Description

[Technical Field]

[0001] Field The disclosure provided herein relates generally to medical procedures. More particularly, the disclosure relates to medical procedures using ultrasound and ultrasound sensitizers. [Background technology]

[0002] background Hematoporphyrin and its derivatives were described in 1942 as preferentially accumulating in tumor cells (H. Auler et al., Z. Krebsforsch. (1942) 53:65-68). The fluorescent properties of the compounds are used to identify tumor tissue as surgical aids and diagnostics (R. Vanseviciute et al., Medicina (2014) 50:137-43; J. Zhang et al., Acta Pharm Sinica B (2018) 8:137-46). In 1972, it was demonstrated that hematoporphyrin could be used to selectively sensitize tumor cells to light in the presence of oxygen (the "photodynamic effect"), leading to tumor size reduction, a procedure now known as photodynamic therapy (I. Diamond et al., Lancet (1972) 2:1175-77). In most organisms, hematoporphyrin is converted to heme and related molecules. Hematoporphyrin is thought to accumulate in certain tumor tissues due to iron deficiency or dysfunction of metabolic enzymes (W. Song et al., Anticancer Res (2011) 31:39-46; C.J. Gomer et al., Cancer Res (1979) 39:146-51). This allows for the selective destruction of tumor cells using light, leaving healthy adjacent tissue relatively unaffected. It has been found that when exogenous 5-aminolevulinic acid ("5-ALA") is administered, the photosensitizing porphyrin, protoporphyrin IX, the first molecule involved in the heme pathway, accumulates, enabling tissue photosensitization within one hour (C. Perotti et al., Br J Cancer (2004) 90:1660-65). However, photodynamic therapy is limited by tissue opacity: effectively treating tumors that are not accessible from the body surface or lumen requires surgical access to the tumor site.

[0003] Sonodynamic therapy (SDT) is a method of cell destruction using focused ultrasound (FUS) after sensitization with an ultrasound sensitizer. The mechanism of action has not been conclusively determined but is thought to result from singlet oxygen produced by thermal effects and / or cavitation. Ultrasound can penetrate tissue much farther than light, making noninvasive treatments available to more of the body. Surprisingly, protoporphyrin IX was also discovered to be an effective ultrasound sensitizer (N. Yumita et al., Jpn J Cancer Res (1989) 80(3):219-22), enabling ultrasound-mediated cell destruction under otherwise ineffective conditions. While the mechanism of action is unclear, it has been hypothesized to result from singlet oxygen formation.

[0004] To date, there have been many reported in vitro and in vivo experiments, but no clinical trial results (H. Hirschberg et al., Ther Deliv (2017) 8:331-42). For example, N. Yumita et al. (ibid.) reported that hematoporphyrin (10, 25, or 50 μg / mL) and 1.27, 2.21, or 3.18 W / cm for durations of 15, 30, or 60 seconds were used to treat rheumatoid arthritis. 2 investigated the effects of SDT on mouse sarcoma 180 or rat ascites hepatoma 130 cells in vitro using ultrasound (1.92 MHz) at an intensity of 1.5 W / cm. Hematoporphyrin was applied to the cells 15, 30, or 60 seconds before ultrasound application. Yumita reported that 60 seconds of ultrasound alone damaged a significant number of cells (16% and 17% for sarcoma 180 and ascites hepatoma, respectively) as measured by trypan blue dye exclusion. Higher intensities damaged more cells (2.21 W / cm). 2 : 71% and 75%; 3.18W / cm 2 79% and 86%). When hematoporphyrin was added (50 μg / mL), the 2 or 3.18 W / cm 2 Although the radiation damaged substantially more sarcoma cells (67% and 98%) after exposure to 2.21 and 3.18 W / cm2 At 3.18 W / cm, more AH cells were damaged (95% and 96%). Statistically significant cell damage was also observed at 3.18 W / cm. 2 The use of 25 μg / mL hematoporphyrin with an ultrasound intensity of 10 μg / mL has also been reported (98% and 96%), which was equivalent to cell destruction using 50 μg / mL.

[0005] N. Yumita et al., Cancer Sci (2004) 95:765-69, reported that porfimer sodium (0, 0.5, 1.0, 2.5, or 5 mg / kg, iv 24 hours before ultrasound) was administered with 1, 2, 3, or 5 W / cm 2 reported the treatment of female Sprague Dawley rats bearing mammary tumors (induced by injection of 7,12-dimethylbenz(α)anthracene) with 1.92 MHz ultrasound at an intensity of 1.5 W / cm for 15 minutes. 2 SDT treatment with 1000 W / cm or higher effectively inhibited tumor growth, and higher treatment levels (3 W / cm or higher) 2 5mg / kg or 5W / cm 2 2.5mg / kg) is 3W / cm 2 reported that there was no significant difference between treatment with 2.5 mg / kg and treatment with 2.5 mg / kg.

