20210315993 · 2021-10-14 ·

The present invention relates to a composition comprising a photosensitizer use in prevention or treatment of dermatological disease in a patient, wherein the composition is used in the following order of steps: (a) topical application or subcutaneous injection of said composition to an area of the skin of said patient, (b) exposure of at least said area of the skin to light with a wavelength spectrum similar or identical to sun light for a duration of 30 min to 5 hours, and (c) exposure of at least said area of the skin to light of a wavelength spectrum comprising only one maximum in the absorbance spectrum of said photosensitizer
as well as to methods of treating dermatological disease using the outlined steps and kits of parts comprising such compositions and light sources suitable to apply the respectively indicated light.

Methods for photodynamic therapy

A method of enhancing penetration of a topical composition of 5-aminolevulinic acid (ALA) into tissue for photodynamic therapy includes topically applying ALA to a treatment area to be treated with photodynamic therapy. The method further includes, after the ALA is applied to the treatment area, covering the treatment area with a low density polyethylene barrier. The treatment area is covered with the low density polyethylene barrier prior to light treatment to minimize transepidermal water loss from the treatment area.

METHODS OF TREATING TUMORS WITH PRO DRUGS
20210369843 · 2021-12-02 ·

Methods of treating tumors by administering compounds to a patient are provided. Compounds such as pro drugs, e.g., 5-aminolevulinic acid (5-ALA), may be administered to the patient orally, by injection, intravenously, or topically, which then accumulate preferentially as compounds such as protoporphyrin IX (PpIX) in tumor cells. After such accumulation, compounds such as PpIX are then activated in various aspects to treat tumors cells, thereby treating cancer. Cancers such as glioblastoma may be treated.

METHODS OF USING PLANAR ACOUSTIC WAVES FOR NON-INVASIVE SONODYNAMIC THERAPY
20210370102 · 2021-12-02 ·

Disclosed are methods of using planar acoustic waves for providing non-invasive sonodynamic therapy. The method includes acoustically coupling an array of flat piezoelectric transducers to a patient. A controller is configured to generate an electrical drive signal at a frequency selected from a range of frequencies, modulate the drive signal, and drive the transducer with the modulated drive signal at the frequency to produce a modulated planar acoustic wave to produce an average acoustic intensity sufficient to activate a sonosensitizer in a treatment region without damaging healthy cells in the treatment region.

Specific photoimmuno-theranostics for detection and elimination of skin cancer cells

The technology provided herein generally relates to novel specific photoimmuno-theranostics for the use in detection and elimination of skin cancer cells. The technology also relates to novel methods which generate homogeneous and specific photoimmuno-theranostics reagents in a simple, controlled and efficient way. This method combines molecular optical imaging, photodynamic therapy and immunotherapy using SNAP-tag technology.

TARGETED COMBINATION THERAPY

Some embodiments of the present disclosure are directed to methods and compositions for the treatment of tumors, using a combination of immunotherapeutic agents and tumor-targeting viral capsid protein assemblages comprising anti-cancer molecules conjugated to viral capsid proteins.

Treatment intervals for use of compositions comprising energy absorbing materials for dermatological applications

The present invention provides compositions comprising energy (e.g., light) absorbing submicron particles (e.g., nanoparticles comprising a silica core and a gold shell) and methods for delivering such particles via topical application. This delivery is facilitated by application of mechanical agitation (e.g. massage), acoustic vibration in the range of 10 Hz-20 kHz, ultrasound, alternating suction and pressure, and microjets. The method of treatment is performed and then, depending upon the desired clinical outcome, repeated after a treatment response interval has elapsed.

Using alternating electric fields to increase cell membrane permeability

Certain substances (e.g., large molecules) that ordinarily cannot traverse the cell membrane of cells can be introduced into cells by applying an alternating electric field to the cell for a period of time, wherein the frequency of the alternating electric field is selected so that application of the alternating electric field increases permeability of the cell membrane. Once the permeability of the cell membrane has been increased, the substance is able to cross the cell membrane. This approach is particularly useful in the context of cancer cells (e.g., glioblastoma).
