Participant Flow

Subjects will be recruited from outpatient populations associated with health care centers that treat osteoporosis. Community advertising may also be used for those not associated with such centers. Recruitment began on 17 January 2011.

All patients had a two-week single-blind oral placebo (at bedtime) run-in period before group assignment. This was to accustom the patients to the oral dose regimen prior to randomization

Measure
Oral rsCT Tablets
Tablets containing 200 μg of recombinant salmon calcitonin, for oral administration. At group assignment the first 60 patients were told to self-administer the tablets once daily at bedtime (Group 1). The remaining patients were told to self-administer once daily at dinner time (Group 2)to determine if there was any food effect. Randomization was done active:placebo, 2:1.
Oral Placebo Tablets
Identical appearing placebo tablets, without active ingredient At group assignment the first 60 patients were told to self-administer the tablets once daily at bedtime Group 1). The remaining patients enrolled were told to self-administer once daily at dinner time (Group 2)to determine if there was any food effect. Randomization was done active:placebo, 2:1.
