New drugs for the treatment of non-Hodgkin lymphomas
Non-Hodgkin lymphomas (NHL) are diverse diseases either of mature B-cell or T-cell derivation. Despite being generally chemosensitive diseases, the last decade has focused on developing more targeted agents based on improved insights of underlying biology. The hope is that more targeted and biologically rational treatments will improve both the efficacy and toxicity profile of standard approaches, with the ultimate goal of improving clinical outcomes. Among the newest agents to be approved are inhibitors of B-cell receptor (BCR) and PI3K signaling; however, a number of other classes of agents such as selective inhibitors of nuclear export (SINE), inhibitors of immune regulation such as PD1 inhibitors, and small molecule inhibitors of apoptosis are on the horizon. In addition, growing clinical evidence supports continued and new applications for immunomodulatory agents, proteasome inhibitors and histone deacetylase inhibitors. Altogether, this is an exciting time for NHL, with a number of promising agents and early clinical data. The key path forward will be to better apply these new agents in a personalized way, which will hopefully constitute the next generation of trials.
