Background Art

[0002] Zinc plays various roles depending on various pathological conditions and states, and accordingly is easily consumed and easily falls into a deficient state. Pathological conditions caused by zinc deficiency include sexual immaturity and growth retardation, oligospermia, amenorrhea, anemia, reduced immune function, liver damage, night blindness, hair loss and dermatitis, anorexia, taste disorder / abnormality, olfactory disorder, chronic diarrhea, delayed wound healing, mental / behavioral abnormalities, and various other symptoms. For such zinc deficiency states, in foreign countries, various zinc preparations such as zinc sulfate and zinc gluconate have been approved and sold as "zinc deficiency", "treatment of zinc deficiency states that cannot be solved by diet", "acrodermatitis enteropathica", "zinc supplementation", etc., although there are differences depending on the country. As domestic zinc preparations, Novergin (registered trademark, Novartis Pharma Co., Ltd., hereinafter the same) tablets 25 mg, Novergin tablets 50 mg, and Novergin granules 5% have obtained the efficacy and effect for hypozincemia and are on sale. All of these are preparations containing zinc acetate.

[0003] ​​​​​​​​​​​​​​。Regarding the usage of the noveldine preparation, in consideration of gastrointestinal side effects such as nausea and vomiting, which are the main side effects, the dose per administration is reduced and it is administered twice or three times a day.

[0004] As a preparation containing histidine zinc as an active ingredient, Zinkamin - Falk 15mg hard capsules are known. This preparation is for the treatment of clinically confirmed zinc deficiency ( when improvement is not seen by dietary therapy), and adults take one capsule corresponding to 15 mg of zinc one tablet per day, one hour before a meal (Non - Patent Document 1). However, a therapeutic agent for hypozincemia containing histidine zinc as an active ingredient, and a therapeutic agent for hypozincemia with a specific usage and dosage that can effectively treat hypozincemia were not known.

MODE FOR CARRYING OUT THE INVENTION

[0012] The therapeutic agent for hypozincemia of the present invention contains histidine zinc, or a pharmaceutically acceptable salt or solvate thereof. Examples of histidine zinc, or a pharmaceutically acceptable salt or solvate thereof include, for example, histidine zinc dihydrate (JAN: histidine zinc hydrate). Histidine zinc, or a pharmaceutically acceptable salt or solvate thereof, is a compound in which histidine and zinc ions are complexed.

[0013] In the present specification, "treatment of hypozincemia" means maintaining the serum zinc concentration of a hypozincemia patient within the normal range (also referred to as the "target serum zinc concentration"). According to the "Diagnostic Guidelines for Zinc Deficiency 2018" edited by the Japanese Society for Clinical Nutrition, a person with a serum zinc concentration of less than 60 μg / dL is defined as having zinc deficiency, and a person with a concentration of 60 or more and less than 80 μg / dL is defined as having potential zinc deficiency. For example, the "target serum zinc concentration" in the present invention has a lower limit of 80 μg / dL, and the upper limit value can be less than 250 μg / dL, more preferably less than 200 μg / dL, which is considered to have a low possibility of causing adverse effects on the body. Also, the "diagnosis of zinc deficiency" edited by the Japanese Society for Clinical Nutrition. According to this, a person with a serum zinc concentration of less than 60 μg / dL is defined as having zinc deficiency, and a person with a concentration of 60 or more and less than 80 μg / dL is defined as having potential zinc deficiency. For example, the "target serum zinc concentration" in the present invention has a lower limit of 80 μg / dL, and the upper limit value can be less than 250 μg / dL, more preferably less than 200 μg / dL, which is considered to have a low possibility of causing adverse effects on the body. Also, the "diagnosis of zinc deficiency" It may be 80 - 130 μg / dL, which is recommended in the "Treatment Guidelines 2018". That is, the "target serum zinc concentration" in the present invention is, for example, (1) 80 μg / dL or more, (2 ) 80 μg / dL or more and less than 250 μg / dL, (3) 80 μg / dL or more and less than 200 μg / dL, or (4) 80 μg / dL or more and 130 μg / dL or less.

[0014] The therapeutic agent of the present invention can be administered orally once a day after a meal. Administering once a day makes it easier to maintain medication as prescribed and can improve medication adherence. In particular in the treatment of hypozincemia, since it is necessary to maintain the target serum zinc concentration, it is important that the patient can take the medicine as prescribed without forgetting to drink or making dosage errors.

