COMBINATIONAL THERAPEUTIC METHODS EMPLOYING NITRIC OXIDE SCAVENGERS

Abstract: In accordance with the present invention, there are provided combinational therapeutic methods for the in vivo inactivation or inhibition of formation (either directly or indirectly) of species which induce the expression of nitric oxide synthase, as well as reducing nitric oxide levels produced as a result of .No synthase expression. In contrast to the inhibitory approach described in the prior art (i.e., wherein the function of the enzymes responsible for nitric oxide production is inhibited), the present invention employs a combination of inactivation (or inhibition) and scavenging approach whereby the stimulus of nitric oxide synthase expression is inactivated, or the production thereof is inhibited, and overproduced nitric oxide is bound in vivo to a suitable nitric oxide scavenger. The resulting complexes render the stimulus of nitric oxide synthase expression inactive (or inhibit the production thereof), and nitric oxide harmless. The resulting complexes are eventually excreted in the urine of the host. Further in accordance with the present invention, there are provided compositions and formulations useful for carrying out the above-described methods.

Description: COMBINATIONAL THERAPEUTIC METHODS EMPLOYING NITRIC OXIDE SCAVENGERS FIELD OF THE INVENTION The present invention relates to methods for directly or indirectly treating the production of species which induce the expression of nitric oxide synthase in mammals. In a particular aspect, the present invention relates to methods for inactivating such species, or inhibiting the production of such species, while, at the same time, reducing nitric oxide levels, by co-administration of agents which inactivate (or inhibit the production of) such species, along with a scavenger of overproduced nitric oxide. In a further aspect, the present invention relates to compositions and formulations useful in the methods disclosed herein. BACKGROUND OF THE INVENTION In 1987, nitric oxide («NO), a gaseous free- radical, was discovered in humans (see, for example, Ignarro et al., in Proc . Natl . Acad . Sci . , USA 84:9265-69 (1987) and Palmer et al., in Nature 327:524-26 (1987)) . As an indication of the significance of this discovery for the understanding of human physiology and pathophysiology, Science magazine selected nitric oxide as the molecule of the year in 1992. Nitric oxide is formed from the terminal guanidino nitrogen atom of L-arginine by nitric oxide synthase (NOS; see, for example, Rodeberg et al., in Am . J. Surg . 170:292-303 (1995), and Bredt and Snyder in Ann . Rev . Biochem . 63:175-95 (1994)). Two major forms of nitric oxide synthase, constitutive and inducible enzymes, have been identified. Under physiological conditions, a low output of •NO is produced by the constitutive, calcium-dependent NOS isoform (cNOS) present in numerous cells, including endothelium and neurons. This low level of nitric oxide is involved in a variety of regulatory processes, e.g., blood vessel homeostasis, neuronal communication and immune system function. On the other hand, under pathophysiological conditions, a high output of «NO is produced by the inducible, calcium-independent NOS isoform (iNOS) which is expressed in numerous cell types, including endothelial cells, smooth muscle cells and macrophages. These high levels of nitric oxide have been shown to be the etiology of endotoxin shock. This high output of « NO further contributes to inflammation-related tissue damage, neuronal pathology, N-nitrosamine-induced carcinogenesis and mutations in human cells and bacteria via deamination reaction with DNA. Nitric oxide can therefore be seen to be a mixed blessing, being very desirable when present in small amounts, while potentially being highly detrimental when produced in excessive quantities. Nitric oxide is a potent vasodilator (see, for example, Palmer in Arch . Surg . 128:396-401 (1993) and Radoms i & Moncada in Thromb . Haemos . 