The invention relates to a DGAT inhibitor of formula (I), including any stereochemically isomeric form thereof, wherein A represents CH or N; the dotted line represents an optional bond in case A represents a carbon atom; X represents —O—C(═O)—; —C(═O)—C(═O)—; —NRX—C(═O)—; —Z—C(═O)—; —Z—NRX—C(═O)—; —C(═O)—Z—; —NRX—C(═O)—Z—; —C(═S)—; —NRX—C(═S)—; —Z—C(═S)—; —Z—NRX—C(═S)—; —C(═S)—Z—; —NRX—C(═S)—Z—; Z represents a bivalent radical selected from C1-6alkanediyl, C2-6alkenediyl or C2-6alkynediyl; wherein each of said C1-6alkanediyl, C2-6alkenediyl or C2-6alkynediyl may optionally be substituted; and wherein two hydrogen atoms attached to the same carbon atom in C1-6alkanediyl may optionally be replaced by C1-6alkanediyl; Y represents —C(═O)—NRX— or —NRX—C(═O)—; R1 represents adamantanyl, C3-6cycloalkyl; aryl1 or Het1; R2 represents C3-6cycloalkyl, phenyl, naphtalenyl, 2,3-dihydro-1,4-benzodioxinyl, 1,3-benzodioxolyl, 2,3-dihydrobenzofuranyl or a 6-membered aromatic heterocycle containing 1 or 2 N atoms, wherein said C3-6Cycloalkyl, phenyl, naphtalenyl, 2,3-dihydro-1,4-benzodioxinyl, 1,3-benzodioxolyl or heterocycle may optionally be substituted; R7 represents hydrogen, halo, C1-4alkyl, C1-4alkyl substituted with hydroxyl; provided that the following compounds (II), (III) are excluded; a N-oxide thereof, a pharmaceutically acceptable salt thereof or a solvate thereof. The invention further relates to methods for preparing such compounds, pharmaceutical compositions comprising said compounds as well as the use as a medicine, as a DGAT inhibitor, of said compounds.
