Condition/Disease

Advanced or Metastatic Breast Cancer

Objectives

The aim of this trial was to evaluate whether PF-07220060 in combination with fulvestrant, relative to the investigator's choice of therapy (ICT) (i.e., fulvestrant alone, or everolimus in combination with exemestane), could improve clinical outcomes in participants with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or metastatic breast cancer (mBC) whose disease had worsened after prior treatment with cyclin-dependent kinase (CDK) 4/6 inhibitors.

Endpoints

The trial administrator determines PFS as the time elapsed from the randomization date to the date of first recorded disease progression. The determination is based on the trial administrator's assessment according to the Response Evaluation Criteria in Solid Tumors (RECIST) v.l., or death from any cause without disease progression (PD), whichever occurs first.

Inclution Criteria

Inclusion Criteria:

Histological confirmation of breast cancer with evidence of locally advanced or metastatic disease, which is not amenable to surgical resection or radiation therapy with curative intent.
Documented estrogen receptor (ER) and/or progesterone receptor (PR)- positive tumor
Documented HER2-negative tumor
Able to provide a sufficient amount of representative formalin fixed, paraffin embedded (FFPE) tumor tissue specimen.
Must have received CDK4/6i plus NSAI defined per study protocol. There must be documented PD during or after CDK4/6i treatment.
Measurable disease or non-measurable bone only disease as defined by RECIST version 1.1.
Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) ≤2.

Exclusion Criteria

Exclusion Criteria:

Any medical or psychiatric condition that may increase the risk of study participation or make the participant inappropriate for the study.

Prior treatment with any of the following:
Everolimus or investigational anti-cancer agents in any setting
Prior chemotherapy in the advanced setting
Radiation within 2 weeks of randomization
Current use or anticipated need for any prohibited food, supplements or concomitant medication(s) (ie, other anti-cancer therapies, other endocrine therapies, growth factors, chronic systemic corticosteroids, strong cytochrome P450 3A4/5 [CYP3A4/5] or uridine 5' diphosphate-glucuronosyltransferase 2B7 [UGT2B7] inhibitors and inducers, direct oral anticoagulants, proton pump inhibitors).
