Description of the Invention: [Technical Field] The present invention relates to a virus which combines an activity enhancer of a nucleic acid analog containing a branched amino acid, a branched amino acid and a nucleic acid analog Hepatitis prevention or treatment agent 'viral hepatitis medicine, etc. [Prior Art] Hepatitis B virus (hereinafter also referred to as "HBV") belongs to the Hepadnavirus family of hepatic viruses (〇rthohepadnavirus), which is a virus that causes hepatitis B, mainly by blood media, mother and child (vertical ), sexual behavior (level) infection. Its persistent infection lacks self-conscious symptoms, but it can cause chronic hepatitis. Then the fibrosis of the liver is slowed down, so that cirrhosis may occur, and even liver cancer may occur. On the other hand, in the case of infection with hepatitis B virus, it is theoretically difficult to completely repel the virus, and antiviral therapy is used to reduce the virus, in order to maintain liver function while inhibiting the occurrence of liver cirrhosis or liver failure, and preventing the occurrence of liver cancer. is very important. Lamivudine is developed as an active ingredient of an antiviral agent for a therapeutic drug of HBV, and is a representative component of a nucleic acid analog preparation having a nucleoside-like structure. Lamivudine is known to initially exhibit an antiviral effect on the AIDS virus, but also exhibits a proliferation inhibitory effect on HBV. The mechanism of action of lamivudine on HBV is that the lamivudine phosphorylated by the triphosphate derivative hinders the reverse transcriptase of HBV and is incorporated into the DNA strand of the virus, thereby causing its elongation to stop (see Non-patent) Document 1). A nucleic acid analog such as Lamebine-5-201113023, which can be used in the form of an oral preparation, has few side effects, and has an antiviral activity equal to or higher than that of interferon. However, in suspending such administration In the case of a nucleic acid analog preparation, there is a problem that the probability of re-proliferation of the virus is high. In order to avoid re-expansion after discontinuation of administration, it is necessary to semi-permanently administer nucleic acid analogs. However, even if administered for a long period of time, the effect is at the apex of the early stage. In addition, resistant viruses are produced due to long-term administration, or medical costs are increased. A number of shortcomings. Furthermore, long-term investment in young people has concerns about the reproductive system. In addition, in the B-type TF inflammation zone, the frequency of activity reduction of hepatitis is naturally observed over time, so especially for young people, early administration and long-term administration of nucleic acid analogs are also available. May become over-medical. From such a point of view, the combination therapy with other drugs is being widely studied as a treatment strategy aimed at drug free and long-term remission (see Non-Patent Document 2). Interferon (hereinafter referred to as "IFN") is a drug that exerts its effects through direct antiviral action and activation of host immunity. Interferon has a variety of side effects such as headache, joint pain, and the like, and the medical expenses are expensive (see Non-Patent Document 3). However, the seroconversion phenomenon or the silencing of viral DNA may continue to occur for a long-term advantage (see Non-Patent Document 4). ), and a powerful choice for long-term relief. However, although the combination of PEG interferon and a nucleic acid analog has an effect of preventing the production of a resistant virus, there is a literature suggesting that the therapeutic effect is not different from the case of using interferon alone (see Non-Patent Documents 5 to 7). Therefore, in addition to IFN, there is a need for a drug that can be used with a nucleic acid analog and that enhances the therapeutic effect -6 - 201113023. It has been reported in the literature that when a branched amino acid is used for IFN therapy, the blood concentration is lowered (see Non-Patent Document 8). Further, it has been reported in the literature that branched-chain amino acids have an effect of enhancing the effect of IFN or attenuating the side effects of IFN (see Patent Document 1). However, the branched amino acid has a function of enhancing the antiviral action of the nucleic acid analog, and has not been clarified until now.

In addition, it also includes the results of reducing the virus: a decrease in the amount of HBV RNA in the blood, an improvement in serum albumin oxime, an improvement in ALT/AST 値, a shortened treatment time, and a decrease in the amount of nucleic acid analog administered. , nucleic acid analogs to treat patients with significant improvements in treatment efficiency, and the like. Among HBV-positive patients, in the case of chemotherapy for patients with malignant tumors, there is a concern about the onset of severe and violent hepatitis due to rapid proliferation and reactivation of the virus. When a chemotherapeutic agent is administered, the replication of the viral gene is directly promoted, so that the present invention can be administered prophylactically -16 " 201113023 sexual enhancer. In addition, by increasing the activity of the nucleic acid analog, in