Abstract: The present invention relates to a compound of formula (Ia), or a pharmaceutically acceptable salt or hydrate thereof, wherein: the group X-Y is —NHSO2— or —SO2NH—; R1 is H or alkyl; R2 is selected from COOH and a tetrazolyl group; R3 is selected from H, Cl and alkyl; R4 is selected from H, Cl and F; R5 is selected from H, alkyl, alkynyl, alkenyl, haloalkyl, SO2-alkyl, Cl, alkoxy, OH, CN, hydroxyalkyl, alkylthio, heteroaryl, cycloalkyl, heterocycloalkyl and haloalkoxy; R6 is H; R7 is selected from H, CN, haloalkyl, Cl, F, SO2-alkyl, SO2NR13R14, optionally substituted heteroaryl and alkyl; R8 is selected from H, alkyl, haloalkyl and halo; R9 is H, C1-C3-alkyl, or halo; R10 and R11, together with the nitrogen to which they are attached, form an azepanyl group, wherein (a) said azepanyl group is substituted by one or more substituents, or (b) one or two carbons in said azepanyl group are replaced by a group selected from O, NH, S and CO, and said azepanyl group is optionally further substituted; or R10 and R11,
