[The next step in the treatment of immune diseases: jakinibs, inhibitors of the intracellular Janus kinase]

Abstract

The next step in the treatment of immune diseases: jakinibs, inhibitors of the intracellular Janus kinase The intracellular Janus kinase (JAK) and the signal transduction and activator of transcription (STAT) proteins are involved in the whole spectrum of immune-mediated diseases. Currently, agents are developed that influence the JAK-STAT mechanism. JAK inhibitors (jakinibs) have only recently made their way into clinical practice. These agents exhibit both similarities and differences in terms of effectiveness and safety. In the coming years, results from basic and clinical research will improve our knowledge of these agents. For patients who suffer from immune-mediated diseases, their introduction appears to be a breakthrough that will offer new treatment options. One advantage over biologicals is that jakinibs can be taken orally. As with all new innovative medicines, with jakinibs one cannot escape a discussion over costs as well. The balance between the added value of jakinibs compared to biologicals, and the actual purchase prices for each of these treatment modalities, will influence the eventual positioning of jakinibs.
