DETAILED DESCRIPTION OF THE INVENTION

[0012] CD73 is a glycosylphosphatidylinositol (GPI) anchored cell surface protein that catalyzes the hydrolysis of AMP to adenosine, and works in concert with CD39, which converts ATP into AMP. The resulting adenosine functions as a signaling molecule that activates the PI receptors expressed on the cell surface in many different tissues. Four G protein-coupled PI or adenosine receptors have been cloned and designated as Al, A2A, A2B, and A3. Adenosine impacts a wide range of physiological processes including neural function, vascular perfusion, and immune responses. In doing so, this metabolite regulates CNS, cardiovascular, and immune system functions, to name a few.

[0013] Increasing evidence suggests that interactions between tumor cells and their microenvironment are essential for tumorigenesis. The purinergic signaling pathway in which CD73 plays a critical role, has emerged as an important player in cancer progression. It has become clear in recent years that adenosine is one of the most important immunosuppressive regulatory molecules in the tumor microenvironment, and contributes to immune escape and tumor progression.

[0014] CD73 is a key protein molecule in cancer development. CD73 has been found to be overexpressed in many cancer cell lines and tumor types including, for example, breast cancer, colorectal cancer, ovarian cancer, gastric cancer, gallbladder cancer, and cancers associated with poor prognosis.

[0015] The expression of CD73 in tumors is regulated by a variety of mechanisms. CD73 expression is negatively regulated by estrogen receptor (ER) in breast cancer. Thus, CD73 is highly expressed in ER negative breast cancer patients. The hypoxia-inducible factor- la (HIF-la) has also been shown to regulate CD73 transcription. Additionally, inflammatory factors such as IFN-γ affect CD73 levels. CD73 expression is also epigenetically regulated by CpG island methylation in cell lines and clinical tumor samples. [0016] In addition to being a prognostic biomarker in cancer patients, overexpression of CD73 has also been found to be functionally linked to therapy resistance. Elevated levels of CD73 were initially linked to resistance to a variety of chemotherapeutic agents including vincristine and doxorubicin.

[0017] CD73 has also been shown to be involved in immunotherapy resistance. This ectonucleotidase participates in the process of tumor immune escape by inhibiting the activation, clonal expansion, and homing of tumor-specific T cells (in particular, T helper and cytotoxic T cells); impairing tumor cell killing by cytolytic effector T lymphocytes; driving, via pericellular generation of adenosine, the suppressive capabilities of Treg and Thl7 cells; enhancing the conversion of type 1 macrophages into tumor-promoting type 2 macrophages; and promoting the accumulation of MDSCs.

[0018] Small molecular inhibitors and monoclonal antibodies targeting CD73 have shown anti-tumor activity in a variety of immune-competent but not in immune-deficient mouse tumor models. Overall, these studies suggest that anti-CD73 therapy activity is dependent on its ability to elicit immune responses in vivo.

[0019] Antibodies which block PD-1, PD-L1, and CTLA-4 have shown impressive objective response in cancer patients. Recent data demonstrates that anti-CD73 mAb significantly enhances the activity of both anti-CTLA-4 and anti-PD-1 mAbs in several mouse tumor models. In addition to checkpoint blockade, CD73-mediated production of adenosine could contribute to resistance to additional immunotherapy modalities including CAR-T cells and cancer vaccines.

[0020] Interfering with CD73 activity represents a strategy to re-sensitize tumors to therapy. Based on the link between CD73 and therapy resistance, combining anti-CD73 treatment with chemotherapy or immunotherapy is an effective approach to enhance their activity in cancer patients with high CD73 levels. In some instances, CD73 expression serves as a biomarker to identify patients that could benefit from anti- CD73 combination therapy.

[0021] In some instances, the CD39/CD73 couple turns ATP -driven pro-inflammatory cell activity toward an adenosine-mediated anti-inflammatory state. A number of studies have shown changes in the activity of the CD39/CD73 axis during infections induced by a variety of microorganisms. An increase in CD73 expression has also been observed in the brain of mice infected with Toxoplasma gondii, which promotes the parasite life cycle through the production of adenosine. Thus, the pharmacological blockade of CD73 is a promising therapeutic approach to treat human toxoplasmosis.