[0006] W. Song et al. (cited above) reported that the 2Song investigated the response of SAS cells in vitro using 5-ALA (1, 10, or 50 μg / mL) applied 4 hours before 1.05 MHz ultrasound with an intensity of 100 Hz, a pulse repetition frequency of 100 Hz, and a duty cycle of 60% for a duration of 2 minutes. Song reported cell viabilities of 89%, 88%, 75%, and 62% (for 0, 1, 10, and 50 μg / mL 5-ALA); the decrease in viability was statistically significant at 10 and 50 μg / mL. Song also reported that treatment with ultrasound enhanced SAS cell apoptosis, intracellular reactive oxygen species, and lipid peroxidation, and that the addition of 10 μg / mL 5-ALA significantly enhanced these effects.

[0007] S. Suehiro et al., J Neurosurg (2018) 129:1416-28, used a 20% duty cycle for 3 min, 5-ALA (1 mM) and 2 W / cm 2 Ultrasound (3MHz) was used to measure U87 and U251 glioma cells, and U251 Oct-3 / 4 Suehiro reported an in vitro study using glioma stem-like cells, U87 and U251, using ultrasound alone. Oct-3 / 4 reported that ultrasound destroyed tumor cells to a significant extent, but not U251 cells. Ultrasound in combination with 5-ALA (1 mM) was substantially cytotoxic to all tumor cells tested (but not to normal control cells), and was more effective than ultrasound alone in all three cases. Suehiro also reported the combination of 5-ALA (100 mg / kg) and ultrasound (2.2 MHz, 0.5 or 2.0 W / cm), repeated weekly for 3 weeks. 2 Human U87 glioma cells or U251 treated with 1000kJ / cm2 PBS (20% duty cycle for 3 min). Oct-3 / 4 They also used immunodeficient BALB / c nude mice injected with glioma stem-like cells. Suehiro reported that SDT treatment significantly improved survival of the treated mice.

[0008] JY Kou et al., Cell Death Dis (2017) 8:e2558 was administered at an intensity of 0.4 W / cm for a duration of 10 min. 2 reported an in vitro study on human THP-1 monocytes (induced to become macrophages and foam cells) exposed to ultrasound (1.0 MHz) at 30 μg / mL using berberine as an ultrasound sensitizer (other concentrations, intensities, and durations were also tried, but no combinations were). Kou reported that the treatment induced autophagy in macrophages and increased cholesterol efflux.

[0009] M. Nonaka et al., Anticancer Res (2009) 29:943-50 was injected into Wistar rats, and then treated with rose bengal (50 mg / kg, i.v. 10 min before treatment) and ultrasound (25 W / cm 2 C6 rat glioma cells were treated with a 1 MHz transducer (at 1000 kJ / s for 5 min, using a transducer applied directly to the brain surface through a 10 mm craniotomy). Control groups lacking glioma cells were also treated with 0, 10, or 50 mg / kg rose bengal and 25 and 110 W / cm. 2 Nonaka showed that rats with normal brain tissue were exposed to ultrasound at 25W / cm with or without rose bengal. 2 reported that no lesions were observed at 110W / cm 2 Rats with normal brain tissue treated with ultrasound alone for 3 minutes at 110 W / cm showed coagulative necrosis in 2 of 6 rats and in 5 of 6 rats treated for 5 minutes at that intensity. 2 All rats treated with 3 minutes of ultrasound at 110 W / cm showed lesions (5 / 5 for each group). 2 Rats treated with 5 minutes of ultrasound at 10 mg / kg also showed lesions (6 / 7 at 10 mg / kg; 6 / 6 at 50 mg / kg).

[0010] T. Ohmura et al., Anticancer Res (2011) 31:25274-33 were injected into Wistar rats, and 5-ALA (100 mg / kg, orally administered 3 hours before ultrasound treatment) and 10 W / cm using an ultrasound transducer applied directly to the brain surface through a 10 mm craniotomy. 2 C6 rat glioma cells were treated with 1.04 MHz ultrasound for 5 minutes at 10, 15, 20 or 25 W / cm. Rats with normal brain tissue were also treated with 1.04 MHz ultrasound at 10, 15, 20 or 25 W / cm. 2 The patients were also treated with 5 minutes of ultrasound at 15, 20 or 25 W / cm. 2 reported that rats with normal brain tissue that received ultrasound showed necrosis in the ultrasound focal area. Rats with glioma cells treated with SDT showed significantly smaller tumors than rats that received only 5-ALA or ultrasound.

