DETAILED DESCRIPTION OF THE INVENTION
[0017] A, An, The: As used herein, the singular forms "a", "an", and "the" include plural referents unless the context clearly dictates otherwise.
[0018] About, Approximately: As used herein, the terms "about" and "approximately" are generally intended to mean an acceptable degree of error for the measured quantity considering the nature or precision of the measurement. Exemplary degrees of error are within 15 percent (%), typically within 10%, more typically within 5% of a given value or range of values.
[0019] A "polymer" is a substance composed of macromolecules. Polymer macromolecules are molecules with a high relative molecular weight, and their structure includes multiple repeating units derived from molecules with a low relative molecular weight.
[0020] A "branched polymer" is a polymer that includes side chains of repeating units (different from the side chains already present in the monomer) that are linked to the main chain of repeating units. A branched polymer refers to a non-linear polymer structure, but typically is not a network structure. Thus, there are no cross-links that return to the original main chain when traced forward from the branch point; that is, the cross-linked backbone is minimal or non-existent. Branched polymers are generally soluble in suitable solvents.
[0021] A "cross-linked polymer" is a polymer that includes inter-chain cross-links formed either during polymerization (by selection of monomers) or after polymerization (by addition of specific reagents). In a cross-linked polymer network, it is possible to trace continuous loops back to the backbone by cross-links that act as branch points. Cross-linked networks are insoluble in all solvents.
[0022] A "network polymer" is a cross-linked polymer that includes on average two or more linkages between chains, and the entire sample is, or potentially is, a single molecule. Limited cross-linking connections per chain are considered lightly cross-linked, while numerous cross-links are considered highly (or severely) cross-linked.
[0023] A "copolymer" is a substance created by polymerizing a mixture of two or more starting compounds. The resulting polymer molecules contain monomers in ratios related to both the molar fractions of the monomers in the starting mixture and the reaction mechanism.
[0024] As used herein, the terms "subject", "individual", or "patient" are used interchangeably and mean any animal, including mammals such as mice, rats, other rodents, rabbits, dogs, cats, pigs, cows, sheep, horses, or primates such as humans.
[0025] As used herein, the phrase "in need thereof" means that an animal or mammal is identified as having a need for a particular method or treatment. In some embodiments, the identification can be by any diagnostic means. In any of the methods and treatments described herein, an animal or mammal may be in need thereof. In some embodiments, the animal or mammal is in or moves to an environment where a particular disease, disorder or condition is prevalent. For example, in some embodiments, the subject is a subject in need of radiation treatment due to a condition such as skin cancer.
[0026] As used herein, the phrase "an integer from X to Y" means any integer including the endpoints. For example, the phrase "an integer from 1 to 5" means 1, 2, 3, 4 or 5.
[0027] As used herein, the term "mammal" means a rodent (i.e., mouse, rat or guinea pig), monkey, cat, dog, cow, horse, pig, or human. In some embodiments, the mammal is a human.
[0028] As used herein, the phrase "therapeutically effective amount" means the amount of an active compound, radioisotope or pharmaceutical formulation that elicits a biological or medical response being investigated by a researcher, veterinarian, physician or other clinician in a tissue, system, animal, individual or human. The therapeutic effect depends on the disorder or desired biological effect being treated. Thus, the therapeutic effect can be a decrease in the severity of symptoms associated with the disorder, and / or inhibition (partial or complete) of the progression of the disorder, or an improvement in the treatment, cure, elimination of the disorder or side effects. The amount required to elicit a therapeutic response can be determined based on the age, health status, build and gender of the subject. The optimal amount can also be determined based on observation of the subject's response to the treatment.
[0029] As used herein, the terms "treating," "being treated," or "treatment" mean both therapeutic treatment and prophylactic measures, the purpose of which is to alleviate (reduce) a undesired physiological condition, disorder or disease, or to obtain a beneficial or desired clinical outcome. Beneficial or desired clinical outcomes include, but are not limited to, alleviation of symptoms; reduction in the degree of a condition, disorder or disease; a stabilized (i.e., not worsening) condition, disorder or disease; delay in onset or slowing of progression of a condition, disorder or disease; amelioration or remission (partial or total) of a condition, disorder or disease state, whether detectable or undetectable; amelioration of at least one measurable physical parameter not necessarily recognized by a patient; or enhancement or improvement of a condition, disorder or disease. Treatment includes inducing a clinically significant response without undue levels of side effects, such as avoiding significant exposure of healthy tissue to radiation. Treatment also includes extending the survival period as compared to the expected survival period if not receiving treatment.
