General information about the trial
|
|||
Main objective of the trial |
To evaluate in a feasibility study whether low uptake on FES-PET at baseline is related to non response to letrozole plus palbociclib treatment.
|
||
Protection of trial subjects |
All patients will receive an effective treatment combination. In addition to the standard control visits to the clinic, three extra visits will be performed as part of the study: for screening, for the FES-PET scan and for the early FDG-PET. The FESPET scan will induce an extra radiation burden of 6.1 mSv and the early FDG-PET 5 mSv. In the future, this study may potentially contribute to improved selection of patients for this combination treatment. This is of relevance in view of optimal treatment for individual patients, avoiding unnecessary toxicity and financial burden.

Recruitment
|

Recruitment details |
31 patients were included in the study, 29 patients completed the study. 2 patients discontinued the study prematurely: - 1 patient had dural metastases therefore no response PET/CT scan was performed - 1 patient had elevated liver enzymes, therefore a response PET/CT was performed after 1 cycle (instead of after 2 cycles), progressive disease | ||||||

Amendment |

19 Jun 2017 |
1. Moving the FDG PET scan from 8 weeks to 2 weeks after the start of treatment.
2. Expand the number of patients from n=15 to n=30 for the implementation of point 1. Expanding the number of patients also enables further refinement of the FES-PET analysis: namely by adding a per-patient analysis with regard to response, in addition to the per-lesion analysis (the primary endpoint). |
