USE OF IODIDE COMPOUNDS FOR THE TREATMENT AND PREVENTION OF CHEMOTHERAPY-ASSOCIATED CACHEXIA AND CARDIOTOXICITY

Abstract
The present invention relates to the use of iodide compounds, to treat and prevent cachexia and cardiotoxicity resulting from treatment with an anti-cancer therapy.
Description
FIELD OF THE INVENTION

This disclosure relates to methods of using iodide, e.g., sodium iodide, for treating or preventing chemotherapy-associated cachexia and cardiotoxicity.


BACKGROUND OF THE INVENTION

Cachexia is a complex syndrome associated with underlying illness causing ongoing muscle loss. A range of diseases can cause cachexia, most commonly cancer, congestive heart failure, chronic obstructive pulmonary disease, chronic kidney disease, chronic liver disease and AIDS. In addition, medical treatments, such as chemotherapeutic agents, can cause cachexia. Cachexia can be very serious and may complicate treatment for the condition that caused it and lower the response to treatment. For example, patients with cancer who have cachexia are less able to tolerate chemotherapy and other therapies. As a result of these complications, patients with cachexia have a lower quality of life and a worse clinical outlook.


There are three main categories of cachexia. Precachexia is defined as a loss of up to 5 percent of body weight while not trying to lose weight and having a known illness or disease. Cachexia is a loss of more than 5 percent of body weight over 12 months or less, while not trying to lose weight and having a known illness or disease. Several other criteria include loss of muscle strength, decreased appetite, fatigue, and inflammation. Refractory cachexia applies to individuals with cancer, and includes weight loss, muscle loss, loss of function, plus a failure to respond to cancer treatment. In some instances, cachexia is associated with a loss of cardiac muscle tissue, loss of skeletal muscle tissue, and/or loss of fat. These can result in loss of strength and reduced cardiac function. Thus, agents that cause cachexia can result in cardiotoxicity.


Like cachexia, cardiotoxicity is also a serious adverse effect of cancer treatment, including treatment with a variety of chemotherapeutic agents, such as anthracyclines, fluorouracil, taxanes, monoclonal antibodies, and tyrosine kinase inhibitors. Different types of cardiotoxicity include reversible (type 2), irreversible (type 1), acute, chronic, and late-onset. Cardiotoxicity may be defined into four categories: 1) directed cytotoxic effects of chemotherapy and associated cardiac dysfunction (associated with, e.g., alkylating agents, anthracyclines, interferon alpha, monoclonal antibodies, tyrosine kinase inhibitors); 2) cardiac ischemia (associated with, e.g., antitumor antibiotics, fluorouracil, topoisomerase inhibitors); 3) cardiac arrhythmias (associated with, e.g., anthracyclines, other agents); and 4) pericarditis (associated with, e.g., bleomycin, cyclophosphomide, cytarabine). Cardiotoxicity may result in cardiac dysfunction, which may be determined based on clinical symptoms or use of echocardiogram or electrocardiogram (EKG).


There is clearly an unmet need for specific treatments to treat or reverse cachexia and cardiotoxicity, including cachexia and cardiotoxicity associated with cancer treatments. The present disclosure addresses this need.

In certain embodiments, the cancer therapy is treatment with an anthracycline antibiotic, e.g., doxorubicin, and the cancer being treated is a leukemia, lymphoma, breast cancer, prostate cancer, ovarian cancer, or lung cancer, and treatment with iodide treats, inhibits, or reduces the severity of cachexia. In certain embodiments, the cancer therapy is treatment with an anthracycline antibiotic, e.g., doxorubicin, alone or in combination with cyclophosphamide, trastuzumab and/or paclitaxel, and the cancer being treated is a breast cancer, sarcoma, lymphoma, or leukemias, and treatment with iodide treats, inhibits, or reduces the severity of cardiotoxicity. In certain embodiments, the cancer therapy is treatment with an alkylating agent, e.g., cyclophosphamide, and the cancer being treated is a lymphoma, leukemia, or myeloma (e.g., multiple myeloma), and treatment with iodide treats, inhibits, or reduces the severity of cardiotoxicity. In certain embodiments, the cancer therapy is treatment with an inhibitor of microtubule polymerization, e.g., paclitaxel, and the cancer being treated is a breast cancer or a lung cancer, and treatment with iodide treats, inhibits, or reduces the severity of cardiotoxicity. In certain embodiments, the cancer therapy is treatment with a monoclonal antibody, e.g., trastuzumab, and the cancer being treated is a breast cancer or a gastric cancer, and treatment with iodide treats, inhibits, or reduces the severity of cardiotoxicity. In some embodiments, the subject is provided with the iodide compound, e.g., NaI, via repeat daily doses of about 1 mg/kg or 2 mg/kg for several days, e.g., about 3 days, about 4 days, about 5 days, or about 1 week, or for the duration of treatment with the cancer therapy.


