Conditions: Postmenopausal Osteoporosis
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 716
Healthy volunteers: no

Brief summary:
This 2 arm study will assess the impact of bone marker feedback (BMF), using serum carboxy-terminal collagen crosslinks (CTX) and communication of results at 3 months, on adherence to once monthly ibandronate (150 milligrams \[mg\] per oral \[po\]) in women with post-menopausal osteoporosis supported by patient-relationship program (PRP). Participants will be randomized either to receive BMF or no BMF; both groups will be supported by PRP. The anticipated time on study treatment is 3-12 months.

Detailed description:

Arms:
arm 1: Postmenopausal women will receive ibandronate 150 milligrams (mg) once monthly (QM) orally for 6 months. Participants, in this arm, will receive BMF at Month 3. BMF will be given in terms of providing serum carboxy-terminal collagen crosslinks (CTX) level at Month 3. A "BMF-form" will be provided to the physicians to allow offering the bone marker result in an easy way. Participants will be informed if their results are within or outside of the desired range. In addition, participants will also supported by PRP, to be carried out by supplying alarm devices, specifically designed to support the participant's regular drug intake. arm 2: Postmenopausal women will receive ibandronate 150 milligrams (mg) once monthly (QM) orally for 6 months. Participants will be supported by PRP, to be carried out by supplying alarm devices, specifically designed to support the participant's regular drug intake.

Interventions: intervention 1: Ibandronate
Intervention descriptions: intervention 1: Participants will receive ibandronate 150 mg QM orally for 6 months.
