The present invention relates to the use of masitinib or a pharmaceutically acceptable salt thereof, for the preparation of a medicament for the treatment of dementia of Alzheimers type, at appropriate dosage regimen.


A method for treating patients afflicted with cancer (including hematological malignancies) or viral infections, wherein the patients are under treatment or are to be treated with at least one anticancer or antiviral agent, and in particular (deoxy)nucleotide or (deoxy)nucleoside analog drugs, includes administering at least one small molecule inhibitor/activator (including ATP competitive inhibitors, signal transduction inhibitors/activators, protein kinase inhibitors/activators, and tyrosine kinase inhibitors/activators) in combination with the (deoxy) nucleotide or (deoxy)nucleoside analog, and wherein the small molecule inhibitor/activator is administered in sufficient amount to modulate deoxynucleotide or deoxynucleoside kinase activity (and in particular deoxycytidine kinase activity) to modulate activation of the (deoxy)nucleotide or (deoxy)nucleoside analog in vivo with a subsequent therapeutically beneficial anticancer or antiviral effect. The combined treatments together include a therapeutically effective amount.


A method for treating patients afflicted with cancer, wherein the patients are treated with a compound including tyrosine kinase inhibitor, mast cell inhibitor or c-Kit inhibitor, in particular masitinib, optionally in combination with at least one antineoplastic agent. The tyrosine kinase inhibitor, mast cell inhibitor or c-Kit inhibitor, and the optional at least one antineoplastic agent, are administered in a dosage regimen that includes a therapeutically effective amount. Also described are methods for predicting therapeutic response to the treatment in a given patient and therefore identification of applicable patient subpopulations based upon these predictor factors; sometimes referred to as biomarkers. One method is based upon the clinical marker of pain intensity. Another method is based upon gene expression predictive biomarkers assessed via RNA expression in peripheral blood cell samples collected prior to treatment with the compound, which is also used for treating patients afflicted with pancreatic cancer.

The present invention relates to compounds of formula I or pharmaceutically acceptable salts thereof: wherein R These compounds selectively modulate, regulate, and/or inhibit signal transduction mediated by certain native and/or mutant protein kinases implicated in a variety of human and animal diseases such as cell proliferative, metabolic, allergic, and degenerative disorders. More particularly, these compounds are potent and selective native and/or mutant c-kit inhibitors.


Novel compounds selected from 2-(3-aminoaryl) amino-4-aryl-thiazoles of formula (I) that selectively modulate, regulate, and/or inhibit signal transductions mediated by certain native and/or mutant tyrosine kinases implicated in a variety of human and animal diseases such as cell proliferative metabolic, allergic and degenerative disorders. More particularly, these compounds are potent and selective c-kit inhibitors.
