Clinical Trial Summary

Randomized pilot clinical trial to demonstrate superiority of bisphosphonate-magnesium combination over bisphosphonates alone in postmenopausal osteoporosis in slowing bone remodeling as assessed by C-terminal telopeptide of bone collagen type 1 (CTX) dosage.

Description:

A pilot, randomized, controlled, open-label, single-center, two-parallel-arm clinical trial testing the addition of oral magnesium supplementation to prescribed drug therapy in the care setting. Category 1.

The primary objective of this randomized trial is to demonstrate the superiority of the combination of bisphosphonates and magnesium over bisphosphonates alone in postmenopausal osteoporosis, in terms of slowing bone remodeling, as assessed by the measurement of C-terminal telopeptides of type 1 bone collagen (CTX).

The secondary objectives are to study the impact of magnesium supplementation at 1 year on:

1. the evolution of other biological markers of bone remodeling (by creating a collection of biological samples) and bone densitometry on the following sites: spine, femoral neck, total femur,

2. the evolution of cardiovascular parameters,

3. the follow-up of the incidence of fractures,

4. the evolution of sarcopenia,

5. the evolution of quality of life and pain,

6. the genetic predisposition of osteoporosis including the confirmation of known genetic markers and the potential identification of new genetic variants involved (by creating a biobank),

7. the epigenetic biomarkers in the osteoporosis patient population (by creating a biobank),

8. the role of the microbiota in osteoporosis patients (by creating a biobank),

9. the occurrence of adverse events.

As part of their usual care and management, patients will be diagnosed with osteoporosis and prescribed bisphosphonates.

Patients will have 3 or 4 visits depending on which group they are randomized to: a first screening visit as part of routine care, which will take place in the Rheumatology Department of the Clermont-Ferrand University Hospital, then 2 visits for patients in the "bisphosphonates alone" group and 3 visits for patients in the "bisphosphonates associated with magnesium" group, which will take place in the Inserm 1405 Clinical Investigation Platform/Clinical Investigation Center (PIC/CIC) of the Clermont-Ferrand University Hospital.

Visit 0 - Screening visit and diagnosis of osteoporosis (1 month before day 0): Rheumatology Department

During this visit, the investigator physician will perform various examinations and tests usually performed as part of the patient's usual care and management in order to establish a diagnosis of osteoporosis.

These examinations are as follow:

• Bone densitometry less than one year using Dual X-ray Absorptiometry (DXA), either previously performed by the patient or prescribed at this consultation.

• Bone biological assessment, including the following tests: Complete Blood Count (CBC), platelets, C-Reactive Protein (CRP), urea, creatinine with CKD-EPI clearance calculation, liver enzymes (AST, ALT), serum calcium, serum calcium corrected by albumin, serum phosphorus, serum protein electrophoresis, Thyroid Stimulating Hormone (TSH), 25 OH vitamin D, serum CTX.

Some patients who require profile radiographs of the spine will have this examination added for the consultation, especially for the evaluation of vertebral fractures if the context justifies it. Other patients will also have these x-rays to calculate the abdominal aortic calcification score (Kauppila score).

Body composition will be requested during the bone densitometry evaluation on the DXA machine.

Once the diagnosis of osteoporosis is confirmed, the physician will propose to eligible patients to participate in this research protocol by explaining the objectives and the course of the study, and give them an information note.

If the patients are interested, the investigator physician will prescribe osteoporotic treatment to be started after the Visit 1: Day 0 inclusion visit.

Visit 1 - Inclusion visit (Day 0): PIC/CIC (2 hours)

During this visit, the physician will explain again the objectives and progress of the study with the different tests and questionnaires planned so that the patients can give their informed consent to participate.

During this visit, the following will be performed:

• A medical examination,

• A blood sample to measure magnesium levels and to obtain a collection of biological samples in order to:

1. Evaluate bone biomarkers (osteocalcin, sclerostin, periostin, irisin, N-terminal propeptide of procollagen type 1 (P1NP), Dickkopf-related protein 1 (DKK1)),

2. Characterize genetic predispositions of osteoporosis,

3. Characterize epigenetic biomarkers in the osteoporosis patient population by microRNA analysis,

• A stool sample to obtain a biobank for subsequent microbiota analysis.

• A cardiovascular exploration based on the measurement of the increase in the diameter of the brachial artery (FMD, "Flow-Mediated Dilation"); measurement of the increase in digital volume (RHI, "Reactive Hyperemia Index") and measurement of the microcirculatory perfusion of the skin at the level of the hand (FLD, "Flow Laser Doppler"), and measurement of the stiffness of the main arteries (aorta) by the technique of Pulse Wave Velocity (PWV) measurement.

• Exploration of sarcopenia: the following questionnaires and tests will be performed:

SARC-F (Strength, Assistance with walking, Rising from a chair, Climbing stars, and Falls), SPPB (Short Physical Performance Battery), the measurement of the muscular function and DXA with the measurement of the body composition.

• Pain exploration: Numerical Pain Scale (NPS), Brief Pain Inventory (BPI), and pain thresholds.

• Quality of life component questionnaires: Pittsburgh Sleep Quality Index (PSQI), the Hospital Anxiety and Depression scale (HADs) and the 36-Item Short Form Survey (SF-36).

• Randomization into two groups: a "bisphosphonates associated with magnesium" group, and a "bisphosphonates alone" group.

• Delivery of a daily follow-up diary to evaluate the average pain per day, the consumption of analgesics, and the occurrence of any adverse effects.

For the "bisphosphonates alone" group, this diary will be completed for the first month of taking bisphosphonates (Month 1) as well as for the last month before the end of study visit at one year (Month 12).