[0011] EJ Jeong et al., Ultrasound Med Biol (2012) 38:2143-50, 5-ALA (60 mg / kg) or Radachlorin (40 mg / kg); and 1.0 MHz, 2.65 W / cm 2 used Sprague Dawley rats inoculated with C6 glioma cells that were treated with 20 minutes of ultrasound (16 minutes of ultrasound, followed by a 3-minute break, followed by another 4 minutes of ultrasound) at 20°C. Jeong reported that rats that underwent SDT exhibited tumors that were significantly smaller in size than the control group.

[0012] Y Li et al., PLoS One (2015) 10:e0132074, treated with 5-ALA (250 mg / kg iv, 8 hours before ultrasound) and 8-minute pulse repetition at 100 Hz, 10% duty time ratio, 1.0 MHz, 2.5 W / cm daily for 10 days. 2Li used rat osteosarcoma UMR-106 cells in BALB / c nude mice treated daily with ultrasound at 100 rpm for 24 hours. He reported that mice receiving ultrasound alone exhibited smaller tumor volumes than mice receiving control or 5-ALA alone, and that mice receiving SDT exhibited tumor volumes that were significantly smaller than all other groups.

[0013] Further advances in sonodynamic therapy have often focused on improving sensitizers, increasing selectivity for malignant tissue, systemic distribution, or sensitivity to ultrasound. Woodburn et al., US20010002251, disclosed the use of texaphyrins as SDT sensitizers. Sanderson et al. disclosed the use of tetrasulfamoyl phthalocyanine and naphthalocyanine derivatives (GB2343186) and tetrasulfamoyl phthalocyanine and naphthalocyanine (GB2343186) as dyes to indicate diseased tissue and as sensitizers for SDT or PDT.

However, to date, sonodynamic therapy has not been approved by any regulatory agency for use in humans. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0021] Detailed Description One embodiment is a method of selectively inducing a direct cytotoxic effect in malignant tissue of a subject, comprising administering to the malignant tissue an effective amount of 5-aminolevulinic acid; and injecting the tissue at a concentration of about 3 W / cm. 2 ~about 100W / cm 2The method involves exposing tissue to ultrasound energy ("ultrasonic treatment") using a focused ultrasound device at a frequency of about 0.1 MHz to about 3 MHz, with an ultrasound beam focus intensity of 100 Hz. Direct cytotoxic effects include inducing cellular apoptosis, necrosis, and / or physical destruction. An effective amount of 5-ALA can be determined by standard methods. Generally, an effective amount is an amount sufficient to substantially stain the malignant tissue being treated without substantially staining normal tissue or inducing unacceptable levels of toxicity. Without being bound by any particular theory, it is believed that ultrasonic treatment of tissue causes cavitation and microbubbles (whose collapse produces photons with wavelengths of about 300 nm to 700 nm within the tissue), and these photons activate protoporphyrin IX, leading to tissue destruction.

[0022] When a range of values ​​is given herein, it is understood that each intervening value between the upper and lower limits of that range (to one-tenth of the unit of the lower limit unless expressly stated otherwise), as well as any other stated or intervening value in the stated range, is encompassed within the disclosed scope. The upper and lower limits of these narrower ranges may independently be included in the narrower ranges, which are also encompassed within the disclosed scope, subject to any specifically excluded limit in the stated range. When the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the disclosure.

[0023] All ranges disclosed herein also encompass any and all possible subranges and combinations thereof. Any recited range will be considered fully descriptive and allows for the same range to be divided into at least equal halves, thirds, fifths, tenths, etc. As a non-limiting example, each range discussed herein can be readily divided into a lower third, middle third, upper third, etc. As will be apparent to one of ordinary skill in the art, all language such as "up to," "at least," "greater than," "less than," etc., refers to a range that includes the recited numbers and can be subsequently divided into subranges as previously described. Finally, as will be apparent to one of ordinary skill in the art, a range includes each individual number. Thus, for example, a group having 1 to 3 items refers to a group having 1, 2, or 3 items. Similarly, a group having 1 to 5 items refers to a group having 1, 2, 3, 4, or 5 items, etc.

[0024] It is understood that certain features of the disclosure (which are, for clarity, described in the context of separate embodiments) may also be provided in combination in a single embodiment. Conversely, various features of the disclosure (which are, for brevity, described in the context of a single embodiment) may also be provided separately or in any suitable subcombination. All combinations of the embodiments relevant to the disclosure are specifically embraced by the present disclosure and are disclosed herein exactly as if each and every combination were individually and explicitly disclosed. In addition, all subcombinations of the various embodiments and elements thereof are also specifically embraced by the present disclosure and are disclosed herein exactly as if each and every such subcombination were individually and explicitly disclosed herein.

