Description

[Technical Field]

[0001] Described herein is a novel method for treating bone fractures using low intensity pulsed ultrasound. [Background technology]

[0002] Fractures are common injuries for individuals worldwide. Rehabilitation after injury can be a lengthy process, resulting in impaired mobility and function. Patients may also experience delayed union or nonunion, respectively. An estimated 10% of individuals suffer from improper healing (Einhorn et al., 2014). The normal healing process begins with an inflammatory phase after injury, which initiates matrix formation and solidification. This is followed by a fibrovascular phase to remodel damaged blood vessels and restore nutrient supply. Revascularization leads to the bone formation phase. Stem cells necessary for bone growth are then recruited and can differentiate into either osteoblasts, chondrocytes, or other bone-forming cells to complete the restoration of bone structure at the fracture site (Bahney et al., 2019).

[0003] One approach to treating fractures is the use of therapeutic ultrasound to accelerate and support proper healing. A typical treatment consists of low-intensity pulsed ultrasound in an optimal frequency range for an optimal duration. Ultrasound provides cyclical mechanical sound waves passing through tissue, which may support all biological stages of bone healing. Vascular remodeling and early bone growth are also promoted by ultrasound therapy through modulation of growth-related and differentiation signaling. Finally, ultrasound is thought to support the bone remodeling phase in a manner similar to mechanical force or physical loading (Jiang et al., 2018).

[0004] Poor patient compliance presents an additional hurdle to recovery and healing, especially when patients are required to self-administer the therapy. However, direct feedback compliance of patients self-administering ultrasound therapy has been found to significantly impact patient compliance (Pounder et al., 2016).

"Pharmaceutically acceptable" means that the carrier, diluent, or excipient must be compatible with the other ingredients of the formulation, including the vector described herein, and not deleterious to the recipient thereof. A "pharmaceutically acceptable carrier" is any carrier that is relatively non-toxic and innocuous to a patient at concentrations consistent with the effective activity of the active ingredient, such that any adverse side effects attributable to the carrier do not impair the beneficial effects of the active ingredient.

[0026] As used herein, the term "continuous treatment" refers to continuous daily treatment using low intensity pulsed ultrasound in a particular setting.

[0027] As used herein, the term "pseudounion" refers to a fracture that has not healed. The most agreed-upon definition of a nonunion is a fracture that persists for three months without signs of healing. A nonunion may also refer to a nonhealed fracture that shows no signs of healing after clinical evaluation when examined by a physician and using serial radiographs taken at 45-90 day intervals.

[0028] "Patient" or "subject," as used herein, refers to a mammalian subject who has been diagnosed with or is suspected of having a fracture. In some embodiments, the term "patient" refers to a mammalian subject who has a higher-than-average likelihood of developing a non-union fracture. Exemplary patients can be humans, apes, dogs, pigs, cows, cats, horses, goats, sheep, rodents, and other mammals that may benefit from the therapies disclosed herein. Exemplary human patients can be male and / or female. "Patient in need thereof" or "subject in need thereof," as used herein, refers to a patient who has been diagnosed with or is suspected of having a disease or disorder, such as, but not limited to, rheumatoid arthritis.

[0029] "Administering," as used herein, refers to providing one or more compositions or therapies described herein to a patient or subject. By way of example and not limitation, administration, e.g., injection, of a composition can be performed by intravenous (i.v.), subcutaneous (i.c.), intradermal (i.d.), intraperitoneal (i.p.), or intramuscular (i.m.) injection. One or more such routes can be used. Parenteral administration can be, for example, by bolus injection or slow perfusion over time. Alternatively, or concurrently, administration can be by oral route. Additionally, administration can also be by surgical deposition of a bolus or pellet of cells or positioning of a medical device. In one embodiment, a composition of the present disclosure can comprise a gel used with a low-intensity pulsed ultrasound device in an amount effective to treat or heal a fracture. Administering may further refer to administering a therapy of the present disclosure, which may include administering low intensity ultrasound in an amount effective to treat, repair, or promote healing of a bone fracture in a patient in need of treatment of the bone fracture.

[0030] As used herein, the terms "treatment," "treating," or grammatical equivalents thereof, refer to obtaining a desired pharmacological and / or physiological effect. In some embodiments, the effect is therapeutic, i.e., the effect partially or completely cures a disease and / or condition. In some embodiments, the term "treating" can include inhibiting or "preventing" a disease or condition, including treating a bone fracture. In some embodiments, the term "treating" can include "repairing" or "healing" a bone fracture.