For the "bisphosphonates combined with magnesium" group, a diary will also be given to them for the first month of taking bisphosphonates and a second will be given to them at visit 2 which will cover the period of taking magnesium over the last 3 months preceding the end-of-study visit (Months 10 to 12).

Visit 2 only for patients in the bisphosphonate-magnesium arm (Day 0+9 months): PIC/CIC (15 minutes)

At this visit, 9 months after the start of the trial, a blood test will be performed to measure magnesium levels, and then patients will be given magnesium treatment to take daily for 3 months before their 1-year visit (during months 10, 11 and 12). Finally, they will be given a follow-up diary to evaluate the average pain per Numerical Pain Scale, the daily consumption of analgesics, and the occurrence of possible adverse effects.

→ In addition, for the patients in this group, a phone call will be made by the project team 6 weeks after the start of the magnesium treatment to ensure good tolerance and compliance with the magnesium intake.

Visit 3 - End of study visit at 1 year (Day 0+1 year): PIC/CIC (1h15)

During this visit, the following examinations, tests and questionnaires will be performed:

• A medical examination,

• A blood sample to measure magnesium levels, serum CTX and other biological bone markers (osteocalcin, sclerostin, periostin, irisin, P1NP, DKK1) and to perform microRNA analysis by collecting biological samples,

• A stool sample to study the microbiota (constitution of a collection of biological samples),

• A bone densitometry measurement (DXA),

• A cardiovascular exploration with FMD, RHI, FLD and PWV measurements and an estimation of the Kauppila score.

• Exploration of sarcopenia: questionnaires and tests SARC-F, SPPB, measurement of muscle function and body composition.

• Exploration of pain: NPS, BPI, and pain thresholds.

• Quality of life component questionnaires: PSQI, HADs and the SF-36. As part of routine care, patients will then be seen in a follow-up rheumatology consultation to confirm the indication for continuing treatment with biphosphonates, with a blood test identical to that performed during the pre-selection visit.

Visit 3 will be the last visit of the study.

Secondary	Endothelial dysfunction measured by FMD (Flow-Mediated Dilation)	FMD is a non-invasive technique. It was assessed using an ultrasound approach with a high-resolution linear array transducer coupled with computer-assisted analysis software. With this software, changes in the brachial artery could be assessed in real-time through an automated edge detection system. Longitudinal images of the brachial artery were obtained with the transducer fixed on the medial aspect of the dominant arm, approximately 2 cm above the medial epicondyle of the humerus. The transducer was fixed on the arm by a special arm-holding device. The brachial artery diameter was acquired as per a 30 s baseline measure, after which a cuff was placed around forearm (3 cm above wrist) and inflated to 250 mm Hg for 5 min. After cuff deflation, the brachial artery diameter was continuously monitored for 2-4 min to detect the peak artery diameter. FMD was determined as the percentage change in diameter from baseline to peak arterial diameter.	Visit 1: Day 0

The determination of each threshold will be established by an average of three measurements.	Visit 3: Day 0+1 year
Secondary	Central sensitization tests, measurement of the Conditioned Pain Modulation (CPM) effect	The patients are seated, the ATS thermode associated with the Pathway is applied to the dominant forearm. From the baseline value of 32°C, the Pathway delivers a "Pain 60 / Test stimulus" for 10 seconds, and the patient scores the pain on a visual numerical scale from 0 to 100. Then, the Pathway delivers a "Pain 60 / Test stimulus" for 30 seconds, and the patient scores the pain on the same scale. Fifteen minutes after the end of the two stimulations, the patient immersed the non-dominant arm for 60 seconds in a water bath at 46.5°C. Then a second identical sequence of 10 and 30 second stimulations was performed, with the scores recorded after each stimulation on the visual numerical scale from 0 to 100. The CPM effect is measured by taking the difference between the pain scores on the visual numerical scale before and after immersion.	Visit 1: Day 0

Secondary	The Pittsburgh Sleep Quality Index (PSQI)	The PSQI is a self-administered questionnaire with 19 items. It was developed to measure sleep quality in the month prior to the patient interview. This questionnaire includes 7 components: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, hypnotic medication use and daytime dysfunction.; The global score (0 to 21) is obtained by adding the sub-scores of the 7 components, each ranging from 0 to 3 points. In the absence of an answer to one or more questions, the subtotal using this question cannot be calculated and will affect the overall score.; The higher the overall score, the greater the impairment in sleep quality. An overall score >5 is an indicator of sleep disturbance.	Visit 1: Day 0

Secondary	The 36-Item Short Form Survey (SF-36)	The quality of life of patients is assessed by the general questionnaire 36-Item Short Form Survey (SF-36) which can be administered by self or hetero-questionnaire. The SF-36 questionnaire was developed from the Medical Outcome Study, a 149-item questionnaire that was developed to assess how the American healthcare system affects the outcome of care. The SF-36 questionnaire is composed of 36 items and makes it possible to assess the physical and mental health of an individual using eleven questions relating to eight aspects of health: Physical activity, limitations due to physical state, physical pain, perceived health, vitality, life and relationship with others, limitations due to the mental state and mental health. Scores between 0 and 100 are determined. Scores tending towards 100 indicate a better quality of life.	Visit 1: Day 0

Secondary	The Hospital Anxiety and Depression Scale (HAD)	It is a self-administered questionnaire completed by the patient and based on the Hamilton scale. The HAD scale is a tool for screening for anxiety and depressive disorders. It includes 14 items rated from 0 to 3. Seven questions relate to anxiety (total A) and seven others to the depressive dimension (total D), thus making it possible to obtain two scores (maximum score for each score = 21).; To screen for anxiety and depressive symptomatology, the following interpretation can be proposed for each of the scores (A and D): = 7: normal case; 8 to 10: borderline case; = 11: abnormal case.
