About this study

Official title: Regenerative Medicine for Joint Hypermobility and Instability: A Prospective, Open-Label, Single-Arm, Step-Care Clinical Study

This clinical trial is designed to evaluate whether a stepwise injection-based treatment approach can reduce pain and improve function in adults with joint hypermobility, connective tissue laxity, and joint instability.

Joint hypermobility occurs when joints move beyond their normal range, often because of looser connective tissue. For some patients, this can contribute to chronic pain, recurrent instability, reduced function, and disability. This study focuses on adults with hypermobile Ehlers-Danlos syndrome (hEDS), hypermobility spectrum disorder (HSD), or joint instability after injury who have already completed physical therapy without adequate relief.

Read more

The main question this study aims to answer is whether the first treatment step, dextrose prolotherapy, can reduce pain by 40% or more two weeks after the second injection.

Participants will receive treatment in a step-by-step sequence, based on their response:

Step 1: Dextrose prolotherapy A dextrose-based injection used to stimulate a healing response in ligament, tendon, or joint-supporting tissue.

Step 2: Platelet-rich plasma (PRP) An injection prepared from the participant's own blood, designed to support tissue repair and recovery.

Step 3: Doxycycline injections A low-dose injectable treatment used in this study to help protect joint-supporting tissue. It is not being used to treat infection.

Alternative option: Hyaluronic acid injections An injection into the joint that may be offered if the earlier treatment steps do not provide enough improvement.

Each treatment step begins with two injections, given approximately two weeks apart. If a participant improves by 40% or more, they may continue with that treatment pathway. If they do not improve enough, they may be offered the next step in the study.

Participants will be followed for up to 12 months, with study visits used to monitor pain, function, treatment response, and safety.

Read the detailed description

This is a prospective, open-label, single-arm, step-care interventional study evaluating a structured regenerative medicine treatment protocol for adults with symptomatic joint hypermobility or instability who have failed conservative therapy including physical therapy.

All eligible participants begin with dextrose prolotherapy (20% final concentration). Response is assessed at 2 weeks after the second injection using the Global Percentage of Improvement (GPI) scale. Participants who improve by 40% or more continue with that treatment. Those who do not improve enough are offered the next treatment in the sequence.

The step-care sequence is:

Phase 1: Dextrose prolotherapy (20% dextrose with local anesthetic) Phase 2: Autologous platelet-rich plasma (PRP) prolotherapy Phase 3: Investigational injectable doxycycline hyclate prolotherapy (10 mg/mL; 5-25 mg per joint site; maximum 100 mg per session) Alternative pathway: Visco-3 hyaluronic acid viscosupplementation (FDA-approved for knee osteoarthritis; off-label use in other joints disclosed in consent)

Each phase follows the same cycle: 2 injections approximately 2 weeks apart, followed by a decision point at 2 weeks after the second injection. The dextrose phase decision point is the study primary endpoint.

Outcome measures collected include the Brief Pain Inventory (BPI), Global Percentage of Improvement (GPI), and region-appropriate joint-specific functional measures (DASH for upper extremity, KOOS for knee, LEFS for lower extremity, ODI for spine). Long-term follow-up occurs at 3, 6, and 12 months.

Safety is monitored continuously. An Independent Medical Monitor reviews all serious adverse events. The injectable doxycycline use is investigational; an IND exemption determination request has been submitted to the FDA. Enrollment into the doxycycline phase will not begin until the FDA determination is received and IRB approval is in place.

The study is investigator-initiated with no external funding. It is conducted at a single site - Manhattan Pain Medicine, New York, NY.

What is being measured

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

  1. Global Percentage of Improvement (GPI) Responder Rate After Dextrose Prolotherapy

    Proportion of participants achieving at least 40% improvement on the Global Percentage of Improvement (GPI) scale relative to baseline. The GPI is a validated patient-reported outcome measure used in prolotherapy research in which participants rate their overall percentage of improvement from 0% (no improvement) to 100% (complete improvement). A participant is classified as a responder if they report 40% or greater improvement. This threshold also serves as the step-care decision rule: responders continue dextrose; non-responders are offered rotation to the next treatment.

    Measured: 2 weeks after the second dextrose prolotherapy injection (approximately 4 weeks after enrollment)

Secondary outcomes (14)

  1. Change in Brief Pain Inventory (BPI) Pain Severity Score

    Change from baseline in the Brief Pain Inventory (BPI) pain severity subscale, a validated 4-item patient-reported measure assessing worst, least, average, and current pain on a 0-10 numeric rating scale. Scores range from 0 to 10, where 0 indicates no pain and 10 indicates pain as bad as you can imagine. Higher scores indicate worse outcome.

    Measured: Baseline, 2 weeks after second injection of each phase, and at 3, 6, and 12 months

  2. Change in Brief Pain Inventory (BPI) Pain Interference Score

    Change from baseline in the Brief Pain Inventory (BPI) interference subscale, a validated 7-item patient-reported measure assessing how pain interferes with general activity, mood, walking, work, relationships, sleep, and enjoyment of life on a 0-10 numeric rating scale. Scores range from 0 to 10 per item and are averaged to a total interference score of 0 to 10, where 0 indicates no interference and 10 indicates complete interference. Higher scores indicate worse outcome.

    Measured: Baseline, 2 weeks after second injection of each phase, and at 3, 6, and 12 months

  3. Change in Disabilities of the Arm, Shoulder and Hand (DASH) Score

    Change from baseline in the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, a validated 30-item patient-reported outcome measure assessing physical function and symptoms in people with musculoskeletal disorders of the upper extremity. Scores range from 0 to 100, where 0 indicates no disability and 100 indicates maximum disability. Higher scores indicate worse outcome. Administered to participants whose primary target joint is in the upper extremity.