[0022] Enhanced expression and activity of CD39 and CD73 have been observed in endothelial cells infected with cytomegalovirus (CMV). The increase in local adenosine production, associated with the upregulation of ecto-nucleotidases, generates an immunosuppressive and antithrombotic microenvironment, which facilitates viral entry into target cells.

[0023] In some instances, inhibitors of CD73, by driving a decrease on adenosine production, have applications as antiviral agents. The elevated expression/activity of CD39 and CD73 on lymphocytes of individuals infected with human immunodeficiency virus (HIV) indicates a role for ecto-nucleotidases in the immune dysfunction associated with this disease. In fact, an increased proportion of Tregs expressing CD39, as well as a positive correlation between CD39 expression on Tregs and disease progression has been observed in different cohorts of HIV-infected patients. It has also been shown that HIV-positive patients had a higher number of CD39+ Treg, and that their Teff exhibited an increased sensitivity in vitro to the suppressive effect of adenosine, which was related to the elevated expression of immunosuppressive A2A receptors.

[0024] In the central nervous system, adenosine plays a critical role in controlling a multitude of neural functions. Through the activation of PI receptors, adenosine is involved in diverse physiological and pathological processes such as regulation of sleep, general arousal state and activity, local neuronal excitability, and coupling of the cerebral blood flow to the energy demand. In some instances, manipulation of adenosine production via CD73 inhibitors is useful for treating neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease and Huntington's disease, and psychiatric disorders such as schizophrenia and autism.

Accordingly, when the terms "inhibition" or "suppression" are applied to describe, e.g., an effect on the enzymatic activity of CD73, the term refers to the ability of a compound disclosed herein to statistically significantly decrease the 5 '-nucleotidase activity of CD73 (catabolizing the hydrolysis of adenosine monophosphate, AMP, to adenosine), relative to the CD73 -mediated 5 '-nucleotidase activity in an untreated (control) cell. In some instances, the cell which expresses CD73 is a naturally occurring cell or cell line (e.g., a cancer cell) or is recombinantly produced by introducing a nucleic acid encoding CD73 into a host cell. In some aspects, compounds disclosed herein statistically significantly decrease the 5 '-nucleotidase activity of a soluble form of CD73 in a biological fluid. In one aspect, the compound disclosed herein inhibit CD73- mediated 5 '-nucleotidase activity by at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or about 100%, as determined, for example, by the methods described in the Examples and/or methods known in the art.

[0042] As used herein, "treatment" or "treating," or "palliating" or "ameliorating" are used interchangeably.

These terms refer to an approach for obtaining beneficial or desired results including but not limited to therapeutic benefit and/or a prophylactic benefit. By "therapeutic benefit" is meant eradication or amelioration of the underlying disorder being treated. Also, a therapeutic benefit is achieved with the eradication or amelioration of one or more of the physiological symptoms associated with the underlying disorder such that an improvement is observed in the patient, notwithstanding that the patient is still afflicted with the underlying disorder. For prophylactic benefit, the compositions are, in some embodiments, administered to a patient at risk of developing a particular disease, or to a patient reporting one or more of the physiological symptoms of a disease, even though a diagnosis of this disease has not been made.

In some embodiments, the compound disclosed herein is combined with a pharmaceutically suitable or acceptable carrier (also referred to herein as a pharmaceutically suitable (or acceptable) excipient, physiologically suitable (or acceptable) excipient, or physiologically suitable (or acceptable) carrier) selected on the basis of a chosen route of administration and standard pharmaceutical practice as described, for example, in Remington: The Science and Practice of Pharmacy (Gennaro, 21 ^st Ed. Mack Pub. Co., Easton, PA (2005)).

[00319] Accordingly, provided herein is a pharmaceutical composition comprising at least one compound disclosed herein, or a pharmaceutically acceptable salt, solvate, or steroisomer thereof, together with one or more pharmaceutically acceptable carriers. The carrier(s) (or excipient(s)) is acceptable or suitable if the carrier is compatible with the other ingredients of the composition and not deleterious to the recipient (i.e., the subject) of the composition.

[00320] One embodiment provides a pharmaceutical composition comprising a pharmaceutically acceptable excipient and a compound disclosed herein, or a pharmaceutically acceptable salt, solvate, or steroisomer thereof.

