Several therapeutic agents with novel mechanisms of action are effective in killing the CLL leukemic cells, and a number of targeted agents are currently in the pipeline. The next challenge for treating CLL will be the proper integration of these novel targeted agents with the traditional chemotherapy and chemoimmunotherapy approaches. Let us consider CLL patients in different clinical settings. First, a patient aged 60 years who is otherwise healthy will be treated with possibly all the available chemotherapy and chemoimmunotherapy options, as well as the newer targeted agents. In this clinical setting sequencing of therapy is not a major concern. On the other hand, a patient aged 70 years who is already refractory to multiple lines of therapy is a good candidate for these newer drugs.
The more controversial use of these targeted agents will be in an older patient with some comorbidities and newly diagnosed CLL. In this clinical setting, should one go with traditional chemotherapy/chemoimmunotherapy approaches or consider newer targeted agents? These issues are now being addressed in clinical trials, and with acceptable toxicity profiles these newer drugs will move to the frontline setting.
