メジャーの説明
時間枠
Percent Change From Baseline in Bone Mineral Density (BMD) at the Lumbar Spine to the End of Double-Blind Period
時間枠：From Baseline (Day 1) to the end of the Double-blind Period (Month 6)

Percent change from baseline in BMD at the lumbar spine was assessed by dual-energy x-ray absorptiometry (DXA) at 6 months. Missing postbaseline BMD other than due to COVID-19 were imputed using the last observation carried forward (LOCF) approach. Missing or out of window (exceed 70 days since previous IMP) post-baseline DXA BMD due to COVID-19 were set to missing and imputed by multiple imputation under missing at random approach. LSM = least square mean.
From Baseline (Day 1) to the end of the Double-blind Period (Month 6)
Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) During the Double-Blind Period
時間枠：From Baseline to the end of the Double-blind Period (Month 6)

An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a IMP, whether or not related to the IMP. TEAEs are defined as all AEs started on or worsened in severity on or after the date of receiving first dose of IMP and before or on the end of study (EOS) date.
From Baseline to the end of the Double-blind Period (Month 6)
Percentage of Participants With Treatment-emergent Adverse Events for Romosozumab During Overall Period
時間枠：From Month 7 up to Month 12 (Placebo/Romo) and From Day 1 up to Month 12 (Romo/Romo) + 3-month SFU (up to Month 15)

An AE is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with use of a IMP, whether or not related to IMP. TEAEs are defined as all AEs started on or worsened in severity on or after date of receiving first dose of IMP and before or on EOS date except lipid-type AEs starting on date of first dose of IMP and not worsening (and not deemed IMP related by the investigator). As pre-specified in Protocol and SAP, TEAEs were assessed and reported for 6 months for participants in placebo/romosozumab arm (Open-label Period) and for a total of 12 months for participants in romosozumab/romosozumab arm (Double-blind Period + Open-label Period combined) + 3 months of Safety follow-up for both arms (Up to Month 15) during overall period.
From Month 7 up to Month 12 (Placebo/Romo) and From Day 1 up to Month 12 (Romo/Romo) + 3-month SFU (up to Month 15)

IPD プランの説明

Data from this trial may be requested by qualified researchers six months after product approval in the US and/or Europe, or global development is discontinued, and 18 months after trial completion. Investigators may request access to anonymized individual patient-level data and redacted trial documents which may include: analysis-ready datasets, study protocol, annotated case report form, statistical analysis plan, dataset specifications, and clinical study report. Prior to use of the data, proposals need to be approved by an independent review panel at www.Vivli.org and a signed data sharing agreement will need to be executed. All documents are available in English only, for a prespecified time, typically 12 months, on a password protected portal. This plan may change if the risk of re-identifying trial participants is determined to be too high after the trial is completed; in this case and to protect participants, individual patient-level data would not be made available.