[0025] Malignant tissue Malignant tissues are typically tumorous or cancerous, but may generally be any type of tissue capable of absorbing 5-ALA and accumulating protoporphyrin IX, such as benign tumors or other unwanted growths. Focused ultrasound can penetrate intercalated tissues, allowing for the treatment of malignant tissues located in otherwise inaccessible locations. For this reason, the disclosed methods are useful for treating intracranial tumor types, such as glioblastoma multiforme (including low- and high-grade glioblastoma), optic pathway glioma, diffuse intrinsic pontine glioma, astrocytoma, ependymoma, medulloblastoma, oligodendroglioma, hemangioblastoma, rhabdoid tumor, brain metastases from other cancers (including, but not limited to, breast adenocarcinoma, small cell lung cancer, non-small cell lung cancer, squamous cell lung cancer, metastatic malignant melanoma, and prostate cancer), meningioma, primary pituitary malignant tumor, malignant nerve sheath tumor, and neurofibroma. Other malignancies include, but are not limited to, neoplasms, carcinomas, sarcomas, leukemias, lymphomas, etc. Leukemias and lymphomas include, for example, cutaneous T-cell lymphoma (CTCL), non-cutaneous peripheral T-cell lymphoma, human T-cell leukemia virus (HTLV)-associated lymphomas such as adult T-cell leukemia / lymphoma (ATLL), acute lymphocytic leukemia, acute non-lymphocytic leukemia, chronic lymphocytic leukemia, chronic myelogenous leukemia, Hodgkin's disease, non-Hodgkin's lymphoma, and multiple myeloma.

In some embodiments, the malignant tissue is glioblastoma multiforme, astrocytoma, ependymoma, medulloblastoma, oligodendroglioma, hemangioblastoma, or rhabdoid tumor. In some embodiments, the malignant tissue is glioblastoma multiforme.

[0027] 5-aminolevulinic acid 5-ALA can be provided in any pharmaceutically acceptable formulation, and may be provided as the free acid, a pharmaceutically acceptable salt, or a pharmaceutically acceptable ester. One formulation, Gliolan®, is commercially available.

NY Wiley-Interscience. Pharmaceutically acceptable salts are salts that retain the biological effectiveness and properties of the parent compound and are not biologically or otherwise undesirable. 5-ALA can form acid and / or base salts in the presence of amino and / or carboxyl groups. Many such salts are known in the art, for example, as described in WO 87 / 05297. Pharmaceutically acceptable acid addition salts can be formed using inorganic and organic acids.

Pharmaceutically acceptable esters include those obtained by replacing the hydrogen of an acidic group with an alkyl group, for example, by reacting the acidic group with an alcohol or a haloalkyl group.Examples of esters include, but are not limited to, those in which the hydrogen of a -C(O)OH group is replaced with an alkyl to form -C(O)O-alkyl.

[0029] In some embodiments, 5-ALA is sterilized by gamma irradiation (see US Pat. No. 6,335,465, incorporated herein by reference in its entirety). 5-ALA formulations can be administered orally, intravenously, intrathecally, or intratumorally. In some embodiments, 5-ALA is administered intravenously. In some embodiments, gamma-irradiated 5-ALA is administered intravenously. In some embodiments, 5-ALA is administered at a dosage of at least about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 96, 97, 98, 99, 100, 120, 125, 150, 175, 200, 300, 400, 500, 600, 750, or at least about 1000 mg / kg. In some embodiments, 5-ALA is administered at a dosage of about 1000, 900, 800, 700, 600, 500, 400, 300, 250, 200, 180, 175, 160, 150, 140, 130, 120, 110, 100, 90, 80, 70, 60, 50, 45, 40, 35, 30, 25, or 20 mg / kg or less. In some embodiments, 5-ALA is administered at a dosage of about 0.5 to about 250 mg / kg. In some embodiments, 5-ALA is administered at a dosage of 1 to 150 mg / kg. In some embodiments, 5-ALA is administered at a dosage of 5 to 90 mg / kg. In some embodiments, 5-ALA is administered at a dosage of 10 to 40 mg / kg.

[0030] The effective amount of 5-ALA required can be determined by standard methods known to those skilled in the art. For example, as described in Example 1 herein, one skilled in the art can implant tumor tissue into mice or other laboratory model subjects and treat the subjects with various amounts of 5-ALA and FUS. As shown in Figure 1, rats were treated with 20 mg / kg of 5-ALA, followed by 20 minutes of 6.9 W / cm 2 , 13.8W / cm 2 , 27.6W / cm 2 , or 55.2 W / cm 2 The result was 13.8W / cm 2 This shows that ultrasound treatment at 27.6 W / cm raised tumor temperature by approximately 2°C to 32°C. 2 Ultrasound treatment at 55.2 W / cm raised tumor temperature to approximately 37°C. 2 The rats treated with ultrasound at 1000 rpm suffered tissue damage of 32 ± 10 mm compared with the untreated control group. 3 The normalized tumor volume of the 5-ALA-only and FUS-only groups was 24±6 mm. 3 The normalized tumor volume was 100 mg / kg to 500 mg / kg. In some embodiments, the effective amount of 5-ALA is 1 mg / kg to 750 mg / kg. In some embodiments, the effective amount of 5-ALA is 10 mg / kg to 750 mg / kg. In some embodiments, the effective amount of 5-ALA is 20 mg / kg to 500 mg / kg. In some embodiments, the effective amount of 5-ALA is 40 mg / kg to 500 mg / kg.

