  • 61/177,244 filed May 11, 2009, entitled “Methods for the Diagnosis of Oncological Disorders Using Epimetabolic Shifters, Multidimensional Intracellular Molecules or Environmental Influencers” (Attorney Docket No.: 117732-00801), U.S. Provisional Application Ser. No. 61/177,245, filed May 11, 2009, entitled “Methods for Treatment of Metabolic Disorders Using Epimetabolic Shifters, Multidimensional Intracellular Molecules or Environmental Influencers” (Attorney Docket No.: 117732-00901), and U.S. Provisional Application Ser. No.
  • Cancer is presently one of the leading causes of death in developed countries and is a serious threat to modern society. Cancer can develop in any tissue of any organ at any age. Worldwide, more than 10 million people are diagnosed with cancer every year and it is estimated that this number will grow to 15 million new cases every year by 2020. It is believed that cancer causes six million deaths every year or 12% of the deaths worldwide.
  • Cancer has been linked to or associated with many factors over the many years of ongoing research including genetic susceptibility, chromosome breakage disorders, viruses, environmental factors and immunologic disorders. Cancer encompasses a large category of medical conditions. Cancer cells can arise in almost any organ and/or tissue of the body. Cancer develops when cells in a part of the body begin to grow or differentiate out of control.
  • bioactive agents including chemical entities, e.g., small molecules, and biologics, e.g., antibodies, with the desire of providing more beneficial therapies for cancer.
  • bioactive agents tested have worked and provided beneficial therapeutic effects in some individuals or cancer types and others have failed or had minimal therapeutic effects in their testing protocols.
  • Other bioactive agents studied to date have mechanisms of action that are not entirely understood.
  • Coenzyme Q10 also referred to herein as CoQ10, Q10, ubiquinone, or ubidecarenone
  • CoQ10 is a popular nutritional supplement and can be found in capsule form in nutritional stores, health food stores, pharmacies, and the like, as a vitamin-like supplement to help protect the immune system through the antioxidant properties of ubiquinol, the reduced form of CoQ10.
  • CoQ10 is art-recognized and further described in International Publication No. WO 2005/069916, the entire disclosure of which is incorporated by reference herein.
  • CoQ10 is found throughout most tissues of the human body and the tissues of other mammals.
  • the tissue distribution and redox state of CoQ10 in humans has been reviewed in a review article by Bhagavan H N, et al., Coenzyme Q10 : Absorption, tissue uptake, metabolism and pharmacokinetic , Free Radical Research 40(5), 445-453 (2006) (hereinafter, Bhagavan, et al.).
  • Ruiz-Jiminez, et al. Determination of the ubiquinol -10 and ubiquinone -10 ( coenzyme Q 10) in human serum by liquid chromatography tandem mass spectrometry to evaluate the oxidative stress , J. Chroma A 1175(2), 242-248 (2007) (hereinafter Ruiz-Jiminez, et al.) reports that when human plasma was evaluated for Q10 and the reduced form of Q10 (Q10H2), the majority (90%) of the molecule was found in the reduced form.
  • CoQ10 is very lipophilic and, for the most part, insoluble in water. Due to its insolubility in water, limited solubility in lipids, and relatively large molecular weight, the efficiency of absorption of orally administered CoQ10 is poor. Bhagavan, et al. reports that “in one study with rats it was reported that only about 2-3% of orally-administered CoQ10 was absorbed.” Bhagavan, et al. further reports that “[d]ata from rat studies indicate that CoQ10 is reduced to ubiquinol either during or following absorption in the intestine.” CoQ10 has been associated with cancer in the literature for many years.
  • Lockwood, et al. Progress on Therapy of Breast Cancer with Vitamin Q 10 and the Regression of Metastases , Biochemical and Biophysical Research Communication 212, 172-177 (1995) (hereinafter “Lockwood, et al.”) is another review article that reports on the “[p]rogress on therapy of breast cancer with Vitamin Q10”.Lockwood, et al. refers to Folkers, et al., which “covers 35 years of international research on animals and humans which revealed variable levels of vitamin Q10 in non-tumor and tumor tissues and includes data on vitamin Q10 which are intrinsic to the host defense system as based on increased survivors of treated mice with tumors”. Lockwood, et al.
  • the NCI cites three small studies on the use of CoQ10 as an adjuvant therapy after standard treatment in breast cancer patients, in which some patients appeared to be helped by the treatment, and reiterates that “weaknesses in study design and reporting, however, made it unclear if benefits were caused by the coenzyme Q10 or by something else.”
  • the NCI specifies that “these studies had the following weaknesses: the studies were not randomized or controlled; the patients used other supplements in addition to coenzyme Q10; the patients received standard treatments before or during the coenzyme Q 10 therapy; and details were not reported for all patients in the studies.”
  • the NCI further reports on “anecdotal reports that coenzyme Q10 has helped some cancer patients live longer, including patients with cancers of the pancreas, lung, colon, rectum and prostate,” but states that ‘the patients described in these reports, however, also received treatments other than coenzyme Q10 including chemotherapy, radiation therapy and surgery.”
  • the formulations of Mazzio 2006 contain one or more compounds that synergistically promote oxidative metabolism and/or impede lactic acid dehydrogenase or anaerobic glucose metabolism and more particularly are described as containing “2,3-dimethoxy-5-methyl-1,4-benzoquinone (herein also termed “DMBQ”) (quinoid base) and options for the entire ubiquinone series including corresponding hydroquinones, ubichromenols, ubichromanols or synthesized/natural derivatives and analogues. See Mazzio 2006 at page 3, paragraph 0010.