particular by administering the activity enhancer of the present invention for a long period of time after chemotherapy for a certain period of time, the HBV-DNA (which can be monitored by PCR or TMA) ) It also has an effect on continuous negatives. Here, "nucleic acid analog treatment" means that an antiviral action is exerted by a nucleic acid analog having antiviral activity, and as a result, a viral disease is treated by inhibiting proliferation of a virus or reducing a virus. By treating with a nucleic acid analog, for example, in the case where the viral disease is viral hepatitis, viral hepatitis is treated not only by inhibiting the proliferation of hepatitis virus or by reducing the hepatitis virus, but further, due to viral hepatitis. In terms of cirrhosis and liver cancer, it also exhibits antiviral activity against residual viruses, and can delay the progression from viral hepatitis to cirrhosis and liver cancer. Therefore, the "environment enhancer for nucleic acid analog having antiviral activity" of the present invention can be used not only for, for example, viral hepatitis, but also for preventing liver cirrhosis and liver cancer caused by viral hepatitis, or inhibiting the evolution thereof. . In addition, if it is changed from viral hepatitis to cirrhosis and liver cancer, the choice of liver cancer treatment will be limited by the liver reserve function of the background liver disease. Therefore, the focus is on recovering liver function as much as possible. Subsequent treatment options have become wider. Therefore, the activity enhancer of the present invention can be combined with a nucleic acid analog and used as an agent for improving liver reserve function. The "nucleic acid analog treatment" includes not only the case of treatment with a single nucleic acid analog, but also the case of treatment with a plurality of nucleic acid analogs or treatment with a nucleic acid analog and other agents. -17- 201113023 As an example of such an application, for example, a combination of a nucleic acid analog and an IFN-acting substance described in the pamphlet of International Publication WO2007/0 1 3677, or a combination of different nucleic acid analogs can be cited. The activity enhancer of the present invention is applicable to a subject having a nucleic acid analog administered to a wart. If the administration of the nucleic acid analog is suspended, the probability of proliferation of the hepatitis virus is high, and the effect of the nucleic acid analog preparation itself reaches a certain threshold (see, for example, "Clinical and Pharmaceutical Health" June 1999 issue" 5 Figure 6 on page 63). In such a case, by continuously administering the nucleic acid analog, in combination with the activity enhancer of the present invention, the effect of the nucleic acid analog preparation reaching the limit can be further enhanced. Alternatively, for a subject to be administered a nucleic acid analog preparation, the activity enhancer of the present invention is administered prior to administration of the nucleic acid analog, whereby the effect of the nucleic acid analog preparation to be administered later can be further enhanced. In particular, in the case of administering a nucleic acid analog preparation alone, the effect may reach a certain threshold, and by first administering the activity enhancer of the present invention, the effect reaches the bottom limit and the nucleic acid is similar. The effect of the preparation is enhanced. At this time, it is desirable to continue to administer the activity enhancer 8 of the present invention after administration of the nucleic acid analog. With regard to the period in which the activity enhancer of the present invention is administered, as long as it is an industrial person, the desired nucleic acid can be appropriately selected. The appropriate period of time required for the effect of the analog formulation. For example, the activity enhancer of the present invention is administered to the subject for administration for 12 years per day for 12 years, and thereafter the activity enhancer of the present invention is administered in the same manner, and the administration of the nucleic acid analog preparation such as entecavir hydrate is administered one day. 〇· 5 mg (based on entecavir). -18- 201113023 The subject here is not particularly limited and can be used as a target for all mammals, but should be human. The activity enhancer of the present invention can be administered as a pharmaceutical together with the above-mentioned nucleic acid analog preparation. This pharmaceutical product has a stronger therapeutic effect on nucleic acid analogs than a pharmaceutical product which has been used as an active ingredient in a nucleic acid analog preparation. Further, the activity enhancer of the present invention can be supplied not only in the form of administration of the above-mentioned agent or pharmaceutical product but also in various forms such as a functional food or a health food (including a dip) or a specific health food. The activity enhancer of the present invention can be produced orally by adding a branched amino acid to a raw material of a food or beverage. In the case where the activity enhancer of the present invention is administered in the form of a functional food or a health food or a specific health food, the