NCT00377234

  Purpose

This 2-sequence crossover study will evaluate patient reported preference for once-monthly ibandronate (150 mg orally) as opposed to once-weekly risedronate (35 mg orally). Participants with post-menopausal osteoporosis will be randomized to receive one product for three months (12 weeks). They will then cross over to receive the other treatment for three months (12 weeks). The anticipated time on study treatment is 6 months (plus a 15-day follow up period), and the target sample size is 100-500 individuals.

Primary Outcome Measures:
  • Percentage of Participants Who Preferred Ibandronate Monthly Dosing to Risedronate Weekly Dosing [ Time Frame: at 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Percentage of Participants Who Found Once-monthly Ibandronate to be More Convenient Than Once-weekly Risedronate [ Time Frame: within 6 months ] [ Designated as safety issue: No ]
  • Intensity of Upper Gastrointestinal Symptoms [ Time Frame: within 3 months ] [ Designated as safety issue: No ]
  • Mean Change From Baseline in Bone Resorption and Bone Formation Markers, Serum C-telopeptide of α-chain of Type I Collagen (CTX) and Bone Specific Alkaline Phosphatase (BSAP) [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    During the conduct of this study, it came to the attention of the sponsor that mislabeling of blood samples for the analysis of the bone turnover markers, serum CTX and BSAP, had occurred at more than half of the 44 clinical trial sites. As a result of this mislabeling, the bone turnover marker samples could not be assigned correctly to the two time points at which they were collected (samples collected at baseline and those collected at the crossover visit which occurred after 3 months following the start of trial treatment). Thus, the results of bone turnover markers could not be reliably assessed. Therefore, summary tables showing the mean and median change from baseline for both serum CTX and BSAP for patients randomized to Sequence A (3 months of ibandronate followed by 12 weeks of risedronate) or Sequence B (12 weeks of risedronate followed by 3 months of ibandronate) are not presented, as a valid interpretation of the data cannot be made.
