Randomized Controlled Trial Multicenter Study Comparative StudyEtirinotecan pegol (NKTR-102) versus treatment of physician's choice in women with advanced breast cancer previously treated with an anthracycline, a taxane, and capecitabine (BEACON): a randomised, open-label, multicentre, phase 3 trial.
New options are needed for patients with heavily pretreated breast cancer. Etirinotecan pegol is a long-acting topoisomerase-I inhibitor that prolongs exposure to, but reduces the toxicity of, SN38 (the active metabolite of irinotecan). We assessed whether etirinotecan pegol is superior to currently available treatments for patients with previously treated, locally recurrent or metastatic breast cancer. ⋯ Nektar Therapeutics.

ReviewMultifunctional receptor-targeting antibodies for cancer therapy.
During the past decade, monospecific antibodies targeting cell-surface receptors in different tumour types have achieved substantial success and have been at the forefront of cancer treatment. However, redundant signalling and crosstalk between different pathways within tumour cells and between tumour cells and their microenvironment can limit the efficacy of receptor-targeted monospecific-based therapies. ⋯ In this Review, we discuss the rationales and strategies for the use of multifunctional receptor-targeting antibodies, their mechanisms of action, and the promises and challenges they hold as cancer therapeutics. This knowledge provides opportunities to improve current targeted therapy outcomes for patients with cancer.

Multicenter StudyOrgan preservation for clinical T2N0 distal rectal cancer using neoadjuvant chemoradiotherapy and local excision (ACOSOG Z6041): results of an open-label, single-arm, multi-institutional, phase 2 trial.
Local excision is an organ-preserving treatment alternative to transabdominal resection for patients with stage I rectal cancer. However, local excision alone is associated with a high risk of local recurrence and inferior survival compared with transabdominal rectal resection. We investigated the oncological and functional outcomes of neoadjuvant chemoradiotherapy and local excision for patients with stage T2N0 rectal cancer. ⋯ National Cancer Institute and Sanofi-Aventis.

Randomized Controlled TrialBevacizumab with or without erlotinib as maintenance therapy in patients with metastatic colorectal cancer (GERCOR DREAM; OPTIMOX3): a randomised, open-label, phase 3 trial.
The combination of an anti-VEGF or an anti-EGFR-targeted monoclonal antibody with chemotherapy has shown clinical activity in patients with metastatic colorectal cancer. However, combining both anti-VEGF and anti-EGFR antibodies with chemotherapy in first-line treatment resulted in adverse outcomes. We assessed whether the combination of erlotinib, an EGFR tyrosine kinase inhibitor, with bevacizumab could increase the efficacy of maintenance therapy in patients with unresectable metastatic colorectal cancer. ⋯ GERCOR and F Hoffmann-La Roche.