[0015] The serum zinc concentration can be measured by a known method. For example, in addition to the method by atomic absorption spectrometry , for example, the absorbance of the serum of the subject colored with a reagent such as Accuriad (registered trademark) Zinc (manufacturer: Nobel Pharma Co., Ltd.) is measured using an analyzer such as Accuriad (registered trademark) (manufacturer: Nobel Pharma Co., Ltd.) to obtain the result.

[0016] The starting dose of the therapeutic agent of the present invention for adults and children weighing 30 kg or more can be set at 50 - 100 mg of zinc per dose. The starting dose can be adjusted according to the patient's serum zinc concentration. For example, when the serum zinc concentration is 50 μg / dL or more, it can be 50 mg / day of zinc. The administration period at the starting dose in this case can be, for example, 4 weeks . Also, when the serum zinc concentration is less than 50 μg / dL, 1 mg of zinc per dose... ​It can be 00 mg / day. The administration period at the starting dose in this case can be, for example, 4 weeks and can be done.

[0017] The therapeutic agent of the present invention can be appropriately increased or decreased within the range not exceeding 150 mg of zinc per day according to the serum zinc concentration and the patient's condition. Specifically, for example, in adults and children weighing 30 kg or more, as zinc, 50 - 100 mg can be used as the starting dose and administered orally once after each meal of the day. Alternatively, it can be administered orally at a dose that maintains the serum zinc concentration at the target serum zinc concentration (for example, 80 μg / dL or more and less than 200 μg / dL). More specifically, for example, while continuing the administration, the serum zinc concentration is measured every certain period (for example, 4 weeks), and if it is less than the target serum zinc concentration (for example, less than 80 μg / dL), the dose is increased by 50 mg / day of zinc, and administration can be continued for a further certain period (for example, 4 weeks). Also, if the serum zinc concentration is equal to or higher than the target serum zinc concentration (for example, 200 μg / dL or more ), the dose is decreased by 25 mg / day of zinc, and administration can be continued for a further certain period (for example, 4 weeks ). In addition, when the serum copper concentration is below a certain value (for example, 30 μg / dL), from the viewpoint of preventing copper deficiency, the dose is decreased by 25 mg / day of zinc, and conditions such as stopping the administration when the value is lower (for example, less than 10 μg / dL) can also be used. ) can be done. ) .

[0018] The maximum daily dose of the therapeutic agent of the present invention can be 150 mg of zinc.

[0019] The dosage form when the therapeutic agent of the present invention is administered orally is not particularly limited. For example, tablets such as plain tablets and film-coated tablets, orally disintegrating tablets, capsules, powders, granules, or dry syrups, etc.​​​​ It can be made into a syrup or a liquid preparation such as a syrup. By using such a dosage form, it becomes easier to take once a day while adjusting the dosage as needed. The preparations of these dosage forms can be produced by a conventionally known method. Once a day, and it becomes easier to take while adjusting the dosage as needed. The preparations of these dosage forms can be produced by a conventionally known method.

Further, it is more preferable that such an elution 15-minute value is 80% or more both at the start of storage and after 3 months when stored under storage conditions without packaging, for example, at 40°C, 75% RH, in an open system. Such characteristics indicate that the tablets of the present invention are tablets having stability in maintaining the content of the active ingredient even after storage for a predetermined period. and after 3 months.

[0065] The tablets of the present invention preferably have a smaller decrease rate (dissolution decrease rate) of the elution 15-minute value from the start of storage to 3 months later in the paddle method (test solution: water, rotation speed: 75 revolutions per minute). In particular, under storage conditions without packaging, for example, when stored at 40°C, 75% RH, in an open system, ​​​​The elution property at the start of storage and after 3 months in combination is 80% or more in both cases, and it is more preferable that the elution property reduction rate during this period is smaller.

[0066] The elution property reduction rate indicates the reduction rate of the 15 - minute elution value from the start of storage to 3 months later, and is a percentage value that can be calculated by the following formula as the reduction in elution property between the start of storage, that is, the 15 - minute elution value at the start of storage, and after 3 months. The elution property at the start of storage, that is, with respect to the 15 - minute elution value at the start of storage, It is a percentage value that can be calculated by the following formula as the reduction in elution property between the start of storage and after 3 months.

[0067] Elution property reduction rate (%) = [(Elution property at the start of storage) - (Elution property after 3 months)] / (Elution property at the start of storage) × 100

[0068] The lower the elution property reduction rate, the better the stability. The elution property reduction rate is preferably less than 15%, or more preferably less than 10%, still more preferably less than 8%, and even more preferably less than 6 %. % is more preferable.