[0032] Enhancer In some embodiments, the method further comprises administering a potentiating agent that enhances the therapeutic effect of 5-ALA, for example, by promoting the uptake or accumulation of protoporphyrin IX and / or 5-ALA or by slowing the rate at which protoporphyrin IX and / or 5-ALA are metabolized. The potentiating agent may thereby reduce the amount of 5-ALA required to achieve a given effect, or may enhance the effect achieved from a given amount of 5-ALA, or any combination of effect and amount in between. Suitable potentiating agents include, but are not limited to, methotrexate, doxycycline, minocycline, vitamin D3, and derivatives thereof. See, e.g., D.-F. Yang et al., J Formos Med Assoc (2014) 113(2):88-93; M.-J. Lee et al., PLoS ONE (2017) 12(5):e0178493; and EV Maytin et al., Isr J Chem (2012) 52(8-9):767-75. In some embodiments, the potentiator is selected from the group consisting of methotrexate, doxycycline, minocycline, vitamin D3, and derivatives thereof.

In some embodiments, the potentiator is vitamin D3. In some embodiments, a combination of two or more potentiators is used. In some embodiments, a combination of two or more of methotrexate, doxycycline, minocycline, and vitamin D3 is used.

[0033] The augmenting agent is administered simultaneously with 5-ALA or at another time prior to ultrasound treatment. The optimal time for administering the augmenting agent may vary depending on the choice of augmenting agent or combination of agents. In some embodiments, the augmenting agent is administered simultaneously with 5-ALA. In some embodiments, the augmenting agent is administered in the same formulation as 5-ALA. In some embodiments, the augmenting agent is administered at different times. In some embodiments, the augmenting agent is administered before administration of 5-ALA. In some embodiments, the augmenting agent is administered at least about 30 minutes, at least about 1 hour, at least about 2 hours, at least about 3 hours, at least about 4 hours, at least about 5 hours, at least about 6 hours, at least about 7 hours, at least about 8 hours, at least about 9 hours, at least about 10 hours, at least about 11 hours, at least about 12 hours, at least about 13 hours, at least about 14 hours, at least about 15 hours, at least about 16 hours, at least about 18 hours, at least about 20 hours, at least about 24 hours, at least about 36 hours, at least about 48 hours, at least about 3 days, at least about 4 days, at least about 5 days, or at least about 6 days before the first ultrasound treatment.

In some embodiments, the administration period of the augmenting agent is 48 to 96 hours prior to ultrasound treatment. In some embodiments, the administration period of the augmenting agent is 4 to 18 hours prior to ultrasound treatment.

[0034] The amount of the enhancer to be administered can be determined by one skilled in the art and generally depends on the enhancer(s) selected or the degree of enhancing effect to be achieved. Suitable methods include, but are not limited to, cell culture assays and / or in vivo experiments using model animals or explanted tissues to measure the degree of cell killing using various amounts of 5-ALA and / or enhancers together with either ultrasound treatment or photodynamic treatment. See, for example, D.-F. Yang et al., J Formos Med Assoc (2014) 113(2):88-93; M.-J. Lee et al., PLoS ONE (2017) 12(5):e0178493; and EV Maytin et al., Isr J Chem (2012) 52(8-9):767-75.

[0035] The amount of potentiator used is less than the amount that would result in unacceptable toxicity, and is great enough to reduce the amount of 5-ALA required to achieve a potentiating effect. The amount or number of malignant tissues or cells killed can be measured using a range of 5-ALA amounts as a baseline for comparison, and then the amount or number of malignant tissues or cells killed can be measured using the same amount of 5-ALA combined with various concentrations or amounts of an enhancer. Alternatively, one skilled in the art can measure the amount of 5-ALA required to produce the same level of killing in the presence of various concentrations or amounts of an enhancer. The amount or number of malignant tissues or cells killed can be measured by cell counting, measuring tumor volume, vital dye exclusion, and other techniques commonly used in medical research. The effect obtained using an enhancer is an increase in effect or a reduction in the dose of 5-ALA of at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 96, 97, 98, or 99% from the baseline standard. In some embodiments, the effect achieved with the potentiator is at least a 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 96, 97, 98, 99, 100, 120, 125, 150, 175, 200, 300, 400, 500% increase in effect from the baseline measure of extent of kill. In some embodiments, the effect achieved with the potentiator is at least a 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 96, 97, 98% or 99% reduction in the amount of 5-ALA required to achieve the baseline kill rate.