In certain embodiments, the subject is provided with the iodide before the cancer therapy and/or during an overlapping time period with the cancer therapy. For example, the subject may be provided with a bolus dose of NaI before undergoing radiation therapy or a chemotherapeutic treatment, such as an intravenous infusion. In addition, or instead, the subject may be provided with NaI over the course of the treatment. In particular embodiments, the subject is provided with 0.5 mg/kg-5 mg/kg (e.g., 1 mg/kg or 2 mg/kg) of iodide, e.g., NaI, daily for the duration of the cancer therapy. In particular embodiments, the iodide, e.g., sodium iodide is provided to the subject as a bolus or via an osmotic pump, e.g., as disclosed in the accompanying examples. In certain embodiments, the subject is provided with an intravenous bolus between one hour up to one minute prior to administration of the cancer therapy.


In particular embodiments, treatment with the NaI results in reduced cachexia resulting from the cancer therapy, which may be demonstrated in a variety of ways, such as, e.g., reduced total weight loss, reduced liver weight loss, reduced heart weight loss, or reduced muscle weight loss. In particular embodiments, reduced cachexia is evidenced as a total weight loss of less than 10% or less than 5% as compared to the subject's baseline total weight before treatment with the cancer therapy. In certain embodiments, the cancer therapy is treatment with an anthracycline antibiotic, e.g., doxorubicin, and the cancer being treated is a leukemia, lymphoma, breast cancer, prostate cancer, ovarian cancer, or lung cancer. In some embodiments, treatment with NaI reduces loss of skeletal muscle and/or cardiac muscle following the cancer therapy, e.g., chemotherapy or radiation therapy. In particular examples, the cancer therapy is treatment with an anthracycline antibiotic, such as doxorubicin, or cisplatin. In particular embodiments, the iodide, e.g., sodium iodide is provided to the subject as a bolus or via an osmotic pump, e.g., as disclosed in the accompanying examples. In particular examples, the cancer therapy is treatment with an anthracycline antibiotic, such as doxorubicin, or cisplatin.


In particular embodiments, treatment with the NaI results in reduced cardiotoxicity resulting from the cancer therapy, which may be demonstrated in a variety of ways, such as by less of a decline or no decline in systolic function as quantified through measurement of left ventricular ejection fraction (LVEF), e.g., a reduced or lessened LVEF) reduction. In particular embodiments, treatment with the NaI results in the treated subject's LVEF either not decreasing or decreasing less than 10 percentage points from baseline. In certain embodiments, a LVEF) reduction of less than 10% or less than 5% as compared to a normal range or the subject's baseline prior to treatment with the cancer therapy is an indication of reduced cardiotoxicity. In certain embodiments, reduced cardiotoxicity may be demonstrated via echocardiographic measurement of global longitudinal strain (GLS). Global systolic longitudinal myocardial strain (GLS) on echocardiography has emerged as a reproducible indicator of early anthracycline-related myocardial dysfunction and future reduction in LVEF. A fall in GLS of 15% compared with baseline measurement is considered pathological and an early injury marker. In particular embodiments, treatment with the NaI results in the treated subject's GLS either not decreasing or decreasing less than 15%, e.g., less than 10% or less than 5% from baseline. In certain embodiments, a GSL reduction of less than 15% or 10% or less than 5% as compared to a normal range or the subject's baseline prior to treatment with the cancer therapy is an indication of reduced cardiotoxicity. Reduced cardiotoxicity may also be measured as less cardiac dysfunction, which may be determined based on clinical symptoms or the use of echocardiogram or electrocardiogram (EKG). In particular examples, the cardiotoxicity is type 1, and the cancer therapy is treatment with an anthracycline antibiotic (such as doxorubicin, daunorubicin, epirubicin, or idarubicin), an alkylating agent (such as busulfan, carboplatin, carmustine, chlormethine, cisplatin, cyclophosphamide, or mitomycin), a taxane (such as docetaxel, cabazitaxel, paclitaxel), a topoisomerase inhibitor (such as etoposide, tretinoin, or vinca alkaloids), or anantimetabolite (such as cladribine, cyarabine, or 5-FU). In certain embodiments, the cancer therapy is treatment with an anthracycline antibiotic, e.g., doxorubicin, and the cancer being treated is a leukemia, lymphoma, breast cancer, prostate cancer, ovarian cancer, or lung cancer. In certain embodiments, the cancer therapy is treatment with an anthracycline antibiotic, e.g., doxorubicin, alone or in combination with cyclophosphamide, trastuzumab and/or paclitaxel), and the cancer being treated is a breast cancer, sarcoma, lymphoma, or leukemias. In certain embodiments, the cancer therapy is treatment with an alkylating agent, e.g., cyclophosphamide, and the cancer being treated is a lymphoma, leukemia, or myeloma (e.g., multiple myeloma). In certain embodiments, the cancer therapy is treatment with an inhibitor of microtubule polymerization, e.g., paclitaxel, and the cancer being treated is a breast cancer or a lung cancer. In certain embodiments, the cancer therapy is treatment with a monoclonal antibody, e.g., trastuzumab, and the cancer being treated is a breast cancer or a gastric cancer.

