ReviewPhase 2 trial design in neuro-oncology revisited: a report from the RANO group.
Advances in the management of gliomas, including the approval of agents such as temozolomide and bevacizumab, have created an evolving therapeutic landscape in glioma treatment, thus affecting our ability to reliably use historical controls to comparatively assess the activity of new therapies. Furthermore, the increasing availability of novel, targeted agents--which are competing for a small patient population, in view of the low incidence of primary brain tumours--draws attention to the need to improve the efficiency of phase 2 clinical testing in neuro-oncology to expeditiously transition the most promising of these drugs or combinations to potentially practice-changing phase 3 trials. ⋯ Although there is still a small role for single-arm and non-comparative phase 2 designs, emphasis is placed on the potential role that comparative randomised phase 2 designs--such as screening designs, selection designs, discontinuation designs, and adaptive designs, including seamless phase 2/3 designs--can have. The rational incorporation of these designs, as determined by the specific clinical setting and the trial's endpoints or goals, has the potential to substantially advance new drug development in neuro-oncology.

Randomized Controlled Trial Multicenter StudyCelecoxib plus hormone therapy versus hormone therapy alone for hormone-sensitive prostate cancer: first results from the STAMPEDE multiarm, multistage, randomised controlled trial.
Long-term hormone therapy alone is standard care for metastatic or high-risk, non-metastatic prostate cancer. STAMPEDE--an international, open-label, randomised controlled trial--uses a novel multiarm, multistage design to assess whether the early additional use of one or two drugs (docetaxel, zoledronic acid, celecoxib, zoledronic acid and docetaxel, or zoledronic acid and celecoxib) improves survival in men starting first-line, long-term hormone therapy. Here, we report the preplanned, second intermediate analysis comparing hormone therapy plus celecoxib (arm D) with hormone therapy alone (control arm A). ⋯ Cancer Research UK, Pfizer, Novartis, Sanofi-Aventis, Medical Research Council (London, UK).

Ipilimumab in patients with melanoma and brain metastases: an open-label, phase 2 trial.
Brain metastases commonly develop in patients with melanoma and are a frequent cause of death of patients with this disease. Ipilimumab improves survival in patients with advanced melanoma. We aimed to investigate the safety and activity of this drug specifically in patients with brain metastases. ⋯ Bristol-Myers Squibb.

Clinical TNM staging is the standard method used to decide treatment for patients with non-small-cell lung cancer. Although integrated fluorodeoxyglucose (FDG) PET CT increases the accuracy of staging, it only guides direct tissue sampling. Histological assessment of mediastinal lymph nodes has traditionally been done with mediastinoscopy, a surgical procedure. ⋯ We conclude that mediastinal tissue staging should preferentially start with a complete endosonographic assessment. A surgical mediastinoscopy should be reserved for those in whom the endosonography result is negative. Further refinement of this recommendation is likely in the near future because data suggest that the confirmatory mediastinoscopy is particularly useful for patients with enlarged or FDG-avid lymph nodes.

Afatinib for patients with lung adenocarcinoma and epidermal growth factor receptor mutations (LUX-Lung 2): a phase 2 trial.
Afatinib is an irreversible ErbB-family blocker with preclinical activity in non-small-cell lung cancer (NSCLC) with EGFR mutations. We aimed to assess the efficacy of afatinib in patients with lung adenocarcinoma and EGFR mutations. ⋯ Boehringer Ingelheim Inc.