[0030] As used herein, the term "contacting" means bringing two elements together in an in vitro or in vivo system, such as applying or adhering a composition provided herein to the skin of a subject, or implanting a composition into a cavity, organ, tissue, etc. within a subject.
[0031] As used herein, the term "comprising" (and any form of comprising, such as "comprise", "comprises", and "comprised"), "having" (and any form of having, such as "have" and "has"), "including" (and any form of including, such as "includes" and "include"), or "containing" (and any form of containing, such as "contains" and "contain") is inclusive or open-ended and does not exclude additional, unrecited elements or method steps.
[0032] As used herein, the term "cancer" refers to the onset or progression of a malignant tumor, as well as a wide range of pathological symptoms associated with metastasis. Examples include, but are not limited to, skin cancer. Examples of skin cancer include, but are not limited to, malignant melanoma (MM), basal cell carcinoma (BCC), and squamous cell carcinoma (SCC).
[0033] As used herein, the term "animal" includes, but is not limited to, humans and non-human vertebrates such as wild, captive, and domestic animals.
[0034] As used herein, the term "about" means that a numerical value is an approximation and that minor variations do not significantly affect the implementation of the embodiments of the present disclosure. When numerical limitations are used, unless otherwise indicated by the context, "about" means that the numerical value may vary by up to 10% and still remain within the scope of the embodiments of the present disclosure. In some embodiments, the numerical value may vary by up to 5% and still remain within the scope of the embodiments of the present disclosure.
[0035] In some embodiments, a curable composition is provided that can be used, for example, to treat a condition in a subject that requires radiation to be delivered to a specific tissue or other region on or within the subject.

[0036] In some embodiments, the curable composition includes a first composition comprising one or more monomers, a second composition comprising one or more oligomers, a third composition capable of creating free radicals; and a fourth composition comprising one or more radioisotopes. Without being bound by theory, the third composition promotes the polymerization and curing of the first and second compositions when free radicals are generated. Free radicals can be generated via any known method, and thus, the third composition can include any such components necessary for the generation of free radicals. In some embodiments, the free radicals are generated through a chemical reaction occurring within the third composition. In some embodiments, the free radicals are generated when the third composition is exposed to radiation. The radiation can be ultraviolet light, infrared light, thermal radiation, or any other form of radiation used to promote the curing / polymerization of the composition.

As another non-limiting example, the radioisotope can be detected by an image processing processor and located by the image processing processor. Thus, in some embodiments, the radioisotope is present in an amount sufficient to be detected and located by a portable frisker such as a Geiger counter. In some embodiments, the radioisotope is present in an amount sufficient to be detected and located by an image processing processor. In some embodiments, the radioisotope is present in an amount sufficient to deliver a therapeutic dose of radiation to a mammal.
[0038] In some embodiments, one or more radioisotopes are therapeutic radioisotopes, diagnostic radioisotopes, or combinations thereof. As used herein, "therapeutic radioisotope" is any radioisotope used to deliver a therapeutic radiation to a subject in need thereof for the treatment of a disease or disorder. As used herein, "diagnostic radioisotope" is any radioisotope used in combination with an imaging unit and an image processing processor to assist in the diagnosis of any disease or disorder. It should be understood that "therapeutic radioisotope" and "diagnostic radioisotope" are not mutually exclusive.
[0039] In some embodiments, one or more radioisotopes include diagnostic radioisotopes. In some embodiments, the diagnostic radioisotopes are present in an amount sufficient to be detected and located. Detection and location can be by any means known in the art. By way of non-limiting example, the radioisotope can be detected with a portable frisker or Geiger counter, and thus the radioisotope is located by reading the frisker or Geiger counter. As another non-limiting example, the radioisotope can be detected by an image processing processor and located by the image processing processor. Thus, in some embodiments, the radioisotope is present in an amount sufficient to be detected and located by a portable frisker such as a Geiger counter. In some embodiments, the radioisotope is present in an amount sufficient to be detected and located by an image processing processor. In some embodiments, the diagnostic radioisotopes are produced from one or more radioisotope precursors.

