Description

NOVEL TREATMENT This invention relates to the use of certain Vitamin D analogues in the preparation of a pharmaceutical preparation for the treatment and/or prevention of alopecia.
Alopecia (a partial or complete loss of hair) is due to a deficiency of terminal hair which is the visual coloured hair. If the hair loss is due to atrophy or scarring, no regrowth can be expected. But in other cases, even where there is a noticable absence of terminal hair, the skin of a seemingly bald person may contain the socalled vellus hair which is a very fine colourless hair, the presence of which needs microscopic determination. The vellus hair is a precursor to the terminal hair, and a regrowth may thus be promoted both by influencing the conversion of vellus hair to terminal hair and by stimulating the growth of the latter.
Alopecia may result from genetic factors, from ageing, from local or systemic diseases and as a side effect in connection with cancer chemotherapy. Male-pattern baldness is extremely common, it is familial and requires the presence of androgens, but other etiological factors are unknown. Female-pattern alopecia is not infrequent in women.
It is ordinarily confined to thinning of hair in the frontal and the parietal regions.
It is further known that many patients suffering from the hereditary disorder 'vitamin D-dependent ricketts type II' have alopecia.
This is a puzzling association between hereditary vitamin D resistance and alopecia since alopecia is not generally associated with other vitamin D deficiency states, and it suggests that la,25-dihydroxyvitamin D3 (1,25-(OH)2D3, the active form of vitamin D3) has a physiological role outside its classic targets tissues and may be required to promote differentiation of the hair follicle during the development, see also Arase, S. et al, J. Derm.
Sci. X, 353-360 (1991).
As alopecia is mainly a cosmetic problem, any therapy should never present risks which are unjustifiable. Topical application of the natural form of active vitamin D, i.e.
1,25-(OH)2D3, represents one possibility for such treatment, but because of its potent calcemic activity there will be a risk that, through transdermal absorption, it will give rise to undesired systemic effects leading to hypercalcemia.
However, by choosing a vitamin D analogue which has only moderate activity on calcium metabolism compared to 1,25-(OH)2D3, but having retained the ability to activate receptors for 1,25(OH)2D3 not associated with calcium absorption or bone calcium mobilization it is possible to treat and/or prevent alopecia successfully without having the risk of inducing hypercalcemia.
Examples of such vitamin D analogues for use in the present pharmaceutical preparations are 1) compounds described in international patent application No. PCT/DK86/00081, international filing date 14th July, 1986, International Publication No.
WO 87/00834, in particular the compound designated MC 903 (example 5 in said patent application) (confer also Calverley, M., Tetrahedron 43, 4609-4619 (1987); Binderup, L. and Bramm, E., Biochemical Pharmacology 37, 889-895 (1988)), 2) compounds described in international patent application No. PCT/DK89/00079, international filing date 7th April, 1989, in particular Compound 35 (Ex ample 2), Compound 37 (Example 4), Compound 38 (Example 5), Compound 54 (Example 9), Compound 55 (Example 10), and Compound 59 - LEO Code CB 966 (Example 12) 3) 24-homo- and 26-homo-la,25-dihydroxyvitamin D3 (together with their 22,23-didehydro-analogues) (Ostrem, V.K. et al, Proc. Natl. Acad. Sci.USA 84, 2610-2614 (1987)), 4) 20-oxa-21-nor-la,25-dihydroxyvitamin D3 and 22-oxa-la,25-dihydroxyvitamin D3 (Abe, J. et al, FEBS Letters 2k, 58-62 (1987)), and 5) 26,27-dimethyl- and 26,27-diethyl-la,25-di hydroxyvitamin D3, and 24, 24-difluoro-24-homo-la, 25 dihydroxyvitamin D3 (Ikekawa, N. et al, Chem. Pharm.
Bull. 35, 4362-65 (1987)), The mentioned compounds shall form part of pharmaceutical preparations, in particular for topical use, which are useful in the treatment of human disorders as described above, such as a liniment, a lotion, a cream or a gel which in addition to the vitamin D analogues in question may contain further active ingredients, such as a socalled potassium channel opener like minoxidil, cromokalim or pinacidil. The concentration of the active ingredients will depend upon the choice of vitamin D analogues but will generally be between 1 and 100 pg/g.