[00321] In certain embodiments, the compound disclosed herein is substantially pure, in that it contains less than about 5%, or less than about 1%, or less than about 0.1%, of other organic small molecules, such as unreacted intermediates or synthesis by-products that are created, for example, in one or more of the steps of a synthesis method.

[00322] Pharmaceutical compositions are administered in a manner appropriate to the disease to be treated (or prevented). An appropriate dose and a suitable duration and frequency of administration will be determined by such factors as the condition of the patient, the type and severity of the patient's disease, the particular form of the active ingredient, and the method of administration. In general, an appropriate dose and treatment regimen provides the composition(s) in an amount sufficient to provide therapeutic and/or prophylactic benefit (e.g., an improved clinical outcome, such as more frequent complete or partial remissions, or longer disease-free and/or overall survival, or a lessening of symptom severity. Optimal doses are generally determined using experimental models and/or clinical trials. The optimal dose depends upon the body mass, weight, or blood volume of the patient.

[00323] Oral doses typically range from about 1.0 mg to about 1000 mg, one to four times, or more, per day.

Methods of Treatment

[00324] The compounds disclosed herein, or a pharmaceutically acceptable salt, solvate, or steroisomer thereof, are useful as inhibitors of CD73 and, therefore, useful in the treatment of diseases or disorders in which it is believed CD73 activity plays a role.

Infections

[00334] A number of studies have shown changes in the activity of the CD39/CD73 axis during infections induced by a variety of microorganisms. One embodiment provides a method of treating an infection in a subject in need thereof, comprising administering to the subject a compound of disclosed herein, or a pharmaceutically acceptable salt, solvate, or stereoisomer thereof.

[00335] In some embodiments, the infection is a viral infection, a bacterial infection, or a parasitic infection.

Parasitic infections

[00336] In some embodiments, the infection is a parasitic infection. In some embodiments, the parasitic infection is caused by infection of the subject with a protozoan organism. In some embodiments, the protozoan organism selected from the group consisting of the genera Acanthamoeba, Babesia, Balantidium, Cryptosporidium, Dientamoeba, Eimeria, Entamoeba, Giardia, Isospora, Leishmania, Naegleria, Neospora, Plasmodium, Sarcocystis, Theileria, Toxoplasma, Trichomonas, Trypanosoma, or any combinations thereof. In some embodiments, the parasitic infection is caused by an infection with Toxoplasma gondii (T. gondii). In some embodiments, the parasitic infection is toxoplasmosis. In some embodiments, the toxoplasmosis is acute toxoplasmosis, latent toxoplasmosis, or cutaneous toxoplasmosis.

[00337] Acute toxoplasmosis: acute toxoplasmosis is often asymptomatic in healthy adults. However, symptoms may manifest and are often influenza-like: swollen lymph nodes, headaches, fever, fatigue, or muscle aches and pains that last for a month or more. Rarely will a human with a fully functioning immune system develop severe symptoms following infection. People with weakened immune systems are likely to experience headache, confusion, poor coordination, seizures, lung problems that may resemble tuberculosis or Pneumocystis jiroveci pneumonia (a common opportunistic infection that occurs in people with AIDS), or blurred vision caused by severe inflammation of the retina (ocular toxoplasmosis). Young children and immunocompromised people, such as those with HIV/AIDS, those taking certain types of chemotherapy, or those who have recently received an organ transplant, may develop severe toxoplasmosis. In some instances, toxoplasmosis causes damage to the brain (encephalitis) or the eyes (necrotizing retinochoroiditis). Infants infected via placental transmission may be born with either of these problems, or with nasal malformations, although these complications are rare in newborns. The toxoplasmic trophozoites causing acute toxoplasmosis are referred to as tachyzoites, and are typically found in bodily fluids.

[00338] Latent toxoplasmosis: due to its asymptomatic nature, it is easy for a host to become infected with Toxoplasma gondii and develop toxoplasmosis without knowing it. Although mild, flu-like symptoms occasionally occur during the first few weeks following exposure, infection with T. gondii produces no readily observable symptoms in healthy human adults. In most immunocompetent people, the infection enters a latent phase, during which only bradyzoites (tissue cysts) are present; these tissue cysts and even lesions can occur in the retinas, alveolar lining of the lungs (where an acute infection may mimic a

Pneumocystis jirovecii infection), heart, skeletal muscle, and the central nervous system (CNS), including the brain. Cysts form in the CNS (brain tissue) upon infection with T. gondii and persist for the lifetime of the host. Most infants who are infected while in the womb have no symptoms at birth, but may develop symptoms later in life.

