Nanoparticles having radially-oriented pores are fabricated from a noble metal. The pores have a specific geometrical shape, such as a circle, triangle, hexagon or other polygon. The nanoparticles are administered to a subject to form a nanoparticle-loaded tumor, which is targeted with a radiation beam as part of a radiotherapeutic treatment. The pores redirect photons of the radiation beam to intensify and enhance the dose received by tumor cells, while concomitantly reducing the dose received by surrounding cells and/or tissues. The nanoparticles may be combined with a radiosensitizing drug or agent, administered together or separately, to form a dose-enhancement composition that further intensifies the received dose of radiation at the target.

Provided herein are nanoparticle compositions (e.g., nanoparticle compositions comprising high atomic number ions) that are useful for imaging diseases in a subject as well as radiosensitizing a disease in a subject (e.g., radiosensitizing a cancer in the subject). Methods of imaging a subject, methods of treating cancer, and processes of preparing the nanoparticle compositions are also provided.

The invention provides methods and compositions for treatment of a subject with a glioma. The methods comprise administering a composition comprising Coenzyme Q10 to the subject by continuous intravenous infusion; and administering radiation therapy to the subject. The composition comprising Coenzyme Q10 may be administered to the subject by continuous intravenous infusion for at least 24 hours before the radiation therapy is initiated.

CD47+ disease cells such as cancer cells are treated using a combination of CD47 blocking agent and poly-(ADP-ribose) polymerase (PARP) inhibitor. The CD47 blocking agent can be SIRPαFc and the PARP inhibitor niraparib. The anti-cancer effect of niraparib is enhanced in the presence of SIRPαFc. Specific combinations include SIRPαFc forms that comprise an Fc that is either IgG1 or preferably IgG4 isotype. These combinations are useful particularly to treat solid tumours and blood cancers including lymphomas, leukemias and myelomas.

The present document describes methods of use of photo activated compositions for oral disinfection and/or treatments which comprise at least one oxidant, at least one photoactivator capable of activating the oxidant, and at least one healing factor chosen from hyaluronic acid, glucosamine and allantoin, in association with a pharmacologically acceptable carrier.

The present application relates to activable inorganic nanoparticles which can be used in the health sector, in particular in human health, to disturb, alter or destroy target cancerous cells, tissues or organs. It more particularly relates to nanoparticles which can generate a surprisingly efficient therapeutic effect, when concentrated inside the tumor and exposed to ionizing radiations. The invention also relates to pharmaceutical compositions comprising a population of nanoparticles as defined previously, as well as to their uses.

A fluorocarbon emulsion in water for use in fractionated radiotherapy and chemotherapy, wherein said fluorocarbon comprises between 4 and 8 carbon atoms.

The present invention relates to therapeutic immunoconjugates comprising SN-38 attached to an antibody or antigen-binding antibody fragment. The antibody may bind to Trop-2 or CEACAM5 and the immunoconjugate may be administered at a dosage of between 4 mg/kg and 16 mg/kg, preferably 4, 6, 8, 9, 10, 12, or 16 mg/kg. When administered at specified dosages and schedules, the immunoconjugate can reduce solid tumors in size, reduce or eliminate metastases and is effective to treat cancers resistant to standard therapies, such as radiation therapy, chemotherapy or immunotherapy. Surprisingly, the immunoconjugate is effective to treat cancers that are refractory to or relapsed from irinotecan.

Materials and methods for enhancing the effectiveness of proton radiation therapy (e.g., high linear energy transfer (LET) proton radiation therapy) against tumor cells are provided herein.

The present invention relates to the field of human health and more particularly concerns nanoparticles for use as a therapeutic vaccine in the context of radiotherapy in a subject suffering of a cancer, in particular of a metastatic cancer or of a liquid cancer.
