Further study details as provided by Procter and Gamble:

Primary Outcome Measures:

Evaluate the safety of 3 once-monthly dosing regimens of risedronate, 100 mg, 150 mg and 200 mg, compared to a once-daily dosing regimen, 5 mg, as assessed by clinical laboratory values and adverse event (AE) profiles [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

Evaluate the efficacy of 3 once-monthly dosing regimens or risedronate compared to a once-daily dosing regimen and to evaluate the PK/PD of monthly and daily dose regimens [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
