Brief Summary: PATRICIA is a phase II open-label multicentre Simons two-stage-design study of the combination of palbociclib plus trastuzumab with or without letrozole in post-menopausal patients with HER2-positive locally advanced or metastatic breast cancer MBC who have received chemotherapy and treatment with trastuzumab for their metastatic disease Cohorts A B1 and B2 based on their HR status and treatment allocation were planned

Cohort A included patients with hormone receptor-negative HER2 positive breast cancer who received trastuzumab palbociclib

Cohort B1 included patients with hormone receptor-positive HER2 positive breast cancer who received trastuzumab palbociclib

Cohort B2 included patients with hormone receptor-positive HER2 positive breast cancer who received trastuzumab palbociclib letrozole

The aim of the PATRICIA study is to test the hypothesis that the addition of Palbociclib to standard therapy is well tolerated and can provide a benefit in progression-free survival

Based on interim results from this trial that support the benefit of CDK4 6 inhibition in luminal disease two additional cohorts will be included
Detailed Description: After the amendment of PATRICIA study two additional cohorts will be included

Cohort C1 will include patients with OR HER2 positive Luminal intrinsic subtype determined by PAM50 who will receive trastuzumab palbociclib endocrine therapy ET
Cohort C2 will include patients with OR HER2 positive Luminal intrinsic subtype determined by PAM50 who will receive treatment of physicians choice

When the recruitment of those cohorts C begins the recruitment in cohorts A and B will be closed

For cohorts C an adaptive design will be applied to compare arms of treatment in patients with Luminal subtype locally advanced or metastatic breast cancer MBC

All patients in those cohorts will have histologically- confirmed HRHER2-positive and PAM50-confirmed Luminal intrinsic subtype breast adenocarcinoma and must have received at least 1 previous line of sistemic treatment for locally advanced disease or MBC which must have included trastuzumab andor anti-HER2 Antibody-Drug conjugate

Stratification factors will include number of previous regimens for advanced breast cancer one and two vs three or more and presence of visceral disease yes vs no

Treatment in all cohorts will be administered until progression unacceptable toxicity patient consent withdrawal or death A total of 102 patients will be included The inclusion period will be divided in two phases During phase I it is planned to include 45 patients in 24 months considering early stopping rule according to SF rate During phase II the trial will continue until the final evaluable number of 102 randomizations are included
