Definitions
- the invention relates to the use of urate oxidase, preferably recombinant urate oxidase, for example Rasburicase, for producing a medicament for the treatment or prophylaxis of disorders or indirect sequelae of the heart caused by ischemic or reperfusion events, for example during and after cardiac surgery like CABG (coronary artery bypass graft), PCI (percutaneous coronary intervention), transplantation, post myocardial infarction and for the treatment or prophylaxis of coronary artery disease or heart failure, for example congestive heart failure.
- CABG coronary artery bypass graft
- PCI percutaneous coronary intervention
- transplantation post myocardial infarction
- post myocardial infarction for the treatment or prophylaxis of coronary artery disease or heart failure, for example congestive heart failure.
- Uric acid is the end product of purine metabolism in birds, reptiles, primates and humans and is produced in the liver by oxidation of xanthine and hypoxanthine. In all other mammals, uric acid is further oxidized by the enzyme urate oxidase to allantoin. However, humans lack this enzyme. As uric acid has relatively poor water solubitlity, the increase in plasma levels of uric acid is known to be causative for several diseases such as gout. An acute elevation of uric acid leads to acute renal failure caused by the precipitation of crystals of uric acid in renal tubules (Ejaz A.A. et al., Clin. J. Am. Nephrol. (2007) 2:16-21).
- Increase of uric acid production is caused in general in patients suffering from purine metabolism disorders such as hereditable hyperuricaemia.
- purine metabolism disorders such as hereditable hyperuricaemia.
- acute elevation of high levels of uric acid is also observed in any patient undergoing massive cell death such as during treatment of cancer with cytostatics. The latter is known to lead to the so-called tumor lysis syndrome where massive cell death leads to liberation of nucleic acids being rapidly catabolized into uric acid as the end product due to purine metabolism.
- massive death of cells is also observed in any pathophysiological situation of ischemia and reperfusion and therefore also during cardiac surgery like CABG (coronary artery bypass graft), PCI (percutaneous coronary intervention), transplantation, post myocardial infarction, coronary artery disease or heart failure.
- CABG coronary artery bypass graft
- PCI percutaneous coronary intervention
- Treatment with Benzbromaron enhances renal excretion of uric acid by targeting renal uric acid reabsorption.
- the net effect under benzbromeron treatment is increased excretion of uric acid.
- Treatment has to begin by subtreshold dosing since Benzbromarone itself can trigger the precipitation of uric acid in the kidney or urether.
- Allopurinol Another approach targets the catabolism of purines into uric acid due to inhibition of xanthinoxidase, a key enzyme in purine metabolism: Allopurinol (4-hydroxypurinol), an analogue of xanthine, is an inhibitor of xanthinoxidase leading to decreased generation of uric acid. Treatment with Allopurinol is currently considered the standard pharmacological treatment for hyperuricemia-associated diseases such as gout. During treatment with Allopurinol, instead of uric acid, the precursors xanthines accumulate and are mainly excreted via the kidney.
- Allopurinol Treatment with Allopurinol is preventive to avoid high uric acid levels but it is unsuitable in cases of already elevated uric acid levels and is moreover known to induce gout on its own. In case of prevention the tumor lysis syndrome during treatment of cancer, Allopurinol is given before cytotoxic treatment. Beside the application of allopurinol, management is directed to normalize metabolic abnormalities and preventing further renal damage. iii) Urate oxidase
- Urate oxidase (Uric acid oxidase, urate oxygen oxidoreductase, EC 1.7.3.3) catalyses the oxidation of uric acid to allantoin, a water-soluble product that is easily excreted by the kidney (scheme 1).
- the protein enzyme urate oxidase can, for example, be obtained from Aspergillus flavus.
- the cDNA coding for this protein has been cloned and expressed in Escherichia coli (Legoux R. et al., J. Biol. Chem., 1992, 267, (12), 8565-8570), in Aspergillus flavus (Chevalet L. et al., Curr. Genet., 1992, 21 , 447-453) and in Saccharomyces cerevisiae (Leplatois P. et al., Gene., 1992, 122, 139-145).
- Recombinant urate oxidase is urate oxidase produced by genetically modified microorganisms and can, for example, be obtained from the above mentioned genetically modified strains of Escherichia coli and Saccharomyces cerevisiae.
- Rasburicase is a recombinant urate oxidase enzyme produced from genetically modified strain of Saccharomyces cerevisiae cloned with cDNA from a strain of Aspergillus flavus (Oldfield V et al., Drugs (2006) 66 (4):529-545, Leplatois P. et al., Gene., 1992, 122, 139-145).
- Rasburicase is a tetrameric protein with identical subunits of a molecular mass of about 34 kDa each ( Figure 1) - similar to the native Aspergillus flavus urate oxidase (Bayol A. et al., Biotechnol. Appl. Biochem. 2002, 36, 21 -31).
- Rasburicase Due to its mode of action, instead of treatment with allopurinol, use of Rasburicase is now the preferred treatment in situations of acute and massively increased plasma uric acid levels in the context of prevention of tumor lysis syndrome.
- ROS reactive oxygen species
- the invention relates to the use of an urate oxidase, preferably recombinant urate oxidase, for example Rasburicase, for producing a medicament for the treatment or prophylaxis of disorders or indirect sequelae of the heart caused by ischemic or reperfusion events, for example during and after cardiac surgery like CABG (coronary artery bypass graft), PCI (percutaneous coronary intervention), transplantation, post myocardial infarction and for the treatment or prophylaxis of coronary artery disease or heart failure, for example congestive heart failure.
