Cancer Imaging Methods And Cancer Treatment Methods Using Thermotherapy And Drug Delivery

Cancer imaging methods and cancer treatment methods using thermotherapy and drug delivery are disclosed herein. In one embodiment, the temperature of heated tissue is determined from radio-frequency data from an ultrasound transducer based upon a change in backscattered energy of acoustic harmonics. In another embodiment, a plurality of nanocarriers containing an anti-tumor medication are administered to a patient, and are excited in a first non-thermal ultrasound mode and/or a second thermal ultrasound mode using an ultrasound source. In yet another embodiment, a plurality of nanoparticles are administered to a patient, then at least some of the nanoparticles are heated along with tissue at a site of a tumor, and a photoacoustic imaging unit is used to determine a temperature of the heated tissue at the site of the tumor.

THERAPY

The invention generally relates to sonodynamic therapy using microbubble-sonosensitiser complexes and, more specifically, to such therapy for the treatment of deeply-sited tumours and associated metastatic disease. In particular, the invention relates to a combination therapy in which sonodynamic treatment of deeply-sited tumours with microbubble-sonosensitiser complexes is combined with treatment using immune checkpoint inhibitors. It further relates to methods of sonodynamic therapy in which a sonodynamic-induced abscopal response modulates a systemic regression of metastatic disease. In such methods the abscopal response may be further enhanced by co-administration of an immune checkpoint inhibitor. The invention is particularly suitable for the treatment of pancreatic cancer (e.g. pancreatic ductal adenocarcinoma) and associated metastasis.

METHODS OF TREATING TUMORS WITH PRO DRUGS

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.

New advantageous compositions and methods for treatment of malignancies such as basel cell carcinoma and other skin cancers, brain tumors, head and neck cancer, kidney cancer, prostate cancer and other cancer types. The new compositions and methods may also be used for treatment of non-cancer problems such as dermatological diseases, sexual diseases, anti-fungal and antibacterial and wound healing. A new photodynamic therapy/sonodynamic therapy (PDT/SDT) combination approach using near infrared (NIR) tetrapyrrolic photosensitizers (PSs) with long wavelength absorption, in the range of 750-800 nm, that provides deeper tissue penetration. Such combinations may be postloaded onto PAA nanoparticles (NPs) for better delivery to a tumor site. A preferred sonodynamic compound is fullerene 60 but other sonodynamic compounds may be employed. The unique NP formulations of the invention can contain chemotherapeutic agents releasable by ultrasound in cancer or other hyperproliferative tissue. NP formulations may also contain tumor targeting moieties.
