Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

- Clinical diagnosis of TED based on CAS

Exclusion Criteria:

  • Decrease in CAS or proptosis of >= 2 points or >= 2 mm, respectively, in the study eye between Screening and Study Baseline (Day 1)
  • Requiring immediate surgical ophthalmological intervention or planning corrective surgery or irradiation during the course of the study, in the judgment of the investigator
  • Identified pre-existing ophthalmic disease that, in the judgment of the investigator, would preclude study participation or complicate interpretation of study results, including corneal decompensation unresponsive to medical management and including ophthalmic diseases that will likely require prohibited therapy during the study
  • Any serious medical condition or abnormality in clinical laboratory tests that, in the investigator's judgment, precludes an individual's safe participation in and completion of the study
  • Pregnant or breastfeeding, or intention of becoming pregnant during the study or within 3 months after the final dose of satralizumab

Staining assessment will be based on the intensity of fluorescein staining, ranging from Grade 0 to V for each panel (0=absent; I=minimal; II=mild; III=moderate; IV= marked; and V=severe). Higher grade indicates worse disease index. The observer compares the overall appearance of the participant's corneal staining with the reference figure in the protocol. The observer selects the appropriate grade that best represents the state of corneal staining. The staining score were recorded for the exposed interpalpebral cornea and conjunctiva.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
