Postmenopausal Osteoporosis
Conditions
Brief summary
The purpose of the event-driven base study is to determine the safety and efficacy, especially fracture risk reduction, of odanacatib in postmenopausal women diagnosed with osteoporosis. In a placebo-controlled extension of the base study, participants continued to receive the same blinded study medication for a total of up to 5 years of blinded study medication combined between the base study and the extension. After participants received 5 years of blinded study medication, they received open-label odanacatib through the end of the first extension. Participants were then invited to enroll in a second extension study in which they received open-label odanacatib for an additional 5 years. Two imaging substudies (PN032-Base/Extension and PN035) were conducted for participants in the MK-0822-018 Study. Additional safety information was collected for participants who discontinued from the base study or the blinded first extension in an observational follow-up study, MK-0822-083 (EudraCT number: 2007-002693-66) .

Participants are asked to walk a distance of 4 meters at their normal pace. The test is performed 2 times, and the walk done in the shortest time is used for scoring. The activity is timed and then reduced to a categorical 0 to 4 scale based on time achieved. Higher scores indicate an improved function level. The change from baseline at yearly intervals was then assessed using a longitudinal data analysis model with terms for treatment, stratum (sarcopenia, non-sarcopenia), time and interaction between treatment and time as fixed effects (LS means weighted for stratum size). |
| Sarcopenia Substudy PN035: Change From Baseline in Short Physical Performance Battery (SPPB) Score | Baseline and once yearly up to 4 years | The Short Physical Performance Battery (SPPB) Score is used to assess physical function in older persons.

Base Study + First Extension + Second Extension: Percent Change From Baseline in Bone Mineral Density (BMD) Measurements of the Total Hip
BMD was measured by dual-energy x-ray absorptiometry (DXA) at the total hip starting at screening, and at yearly intervals until the end of the study (second extension study) for all participants who entered the second extension study. Least squares (LS) means percent change in BMD from original baseline are provided through Month 108 (Year 9). At Months 96 (Year 8) and 108 (Year 9), approximately 3% or fewer participants in each treatment group had BMD data, and results at those time points should be viewed with caution. NOTE: The mean percent change in BMD from baseline in participants originally randomized to placebo includes BMD results obtained after those participants were switched to open-label odanacatib, which occurred at different times relative to their start of blinded study medication in the base study.
Time frame: Baseline and once yearly, up to approximately 108 months of observation
Population: The FAS population including all randomized participants who took at least one dose of study medication and having the necessary on-treatment information (total hip BMD) was used for analysis (base study + first extension-dbp + second extension).

Base Study + First Extension + Second Extension: Time From Baseline to First Morphometrically-Assessed Vertebral Fracture
Morphometric vertebral fractures were assessed by central adjudication on lumbar and thoracic spinal radiographs acquired at baseline (base study) and at Months 6, 12, and subsequent yearly time points. Incident fractures (i.e., occurring after baseline) in previously normal vertebral bodies and/or those occurring after baseline in previously fractured vertebral bodies (Genant semiquantitative \[SQ\] Grade 1-3) (T4 to L4) were confirmed by quantitative morphometric (QM) and either SQ or binary SQ (yes/no) methodologies. A time-to-event methodology was used to evaluate results: life-table estimates of the incidence proportion (cumulative incidence) of participants with at least one morphometric vertebral fracture were assessed at Months 6, 12, and subsequent yearly intervals; an interval-censored approach was then used to determine incidence rate (number of participants with a morphometric fracture per 100 person-years of follow-up).
Time frame: Up to approximately 108 months of observation
Population: Study was terminated early due to observed increase in risk of stroke in Protocol MK-0822-018. As a result, efficacy analyses in 2nd Extension were limited to change in BMD and incidence of osteoporotic clinical fractures; Base Study + 1st Ext + 2nd Ext: Time From Baseline to First Morphometrically-Assessed Vertebral Fracture was not analyzed.
Base Study + First Extension: Time From Baseline to First Osteoporotic Clinical Fracture (Adjudicated)
Osteoporotic clinical fractures (combining vertebral and non-vertebral) were confirmed by central adjudication using radiographic evidence on all symptomatic fractures reported as adverse experiences (excluding fractures of the fingers, toes, face, and skull). Vertebral fractures were assessed for all vertebral levels (C7, T1 to T12, L1 to L5). Non-vertebral fractures were assessed across multiple anatomical sites including clavicle, distal femur or shaft, fibula, hip, humerus, pelvis, radius, ribs, sacrum, tibia, ulna, and wrist. Osteoporotic (fragility) fractures did not include fractures with traumatic or pathological etiologies. A clinical fracture was defined as a fracture with clinical fracture-related symptoms (e.g., pain). A time-to-event methodology was used to evaluate results: the incidence rate of participants with fracture (number of participants with a fracture per 100 person-years of follow-up) is provided.
Time frame: Up to approximately 74 months of observation
