Brief Summary:
The study investigates, whether the patient group with intermediate-risk early breast cancer benefits from treatment with ribociclib in combination with endocrine therapy compared to standard-of-care chemotherapy (followed by adjuvant endocrine therapy).

Condition or disease Intervention/treatment Phase
Breast Cancer Female Drug: Ribociclib 200Mg Oral Tablet Phase 3

Detailed Description:

The WSG ADAPT trial program is one of the first new generation trials addressing the issue of individualization of (neo)-adjuvant decision-making in early breast cancer (EBC) in a subtype-specific manner. The first WSG ADAPT umbrella trial (NCT01779206) aimed to establish early predictive molecular surrogate markers for response after a short 3-week induction treatment.

The goals of the WSG ADAPT trial program - early response assessment and subtype-specific therapy tailoring to those patients who are most likely to benefit - have contributed to the very positive national and international feedback to the ADAPT concept as a whole.

The aim of this ADAPTcycle phase-III-trial is to investigate whether the intermediate-risk patient group identified during the screening phase derives additional benefit from treatment with ribociclib in combination with ET compared to chemotherapy (followed by adjuvant ET).

    6. Patient has HER2-negative breast cancer defined as

  • a negative in-situ hybridization test or an IHC status of 0, 1+, or 2+,
  • if IHC is 2+, a negative in-situ hybridization (FISH, CISH, or SISH) test is required (based on the most recently analyzed tissue sample and all tested by a local laboratory).

    7. Local therapy of breast cancer (if adjuvant treatment or planned if neoadjuvant treatment) according to current guidelines.

Note: This may include radiotherapy of breast cancer.

B. Prior to RANDOMIZATION in the study 8. No evidence of distant metastasis (confirmed prior to randomization by, preferentially, CT thorax / abdomen, X-ray chest, ultrasound liver, bone scan, or PET-CT).

9. Patient has available tumor tissue from diagnostic biopsy. 10. Patient is classified as intermediate risk according to the ADAPT intermediate-risk definition (i) (as follows), or (only in case of missing Oncotype DX or Ki-67 response data), according to the clinical intermediate-risk definition (ii) (as follows).

(i). ADAPT intermediate-risk definition: Patient meets one of the following criteria:

  • c/pN0, RS ≤ 25 with luminal-B-like (Ki-67 ≥20% or G3) or c/pT2-4 without endocrine response (post-endocrine Ki-67 > 10 %)
