A Study of Adherence to Once Monthly Ibandronate (Bonviva) in Women With Post-Menopausal Osteoporosis, Supported by a Patient Relationship Program (PRP)

31 de agosto de 2016 actualizado por: Hoffmann-La Roche

A Randomized Open-Label Study to Investigate the Impact of Bone Marker Feedback at 3 Months on Adherence to Monthly Oral Bonviva in Women With Post-Menopausal Osteoporosis Supported by a Patient Relationship Program

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.

Experimental: Bone Marker Feedback (BMF) Participants
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.
Participants will receive ibandronate 150 mg QM orally for 6 months.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Percentage of Participants With Adherence to Treatment
Periodo de tiempo: Up to 6 months
Participants were considered adherent to treatment if they took at least 83 percent (%) of their assigned medications (5 of the 6 monthly ibandronate tablets) within the -1 to +21 days of their osteoporosis treatment date each month. Participant adherence was assessed by maintaining records of 'drug dispensed' and 'drug returned' on case report form (CRF) and participant's self-report on Visit 2 (Month 3) and final study visit (Month 6). A drug dispensing log was maintained by the investigator. Participants were instructed at the baseline visit and Visit 2 to save and return unused or partially used medication packages on Visit 2 and final study visit, respectively.
Up to 6 months

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Percentage of Participants With Osteoporosis Patient Satisfaction Questionnaire (OPSAT-Q) Composite Satisfaction High Scores
Periodo de tiempo: At Month 6
The OPSAT-Q is a validated questionnaire designed to capture satisfaction with bisphosphonate treatment. It comprises four domains: convenience (questions 1 - 6), quality of life (questions 7 and 8), overall satisfaction (questions 9 and 10), and side effects (questions 11 - 16). Satisfaction with treatment was assessed using the OPSAT-Q composite satisfaction score, which was the average of the scores from the four domains of the OPSAT-Q converted to a 0 - 100-point scale. Higher scores indicated greater treatment satisfaction. A score of 80 or more was considered as high score.
At Month 6
Percentage of Participants With Osteoporosis Patient Perception Survey (OPPS) and Osteoporosis Medical Care Satisfaction Questionnaire (OMSQ) Composite Satisfaction High Score
Periodo de tiempo: At Month 6
OPPS: A standardized 6-item satisfaction questionnaire for osteoporosis medical care and treatment received during the study. Individual item score was transformed and converted to a 0 to 100 scale where higher score indicated greater satisfaction. The composite score was the average of individual item scores (transformed) and ranged from 0 to 100, where higher scores indicated greater satisfaction. OMSQ: A standardized 18-item satisfaction questionnaire for osteoporosis medical care, treatment received and blood test and their results during the study. Individual item score was transformed and converted to a 0 to 100 scale where higher score indicated greater satisfaction. The composite score was the average of individual item scores (transformed) and ranged from 0 to 100, where higher scores indicated greater satisfaction.
At Month 6
Percent Change From Baseline in CTX Based on Adherence to Ibandronate
Periodo de tiempo: Baseline, Month 6
Serum CTX, a biochemical marker of bone resorption, was assessed for all participants at baseline and at final visit (Month 6). The sampling was done at the same time of the day each time to overcome the effect of circadian fluctuations. Participants were considered adherent to treatment if they took at least 83% of their assigned medications (5 of the 6 monthly ibandronate tablets) within the -1 to +21 days of their osteoporosis treatment date each month. Participant adherence was assessed by maintaining records of 'drug dispensed' and 'drug returned' on CRF and participant's self-report on Visit 2 (Month 3) and final study visit (Month 6). A drug dispensing log was maintained by the investigator. Participants were instructed at the baseline visit and Visit 2 to save and return unused or partially used medication packages on Visit 2 and final study visit, respectively.