[0036] The amount of potentiator may be greater than, equal to, or less than the amount normally or typically prescribed for use of the potentiator alone. The upper limit is the amount at which unacceptable toxicity occurs, alone or in combination with 5-ALA. The lower limit is the amount required to achieve a measurable enhancing effect, which may be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 96, 97, 98, 99, 100, 120, 125, 150, 175, or 200% of the typical dose. For example, but not limited to, methotrexate may be administered as a single oral dose of about 7.5 mg to 10 mg 24 to 72 hours prior to ultrasound treatment; doxycycline may be administered at a dose of 100 mg BID starting with a loading dose of 200 mg starting 2 to 4 days prior to ultrasound treatment; minocycline may be administered at a dose of 50 to 100 mg BID starting 2 to 4 days prior to ultrasound treatment; and vitamin D3 may be administered as cholecalciferol at a dose of 10,000 to 100,000 IU / day 2 to 4 days prior to ultrasound treatment.

[0037] Microbubbles Microbubbles (also known as microspheres) are gas-filled spheres with diameters on the order of 1–5 μm. Because their echogenic properties aid in distinguishing fluid-filled blood vessels from surrounding tissue, they are sometimes used as contrast agents in medical ultrasonography. See, for example, PA Dijkmans et al., Eur J Cardiology (2004) 5:245–56. The gas is often air, nitrogen, sulfur hexafluoride, or a perfluorocarbon, such as octafluoropropane. The outer shell of a microbubble is often albumin, galactose, lipid, or polymer. In an ultrasound acoustic field, microbubbles undergo linear oscillations at low powers and nonlinear oscillations at higher powers, leading to lacerations at high powers. The frequency at which a microbubble resonates is primarily determined by the choice of gas in the core and the mechanical properties of the outer shell. Mixtures of two or more different types of microbubbles may be used. In practicing the methods of the present disclosure, microbubbles can be used to cause cavitation (and consequently, death of target cells) at lower acoustic powers than would otherwise be obtainable, hi some embodiments, an effective amount of microbubbles is administered to malignant tissue.

[0038] An effective dose of microbubbles is an amount sufficient to enhance the direct cytotoxic effect of 5-ALA or FUS on malignant tissue by at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 96, 97, 98, 99, 100, 120, 125, 150, 175, 200, 300, 400, or 500% above baseline criteria for extent of killing. Alternatively, an effective amount of microbubbles may be expressed as an amount sufficient to reduce the 5-ALA dose or FUS dose by at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 96, 97, 98, or 99% from a baseline level.

[0039] Microbubbles may be prepared by methods known in the art or obtained from commercial sources. Suitable microbubbles include, but are not limited to, high-contrast ultrasound microbubbles, such as Definity® perflutren lipid microbubbles (Lantheus Medical Imaging, N. Billerica, MA), Levovist® lipid / galactose microspheres (Schering), Optison® microbubbles (GE Healthcare), and Lumason® microbubbles (Bracco Imaging, Monroe Township, NJ). In some embodiments, the microbubbles are high-contrast ultrasound microbubbles. In some embodiments, the microbubbles comprise sulfur hexafluoride or a perfluorocarbon. In some embodiments, the perfluorocarbon is octafluoropropane or perfluorohexane. In some embodiments, the microbubbles comprise air or nitrogen. In some embodiments, the microbubble shell comprises albumin. In some embodiments, the microbubbles are Definity® perflutren lipid microbubbles, Levovist® lipid / galactose microspheres, Optison® microbubbles, or Lumason® microbubbles.

[0040] Microbubbles can be administered with 5-ALA and / or a potentiating agent depending on the half-life of the microbubbles in the subject's system. Generally, many microbubble agents have a very short half-life in the human circulation, and therefore are typically administered immediately before ultrasound treatment. The amount and method of administration are similar to those used by those skilled in the art when administering microbubbles for contrast-enhanced ultrasound ultrasonography. The amount administered is at least 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 120, 140, 150, 160, 180, 200, 250, 300, 350, or 400% of the amount used or recommended for use as a contrast-enhanced ultrasound ultrasonography agent. The amount administered is no more than 500, 450, 400, 350, 300, 250, 200, 150, 100, 90, 80, 75, 70, 60, 50, 45, 40, 35, 30, 25, or 20% of the amount used or recommended for use as an ultrasound imaging agent in contrast-enhanced ultrasound.

