Study summary

This is a randomized controlled trial in which patients with moderate to severe shoulder pain (Visual Analog Scale (VAS) > 40), in the setting of rotator cuff tendinopathy refractory to conservative treatment, will be enrolled.

The primary aim of the study is to estimate the effect of transcatheter arterial embolization (TAE) with physical therapy (PT) vs PT alone on the change in shoulder pain at 12-month follow up. Scientific objectives also include an assessment of safety of the intervention, assessment of changes in Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity score, Shoulder Pain and Disability Index (SPADI) scores, MRI Tendinopathy Score between the TAE + PT and PT groups.

Read the detailed description

This is a single center prospective randomized controlled study at Brigham \& Women's Hospital (BWH), a teaching hospital of Harvard Medical School. Patients with clinical and MRI findings of shoulder tendinopathy, moderate to severe shoulder pain (VAS > 40), and pain refractory to at least 6 months of physician directed conservative therapy will be eligible for enrollment.At screening patient will undergo a shoulder MRI to evaluate for tendinopathy, and patients with complete full thickness tendon tears will be excluded.

Patients will be randomized to either the TAE +PT or PT group. Patients in the TAE + PT group will undergo angiography to evaluate branch shoulder arteries for hyperemia. If hyperemia is present, then embolization will be performed. This treatment will be followed by 3 months of structured PT. Patients in the PT group will undergo 3-months of structured physical therapy with isolated eccentric exercises.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Male, female, transgender female, transgender male, non-binary

  2. Known history of anaphylaxis to iodinated contrast agents or gadolinium based contrast
  3. Acute kidney injury
  4. Allergy to poppy seeds or lipiodol
  5. Renal dysfunction as defined by serum creatinine >1.6 dl/mg or \<60 obtained within 30 days of procedure.

  11. Previous history of complete full-thickness tear of the rotator cuff
  12. Presence of non-MRI compatible devices (e.g., non-compatible cardiac pacemaker).
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

Study arms

  • Experimental
    Embolization

    Angiography will be performed to identify hyperemic neovasculature arising from one or more of branch shoulder arteries. After localizing the abnormal neovessels a microcatheter will be inserted coaxially and selectively placed in the targeted artery(ies). The abnormal vessels will be embolized with Lipiodol emulsion (Guerbet, Villepinte, France) The embolic agent will be used under an investigational device exemption from the FDA. The embolic will be injected in small volume increments until blood flow stagnates in the target artery(ies). Angiography and embolization will be repeated until the hyperemia is markedly reduced as demonstrated on digital subtraction angiography. Subjects will participate in structured physical therapy consisting of 3 months of eccentric strength training. This twelve-week program will consist of 4 PT sessions at week 0, week 4, week 8, and week 12.

What researchers measure

Primary outcomes

  1. Visual Analog Scale Pain (VAS) Score

    The difference in shoulder visual analog pain scale scores between TAE +PT and PT groups obtained 12 months following intervention vs. pre-intervention. The visual analog scale is ratio scale from 0 to 100 which measures pain symptoms. On this scale higher numbers indicated more severe pain symptoms.

    Time frame: 12 months

Secondary outcomes

  1. Adverse Events

    Compare the safety of TAE + PT relative to PT by recording adverse events at 1 month, 3 months, 6 months, and 12 months post intervention

    Time frame: 12 months

  2. Patient-Reported Outcomes Measurement Information System Upper Extremity

    Estimate the effect of TAE + PT vs PT on the change in Patient-Reported Outcomes Measurement Information System Upper Extremity scores at 1, 3, 6 and 12-months. A higher score indicates a better outcome. The scores can range from 15 to 61and are scored on what is called a T-score, a metric which reflects one standard deviation for each 10 points.

    Time frame: 12 months

  3. Shoulder Pain and Disability Index

    estimate the effect of TAE + PT vs PT on the change in Shoulder Pain and Disability Index scores at 1, 3, 6 and 12-months. The scale is a ratio scale of 0 to 130 with higher scores indicating greater degree of pain and disability.

    Time frame: 12 months

  4. MRI Tendinopathy scores

    Estimate the effect of TAE + PT vs PT on the change in MRI Tendinopathy scores at baseline and 12-months. The scale is ordinal and ranges from 0 to 3 with higher scores indicating a greater degree of tendinopathy.

    Time frame: 12 months