[00339] Cutaneous toxoplasmosis: in some embodiments, skin lesions occur in the acquired form of the disease, including roseola and erythema multiforme-like eruptions, prurigo-like nodules, urticaria, and maculopapular lesions. Newborns may have punctate macules or ecchymoses. Diagnosis of cutaneous toxoplasmosis is based on the tachyzoite form of T. gondii being found in the epidermis.

Viral Infections

[00340] In some embodiments, the infection is a viral infection. In certain embodiments, the viral infection treatable with the methods provided herein includes, but is not limited to, chickenpox, the flu (influenza), herpes, human immunodeficiency virus (HIV/AIDS), human papillomavirus (HPV), Infectious

mononucleosis, mumps, measles, rubella, shingles, viral gastroenteritis (stomach flu), viral hepatitis, viral meningitis, and viral pneumonia.

Neurodegenerative diseases

[00341] In the central nervous system, adenosine plays a critical role in controlling a multitude of neural functions. Through the activation of PI receptors, adenosine is involved in diverse physiological and pathological processes such as regulation of sleep, general arousal state and activity, local neuronal excitability, and coupling of the cerebral blood flow to the energy demand. In some embodiments, the manipulation of adenosine production via CD73 inhibitors has therapeutic potential in neurodegenerative diseases. One embodiment provides a method of treating a neurodegenerative disease in a subject in need thereof, comprising administering to the subject a compound of disclosed herein, or a pharmaceutically acceptable salt, solvate, or stereoisomer thereof. In certain embodiments, the neurodegenerative disease treatable with the methods provided herein includes, but is not limited to, Alzheimer's disease, Parkinson's disease, and Huntington's disease. One embodiment provides a method of treating a psychiatric disorder in a subject in need thereof, comprising administering to the subject a compound of disclosed herein, or a pharmaceutically acceptable salt, solvate, or stereoisomer thereof. In some embodiments, the psychiatric disorder is schizophrenia or autism. Combination Therapy

[00342] In certain instances, the compound disclosed herein, or a pharmaceutically acceptable salt, solvate, or steroisomer thereof, is administered in combination with a second therapeutic agent.

[00343] In some embodiments, the benefit experienced by a patient is increased by administering one of the compounds described herein with a second therapeutic agent (which also includes a therapeutic regimen) that also has therapeutic benefit.

[00344] In one specific embodiment, a compound disclosed herein, or a pharmaceutically acceptable salt, solvate, or steroisomer thereof, is co-administered with a second therapeutic agent, wherein the compound disclosed herein, or a pharmaceutically acceptable salt, solvate, or steroisomer thereof, and the second therapeutic agent modulate different aspects of the disease, disorder or condition being treated, thereby providing a greater overall benefit than administration of either therapeutic agent alone.

[00345] In any case, regardless of the disease, disorder or condition being treated, the overall benefit experienced by the patient is simply additive of the two therapeutic agents or the patient experiences a synergistic benefit.

[00346] In certain embodiments, different therapeutically-effective dosages of the compounds disclosed herein will be utilized in formulating a pharmaceutical composition and/or in treatment regimens when the compounds disclosed herein are administered in combination with a second therapeutic agent. Therapeutically-effective dosages of drugs and other agents for use in combination treatment regimens are optionally determined by means similar to those set forth hereinabove for the actives themselves.

Furthermore, the methods of prevention/treatment described herein encompasses the use of metronomic dosing, i.e., providing more frequent, lower doses in order to minimize toxic side effects. In some embodiments, a combination treatment regimen encompasses treatment regimens in which administration of a compound disclosed herein, or a pharmaceutically acceptable salt, solvate, or steroisomer thereof, is initiated prior to, during, or after treatment with a second agent described herein, and continues until any time during treatment with the second agent or after termination of treatment with the second agent. It also includes treatments in which a compound disclosed herein, or a pharmaceutically acceptable salt, solvate, or steroisomer thereof, and the second agent being used in combination are administered simultaneously or at different times and/or at decreasing or increasing intervals during the treatment period. Combination treatment further includes periodic treatments that start and stop at various times to assist with the clinical management of the patient.