70:36-41 (1993) . For example, in blood, «NO produced by the endothelium diffuses isotropically in all directions into adjacent tissues. As •NO diffuses into the vascular smooth muscle, it binds to guanylate cyclase enzyme, which catalyzes the production of cGMP, inducing vasodilation (see, for example, Ignarro, L.J., Ann. i?ev. Toxicol . 30:535-560 (1990); Moncada, S. , Acta Physiol . Scand . 145:201-227 (1992) ; and Lowenstein and Snyder, Cell 70:705-707 (1992)). The overproduction of nitric oxide causes an extreme drop in blood pressure, resulting in insufficient tissue perfusion and organ failure, syndromes that are associated with many diseases and/or conditions (e.g., septic shock, overexpression of cytokines, allograft rejection, and the like) . The overproduction of nitric oxide is triggered by a number of stimuli, such as, the overproduction of inflammatory cytokines (e.g., tumor necrosis factor (TNF) , interleukin-1 (IL-1) , interferons, endotoxin, and the like) . Additionally, the overproduction of «NO has been discovered to be one of the major side-effects of cytokine therapy (see, for example, Miles et al. , in Eur. J. Clin . Invest . 24:287-290 (1994) and Hibbs et al., in J. Clin . Invest . 89:867-877 (1992)) . Thus, abnormally elevated nitric oxide levels have been linked to many inflammatory and infectious diseases. Inflammatory cytokines (e.g., TNF, interleukins or interferons) and infectious agents (e.g. , endotoxin) induce nitric oxide overproduction by inducing transcription of the inducible nitric oxide synthase gene, leading to the production of inducible nitric oxide synthase, which in turn results in the overproduction of nitric oxide. The production of nitric oxide by the above- described pathway can be disrupted in a variety of ways. Thus, for example, there have been attempts to develop monoclonal antibodies (e.g., anti-endotoxin antibodies, anti-cytokine antibodies, anti-cytokine receptor antibodies, and the like) in efforts to block the » N0 production pathway at the transcriptional level. Unfortunately, however, such efforts have met with very limited success (see, for example, Glauser et al., in Clin . Infect . Dis . 18:S205-16 (1994) and St. John & Dorinsky, in Chest 103:932-943 (1993)) . At least one reason for the relative lack of success in the art is the fact that the production of inflammatory cytokines is short-lived (see, for example, ange & Steinsham in Eur . J . Haematol . 50:243-249 (1993)), while overproduction of nitric oxide lasts several days, causing systemic hypotension, insufficient tissue perfusion and organ failure. Thus, for example, during endotoxemia, TNF production peaks at about 1-2 hours. Therefore, in order to be effective, anti-TNF antibodies would have to be administered at an early stage after infection. Indeed, in many clinical settings, patients are likely to already have been infected with bacteria prior to being admitted. Accordingly, such therapeutic methods have met with only limited success. Currently, many pharmaceutical companies have turned their attention to the design and development of substrate or product analogue inhibitors of the enzyme, NOS, in efforts to treat the overproduction of -NO. However, recent data show that the inhibition of NOS is detrimental to subjects. For example, rodent studies show that inhibition of the production of nitric oxide causes intrauterine growth retardation and hind-limb disruptions in rats (see, for example, Diket et al. , in Am. J " . Obstet . Gynecol . 171:1243-1250 (1994)). Furthermore, the inhibition of nitric oxide synthesis during endotoxemia has also been shown to be detrimental (see, for example, Minnard et al., in Arch . Surg. 129:142-148 (1994); Luss et al., in Biochem . Biophys . Res . Commun . 204:635-640 (1994) ; and Hargrecht et al., in J . Leuk . Biol . 52:390-394 (1992)) . Similar results have been reported in larger animal studies, such as dogs and swine (see, for example, Statman et al., in J . Surg . Res . 57:93-98 (1994); Mitaka et al. , Am. J . Physiol . 268:H2017-H2023 (1994) ; Robertson, et al., Arch. Surg . 