  • DMBQ 2,3-dimethoxy-5-methyl-1,4-benzoquinone

  • NM23A Non-metastatic cells 1, protein (NM23A, also known as NME1) is thought to be a metastasis suppressor. This gene (NME1) was identified because of its reduced mRNA transcript levels in highly metastatic cells. The protein has activity as a nucleoside diphosphate kinase (NDK) and exists as a hexamer composed of ‘A’ (encoded by this gene) and ‘B’ (encoded by NME2) isoforms. Mutations in this gene have been identified in aggressive neuroblastomas. NDK activities maintain an equilibrium between the concentrations of different nucleoside triphosphates such as, for example, when GTP produced in the citric acid (Krebs) cycle is converted to ATP. The NDK complex is associated with p53 through interaction with STRAP. It is noteworthy that STRAP is linked to HNF4A. Thus, NM23A is a potential protein involved in pathways important for cell control and disease treatment.

  • Evaluation was based on the measurement of levels of radioactivity of serum, urine, feces and target organs (liver, pancreas and spleen) at the various time points with the objective of determining relative levels of percutaneous penetration of the test article over 24 hours and determining where the drug accumulates with the method of application.
  • Disintegrations per minute are presented in Table 63 and were measured on a scintillation counter for each type of tissue sample from each animal. The average DPM for each sample type was calculated. After the results were converted to 1 mL amounts, the averages were then divided by average organ weights to obtain the DPM per tissue gram result. The control (Group I) results were then subtracted from each of the other group results to remove background radiation amounts and obtain the actual number of average DPM per tissue gram for each sample in the group. By dividing by a constant of 2,220,000, the results were converted to microcuries per tissue gram. The final results represent picocuries (microcuries ⁇ 1000) per tissue gram. The results for the organs were presented in the chart below and in FIG. 41 . Please note that the present application does not contain a Table 94.
  • the data reflects that the test article accumulated substantially in the pancreas at approximately eight (8) hours after dosing and also, in lesser amounts, in the liver at eight hours after dosing.
  • the amount of picocuries per tissue gram in the spleen and pancreas decreased to nearly zero by 18 hours after dosing.
  • the Hour 0 liver results were abnormal because of a single animal with an exceptionally high amount of DPM at zero hours after dosing.
  • One possible explanation for this abnormally high result is that the animal managed to ingest the test article directly, either by licking its own skin or licking its paws after rubbing the dose site. That possibility would send the test article to the liver much quicker than percutaneous absorption.
  • the liver amounts decreased slightly at 12 hours but then increased slightly at 18 hours and remained consistent through 24 hours.
  • Groups II-VIII were dosed with 4.112 microcuries of test article.
  • the chart below presents the amount of microcuries in each target organ at each time period.
  • the average percentage of test article in microcuries that reached the target organs is 0.03%, 0.07% and 0.01% for the pancreas, liver and spleen, respectively.
  • test article accumulated substantially in the feces at eight hours after dosing, continued to be present at 12 hours after dosing but was substantially lower by 18 hours after dosing. There was no indication that the test article accumulated in the urine at any point during the study.
  • test article did not accumulate in the blood; with the exception that test article may have been present in the blood at 18 hours after dosing. It is an oddity that there was no significant amounts of test article found in the blood, especially since test article was observed in the liver and pancreas.
  • One explanation is percutaneous absorption of the test article through the skin directly to the organs; however, it is unlikely that the test article would not enter the blood after penetrating the skin.
  • Another possibility is that the blood immediately recognized a foreign substance and deposited the test material in the liver. The last dosing for Group II was at 10:23 am and the first sacrificed for Group II was at 10:45 am. Twenty-two minutes may have been enough time for the blood to rid itself of the foreign material.
  • Group IX data was calculated separately as the animals in Group IX were dosed repeatedly instead of once and were allowed 7 days to absorb the test article.
  • Group IX data is presented in the charts below.
  • Average picocuries per tissue gram for Groups II-VIII were 1.24, 2.83 and 0.38 for the pancreas, liver and spleen respectively.
  • Group IX results for the organs were lower than average for the pancreas, close to average for the liver and higher than average for the spleen.
  • the data indicates that there were increasing amounts of test article in the spleen by Day 7 and that the amounts of test article in the liver at Day 7 were comparable to the same amounts found in the liver at 18 and 24 hours after dosing.
  • Group IX blood results indicate that the test article was not present in the blood.
  • test article could have been ingested directly by the animals, either by licking the dose itself or licking paws that had rubbed on the dose site.
  • ROS reactive oxygen species
  • a progressive shift of energy generation from oxidative phosphorylation to glycolysis would be essential for a cell to maintain energy production to maintain physiological functions and could be associated with the progression of a normal cell phenotype to that of a cancer cell.
  • the progressive shift in cellular energy (bioenergetic) profile in tandem with accumulated alteration (mutations) in mitochondrial genetic make-up alters the cellular metabolome. Changes in the whole cell metabolomic profile as a consequence of mitochondrial phosphorylation to glycolysis transition corresponds to an abnormal bioenergetic induced metabolomic profile and is the underlying cause supporting carcinogenesis.
  • Targeted intervention using an endogenous molecule to elicit a cellular metabolomic shift towards conditions of a non-cancerous normal mitochondrial oxidative phosphorylation associated cellular bioenergetic state represents a therapeutic endpoint in the treatment of cancer.