food itself is prepared in the same manner as the usual mash food composition except for the addition of the branched amino acid. For the form of the food and beverage composition, a beverage such as a refreshing beverage, a carbonated beverage, a nutritional beverage, a fruit juice beverage, or a lactic acid bacteria beverage (a concentrated stock solution containing the same and a powder for conditioning); ice cream, sherbet, and Ice fruit such as shaved ice; sugar, chewing gum, candy, bubble gum, chocolate, sugar ingots, snacks, biscuits, jellies, jams, whipped cream, baking snacks, etc.; processed dairy products, milk drinks, fermented milk, cream and other dairy products; Bread; enteral nutrition food 'flow food, milk for child care, sports drinks; other functional foods. The shape of the food or drink may, for example, be an ingot or a granular supply. Therefore, the control of the daily meal amount and the calorie intake is not necessary to control the relationship with the intake of the activity enhancer of the present invention -19- £201113023 and the intake of other foods. Further, by preparing the form of the mash composition in advance, the amount of the activity enhancer can be accurately grasped. As long as it is an industrial person, it is possible to appropriately adjust the amount of branched amino acids contained in the foods in consideration of the disease, the age, sex, body weight, and the like of the subject. As an example of such a food, 3.2 g of a branched amino acid having a weight ratio of isoleucine, leucine, and valine acid of 1:2:1 is used as an activity enhancer, and further contains a vitamin. With a trace element such as zinc, the amount of granular food is 4g per dose. Further, it is also possible to mix only 5 to 3 g of isoleucinate as a branched amino acid to prepare a nutrient composition such as a liquid food. Further, the present invention provides a method of administering a nucleic acid analog having antiviral activity to a subject based on the following step (1); (2) an effective amount selected from the group consisting of isoleucine and leucine And the step of administering at least one branched amino acid of proline to the subject thereof; and enhancing the activity of the nucleic acid analog having antiviral activity. At this time, it is desirable to carry out the step (2) while the step (1) is continued. In the step (1), even if the nucleic acid analog is continuously administered, the effect has reached the apex, so the step (2) is carried out while the step (1) is continued, whereby the step (1) is administered. The activity of the nucleic acid analog is further enhanced to more effectively reduce the virus (e.g., hepatitis virus). Alternatively, it is desirable to carry out step -20-201113023 (η in the state in which the above step (2) is continued. In the case where only step (1) is carried out, even if the nucleic acid analog is continuously administered, the effect has reached a peak. Therefore, the step (2) is carried out first, and the step (1) is carried out while the step is continued, whereby the activity of the nucleic acid analog administered in the step (1) is further enhanced, and the virus can be more effectively made (for example). In addition, in the case of temporarily interrupting the treatment of the already started nucleic acid analog, the possibility of re-proliferation of the virus is high, and it is necessary to continue to administer the nucleic acid analog for a long period of time. However, the subject is often plagued by side effects caused by the administration of nucleic acid analogs due to long-term continuous administration (eg, red blood cell reduction, leukopenia, thrombocytopenia, depression, disturbance of consciousness, dysplastic anemia, difficulty breathing, incomplete veins, Omental disease, fever, burnout, headache, loss of appetite, hair loss, joint pain, etc.) The activity enhancer of the present invention can obtain the same effect as the nucleic acid analog in a smaller amount than in the case of using it alone, and as a result, the relative dose of the nucleic acid analog itself in the entire preparation can be reduced. Therefore, in the case of using the nucleic acid analog of the activity enhancer of the present invention, it can also be used as a side effect mitigating agent for the nucleic acid analog. Further, by using the activity enhancer of the present invention, the nucleic acid analog can be administered for a long period of time. Therefore, the possibility of the emergence of a resistant virus becomes low. Therefore, the activity enhancer of the present invention can also be used as a suppressor of the presence of a nucleic acid analog as an inhibitor of the emergence of a resistant virus. The hepatitis virus of the subject may be exemplified by all known hepatitis viruses, and among them, hepatitis A virus-21 - 201113023 is preferred. As described above, the activity enhancer of the present invention contains a substance selected from the group consisting of isoleucine, At least one branched amino acid of leucine and valine, based on the discovery that the branched amino acids enhance the activity of the nucleic acid analog An activity enhancer of the present invention, that is, a combination of at least one branched amino acid selected from the group consisting of isoleucine, leucine and