| Study type | Participant information sheet |
| Scientific title | A study of thiotepa, ifosphamide, etoposide and rituximab for the treatment of relapsed or refractory primary central nervous system lymphoma |
| Study acronym | TIER |
| Study objectives | The phase I dose finding component is a 3+3 cohort design which will recruit up to 18 patients in order to find the MTD of thiotepa in combination with ifosphamide, etoposide and rituximab (TIER). All patients recruited into phase I at the MTD will also contribute towards phase II. The phase II study is based on an A'Hern’s design to assess the activity of thiotepa in combination with ifosphamide, etoposide and rituximab (TIER). 28 patients will be recruited in total in phase II (including some patients from phase I). |
| Ethics approval(s) | 14/LO/1568; First MREC approval date |

| Primary outcome measure(s) |
MTD of thiotepa in combination with ifosphamide, etoposide and rituximab (TIER) |
| Key secondary outcome measure(s) |
