Who may be able to join

  • Cohort 1: 40 volunteers, free from bone disease:
  • Participants must be free from bone disease and not have a family history of OI;
  • Participants to be age and sex matched with OP participants may be recruited among individuals attending the RNOH Metabolic Unit for DXA scanning, who are shown to have normal bone density T score> -2.5;

  • Controls will be sex and age matched (within five years) to the disease cohort patients.
  • Children and adults both required
  • Cohort 2: 40 patients with OI:
  • Patients must have been clinically diagnosed with OI;
  • Where possible participants will be identified from the Royal National Orthopaedic Hospital, Metabolic Unit database; if not from RNOH then diagnosis will be otherwise confirmed
  • Cohort 3: 40 patients with OA:
  • Patients must have been clinically diagnosed with OA;

  • 20 Adults and 20 children
  • Where possible participants will be identified from the Royal National Orthopaedic Hospital, Metabolic Unit database; if not from RNOH then diagnosis will be otherwise confirmed
  • Where possible measurements will be acquired prior to the start of treatment and then for up to 4 follow up visits at flexible time points to allow scheduling to coincide with hospital appointments. The minimum time between visits should be 2 months.

Official title: Development of a Novel, Safe Method for the Non-invasive Assessment of Human Bone Quality, In Vivo, Using Spatially Offset Raman Spectroscopy

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • spatially offset Raman spectrometer (SORS)Device

    Raman spectra will be collected non-invasively from patients using a lower power 830 nm laser. A probe is brought into gentle contact with the patients skin and measurements taken. The laser power has a pre-defined safe threshold of 30 mW into a 3.5 mm diameter aperture. Built in device safety features prevent this threshold from being exceeded. The probe that comes into patient contact is suitable for disinfecting.

What is being measured

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

  1. SORS Raman spectral fingerprint for bone disease types and changes over time

    Individual patient data will be pre-processed and extracted after patient participation visits. As cohorts are filled multivariate classification models will be built to validate disease discrimination and validation of the SORS technique.

    Measured: SORS Raman spectral features will be evaluated using a variety of multi-variate analytical tools e.g. BTEM at time zero and a repeat measure within a year.

Questions about this trial

What is this clinical trial studying?

An observational study of Osteoarthritis and Osteoporosis, run by University College, London.

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 41 inclusion and 0 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: status not confirmed, as of the sponsor's last update on 23 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

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?

SORS Raman spectral fingerprint for bone disease types and changes over time (time frame: SORS Raman spectral features will be evaluated using a variety of multi-variate analytical tools e.g. BTEM at time zero and a repeat measure within a year.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 23 Nov 2022.