[0069] The tablets of the present invention can be produced, for example, by the following method. Step 1: Granulating a mixture of an active ingredient (for example, histidine zinc hydrate), and one or more components selected from D - mannitol, sucrose, sorbitol, xylitol, corn starch, and potato starch, and crystalline cellulose to obtain a granulated product (granulation step), Step 2: Drying the obtained granulated product (drying step), and Step 3: Tableting the obtained granulated product to obtain a core tablet (tableting step). Step 2: Drying the obtained granulated product (drying step), and Step 3: Tableting the obtained granulated product to obtain a core tablet (tableting step).

[0070] Furthermore, when making coated tablets, it can be produced by a method including the following Step 4 following Step 3. Step 4: Film - coating the core tablet and then drying (coating). Step 4: Film - coating the core tablet and then drying (coating).

[0071] These steps are usually carried out in the order of Step 1 to Step 3, or Step 1 to Step 4, and may further include other steps. Examples of other steps include a sizing step, a mixing step, etc.

[0072] Step 1: Granulation step Step 1 can be carried out by, for example, a wet granulation method such as a stirring granulation method or a fluidized bed granulation method, or a dry granulation method. When using histidine zinc hydrate as the active ingredient, for example, a mixture of histidine zinc hydrate, and one or more components selected from D-mannitol, sucrose, sorbitol, xylitol, corn starch, and potato starch and crystalline cellulose is put into a granulator and mixed, and then water or an aqueous binder solution is added to the mixture by spraying or the like, and the mixture is mixed to obtain granules. After that, the obtained granules can be put into a sizing machine for sizing. Further, the sized granules can be dried using a dryer such as a fluidized bed dryer. Subsequent to Step 1, the obtained granules can be put into a sizing machine for sizing. Further, the sized granules can be dried using a dryer such as a fluidized bed dryer.

[0073] Step 2: Drying step Step 2 is a step for producing granules suitable for tableting in Step 3 by removing the solvent (for example, water) added in the granulation step. Step 2 can be carried out using a dryer such as a fluidized bed dryer. Specifically, the granules obtained in Step 1 are put into a dryer, and drying is carried out until the desired exhaust temperature is reached while controlling the weight loss on drying by the inlet air temperature and the exhaust temperature. If the weight loss on drying exceeds the control range, drying is repeated until the control range is reached. Here, when the active ingredient is histidine zinc hydrate, by setting the inlet air temperature to, for example, 60 °C and drying until the exhaust temperature reaches 32 °C, the moisture content suitable for tableting and the histidine of the raw material ​​​​​​​​​​​It is possible to obtain a dry granule that retains the water of hydration of histidine zinc hydrate. Histidine zinc hydrate has the property of losing the water of hydration (crystal water) and becoming anhydrous at high temperatures and low humidities. Therefore, if it is dried excessively (for example, if the product temperature exceeds 40 °C and continues for a certain period of time or more), it becomes difficult to maintain the appropriate amount of moisture for tableting.

[0074] Step 3: Tableting step Step 3 is a step of tableting the granule obtained in the previous step to obtain a core tablet. Tableting is performed by a compression molding mold, and at this time, additives may be further mixed. The compression molding method is not particularly limited, and for example, methods and apparatuses generally used for molding tablets, such as rotary tablet presses and single-shot tablet presses, can be used. Also, the conditions for this compression molding are not particularly limited as long as a core tablet can be obtained. In this step, tablets having a desired mass can be obtained.

[0075] Step 4: Coating Step 4 is a step of film-coating the core tablet and then drying it. The method of film-coating is not particularly limited, and a method generally used in the production of film-coated tablets can be adopted. Film-coating can be performed, for example, by using a coating machine to wet-spray coat a suspension of a coating agent and a solvent onto the core tablet. As the solvent, for example, water or alcohols such as ethanol and isopropanol can be used.

[0076] The drying following the film-coating is a step for drying the solvent of the coating agent, and is not particularly limited as long as the loss of the water of hydration in the active ingredient is suppressed. Conventionally, The drying method of the coating agent in the production of known tablets can be adopted.

[0077] For the tablets obtained by coating, a brightening agent or the like may be further applied by a conventionally known method. It may be applied.

