Capsaicin is a potent agonist of the TRPV1 channel, a transduction channel that is highly expressed in nociceptive fibers (pain fibers) throughout the peripheral nervous system. Given the importance of TRPV1 as one of several transduction channels in nociceptive fibers, much research has been focused on the potential therapeutic benefits of using TRPV1 antagonists for the management of pain. However, an antagonist has two limitations.

Background: Lung remodeling and pulmonary fibrosis are serious, life-threatening conditions resulting from diseases such as chronic severe asthma and idiopathic pulmonary fibrosis (IPF). Preclinical evidence suggests that JNK enzyme function is required for key steps in the pulmonary fibrotic process. However, a selective JNK inhibitor has not been investigated in translational models of lung fibrosis with clinically relevant biomarkers, or in IPF patients.

Phosphodiesterase 4 (PDE4) is a key enzyme in the degradation of cyclic adenosine monophosphate and is centrally involved in the cytokine production of inflammatory cells, angiogenesis, and the functional properties of other cell types such as keratinocytes. In this review article, apremilast, a novel small molecule inhibitor of PDE4, is introduced. Apremilast has profound anti-inflammatory properties in animal models of inflammatory disease, as well as human chronic inflammatory diseases such as psoriasis and psoriatic arthritis.

There is great concern about clearly defining benefit and risk in the context of both drug development and clinical practice. In view of this pressure, the OMERACT Executive identified the need to bring together clinical trialists, pharmacoepidemiologists, clinicians, clinical epidemiologists, statistical experts, and regulatory representatives to discuss different approaches to define risk and perhaps improved ways to express it. Each attendee spoke on a given topic and the group was charged to consider the issue of risk in the context of formally posed questions.
