RADIATION SENSITIZER OF ANTI-CANCER CHEMOTHERAPY SENSITIZER
20200390687 · 2020-12-17 ·

The present invention provides a novel radiosensitizer or anti-cancer chemotherapy sensitizer. In particular, the invention provides a radiosensitizer or anti-cancer chemotherapy sensitizer that can relieve the irritation of an affected area caused by hydrogen peroxide, is safe when injected into a human body, and can delay or reduce the degradation of hydrogen peroxide and thereby can efficiently exert a radiation sensitizing effect and an anti-cancer chemotherapy sensitizing effect. The radiosensitizer or anti-cancer chemotherapy sensitizer comprises a combination of (a) hydrogen peroxide and (b) hyaluronic acid or salt thereof.

SELF-ASSEMBLING VERTEPORFIN AMPHIPHILES (SAVA) FOR LOCAL CANCER THERAPY

The present invention provides compositions comprising Verteporfin and other anticancer compounds linked to a hydrophilic peptide through a degradable linker molecule to allow the anticancer compounds to penetrate tissues via in situ administration. The compounds of the present invention are useful for sensitizing tumor cells to radiotherapy, preventing recurrence of tumors after surgical resection and for treating remaining unremoved cancer cells at the site of the tumor.

Antibody-drug conjugates and uses thereof

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.

Treatment of neoplasia
10849900 · 2020-12-01 · ·

A method of treating cancer in a patient comprising administering to the patient an a systemic chemotherapeutic drug regime in combination with radioactively doped particle, characterised in that the two therapies when introduced into the patient have an improved anticancer effect.

Biomaterials for combined radiotherapy and immunotherapy of cancer

Compositions and methods for the radiological and immunotherapeutic treatment of cancer are provided. Metallic nanoparticles conjugated with an immunoadjuvant are dispersed within a biodegradable polymer matrix that can be implanted in a patient and released gradually. The implant may be configured as, or be a component of, brachytherapy spacers and applicators, or radiotherapy fiducial markers. The composition may be combined with marginless radiotherapy, allowing for lower doses of radiation and enhancing the immune response against cancer, including at non-irradiated sites.

HYDROGEN PEROXIDE SOLUTION-PREFILLED SYRINGE WITH EXCELLENT HYDROGEN PEROXIDE PRESERVATION DUE TO SILICONE OIL INCLUDED IN OIL COMPOSITION
20200345938 · 2020-11-05 · ·

A syringe that suppresses decomposition of hydrogen peroxide is provided. An object of the present invention is to provide a pre-filled syringe having at least a barrel thereof made of a material having high decomposition capability with respect to hydrogen peroxide, including: a hydrogen peroxide solution therein; and an oil composition applied to an inner wall of the barrel, the oil composition containing silicone oil.

COMPOSITIONS AND METHODS FOR INDUCING NANOPARTICLE-MEDIATED MICROVASCULAR EMBOLIZATION FOR TUMORS
20200338361 · 2020-10-29 ·

Nanoparticle mediated microvascular embolization (NME) of tumor tissue may occur after systemic administration of PEM, leading to widespread shutdown of vascular flow, hemorrhage, and necrosis. PEM constructs are developed that incorporate large amounts of iron-containing protein, possess high oxygen affinities, and demonstrate delayed nitric oxide binding. Such properties induce selective NME of tumors after extravasation, and will likely enhance the effect of VEGFR TKIs and/or mTOR inhibitors.
