Definitions
- the present invention relates to a therapeutic agent for uterine fibroids, which has few side effects such as a decrease in bone density, can be used alone or in combination with a GnRH agonist, and can be administered for a long time.
- Dienogest is an international generic name (INN) of a known compound having a structure represented by the following formula (I) (17 «-cyanomethyl-17 ⁇ -hydroxy-estra_4, 9 (10) -dien-3-one). is there.
- Dienogest is known to have luteinizing hormone activity, and a combination drug with ethinylestradiol is manufactured in Germany and sold as an oral contraceptive. Dienogest is also under clinical development as a therapeutic agent for endometriosis (Kohler et al., Archives Gynecol. Obstet. ), Vol. 255, pp. 594-5995, 1993), and its efficacy against endometrial cancer and breast cancer has been experimentally reported (Koki et al., Japanese Patent Application Laid-Open No. — 188026; Koki et al., Cancer, Vol. 79, pp. 169-176, 199). The effects of dienogest on fibroids have not been reported.
- Fibroids are said to be present in 20 to 40% of women aged 30 and older, and are one of the most frequent diseases in obstetrics and gynecology.
- Uterine fibroids differ from endometriosis and endometrial cancer in that they are benign tumors composed of smooth muscle, and uterine fibroids develop mainly in the sexual maturation phase and develop after menopause or castration. Cessation or shrinkage of the mass is observed.
- GnRH gonadotropin-releasing hormone
- GnRH agonists have a therapeutic effect on uterine fibroids, but also have side effects such as bone mineral loss and menopausal symptoms based on their main effect, estrogen lowering effect in blood. Highly expressed. Due to these risks, the period of taking GnRH agonist is usually restricted to about 6 months. It is also known that uterine fibroids return to their pre-treatment size when the GnRH agonist is discontinued (Freidman et al., Fertility 'and Sterility 1). .), Vol. 49, pp. 404-409, 1988).
- luteinizing hormone has recently been shown to act as a growth-promoting factor for uterine fibroids (Rein et al., Supra; Fujii et al., Supra), and may have an adverse effect on the treatment of uterine fibroids. ing. Under these circumstances, the application of dienogest to uterine fibroids has not been excluded. Disclosure of the invention
- GnRH agonists are currently widely used in pharmacotherapy for uterine fibroids, but the frequency of side effects such as bone resorption and climacteric symptoms is high, and the duration of administration is limited. In addition, the recoil phenomenon after taking the drug is also an important issue. Therefore, development of a therapeutic agent free of these side effects and problems is desired. Also, when used as a concomitant drug with GnRH agonist, It is also desirable to develop a drug that does not eliminate the action of gonisters to reduce fibroids, or a new drug that prevents GnRH agonists from regrowing once reduced fibroids and that reduces GnRH agonists' side effects as much as possible. It is. The present invention solves at least one of these problems.
- dienogests were capable of meeting these requirements.
- dienogest has the effect of reducing human uterine fibroid tissue, and, unlike GnRH agonists, has no effect on bone mineral density at all, and has a recoil phenomenon after taking medication. was significantly suppressed.
- the dienogest which is an active ingredient of the therapeutic agent for uterine fibroids of the present invention, is a compound having the structure of the formula (I), as described above, and various pharmaceutically acceptable solvents such as water, ethanol, glycerol, and acetic acid. To form solvates.
- a first aspect of the present invention is a therapeutic agent for uterine fibroids, comprising dienogest or a solvate thereof as an active ingredient. Further, the present invention is a therapeutic agent for uterine fibroids, which comprises, as an active ingredient, dienogest or a solvate thereof in which the recoil phenomenon after drug discontinuation is suppressed.
- a second aspect of the present invention is the therapeutic agent for uterine fibroids for use in combination with another therapeutic agent for uterine fibroids.
- the other therapeutic agent for uterine fibroids used in combination is a GnRH agonist, a GnRH antagonist, an aromatase inhibitor, or an antiestrogen.
