Title:	Method of inhibiting or treating chemotherapy-induced hair loss
Abstract:	A method for inhibiting hair loss and/or promoting hair growth in chemotherapy and/or radiation therapy patients wherein the (R)-enantiomer of 4-[[(cyanoimino)-[(1,2,2-trimethylpropyl)amino]methyl]amino]benzonitrile is administered prior to, simultaneous with and/or after chemotherapy and/or radiation treatment.

Assignee:	Bristol-Myers Squibb Company (Princeton, NJ)
Application Number:	09/805,347
Patent Claims:	1. A method for promoting hair growth in a patient having chemotherapy-induced hair loss or radiation-induced hair loss, which comprises administering to a human or other mammal a therapeutically effective amount of the (R)-enantiomer of 4-[[(cyanoimino)[(1,2,2-trimethylpropyl)amino]methyl]amino]benzonitrile. 2. The method as defined in claim 1 wherein the (R)-enantiomer is administered prior to, or subsequent to chemotherapy or radiation therapy. 3. The method as defined in claim 1 wherein the (R)-enantiomer is administered prior to chemotherapy or radiation therapy. 4. The method as defined in claim 1 wherein the (R)-enantiomer is administered subsequent to chemotherapy or radiation therapy. 5. The method as defined in claim 1 wherein the (R)-enantiomer is administered topically. 6. The method as defined in claim 1 wherein the (R)-enantiomer is administered as a cream formulation, lotion formulation, liquid formulation or ointment formulation. 7. The method as defined in claim 1 wherein the (R)-enantiomer is administered systemically. 8. The method as defined in claim 1 for promoting hair growth in a patient having chemotherapy-induced hair loss. 9. The method as defined in claim 1 for promoting hair growth in a patient having radiation-induced hair loss. 10. The method according to claim 1 wherein the (R)-enantiomer is administered in conjunction with a chemotherapeutic agent. 11. The method according to claim 1 wherein the (R)-enantiomer is administered in conjunction with a chemotherapeutic agent which is an antineoplastic agent selected from the group consisting of an anthracycline drug, a vinca drug, a mitomycin, a bleomycin, a cytotoxic nucleoside, a taxane, an epothilone, discodermolide, a pteridine drug, a diynene, an aromatase inhibitor and a podophyllotoxin. 12. The method according to claim 1 wherein the (R)-enantiomer is administered in conjunction with a chemotherapeutic agent which is an antineoplastic agent selected from the group consisting of paclitaxel, docetaxel, 7-O-methylthiomethyl-paclitaxel, 3'-tert-butyl-3'-N-tert-butyloxycarbonyl-4-deacetyl-3'-dephenyl-3'-N-deben zoyl-4-O-methoxycarbonyl-paclitaxel, C-4 methyl carbonate paclitaxel, epothilone A, epothilone B, epothilone C, epothilone D, desoxyepothilone A, desoxyepothilone B, [1S-[1R*,3R*(E),7R*,10S*,11R*,12R*, 16S*]]-7,11-dihydroxy-8,8,10,12,16-pentamethyl-3-[1-methyl-2-(2-methyl-4-t hiazolyl)ethenyl]-4-aza-17-oxabicyclo[14.1.0]heptadecase-5,9-dione, [1S-[1R*,3R*(E),7R*,10S*,11R*,12R*,16S*]]-3-[2-[2-(aminomethyl)-4-thiazoly l]-1-methylethenyl]-7,11-dihydroxy-8,8,10,12,16-pentamethyl-4,17-dioxabicyc lo[14.1.0]heptadecane-5,9-dione, doxorubicin, carminomycin, daunorubicin, aminopterin, methotrexate, methopterin, dichloro-methotrexate, mitomycin C, porfiromycin, 5-fluorouracil, 6-mercaptopurine, gemcitabine, cytosine arabinoside, podophyllotoxin, etoposide, etoposide phosphate, teniposide, melphalan, vinblastine, vincristine, leurosidine, vindesine, leurosine, estramustine, cisplatin, carboplatin, cyclophosphamide, bleomycin, tamoxifen, ifosamide, hexamethyl melamine, thiotepa, cytarabin, idatrexate, trimetrexate, dacarbazine, L-asparaginase, camptothecin, CPT-11, topotecan, ara-C, bicalutamide, flutamide, leuprolide, a pyridobenzoindole, an interferon and an interleukin. 13. The method as defined in claim 1 wherein the (R)-enantiomer is administered in the form of a topical formulation comprising ethanol, propylene glycol and water. 14. The method as defined in claim 13 wherein the ethanol/propylene glycol/water are in a 60/30/10 proportion. 15. The method as defined in claim 1 wherein the (R)-enantiomer is administered in an amount from about 0.01 to about 15% by weight of said (R)-enantiomer. 16. The method as defined in claim 1 wherein the (R)-enantiomer is administered in the form of ethanol/propylene glycol/water, 60/30/10, is an amount to provide a 2% solution of the (R)-enantiomer. 17. The method as defined in claim 1 wherein the (R)-enantiomer is administered in combination with one or more other hair growth promoting agents. 18. The method as defined in claim 17 wherein said other hair growth promoting agent is another potassium channel opener, a 5-.alpha.-reductase inhibitor, an androgen blocker, betamethasone dipropionate, a corticosteroid, scopolamine and/or cyproterone acetate. 19. The method as defined in claim 18 wherein the other potassium channel opener is minoxidil, diazoxide, cromakalim and/or pinacidil; the 5-.alpha.-reductase inhibitor is finasteride, terazosin HCl, and/or doxaosin mesylate; the androgen blocker is 4-(5-methoxyheptyl)-hexahydro-2(1H)-pentalenone; and the corticosteroid is hydrocortisone. 20. The method as defined in claim 19 wherein said other hair growth promoting agent is a 5-.alpha.-reductase inhibitor. 21. The method as defined in claim 20 wherein the 5-.alpha.-reductase inhibitor is finasteride.