The tablet contains histidine zinc, or a pharmaceutically acceptable salt or solvate thereof as an active ingredient, and has an elution value at 15 minutes of 80% or more in the paddle method (test solution: water, rotation speed: 75 revolutions per minute). In such an aspect, the elution value at 15 minutes in the paddle method (test solution: water, rotation speed: 75 revolutions per minute) is preferably 80% or more both at the start of measurement and after storage for 3 months when stored under the conditions of 40 ° C, 75% RH, open system. One or more components selected from, and crystalline cellulose, granulating step of granulating with a binder, drying step of drying the obtained granulated product, and a step of tableting the dried granulated product, obtained by, histidine zinc, or its pharmaceutical containing a pharmaceutically acceptable salt or solvate as an active ingredient, paddle method (test solution: water, rotation number: 75 revolutions per minute) tablets with an elution value of 80% or more at 15 minutes. In such an embodiment In, the elution value at 15 minutes in the paddle method (test solution: water, rotation speed: 75 revolutions per minute) is, for example when stored under the conditions of 40 ° C, 75% RH, open system, both at the start of measurement and after storage for 3 months It is preferably 80% or more.

It is understood that it can be carried out. It is understood that it can be carried out without departing from the scope or spirit of the present invention defined in the appended patent claims. It is understood.

[0080] Example 1: Single-dose study in healthy adult males (fasting / postprandial, 25 mg) ​A histidine zinc (N PC-25) capsule containing 25 mg of histidine zinc hydrate as zinc (hereinafter referred to as NPC-25 capsule) was used to conduct a single-dose administration test on healthy adult men under fasting and after meal administration For fasting administration, after fasting for 10 hours or more, together with 200 mL of water, an NPC-25 capsule (1 capsule) was administered. For after-meal administration, a high-calorie and high-fat meal was consumed within 20 minutes, and 30 minutes after the start of the meal an NPC-25 capsule (1 capsule) was administered orally as a single dose together with 200 mL of water (n = 12). Blood samples were collected at a total of 12 time points before administration, and 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0, 12.0, 21.0, and 24.0 hours after administration to measure the exogenous serum zinc concentration and observe the changes up to 24 hours later. The results are shown in Figure 1 Note that the "exogenous serum zinc concentration" indicates the change in serum zinc concentration from before the histidine zinc administration test (Points where the value became negative were judged as the disappearance of exogenous serum zinc, and the exogenous serum zinc concentration was recorded as 0.)

[0081] As can be seen from Figure 1, the average value of the exogenous serum zinc concentration during fasting administration reached a maximum value of 133.50 ± 34.46 μg / dL at 2 hours after administration and then decreased, and almost returned to the baseline value before administration at 8 hours after administration. During after-meal administration, in 4 out of 12 cases, the AUC (area under the serum drug concentration-time curve from 0 to 24 hours after administration) and C (maximum blood concentration) of the exogenous serum zinc concentration showed 0, and the average value of the exogenous serum zinc concentration was 2 .17 ± 6.59 μg / dL, which was the highest value at 3 hours after administration. That is, 25 m of NPC-25 capsule 0-24 (area under the serum drug concentration-time curve from 0 to 24 hours after administration) and C max (maximum blood concentration) of the exogenous serum zinc concentration showed 0, and the average value of the exogenous serum zinc concentration was 2 .17 ± 6.59 μg / dL, which was the highest value at 3 hours after administration. That is, 25 m of NPC-25 capsule ​​In the postprandial administration of g, compared with the administration under fasting, the AUCs were respectively about 0-24 0.02-fold and the C was about 0.03-fold at max . In the case of a single administration of 25 mg, the exogenous serum zinc concentration increased in the administration under fasting, but hardly increased in the postprandial administration. It can be seen .

[0082] Example 2: Single-dose study in healthy adult males (postprandial, 50, 100, 150 mg) Using NPC-25 capsules, a single-dose study was conducted in healthy adult males with the administered doses being 50 mg, 100 mg, and 150 mg as zinc respectively in the postprandial administration. A high-calorie high-fat meal was consumed within 20 minutes, and 30 minutes after the start of the meal, together with 200 mL of water, NPC-25 capsules (2 capsules for the 50 mg administration group, 4 capsules for the 100 mg administration group, 6 capsules for the 150 mg administration group) were orally administered once (n = 12). Blood samples were collected at a total of 12 time points before administration and at 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0, 12.0, 21.0, and 24.0 hours after administration to measure the exogenous serum zinc concentration, and the changes up to 24 hours were observed. The results are shown in Figure 2. The average value of the exogenous serum zinc concentration at the postprandial administration of 50 mg of NPC-25 capsules reached the highest value of 34.33 ± 21.58 μg / dL at 3 hours after administration and then decreased, and almost returned to the baseline value before administration at 8 hours after administration. The average value of the exogenous serum zinc concentration at the postprandial administration of 100 mg of NPC-25 capsules reached the highest value of 145.25 ± 37.18 μg / dL at 3 hours after administration and then decreased, and almost returned to the baseline value before administration at 8 hours after administration. The average value of the exogenous serum zinc concentration at the postprandial administration of 150 mg of NPC-25 capsules reached the highest value of 2 After reaching 39.92±42.75 μg / dL, it decreased and almost returned to the pre-dose baseline value 12 hours after administration. That is, in the case of postprandial administration, it can be seen that the exogenous serum zinc concentration significantly increases when at least 50 mg equivalent of the therapeutic agent according to the present invention as zinc is administered. Example 3: Repeated dose study 1 (50 mg) for healthy adult males Three types of repeated dose studies were conducted for healthy adult males (n = 8 for each dosing group). Venous blood of the subjects was collected at the specified times from before dosing to 15 days after the start of dosing on the 1st day of dosing, and the serum zinc concentration at each blood collection time point was determined. Based on the determined serum zinc concentration, exogenous pharmacokinetic evaluation parameters (AUC (area under the serum drug concentration-time curve from 0 to 24 hours after dosing), C (maximum blood concentration), C