129:149-156 (1994) ; and Henderson et al., Arch . Surg. 129:1271-1275 (1994)). Since a variety of stimuli induce expression of nitric oxide synthase, which, in turn, leads to nitric oxide overproduction (with its attendant detrimental effects) , there is a need in the art to effectively treat both the initial stimulus of nitric oxide synthase expression, and the resulting overproduction of nitric oxide. BRIEF DESCRIPTION OF THE INVENTION In accordance with the present invention, combinational therapeutic methods have been developed for the in vivo inactivation or inhibition of formation (either directly or indirectly) of species which induce the expression of inducible nitric oxide synthase, as well as reducing nitric oxide levels produced as a result of « NO synthase expression. In contrast to the inhibitory approach described in the prior art to address the problem of nitric oxide overproduction (see, for example, Aisaka et al., Biochem. Biophys . Res . Commun . 60:881-886 (1989) ; Rees, et al. , Proc . Natl . Acad . Sci . USA 86:3375-3379, (1989)) ; Henderson et al., in Arch . Surg . 129:1271-1275 (1994); Ha brecht et al., in J. Leuk . Biol . 52:390-394 (1992) ; Luss et al. , in Biochem . and Biophys . Res . Comm . 204:635-640 (1994) ; Robertson et al., in Arch. Surg . 129:149-156 (1994) ; Statman et al., in J . Surg . Res . 57:93-98 (1994); and Minnard et al., in Arch. Surg . 129:142-148 (1994)), the present invention employs a combination of inactivation (and/or inhibition) and scavenging approach whereby the stimulus of nitric oxide synthase expression is inactivated and/or expression thereof is inhibited, and overproduced nitric oxide is bound in vivo to a suitable nitric oxide scavenger. The resulting complexes render the stimulus of nitric oxide synthase expression inactive (or inhibit the production thereof) , while also rendering the resulting nitric oxide harmless. The resulting complexes are eventually excreted in the urine of the host. Further in accordance with the present invention, there have been developed compositions and formulations useful for carrying out the above- described methods. Numerous stimuli for -NO synthase are known in the art. Co-administration of agents which inactivate the stimulus of «NO synthase expression (or inhibit the production thereof) , in combination with nitric oxide scavengers as described herein, provides a more effective means to treat a variety of indications than has previously been described in the art. An exemplary nitric oxide scavenger contemplated for use in the practice of the present invention is a dithiocarbamate-ferrous iron complex. This complex binds to »NO, forming a stable, water-soluble dithiocarbamate- iron-NO complex having a characteristic three-line spectrum (indicative of a mononitrosyl-Fe complex) which can readily be detected at ambient temperatures by electron paramagnetic resonance (EPR) spectroscopy (See Komarov et al., in Biochem . Biophys . Res . Commun . 195:1191-1198 (1993); and Lai and Komarov, FEBS Lett . ,345:120-124, (1994)). This method of detecting «NO in body fluids in real time has recently been described by Lai in U.S. Patent No. 5,358,703, incorporated by reference herein in its entirety. The present invention relates to combinational therapeutic methods for treating the production of species which induce the expression of nitric oxide synthase in mammals. Thus, a dual attack is mounted against a variety of stimuli which lead to the production of dangerously high in vivo levels of -NO. Combinations of agents contemplated for use in the practice of the present invention (i.e., agents capable of inactivating species which induce expression of inducible nitric oxide, or agents which inhibit the production of such species, and nitric oxide scavengers) are administered to a host in need of such treatment. The agent capable of inactivating (or inhibiting the production of) species which induce expression of inducible nitric oxide and «N0 scavengers interact with the stimulus of nitric oxide synthase expression and in vivo produced -NO, respectively, forming a complex between said species and said agent, as well as a stable scavenger-NO complex. Whereas free -NO is a potent vasodilator, chelated «NO complexes are not. The NO-containing complex is then filtered through the kidneys, concentrated in the urine, and eventually excreted by the subject, thereby reducing in vivo «NO levels.