- a third aspect of the present invention is the therapeutic agent for uterine fibroids, which is intended to be administered during a drug holiday of a GnRH agonist and a GnRH antagonist.
- the present invention also provides a method for treating uterine fibroids using dienogest or a solvate thereof, and a method for producing a therapeutic agent for uterine fibroids, comprising dienogest or a solvate thereof as an active ingredient. Also provided is the use of dienogest or a solvate thereof for the manufacture of a pharmaceutical composition for the prevention or treatment of uterine fibroids.
- the above-mentioned therapeutic agent of the present invention can be used for prevention of uterine fibroids and prevention of recurrence.
- FIG. 1 shows a comprehensive statistical analysis of the effect of the test drug on human uterine fibroid tissue with respect to grafts of 14 donor samples.
- buserelin acetate is a representative GnRH agonist and has indications for uterine fibroids.
- MPA is the most typical luteinizing hormone preparation and can be administered orally similarly to dienogest.
- Uterine fibroid tissue obtained by performing a total hysterectomy from a uterine fibroid patient was used. According to Aoki et al.'S method (Obstet. Gynecol., Vol. 83, pp. 220-228, 1991), the fibroid tissue was transformed into a square thigh.
- the CB—17 skid female mice weighing 17 to 21 g were subcutaneously transplanted one by one into the back. Three weeks after the transplantation, it was confirmed that the graft had survived, and the animals were divided into groups of two per group. The first group was administered with a solvent (0.5% carboxymethylcellulose solution, hereinafter abbreviated as CMC) to serve as a control group. Dienogest and MPA were dissolved or suspended in CMC and administered orally, and buserelin acetate was administered subcutaneously for 6 weeks every day.
- CMC carboxymethylcellulose solution
- the volume of the uterine fibroid graft was measured using an ultrasonic diagnostic device (type SSD-650, Aloka, Tokyo) according to the method of Aoki et al.
- the rate (%) was calculated from the following formula (A).
- Uterine fibroid tissue obtained by performing total hysterectomy from four patients with uterine fibroids (donors) was used.
- the animals were divided into groups. The first group received a CMC solvent to serve as a control group. Dienogest was suspended in CMC and administered orally, and buserelin acetate was administered subcutaneously for 6 consecutive days (treatment period). In each group, observation was continued for 4 weeks after the end of drug administration (follow-up period). During the experimental period, the volume of the graft was measured once a week in accordance with Experimental Example 1.
- the volume of the graft before administration of the drug in each animal was set at 100%, and the ratio to this was calculated.
- the average of the values obtained from two animals of the same donor and one group was expressed as the result of one case.
- the rate of change of each graft size was measured weekly over the entire experimental period, and comprehensive analysis was performed on the grafts of the four donors.
- the results of the analysis are shown in Fig. 1 as changes in graft volume change rate during the treatment period and the follow-up period.
- Table 2 summarizes the graft volume change rate before and after the follow-up period for each donor. Table 2 Effect of test drug on human uterine fibroid tissue (treatment period vs. follow-up period) Drug / dose Myoma tumor volume change rate (%)
- the effective dose of dienogest to uterine fibroid tissue shown in this experimental example was used as an oral contraceptive in Germany.
- the dose is almost equivalent to the clinical dose of the drug (2 mg daily), and its safety has been confirmed in clinical trials (daily dose l to 4 mg) as a single agent for the treatment of endometriosis. Therefore, it seems that there is no problem.
- MPA acts as a growth factor for uterine fibroids and is unsuitable as a therapeutic agent
- dienogest is clearly different from conventional luteinizing hormone drugs and significantly reduces transplanted uterine fibroids. Clarified that it can be used as a therapeutic agent.
- its efficacy is considered to exceed the effect of the existing therapeutic agent for uterine fibroids (GnRH agonist), and can be used as a new therapeutic agent for uterine fibroids.
