Dose Adjustments

  • For hematologic toxicities, omacetaxine treatment cycles may be delayed.
  • If a patient experiences Grade 4 neutropenia (absolute neutrophil count (ANC) less than 0.5 x 10(9)/L) or Grade 3 thrombocytopenia (platelet counts less than 50 x 10(9)/L) during a cycle, delay starting the next cycle until ANC is greater than or equal to 1.0 x 10(9)/L and platelet count is greater than or equal to 50 x 10(9)/L. Also, for the next cycle, reduce the number of dosing days by 2 days (e.g. to 12 or 5 days).
  • For other clinically significant nonhematologic toxicity manage symptomatically. Interrupt and/or delay omacetaxine until toxicity is resolved.
