Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To compare the impact of Pravastatin on the occurrence of grade =2 breast fibrosis in a selected breast cancer patient population considered at high risk of severe breast fibrosis occurrence (identified by the NovaGray RILA Breast® test) vs placebo.;Secondary Objective: •To evaluate the impact of this personalized radiotherapy on: - Acute and late toxicities - Safety - Local recurrence - Relapse free survival (RFS) - Breast fibrosis-free survival (BF-FS) - Breast fibrosis-relapse-free survival (BF-RFS) - Overall survival (OS) - Patients’ quality of life (HRQOL) - Cosmetic Outcomes •Evaluate the NovaGray RILA Breast® test performance •Evaluate the feasibility of a new production technique for NovaGray RILA Breast® test •Evaluate the NovaGray RILA Breast® test stability at 12 months ;Primary end point(s): breast fibrosis-free survival;Timepoint(s) of evaluation of this end point: the time from the date of randomization to the date of the first documented grade =2 breast fibrosis | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1.Incidence of acute (within 3 months during and after radiotherapy) and late side effects 2.Pravastatin tolerance 3.Local recurrence rate 4.Relapse-free survival (RFS) rates 5.Breast fibrosis-free survival (BF-FS) rates 6.Breast fibrosis-relapse-free survival (BF-RFS) rates 7. Overall survival (OS) rates 8.Quality of life 9.Cosmetic outcomes 10.Identification of clinico-biologicals parameters to improve the NovaGray RILA Breast® test performance 11.1 x 4 ml blood sample at baseline for the evaluation of the feasibility of a new production technique for NovaGray RILA Breast® test 12.1 x 4 ml blood sample at 12 months for the evaluation of NovaGray RILA Breast® test stability;Timepoint(s) of evaluation of this end point: 1.side effects is assessed and graded according to the NCI-CTCAE v5.0 scale.The most severe grade observed during the period per patient will be reported. 2.Tolerance is assessed and graded according to the NCI-CTCAE v5.0 scale 3.Local recurrence rate from the date of randomization to 1, 2, 3, 5 and 10 years 4, 5, 6.the rates are defined as the time from the date of randomization to the date of the first relapse 7. is defined as the time from the date of randomization to the date of death 8. is assessed from the date of randomization to follow-up 5 years 9.is assessed from the date of randomization to 2 years after the end of treatment 10. is defined from the date of randomization to the end of study 11.is assessed at Baseline 12.is assessed at 12 month after randomisation | — |
