Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Maximum Observed Serum Concentration (Cmax) of Romosozumab | Single blood samples were taken on days 1, 8, 15, 29, 57, 64, 71, 85, 113, and 169 (end of study); pre-specified PK analysis took place on Days 1 and 57 | Mean Cmax values following Days 1 and 57 are presented. |
| Primary | Time to Cmax (Tmax) of Romosozumab | Single blood samples were taken on days 1, 8, 15, 29, 57, 64, 71, 85, 113, and 169 (end of study); pre-specified PK analysis took place on Days 1 and 57 | Median tmax values following Days 1 and 57 are presented. |
| Primary | Area Under the Serum Concentration Time Curve (AUC) From Time 0 to Day 28 (AUC[0-28]) of Romosozumab | Single blood samples were taken on days 1, 8, 15, 29, 57, 64, 71, and 85; pre-specified PK analysis took place on Days 1 and 57 | Mean AUC(0-28) values following Days 1 and 57 are presented. |
| Primary | Accumulation Ratio of Romosozumab | Single blood samples were taken on days 1, 8, 15, 29, 57, 64, 71, and 85; pre-specified PK analysis took place on Days 1 and 57 | The accumulation ratio was calculated as AUC(0-28) at Day 57/AUC(0-28) at Day 1. Mean accumulation ratio values based on analysis at Days 1 and 57 are presented, as pre-specified. |
| Primary | Terminal Half-life of Romosozumab | Single blood samples were taken on days 1, 8, 15, 29, 57, 64, 71, 85, 113, and 169 (end of study); pre-specified PK analysis took place on Day 57 | Median terminal half-life values at Day 57 are presented. |
| Secondary | Number of Participants With Treatment-Emergent Adverse Events (TEAEs) | Day 1 to end of study (up to Day 169); median duration on study was 5.55 months | TEAEs were adverse events (AEs) that started on or after first dose of investigational product up to the end of study (up to Day 169). Any clinically significant changes in vital signs, electrocardiogram parameters, physical exam findings, and clinical laboratory parameters were reported as TEAEs. Injection site reactions were events of interest (EOI) for this study. |
| Secondary | Number of Participants With Changes From Baseline in Cranial Nerve VII Examination Findings at Day 57, Day 85, and Day 169 | Baseline (Day 1), Day 57, Day 85, and Day 169 | Facial nerve (cranial nerve VII) function was assessed clinically by facial symmetry inspection at rest, followed by assessment of the symmetry of specific facial movements: raising eyebrows, closing the eyes, blowing out the cheeks, smiling, pursing and closing the lips. Results of the cranial nerve examination were classed as 0 = Normal; 1 = Abnormal not clinically significant; and 2 = Abnormal clinically significant. An increase from baseline indicates an increase in abnormal clinical findings on the cranial nerve VII examination. |
| Secondary | Number of Participants With Anti-romosozumab Antibodies | Blood samples for anti-romosozumab antibodies were taken Day 1, Day 15, Day 29, Day 85, and Day 169 | Treatment-boosted anti-romosozumab antibody was defined as binding antibody positive at baseline with a \>4 x increase in magnitude post-baseline. Transient results were defined as negative results at the participant's last time point tested within the study period. |
| Secondary | Percentage Change From Baseline in Serum Concentrations of Serum Type 1 Collagen C-Telopeptide (CTX) | Blood samples were taken Days 1 (baseline), 8, 15, 29, 57, 64, 71, 85, 113, and 169 | Serum concentrations of the bone turnover marker CTX were determined at pre-specified time points. |
| Secondary | Percentage Change From Baseline in Serum Concentrations of Procollagen Type 1 N-terminal Propeptide (P1NP) | Blood samples were taken Days 1 (baseline), 8, 15, 29, 57, 64, 71, 85, 113, and 169 | Serum concentrations of the bone turnover marker P1NP were determined at pre-specified time points. |
