ReviewDevelopmental Therapeutics Consortium report on study design effects on trial outcomes in chronic myeloid leukaemia.
Tyrosine kinase inhibitors (TKIs) have dramatically changed the treatment of chronic myeloid leukaemia (CML). Results from ongoing phase 3 trials with nilotinib [Efficacy and Safety in Clinical Trials-Newly Diagnosed Patients (ENESTnd)] and dasatinib [Dasatinib Versus Imatinib Study in Treatment-Naive CML-CP Patients (DASISION)] in newly diagnosed patients with CML in chronic phase have demonstrated that these TKIs resulted in significant improvements in responses vs. imatinib. ⋯ Despite potential bias from differences in patient populations and study design, indirect cross-trial comparisons to determine the relative effectiveness of these agents will be performed by physicians. This DTC report provides a comprehensive summary of the study designs, protocols and results of the ENESTnd and DASISION trials, which will assist physicians in making informed decisions on the best treatment approach for their patients.

ReviewImmunological pathways in virus-induced COPD exacerbations: a role for IL-15.
Chronic obstructive pulmonary disease (COPD) is characterized by high levels of antiviral type 1 cytokine interferon-γ and activated CD8(+) T cells. COPD exacerbations are the major cause of morbidity and mortality, have a prolonged and intense effect on quality of life and may result in accelerated loss of lung function. Respiratory virus infections, frequently within a state of colonization by bacteria, are the major cause of COPD exacerbations, and there is also evidence of virus latency in 'stable' disease, suggesting that latent infection might be a cause of chronic inflammation in COPD. ⋯ Interleukin-15 could play a major role in the airway inflammation in COPD directly, via its own receptors, by amplifying the type 1 immune responses and decreasing apoptosis or indirectly, via modulating molecules associated with cytotoxic activity of natural killer and CD8(+) T cells, such as major histocompatibility complex class I-related chain A and B.