Since individual subjects may present a wide variation in severity of symptoms and each drug has its unique therapeutic characteristics, the precise mode of administration, dosage employed and treatment protocol for each subject is left to the discretion of the practitioner. In accordance with still another embodiment of the present invention, there are provided physiologically active composition(s) comprising a "therapeutic agent" (as described herein) and a nitric oxide scavenging compound (e.g., a compound having the structure I, as described above) , in a suitable vehicle rendering said composition amenable to oral delivery, transdermal delivery, intravenous delivery, intramuscular delivery, topical delivery, nasal delivery, and the like. Depending on the mode of delivery employed, the above-described compositions can be delivered in a variety of pharmaceutically acceptable forms. For example, the above-described compositions can be delivered in the form of a solid, solution, emulsion, dispersion, micelle, liposome, and the like. Pharmaceutical compositions of the present invention can be used in the form of a solid, a solution, an emulsion, a dispersion, a micelle, a liposome, and the like, wherein the resulting composition contains one or more each of the nitric oxide scavenging and therapeutically active compounds contemplated for use in the practice of the present invention, as active ingredients thereof, in admixture with an organic or inorganic carrier or excipient suitable for enteral or parenteral applications. The active ingredients may be compounded, for example, with the usual non-toxic, pharmaceutically acceptable carriers for tablets, pellets, capsules, suppositories, solutions, emulsions, suspensions, and any other form suitable for use. The carriers which can be used include glucose, lactose, gum acacia, gelatin, mannitol, starch paste, magnesium trisilicate, talc, corn starch, keratin, colloidal silica, potato starch, urea, medium chain length triglycerides, dextrans, and other carriers suitable for use in manufacturing preparations, in solid, semisolid, or liquid form. In addition auxiliary, stabilizing, thickening and coloring agents and perfumes may be used. The active compounds (i.e., "therapeutic agents" and nitric oxide scavenging compounds (e.g., compounds of structure I as described herein) ) are included in the pharmaceutical composition in an amount sufficient to produce the desired effect upon the target process, condition or disease. Pharmaceutical compositions containing the active ingredients contemplated herein may be in a form suitable for oral use, for example, as tablets, troches, lozenges, aqueous or oily suspensions, dispersible powders or granules, emulsions, hard or soft capsules, or syrups or elixirs. Compositions intended for oral use may be prepared according to any method known in the art for the manufacture of pharmaceutical compositions. In addition, such compositions may contain one or more agents selected from a sweetening agent (such as sucrose, lactose, or saccharin) , flavoring agents (such as peppermint, oil of wintergreen or cherry) , coloring agents and preserving agents, and the like, in order to provide pharmaceutically elegant and palatable preparations. Tablets containing the active ingredients in admixture with non-toxic pharmaceutically acceptable excipients may also be manufactured by known methods. The excipients used may be, for example, (1) inert diluents such as calcium carbonate, lactose, calcium phosphate, sodium phosphate, and the like; (2) granulating and disintegrating agents such as corn starch, potato starch, alginic acid, and the like; (3) binding agents such as gum tragacanth, corn starch, gelatin, acacia, and the like; and (4) lubricating agents such as magnesium stearate, stearic acid, talc, and the like. The tablets may be uncoated or they may be coated by known techniques to delay disintegration and absorption in the gastrointestinal tract, thereby providing sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate may be employed. They may also be coated by