[0031] As used herein, a "treatment interval" refers to a treatment cycle, e.g., a course of administration of a therapeutic agent or therapy, which may be repeated on a regular schedule. In some embodiments, a dosing regimen may have one or more periods without administration of a therapeutic agent during the treatment interval.

[0032] The terms "therapeutically effective amount," "therapeutic amount," or grammatical equivalents thereof, refer to an amount effective, at a dosage or setting, for a period of time necessary, to achieve a desired therapeutic result. A therapeutically effective amount may vary depending on factors such as an individual's disease state, age, sex, and weight, and the ability of the compositions described herein to induce a desired response in one or more subjects. The exact amount of a composition or therapy of the present disclosure to be administered can be determined by a physician, taking into account the patient's (subject's) age, weight, tumor size, degree of inflammation, infection, or metastasis, and individual differences in the condition. For example, a therapeutically effective amount of low-intensity pulsed ultrasound may be the amount, specific setting, recommended by a medical device manufacturer or prescribed by a physician over a treatment period.

[0033] As used herein, the term "treatment period" refers to the administration of a specific medical treatment, e.g., low-intensity pulsed ultrasound treatment for a bone fracture, administered in a specific setting over a period of time, e.g., several days. Thus, a treatment period can include the administration of low-intensity pulsed ultrasound over a treatment period of, e.g., 1-120 days, 1-90 days, 1-60 days, 1-30 days, or 1-15 days.

[0034] For the recitation of numerical ranges herein, each intervening number is expressly contemplated to the same degree of precision. For example, for the range 6 to 9, the numbers 7 and 8 are contemplated in addition to 6 and 9, and for the range 6.0 to 7.0, the numbers 6.0, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9, and 7.0 are expressly contemplated.

[0035] This disclosure describes a novel method for treating bone fractures using low-intensity ultrasound that includes tracking tools to aid patient adherence and results in clinically significant healing in a shorter time than the current standard of care.

[0036] While successful treatments for fractures currently exist, the duration of treatment after injury remains a challenge to positive patient outcomes. Elderly patients or those with comorbidities are more susceptible to complications in healing and recurrence than those without. The use of ultrasound to therapeutically treat and evaluate bone injuries is known. However, the success of ultrasound treatment depends on patient compliance with the treatment regimen. (Harrison et al., 2021) A shorter treatment period has been shown to increase patient compliance and provide positive economic benefits due to shorter healing times and reduced risk of improper healing. (Sklar et al., 2008) Accordingly, one embodiment described herein is a method of treating a fracture in a patient in need of treatment using low-intensity pulsed ultrasound.

[0037] Ultrasound delivery systems generally use pulsed high-frequency waves (in the MHz range) to treat bone fractures. These systems utilize the piezoelectric properties of bone. When ultrasound waves are applied to a fractured bone, they are converted into electrical currents within the bone to promote healing through small deflections within the bone. Such systems are well known, including those described in, for example, U.S. Pat. Nos. 5,003,965, 5,186,162, 5,556,372, and the EXOGEN® Ultrasound System, all of which are incorporated herein by reference for their general teachings. However, other ultrasound application devices can be used in the methods described herein. In one aspect, the ultrasound waves are low-intensity pulsed ultrasound waves.

[0038] Ultrasound therapy can be used to treat fractures of any bone type, including the long and short bones of the arms and legs, the short bones of the wrist and ankle, flat bones such as the scapula, sternum, and skull, and irregular bones such as the vertebrae. In one aspect, the bone includes the humerus, metatarsal, and ankle. In one aspect, the bone includes the distal phalanx of the thumb, the proximal phalanx of the thumb, or a phalange, including any of the distal, middle, or proximal phalanges. In another aspect, the bone includes a metacarpal. In another aspect, the bone includes the carpal bones, including the ulna and radius, the trapezoid, the trapezoid, the capitate, the navicular, the lunate, the triquetrum, the hamate, or the uncinate. In another aspect, the bone includes any of the bones of the leg, including the femur, patella, tibia, or fibula. In one aspect, the bone includes the navicular or tibia.

[0039] Ultrasound therapy treatment may involve the administration of ultrasound therapy at specific settings and for a defined treatment period. Treatment settings include specified intensity, frequency, and wavelength. For example, the EXOGEN® Ultrasound Bone Healing System (Model Number 71034400) device provides 30 mW / cm 2 The standard settings are used: power density of 1 kHz, a 1.5 MHz signal, and punctuality of 1 kHz, 20% duty cycle. Thus, in one aspect, treatment may include daily treatment with standard settings for a low intensity pulsed ultrasound device.

