Interleukin-11 (IL-11) is a novel cytokine that has been shown to stimulate human hematopoietic progenitors including the CD34+ CD33- DR- early progenitors. IL-11 has little effect on its own but it synergizes with other hematopoietic growth factors. We investigated the recovery of human myeloid progenitors incubated with IL-11 alone or in combination with other cytokines, including stem cell factor (SCF), interleukin-3 (IL-3) and granulocyte macrophage colony-stimulating factor (GM-CSF) following their in vitro treatment with ARA-C (10(-9) M) or Eilatin (10(-7) M). IL-11 in combination with IL-3 and GM-CSF markedly increased CFU-C colony growth pre- and post-ARA-C or Eilatin incubation from CML and normal individual bone marrow (BM) cells. Similarly, IL-11 alone or in combination with other cytokines increased cell recovery following 7-day suspension culture. A decrease in BCR/ABL fusion product was observed (by FISH analysis) after incubation of BM cells from CML patients in liquid culture for 7 days with 10(-9) M ARA-C or 10(-7) M Eilatin in the presence of IL-11 alone or in combination with other cytokines. These results indicate that following cytoreductive therapy IL-11 may enhance to a greater extent the growth of normal myeloid progenitors than the malignant clone and may, therefore, be of clinical importance for CML patients treated with chemotherapeutic agents.

During therapy with imatinib (Gleevec), 20-30% of patients with CML in chronic phase develop grade > or =3 thrombocytopenia. This leads to treatment interruptions and dose reductions that result in a decreased probability of achieving a cytogenetic response. Interleukin-11 (oprelvekin) is a megakaryopoietic cytokine that reduces the incidence and severity of thrombocytopenia associated with chemotherapy. We report on the use of interleukin-11 in three CML patients with grade > or =3, imatinib-induced thrombocytopenia. In all three patients, interleukin-11 led to improved platelets, uninterrupted administration of imatinib and improved cytogenetic response. This observation suggests that interleukin-11 may be beneficial for patients with imatinib-induced thrombocytoepnia.