[0041] focused ultrasound Malignant tissue is exposed to focused ultrasound energy ("ultrasonic treatment") using a focused ultrasound (FUS) device. Suitable devices include the Exablate® Model 4000 Type-2 system (Insightec, Dallas, TX). The Type-2 has a dedicated 1000-element transducer that can operate in an ultrasound treatment mode (i.e., focused ultrasound pressure wave delivery mode) using a short-duration duty cycle to create "burst ultrasound treatment" at low power. This burst ultrasound treatment mode, when used in conjunction with microbubbles at energy levels much lower than ultrasound-induced cavitation, allows the device to induce stable cavitation. Microbubble oscillation induces temporary, reversible, well-targeted, yet stable blood-brain barrier disruption. A notable feature of the Exablate® device is its ability to monitor acoustic feedback in real time to ensure safe and effective BBB disruption. The Exablate® device is a magnetic resonance guided focused ultrasound (MRgFUS) device, and as such, it utilizes real-time MR imaging to assess and monitor procedural safety.

[0044] The FUS energy applied during sonodynamic treatment is generally less than the amount of energy used when using FUS to ablate tissue, and can be further reduced when microbubbles are administered prior to ultrasound treatment. In some embodiments, the applied FUS energy is at least 10, 20, 30, 40, 50, 60, 70, 75, 80, 90, 100, 125, 150, 175, 200, 225, 250, 275, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750, 800, 900, 1000, 1200, 1400, 1600, 1800, or 2000 Joules. In some embodiments, the applied FUS energy is less than or equal to 5000, 4000, 3000, 2500, 2250, 2000, 1900, 1800, 1700, 1600, 1500, 1400, 1300, 1250, 1200, 1150, 1100, 1050, 1000, 950, 900, 850, 800, 750, 700, 650, 600, 550, 500, 450, 400, 350, 300, or 250 J.

In some embodiments, the FUS energy applied is between 250 J and 1250 J. In some embodiments, the FUS energy applied is between 500 J and 1250 J.

[0045] The duration of ultrasound treatment varies depending on the subject, the specific type and stage of the malignant tissue, the location and amount of malignant tissue, and the extent to which the malignant tissue takes up 5-ALA and accumulates protoporphyrin IX. In some embodiments, the malignant tissue is ultrasound-treated at multiple points, e.g., multiple points within a tumor. As used herein, "point" refers to the focus of FUS and points surrounding the tissue affected by FUS. By ultrasound-treating points distributed throughout the malignant tissue, practitioners can achieve a more uniform and consistent effect throughout the tumor volume. This also allows practitioners to use lower power, which reduces the likelihood of temperature (and therefore potential risk to surrounding normal tissue) elevation. In some embodiments, the malignant tissue is ultrasound-treated at individual points, exposing all of the malignant tissue together to FUS. In some embodiments, the points overlap. The points can be ultrasound-treated simultaneously, individually, or in groups. For example, in a treatment involving targeting 16 points, all 16 points may be sonicated simultaneously, or the points may be sonicated sequentially or in random order, or in groups of, for example, two or three, or other sizes. When groups are sonicated, the groups may be physically grouped or distributed in non-contiguous areas. In some embodiments, malignant tissue is sonicated at 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 15, 20, 25, or 30 individual points, or any value between 1 and 30. In some embodiments, malignant tissue is sonicated at 30, 25, 20, 19, 18, 17, 16, 15, 14, 13, 12, 11, or 10 or fewer individual points.

[0046] In some embodiments, the ultrasound treatment duration is at least about 20 seconds, at least about 30 seconds, at least about 45 seconds, at least about 1 minute, at least about 2 minutes, at least about 3 minutes, at least about 4 minutes, at least about 5 minutes, at least about 6 minutes, at least about 7 minutes, at least about 8 minutes, at least about 9 minutes, at least about 10 minutes, at least about 15 minutes, at least about 20 minutes, at least about 30 minutes, at least about 45 minutes, at least about 60 minutes, at least about 75 minutes, at least about 90 minutes, at least about 105 minutes, at least about 120 minutes, at least about 135 minutes, at least about 150 minutes, at least about 165 minutes, at least about 180 minutes, at least about 195 minutes, at least about 210 minutes, at least about 230 minutes, at least about 245 minutes, at least about 260 minutes, at least about 275 minutes, at least about 300 minutes, at least about 330 minutes, or at least about 360 minutes. In some embodiments, the ultrasound treatment duration is less than about 360 minutes, less than about 330 minutes, less than about 300 minutes, less than about 290 minutes, less than about 280 minutes, less than about 270 minutes, less than about 260 minutes, less than about 250 minutes, less than about 240 minutes, less than about 230 minutes, less than about 220 minutes, less than about 210 minutes, less than about 200 minutes, less than about 195 minutes, less than about 190 minutes, less than about 185 minutes, less than about 180 minutes, less than about 170 minutes, less than about 160 minutes, less than about 150 minutes, less than about 140 minutes, less than about 130 minutes, less than about 120 minutes, less than about 110 minutes, less than about 100 minutes, less than about 90 minutes, less than about 80 minutes, less than about 70 minutes, less than about 60 minutes, less than about 50 minutes, less than about 40 minutes, less than about 30 minutes, less than about 20 minutes, or less than about 10 minutes.