- dienogest Unlike GnRH agonists, dienogest usually has no effect on bone mineral density (Sasakawa et al., Japanese 'Journal' Job ', Pharmacol. Jpn. J. Pharmacol. Volume 7 (suppl.), 162p, 1995), can be a therapeutic agent for uterine fibroids with fewer side effects.
- the recoil after discontinuation of medication which has been a problem with existing uterine fibroid treatments, has been demonstrated. It is expected to be a therapeutic agent with excellent characteristics that will be improved.
- the therapeutic agent for uterine fibroids of the present invention is used in various aspects of hormone therapy. In other words, it may be administered alone for uterine fibroids or in combination with existing hormonal therapies provided for the treatment of uterine fibroids.
- the combination may be simply administered to the patient at the same time as the GnRH agonist, add-back therapy, or using the GnRH agonist during the drug holiday.
- add-back therapy the period of GnRH agonist administration alone and the period of simultaneous administration with the present therapeutic agent are combined, and the length and dose of each period are adjusted according to the patient's condition.
- a reference by Freedman et al. Fertil. Sterility (Fertil. Steril.), Vol. 49, pp. 404-409, 1 988

- Vol. 49, pp. 404-409, 1 988 can be used with reference to the MPA administration method disclosed in
- dienogest can be used alone.
- estrogen may be used in combination.
- dienogest also has an action of antagonizing the bone mineral density reducing action of GnRH agonist, and when used together with GnRH agonist, enhances its main effect, but reduces side effects, and is also preferable as a concomitant drug.
- the therapeutic agent for uterine fibroids of the present invention can be administered alone or in combination with other drugs.
- Specific examples of the form of administration include tablets, capsules, tablets coated with sugar or skin, granules, fine granules, powders, liquid solutions or suspensions, emulsions, and fat emulsions. , Ointments, etc., used orally or parenterally, as suppositories It can be administered rectally or vaginally, subcutaneously, intramuscularly or intravenously as an injection.
- a sustained-release preparation such as a patch, a tape, or an intradermal implant can be prepared.
- the dosage is about 0.5 to 1 mg / day, preferably 1 to 5 mg / day, 1 to 5 times a day for adults, depending on the patient's age, weight, health condition and route of administration.
- the dose and the number of doses can be adjusted.
- GnRH antagonists include cetrorelix, ganirelix, lamorelix, and untide.
- the GnRH antagonist is a therapeutic agent for uterine fibroids that exerts an estrogen inhibitory effect by directly blocking the GnRH receptor.
- Other hormones include danazol and antiestrogens such as tamoxifen and clomiphene. Examples of aromatase inhibitors include fadrozole and vorozole.
- Magnesium stearate 5.0 g The above ingredients are mixed, and 10 Omg each is encapsulated in a Japanese Pharmacopoeia No. 3 capsule to form a capsule.
- the above components are appropriately mixed and formed into 150 mg tablets containing 0.40 mg of dienogest per tablet by a wet granulation compression method.
- the above ingredients are melt-kneaded as appropriate and sealed in a package to make a suppository weighing 1.0 g per piece.
- the therapeutic agent for uterine fibroids of the present invention can exert a therapeutic effect equal to or higher than that of a conventional hormonal therapeutic agent. For example, it can be expected to have a therapeutic effect on patients who could not be completely cured by conventional GnRH agonists. Furthermore, the therapeutic agent for uterine fibroids of the present invention is safer than conventional drugs, and can be administered for a long period of time, since the side effects that have been regarded as problems with conventional hormonal therapies (particularly GnRH agonists) do not pose any problem. can do. Specifically, there is no bone resorption or climacteric symptoms, and it is possible to continue treatment alone for at least 6 months. It can be taken for a long time until menopause to reduce fibroids.
- it is expected as a drug that does not cause recoil during the drug holiday.
- a GnRH agonist when used in combination with a GnRH agonist, it can be used as a drug that does not cause side effects such as bone resorption without reducing its main effect.
- it can be administered as a highly safe drug during the drug holiday such as a GnRH agonist.
