Definitions

  • the present invention relates to kinase inhibitor compounds and compositions useful in the treatment or prevention of disease or disorders such as myeloproliferative diseases, leukemias, and related diseases or conditions. More specifically, the invention relates to nanoparticulate kinase inhibitor compositions, such as nanoparticulate LS 104 compositions having an effective average particle size of less than about 2000 nm. The invention also relates to methods of making and using such nanoparticulate compositions.
  • Leukemias are cancers of the bone marrow and blood. They are characterized by the uncontrolled accumulation of abnormal blood cells. Examples include acute lymphoblastic leukemia (ALL), Chronic Myelogenous Leukemia (CML) and Acute Myelogenous Leukemia (AML). The most common type of leukemia is acute myeloid leukemia (AML) with an estimated 12,000 new cases annually in the United States. AML occurs mostly in adults over the age of 40 and with an average age of occurrence of 65. Cancers such as AML represent an area of high, unmet medical need; current treatments for AML are characterized by poor long-term response rates with fewer than 20 percent of adult patients surviving after diagnosis.
  • ALL acute lymphoblastic leukemia
  • CML Chronic Myelogenous Leukemia
  • AML Acute Myelogenous Leukemia
  • AML acute myeloid leukemia
  • FLT3 Several kinds of mutation have been found in AML; no single one is at fault, and it appears that at least two are required to trigger disease. However, a mutation in the receptor tyrosine kinase FLT3 occurs in about one third of AML patients and carries a particularly poor prognosis. FLT3 conveys a proliferation signal and is normally expressed early in the development of bone marrow stem cells, but in its mutated form, it remains active and helps leukemic cells flourish. Several groups have been working to identify compounds that could inhibit FLT3.
  • CML and some ALLs are chromosomal translocation that occurs between chromosome 22 and chromosome 9, resulting in an altered chromosome 22 which is known as the "Philadelphia chromosome.”
  • Philadelphia chromosome is the result of a portion of chromosome 9 that includes a portion of the Abelson proto-oncogene (AbI), being translocated to chromosome 22.
  • AbI Abelson proto-oncogene
  • the breakpoints on chromosome 9 may vary, the breakpoints on chromosome 22 are relatively clustered.
  • Bcr breakpoint cluster region
  • Bcr- AbI fused gene that results from the translocation.
  • All forms of the fusion protein include a portion of the Abelson protein having tyrosine kinase activity.
  • the tyrosine kinase activity is constitutive in the Bcr-Abl fusion protein; the negative regulators of this activity no longer function in the fusion protein.
  • This constitutive kinase activity has been shown to activate various signal transduction pathways leading to uncontrolled cell growth and division (e.g., by promoting cell proliferation and inhibiting apoptosis).
  • Bcr-Abl may cause undifferentiated blood cells to proliferate massively and fail to mature.
  • Non-CML myeloproliferative diseases such as polycythemia vera (PV), essential thrombocythemia (ET), and chronic idiopathic myelofibrosis (IMF) and as of yet unclassified myeloproliferative diseases (MPD-NC) are characterized by an aberrant increase in blood cells. See e.g., Vainchenker and Constantinescu, Hematology (American Society of Hematology) 195-200 (2005). This increase is generally initiated by a spontaneous mutation in a multipotent hematopoetic stem cell located in the bone marrow. Id.
  • the stem cell Due to the mutation, the stem cell produces far more blood cells of a particular lineage than normal, resulting in the overproduction of cells such as erythroid cells, megakaryocytes, granulocytes and monocytes.
  • Some symptoms common to patients with MPD include enlarged spleen, enlarged liver, elevated white, red and/or platelet cell count, blood clots (thrombosis), weakness, dizziness and headache.
  • Diseases such as PV, ET and IMF may presage leukemia, however the rate of transformation (e.g., to blast crisis) differs with each disease. Id. [0006]
  • the specific gene and concomitant mutation or mutations responsible for many MPDs is not known.
  • J. Biol. 1 a dominant gain of function mutation in the Janus kinase 2 (JAK2) gene, a cytoplasmic, nonreceptor tyrosine kinase, has been identified in a number of MPDs. For example, this mutation has been reported in up to 97% of patients with PV, and in greater than 40% of patients with either ET or IMF. See e.g., Baxter, et al., Lancet 365:1054-1060 (2005); James, et al., Nature 438: 1144-1148 (2005); Zhao, et al., J. Biol.
  • the Janus kinases are a family of tyrosine kinases that play a role in cytokine signaling.
  • JAK2 kinase acts as an intermediary between membrane-bound cytokine receptors such as the erythropoietin receptor (EpoR), and down-stream members of the signal transduction pathway such as STAT5 (Signal Transducers and Activators of Transcription protein 5).
  • EpoR erythropoietin receptor
  • STAT5 Signal Transduction pathway
  • JAK2 is activated when cytokine receptor/ligand complexes phosphorylate the associated JAK2 kinase. Id. JAK2 can then phosphorylate and activate its substrate molecule, for example STAT5, which enters the nucleus and interacts with other regulatory proteins to affect transcription. Id.
  • Treatment of leukemias and myeloproliferative disorders may involve drug therapy (e.g., chemotherapy), bone marrow transplants, radiation therapy, or combinations thereof.
