Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Minimum age
18 Years
Maximum age
No limit

Both males and females
Can healthy volunteers participate?
No
Key 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