In particular embodiments, the subject is provided with 0.5 mg/kg-5 mg/kg (e.g., 1 mg/kg or 2 mg/kg) of iodide, e.g., NaI, daily.


In particular embodiments, the methods are practiced on a mammalian subject at risk of or suffering cachexia or cardiotoxicity. In some embodiments, the mammalian subject may be selected from human beings, non-human primates, dogs, cats, horses, cattle, sheep, goats, and pigs. Human subjects might be male, female, adults, children, or seniors (65 and older). The mammalian subject can be one diagnosed with cancer, HIV infection, tuberculosis, chronic obstructive pulmonary disease, chronic heart failure, chronic renal failure, a hormone imbalance, severe trauma (e.g., burns), hypermetabolism (e.g., sustained elevated heart rate of at least 6 bpm over normal for a given subject), excessive sympathetic nerve activity, a hyper-inflammatory state (e.g., elevated CRP levels, increased IL-6 levels, increased TNF-alpha levels, and/or increased IFN-gamma levels), a >5 lb weight loss in the preceding two months, and/or an estimated daily caloric intake of <20 cal/kg.


In various embodiments of the methods disclosed herein, the subject being treated has cachexia resulting from a disease or disorder, including but not limited to, cancer (including but not limited to any type of cancer disclosed herein), congestive heart failure, chronic obstructive pulmonary disease, chronic kidney disease, chronic liver disease and AIDS.


In various embodiments of the methods disclosed herein, the subject being treated has cachexia or cardiotoxicity resulting from treatment for a disease or disorder, including but not limited to any of those disclosed herein. In particular embodiments, the disease or disorder is a tumor or a cancer, such as a metastatic cancer; solid tumor cancers; and stage II, III, or IV cancers, and including but not limited to any of those disclosed herein. Thus, in certain embodiments, the subject has cachexia or cardiotoxicity associated with or resulting from a cancer treatment, including but not limited to, treatment with a chemotherapeutic agent and/or treatment with radiation. In particular embodiments, the chemotherapeutic agent includes but is not limited to any of those disclosed herein.


Methods disclosed herein may be used to treat, inhibit, or reduce the severity of any sign or symptom of cachexia. Examples of such signs and symptoms include weakness, fatigue, gastrointestinal distress, sleep/wake disturbances, pain, listlessness, shortness of breath, lethargy, depression, malaise, anorexia, weight loss, muscle atrophy, and loss of lean body mass. In certain embodiments, the sign is anatomical, such as loss of muscle mass, which may be measured by ultrasound of muscle mass or by magnetic resonance imaging (MM). In particular embodiments, the symptom is a reduction in body weight, tumor-free body weight, liver weight, heart weight, muscle weight, or epididymal fat weight. In particular embodiments, the sign is a reduction in tibialis anterior muscle weight. The improvement, if measurable by percent, can be at least 1, 2, 3, 4, 5, 10, 15, 20, 25, 30, 40, 50, 60, 70, 80, or 90%, as compared to the absence of treatment with the iodide, e.g., NaI. Symptoms such as weakness, fatigue, pain, listlessness, depression, and malaise can be measured by techniques known in the art (e.g., using tests such as EORTC-global quality of life, the Beck Depression Inventory, the Zung Self-rating Depression Scale, the Center for Epidemiologic Studies-Depression Scale, the Hamilton Rating Scale for Depression, and patient self-reporting). Functional symptoms may also be determined or measured based on subject's answers to questionnaires directed to functional symptoms, sit to stand testing, six minute walk tests, stair ascent and descent testing, and strength (e.g., hand grip strength or leg extension strength), etc. For assessing anorexia, muscle mass, or lean body mass assessment, dual-emission X-ray absorptiometry scan (DEXA), bioelectrical impedance analysis (BIA), indirect calorimetry, nutrition diaries, and similar known methods can be used.