the techniques described in the U.S. Pat. Nos. 4,256,108; 4,160,452; and 4,265,874, to form osmotic therapeutic tablets for controlled release. In some cases, formulations for oral use may be in the form of hard gelatin capsules wherein the active ingredients are mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate, kaolin, or the like. They may also be in the form of soft gelatin capsules wherein the active ingredients are mixed with water or an oil medium, for example, peanut oil, liquid paraffin, or olive oil. The pharmaceutical compositions may be in the form of a sterile injectable suspension. This suspension may be formulated according to known methods using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides, fatty acids (including oleic acid) , naturally occurring vegetable oils like sesame oil, coconut oil, peanut oil, cottonseed oil, etc. , or synthetic fatty vehicles like ethyl oleate or the like. Buffers, preservatives, antioxidants, and the like can be incorporated as required. Compositions contemplated for use in the practice of the present invention may also be administered in the form of suppositories for rectal administration of the active ingredients. These compositions may be prepared by mixing the active ingredients with a suitable non- irritating excipient, such as cocoa butter, synthetic glyceride esters of polyethylene glycols (which are solid at ordinary temperatures, but liquify and/or dissolve in the rectal cavity to release the active ingredients) , and the like. Since individual subjects may present a wide variation in severity of symptoms and each active ingredient has its unique therapeutic characteristics, it is up to the practitioner to determine a subject's response to treatment and vary the dosages accordingly. Typical daily doses of nitric oxide scavengers, in general, lie within the range of from about 10 μg up to about 100 mg per kg body weight, and, preferably within the range of from 50 μg to 10 mg per kg body weight and can be administered up to four times daily. The daily IV dose lies within the range of from about 1 μg to about 100 mg per kg body weight, and, preferably, within the range of from 10 μg to 10 mg per kg body weight. In general, the dosage of nitric oxide scavenger employed in the practice of the present invention falls in the range of about 0.01 mmoles/kg body weight of the subject/hour up to about 0.5 m oles/kg/hr. The invention will now be described in greater detail by reference to the following non-limiting examples. Example 1 Wistar rats (male, 230-300 g) were supplied by Simonson Laboratories (Gilroy, CA) . Lipopolysaccharide (LPS; S. typhosa, endotoxin) was obtained from Sigma (St. Louis, MO) . N-Methyl-D-glucamine and carbon disulfide were obtained from Aldrich (Milwaukee, WI) . N-Methyl-D- glucamine dithiocarba ate (MGD) was synthesized by following the method of Shinobu et al. (Acta Pharmacol . Toxicol . 54:189-194 (1984)) . Example 2 As described previously (see Lai and Komarov in FEBS Lett . 345:120-124 (1994)), one [(MGD) 2 /Fe] complex binds to one molecule of nitric oxide to form a [(MGD) 2 /Fe- NO] complex. Whereas free nitric oxide is a potent vasodilator, nitric oxide bound to [(MGD) 2 /Fe] is not. The resulting complex is then excreted from the body in the urine, thereby reducing in vivo nitric oxide levels. The effects of [(MGD) 2 /Fe] treatment on the mean arterial pressure of endotoxemia in rats are shown in Figure 1. When rats were treated with lethal doses of LPS, the mean arterial pressure dropped gradually with time and reached 75 mm Hg at the end of 2 hours. In controls, when the animals were infused with saline, their mean arterial pressure remained very low; indeed, 11 out of 16 animals died before the end of the experiments. On the other hand, when the LPS-treated animals were infused with [(MGD) 2 /Fe], their mean arterial pressure gradually restored to normal levels, and only 3 out of 16 animals died before the end of the experiments. Therefore, infusions of [(MGD) 2 /Fe] can not only restore blood pressure, but also reduces the mortality rate in endotoxin induced septic shock rats. In summary, [(MGD) 2 /Fe] is potentially useful for the treatment of systemic hypotension (extreme drop in blood pressure) , caused by abnormally elevated levels of nitric oxide; a condition which has been associated with many inflammatory and infectious diseases. In addition, [(MGD) 2 /Fe] has been shown to be safe inasmuch as the animals survived after injections of up to 1% of their body weight without apparent side effects (Lai and Komarov, supra) . Example 3 As previously described (see Komarov and Lai in Biochim . Biophys . Acta 1272:29-36 (1995)), subcutaneous administration of the [(MGD) 2 /Fe] complex reduced in vivo •NO levels in LPS-treated mice. Since excessive «N0 production is known to induce systemic hypotension, injections of the [(MGD) 2 /Fe] complex that reduce in vivo •NO levels should also restore blood pressure in hypotensive animals induced by LPS treatment. To test this idea, experiments were carried out to determine the effects of administration of the [(MGD) 2 /Fe] complex on the blood pressure of the hypotensive rats induced by LPS challenge. Thus, male Wistar rats (230-300 g) fasted overnight were anesthetized with thiobutabarbital (Inactin, 100 mg/kg, i.p.) . A catheter was implanted in the femoral vein for drug infusions. The femoral artery was cannulated for continuous blood pressure measurement. Rats were injected with an i.v. bolus dose of LPS (S.Typhosa endotoxin, 4 mg/kg) . Two hours after LPS challenge, rats were then subjected to one of the following treatments: (a) Control, saline infusion- 1.0 ml saline i.v. injection followed by 1.0 ml/hr of saline infusion for 2.0 hours, (b) [(MGD) 2 /Fe] (at a ratio of 2-to-0.4) -0.1 mmole/kg i.v. bolus injection followed by 0.1 mmole/kg infusion for 2.0 hours, (c) [(MGD) 2 /Fe] (at a ratio of 2-to-0.2) -0.1 mmole/kg i.v. bolus injection followed by 0.1 mmole/kg infusion for 2.0 hours, and (d) [(MGD) 2 /Fe] (at a ratio of 2-to-0)-0.1 mmole/kg i.v. bolus injection followed by 0.1 mmole/kg infusion for 2.0 hours. The results of mean arterial pressure (MAP) measurement as a result of each of these treatments are summarized in Table 1. Table 1 Effects of various ratios of [(MGD) 2 /Fe] treatment on the mean arterial pressure (MAP in mmHg) in lipopolysaccharide (LPS) -induced shock rats Experimental conditions were as described in the text. The values of MAP prior to LPS treatment, n, the number of animals in each group. [(MGD) 2 /Fe] (2/0.4) is defined as the ratio of [(MGD) 2 /Fe] to be 2-to-0.4. The MAP of anesthetized rats was in the range of 96 to 99 mmHg. Two hours after LPS treatment, the MAP decreased to between 71 and 77 mmHg, which is indicative of the onset of systemic hypotension, caused by abnormally elevated levels of nitric oxide, as also shown in Figure 1. While the 2.0 hr saline infusion did not change the MAP, infusions of [(MGD) 2 /Fe] complex at various ratios, ranging from 2-to-0.4 (MGD to Fe) to 2-to-0 (MGD to Fe) , restored the blood pressure to 89-95 mmHg (Table 1) . These results suggest that the i.v. infusion of MGD either with or without added iron (Fe) , can restore blood pressure in hypotensive rats induced by LPS challenge (Table 1) . Since MGD does not bind -NO, it is speculated that the restoration of the MAP by MGD infusion may be attributed to the MGD chelation of cellular iron released by excess «NO production, which is known to attack cellular iron-containing proteins and result in cellular iron loss during sepsis or septic shock (see, for example, Kim et al., in J " . Biol . Chem . 270:5710-5713 (1995)). This example shows that dithiocarbamate- containing nitric oxide scavengers, such as MGD, either with or without added iron, are effective for the treatment of systemic hypotension, a condition which is associated with many inflammatory and/or infectious diseases. Example 4 In order to test the efficacy of the combinational therapy of [(MGD) 2 /Fe] and anti-TNF antibody for treatment of LPS-induced shock, Wistar rats are anesthetized with Ketamine/Xylazine (55 mg/kg plus 5.5 mg/kg) . A catheter is implanted in the femoral vein for drug administration. The femoral artery is cannulated for continuous blood pressure