Definitions

  • the present invention relates to a water-insoluble controlled-release tyrosine kinase inhibitor (“TKi”) compound for use in the treatment of a cell-proliferation disorder, wherein said water-insoluble controlled-release TKI compound releases one or more TKI drug, wherein the water-insoluble controlled-release TKI compound is administered by intra-tissue administration and wherein the total amount of TKI moieties and TKI drug molecules remaining locally in such tissue 3 days after said intra-tissue administration is at least 25% of the amount of TKI moieties or TKI drug molecules administered by said intra-tissue administration; and to related aspects.
  • TKi water-insoluble controlled-release tyrosine kinase inhibitor
  • Tyrosine kinases are a sub-class of protein kinases that mediate transfer of a phosphate group from adenosine triphosphate (ATP) to specific tyrosine residues of target proteins. This protein phosphorylation serves to modulate protein activity and protein signaling involved in processes such as cell proliferation, differentiation, migration, function, or metabolism.
  • Two types of TKs exist - non-receptor tyrosine kinases (NRTKs) and receptor tyrosine kinases (RTKs).
  • NRTKs are intracellular TKs that propagate signaling cascades induced by RTKs or by other cell surface receptors (e.g. immune cell-associated receptors or G protein-coupled receptors).
  • RTKs are transmembrane glycoproteins that bind extracellular ligands (e.g. VEGF, FGF, EGF, PDGF). Following ligand binding, they become activated, and either auto- phosphorylate tyrosine residues on their intracellular domains or phosphorylate intracellular protein substrates (Hubbard and Hill. Annu Rev Biochem. 2000; 69:373-98).
  • extracellular ligands e.g. VEGF, FGF, EGF, PDGF.
  • Tyrosine kinases regulate many different signaling pathways depending on the cell type and have been implicated in several disease indications, which make them widely pursued for therapeutic purposes.
  • vascular endothelial growth factor (VEGF) receptors VEGFRs
  • VEGF vascular endothelial growth factor receptors
  • VEGFRs vascular endothelial growth factor receptors
  • Aberrant expression of VEGF in the tumor environment may promote tumor vascularization via VEGFR signaling.
  • Inhibition of the VEGFR pathway via small molecule tyrosine kinase inhibitors (TKIs) or biologic antagonists, has been successfully evaluated in preclinical and clinical studies for anti-cancer effects (Takahashi. Biol Pharm Bui. 2011;34(12): 1785-8).
  • TKIs small molecule tyrosine kinase inhibitors
  • Small molecule TKIs have typically been orally administered while biologic tyrosine kinase antagonists are administered intravenously, leading to systemic exposure of the inhibitor/antagonist.
  • efficacy, toxicity, bioavailability and other pharmacokinetic parameters vary greatly depending on the route of administration, systemic inhibition of tyrosine kinases can lead to adverse events, thus limiting their tolerability.
  • VEGFR inhibition is associated with dose limiting hypertension which can lead to sub-optimal drug exposure for cancer treatment (Agarwal et al. Curr Oncol Rep. 2018 Jun 21;20(8):65. doi: 10.1007/sl 1912-018-0708-8).
  • TKIs or TK antagonists may be related to a failure of delivering the drug to the proposed site of action at efficacious concentrations.
  • drug distribution following systemic administration may only serve to exacerbate global side effects due to undesirable systemic exposure to active drug while limiting bioavailability of the active compound in the tumor environment, thus precluding robust anti-tumor benefit. This may be particularly true for small molecule TKIs, which often have broad kinase inhibiting activity, thus affecting multiple kinase pathways (Agarwal et al. Curr Oncol Rep. 2018 Jun 21;20(8):65. doi: 10.1007/sl 1912-018-0708-8).
  • TKIs and biologic tyrosine kinase antagonists that have better specificity for their intended target
  • TKI or biologic tyrosine kinase antagonist treatment regimens such that they overcome the shortcomings of prior art compounds and their related treatment methodologies whilst also providing a favorable anti-tumoral response and reducing adverse events related to systemic exposure.
  • TKI water-insoluble controlled-release tyrosine kinase inhibitor
  • the present invention relates to a water-insoluble controlled-release TKI compound for use in the treatment of a cell-proliferation disorder, wherein said water- insoluble controlled-release TKI compound releases one or more TKI drug, wherein the water-insoluble controlled-release TKI compound is administered by intra-tissue administration and wherein the maximum systemic molar concentration in plasma of TKI drug released from the water-insoluble controlled-release TKI compound within 24 hours after said intra-tissue administration is at least 50% lower than the maximum systemic molar concentration in plasma of TKI drug within 24 hours after intra-tissue administration of an equimolar dose of the corresponding free TKI drug.
  • the present invention relates to a water-insoluble controlled-release TKI compound for use in the treatment of a cell-proliferation disorder, wherein said water- insoluble controlled-release TKI compound releases one or more TKI drug, wherein intra tissue administration of a dose of water-insoluble controlled-release TKI compound that results in anti-tumor activity 7 to 21 days post administration leads to a maximum systemic concentration of TKI drug measured in plasma within 24 hours after said intra-tissue administration that is less than 50% than the maximum systemic concentrations of TKI drug measured in plasma within 24h following systemic administration of a dose of the corresponding free TKI drug required to achieve the same level of anti-tumor activity 7 to 21 days post administration.
  • the water-insoluble controlled-release TKI compounds of the present invention result in high local and low systemic TKI drug concentrations that provide an improved treatment option for cell-proliferation disorders with a reduced risk of side- effects, such as hypertension.
  • Such lower systemic exposure allows for more aggressive multi-agent therapies, facilitates treatment with otherwise poorly tolerated drug combinations and enables treatment of also hard-to-inject tumors that cannot be injected frequently enough with the corresponding free drug molecules.
  • tyrosine kinase inhibitor refers to a molecule that binds to and inhibits one or more cell-associated receptor or non-receptor tyrosine kinases that are activated via polypeptide growth factors, cytokines, hormones, or phosphorylation, and are involved in cellular signaling, cellular development, cellular proliferation, cellular maturation, cellular metabolism, angiogenesis, and in certain instances, tumorigenesis. Tyrosine kinases are ubiquitously expressed by virtually all cells.
  • TKIs inhibit activation of tyrosine kinases by multiple mechanisms such as competing with, or allosterically antagonizing, binding of adenosine triphosphate (ATP) to the tyrosine kinase ATP-binding site, or by inhibiting enzymatic phosphorylation of said binding site, or inhibiting enzymatic kinase activity.
  • ATP adenosine triphosphate
  • receptor TKIs may bind one or more RTKs and inhibit RTK activation as described above or by antagonizing activating ligand interactions, thus preventing receptor tyrosine kinase activation.
  • controlled-release tyrosine kinase inhibitor compound or “controlled-release TKI compound” refers to any matrix with embedded TKI drug or TKI conjugates that comprise at least one TKI moiety and from which at least one TKI drug is released with an in vitro release half-life under physiological conditions (aqueous buffer, pH 7.4, 37°C) of at least 2 days, such as of at least 3 days, at least 7 days, at least 10 days, at least 14 days, at least 21 days, at least one month or at least two months.
  • the maximal release half-life under physiological conditions is 3 months.
  • PRRA pattern recognition receptor agonist
  • PRRA refers to a molecule that binds to and activates one or more immune cell-associated receptor that recognizes pathogen-associated molecular patterns (PAMPs) or damage-associated molecular patterns (DAMPs), leading to immune cell activation and/or pathogen- or damage-induced inflammatory responses.