    Measured: Baseline, 2 weeks after second injection of each phase, and at 3, 6, and 12 months

  4. Change in Knee Injury and Osteoarthritis Outcome Score (KOOS)

    Change from baseline in the Knee Injury and Osteoarthritis Outcome Score (KOOS), a validated patient-reported outcome measure assessing symptoms, pain, function in daily living, function in sport and recreation, and knee-related quality of life. Each of five subscales is scored from 0 to 100, where 0 indicates extreme problems and 100 indicates no problems. Higher scores indicate better outcome. Administered to participants whose primary target joint is the knee.

    Measured: Baseline, 2 weeks after second injection of each phase, and at 3, 6, and 12 months

  5. Change in Lower Extremity Functional Scale (LEFS) Score

    Change from baseline in the Lower Extremity Functional Scale (LEFS), a validated 20-item patient-reported outcome measure assessing function in people with lower extremity musculoskeletal conditions. Scores range from 0 to 80, where 0 indicates inability to perform any activities and 80 indicates no difficulty with any activities. Higher scores indicate better outcome. Administered to participants whose primary target joint is in the lower extremity (excluding knee).

    Measured: Baseline, 2 weeks after second injection of each phase, and at 3, 6, and 12 months

  6. Change in Oswestry Disability Index (ODI) Score

    Change from baseline in the Oswestry Disability Index (ODI), a validated 10-item patient-reported outcome measure assessing degree of disability and quality of life in people with low back pain. Scores range from 0 to 100, where 0 indicates no disability and 100 indicates maximum disability. Higher scores indicate worse outcome. Administered to participants whose primary target joint is in the spine.

    Measured: Baseline, 2 weeks after second injection of each phase, and at 3, 6, and 12 months

  7. Global Percentage of Improvement (GPI) Responder Rate After PRP Prolotherapy

    Proportion of participants rotated to platelet-rich plasma (PRP) prolotherapy who achieve at least 40% improvement on the GPI scale at the PRP phase decision point, among participants who did not respond to dextrose prolotherapy.

    Measured: 2 weeks after the second PRP prolotherapy injection

  8. Global Percentage of Improvement (GPI) Responder Rate After Doxycycline Prolotherapy

    Proportion of participants rotated to investigational doxycycline prolotherapy who achieve at least 40% improvement on the GPI scale at the doxycycline phase decision point, among participants who did not respond to dextrose and PRP prolotherapy.

    Measured: 2 weeks after the second doxycycline prolotherapy injection

  9. Global Percentage of Improvement (GPI) Response After Hyaluronic Acid Viscosupplementation

    GPI score at end-of-course assessment among participants who entered the alternative hyaluronic acid (HA) viscosupplementation pathway after failure of or adverse reaction to regenerative phases. Reported descriptively; not compared to regenerative phase outcomes.

    Measured: 2 weeks after the final hyaluronic acid injection of the course

  10. Durability of Response: Global Percentage of Improvement (GPI) Score at 3, 6, and 12 Months

    Global Percentage of Improvement (GPI) score at 3, 6, and 12 months from the primary endpoint assessment, evaluating maintenance of treatment response and need for additional treatment over time. The GPI is a patient-reported scale ranging from 0% to 100%, where 0% indicates no improvement and 100% indicates complete improvement relative to baseline. Higher scores indicate better outcome.

    Measured: 3 months, 6 months, and 12 months from primary endpoint

  11. Durability of Response: Brief Pain Inventory (BPI) Pain Severity Score at 3, 6, and 12 Months

    Brief Pain Inventory (BPI) pain severity subscale score at 3, 6, and 12 months from the primary endpoint assessment, evaluating maintenance of pain reduction over time. Scores range from 0 to 10, where 0 indicates no pain and 10 indicates pain as bad as you can imagine. Higher scores indicate worse outcome.

    Measured: 3 months, 6 months, and 12 months from primary endpoint

  12. Durability of Response: Brief Pain Inventory (BPI) Pain Interference Score at 3, 6, and 12 Months

    Brief Pain Inventory (BPI) pain interference subscale score at 3, 6, and 12 months from the primary endpoint assessment, evaluating maintenance of functional improvement over time. Scores range from 0 to 10, where 0 indicates no interference and 10 indicates complete interference with daily activities. Higher scores indicate worse outcome.

    Measured: 3 months, 6 months, and 12 months from primary endpoint

Model description
All participants begin with dextrose prolotherapy. Response is assessed at 2 weeks after the second injection using the Global Percentage of Improvement (GPI) scale. Participants who improve by 40% or more continue with the same treatment. Those who do not improve enough are offered the next treatment in the sequence: platelet-rich plasma (PRP) prolotherapy, then investigational doxycycline prolotherapy. A hyaluronic acid viscosupplementation pathway is available as an alternative for participants who do not respond to or cannot tolerate the regenerative treatments. Not all participants will receive all treatments - progression through the steps depends on each participant's response.

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 22 inclusion and 16 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: opening soon, as of the sponsor's last update on 6 Oct 2026. 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.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Mariia Safroshkina, MD, Medical Doctor (2139329721, research@manhattanpainmedicine.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Global Percentage of Improvement (GPI) Responder Rate After Dextrose Prolotherapy (time frame: 2 weeks after the second dextrose prolotherapy injection (approximately 4 weeks after enrollment)). 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 NCT07688096, which also lists 29 linked publications.

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 6 Oct 2026.