[0054] In some embodiments, one or more radioisotopes in the fourth composition are produced by activating one or more radioisotope precursors. As used herein, "activating" one or more radioisotope precursors or their "activation" refers to any process or method known in the art for producing a desired radioisotope from a given radioisotope precursor. For example, activation of a radioisotope precursor can include bombarding (exposing) the precursor with high energy particles. The particles that bombard can include, but are not limited to, alpha particles (α), neutrons (n), 3 He atoms, protons (p), tritons (t), gamma rays (γ), heavy ions, and deuterons (d). Typical sources of these types of bombardment are nuclear reactors and particle accelerators. Examples of precursor activation are: using a (p,n) reaction to 103 produce Pd: 103 Rh(p,n)→ 103 Pd, where "p" is proton incidence and "n" is neutron emission; using a (n,γ) reaction to 103 produce Pd: 102 Pd(n,γ)→ 103 Pd, where "n" is neutron incidence and "γ" is gamma ray emission; using a (p,2n) reaction to103 Generating Pd: 104 Pd(p,2n)→ 103 Ag(ε)→ 103 Pd, where "p" is proton incidence, "2n" is the emission of two neutrons, and "ε" is electron capture; using the (n,γ) reaction to 32 Generating P: 31 P(n,γ)→ 32 P, where "n" is neutron incidence and "γ" is gamma ray emission; using the (n,α) reaction to 7 Generating Li and α: 10 B(n,α)→ 7 Li, where "n" is neutron incidence and "α" is alpha emission; or using the (n,γ) reaction to 90 Generating Y: 89 Y(n,γ)→ 90 Y, where "n" is neutron incidence and "γ" is gamma ray emission, including but not limited to these. Additional reactions for precursor activation are (α,3n), (α,2n), (α,n), (p,γ), (d,n), ( 3 He,np), (α,np), (t,n), ( 3 He,p), (p,pn), (γ,n), (n,2n), (d,p), (t,np), (t,p), (p,α), (n,t), (γ,np), (n,nd), (n,d), (γ,p), (n,np), (n,p), (t, 3 He), (n,α), (n,n 3 He), (n, 3Including, but not limited to, (He), (p,3n), (p,4n), and (n,pd). In some embodiments, this is utilized by activating a precursor in the cured composition. For example, in some embodiments, the isotope-modified precursor is incorporated into a curable device and then cured. The cured device is then exposed to a sufficient flux of neutron radiation for a period sufficient to activate the precursor to a predetermined activity level. This activity can be determined to be sufficient for the purpose. In some embodiments, the activated device can then be applied to a patient to deliver a therapeutic dose of radioactive material to the area designed to be treated. In some embodiments, another isotope-modified precursor can be used and the same or a similar process can be used, but instead of neutron radiation, the device is exposed to a proton beam of sufficient energy and flux to activate the precursor to a predetermined activity level and is then used to treat a patient as described herein.

[0097] In some embodiments, a method of preparing a multilayer substantially cured composition or cured composition comprises preparing a first layer of a substantially cured composition or cured composition, including mixing a curable composition as provided herein and exposing the curable composition to radiation to form a first layer of a substantially cured composition or cured composition. In some embodiments, the method comprises preparing a second layer of a substantially cured composition or cured composition on the first layer, including mixing a curable composition as provided herein that includes a photoinitiator, disposing the mixture on the first layer, and exposing the mixture to radiation to form a second layer of a substantially cured composition or cured composition on the first layer. In some embodiments, the method comprises preparing a third layer of a substantially cured composition or cured composition on the second layer, including mixing a curable composition as provided herein that includes a photoinitiator, disposing the mixture on the second layer, and exposing the mixture to radiation to form a third layer of a substantially cured composition or cured composition on the first layer. As provided herein, this process can be repeated as many times as necessary to form a multilayer composition.
