Trial summary

Osteogenesis Imperfecta (OI) is a heterogeneous group of rare connective tissue hereditary diseases responsible for fragility and bone deformity. OI is caused by an autosomal dominant mutation of COL1A1 or COL1A2, encoding α1 and α2 of the collagen, regardless of their phenotypic severity (1 to 5 OI type). Read more about this study

About this study

Osteogenesis Imperfecta (OI) is a heterogeneous group of rare connective tissue hereditary diseases responsible for fragility and bone deformity. OI is caused by an autosomal dominant mutation of COL1A1 or COL1A2, encoding α1 and α2 of the collagen, regardless of their phenotypic severity (1 to 5 OI type).

This observation suggests the existence of a undetermined mechanism that may be found in epigenetic regulation, including particularly micro Ribonucleic Acids (miRs).

Indeed, these small non-coding miRs are involved in the regulation of major steps of cellular processes in different pathologies, especially in bone disease.

Currently, no study can provide a satisfactory answer.

This is an etiologic study to reveal the correlation between micro-RNAs (miR) expression and the type I or III of the Osteogenesis Imperfecta (OI).

The aim of this study is therefore to identify miRs significantly associated with the severity of OI.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. micro Ribonucleic Acids (miRs) expression in serum of the patients Osteogenesis imperfecta (OI) type I or III versus control population

    Identification of specific miRs expressed in the serum of OI patients using NGS (Next Generation Sequencing).

    Measured: up to 1 month (after inclusion)

Secondary outcomes (7)
  1. Nature of micro Ribonucleic Acids (miRs) identified by Next-Gen Sequencing (NGS )

    Compare the nature of the miRs identified by NGS (Next Generation Sequencing) in serum between the 3 groups of subjects: type 1 Osteogenesis Imperfecta (OI), type 3 OI and controls (controls are patients with osteoarthritis).

    Measured: Up to 1 month (after inclusion)

  2. Level of expression of micro Ribonucleic Acids (miRs) identified by Next-Gen Sequencing (NGS )

    The objective is to validate expression of miRs identified by NGS (Next Generation Sequencing) in blood samples of patients from 3 groups: an Osteogenesis imperfecta (OI) type 1 cohort and an OI type 3 cohort, recruited for the study, and a pre-existing group of control patients (issued from cohorts OFELY and MODAM for women, STRAMBO for men).

    Expression of the significant miRs identified by NGS will be measured by Reverse Transcription Quantitative Polymerase Chain Reaction (RT-qPCR) and then these results will be compared with same analysis on blood samples of control patients.

    Measured: Up to 1 month (after inclusion)

  3. Presence of fracture

    Severity of OI will be evaluated using radiological data (fracture) extracted from patients' medical records. Association between expression of miRs in patients with OI with the severity of the disease will be studied by statistical analysis.

    Measured: Up to 1 month (after inclusion)

  4. Presence of biochemical markers of bone turnover in blood

    Severity of OI will be evaluated using biological data (biochemical markers of bone turnover) extracted from patients' medical records. Association between expression of miRs in patients with OI with the severity of the disease will be studied by statistical analysis.

    Measured: Up to 1 month (after inclusion)

  5. Bone pain

    Severity of OI will be evaluated using clinical data (bone pain mesured on Visual Analogue Scale) extracted from patients' medical records. Association between expression of miRs in patients with OI with the severity of the disease will be studied by statistical analysis.

    Measured: Up to 1 month (after inclusion)

  6. Quality of life

    Investigators will use a specific questionnaire completed by a rheumatologist at inclusion to obtain more information about a patient's lifestyle. The higher the score the more severe the disease impact and vice versa. Association between expression of miRs in patients with OI with the severity of the disease will be studied by statistical analysis.

    Measured: Up to 1 month (after inclusion)

  7. Assessment of environmental factors

    The investigating team will use information extracted from patients' medical records to obtain environmental information, which includes using a specific questionnaire completed by a rheumatologist with patients at inclusion.

    Association between expression of miRs in patients with OI with the environmental data will be studied by statistics analysis.

    Measured: Up to 1 month (after inclusion)

Questions about this trial

What is this clinical trial studying?

A study testing Blood sample in people with Osteogenesis Imperfecta, run by Hospices Civils de Lyon at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

micro Ribonucleic Acids (miRs) expression in serum of the patients Osteogenesis imperfecta (OI) type I or III versus control population (time frame: up to 1 month (after inclusion)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04009733, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Sep 2025.
