Graves Disease
Conditions
Brief summary
The goal of this clinical trial is to compare two methods of guiding methimazole therapy in patients with Graves' disease: methimazole dose adjustments based on a new semi-automated computer-guided treatment (based on a mathematical model) or based on the treating physician's decision (i.e. usual care). The main question it aims to answer is whether semi-automated computer-guided treatment is not inferior to usual care in terms of safety, the time it takes to achieve euthyroidism and the methimazole dose required.

Exclusion criteria
* Previous treatment with radioactive iodine * Ongoing antithyroid treatment for more than one month * Pregnancy * Treatment with propylthiouracil
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The primary aim is to compare semi-automated computer-guided treatment with usual care in terms of their performance indices | 18 months | The performance index is the deviation from the desired free thyroxine (fT4) value |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Comparison in terms of cumulative methimazole dosing | 18 months | Comparison in terms of cumulative methimazole dosing |
| Comparison based on free thyroxine (fT4) target range | 18 months | Comparison based on free thyroxine (fT4) target range |
