Brief summary
The study will be a multi-center, randomized, open label, parallel trial conducted in rheumatoid arthritis patients treated with glucocorticoids. After signing the informed consent, all patients will be screened as per the inclusion and exclusion criteria. Estimated 314 eligible patients will be enrolled. The enrolled patients will be randomly assigned to either Eldecalcitol group or Alfacalcidol group in a 1:1 ratio and followed up for 12 months. On-site follow up visits will be conducted at Month 6 and 12 after enrollment. The study is designed to evaluate the efficacy and safety of Eldecalcitol in preventing glucocorticoid-induced bone loss in rheumatoid arthritis patients.
Detailed description
After having signed informed consent (Day 0), the patients will be screened for enrollment. About 314 eligible patients will be enrolled in this study. The background information of eligible patients including demographic characteristics, history of present illness, medical history, treatment history, etc., related questionnaire, baseline bone mineral density (BMD), X-ray examination result, High Resolution-Peripheral Quantitative Computed Tomography (HR-pQCT) examination result, quantitative ultrasound (QUS) examination result and lab test result will be collected at Day 0. After enrollment, the following information will be collected at 6 months and/or 12 months: related questionnaire, BMD, X-ray examination result, HR-pQCT examination result, QUS examination result and lab test result, medication adherence and AE information.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percent change from baseline to month 12 in lumbar spine (L1-4) bone mineral density (BMD) | Baseline and 12 months | BMD will be measured using dual energy x-ray absorptiometry (DXA). Images will be analyzed by blinded independent central review. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percent change from baseline to month 6 in lumbar spine (L1-4) BMD | Baseline and 6 months | BMD will be measured using DXA. Images will be analyzed by blinded independent central review. |
| Percent change from baseline in total hip BMD | Baseline, 6 months and 12 months | BMD will be measured using DXA. Images will be analyzed by blinded independent central review. |
| Percent change from baseline in femoral neck BMD | Baseline, 6 months and 12 months | BMD will be measured using DXA. Images will be analyzed by blinded independent central review. |
| Percent change from baseline to month 12 in broadband ultrasound attenuation (BUA) and speed of sound (SOS) measured by quantitative ultrasound (QUS) | Baseline and 12 months | Broadband ultrasound attenuation (BUA) and speed of sound (SOS) will be measured by quantitative ultrasound (QUS). |
| Percent change from baseline in Procollagen Type 1 N-telopeptide (P1NP) | Baseline, 6 months and 12 months | Serum P1NP will be tested |
| Percent change from baseline in Type 1 Collagen C-telopeptide (CTX) | Baseline, 6 months and 12 months | Serum CTX will be tested |
| Percentage of patients diagnosed with osteoporosis at month 12 | Baseline and 12 months | — |
| Incidence of new vertebral fracture | Baseline and 12 months | New vertebral fracture will be confirmed by the lateral X-ray of thoracic/lumbar vertebrae |
| Change from baseline in Quality of Life assessed using EQ-5D-5L | Baseline, 6 months and 12 months | The EQ-5D-5L represents a global quality of life measure that includes multiple components potentially impacted by the anti-anginal treatments being examined. The EQ-5D-5L score includes questions on mobility, self-care, usual activities, anxiety/depression, and pain/discomfort on a 5-point scale: 1=No Problem, 2=Slight Problem, 3=Moderate Problem, 4=Severe Problem, 5=Extreme Problem or Inability. 0, 1, and negative values corresponding to death, full health, and health states worse than death, respectively. Higher scores indicated greater levels of problems across each of the five dimensions. |
| Change from baseline in the Health Assessment Questionnaire-Disability Index (HAQ-DI) | Baseline, 6 months and 12 months | Physical function was assessed by HAQ-DI. It consisted of at least 2 questions per category, participant reported assessment of ability to perform tasks in 8 categories of daily living activities: dress/groom; arise; eat; walk; reach; grip; hygiene; and common activities over past week rated on a 4-point scale where 0 = no difficulty; 1 = some difficulty; 2 = much difficulty; 3 = unable to do. Overall score was computed as the sum of category scores and divided by the number of categories answered, ranging from 0 to 3, where 0 = no disability and 3 = unable to do, high-dependency disability. |
| Change from baseline in Disease Activity Score for 28 Joints -C-Reactive Protein (DAS28--CRP) Score | Baseline, 6 months and 12 months | DAS28 is a composite score that includes 4 variables: TJC (based on 28 joints); SJC (based on 28 joints); General health (GH) assessment by the participant assessed from the ACR rheumatoid arthritis (RA) core set questionnaire (participant global assessment) in 100 mm visual analog scale (VAS). Marker of inflammation assessed by the high sensitivity C-reactive protein (hs-CRP) in mg/L. The DAS28 score provides a number indicating the current disease activity of the RA. DAS28 total score ranges from 2-10. A DAS28 score above 5.1 means high disease activity, whereas a DAS28 score below 3.2 indicates low disease activity and a DAS28 score below 2.6 means disease remission. |
| Percent change from baseline to month 12 in volumetric bone mineral density (vBMD) measured by High Resolution-Peripheral Quantitative Computed Tomography (HR-pQCT) | Baseline and 12 months | The vBMD includes several individual parameters as total volumetric bone mineral density (Tt.vBMD), trabecular volumetric bone density (Tb.vBMD), and cortical volumetric density (Ct.vBMD) which all in milligram/cubic centimetre. |
| Percent change from baseline to month 12 in bone microarchitecture measured by High Resolution-Peripheral Quantitative Computed Tomography (HR-pQCT) | Baseline and 12 months | The bone microarchitecture include several individual parameters as trabecular bone volume fraction (BV/TV) in %, trabecular number (Tb.N) in 1/millimeter, trabecular thickness (Tb.Th) in millimeter, trabecular separation (Tb.Sp) in millimeter, cortical thickness(Ct.Th) in millimeter, and cortical porosity (Ct.Po) in %. |
| Percent change from baseline to month 12 in bone geometry measured by High Resolution-Peripheral Quantitative Computed Tomography (HR-pQCT) | Baseline and 12 months | The bone geometry include several individual parameters as total bone cross-sectional area (Tt.Ar), cortical area (Ct.Ar), and trabecular area (Tb.Ar) which all in square millimeter. |
