Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Other: Advise letrozole, treatment choice free.
All patients initially start with two weeks of letrozole treatment.
Patients with a Ki67 of <1% in the biopsy taken after those two weeks of treatment are advised to stay on letrozole treatment until surgery.
However, treatment choice is free.
|
Letrozole 2.5 mg daily.
|
Active Comparator: Chemotherapy
All patients initially start with two weeks of letrozole treatment.
Patients with a Ki67 of ≥1% in the biopsy taken after those two weeks of treatment are randomized between chemotherapy (standard AC-T chemotherapy) or ribociclib plus letrozole (ribociclib 600 mg/day (days 1-21, q4 weeks) plus letrozole 2.5 mg daily (days 1-28, q4 weeks)).
|
Dose dense AC-T chemotherapy: consisting of 4 cycles of AC (doxorubicin and cyclophosphamide at a dose of 60 and 600 mg/m² as an i.v.
bolus, respectively) 2-weekly, plus G-CSF (6 mg once per cycle) 24-48 hr after chemotherapy, followed by cycles of T (4 cycles docetaxel 100 mg/m² 3-weekly or 12 cycles paclitaxel 80 mg/m2 weekly).
|
Experimental: Ribociclib plus letrozole
All patients initially start with two weeks of letrozole treatment.
Patients with a Ki67 of ≥1% in the biopsy taken after those two weeks of treatment are randomized between chemotherapy (standard AC-T chemotherapy) or ribociclib plus letrozole (ribociclib 600 mg/day (days 1-21, q4 weeks) plus letrozole 2.5 mg daily (days 1-28, q4 weeks)).
|
Ribociclib 600 mg/day (days 1-21, q4 weeks) plus letrozole 2.5 mg daily (days 1-28, q4 weeks).
|
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Difference in complete cell cycle arrest (CCCA; defined as Ki67 IHC <1%) between ribociclib plus letrozole and chemotherapy in the surgical specimen.
Time Frame: CCCA will be determined in the surgical specimen, which is around 7 months after start of initial letrozole treatment.
|
Determine if ribociclib plus letrozole gives a ≥100% improvement in CCCA as compared to chemotherapy in the surgical specimen.
|
CCCA will be determined in the surgical specimen, which is around 7 months after start of initial letrozole treatment.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Correlation between Ki67 IHC scored manually, IHC scored automatically (Vectra ® 3) and Ki67 mRNA.
Time Frame: Ki67 measurements will be done in the primary core biopsy (baseline), two weeks biopsy (done after two weeks of initial letrozole treatment) and the surgical specimen (which is around 7 months after start of initial letrozole treatment).
|
The correlation between the different Ki67 measurements will be determined in the primary core biopsy, two weeks biopsy and surgical specimen.
|
Ki67 measurements will be done in the primary core biopsy (baseline), two weeks biopsy (done after two weeks of initial letrozole treatment) and the surgical specimen (which is around 7 months after start of initial letrozole treatment).
|
Correlation between ER pathway activity at baseline, after two weeks letrozole and at surgery and clinical outcome.
Time Frame: ER pathway activity will measured in the primary core biopsy (baseline), two weeks biopsy (done after two weeks of initial letrozole treatment) and the surgical specimen (which is around 7 months after start of initial letrozole treatment).
|
The ER pathway activity will be determined in the primary core biopsy, two weeks biopsy and surgical specimen and then correlated with clinical outcome. Activity will be determined using a Bayesian network model of the ER transcriptional program, which interprets the pathway target genes' mRNA levels (from Affymetrix HG-U133Plus2.0 arrays) and infers a probability that the ER pathway is active in a certain sample. |
