  • Publication number: 20230123784
    Abstract: The present invention relates to biodegradable polyethylene glycol based water-insoluble hydrogels comprising backbone moieties which are interconnected by hydrolytically degradable bonds, the backbone moieties further comprising reactive functional groups, wherein the water-insoluble hydrogel is further characterized in that the ratio between the time period for the complete degradation of the hydrogel by hydrolysis of the degradable bonds into water-soluble degradation products comprising one or more backbone moieties and the time period for the release of the first 10 mol-% of water-soluble degradation products comprising one or more backbone moieties based on the total amount of backbone moieties in the hydrogel is greater than 1 and equal to or less than 2. The invention further relates to conjugates of such hydrogels with ligands or ligating groups, prodrugs and pharmaceutical compositions as well as their use in a medicament.

  • Publication number: 20190110514
    Abstract: The invention provides a kit comprising a satiety inducing component A, useful for the treatment and/or prevention of obesity; and a component B complementing component A. Component A comprises a first ingestible solid formulation of a lipid material and a water-swellable or water-soluble polymer, said first ingestible solid formulation being provided in form of ingestible particles that may be used as a partial or full meal replacement. Component B complements component A in that it provides e.g. specific nutrients such as unsaturated fatty acids, vitamins, proteins, amino acids, micro-nutrients, dietary elements, dietary fibres or combinations thereof to a human subject in order to reduce the risk of any deficiencies thereof during a dieting schedule. These nutrients in component B may be provided in an oil, a granulate and/or a powder or powder blend.
