Use of histone deacetylase inhibitors for the care of philadelphia-negative myeloproliferative syndromes
Method of treating Philadelphia-negative myeloproliferative syndromes in a patient suffering from such syndromes. The method is carried out by administering to the patient diethyl-[6-(4-hydroxycarbamoyl-phenylcarbamoyloxymethyl)-naphthalen-2-yl -methyl]-ammonium chloride, or other pharmaceutically acceptable salts and/or solvates, in a daily dosage amount of from 10 to 150 mg per patient.
1. Method of treating Philadelphia-negative myeloproliferative syndromes in a patient suffering from said syndromes, said method comprising administering to said patient diethyl-[6-(4-hydroxycarbamoyl-phenylcarbamoyloxymethyl)-naphthalen-2-yl-methyl]-ammonium chloride, or other pharmaceutically acceptable salts and/or solvates, and at least one other cytostatic active principle, wherein said diethyl-[6-(4-hydroxycarbamoyl-phenylcarbamoyloxymethyl)-naphthalen-2-yl-methyl]-ammonium chloride, or other pharmaceutically acceptable salts and/or solvates thereof is administered in a daily dosage amount of from 50 to 150 mg per patient.
2. Method according to claim 1 , wherein said diethyl-[6-(4-hydroxycarbamoyl-phenylcarbamoyloxymethyl)-naphthalen-2-yl-methyl]-ammonium chloride is in monohydrate form.