Methods disclosed herein may be used to treat, inhibit, or reduce the severity of any symptom of cardiotoxicity. Cardiotoxicity symptoms include but are not limited to cardiac dysfunction, which may be determined based on clinical symptoms or the use of echocardiogram or electrocardiogram (EKG). The presence of cardiotoxicity from chemotherapy has been traditionally assessed using clinical symptoms and decreases in left ventricular ejection fraction (LVEF). Examples of cardiotoxicity symptoms include but are not limited to left ventricular dysfunction (LVD): a decrease in cardiac LVEF that is either global or more severe in the septum; or a decline in LVEF of at least 10% to below 55%. In some embodiments, echocardiography is used to measure cardiac function and cardiotoxicity, e.g., subclinical cardiotoxicity. Cardiotoxicity can be measure as asymptomatic failure in the pumping of the heart that can progress to heart failure. It can present as abnormalities on electrocardiograms, irregular heartbeat, pericarditis-myocarditis syndrome (inflammation of the heart muscle or pericardium), or an increase in a brain peptide that is a marker of increased cardiac filling pressures. In some embodiments, nuclear imaging is used to measure cardiotoxicity. Nuclear imaging for cardiotoxicity may check cardiac function prior to and during treatment. A common nuclear medicine heart test is the radionuclide angiogram (RNA). This scan measures the amount of blood ejected from the ventricle with each heart beat (ejection fraction). For example, if the left ventricle ejects 60% of its blood volume with each beat, the LVEF is 0.6 (normal is 0.5 or greater). In some embodiments, an LVEF less than 0.5 is associated with cardiotoxicity. The improvement, if measureable by percent, can be at least 1, 2, 3, 4, 5, 10, 15, 20, 25, 30, 40, 50, 60, 70, 80, or 90%, as compared to the absence of treatment with the iodide, e.g., NaI.


Methods disclosed herein may extend the life of a subject being treated. The extension of survival of a mammalian subject with cachexia can be at least 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, or 200% over the expected lifespan of the subject. The expected lifespan of a subject with a particular disease associated with cachexia can be calculated by known methods, e.g., by averaging historical data. Expected survival times in cancer patients can be determined by known methods, e.g., as described in Llobera et al., Eur. J. Cancer, 36:2036, 2000 and McCusker et al., J. Chron. Dis., 37:377, 1984.

Iodide


The methods disclosed herein may be practiced using any source of iodide, such as NaI. Iodine (I), the second heaviest natural halogen, is the non-metal element with atomic number 53. Under standard pressure and temperature it exists as a solid diatomic 12 molecule. There are 34 iodine isotopes with known half-lives, said isotopes having mass numbers ranging from 108 to 144. Natural iodine, however, consists of one stable isotope, 12I.


In various embodiments, compositions and methods of the present invention comprise iodine. In particular embodiments, it is a reduced form of iodine, such as iodide. Certain embodiments may comprise an iodine-containing compound that is an iodide, or organoiodide.


In certain embodiments, the iodide is selected from or is provided to the subject as: sodium iodide, magnesium iodide, calcium iodide, hydrogen iodide, lithium iodide, silver iodide or zinc iodide. While sodium iodide is recited throughout as an illustrative iodide, it is understood that other sources of iodide disclosed herein may be substituted for sodium iodide in practicing the methods disclosed herein. In particular embodiments, methods disclosed herein are practiced using sodium iodide buffered with sodium chloride. In some embodiments, the iodide formulation or pharmaceutical composition comprises sodium iodide at a concentration of about 7.2 mg/mL balanced with sodium chloride to create a saline solution, with a pH in the range of about 7.0 to about 9.5.

