Association between renal function and fracture incidence during treatment with teriparatide or alendronate: an exploratory subgroup analysis of the Japanese Osteoporosis Intervention Trial-05.

Unlabelled: The association of renal function with fracture incidence during teriparatide or alendronate treatment in elderly Japanese women was examined. Fracture incidence differed by fracture type, renal function, and treatment protocol. The results provide important information on pharmacotherapy in clinical practice for osteoporosis.

Predictors of discontinuation of osteoporosis treatment: sub-analysis of the Japanese osteoporosis intervention trial-05 (JOINT-05).

Introduction: To identify predictors of discontinuing treatment with teriparatide (TPTD) and alendronate (ALN), data from a randomized, controlled trial (JOINT-05) involving postmenopausal Japanese women at high risk of fracture were re-analyzed.

Materials And Methods: Participants received sequential therapy with once-weekly TPTD for 72 weeks followed by ALN for 48 weeks (TPTD-ALN group) or monotherapy with ALN for 120 weeks (ALN group). Background data including comorbidities, fracture prevalence, cognitive function, quality of life, activities of daily living, bone metabolism parameters, and nutrient intake were collected.

Drug utilization pattern of romosozumab and other osteoporosis treatments in Japan, 2019-2021.

Introduction: Describe real-world treatment of osteoporosis and romosozumab treatment patterns in Japan.

Materials And Methods: Data for patients initiating romosozumab or other antiosteoporotic medications between March 01, 2018, and May 31, 2022, were extracted from the Medical Data Vision (MDV) and Japan Medical Data Center (JMDC) databases. Patients were categorized into four cohorts: those who newly initiated romosozumab within the first (MDV: n = 4782; JMDC: n = 2578) or second (MDV: n = 3888; JMDC: n = 2446) year after launch and those who initiated teriparatide (TPTD; MDV: n = 14,576; JMDC: n = 8259) or non-TPTD antiosteoporotic medications within the first year of romosozumab launch (MDV: n = 352,142; JMDC: n = 185,785).

A crossover comparison of patient satisfaction with two teriparatide regimens: primary results of the Japanese Osteoporosis Intervention Trial 06 (JOINT-06).

Introduction: This study aimed to compare treatment satisfaction with two dosing regimens (two teriparatide [TPTD] self-injection systems) in osteoporosis patients at high risk of fracture.

Materials And Methods: In this open-label crossover randomized trial comparing self-injected once-daily (1/D)-TPTD with self-injected twice-weekly (2/W)-TPTD, three satisfaction variables were evaluated by questionnaire for 2 years. The primary endpoint was overall satisfaction and secondary endpoints were satisfaction with treatment effectiveness and with utility of the self-injection device.

Achieving osteoporosis treat-to-target goals with teriparatide or alendronate: sub-analysis of Japanese Osteoporosis Intervention Trial-05 (JOINT-05).

Introduction: The purpose of this study was to evaluate whether bone mineral density (BMD) ≥ -2.5 SD could be used as the treat-to-target (T2T) goal when treating osteoporosis with teriparatide (TPTD) and alendronate (ALN), and to investigate the relationship with incident vertebral fracture by re-analyzing data from a randomized, controlled trial (JOINT-05) involving postmenopausal Japanese women at high fracture risk.

Materials And Methods: Participants received sequential therapy with once-weekly TPTD for 72 weeks, followed by ALN for 48 weeks (TPTD-ALN group) or ALN monotherapy for 120 weeks (ALN group).
