E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• To assess the safety of Tamoxifen added to Venetoclax. Venetoclax will be dosed at 800 mg once daily. After 2 days of venetoclax, tamoxifen will be orally administrated in a ramp-up phase (2 days 10mg, 2 days 20mg, to a final dose of 40 once daily, see study scheme) |
• Om de veiligheid van Tamoxifen toegevoegd aan Venentoclax te beoordelen. Venetoclax wordt gedoseerd in een dosis van 800 mg eenmaal daags. Na 2 dagen venetoclax, zal tamoxifen oraal worden toegediend in een opstartfase (2 dagen 10 mg, 2 dagen 20 mg, tot een laatste dosis van 40 eenmaal daags, zie onderzoeksschema)
|
|
E.2.2 | Secondary objectives of the trial |
● To assess the efficacy of Tam added to Ven. An FDG PET /CT scan will be performed at day +28 and day +90 of the treatment ● To assess the duration of response (DOR) ● To assess the progression free survival (PFS) ● To assess the overall survival (OS)
|
● Op dag +28 en +90 van de behandeling wordt een FDG PET / CT-scan gemaakt. ● Om de responsduur (DOR) te beoordelen ● Om de progressievrije overleving (PFS) te beoordelen ● Om de algehele overleving (OS) te beoordelen |
