About this study

Official title: A Randomized Clinical Trial Evaluating Allogeneic Adipose-derived MesenchymAl Stem Cells as a Treatment of Dry Eye Disease in Patients With Sjögren's Syndrome

AMASS is a double-blinded randomized clinical trial with the purpose of investigating whether injection of allogeneic adipose-derived mesenchymal stem cells (ASCs) into the lacrimal gland (LG) results in increased ocular comfort compared to placebo.

Read the detailed description

AMASS is a double-blinded randomized clinical trial which will be performed at the Department of Ophthalmology, University Hospital of Copenhagen, Denmark. 40 patients with severe aqueous deficient dry eye disease (ADDE) due to Sjögren's Syndrome (SS) will be recruited from the Dept. of Ophthalmology, Rigshospitalet, and allocated in ratio 1:1 to either injection of allogeneic adipose-derived mesenchymal stem cells (ASCs) or placebo (vehicle, Crystore CS10) into the lacrimal gland (LG) in one eye. We hypothesize that injection of allogeneic ASCs into the LG increases tear production and reduce inflammation resulting in increased ocular comfort compared to placebo.

Being tested
ASCs, Cryostor CS10

What participants receive

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

  • ASCsDrug

    Also called Allogeneic adipose-derived mesenchymal stem cells

    ASCs expanded from healthy donors. The ASC product contains 22 million ASCs/ml.

  • Cryostor CS10Drug

    CryoStor® CS10 freeze medium

What is being measured

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

  1. Ocular Surface Disease Index (OSDI)

    The OSDI is a valid and reliable instrument for measuring dry eye disease severity

    Measured: 4 months after treatment

Secondary outcomes (6)
  1. Non-invasive keratography tear break-up time (NIKBUT)

    As measured with the Keratograph 5M (Oculus™)

    Measured: 4 months after treatment

  2. Tear meniscus height (TMH)

    As measured with the Keratograph 5M (Oculus™)

    Measured: 4 months after treatment

  3. Schirmer's I test

    Change in tear production as evaluated with the Schirmer's I test

    Measured: 4 months after treatment

  4. Tear osmolarity

    Change in tear osmolarity measured with TearLab™

    Measured: 4 months after treatment

  5. Oxford scale

    Change in staining of the ocular surface (grade 0-5 with 0 being absent corneal staining and 5 being severe corneal staining)

    Measured: 4 months after treatment

  6. HLA anti-bodies

    Development of anti-human leucocyte antigen (HLA) anti-bodies evaluated with Luminex HLA anti-body screening

    Development of anti-HLA anti-bodies evaluated with Luminex HLA anti-body screening

    Development of donor-specific HLA-antibodies

    Measured: 12 months after treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ASCs and Cryostor CS10 in people with Keratoconjunctivitis Sicca, in Sjogren's Syndrome, run by Copenhagen University Hospital, Rigshospitalet at 1 site in Denmark.

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 4 inclusion and 7 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 8 Mar 2023. 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 Denmark. 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. Some participants in this study may receive a placebo. 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?

Ocular Surface Disease Index (OSDI) (time frame: 4 months after treatment). 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 NCT04615455, 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 8 Mar 2023.