[0083] (blood concentration immediately before dosing (C on the 1st day of dosing is the concentration immediately before dosing on the 2nd day of dosing, and C on the 14th day of dosing is the concentration on the 15th day of dosing (24 hours after dosing on the 14th day of dosing))), and t (time to reach the maximum blood concentration)) were determined. 0-24 (area under the serum drug concentration-time curve from 0 to 24 hours after dosing), C (maximum blood concentration), C max (blood concentration immediately before dosing (C trough on the 1st day of dosing is the concentration immediately before dosing on the 2nd day of dosing, and C on the 14th day of dosing is the concentration on the 15th day of dosing (24 hours after dosing on the 14th day of dosing))), and t trough (time to reach the maximum blood concentration)) were determined. The dosages and administration methods of each dosing group of NPC-25 and the Novergin dosing group were as follows. trough NPC-25 (50 mg / day) once-daily dosing group: Two NPC-25 capsules (50 mg as zinc) were repeatedly orally administered once a day for 14 days after meals. NPC-25 (50 mg / day) twice-daily dosing group: One NPC-25 capsule (25 mg as zinc) was repeatedly orally administered twice a day for 14 days after meals. max

[0084] NPC-25 Administration Group ​​​​​​Novergine Administration Group Novergin (50 mg / day) twice-daily administration group: Novergin tablets (25 mg each tablet, equivalent to 25 mg of zinc) were orally administered twice daily after meals for 14 days. For each administration group, the inter-group ratios of the exogenous pharmacokinetic evaluation parameters were calculated, and the differences in exogenous pharmacokinetics in each administration group were evaluated. The ratios of the mean values of the exogenous pharmacokinetic evaluation parameters (AUC

[0089] t max The ratios of the average values on the first day of administration and the 14th day of administration of were 1.1739 and 1.9600 respectively for the "NPC-25 (50 mg / day) twice-daily administration group vs Novergin (50 mg / day) twice-daily administration group", and 0.9348 and 0.9600 respectively for the "NPC-25 (50 mg / day) once-daily administration group vs Novergin (50 mg / day) twice-daily administration group". That is, t on the first day of administration in the NPC-25 (50 mg / day) twice-daily administration group was at the same level as the Novergin (50 mg / day) twice-daily administration group, and t on the 14th day of administration was slower compared to the Novergin (50 mg / day) twice-daily administration group. [[ID=2,3]]t max on the first day of administration in the NPC-25 (50 mg / day) once-daily administration group was at the same level as the Novergin (50 mg / day) twice-daily administration group, and t on the 14th day of administration max was slower compared to the Novergin (50 mg / day) twice-daily administration group. t max on the first day of administration and the 14th day of administration in the NPC-25 (50 mg / day) once-daily administration group were both at the same level as the Novergin (50 mg / day) twice-daily administration group.

[0090] From the above results, it can be seen that once-daily administration of 50 mg / day of zinc in NPC-25 (histidine zinc) has an effect equivalent to or greater than twice-daily administration of 50 mg / day of zinc in Novergin.

[0091] Example 4: Repeated-dose study 2 (100 mg) in healthy adult males Three repeated-dose studies were conducted on healthy adult males as follows (for each administration group, (n=8) Before administration and at specified times from the first day of administration to the 15th day of administration, Venous blood was collected from the subjects, and serum zinc concentrations were determined at each blood collection point. Based on the exogenous pharmacokinetic evaluation parameters (AUC 0-24 , C max , C trough , and t max ) was sought.