- CABG coronary artery bypass graft
- PCI percutaneous coronary intervention
- transplantation post myocardial infarction
- post myocardial infarction for the treatment or prophylaxis of coronary artery disease or heart failure, for example congestive heart failure.
- additional treatment with a scavenger for H 2 O 2 is preferred, for example vitamins A, C or E, Trolox, Oligomere Proanthocyanidine, Gluthation, L-N- Acetylcystein, Ebselen, Lycopin, Flavonoid, Catechin und Anthocyan, more preferably L-ascorbic acid.
- a scavenger for H 2 O 2 for example vitamins A, C or E, Trolox, Oligomere Proanthocyanidine, Gluthation, L-N- Acetylcystein, Ebselen, Lycopin, Flavonoid, Catechin und Anthocyan, more preferably L-ascorbic acid.
- compositions comprise, as an active constituent, an effective dose of Rasburicase in addition to customary, pharmaceutically unobjectionable carriers and assistants and optionally also one or more other active pharmacological ingredients, for example ascorbic acid.
- the pharmaceutical formulations contain normally from 0.1 to 90% by weight of Rasburicase.
- the pharmaceutical formulations can be produced in a manner known per se. To this end, the active ingredients and/or their physiologically compatible salts, together with one or more solid or liquid pharmaceutical carriers and/or assistants, are converted to a suitable administration form or dosage form, which can then be used as a medicament in human medicine.
- Medicaments which comprise Rasburicase can be administered, for example, parenterally, intravenously, rectally, nasally, by inhalation or topically, the preferred administration depending on the particular case.
- excipients which are suitable for the desired pharmaceutical formulation are familiar to those skilled in the art on the basis of their expert knowledge.
- solvents for example, antioxidants, dispersants, emulsifiers, antifoams, flavorings, preservatives, solubilizers, agents for achieving a depot effect, buffer substances or colorings.
- the active compounds used are converted to solution, suspension or emulsion.
- useful solvents are: water, physiological saline or alcohols, for example ethanol, propanol, glycerol, and additionally also sugar solutions such as glucose or mannitol solutions, or else a mixture of the different solvents mentioned.
- suitable pharmaceutical formulations for administration in the form of aerosols or sprays are solutions, suspensions, emulsions or vesicular and micellar medicament forms of the active ingredients or their physiologically compatible salts in water or in a pharmaceutically unobjectionable water-miscible or oily solvent, or a mixture of such solvents.
- suitable for administration in the form of aerosols or sprays, for example for nasal administration are powders of the active ingredients or their physiologically compatible salts.
- all formulations may also comprise other pharmaceutical excipients such as isotonizing additives, surfactants, emulsifiers and stabilizers, and also a propellant gas.
- the formulations mentioned may additionally be in the form of freeze-dried products.
- the dosage of Rasburicase to be administered in accordance with the invention depends upon the individual case and, for optimal action, should be adjusted to the circumstances of the individual case as usual. For instance, it depends of course upon the frequency of administration and upon the potency and duration of action of the compounds used in each case for treatment or prophylaxis, but also upon the nature and severity of the disease to be treated, and also on the gender, age, weight and individual responsiveness of the human or animal to be treated, and upon whether acute or chronic treatment or prophylaxis is being practiced.
- the dosage of Rasburicase may typically vary within the range from 1 mg to 1 g per day and per person (at body weight about 75 kg), preferably from 5 to 750 mg per day and person, for example from 100 to 150 mg per day and person. However, higher doses may also be appropriate.
- the daily dose of the active ingredients may be administered all at once or it may be divided between a plurality of, for example 2, 3 or 4, administrations.
- Example A Aqueous solution for intravenous administration To prepare 10 ml of solution comprising 50 ⁇ g of active compound per ml, 0,5 mg Rasburicase were dissolved in 10 ml of isotonic (0.9%) sodium chloride solution.
- the isolated hearts of male Wistar rats were used which were purchased from our Laboratory Animal Science and Welfare (LASW).
- the heart function was investigated on the "Isolated Working Heart” model as previously described (Itter G et al., Laboratory Animals (2005) 39; 178-193).
- the hearts were first perfused according to Langendorff's method with an oxygenated (95% O 2 , 5% CO 2 ) noncirculating Krebs-Henseleit solution of the following compositions (mmol/L): NaCI, 118; KCI, 4.7; CaCI 2 , 2.5; MgSO 4 , 1.6; NaHCO 3 , 24.9; KH 2 PO 4 , 1.2; glucose, 5.5; Na-pyruvate, 2.0.
- a catheter placed into the pulmonary artery drained the coronary effluent perfusate that was collected for determination of coronary flow and venous PQ 2 measurements.
- the left atrium was cannulated by an incision of the left auricle. After a 15-minute equilibration period at a fixed perfusion pressure of 60 mmHg, the heart was switched into the working mode at a fixed filling pressure of 11 mmHg.
- Coronary flow (CF) and pressure signals (dP/dt max ) were sampled at 500 Hz, averaged every 2 seconds.
- Table 1 shows that concentrations higher than 100 ⁇ M H 2 O 2 strongly reduced coronary flow and contractility.