valine and a nucleic acid analog having antiviral activity, As a prophylactic or therapeutic agent for viral hepatitis, it is more active against viral hepatitis than a nucleic acid analog alone. Therefore, the present invention also provides a pre-anti- or anti-therapeutic agent for viral hepatitis (described below) The "prophylactic or therapeutic agent of the present invention" is a combination of at least one branched amino acid selected from the group consisting of isoleucin acid and valine and a salt thereof, and a nucleic acid analog having antiviral activity. The prophylactic or therapeutic agent of the present invention may contain any branched or branched amino acid of at least one of isoleucine, leucine and valine, and may be, for example, iso-amino acid. All of leucine, leucine and valine are preferred. As long as it is an industrial person, it is possible to appropriately adjust the content ratio (weight ratio) of such branched amino acids in accordance with the state of the target, and the weight ratio of isoleucine, leucine, and valine Take 1: 1~3: 0.5~2.0 for better. In addition, the weight ratio of isoleucine, leucine and valine is 1:1.5~2·5: 〇·8~1.5 is particularly good, and the optimum weight ratio is 1:2:1.2 〇Prevention of the present invention The therapeutic agent may further contain a general formulation carrier described in the activity enhancer of the present invention. As long as it is a person in the industry, it is possible to adjust the content of the carrier for these preparations appropriately -22-201113023. The hepatitis virus which is a prophylactic or therapeutic agent of the present invention is not particularly limited, and all known hepatitis viruses are exemplified, and hepatitis B virus is preferred. By using the prophylactic or therapeutic agent of the present invention, viral hepatitis caused by such hepatitis viruses can be prevented or treated. The prophylactic or therapeutic agent of the present invention may contain a well-known antiviral component in addition to the above-mentioned branched amino acid and a nucleic acid analog having antiviral activity. As such an antiviral component, for example, IFN can be mentioned. As long as it is an industry person, the content of the antiviral component can be appropriately adjusted. The prophylactic or therapeutic agent of the present invention can inhibit viral hepatitis by enhancing the activity of a nucleic acid analog having antiviral activity. Specifically, the prophylactic or therapeutic agent of the present invention can inhibit the proliferation of hepatitis virus and can reduce the hepatitis virus. Therefore, the prophylactic or therapeutic agent of the present invention may be mixed with a pharmacologically acceptable carrier, and a pharmaceutical composition for viral hepatitis (for example, an injection, a granule, a granule, a fine granule, a powder, a capsule, or a cream) , the use of the form of suppositories, etc.). The pharmaceutical or pharmaceutical composition can be administered orally or parenterally (e.g., topically, rectally, intravenously, etc.), preferably by oral administration. As the pharmacologically acceptable carrier to be used, there are, for example, lactose, glucose, D. mannitol, starch, crystalline cellulose, calcium carbonate, kaolin, gelatin, hydroxypropylcellulose, hydroxypropylmethylcellulose. , polyvinylpyrrolidone, ethanol, carboxymethyl cellulose, carboxymethyl cellulose calcium salt, magnesium stearate, talc, ethyl ketone cellulose 'white sugar, titanium oxide, benzoic acid, hydroxybenzoic acid ester, off Sodium hydroacetate, gum arabic, tragacanth, methyl fiber-23- 201113023 Vitamin, egg yolk, surfactant, monosaccharide syrup, citric acid, distilled water, glycerin, propylene glycol, polyethylene glycol, sodium monohydrogen phosphate, phosphoric acid Such functions as sodium dihydrogen, sodium phosphate, sodium chloride, phenol, thimerosal, sodium hydrogen sulfite, etc. have been known to those skilled in the art. These systems are used in the form of a pharmaceutical or pharmaceutical composition of the present invention depending on the form of the preparation. As long as it is an industrial person, the contents of the supports can be appropriately adjusted. In the case of the activity enhancer, the side effect mitigator, the prophylactic or therapeutic agent, the pharmaceutical and the pharmaceutical composition of the present invention (hereinafter referred to as "the agent, the pharmaceutical and the pharmaceutical composition of the present invention"), the branched amine The amount of base acid to be administered (intake amount) varies depending on the morbidity, age, administration method, etc. of the patient, and is usually 0.5 to 30.0 g of leucine 0.5 to 60.0 g per person per day. , valine acid 0.5~30.Og. In the case of an adult, it is preferably 2.0 to 1 〇g of leucine, 3.8 to 20.0 g of leucine, 2.0 to 10 g of valine, preferably 2.5 to 3.5 of isoleucine per person per day. g, leucine 5.0 to 7. 