USE OF SUBSTITUTED HEXITOLS INCLUDING DIANHYDROGALACTITOL AND ANALOGS TO TREAT NEOPLASTIC DISEASE AND CANCER STEM CELLS INCLUDING GLIOBLASTOMA MULTIFORME AND MEDULLOBLASTOMA
The use of dianhydrogalactitol provides a novel therapeutic modality for the treatment of glioblastoma multiforme and medulloblastoma. Dianhydrogalactitol acts as an alkylating agent on DNA that creates N7 methylation. Dianhydrogalactitol is effective in suppressing the growth of cancer stem cells and is active against tumors that are refractory to temozolomide; the drug acts independently of the MGMT repair mechanism.
Devices, systems, and methods for excavating cancer cells
Methods, devices, and systems are provided for guiding tumor movement, particularly in vivo for treatment of patients. The method may include implanting into a tissue site where tumor cells are present a device having one or more surface structures or substrates, such as aligned nanofibers, which provide physical guidance cues for directing the migration of the tumor cells from the first tissue location to a selected second location, for tumor cell extraction or death. The devices and systems may include a cytotoxic agent for contacting tumor cells migrated via the substrate. All or a portion of the at least one substrate may include one or more biochemical cues, such as a coating of laminin or another protein, which may be provided in a concentration gradient to facilitate uni-directional tumor cell migration.
ANTIVIRAL AGENTS
An antiviral agent is provided, having a phosphorodiamidate morpholino oligomer with an antisense sequence to a portion of a genome of a strain of Zika virus (ZIKV). The antiviral agent finds many uses, such as in a pharmaceutical composition, a method of treating ZIKV-mediated disease, a method of preventing ZIKV-mediated disease, a method of reducing or preventing the replication of ZIKV in a host cell, a method of controlling the spread of ZIKV in donated tissue, a treated tissue sample, and in the manufacture of a medicament for the treatment or prevention or ZIKV-mediated disease.
Compositions of polymeric nanowires and methods of making and using thereof
Aspects of the present disclosure include compositions having a plurality of individual polymeric nanowires. Individual polymeric nanowires according to embodiments include a bioactive compound. Methods for preparing and methods for administering the subject compositions of individual polymeric nanowires to a subject are also described. Kits having one or more components for practicing the subject methods are also provided.
ANTIBODY-DRUG CONJUGATE WITH IMPROVED THERAPEUTIC WINDOW
The invention relates to a therapeutic combination, comprising a first proteinaceous molecule comprising a first binding site for binding to a first epitope of a first cell-surface molecule, the first proteinaceous molecule provided with at least one saponin covalently bound to an amino-acid residue of said first proteinaceous molecule, and comprising a second pharmaceutical composition comprising a second proteinaceous molecule different from the first proteinaceous molecule, the second proteinaceous molecule comprising a second binding site for binding to a second epitope of a second cell-surface molecule different from the first cell-surface molecule, and comprising an effector moiety, wherein the second epitope is different from the first epitope. An aspect of the invention is a composition comprising the first proteinaceous molecule and the second proteinaceous molecule of the invention. The invention also relates to a composition or therapeutic combination comprising an antibody-drug conjugate or antibody-oligonucleotide conjugate and the first proteinaceous molecule of the invention. An aspect of the invention relates to a pharmaceutical composition comprising the composition or the antibody-drug conjugate of the invention, and optionally further comprising a pharmaceutically acceptable excipient. The invention also relates to the therapeutic combination or the composition or the antibody-drug conjugate or the pharmaceutical composition of the invention, for use as a medicament. The invention also relates to the therapeutic combination of the invention for use in the treatment or prophylaxis of a cancer.
STEREOCOMPLEXES FOR THE DELIVERY OF ANTI-CANCER AGENTS
Disclosed herein are stereocomplexes for the delivery of one or more anti-cancer agents. The stereocomplexes exhibit low toxicity and are biodegradable while also providing for controlled release of one or more anti-cancer agents at tumor sites. The stereocomplexes can be designed such that the anti-cancer agents operate synergistically and may optionally include additional targeting groups and functionalities. The stereocomplexes disclosed herein can be combined with pharmaceutically-acceptable carriers and/or excipients to form pharmaceutical compositions. By varying the amount of each anti-cancer agent in the stereocomplex, specific types of tumors and cancer cell lines can be treated.
BIOLOGICALLY ACTIVE CLUSTER OF MOLECULES
The invention relates to a molecular scaffold suitable for covalently binding at least one biologically active molecule to a carrier molecule, the scaffold comprising a polymeric structure and the biologically active molecules covalently bound to said polymeric structure, and wherein the scaffold further comprises a chemical group for covalently coupling of the scaffold to the carrier molecule. The biologically active molecule has a molecular weight of 3.000 Dalton or less, such as 1.700 Dalton-1.950 Dalton. The biologically active molecule is an amphiphilic molecule in some embodiments. The biologically active molecule is a single specific molecule or is a mixture of different types of molecules, when more than one biologically active molecules are covalently bound to the polymeric (or oligomeric) structure. In particular, the invention relates to monoclonal antibody-based antibody-drug conjugates with improved therapeutic window of the drug due to covalent linkage of (a cluster of) potentiator molecules, e.g. a payload such as a protein toxin or oligonucleotide to the ADC, or alternatively, due to co-administration of an ADC and a cell-targeting conjugate comprising (a cluster of) potentiator molecules to a patient in need thereof. The invention also relates to a method for producing a scaffold suitable for covalently binding a biologically active molecule to a carrier molecule, providing a cluster of potentiator molecules.
