and dexamethasone (D-VTd) versus bortezomib, thalidomide, and dexamethasone (VTd) as induction and consolidation in patients with autologous stem-cell transplant (ASCT)-eligible newly diagnosed multiple myeloma. In part 2, we compared daratumumab maintenance versus observation only. ⋯ Janssen Research & Development, the Intergroupe Francophone du Myélome, and the Dutch-Belgian Cooperative Trial Group for Hematology Oncology.

Over the past two decades, targeted therapies have become cornerstone treatments for numerous cancers with oncogene addiction. Unfortunately, their effectiveness reduces over time and most patients who receive targeted therapies relapse within 12 months. The emergence of drug-resistance mechanisms in tumours paved the way for next-generation inhibitors. ⋯ This scenario has led us to propose a new concept in clinical drug development: the late phase 1 study. The primary goal of this type of trial is to define an alternative MTD of a drug in patients who are chronically exposed and had an initial benefit from targeted therapy but subsequently progressed without an identified resistance alteration. Intrapatient dose escalation might increase drug concentration and restore drug activity or efficacy.

ReviewBasket clinical trial design for targeted therapies for cancer: a French National Authority for Health statement for health technology assessment.
During the past decade, health technology assessment bodies have faced new challenges in establishing the benefits of new drugs for individuals and health-care systems. A topic of increasing importance to the field of oncology is the so-called agnostic regulatory approval of targeted therapies for cancer (independent of tumour location and histology) granted on the basis of basket trials. Basket trials in oncology offer the advantage of simultaneously evaluating treatments for multiple tumours, even rare cancers, in a single clinical trial. ⋯ The requirements of this approach include the need for randomisation, clinically relevant endpoints, appropriate correction for multiple significance testing, characterisation of subgroup heterogeneity, and validation of underlying biomarker assays. A prospectively designated external control is encouraged when the implementation of a direct comparison is deemed infeasible. We also underline the importance of recording outcomes from basket trials in a registry for use as future external controls.
