Description

[Technical Field]

[0001] The compositions, compounds, and methods disclosed herein relate to the general fields of organ transplantation, organ protection, organ preparation, and organ preservation. [Background technology]

[0002] Organ transplantation, in which a damaged or diseased organ is replaced with a relatively healthy organ from a donor, is the only available treatment for end-stage organ failure. The most commonly transplanted organs are the kidneys, followed by the liver, heart, and lungs. Pancreatic, intestinal, and multi-organ transplants are also performed, but far less frequently. Overall, more than 36,000 organ transplants were performed in the United States alone in 2018. However, due to a shortage of suitable donor organs, the number of people in the United States who need organ transplants now exceeds 113,000 as of April 2019 (data from the United Network for Organ Sharing).

[0003] Aside from a shortage of donor organs, a central challenge in organ transplantation is the rejection of transplanted organs by the recipient's immune system. For some organs, approximately one-quarter to half of transplants fail within five years (data from the U.S. Organ Sharing Network, April 17, 2019). To prevent potential organ rejection, organ recipients often undergo long-term treatment with immunosuppressants, which further endangers their health by increasing their susceptibility to infections and certain types of cancer. These immunosuppressive treatments also carry other potentially serious side effects.

[0004] Graft rejection is classified into three main types, each with a different timescale and underlying mechanism. These three main types are hyperacute rejection, acute rejection, and chronic rejection. Hyperacute rejection occurs when pre-existing antibodies against the transplanted organ are present and can manifest within minutes of transplantation. However, hyperacute rejection is rarely encountered due to the conventional pre-screening of recipients for anti-donor antibodies.

[0005] Acute rejection occurs within the first few months after transplantation. It occurs when the recipient's immune system reacts to antigens on the surface of donor organ cells (primarily antigens of the major histocompatibility complex, MHC). The resulting inflammatory process ultimately leads to necrosis of the graft tissue.

[0006] Chronic rejection occurs months or years after transplantation. It is characterized by multiple vascular conditions, including atherosclerosis and progressive stenosis of the transplanted vessels (transplant vascular disease), often accompanied by fibrosis within the parenchyma of the transplanted organ. The resulting ischemia often leads to necrosis of the transplanted tissue and eventual organ failure. Immunosuppressant treatment of organ recipients appears to have little effect on chronic rejection.

[0007] In addition to the close antigenic compatibility between donor and recipient, the condition of the donor organ at the time of transplantation is considered to have a major influence on both acute and chronic rejection. Organs from living donors generally have a better survival rate (US Organ Sharing Network). However, currently, more than 80% of all organs originate from deceased donors (US Organ Sharing Network). Processes occurring both after donor death and during organ retrieval and handling before transplantation can potentially affect the recipient's immune response.

[0008] Organ donors who are brain dead are generally preferred over those who are cardiac dead because blood continues to be injected into the organs until the moment of retrieval. However, brain death has been shown to produce a significant long-term systemic inflammatory response that can damage potential donor organs. Recent evidence suggests that these inflammatory processes have a negative impact on transplant outcomes, and that targeting inflammatory factors produced after brain death in pre-transplant donors is a potential strategy to improve transplant success rates.

[0009] Organs harvested for transplantation are also susceptible to damage from ischemia-reperfusion injury. After retrieval from a donor, organs are typically maintained under cryogenic storage in preservation solutions. Ischemia-reperfusion injury occurs when the blood supply to an organ is removed, and then restored after the organ is placed in the transplant recipient. Ischemia-reperfusion injury appears to influence both acute and chronic rejection in kidney transplants. [Overview of the Initiative]

Therefore, to explain a reference to a range, for example, 1-10, 10-20, 20-30, 30-40, 40-50, 50-60, 60-75, 75-100, 100-150, 150-200, 200-250, 250-300, 300-400, 400-500, 500-750, 750-1,000, 1,000-1,500, 1,500-2,000, 2,000-2,500 The ranges 2,500-3,000, 3,000-3,500, 3,500-4,000, 4,000-4,500, 4,500-5,000, 5,500-6,000, 6,000-7,000, 7,000-8,000, or 8,000-9,000 include ranges such as 10-50, 50-100, 100-1,000, 1,000-3,000, and 2,000-4,000.

[0188] Modifications can be made to the foregoing without departing from the basic aspects of the present technology. Although the present technology is described in great detail with reference to one or more specific embodiments, those skilled in the art will recognize that modifications can be made to the embodiments specifically disclosed herein, and that these modifications and improvements fall within the scope and spirit of the present technology.

[0189] Some embodiments of the Art described herein can preferably be carried out in the absence of elements not specifically disclosed herein. Accordingly, in some embodiments, the terms “comprising” or “comprises” can be replaced with “consisting essentially of” or “consisting of” or their grammatical variations. The terms “a” or “an” can refer to one or more elements that they modify unless it is clearly stated in the context that one or more elements are being described (for example, “a reagent” may mean one or more reagents). The term “about” as used herein refers to a value within 10% (i.e., plus or minus 10%) of an underlying parameter, and the use of the term “about” at the beginning of a string of values ​​modifies each value (i.e., “about 1, 2 and 3” refers to about 1, about 2 and about 3). For example, a weight of “about 100 grams” may include weights between 90 grams and 110 grams. As used herein, the term “substantially” refers to value modifiers meaning “at least 95%”, “at least 96%”, “at least 97%”, “at least 98%”, or “at least 99%”, and may include 100%. For example, a composition that is substantially free of X may contain less than 5%, less than 4%, less than 3%, less than 2%, or less than 1% of X, and / or X may not be present or detectable in the composition.
