Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Feasibility of KD during standard treatment with RT and CT defined as successfully following the KD for 14 weeks after start of protocol treatment. So a patient is considered a failure for the primary endpoint if the KD is followed for less than 14 weeks from start of protocol treatment. | — |
Secondary
| Measure | Time frame |
|---|---|
| - Number of days on KD after start protocol treatment - Compliance to the KD reflected in adequate and stable ketosis (3-4 mmol/l). - Number of withdrawals or not reaching ketosis | — |