〇g, valine acid 3.0 to 4.0 g. In the above-mentioned agent, pharmaceutical, and pharmaceutical composition of the present invention, all of the isoleucine, leucine, and lysine are contained, and the daily dose of the adult is the total amount of the three branched amino acids. Usually, it is preferably about 2.0 to 50.0 g, and it is divided into 1 to 6 times (preferably 1 to 3 times) as necessary. In contrast, the administration amount of the nucleic acid analog varies depending on various types of the nucleic acid analog to be administered, the pathology of the patient, the age, the administration method, and the like, and the amount of the adult one day is usually O.Oml. ~100mg or so, preferably about 0.1 mg~10Omg. Especially in patients with renal dysfunction (patients undergoing hemodialysis, etc.), it is necessary to reduce the amount of administration. The amount of adult -24-201113023 for one day is about 〇.1mg~1〇mg. For example, among patients with hepatitis B virus-positive disease, among patients with cirrhosis who do not have liver cancer, one day-time, on the fasting, 0.5 mg of entecavir hydrate (based on entecavir) (and all three branched-chain amino acids) It is preferred that all of the amino acid preparations (3 to 4 g in terms of the amount of branched amino acid) are administered three times a day. In the agent, the pharmaceutical and the pharmaceutical composition of the present invention, the branched amino acid and the nucleic acid analog may be separately prepared into individual preparations, administered in the same or different administration form, or the branched amino acid may be Nucleic acid analogs are administered as a blending agent contained in the same formulation. In the case where the branched amino acid and the nucleic acid analog are each a different preparation, or in the case of being blended in the same preparation, the branched amino acid administered per time in the above-mentioned agent, pharmaceutical and pharmaceutical composition of the present invention The blending amount is usually about 〜5 to 50.0 g, preferably about 1.0 to 20-〇g, preferably about 2.0 to 6.0 g. Further, the amount of the nucleic acid analog administered per administration is set in accordance with each agent. For example, among patients with hepatitis B virus-positive disease, among patients with liver cirrhosis who do not have liver cancer, once a day, entecavir hydrate 〇. 5 mg (in entecavir) is administered on an empty stomach, and three kinds of branched amino groups are used. The amount of branched amino acid administered per time for the acid-containing acid preparation contained in the acid is 3 to 4 g (it is preferable to administer it three times a day). In the above-mentioned agent, pharmaceutical, and pharmaceutical composition of the present invention, a case where a branched amino acid is combined with each of the preparations of the nucleic acid analog of the present invention, in terms of the order in which the combination is administered, It is not particularly limited, and as long as it is an industrial person, an appropriate order and time difference can be selected in accordance with an administration form, a administration method, and the like which can obtain an appropriate nucleic acid analog administration effect-25-201113023. Examples of the administration sequence and the time difference include a method of administering a nucleic acid analog within 5 minutes to 2 years after administration of a branched amino acid, for example, when a branched amino acid is administered first. On the other hand, a method of administering a branched-chain amino acid, for example, within 5 minutes to 2 years after administration of the nucleic acid analog, in the case where the nucleic acid analog is administered first, may be mentioned. In the case where a branched amino acid is administered first, it is desirable to continuously administer a branched amino acid after the start of administration of the nucleic acid analog. On the other hand, in the case of first administering a nucleic acid analog, it is desirable to continuously administer the nucleic acid analog according to the formulation described in the attached file of each preparation, and further, it is desirable to continue the nucleic acid analog after the start of administration of the branched amino acid. Cast. When the dosage (intake amount) of the branched-chain amino acid of the active ingredient of the agent, the pharmaceutical, and the pharmaceutical composition of the present invention is calculated, the object of the present invention is effective, and the agent used for the purpose of prevention, treatment, and the like of the disease is effective. In terms of ingredients, the range of blending amount per administration is determined in the manner described above, and thus for purposes different from the present invention, for example, for the purpose of normal foraging life, or for the purpose of treating other diseases, or The branched chain amino acid to be administered is not necessarily included in the aforementioned blending amount. For example, it is not necessary to calculate the amount of branched-chain amino acid taken in a day of normal eating life from the amount of administration of the active ingredient in the present invention for one day. Further, the present invention provides a commercial package comprising: at least one branched amino acid selected from the group consisting of isoleucine, leucine and valine, or a salt thereof, and the branched amino acid or The salt may be used or used to enhance the activity of the nucleic acid analog having antiviral activity, and the description of the branched chain amine-26-201113023 base acid or its salt is described. [Examples] Next, the present invention will be described in further detail by way of examples. Further, the following examples are specifically described with reference to an example of the present invention, and the present invention is not limited thereto.

