The first one, in connection with classical chemotherapy, is that the evolution of the disease under treatment should follow a prescribed trajectory assuming that the drug works by increasing the cell death rates of both malignant and normal cells. In the case of the second control problem, as for targeted therapies, the drug is assumed to work by decreasing the multiplication rate of leukemic cells only, and the control objective is that the disease state reaches a desired endpoint. The solvability of the two problems as well as their stability are proved by using a general method of analysis. Some numerical simulations are included to illustrate the theoretical results and prove their applicability. The results can possibly be used to design therapeutic scenarios such that an expected clinical evolution can be achieved.<\/p>\n\n\n\n<p style=\"font-size:15px\"><strong><span class=\"has-inline-color has-black-color\">Subject Classification:<\/span><\/strong>  34H05, 93B05.<\/p>\n\n\n\n<p style=\"font-size:15px\"><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-black-color\"><strong>Keywords<\/strong>:<\/mark>  Control problem; Dynamic system; Leukemia.<\/p>\n\n\n\n<p style=\"font-size:15px\"><strong><span class=\"has-inline-color has-black-color\">Cite As:<\/span><\/strong>  Haplea I\u0218, Parajdi LG, Precup R.