[0047] Ultrasound treatment can be continuous or periodic. In periodic ultrasound treatment, periods of exposure to focused ultrasound ("ultrasound treatment periods") are interspersed with rest periods without ultrasound treatment.

[0072] The following preparations and examples are given to enable those skilled in the art to more clearly understand and to practice the present invention, and should not be considered as limiting the scope of the invention, but merely as being illustrative and representative thereof.

[0073] Example 1 Treatment method Male Wistar rats received 4 × 10 5 Injections of C6 glial tumor cells were given to rats. On the seventh day after injection, 3 hours before treatment, rats were orally administered 5-aminolevulinic acid (20 mg / kg or 0 mg / kg, Levulan®, DUSA Pharmaceuticals, Wilmington, MA).

[0074] Rats were anesthetized and placed in an MRI-guided focused ultrasound system ("FUS", RK300, FUS Instruments, Toronto, Canada) with a 25 mm diameter spherically curved transducer (resonant frequency f = 1.06 MHz, focal number = 0.8). The FUS with the rat was then inserted into a 7 Telsa MRI system (Brucker BioSpec 70 / 30 USR, Bruker Ltd., Milton, Ontario, Canada). MRI was used to precisely target the FUS device at the brain tumor. The rats were then monitored for four spatial-peak temporal-average intensities (I) over a 20-minute period. SPTA )(6.9W / cm 2 , 13.8W / cm 2 , 27.6W / cm 2 , or 55.2 W / cm 2 One group (N=6) was treated with ultrasound at 27.6 W / cm for 20 minutes. 2 The tumors were periodically sonicated at 1000 rpm, divided into 16 85-second sonication sessions separated by 60-second rest periods (multiple-point, or "MP" group). In the MP group, 16 individual points within the tumor were sonicated. Control groups (N=5 each) received 5-ALA without FUS, FUS treatment without 5-ALA, or neither 5-ALA nor FUS treatment. Tumor temperature was monitored during sonication using a magnetic resonance thermometer. Normalized tumor volume was measured by MRI at 7, 14, 21, 28, and 35 days after injection.

[0075] result 13.8W / cm 2 Ultrasound treatment at 27.6 W / cm raised tumor temperature by approximately 2°C to 32°C. 2 Ultrasound treatment at 55.2 W / cm raised tumor temperature to approximately 37°C. 2 The rats treated with ultrasound at 1000 Hz suffered tissue damage and were euthanized. The untreated control group had a 32±10 mm 3 The normalized tumor volume of the 5-ALA-only and FUS-only groups was 24±6 mm. 3The normalized tumor volume of 100 mg / kg / day was 100 mg / kg / day. All experimental groups showed inhibited tumor growth (see Figure 1) and improved survival (see Figure 2). The MP group showed the greatest prolongation of survival. Example 2

[0076] This study was conducted to demonstrate the safety and tolerability of treatment with 5-ALA and MRgFUS.

[0077] Treatment method Human subjects will be selected who meet the following criteria: (a) presence of recurrent glioma (WHO grade 3 or 4); (b) prior treatment using the Stupp protocol; and (c) planned tumor resection. The Stupp protocol consists of daily administration of temozolomide (75 mg / m) over 6 weeks of radiation therapy. 2 Radiotherapy was administered at 2 Gy per 6-week period, Monday through Friday, for a total of 60 Gy, followed by six cycles of temozolomide (150–200 mg / m²) for 5 days of each 28-day cycle after completion of radiotherapy. 2 ) (R. Stupp et al., New Engl J Med (2005) 352:987-96).

[0078] Each subject is treated with intravenous 5-ALA and MRgFUS at the amounts specified in Table 1 below, two to four weeks prior to the subject's planned craniotomy. In each subject, FUS is focused on half of the tumor, including enhancing and non-enhancing areas. Treatment is initially performed with dose level 1, and subjects are examined for dose-limiting toxicity (DLT). If no DLT is observed, the next cohort of subjects is treated with dose level 2. This escalation is repeated for each cohort unless a DLT is observed. If one DLT is observed, that dose level is repeated in the next cohort with an expansion of three additional subjects. If two or more DLTs are observed, the prior dose level is designated as the maximum tolerated dose.

[0079] [Table 1]

[0080] result Tumors are monitored periodically by MRI or X-ray imaging prior to resection. Following tumor resection, the excised tumors are examined for differences between the ultrasound-treated and non-ultrasound-treated halves, including size reduction or histological grade.