The nucleic acid amplification test is performed by either the PCR method or the TMA method depending on the amount of virus in the patient (measurement range: 2.6 to 7.6 log.copies/mL (PCR method), 3.7 - 8.7 LGE/m L (TM) Method A)). LGE, which means Logarithm genome equivalent, is actually the same as log.copies. Calculate the amount of change before use for each patient (for Group A (horizontal strips in Figure 4), before the administration of the drug) - the combination of the Livact particles is administered to the type B. The impact of the reduction in hepatitis virus is analyzed. The results are disclosed in Figure 4. In Fig. 4, group A will subtract the same amount of HBV DNA 値' at 3, 6, and 12 months after the start of administration of the nucleic acid analog preparation alone, the same sputum before starting the same preparation. It is expressed on the vertical axis (n=ll) °B group (black -29 - 201113023 strip in Fig. 4), which is based on the HBV DNA 测定 measured after one year of administration of Livact granules, and thereafter the nucleic acid is similar. When the combined preparation of the preparation was administered, the difference of the standard 値 was subtracted from the amount of the virus (n=3). (: group (white strip in Fig. 4) is the opposite of group B, indicating the difference in the case of administration of Livact particles after administration of the nucleic acid analog preparation for one year. (Patient group) Group A: alone Patient group (n=ΐι) administered to the nucleic acid analog preparation Group B: After administration of Livact particles for 1 year, the Livact particles were continuously administered, and the nucleic acid analog preparation was started to be administered, and the same preparation was continuously administered for one year. Patient group (n=3), (: group: 1 year after the administration of the nucleic acid analog preparation alone, the same preparation was continuously administered, and the Livact granules were started at the same time, and the patient group who continued to administer Livact granules for 1 year (n =6) As shown in Fig. 4, in the case where the nucleic acid analog preparation was administered alone, the amount of virus was decreased in the same formulation for 3 months, and the effect was not significantly increased even after continuous administration for 1 year. In the case of the B group administered with the nucleic acid analog preparation in the case of the patient who has administered the Livact particles for one year, the amount of the virus tends to be lowered as compared with the case where the nucleic acid analog preparation is administered alone, and if When the period of the joint investment became 1 year, it was observed. The low amount maintains a certain or even a tendency to reduce the amount of virus. If the group C is observed, it is found that after the virus reduction effect of the nucleic acid analog occurs, even if the Livact particle is used, no significant reduction in the amount of the virus is observed. Continuing -30-201113023 When Livact granules were administered for 1 year, a tendency to reduce the amount of virus was observed compared with the time point of sputum use for 3 months. [Industrial Applicability] According to the present invention 'by continuous administration The activity of the nucleic acid analog preparation reaching the bottom limit can be further enhanced. Thereby, the liver reserve function is improved compared with the case of using the nucleic acid analog preparation alone, so the choice of liver disease treatment method including liver cancer is selected. The present invention is effective in view of the above. Further, by the present invention, a prophylactic or therapeutic agent for viral hepatitis which is more potent than a conventional nucleic acid analog, and a therapeutic for viral hepatitis can be obtained. Further, according to the present invention, the virus growth inhibitory effect of the nucleic acid analog preparation can be stably maintained for a long period of time. In addition, the hepatitis B virus is positive. There is a concern of acute exacerbation and rapid outbreak, and in the case of administering a nucleic acid analog preparation after the onset, there are many cases in which the prognosis is poor. In this case, the present invention can be improved particularly in the prophylactic administration before the aforementioned acute outbreak. In addition, in the case of chemotherapy, immunotherapy, and transplantation therapy, if an anticancer agent or an immunosuppressive agent is used, there is a case where the hepatitis B virus rapidly proliferates, and the nucleic acid analog preparation is prevented from being administered before each therapy is administered. The present invention is also effective. 6P3 This application is based on Japanese Patent Application No. 20 09-150296 (Application Date: June 24, 2009) and Japan Special Purpose 2010-040423 (Application Date: 2010 2) Based on the 25th of the month, all of these contents are included in £–31 - 201113023 in this specification.
