  • Patent number: 9034359
    Abstract: The present invention relates to a drug carrier composition comprising i) one or more biodegradable hydrating ceramics ii) one or more expandable agents, and iii) sorbed aqueous medium which in solid form has a ruptured structure. The function of the expandable agent is to create a ruptured structure in the solidified composition, either a foam-like structure or a disintegrated structure where it is split into a large number of parts, particles, units, granules or pieces, so as to obtain an enlarged apparent surface area that is exposed to degradation or erosion upon administration. Suitable substances to obtain this surface enlarging effect are gas-forming agents or swelling agents, gelling agents or disintegrants, here referred to as expandable agents. The expandable agents may be bioresorbable or non-bioresorbable.

  • Patent number: 8999389
    Abstract: A novel method for the preparation of a highly densified and at least partly, preferably fully or almost fully hydrated ceramic for use in the preparation of a pharmaceutical composition notably for controlled-release of one or more therapeutically, prophylactically and/or diagnostically active substance. The method involves a concomitant step of hydrating and densifying a bioresorbable and hydratable ceramic such as calcium sulphate. The invention also relates to compositions comprising such a highly densified ceramic. The pharmaceutical composition is useful for targeted and controlled local prolonged release of active substances, e.g. anti-cancer agents, whereby the spectrum and severity of side effects are minimized due to an optimized local concentration-time profile.

  • Patent number: 8936809
    Abstract: A method for treating prostate related diseases in a subject, the method comprising i) optionally administering to subject an initial boost dose of one or more active substances and/or prodrugs, and ii) administering locally into the prostate a controlled release pharmaceutical composition comprising one or more active substances in a biodegradable ceramic carrier. The biodegradable hydrating ceramic may be selected from the group consisting of non-hydrated or hydrated calcium sulphate, calcium phosphate, calcium carbonate, calcium fluoride, calcium silicate, magnesium sulphate, magnesium phosphate, magnesium carbonate, magnesium fluoride, magnesium silicate, barium sulphate, barium phosphate, barium carbonate, barium fluoride, barium silicate, or mixtures thereof. In a specific embodiment, the biodegradable hydrating ceramic is non-hydrated or hydrated calcium sulphate.

  • Patent number: 8556495
    Abstract: An injector device is disclosed, the injector device comprising an elongated mixing container extending along a first axis, and a piston member slidably positioned in the mixing container. The injector device comprises a mixing device comprising a mixing member, an elongated member parallel to the first axis and a handle member. The piston member comprises a piston head and a first locking arm flexibly connected to the piston head, such that the first locking arm in a first position extends substantially parallel to the elongated member and engages with the mixing device in such a way that the piston member moves in a first direction along the first axis with the mixing device. In a second position, the first locking arm may allow the mixing device to move relative to the mixing container independently of the piston member.