measurement. The animals are allowed to recover from surgery for a period of 3 days prior to experimentation. On the day of the experiment, the conscious rats are retained in restrainers and the artery line is connected to the pressure transducer for recording. Rats are injected with an i.v. bolus dose of LPS (S. Typhosa, endotoxin, 10-20 mg/kg) . Two hours after LPS challenge, rats are then subjected to one of the following treatments (8 animals in each group) : (1) Control, saline infusion - 1.0 ml saline/hr of saline infusion for 6 hours. (2) [(MGD) 2 /Fe] (at a ratio of 5 to 1) - 0.1 mmole/kg/hr infusion for 3 hours, followed by saline infusion for 3 hours. (3) Anti-TNF- 7.5 mg/kg/hr infusion for 3 hours, followed by saline infusion for 3 hours. (4) Co-infusion of [(MGD) 2 /Fe] (0.1 mmole/kg/hr) and Anti-TNF (7.5 mg/kg/hr) for 3 hours, followed by saline infusion for 3 hours. (5) [(MGD) 2 /Fe] (at a ratio of 5-to-l) -0.1 mmole/kg/hr infusion for 3 hours and followed by anti-TNF (7.5 mg/kg/hr) infusion for 3 hours. At the end of the infusion, rats are returned to their cages for observation. The 24-hr survival rates resulting from these various treatments are compared. Since a lethal dose of LPS is used, it is expected that all animals in control group 1 will die within 24 hours. Based on the results presented in Figure 1 (Example 2) , it is expected that about two thirds of the rats in the treatment group (i.e., group 2, treated with [(MGD) 2 /Fe]) will survive after 24 hours. As discussed above, in endotoxemia, TNF production is short-lived and peaks at 1-2 hours. Therefore, the infusion of anti-TNF antibodies at two hours after LPS challenge as indicated in group 3 may not be able to block the induction of the inducible nitric oxide synthase gene, which results in the production of iNOS, resulting in the overproduction of nitric oxide. In group 4, the co-infusion of anti-TNF antibodies and [(MGD) 2 /Fe] is expected to produce a similar survival rate as that for group 2, employing [(MGD) 2 /Fe] infusion alone. On the other hand, it is expected that the infusion of [(MGD) 2 /Fe] for 3 hours, followed by the infusion of anti-TNF antibodies (as done with group 5) will improve the survival rate over that in group 2, because the infusion of anti-TNF antibodies at later hours would inhibit further activation of the inducible NO synthase gene, thereby reducing the further enhancement of excessive NO production. The efficacies of combinational therapy between [(MGD) 2 /Fe] and other therapeutic agents (such as anti- endotoxin antibodies, other anti-cytokine antibodies, anti- cytokine receptor antibodies, and other agents, such as antibradykinin peptides, nitric oxide synthase inhibitors, and the like) can be demonstrated in a similar fashion to that described herein. Example 5 NO production has been shown to be increased during acute cardiac allograft rejection in rats, as evidenced by elevated urinary and plasma nitrate/nitrite levels, preceding and at the time of rejection (see, for example, Winlaw et al., in Transplantation 5_8: 1031 (1994)). Abnormally elevated NO levels appeared to be produced by activated infiltrating host macrophages and cardiac myocytes of the rejecting allograft (see, for example, Yang et al., in J. Clin. Invest. 9_4:714-721 (1994)) . Cyclosporin is widely used as an immunosuppressive agent to prevent allograft rejection, mainly through the inhibition of T cell activation. However, the use of cyclosporin has been associated with multiple side effects, such as, for example, nephrotoxicity, hepatotoxicity and hypertension (see, for example, Atkinson et al., in Transplantation 3j3:34 (1984). Experiments were performed to evaluate the effectiveness of invention combination therapy in preventing cardiac allograft rejection in rats, employing low doses of cyclosporin and MGD/Fe. Organ donors were male Wistar-Furth (WF) strain rats weighing -160-300 grams. Organ recipients were male Lewis (Lew) strain rats weighing -210-340 grams. Lewis rats underwent either syngeneic (i.e., Lew-Lew) or allogeneic (i.e., WF-Lew) heterotropic cardiac transplantation to the abdominal aorta and vena cava by