[0092] The doses and administration methods for each NPC-25 administration group and Nobelzin administration group were as follows. NPC-25 Administration Group NPC-25 (100 mg / day) once-daily administration group: 4 capsules of NPC-25 capsules ( The subjects were given 100 mg of zinc orally once daily after meals for 14 days. NPC-25 (100 mg / day) twice-daily administration group: 2 capsules of NPC-25 capsules ( The subjects were given 50 mg of zinc twice daily after meals for 14 days. Novergine Administration Group Nobelzin (100 mg / day) twice-daily administration group: Nobelzin tablets 25 mg x 2 tablets (as zinc) The subjects were given 50 mg of the drug twice daily after meals for 14 days. The intergroup ratios of each exogenous pharmacokinetic evaluation parameter obtained for each administration group were calculated, and Differences in exogenous pharmacokinetics between the treatment groups were evaluated.

[0094] AUC 0-24 The ratios of the mean values on the first day of administration and the 14th day of administration of "NPC-25 ( 100 mg / day) twice a day administration group vs. Novergin (100 mg / day) twice a day administration group" were 1.7264 and 1.3504 respectively, and in the case of "NPC-25 (100 mg / day) once a day administration group vs. Novergin (100 mg / day) twice a day administration group", they were 2.5295 and 1.5328 respectively. That is, the AUC on the first day of administration of the NPC-25 (100 mg / day) twice a day administration group 0-24 was higher than that of the Novergin (100 mg / day) twice a day administration group, and the AUC on the 14th day of administration was comparable to that of the Novergin (100 mg / day) twice a day administration group. On the other hand, the AUC on the first day of administration and the 14th day of administration of the NPC-25 (100 mg / day) once a day administration group 0-24 were both higher than those of the Novergin (100 mg / day) twice a day administration group. The ratios of the mean values on the first day of administration and the 14th day of administration of 0-24 C were 1.3269 and 1.1977 respectively in the case of "NPC-25 (100 m

[0095] C max g / day) twice a day administration group vs. Novergin (100 mg / day) twice a day administration group", and were 2.7825 and 2. respectively in the case of "NPC-25 (100 mg / day) once a day administration group vs. Novergin (100 mg / day) twice a day administration group". That is, the C on the first day of administration and the 14th day of administration of the NPC-25 (100 mg / day) twice a day administration group were both higher than those of the Novergin (100 mg / day) once a day administration group. The C on the first day of administration and the 14th day of administration of max the NPC-25 (100 mg / day) twice a day administration group It was comparable to the twice-daily administration group. On the other hand, for the once-daily administration group of NPC-25 (100 mg / day), C on the first day of administration and on the 14th day of administration max was higher in both cases compared to the twice-daily administration group of Novergin (100 mg / day ).

[0096] C trough The ratios of the average values on the first day of administration and on the 14th day of administration were "NPC-25 ( 100 mg / day) twice-daily administration group vs Novergin (100 mg / day) twice-daily administration group" and were 1.6810 and 1.1780 respectively, and "NPC-25 (100 mg / day) once-daily administration group vs Novergin (100 mg / day) twice-daily administration group" and were 1.9138 and 1.3620 respectively. That is, C on the first day of administration of the NPC-25 (100 mg / day) twice-daily administration group was higher compared to the Novergin (100 mg / day) twice-daily administration group, and C on the 14th day of administration trough was comparable to the Novergin (100 mg / day) twice-daily administration group. C on the first day of administration of the NPC-25 (100 mg / day) once-daily administration group was higher compared to the Novergin (100 mg / day) twice-daily administration group, and C on the 14th day of administration trough was comparable to the Novergin (100 mg / day) twice-daily administration group. C on the first day of administration of the NPC-25 (100 mg / day) once-daily administration group trough was higher compared to the Novergin (100 mg / day) twice-daily administration group, and C on the 14th day of administration was comparable to the Novergin (100 mg / day) trough twice-daily administration group.

[0097] t max The ratios of the average values on the first day of administration and on the 14th day of administration were "NPC-25 (100 mg / day) twice-daily administration group vs Novergin (100 mg / day) twice-daily administration group" and were 0.9583 and 1.2727 respectively, and "NPC-25 (100 mg / day) once-daily administration group vs Novergin (100 mg / day) twice-daily administration group" and were 1.0417 and 1​ was 0.2273. That is, the administration of NPC-25 (100 mg / day) twice a day at the first day and the 14th day of administration max was all at the same level as that of the novergine (100 mg / day) administered twice a day group. The administration of NPC-25 (100 mg / day) once a day at the first day and the 14th day of administration max was all at the same level as that of the novergine (100 mg / day) administered twice a day group.