[0098] As provided herein, the curable composition of the present disclosure may contain radioisotopes or radioisotope precursors that are uniformly distributed throughout the composition, or may contain radioisotopes or radioisotope precursors with a non-uniform distribution. Thus, when creating a multi-layer substantially cured composition or cured composition by the method provided herein, in order to form a multi-layer substantially cured composition or cured composition, each layer may optionally omit the composition of the radioisotope or radioisotope precursor, and the radioisotope or radioisotope precursor of the multi-layer substantially cured composition or cured composition is such that one or more portions of the multi-layer substantially cured composition or cured composition contain a higher regional concentration of the radioisotope or radioisotope precursor than other regions of the multi-layer substantially cured composition or cured composition, spatially distributed. Such a multi-layer substantially cured composition or cured composition is useful, for example, for performing dosimetry of radiation that coincides with a particular treatment area.
[0099] Accordingly, in some embodiments, a method of preparing a multilayer substantially cured composition or cured composition comprises preparing a first layer of the substantially cured composition or cured composition, including mixing a curable composition as provided herein and exposing the curable composition to radiation to form a first layer of a substantially cured composition or cured composition; optionally mixing a curable composition comprising a photoinitiator as provided herein that does not contain a radioisotope or radioisotope precursor, disposing the mixture on the first layer, and exposing the mixture to radiation to form a second layer of a substantially cured composition or cured composition on the first layer; optionally mixing a curable composition comprising a photoinitiator as provided herein that does not contain a radioisotope or radioisotope precursor, disposing the mixture on the second layer, and exposing the mixture to radiation to form a third layer of a substantially cured composition or cured composition on the first layer, optionally including preparing a third layer of the substantially cured composition or cured composition on the second layer. As provided herein, this process can be repeated as many times as necessary to form a multilayer composition.
[0100] It should be understood that the methods described above are illustrative and are not intended to be limiting in any way. For example, the preparation of a substantially cured composition or a cured composition may include any necessary steps for initiating the process of curing or substantially curing the composition through the generation of free radicals in a third composition. In some embodiments, the free radicals are generated through a chemical reaction as provided herein. In some embodiments, the free radicals are generated when exposed to radiation as provided herein. It should also be understood that when fabricating a multi-layer substantially cured composition or a cured composition, each layer may not need to be exposed to an initiating catalyst (e.g., chemical reaction, radiation, etc.) to generate free radicals. Without being bound by any particular theory, the free radicals generated by the third composition initiate the process of curing or substantially curing the composition. Each successive layer may be exposed to an initiating catalyst (e.g., chemical reaction, radiation, etc.) to generate free radicals, or the free radicals generated during the process of curing or substantially curing the previous layer may themselves act as an initiating catalyst to cure or substantially cure the successive layer.
[0101] Thus, in some embodiments, a method of preparing a multilayer substantially cured composition or cured composition comprises preparing a first layer of a substantially cured composition or cured composition, including mixing a curable composition as provided herein and exposing the curable composition to radiation to form a first layer of a substantially cured composition or cured composition; preparing a second layer of a substantially cured composition or cured composition on the first layer, including mixing a curable composition as provided herein, optionally without a radioisotope or radioisotope precursor, disposing the mixture on the first layer, and optionally exposing the mixture to radiation, wherein free radicals generated during optional radiation or preparation of the previous layer initiate a process of forming a second layer of a substantially cured composition or cured composition on the first layer; and optionally preparing a third layer of a substantially cured composition or cured composition on the second layer, including mixing a curable composition as provided herein, optionally without a radioisotope or radioisotope precursor, disposing the mixture on the second layer, and optionally exposing the mixture to radiation, wherein free radicals generated during optional radiation or preparation of the previous layer initiate a process of forming a third layer of a substantially cured composition or cured composition on the first layer. As provided herein, this process can be repeated as many times as necessary to form a multilayer composition.
[0102] The compositions provided herein can also be prepared by additional processes, such as 3-D printing, to form compositions having specific three-dimensional structures or shapes. The shape can be based on the area being treated, such as a skin area or a lumen into which the composition is implanted.
[0103] Three-dimensional (3D or 3-D) printing is an additional printing process for creating three-dimensional objects from digital models. 3D printing technology is known as an additive process because it involves successive layers of material.