[00347] It is understood that the dosage regimen to treat, prevent, or ameliorate the condition(s) for which relief is sought, is modified in accordance with a variety of factors (e.g., the disease, disorder or condition from which the subject suffers; the age, weight, sex, diet, and medical condition of the subject). Thus, in some instances, the dosage regimen actually employed varies and, in some embodiments, deviates from the dosage regimens set forth herein.

[00348] For combination therapies described herein, dosages of the co-administered compounds vary depending on the type of co-drug employed, on the specific drug employed, on the disease or condition being treated, and so forth. In additional embodiments, when co-administered with a second therapeutic agent, the compound provided herein is administered either simultaneously with the second therapeutic agent, or sequentially.

[00349] In combination therapies, the multiple therapeutic agents (one of which is one of the compounds described herein) are administered in any order or even simultaneously. If administration is simultaneous, the multiple therapeutic agents are, by way of example only, provided in a single, unified form, or in multiple forms (e.g., as a single pill or as two separate pills).

[00350] The compounds disclosed herein, or a pharmaceutically acceptable salt, solvate, or steroisomer thereof, as well as combination therapies, are administered before, during or after the occurrence of a disease or condition, and the timing of administering the composition containing a compound varies. Thus, in one embodiment, the compounds described herein are used as a prophylactic and are administered continuously to subjects with a propensity to develop conditions or diseases in order to prevent the occurrence of the disease or condition. In another embodiment, the compounds and compositions are administered to a subject during or as soon as possible after the onset of the symptoms. In specific embodiments, a compound described herein is administered as soon as is practicable after the onset of a disease or condition is detected or suspected, and for a length of time necessary for the treatment of the disease. In some embodiments, the length required for treatment varies, and the treatment length is adjusted to suit the specific needs of each subject. For example, in specific embodiments, a compound described herein or a formulation containing the compound is administered for at least 2 weeks, about 1 month to about 5 years.

[00351] In certain embodiments, the second therapeutic agent is an adjuvant. In certain

embodiments, the second therapeutic agent is an anti-cancer agent. In certain embodiments, the second therapeutic agent is an antiemetic. In certain embodiments, the second therapeutic agent is an anti-infective agent. In certain embodiments, the second therapeutic agent is an antiviral agent. In certain embodiments, the second therapeutic agent is an antibacterial agent.

[00352] In some embodiments, the compound disclosed herein, or a pharmaceutically acceptable salt, solvate, or steroisomer thereof, is administered in combination with an adjuvant. In one embodiment, the therapeutic effectiveness of one of the compounds described herein is enhanced by administration of an adjuvant (i.e., by itself the adjuvant has minimal therapeutic benefit, but in combination with another therapeutic agent, the overall therapeutic benefit to the patient is enhanced).

In some embodiments, the compound disclosed herein, or a pharmaceutically acceptable salt, solvate, or steroisomer thereof, is administered in combination with an anti -cancer agent.

[00353] In some embodiments, the anti-cancer agent is a hormone blocking therapy. Hormone blocking therapy includes the use of agents that block the production of estrogens or block the estrogen receptors. In some embodiments, hormone blocking therapy includes the use of estrogen receptor modulators and/aromatase inhibitors. Estrogen receptor modulators include triphenylethylene derivatives

(e.g., tamoxifen, toremifene, droloxifene, 3-hydroxytamoxifen, idoxifene, TAT-59 (a phosphorylated derivative of 4-hydroxytamoxifen) and GW5638 (a carboxylic acid derivative of tamoxifen)); non-steroidal estrogen receptor modulators (e.g., raloxifene, LY353381 (SERM3) and LY357489); steroidal estrogen receptor modulators (e.g., ICI-182,780). Aromatase inhibitors include steroidal aromatase inhibitors and non-steroidal aromatase inhibitors. Steroidal aromatase inhibitors include, but are not limited to, exemestane. Non-steroidal aromatase inhibitors include, but are not limited to, anastrozole and letrozole.