In particular embodiments, the iodide is an organoiodide. Organoiodine compounds are organic compounds that contain one or more carbon-iodine bonds. Almost all organoiodine compounds feature iodide connected to one carbon center. These are usually classified as derivatives of I. Some organoiodine compounds feature iodine in higher oxidation states. Organoiodine compounds, often used as disinfectants or pesticides, include, e.g., iodoform (CHIS), methylene iodide (CH2I2), and methyl iodide (CH3I). In particular embodiment, the organoiodide is a polyiodoorganic compound. Polyiodoorganic compounds are sometimes employed as X-ray contrast agents, in fluoroscopy, a type of medical imaging. A variety of such polyiodoorganic compounds are available commercially; many are derivatives of 1,3,5-triiodobenzene and contain about 50% by weight iodine. In certain embodiments, the agent is soluble in water, non-toxic and/or readily excreted. A representative reagent is Ioversol, which has water-solubilizing diol substituents. Other organoiodine compounds include but are not limited to the two thyroid hormones thyroxine (“T4”) and triiodothyronine (“T3”). Marine natural products are rich sources of organoiodine compounds, including the recently discovered plakohypaphorines from the sponge Plakortis simplex.


The present invention also includes the use of compounds, e.g., drug compounds, into which an iodine is incorporated. For example, an iodine may be incorporated into existing drugs such as N-acetyl cysteine, standard pain relievers, and non-steroidal anti-inflammatory drugs, such as, e.g., aspirin, ibuprofen and naproxen. Most NSAIDs act as nonselective inhibitors of the enzyme cyclooxygenase (COX), inhibiting both the cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) isoenzymes.


In certain embodiments, the iodide is a polyiodide. The polyiodides are a class of polyhalogen anions composed of entirely iodine atoms. The most common and simplest member is the triiodide ion, Other known, larger polyiodides include [I4]2−, [I5], [I7], [I8]2−, [I9], [I10]2−, [I10]4−, [I12]2−, [I13]3−, [I16]2−, [I22]4−, [I26]3−, [I26]4−, [I28]4− and [I29]3−. One example of a polyiodide is Lugol's iodine, also called Lugol's solution. Lugol's solution is commercially available in different potencies of 1%, 2%, or 5% Iodine. The 5% solution consists of 5% (wt/v) iodine (I2) and 10% (wt/v) potassium iodide (KI) mixed in distilled water and has a total iodine content of 130 mg/mL. Potassium iodide renders the elementary iodine soluble in water through the formation of the triiodide (I−3) ion. Other names for Lugol's solution are I2KI (iodine-potassium iodide); Markodine, Strong solution (Systemic); and Aqueous Iodine Solution BCP. Examples of polyiodides, including their ions and counter-cations are shown in Table 1.

EXAMPLES
Example 1
Iodide has Anti-Cachectic Activity

The anti-cachectic activity of iodide was evaluated in a cancer cachexia model of Balb/c mice bearing subcutaneous CT26 tumors. NaI was administered as FDY-5301, which is sodium iodide solubilized in water and balanced with sodium chloride to create an isotonic saline solution, with a pH between 7.0 and 9.5. As shown in the experimental design depicted in FIG. 1, when tumor volume reached 100 mm3, the mice were either left untreated, or treated with one of the following: (i) vehicle control (0.5% CMC); (ii) NaI (FDY-5301) at 2 mg/kg i.v., QD×3 weeks; (iii) bucindolol at 2 mg/kg p.o., QD×3 weeks; or (iv) NaI (FDY-5301) at 40 ug/day slow release via Alzet osmotic pump (flow rate 0.11 uL/h) s.c. for 20 days. On day 14, 1 hour post dosing, blood samples were taken from three animals from groups 2, 3, and 5. On day 20, the animals were humanely euthanized and tumor and animal characteristics were measured. Prior to euthanasia, blood samples were collected for evaluation of biochemical parameters. Following euthanasia, tumor tissue and organs, muscles were collected and weighed.