[0104] 3D printing technology is used in various industries with respect to manufacturing and planning. For example, the automotive, aerospace, and consumer goods industries use 3D printing to produce prototypes for parts and products. 3D printing is also used in the construction industry to print structural models. The use of 3D printing is also growing rapidly in civilian and government defense.
[0105] Therefore, 3-D printing can be used to create constructs (compositions) based on images of the area, cavity, surface, etc. of the subject to be treated. For example, conventional 3D printing enables the creation of an object by laminating materials one layer at a time on a flat manufacturing platform. After the first layer is laminated, the second layer is laminated, i.e., laminated on top of the first layer. This process is repeated as necessary to create a multi-layer solid article.
[0106] In some embodiments, a system is provided that includes a processor(s) configured to prepare a model of a construct (i.e., a cured composition or a substantially cured composition) manufactured by a 3-D printing system. The model construct can define, similar to the shape of the construct, the type(s) of material(s) included in the construct, and the location within the construct where each type of material is disposed. The shape of the construct can include a position-specific shape, such as a position-specific shape of a portion of the construct that mates with the subject or area of the subject to be treated. For example, a construct designed to mate with a portion of a subject having exposed skin or tissue is made using the compositions provided herein.
[0107] In some embodiments, the preparation of the model can include scanning an area of the subject (e.g., skin, tissue, cavity, etc.) from which the construct is to be obtained using a three-dimensional scanner. For example, a scanner is used to determine the topology of the area. The size or location of the construct is determined by scanning or through any other suitable means.
[0108] Alternatively or additionally, preparing the model may include downloading the model from a model repository or any other suitable source. The processor(s) may then fabricate a model of the construct based on the result.
[0109] In some embodiments, preparing the model of the construct is performed using off-the-shelf software, which may include software for “standard” scans, modeling, and / or printing. For example, common 3D model file formats are used to create tissue constructs in common 3D modeling and printing software.
[0110] In some embodiments, the area to be irradiated is determined by creating a dermoscopic image, which is then converted to a 3-D image and used to manufacture a construct through 3-D printing such that the area to be irradiated is specifically irradiated and healthy tissue is not substantially affected by the radiation. Other systems can be used to create 3-D images, which can then be used to fabricate constructs of appropriate size or positional specificity.
[0111] Accordingly, in some embodiments, a method of preparing a substantially cured composition or a cured composition is provided. In some embodiments, the method includes mixing a curable composition as provided herein, printing the composition with a 3-D printer into the three-dimensional structure of a target region, and exposing the composition to radiation to form a substantially cured composition or a cured composition in the shape or site-specificity of the three-dimensional structure of the target region. In some embodiments, the third composition of the curable composition includes a photoinitiator as provided herein. In some embodiments, the three-dimensional structure of the presented target region is prepared from the region of the subject to be treated using the cured composition. In some embodiments, the target region is the skin surface to be treated. In some embodiments, the target region is a bone, tissue, cavity, etc. of the subject. In some embodiments, the three-dimensional structure of the target region is determined by imaging the region of the subject to be treated using the cured composition and forming the dimensions / boundaries of the three-dimensional structure of the target region.
[0112] In some embodiments, a method of treating a subject using radiation is provided. In some embodiments, the method includes applying, implanting, contacting, etc., a cured composition or a substantially cured composition as provided herein onto or into the target region of the subject, or with the target region of the subject. In some embodiments, the target region is the skin surface to be treated. In some embodiments, the target region is a bone, tissue, cavity, etc. of the subject.
[0113] In some embodiments, a method of treating a subject having cancer is provided. In some embodiments, the method includes applying, implanting, contacting, etc., a cured composition or a substantially cured composition as provided herein onto or into the target area of the subject or together with the target area of the subject. In some embodiments, the target area is the skin surface to be treated. In some embodiments, the target area is the bone, tissue, cavity, etc. of the subject. In some embodiments, the cancer is skin cancer. In some embodiments, the skin cancer is malignant melanoma (MM), basal cell carcinoma (BCC) or squamous cell carcinoma (SCC). In some embodiments, the skin cancer is MM. The cured composition or the substantially cured composition can be prepared by the methods provided herein.
