Main objective

Scope: Safety, Efficacy

The overall aim of the BLOOD-dose platform trial is to identify the optimal treatment intensity for patients with haematological diseases. Given the heterogeneity of haematological diseases, objectives, endpoints and estimands will differ across domains. The objectives for each domain will be described in the Domain-Specific Appendix.
A core outcome set (COS) for haematological conditions consisting of in total 6 core outcome measurements has been established. Each domain is expected to include at least one core outcome measure as its primary endpoint, with all other core outcomes included as secondary endpoints. Thus, the main objective of a Domain-Specific Appendix could be to compare survival beween the interventions with the endpoint overall survival (OS), with the other 5 core outcome measures listed below as secondary objectives.

Secondary objectives 5

  1. To compare progression free survival (PFS) between the interventions
  2. To compare patient-reported health-related quality of life between the interventions
  3. To assess safety and tolerability of the interventions
  4. To compare the impact of treatment and disease on healthcare resource use between the interventions
  5. To compare the cost of the interventions