[0040] The current standard of care for fractures includes cast immobilization and non-surgical treatment (e.g., https: / / www.aafp.org / pubs / afp / issues / 2004 / 0901 / p879.html). The standard of care for low-intensity pulsed ultrasound is limited to treatment with a device set for a prescribed number of minutes for daily use. However, clinicians vary in the number of days such treatment should be continued (i.e., the treatment duration over several days). Thus, while patients may comply with daily use, adherence to the treatment duration appropriate for complete healing remains uncertain. Furthermore, patient adherence to the set treatment duration is difficult. A survey of clinicians using low-intensity pulsed ultrasound devices to treat fractures found that clinicians continue using such therapy until complete healing, but generally prescribe use for 70 to 90 days, as seen in Figure 1.

[0041] In one embodiment of the methods described herein, the administration of low intensity pulsed ultrasound to the patient comprises a daily treatment for about 10 minutes to about 30 minutes, about 15 minutes to about 20 minutes, about 10 minutes, about 15 minutes, about 20 minutes, about 25 minutes, or about 30 minutes. In one embodiment, the administration of low intensity pulsed ultrasound to the patient comprises a daily treatment for about 20 minutes. In another embodiment of the methods described herein, the administration of low intensity pulsed ultrasound to the patient comprises a once-daily, twice-daily, or three-daily treatment. A treatment period can include one or more treatments over a specific time interval. In one aspect, the treatment period comprises daily treatment with standard device settings for about 1 to about 10 consecutive days, about 1 to about 15 consecutive days, about 1 to about 20 consecutive days, about 1 to about 25 consecutive days, about 1 to about 30 consecutive days, about 1 to about 45 consecutive days, about 1 to about 50 consecutive days, about 1 to about 65 consecutive days, about 1 to about 75 consecutive days, about 1 to about 80 consecutive days, about 1 to about 90 consecutive days, about 1 to about 100 consecutive days, about 1 to about 115 consecutive days, about 1 to about 120 consecutive days, about 1 to about 125 consecutive days, about 1 to about 135 consecutive days, or about 1 to about 150 consecutive days.

[0042] In yet another embodiment of the methods described herein, the patient is administered low intensity pulsed ultrasound for 1 to about 120 consecutive treatments ("consecutive treatments" refers to consecutive daily treatments), 1 to about 90 consecutive treatments, 1 to about 60 consecutive treatments, 1 to about 30 consecutive treatments, 1 to about 15 consecutive treatments, about 2 to about 10 consecutive treatments, about 5 to about 20 consecutive treatments, about 10 to about 25 consecutive treatments, about 15 to about 25 consecutive treatments, about 20 to about 30 consecutive treatments, about 25 to about 35 consecutive treatments, about 30 to about 40 consecutive treatments, about 35 to about 45 consecutive treatments, about 40 to about 50 consecutive treatments, or the like. The preferred treatments include about 10 consecutive treatments, about 18 consecutive treatments, about 25 consecutive treatments, about 30 consecutive treatments, about 45 consecutive treatments, about 60 consecutive treatments, about 75 consecutive treatments, about 80 consecutive treatments, about 90 consecutive treatments, about 100 consecutive treatments, about 18 consecutive treatments, about 25 consecutive treatments, about 30 consecutive treatments, about 45 consecutive treatments, about 60 consecutive treatments, about 75 consecutive treatments, about 90 consecutive treatments, or about 120 consecutive treatments. In one aspect of the methods described herein, the administration of low intensity pulsed ultrasound to the patient comprises a single treatment per day for 20 minutes, for 30 days, for 45 days, for 60 days, for 75 days, for 90 days, or for 120 days. In another aspect, the administration of low intensity pulsed ultrasound to the patient comprises continuous treatment (continuous daily treatment for a defined period of days). In another aspect of the methods described herein, the administration of low intensity pulsed ultrasound to the patient comprises a treatment interval.

[0043] Thus, in another aspect, the method further includes tracking the patient's treatment. Tracking includes recording the patient's treatment, including ongoing treatment, and progress toward treatment goals. Thus, tracking provides a means for patient compliance and encouragement. Various tools can be used to accomplish the recording and tracking. In one aspect, tracking includes the use of a compliance calendar. The compliance calendar includes a calendar that the patient uses not only to remind them of their treatment, but also to record their treatment and thus monitor their progress. The compliance calendar can include tracking treatments administered out of the total treatments required to reach a goal. In another aspect, tracking includes the use of a progress toward goal tool. The progress toward goal tool includes the number of treatments completed, the total treatment goal, and a timer to assist the patient in completing the treatment regimen. In another aspect, tracking includes the use of an adherence tracker that counts the number of complete treatments per day since the first treatment. In another aspect, tracking includes a continuity tracker that tracks the total number of consecutive treatment days to track and encourage the patient to adhere to continuous, uninterrupted daily treatment. An exemplary tracking tool is shown in FIG. 2.

