The present invention relates among other aspects to a conjugate or a pharmaceutically acceptable salt thereof or a pharmaceutical composition comprising said conjugate or its pharmaceutically acceptable salt for use in a method of preventing or treating an infection, wherein said conjugate is water-insoluble and comprises a polymeric moiety —Z to which a plurality of moieties -L2-X0D-L1-D are covalently conjugated, wherein each -D is independently an antibiotic moiety; each -L1- is independently a linker moiety to which -D is covalently and reversibly conjugated; each —X0D— is independently absent or a linkage and each -L2- is independently either a chemical bond or a spacer moiety.
A conjugate or a pharmaceutically acceptable salt thereof or a pharmaceutical composition comprising said conjugate or its pharmaceutically acceptable salt for use in a method of preventing or treating an infection, wherein said conjugate is water-insoluble and comprises a polymeric moiety —Z to which a plurality of moieties -L2-X0D-L1-D are covalently conjugated,
A water-insoluble conjugate comprising a plurality of antibiotic moieties -D covalently and reversibly bound to a polymeric moiety, wherein the antibiotic moieties are released from the polymeric moiety and wherein a single intra-articular injection provides a concentration of said antibiotic in the intra-articular compartment of at least 1 μg antibiotic/ml synovial fluid for at least 3 days.
A sustained-release compound or a pharmaceutically acceptable salt thereof or a pharmaceutical composition comprising said compound or its pharmaceutically acceptable salt comprising a plurality of antibiotic moieties -D or antibiotic molecules D-H or D-OH, wherein the antibiotic moieties or molecules are released from said sustained-release compound and provide a concentration in the intra-articular compartment of said antibiotic that is at least 1.1-fold above the minimal biofilm eradicating concentration of the respective antibiotic for at least 3 days after a single intra-articular injection.
