Method for treatment or prevention of osteoporosis in individuals with high bone turnover
This invention relates to a method for the treatment or prevention of osteoporosis in an individual suffering from increased bone turnover, said method comprising administering to said individual an effective amount of a therapeutically active compound, which is a selective estrogen receptor modulator of the triphenylalkene or triphenylalkane structure.
1 . A method for the treatment or prevention of osteoporosis in an individual suffering from increased bone turnover, said method comprising administering to said individual an effective amount of a therapeutically active compound, which is a selective estrogen receptor modulator of triphenylalkene or triphenylalkane structure.
2 . The method according to claim 1 wherein the therapeutically active compound is a compound of the formula (I)
or a geometric isomer, a stereoisomer, a pharmaceutically acceptable salt, an ester thereof or a metabolite thereof.
3 . The method according to claim 2 wherein compound (I) is ospemifene.
4 . The method according to claim 1 , wherein the individual is a postmenopausal woman.
5 . The method according to claim 1 , wherein the increased bone turnover is a bone resorption and a bone formation being at least 5%, preferably at least 10% higher than the normal values for these markers.
6 . The method according to claim 1 wherein the individual has
a) a bone resorption of at least 65 nmol/mmol Creatine, using amino terminal telopeptide of type I collagen measured in urine (U-NTX) as marker, and/or at least 680 microgram/mmol Creatine, using carboxy terminal telopeptide of type I collagen measured in urine (U-CTX) as marker, and
b) a bone formation of at least 170 microgram/l, using carboxy terminal propeptide of type I procollagen measured in serum (S-PICP) as marker and/or at least 84 microgram/l, using amino terminal propeptide of type I procollagen measured in serum (S-PINP) as marker.
7 . The method according to claim 6 where the bone resorption, measured as U-NTX, is at least 70 nmol/mmol Creatine, and the bone formation, measured as S-PICP, is at least 180 microgram/l.
8 . The method according to claim 7 where the bone resorption, measured as U-NTX, is at least 80 nmol/mmol Creatine.
9 . The method according to claim 5 wherein the bone resorption has been measured wherein the bone resorption has been measured using as marker Crosslaps measured from serum.
10 . The method according to claim 5 wherein the bone resorption has been measured using as marker TRAP5b measured from serum.
11 . The method according to claim 5 wherein the bone resorption has been measured using as markers a combination of Crosslaps and TRAP5b, both measured from serum.
