ATX-GD-59
Immune In trials Human trials
A mix of two short peptides copied from the thyroid-stimulating hormone receptor. The idea is to retrain the immune system to tolerate that receptor, so it stops making the antibodies that drive Graves' disease, instead of suppressing immunity overall.

How it works
Two short fragments of the TSH receptor given to retrain immune tolerance. Presenting the target antigen in this form is meant to stop the immune system attacking the thyroid, rather than suppressing immunity generally.
