- Target Recruitment
- 4100
- Participants who received adjuvant chemotherapy or no chemotherapy
must have the following:
– No pathological involved nodes (pN0) and primary tumor larger than
1 cm, and must fulfill at least one of the features: Grade 3 or Ki67=20%
or Oncotype DX =26 (if available) or High-Risk MammaPrint (if
available)
or
– Pathological node-positive disease (microscopic and/or macroscopic
tumor involvement, =pN1) and will be stratified in medium or high risk
based on additional biological criteria: Grade, Ki67, Oncotype DX or
MammaPrint
-Participants who received neoadjuvant chemotherapy must have
residual disease in lymph nodes (=ypN1) after neoadjuvant
chemotherapy.
- Participants with any pT primary tumor and pN2 or any pT primary
tumor and pN3 or pT4 primary tumor and any pN.
- Participants who have documented ER+ (positive) tumor by
immunohistochemistry, as assessed locally on a primary disease
specimen and defined as = 1% of tumor cells stained positive according
to the ASCO/College of American Pathologists (CAP) guidelines or
European Society of Medical Oncology (ESMO) guidelines or any national
guidelines with criteria conforming to ASCO/CAP or ESMO guidelines.
- Participants must have undergone definitive surgery of their primary
breast tumor(s) and axillary lymph nodes (ALND and/or SLNB).
- Participants who received adjuvant chemotherapy must have
completed adjuvant chemotherapy prior to randomization. Participants
may also have received neoadjuvant chemotherapy. A washout period of
at least 21 days is required between last adjuvant chemotherapy dose
and randomization.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 3100

F.1.3.1 Number of subjects for this age range 1000
- Participants who have been diagnosed with Stage IV breast cancer
- Participants who are pregnant or breastfeeding, or intending to become
pregnant during the study or within 10 days after the final dose of
giredestrant, or within the time period specified per local prescribing
guidelines after the final dose of TPC.
- Participants who have received treatment with investigational therapy
within 28 days prior to initiation of study treatment or are currently
enrolled in any other type of medical research that is scientifically or
medically incompatible with this study
- Participants receiving or planning to receive a CDK4/6i as
(neo)adjuvant therapy. Short course of up to 12 weeks of neoadjuvant
or adjuvant treatment with CDK4/6 inhibitor therapy prior to
randomization is allowed.
- Participants who have active cardiac disease or history of cardiac
dysfunction
- Participants who have a history of any prior (ipsilateral and/or
contralateral) invasive breast cancer or ductal carcinoma in situ (DCIS).
Participants with a history of contralateral DCIS treated by only local
regional therapy at any time may be eligible.
