Study Description
Brief Summary:

The primary objective of this pilot study is to estimate the percent change from baseline at Week 4, Month 6 in NTX bone turnover marker for a monthly 150mg dose of risedronate administered for 6 months and a loading dose regimen of risedronate over a 6 month treatment period both compared to a 5 mg daily dose of risedronate for 6 months

The secondary objectives are :

  • To estimate the percent change from baseline at specified visits other than Week 4, Month 6 in NTX for the monthly 150 mg dose of risedronate administered for 6 months and the loading dose regimen of risedronate over a 6 month treatment period both compared to the 5 mg daily dose of risedronate.
  • To estimate the percent change from baseline at all specified visits in serum CTX and bone specific alkaline phosphatase for the monthly 150 mg dose of risedronate administered for 6 months and the loading dose regimen of risedronate over a 6 month treatment period both compared to the 5 mg daily of risedronate.
  • To estimate the percent change from baseline at Month 6 in lumbar spine BMD for the monthly 150 mg dose of risedronate administered for 6 months and the loading dose regimen of risedronate over a 6 month treatment period both compared to the 5 mg daily dose of risedronate.
  • To evaluate the safety of the risedronate 150 mg monthly and the loading dose regimen.