[0044] In one aspect, bone healing includes complete healing. Complete healing refers to when a clinician determines that a fracture has healed, typically using radiographic and clinical evaluations to assess pain, range of motion, strength, and other parameters. Assessment of complete healing may result in cessation of further treatment. If complete healing is not achieved, the patient may continue treatment for an additional period of treatment as determined by the physician. In another aspect, bone healing includes clinically significant healing. Clinically significant healing refers to healing with a pseudarthrosis odds ratio of 1.5, meaning that patients not using low-intensity pulsed ultrasound are 1.5 times more likely to develop a pseudarthrosis than patients using low-intensity pulsed ultrasound.

[0045] It will be readily apparent to those skilled in the relevant art that suitable modifications and adaptations to the compositions, methods, and applications described herein can be made without departing from the scope of any embodiment or aspect thereof. The compositions and methods provided are exemplary and are not intended to limit the scope of any of the specified embodiments. All of the various embodiments, aspects, and options disclosed herein can be combined in any and all variations or iterations. The scope of the compositions, formulations, methods, and processes described herein includes all actual or potential combinations of the embodiments, aspects, options, examples, and preferences described herein. [Example]

[0046] Example 1 Low-Intensity Pulsed Ultrasound (LIPUS) Therapy to Reduce the Risk of Pseudoarthrosis in At-Risk Patients A 9-month study was conducted to demonstrate that treatment of scaphoid fractures with EXOGEN® is effective in reducing the incidence of fracture pseudarthrosis in patients at risk for scaphoid fractures compared to standard of care alone (including conservative fracture management with cast immobilization or surgical repair) using low-intensity pulsed ultrasound (LIPUS). The primary study endpoint was based on the incidence of scaphoid fracture pseudarthrosis, as measured by clinician diagnosis in the form of an International Classification of Diseases (ICD) pseudarthrosis diagnosis.

[0047] Target population: EXOGEN Treatment Cohort: Adult patients (ages 21-60) in the United States (US) at risk for developing a fracture nonunion who were prescribed EXOGEN® as adjunctive treatment for scaphoid fractures.

[0048] Treatment regimen: Patients received prescribed therapy with the EXOGEN® Ultrasound Bone Healing System (Model Number 71034400) for scaphoid fractures as identified by ICD-10-CM codes. The EXOGEN® product was used as administered, once daily for 20 consecutive minutes, through patient self-administered therapy at home or at work. Each patient was periodically evaluated by a physician and radiographed for this data. If a patient was not seen by a physician within the allotted time, they were excluded from the study.

[0049] The length of the treatment window was variable and determined by the treating clinician's assessment of the healing process. Clinicians generally recommend using the EXOGEN® System for the treatment of scaphoid fractures for 90 days to achieve complete healing, which refers to when the clinician determines that the fracture has healed. This is typically done through a combination of x-rays and clinical evaluation to determine pain, range of motion, strength, etc.

[0050] result: Figure 3 describes the results as the odds ratio (ITT) of nonunion for patients using EXOGEN® compared to the matched cohort. For this study, clinical significance was defined as an odds ratio of 1.5, indicating that the outcome of the control group with a nonunion fracture was 1.5 times that of the group using the EXOGEN® System for treatment. The p-value demonstrates statistical significance.

[0051] A correlation between clinical effectiveness and patient compliance with the use of low-intensity pulsed ultrasound has been reported (Pounder et al., 2016), with data showing that 8 out of 10 clinical trials with patient compliance greater than 72% reported successful outcomes, while 2 clinical trials reported insufficient patient compliance and resulted in unsuccessful outcomes. However, compliance was based on daily usage. Thus, while the results indicate that patients can achieve 100% treatment compliance with daily treatments, there is no indication of the total number of daily treatments required for complete cure. Therefore, the results described in Figure 2 further suggest that complete cure may occur with more days of daily treatment than the current standard of care prescribed by physicians.

[0052] Example 2 Future studies similar to those described above will be conducted using patients with tibial fractures.

[0053] Although the above disclosure has been described in some detail by way of illustration and example for purposes of clarity of understanding, it will be readily apparent to those skilled in the art that, in light of the teachings of the present invention, certain changes and modifications can be made thereto without departing from the spirit or scope of the appended claims. The following examples are provided by way of illustration only, and not by way of limitation. Those skilled in the art will readily recognize a variety of non-critical parameters that can be changed or modified to yield essentially similar results.
