The present invention provides preparations of MSCs with important therapeutic potential. The MSC cells are non-primary cells with an antigen profile comprising less than about 1.25% CD45+ cells (or less than about 0.75% CD45+), at least about 95% CD105+ cells, and at least about 95% CD166+ cells. Optionally, MSCs of the present preparations are isogenic and can be expanded ex vivo and cryopreserved and thawed, yet maintain a stable and uniform phenotype. Methods are taught here of expanding these MSCs to produce a clinical scale therapeutic preparations and medical uses thereof.

The present invention provides compositions and methods for the treatment of neoplasms, in particular, by targeting of quiescent and proliferating cancers cells with DYRK1 inhibitor in combination with other treatments effective against certain neoplastic conditions, in particular, anti-cancer treatment with a MEK inhibitor or a b-RAF inhibitor, or a KRAS inhibitor.

The present disclosure relates to the field of nanomedicine, in particular for treating cancers. The present disclosure more specifically provides new methods of treating undesirable M2-polarized macrophages and/or inducing M1 macrophage polarization in a subject in need thereof, comprising administering to said subject a therapeutically effective amount of nanoparticles containing metallic elements.

The present disclosure offers therapeutic solutions to cancer patients up to now considered as unable to undergo a standard-of-care treatment involving radiotherapy or at high risk to undergo a standard-of-care treatment involving radiotherapy. The disclosure relates to nanoparticles and/or aggregates of nanoparticles for use in the treatment of cancer in such a patient, wherein the nanoparticles and/or aggregates of nanoparticles preferably comprise more than 30% by weight of at least one chemical element having an atomic number (Z) between 20 and 83. The disclosed treatments involve a step of administering the nanoparticles and/or aggregates of nanoparticles to the patient, and a step of exposing the patient to a total dose of ionizing radiations that is equal to or less than 85% of the total dose delivered in the standard-of-care treatment. The present description also discloses new compositions comprising such nanoparticles and/or aggregates of nanoparticles as well as uses thereof.

Provided are methods relating to compositions that include a CDP-camptothecin or camptothecin derivative conjugate, e.g., CRLX101.

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

The invention relates to a novel use of ultrafine nanoparticles, of use as a diagnostic, therapeutic or theranostic agent, characterized by their mode of administration via the airways. The invention is also directed toward the applications which follow from this novel mode of administration, in particular for imaging the lungs, and the diagnosis or prognosis of pathological pulmonary conditions. In the therapeutic field, the applications envisioned are those of radiosensitizing or radioactive agents for radiotherapy (and optionally curietherapy), or for neutron therapy, or of agents for PDT (photodynamic therapy), in particular for the treatment of lung tumors.

Methods of treating subjects having G4C2 dipeptide repeat expansion in the gene C9ORF72, including subjects having amyotrophic lateral sclerosis or frontotemporal degeneration (ALS/FTD), are provided. Compounds directed at reducing the toxicity of G4C2 dipeptide repeat expansion in the gene C9ORF72 are described.

The present invention relates to a technique for effective intranasal delivery to the brain. More specifically, the present invention is used for diagnosing, preventing or treating central nervous system encephalopathy, neurodegenerative diseases or brain tumor by effectively delivering to the brain a pH-responsive and bioreducible PPA polymer, which can be used as a drug carrier, by means of nasal administration.

Compositions and methods useful for the treatment of hemoglobinopathies and hematological diseases are disclosed herein. The compositions include an actinium-225 labeled anti-CD45 antibody (BC8) formulated as a single patient dose that is wholly deliverable to a patient in a single dose. The actinium-225 labeled anti-CD45 may be administered alone or in combination with additional therapeutic agents, such as other immunotherapeutics or a radiosensitizing agent, or additional therapeutic interventions, such as bone marrow transplant or adoptive cell therapies.