The formulations will be applied once or twice daily for prolonged periods of time.
The formulations prepared according to the present invention comprise an active compound in association with a pharmaceutically acceptable vehicle therefore and optionally other therapeutic ingredient(s). The vehicle(s) must be "acceptable" in the sense of being compatible with the other ingredients of the preparations and not deleterious to the recipient thereof.
Preparations suitable for topical administration include liquid or semi-liquid preparations such as liniments, lotions, applicants, oil-in-water or water-in-oil emulsions such as creams, ointments, pastes or gels; or solutions or suspensions.
In addition to the aforementioned ingredients, the preparations of this invention may include one or more additional ingredients such as diluents, buffers, flavouring agents, binders, surface active agents, thickeners, lubricants, preservatives, e.g. methyl hydroxybenzoate (including anti-oxidants), emulsifying agents and the like.
The preparations may, as mentioned above, contain further therapeutically active compounds usually applied in the above mentioned treatment.
In the topical treatment, ointments, creams, gels, or lotions containing from 1-100 sug/g of the vitamin D analogues or metabolites are administered.
The present invention further concerns a method for treating patients suffering from or in risk of getting alopecia, said method consisting of administering topically to a patient in need of treatment an effective amount of one or more of the above mentioned vitamin D analogues or metabolites, alone or in combination with one or more other therapeutically active compounds usually applied in such treatment. The treatment with the present compounds concomitantly with further therapeutically active compounds may be simultaneous or with intervals.
The invention will now be further described in the following non-limiting Examples: Example 1 Cream Containing MC 903 In 1 g almond oil was dissolved 1 mg MC 903. To this solution was added 40 g of mineral oil and 20 g of self -emulsifying beeswax. The mixture was heated to liquify.
After the addition of 40 ml hot water, the mixture was mixed well. The resulting cream contains approximately 10 pg of MC 903 per gram of cream.
Example 2 Cream containing 22-oxa-la,25-dihydroxy- vitamin D3 By using the procedure described in Example 1, but replacing MC 903 with 22-oxa-la,25-dihydroxyvitamin D3, the desired cream was obtained.

Example 6 Prevention of cytoxan-induced alopecia by MC 903 Three groups of each 10 5-day-old Sprague-Dawley rats were treated topically over the head and neck with daily doses of A. 0.15 ml of absolute ethanol B. 0.2 pg of 1,25(OH)2D3 (calcitriol) dissolved in 0.15 ml of absolute ethanol C. 0.2 pg of MC 903 dissolved in 0.15 ml of absolute ethanol for 5 days.
One day after the last topical treatment all rats were treated with cytoxan 35 ml/kg given intraperitoneally.
All animals in group A became totally alopecic whereas all animals in groups B and C were protected.
Whereas the mean serum level of Ca in group B was markedly increased compared to the control rats (group A) no such increase could be detected in the animals in group C.
Example 7 Prevention of alopecia induced by a combi nation of Adriamycin and cytoxan by the vitamin D-analogue KH 10601 Three groups of each 10 5-day-old Sprague Dawley rats were treated over the head and neck with daily doses of A. 150 pl of propylene glycol B. 0.2 lug of 1,25(OH)2D3 (calcitriol) in 150 pl of propylene glycol C. 0.02 pg of KH 1060 dissolved in 150 pl of propylene glycol At the 11th day of age all animals were treated intraperitoneally with cytoxan 25 mg/kg and adriamycin 2.5 ml/kg. The same adriamycin dose was repeated on the 12th day and 13th day of age.
All 10 rats in the control group (group A) developed alopecia over the head and neck. In contrast all animals in groups B and C were protected - primarily at the side of the drug application.
The animals in group B had a significantly higher serum level of Ca than the animals in group A, whereas the serum level of Ca in group C was similar to that in group A.
