Definitions
- the present invention relates to a therapeutic or prophylactic agent for cachexia.
- Cachexia is a syndrome of complex metabolic disorders associated with underlying disease and is defined as being characterized by a decrease in muscle mass with or without a decrease in fat mass.
- Underlying diseases that cause cachexia include chronic diseases such as malignant tumors, tuberculosis, diabetes, blood diseases, endocrine diseases, infectious diseases, and acquired immunodeficiency syndrome, and marked weight loss, anemia, edema, and loss of appetite.
- Systemic weakness, malaise, etc. are known to be systemic syndromes (Non-Patent Document 1).
- cancer cachexia cachexia with malignant tumor as the underlying disease is called cancer cachexia and is said to account for about 20% of the causes of death of malignant tumors.
- Non-Patent Document 2 Non-Patent Document 2
- Patent Document 1 a ghrelin receptor agonist
- Patent Document 2 an androgen receptor modulator
- Ghrelin is a peptide hormone discovered as an endogenous ligand (GHSR agonist) of the growth hormone secretagogue receptor (GHSR). Ghrelin is mainly produced in the stomach in humans and animals via the ghrelin receptor and enhances growth hormone secretion (Non-Patent Document 3). In addition, it has been reported that ghrelin has various actions such as an eating disorder enhancing action (eating disorder improving action), a gastric acid secretion / gastric peristalsis promoting action, and a skeletal muscle mass increasing action (Non-Patent Document 3). .. Anamorelin, a ghrelin receptor agonist, showed a significant increase in lean body mass in a clinical phase 3 study, and is expected as a therapeutic agent for cachexia (Patent Document 3).
- Non-Patent Document 4 a Chinese herbal medicine, partially improves ghrelin resistance and has been shown to have therapeutic potential for cancer cachexia (Non-Patent Document 5).
- a compound having a morphinan skeleton or a pharmacologically acceptable acid addition salt thereof is disclosed to have opioid ⁇ receptor operability and its use as an analgesic and a diuretic (Patent Document 4). .. Further, the use as a cachexia therapeutic agent (Patent Document 5) is also disclosed.
- appetite stimulants such as ghrelin receptor agonists used for the treatment of cachexia do not show an improving effect on metabolic disorders, and the therapeutic effect is limited due to ghrelin resistance in patients, and steroids are used.
- Anti-inflammatory drugs are difficult to use for a long period of time due to their strong side effects.
- an object of the present invention is to provide a therapeutic agent or a preventive agent for cachexia, which has few side effects and exhibits remarkable efficacy in the treatment of cachexia.
- the present inventors use a specific compound having a morphinan skeleton or a pharmacologically acceptable acid addition salt thereof in combination with a ghrelin receptor agonist. As a result, they have found that they have an excellent therapeutic or preventive effect on cachexia, and have completed the present invention.
- the present invention is a therapeutic agent for cachexia, which comprises a combination of a compound represented by the following general formula (I) or a pharmacologically acceptable acid addition salt thereof and a ghrelin receptor agonist.
- a therapeutic agent for cachexia which comprises a combination of a compound represented by the following general formula (I) or a pharmacologically acceptable acid addition salt thereof and a ghrelin receptor agonist.
- the double line of the dotted line and the solid line indicates a double bond or a single bond
- R 1 indicates a cycloalkylalkyl having 4 to 7 carbon atoms
- R 2 is a linear chain having 1 to 5 carbon atoms. Alternatively, it indicates a branched alkyl
- the present invention also comprises, as one aspect of the above-mentioned therapeutic or preventive agent for cachexia, the compound represented by the above general formula (I) or a pharmacologically acceptable acid addition salt thereof, and a ghrelin receptor agonist. And, a therapeutic agent or a preventive agent for cachexia containing as an active ingredient.

- the amount of food intake was calculated by subtracting the weight of the lid of the cage containing the food of the previous day from the weight of the lid of the cage containing the food on the measurement day.
- 8 individuals in each group were bred in 2 cages of 4 animals each, and the total food intake for the 2 cages was divided by 8 to calculate the food intake per animal.
- FIGS. 5 and 6 The results are shown in FIGS. 5 and 6.
- the vertical axis of FIG. 5 shows the cumulative food intake during the administration period of various compounds (from the start of administration to the day following the final administration day).
- the vertical axis of FIG. 6 shows the body weight on the 12th day (the day after the final administration day) (after the administration for 11 days) after the start of administration of various compounds.
- "Distilled water” on the horizontal axis of FIGS. 5 and 6 indicates a distilled water administration group
- Compound 1 indicates a compound 1 administration group
- anamorelin indicates an anamorelin hydrochloride administration group
- “combined use” indicates a combined administration group of Compound 1 and anamorelin hydrochloride.
- the * mark in FIG. 5 indicates that it is statistically significant in comparison with the solvent-administered group (Dunnet multiplex test) (*: P ⁇ 0.05).
- the compound 1 and the anamorelin hydrochloride-administered group did not show a statistically significant effect of increasing the feeding amount as compared with the distilled water-administered group.
- the anamorelin hydrochloride combination-administered group showed a statistically significant effect of increasing the amount of food intake as compared with the distilled water-administered group.
- the body weight tends to increase as compared with the distilled water administration.
- the combined administration group of Compound 1 and anamorelin hydrochloride showed a tendency to gain weight.
- the therapeutic agent or preventive agent for cachexia of the present invention is useful in the pharmaceutical field because it has a high therapeutic effect on cachexia.