As shown in FIG. 2, treatment of groups 3, 4, and 5 resulted in significant inhibition of tumor growth. The difference in tumor volume was statistically significant when respective test groups (FDY-5301 and bucindolol) were compared with vehicle control group. All the tumor bearing groups had a significant increase in tumor volume over time, but no significant difference was observed among the treatment groups. Antitumor activity was evaluated as maximum tumor growth inhibition (TGI) in comparison to the vehicle control group. The % tumor grow inhibition (TGI) on day 20 for FDY-5301 (2 mg/kg, iv), bucindolol (2 mg/kg, po), and FDY-5301 (slow release via Alzet osmotic pump) treatment groups were found to be 31%, 24%, and 23%, respectively. The difference in tumor weight was statistically significant when respective test group were compared to vehicle control group.


There was no difference in initial body weight among all groups. As the body weight of the normal group grew during the study period, the body weight of the vehicle control group increased during the initial nine days and then mild to moderate body weight loss was observed from day 10 until the end of treatment. There was significant % body weight loss observed in vehicle control group (−8% loss) when compared with the normal group. However, the treatment groups (FDY-5301 (2 mg/kg, iv), bucindolol (2 mg/kg, po), and FDY-5301 (slow release via Alzet osmotic pump)) showed progressive body weight gain throughout the experimental period. From day 12 to day 20, a significant decrease was observed in body weight of vehicle control animals (considering without tumor weight) compared to normal control animals. However, a significant increase in body weight (without tumor weight) was observed in all treatment groups as compared to vehicle control body weight. Of note, treatment of groups 3, 4 and 5 also resulted in increased body weight at day 20 (FIG. 3 and FIG. 4A). In addition, tumor-free body weight (FIG. 4B) and % tumor-free body weight change (FIG. 4C) both also increased for group 3, 4, and 5 treated animals, with the greatest change seen in group 5 animals (FIGS. 4A-4C). Food consumption during the experiment is shown in FIG. 5. While tumor weight was reduced in animals of treatment groups 3, 4, and 5 (FIG. 6A), body weight minus tumor weight was significantly greater in animals of treatment groups 3, 4, and 5, as compared to animals treated with vehicle control (group 2)(FIG. 6B).


Examination of the weight of various organs demonstrated that animals of treatment groups 3, 4, and 5 had increased liver and heart weight as compared to animals treated with vehicle control (FIGS. 7A and 7B). Vehicle control (cachexia) group had no effect on the weight of the kidney. However, the weight of the liver, heart, lung and epididymal fat were significantly lower than the normal control group. The spleen weight was almost double in all the tumor bearing groups, which could be due to immune and inflammatory responses.


Similar examination of the weight of various muscles demonstrated that animals of treatment groups 3, 4, and 5 had increased tibialis anterior muscle weight as compared to animals treated with vehicle control (FIG. 8B). Vehicle control (cachexia) group showed significant weight loss in gastrocnemius, tibialis anterior and soleus muscles compared to the normal group. However, significant weight gain (moderate) in tibialis anterior muscle was observed in all treatment groups as compared to the vehicle control group. However, other muscles like gastrocnemius and soleus muscle weight was marginally higher in treatment groups as compared to the vehicle control group.


Biochemical analysis of the blood samples showed that while cholesterol, HDL, creatine kinase, glucose, and total protein levels were about the same in all animals, animals of treatment group 5 had lower triglyceride, higher LDL, and lower VLDL as compared to animals treated with vehicle control (FIGS. 9A-9H). Analysis of serum cytokine levels showed no significant difference in TNF-α or IL-6 levels between animals of treatment groups 3, 4, and 5 as compared to those treated with vehicle control (FIGS. 10A and 10B). There was no significant change in serum cholesterol or glucose levels in any of the groups. Serum triglyceride level in the vehicle control group was significantly high compared to the normal control group. However, triglyceride level in treatment with bucindolol and FDY-5301 (slow release via Alzet osmotic pump) was significantly lower and FDY-5301 (2 mg/kg, iv) marginally lower compared to the vehicle control group. Serum HDL level was significantly lower in the vehicle control group when compared to the normal control group. However, the serum HDL levels in all three treatment groups (3, 4, and 5) were marginally higher than the vehicle control group. Serum LDL level was significantly high in all treatment groups compared to normal control. Treatment with FDY-5301 (Slow release via Alzet osmotic pump) showed significant increase in LDL level compared to vehicle control. Whereas, non-significant change in LDL level was observed in other two treatment group (FDY-5301 (2 mg/kg, i.v), Bucindolol (2 mg/kg, p.o)) compared to vehicle control. Serum VLDL level was significantly high in vehicle control group compared to normal control. Whereas, the VLDL level was lower in all the treatment group. Bucindolol (2 mg/kg, p.o) & FDY-5301 (Slow release via Alzet osmotic pump) treatment showed significant decrease in VLDL level. Creatine kinase level in vehicle control group was non-significantly lower than normal control. Treatment with Bucindolol (2 mg/kg, p.o) showed higher level compared to vehicle control whereas, the treatment with FDY-5301 (2 mg/kg, i.v), & FDY-5301 (Slow release) showed marginal decrease levels were observed. The total protein level was significantly lower in vehicle control group compared to normal control, whereas, protein levels in all treatment groups were similar.