  • immune checkpoint inhibitor and“immune checkpoint antagonist” are used synonymously and refer to compounds that interfere with the function of, or inhibit binding of ligands that induce signaling through, cell-membrane expressed receptors that inhibit immune cell function upon receptor activation.
  • Such compounds may for example be biologies, such as antibodies, nanobodies, probodies, anticalins or cyclic peptides, or small molecule inhibitors.

  • the term“antibody-drug conjugate” refers to compounds typically consisting of an antibody linked to a biologically active cytotoxic payload, radiotherapy, or other drug designed to deliver cytotoxic agents to the tumor environment. ADCs are particularly effective for reducing tumor burden without significant systemic toxicity and may act to improve the effectiveness of the immune response induced by checkpoint inhibitor antibodies.
  • radionuclides refers to radioactive isotopes that emit ionizing radiation leading to cellular destruction/death. Radionuclides conjugated to tumor targeting carriers are referred to as“targeted radionuclide therapeutics”.
  • DNA damage repair inhibitor refers to a drug that targets DNA damage repair elements, such as for example CHK1, CHK2, ATM, ATR and PARP. Certain cancers are more susceptive to targeting these pathways due to existing mutations, such as BRCA1 mutated patients to PARP inhibitors due to the concept of synthetic lethality.
  • tumor metabolism inhibitor refers to a compound that interferes with the function of one or more enzymes expressed in the tumor environment that produce metabolic intermediates that may inhibit immune cell function.
  • protein kinase inhibitor refers to compounds that inhibit the activity of one or more protein kinases.
