Protein synthesis inhibitors of natural origin for CML therapy: semisynthetic homoharringtonine (Omacetaxine mepesuccinate).
Omacetaxine mepesuccinate is a drug approved in 2014 by FDA for the use in CML therapy in patients resistant to at least two thymidine kinase inhibitors (TKIs). It possesses unique mechanism of anticancer activity that is principally different from mechanism of activity of TKIs. Omacetaxine mepesuccinate inhibits protein translation through prevention of the initial elongation step of protein synthesis and its use benefits CML patients possessing the BCR-ABL oncogene. Because of the superior activity of Omacetaxine in patients who became resistant to therapy with TKIs, FDA decided on the accelerated approval of this drug taking its consideration not only its activity as such but also a favorable benefit-to-risk profile in patients included into clinical studies.
