About this study

Calcific tendinitis of the rotator cuff is a common cause of chronic pain of the shoulder. US- guided needling and lavage of the calcification is one of the therapeutic options after failure of conservative management with physiotherapy and anti-inflammatory drugs. The goal of this procedure is to remove the calcific deposit that is believed to cause the sub-acromial impingement. However, studies have shown that complete and rapid disappearance of the calcification deposit after irrigation is rare. The treatment is thought to promote the spontaneous resorption that occurs the weeks and months after the procedure. However, due to this slow process, time to complete recovery can be long. Moreover, it has been shown an association between the amount of removed calcium and improved outcome. Therefore, there is a need to find a way to remove quickly and completely the calcific deposit after irrigation. Sodium thiosulfate has been used successfully in the treatment of calciphylaxis and subcutaneous calcification deposit. The mechanism of action involves chelation of calcium into calcium thiosulfate salts which are much more soluble than other salts of calcium. Our hypothesis is that injection of sodium thiosulfate after irrigation of the calcification will help to dissolve the calcific deposit and thus prompt the disappearance of the calcification.

    Measured: 1 month

Secondary outcomes (7)
  1. VAS pain during daily activity (0-10)

    Measured: 7 days, 1 month and 3 months

  2. VAS pain at rest (0-10)

    Measured: 7 days, 1 month and 3 months

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

    Measured: 1 month and 3 months

  4. Size of the calcific deposit assessed by X-Ray of the affected shoulder

    Measured: 7 days, 1 month and 3 months

  5. Size of the calcific deposit assessed by ultrasound of the affected shoulder

    Measured: 7 days, 1 month and 3 months

  6. Self-reported quality of life assessed by the EQ-5D questionnaire

    Measured: 1 month and 3 months

  7. Number of day off work due to the shoulder pain

    Measured: up to 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Sodium thiosulfate in people with Calcific Tendinitis of the Rotator Cuff, run by Nantes University Hospital 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?

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 14 Sep 2026. 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.

What does this phase mean?

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?

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?

Decrease the size of the calcific deposit after the PFL (time frame: 1 month). 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 NCT02538939, 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 14 Sep 2026.
