The invention concerns tricyclic -heteroaryl-carboxamidederivatives containing a benzimidazole unit, of general formula (I) wherein:A represents, with the C-N bond of the benzimidazole unit to which it is bound,a 4- to 7-membered monocyclic heterocycle or a monocyclic heteroaryl containingfrom one to three heteroatoms selected among O, S or N, including the nitrogenatom of the benzimidazole unit; P represents a 8-, 9-, 10-, 11-membered bicyclicheterocycle or a bicyclic heteroaryl, comprising 1 to 6 heteroatoms selectedamong N, O or S; R represents on to four atoms or groups, identical ordifferent; Y represents an oxygen or sulfur atom; R represents a hydrogenatom, a halogen atom, a CC-alkyl, C-C-cycloalkyl, C-C-cycloalkyl-C-C-alkylene,CC-fluoroalkyl or CC-alkoxygroup; R represents from one to three atoms or groups, identical ordifferent; in base or acid addition salt state as well as in hydrate or solvateform. The invention also concerns a method for preparing the compounds and theirtherapeutic use.