[0098] From the above results, it can be seen that 100 mg / day per zinc of NPC-25 (histidine zinc), once a day administration also has an effect equivalent to or higher than that of 100 mg / day per zinc of novergine, administered twice a day.

[0099] Example 5: Open-label, uncontrolled, active-controlled trial for adult and pediatric patients with hypozincemia weighing 30 kg or more For adult and pediatric patients with hypozincemia weighing 30 kg or more, the efficacy and safety of NPC-25 tablets were examined by an open-label comparative trial with novergine tablets (manufactured by Novartis Pharma Co., Ltd.) as a control. Also, the dosage adjustment method until the target serum zinc concentration (80 μg / dL or more and less than 200 μg / dL) was reached by the administration of NPC-25 tablets and the maintenance effect after reaching were examined and confirmed.

[0100] The dosages and administration methods of the NPC-25 administration group and the novergine administration group were as follows.

[0101] NPC-25 Administration Group NPC-25 tablets were taken once a day after meals at the following dosages and usage. NPC-25 tablets: Histidine zinc hydrate was mixed with mannitol and a binder using a known method ​​​​Obtained by granulating together and tableting by a known method, a white tablet (NPC-25 tablet 25mg) containing 156.7 mg as a histidine zinc hydrate per tablet (25 mg as zinc). Initial dose: It was determined as follows according to the serum zinc concentration. · When the serum zinc concentration is 50 μg / dL or more and less than 70 μg / dL: Administered 50 mg / day as zinc (2 tablets once a day) for 4 weeks. · When the serum zinc concentration is less than 50 μg / dL: Administered 100 mg / day as zinc (4 tablets once a day) for 4 weeks. Subsequent dose adjustment: Until the serum zinc concentration reaches the target serum zinc concentration (80 μg / dL or more and less than 200 μg / dL), dose adjustment was performed according to the following criteria. <Increment criteria> Measure the serum zinc concentration every 4 weeks. If it is less than 80 μg / dL, · Increase by 50 mg / day as zinc and administer for 4 weeks. The maximum daily dose was 150 mg as zinc (6 tablets once a day). <Decrement criteria> · Measure the serum zinc concentration every 4 weeks. If it is 200 μg / dL or more, decrease by 25 mg / day as zinc and administer for 4 weeks. · When the serum copper concentration is 30 μg / dL or less, decrease by 25 mg / day as zinc. When it is less than 10 μg / dL, discontinue the administration. · When it is difficult to continue the administration of the dose determined due to the occurrence of adverse events, etc., decrease by 25 mg / day as zinc and administer for 4 weeks. <Administration termination criteria> · When the serum zinc concentration is maintained at 80 μg / dL or more and less than 200 μg / dL without changing the dose for 8 weeks (the blood zinc concentration 4 weeks and 8 weeks after reaching the target value is within the target value range )。However, it was stated that it can be administered up to a maximum of 52 weeks to patients who require continuous administration. · In cases where the serum zinc concentration was 200 μg / dL or more 4 weeks after administration even at 25 mg / day of zinc administration, the administration was discontinued.

[0102] Novergine Administration Group Novelgin tablets 25 mg were taken 1 to 3 times a day after meals according to the following dosage. Novelgin tablets 25 mg: White film-coated tablets containing 83.92 mg of zinc acetate hydrate (25 mg of zinc) in 1 tablet Initial dosage: It was as follows according to the serum zinc concentration. · When the serum zinc concentration was 50 μg / dL or more and less than 70 μg / dL: Zinc was administered at 50 mg / day (1 tablet once, 2 times a day) for 4 weeks. · When the serum zinc concentration was less than 50 μg / dL: 100 mg / day (2 tablets once, 2 times a day) was administered for 4 weeks. Subsequent dosage adjustment: Dosage adjustment was performed according to the following criteria until the serum zinc concentration reached the target serum zinc concentration (80 μg / dL or more and less than 200 μg / dL). <Increment criteria> The serum zinc concentration was measured every 4 weeks. If it was less than 80 μg / dL · The dosage was increased by 50 mg / day of zinc and administered for 4 weeks. The maximum daily dosage was 150 mg of zinc (2 tablets once, 3 times a day). <Decrement criteria> Same as the NPC-25 administration group. <Administration termination criteria> Same as the NPC-25 administration group. However, continuous administration was not approved, and the administration was up to a maximum of 24 weeks.

