Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary objective is to assess the safety of thioguaninein maternally exposed offspring. Efficacy variables will be the number and aspect of birth defects (minor and major) and rate of pre-term births, low-birth weights, (spontaneous) abortions and neonatal morbidity. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary efficacy variables will be the number of complications during pregnancy and delivery, and the course after delivery. Furthermore, signs of myelosuppression or hepatotoxicity in the neonate and thiopurine metabolite measurements in the neonate (if applicable) will be assessed. | — |