standard microvascular surgical techniques using sodium pentobarbital anesthesia (50 mg/kg) . All cardiac transplants were observed to have good contractile function, and there were no early deaths from surgical complications. Graft function was monitored by palpation through the abdominal wall twice daily. Allograft rejection was defined as the loss of palpable contractile activity, and was confirmed by direct inspection at laparotomy. The MGD/Fe complex was prepared fresh daily by dissolving MGD in distilled water and then adding an appropriate amount of aqueous FeS0 4 to create a solution with a molar ratio of MGD/Fe of -10:1. A sufficient volume of the MGD/Fe solution was prepared to allow subcutaneous injection. A stock solution of Cyclosporin A (CsA, Sandoz Pharma Ltd.) was prepared in commercially available olive oil. Animals received 2.5 mg/kg intramuscularly on post- operative days one to seven. This suboptimal dose ("low- dose") of CsA was used to achieve prolongation of allograft survival, without the indefinite survival which typically results when a full dose of CsA (i.e., -10-15 mg/kg/day) is administered to the rat. Lewis rat strain recipients received a Wistar- Furth allograft and one of the following treatments: (1) single therapy with MGD-Fe (400 mg/kg, sc, bid) until rejection, or (2) low-dose cyclosporin A (CsA, 2.5 mg/kg im) for seven days, or (3) combination therapy with CsA (at the same low-dose level as used in (2)) for seven days and MGD-Fe (at the same dose level as used in (1) ) for 30 days. Body weight was used as an index of overall animal health during the study period. There was no difference in body weights at the beginning of the study, relative to the termination of the study in any of the study groups (see Table 2) . Results are expressed in the Table as mean ± SEM. Table 2 Body Weight, q Group n Preoperat:ive Rejection 1 (Isograft) 5 289±11 305±7 2 (Allograft, No treatment) 14 264±9 251±6 3 (Allograft, MGD-Fe) 17 243±5 234±5 4 (Allograft, CsA) 18 268±4 276±3 5 (Allograft, CsA + MGD-Fe) 11 267±7 297±8 takt ≥n at day 30 since the isograft does not undergo rejection In all of the study groups, there was a decrease in body weight of 8-14% by day 7 after transplant. All groups, however, displayed a weight gain after day seven, suggesting that the initial weight loss during the study period was due to the effect of surgery upon the rats, rather than the form of treatment to which the rats were subjected. Isograft controls which received no treatment exhibited similar weight trends as compared to the various treatment groups. The increase in body weight observed in the group subjected to invention combination therapy is likely the result of increased survival in the study due to improved graft survival. Graft survival is reported herein as the mean survival time (MST±SE) in days (see Table 3) . Table 3 Acute allograft rejection occurred in 6.9±0.2 days in untreated controls. Single drug therapy with either MGD-Fe or CsA alone significantly prolonged allograft survival, compared to untreated allografts (11.8±0.4 and 14.5±1.1 days, respectively) . Combination drug therapy according to the invention, however, resulted in a dramatic prolongation of graft survival (i.e., 45.0±4.7 days). MGD-Fe therapy was discontinued on day 30 post- transplant to determine whether indefinite survival (i.e., >100 days) was achievable. Graft function continued beyond 30 days in all 11 rats in the group receiving invention combination therapy (see Table 3) . One of the rats in this group has a functioning allograft more than 50 days following cessation of combination therapy. All animals appeared healthy throughout the duration of the therapy, and there were no deaths. In conclusion, modulation of nitric oxide levesl, especially in combination with subtherapeutic doses of standard immunosuppressive therapy, results in a dramatic prolongation of allograft survival. While the invention has been described in detail with reference to certain preferred embodiments thereof, it will be understood that modifications and variations are within the spirit and scope of that which is described and claimed.