Plasma cytokine analysis showed a significant increase in TNF-α in vehicle control compared to normal control animals. The TNF-α level of FDY-5301 (2 mg/kg, iv) treatment group was non-significantly lower, whereas treatment with bucindolol (2 mg/kg, po) or FDY-5301 (slow release via Alzet osmotic pump) showed marginally higher levels of TNF-α when compared with the vehicle control group. IL-6 level was higher in all treatment groups, including vehicle control, when compared with normal control. However, IL-6 level was marginally lower in all treatment groups when compared to vehicle control.


Example 2
Muscle Histology and Morphometry

Morphometric evaluation of transverse sections of muscle fiber area (um2) was performed on tibialis anterior, gastrocnemius, and soleus muscles from the animals described in Example 1, for evaluation of anti-cachectic properties of FDY-5301 and bucindolol in the cancer cachexia model.


In all of the three muscles examined, there was a reduction in muscle fiber area in the vehicle control group as compared to the normal group (FIGS. 11, 17, and 23). In morphometric evaluation of tibialis anterior muscle, FDY-5301 (slow release via Alzet osmotic pump) showed significant increase in the muscle fiber area when compared to the vehicle control group (FIGS. 12-16). However, no significant increase in muscle fiber area was observed in gastrocnemius or soleus muscle when compared to the vehicle control group (FIGS. 18-22 and 24-28).


Example 3
Sodium Iodide Prevents Chemotherapy Induced Cardiotoxicity

This study demonstrates the efficacy of sodium iodide (FDY-5301) delivered by a single i.v. bolus or continuously (using a subcutaneous (s.c.) osmotic pump) in preventing cardiotoxicity induced by doxorubicin chemotherapy.


Male C57Bl/6 mice (˜10 weeks old) were given a 15 mg/kg i.p. bolus of doxorubicin to induce cardiotoxicity. Assessment of ejection fraction was performed via ultrasound at baseline (day 0, prior to any doxorubicin administration) and on days 3, 7, 14 or 28 days post administration. Dosing of placebo or FDY-5301 was done in a blinded fashion, as was all ultrasound analysis.


A single 2 mg/kg i.v. bolus of FDY-5301 was administered by the retro orbital (r.o.) route and immediately followed by 15 mg/kg doxorubicin i.p. Placebo treated animals received saline. A Vevo® 2100 imaging system was used to assess cardiac function on days 0 (baseline), 7, 14, & 28. As shown in FIG. 29, treatment with FDY-5301 was associated with less of a reduction in change in ejection fraction from baseline at days 7, 14, & 28.


A single 2 mg/kg i.v. bolus of NaI was administered by the retro orbital (r.o.) route followed immediately by the s.c. implantation of an osmotic pump designed to deliver 2 mg/kg/day of NaI. The mice then received a 15 mg/kg doxorubicin i.p. bolus. Placebo treated animals received saline (and an osmotic pump filled with saline). Cardiac function was assessed on days 0 (baseline), 3, 7 & 14. As shown in FIG. 30, following a transient increase in EF (in both the placebo and FDY-5301 treated animals) treatment with FDY-5301 resulted in a stabilized EF (by day 14) while animals receiving placebo showed trends of a reduced EF on day 7 and further reductions on day 14.


The combined results of these studies are shown in FIGS. 31A and 31B. Chemotherapy (doxorubicin) administration caused cardiotoxicity, e.g., reduced ejection fraction. This study shows that FDY-5301 delivered at the time of chemotherapy administration prevents a significant reduction in ejection fraction. Since protected ejection fraction is a measure of preserved (cardiac) muscle function, these results demonstrate that FDY-5301 is effective in preventing or reducing cardiotoxicity.
