Study Endpoints

Primary Endpoints

Number of Participants with Adverse Events
3 - 9 weeks

safety of a dual HER2-targeted therapy with Herceptin® (trastuzumab), Perjeta® (pertuzumab) and Kisqali® (riobciclib) plus endocrine therapy as compared to a dual HER2-targeted therapy with Herceptin® (trastuzumab) and Perjeta® (pertuzumab) plus chemotherapy (followed by endocrine therapy plus ribociclib in combination with trastuzumab and pertuzumab as maintenance therapy) by the proportion of patients experiencing any adverse event (as defined by the modified adverse event score)

Maximum tolerated dose (MTD) (Phase Ib)
During the first cycle of treatment (1 cycle = 28 days)

Defined as the highest dose level that does not lead to unacceptable toxicity in two or more patients in a dosing level.

Pathologic complete response (pCR) (Phase II)
Up to 30 days after last treatment dose

Defined as no invasive tumor in the breast or lymph nodes at the time of surgery. Response evaluable participants are defined as participants who are randomized and have receive at least one cycle of protocol therapy. The pCR rate is defined as percentage of randomized patients with a pCR in each of the treatment arms.The estimated pCR rate (and 95% confidence interval \[CIs\]) will be calculated for each experimental arm and compared to the corresponding control arm using the Cochran-Mantel-Haenszel x\^2 test, with a two-sided significance level of 5%. Absolute differences in pCR rate between study arms will be calculated, along with 95% exact confidence intervals. This will be stratified according to hormone receptor (HR) status Multivariate logistic regression will be used to control for important baseline characteristics and odds ratios with corresponding CIs will be calculated.
