ReviewIntegrating predictive biomarkers and classifiers into oncology clinical development programmes.
The future of drug development in oncology lies in identifying subsets of patients who will benefit from particular therapies, using predictive biomarkers. These technologies offer hope of enhancing the value of cancer medicines and reducing the size, cost and failure rates of clinical trials. ⋯ Here, we present methods to adaptively integrate predictive biomarkers into clinical programmes in a data-driven manner, wherein these biomarkers are emphasized in exact proportion to the evidence supporting their clinical predictive value. The resulting programme demands value from predictive biomarkers and is designed to optimally harvest this value for oncology drug development.

Transient receptor potential (TRP) cation channels have been among the most aggressively pursued drug targets over the past few years. Although the initial focus of research was on TRP channels that are expressed by nociceptors, there has been an upsurge in the amount of research that implicates TRP channels in other areas of physiology and pathophysiology, including the skin, bladder and pulmonary systems. In addition, mutations in genes encoding TRP channels are the cause of several inherited diseases that affect a variety of systems including the renal, skeletal and nervous system. This Review focuses on recent developments in the TRP channel-related field, and highlights potential opportunities for therapeutic intervention.

ReviewJanus kinase inhibitors for the treatment of myeloproliferative neoplasias and beyond.
Recent advances in our understanding of the pathogenesis of the Philadelphia chromosome-negative myeloproliferative neoplasms, polycythaemia vera, essential thrombocythaemia and myelofibrosis have led to the identification of the mutation V617F in Janus kinase (JAK) as a potential therapeutic target. This information has prompted the development of ATP-competitive JAK2 inhibitors. ⋯ Because JAKs are involved in the pathogenesis of inflammatory and immune-mediated disorders, JAK inhibitors are also being tested in clinical trials in patients with rheumatoid arthritis and psoriasis, as well as for the treatment of other autoimmune diseases and for the prevention of allograft rejection. Preliminary results indicate that these agents hold great promise for the treatment of JAK-driven disorders.
