The present invention relates to immune stimulating micelle compositions, and their use in treatment of diseases and disorders, such as cancer. In particular, the present invention relates to micelle compositions comprising a TLR7 agonist, such as 1V270.

Immune stimulating micelle composition

The present invention provides liposomes that are useful for delivery of bioactive agents such as therapeutics. Among others, the liposomes of the invention are capable of delivering their payload at sites of increased secretory phospholipase A2 (sPLA2) activity, because phospholipase A2 (PLA2) will hydrolyse lipids of the liposome. Thus, the liposomes of the invention may e.g. be used in relation to cancer therapy. Another aspect of the invention is a liposomal formulation comprising the liposome of the invention. Still another aspect is a method of producing a liposomal formulation of the invention.

Liposomes for drug delivery and methods for preparation thereof

The present invention is directed to the technical field of imaging compositions useful for diagnosing cancer and other diseases in a subject. In particular, the invention relates to a class of diagnostic compounds comprising a novel liposome composition with encapsulated metal entities such as radionuclides, for exampleCu andCu copper isotopes. The invention further relates to a novel method for loading delivery systems, such as liposome compositions, with metal entities such as radionuclides, and the use of liposomes for targeted diagnosis and treatment of a target site, such as cancerous tissue and, in general, pathological conditions associated with leaky blood vessels. The present invention provides a new diagnostic tool for the utilization of positron emission tomography (PET) imaging technique.

Entrapment of radionuclides in nanoparticle compositions

The present application discloses a nanoparticle comprising compounds of the formula A-B-C(-D), wherein A designates an anchoring moiety having self-organizing properties in relation to the nanoparticle; B designates a cleavable linker; C designates an anionic moiety having a net charge of at least &#x2212;2 at pH 6.0; and D, which is optional, designates a polymer moiety which induces long circulating properties of the nanoparticle in mammalian tissue; and wherein the average net charge of the compounds is at least &#x2212;1 at pH 6.0. The application also discloses the individual compounds of the formula A-B-C(-D) as well as a drug delivery system comprising the self-organized nanoparticle having included in the interior thereof one or more pharmaceutically active agents and/or diagnostically relevant species, and a method of treating a cancerous or inflammatory condition in a mammal, involving the administration of the drug delivery system to the mammal.

Charge triggering of self-organized nanoparticles

The present invention relates to a novel composition and method for loading delivery systems such as liposome compositions with radionuclides useful in targeted diagnostic and/or therapy of target site, such as cancerous tissue and, in general, pathological conditions associated with leaky blood vessels. The composition and methods of the invention find particular use in diagnosing and imaging cancerous tissue and, in general, pathological conditions associated with leaky blood vessels in a subject. The present invention provides a new diagnostic tool for the utilization of positron emission tomography (PET) imaging technique. One specific aspect of the invention is directed to a method of producing nanoparticles with desired targeting properties for diagnostic and/or radio-therapeutic applications.