[0103] In this example, the serum zinc concentrations measured at the time of registration and within 8 weeks before the start of administration were at any time point A total of 216 adults and children aged 30 kg or more with serum zinc levels below 70 μg / dL were registered and randomly assigned to the NPC-25 treatment group or the nobelgin treatment group at a ratio of 1:1 (107 cases in the NPC-25 treatment group and 109 cases in the nobelgin treatment group). The subjects included in the efficacy analysis were those who were registered, excluding ineligible cases, cases with less than 20 days of investigational drug administration, and cases for which no information on efficacy was obtained after the start of investigational drug administration. The maximum analysis population (Full Analysis Set: FAS) was defined as such (103 cases in the NPC-25 treatment group and 107 cases in the nobelgin treatment group). The subjects included in the safety analysis were all cases for which any information on safety was obtained among the subjects who received the investigational drug, and this was defined as the safety analysis population (Safety Population: SP) (107 cases in the NPC-25 treatment group and 109 cases in the nobelgin treatment group). The treatment effect of hypozincemia was evaluated by measuring the changes in serum zinc concentration (analysis population: FAS), the changes in the proportion of subjects who reached the target serum zinc concentration (above 80 μg / dL and less than 200 μg / dL), the changes in the proportion of subjects who maintained the target serum zinc concentration (above 80 μg / dL and less than 200 μg / dL) at the same dose for 8 weeks, the period and dose from the start of administration until the first time the target serum zinc concentration (above 80 μg / dL and less than 200 μg / dL) was reached (analysis population: FAS), and the period and dose from the start of administration until the target serum zinc concentration (above 80 μg / dL and less than 200 μg / dL) could be maintained at the same dose for 8 weeks (analysis population: FAS).

[0104] Evaluation of the Therapeutic Effect on Hypozincemia

[0105] Changes in Serum Zinc Concentration (Analysis Population: FAS) ​​​​​​​​​​​​​​​Serum zinc concentration was measured every 4 weeks after the start of administration. Serum zinc concentration increased over time in both the NPC-25 administration group and the nobelgin administration group from 4 to 12 weeks. After 16 weeks, the NPC-25 administration group remained at the same level as at 12 weeks, but in the nobelgin administration group, serum zinc concentration decreased at 20 and 24 weeks after administration. The amount of change in serum zinc concentration at each observation time point according to the repeated measurement mixed effect model showed no significant difference between the NPC-25 administration group and the nobelgin administration group.

[0106] Proportion of Subjects Who Reached the Target Serum Zinc Concentration (80 μg / dL or More and Less than 200 μg / dL) Changes (Analysis Population: FAS) The proportion of subjects who reached the target serum zinc concentration increased in both administration groups after the start of the investigational drug administration. In both groups, by adjusting the dose, the target serum zinc concentration was rapidly reached, and by 24 weeks, 99.0% (102 / 103 cases) in the NPC-25 administration group and 95.3% (102 / 107 cases) in the nobelgin administration group achieved it. The achievement rate at each observation time point showed no significant difference between the NPC- 25 administration group and the nobelgin administration group.

The achievement rate at 12 weeks was 47.6% (49 / 103 cases) in the NPC-2 5 administration group and 36.4% (39 / 10 7 cases) in the nobelgin administration group. The achievement rate at 12 weeks in the NPC-25 administration group tended to be higher compared to the nobelgin administration group, and it was confirmed that the target serum zinc concentration could be maintained earlier in the NPC-25 administration group. A tendency was observed.

Specifically, it is as follows. Typical side effects of zinc preparations include digestive-related symptoms, and nausea and vomiting are factors that reduce the patient's medication compliance. The incidence of the side effect of nausea was 2.8% (3 / 107 cases) in the NPC-25 administration group and 6.4% (7 / 109 cases) in the Novergin administration group. Also, the incidence of vomiting was 2.8% (3 / 107 cases) in the NPC-25 administration group and 6.4% (7 / 109 cases) in the Novergin administration group. Also, the incidence of vomiting was 2.8% (3 / 107 cases) in the NPC-25 administration group and 6.4% (7 / 109 cases) in the Novergin administration group. Also, the incidence of vomiting The incidence rate of vomiting side effects was 0.9% (1 / 107 cases) in the NPC-25 administration group and 2.8% (3 / 109 cases) in the Novergin administration group. Thus, the incidence rates of typical side effects such as nausea and vomiting in the zinc preparation were all lower than those in the Novergin administration group.

[0116] Examples 6 and 7: Production of Test Samples 1 and 2 Histidine zinc hydrate, D-mannitol, and crystalline cellulose were combined by a stirring granulator, hydroxypropyl cellulose and purified water were added and granulated by stirring, and wet screening was performed using a screening machine.
