Predictive Impact of Peripheral Blood Lymphocytes on clinicAL outcoMes During First-line CDK4/6 Inhibitors Plus Endocrine Therapy in Patients With Advanced Hormone REceptor-poSitive HER2-negative Breast Cancer: the Retrospective-prospective Multicenter Italian PALMARES-2 Study

PALMARES-2 is a retrospective/prospective, observational, multicenter, population-based study, aiming at providing real-world evidences on HR+/HER2- aBC patients treated with first-line CDK4/6i plus ET. The present study has the objective to collect data coming from different sources, i.e. RWD, medical images and biological samples, from patients treated with CDK4/6i as first-line of therapy for HR+/HER2- aBC. In consideration of the complexity of data collected and different objectives of the study, this master protocol foresees different sub-studies, which encompasses different methodologies for data collection, data extraction and analyses.

Detailed Description

The PALMARES-2 study aims to collect data from different sources, i.e. real-world clinical data, medical images and biological data and samples, from patients treated with CDK4/6i as first-line therapy for patients with HR+/HER2- advanced breast cancer. Due to the complexity of the data collected and the different objectives of the study, this protocol includes several sub-studies, which include different methodologies for data collection, extraction and analysis:

  • The first sub-study (RWD sub-study) will aim to collect real-world clinical data of patients who received ET+CDK4/6i in the first-line setting; the primary objective of this sub-study is to assess whether there is a difference in OS between the three CDK4/6i in the real-world population, while secondary objectives include comparisons in specific sub-groups;
  • The second sub-study (Safety sub-study) includes the collection of comorbidities, concomitant medications and toxicities of patients enrolled in the study; the primary objective of this sub-study is to evaluate the difference in severe toxicity between the three CDK4/6i in the real-world population
  • The third sub-study (medical imaging sub-study) consists of the collection of computed tomography (CT) and fluorodeoxyglucose positron emission tomography (FdG-PET) images at baseline and digitised haematoxylin-eosin (HE) slides to build a multi-omics predictive model;
  • The fourth sub-study (translational sub-study) aims to collect tumour samples from a proportion of patients enrolled in the study to perform genomics and transcriptomics analyses; information from this data source will be integrated into the model built with the previous data to further improve the performance of the previous model
  • The fifth sub-study (subsequent lines sub-study) focuses on the lines of treatment administered to patients enrolled in the study at the time of progression after first-line treatment with ET+CDK4/6i, with the aim of building predictive models of response to subsequent lines of treatment, capable of supporting oncologists' and patients' decisions in this context.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

The study involves the retrospective and prospective collection of consecutive HR+/HER2- advanced Breast Cancer patients (defined as metastatic or locally advanced not candidate for definitive curative intervention) treated with CDK4/6i in combination with endocrine therapy as first-line treatment for advanced disease in different Italian cancer centers.

Description

Inclusion Criteria:

  • Diagnosis of HR+/HER2- advanced Breast Cancer (aBC), as defined as at least 1% estrogen receptor (ER) and/or progesterone receptor (PgR) positivity at IHC. HER2 negativity is defined on the basis of an IHC score of 0, 1+, or 2+ with absence of gene amplification at in situ hybridization (ISH) analyses.
  • Have received or are candidate to receive treatment with palbociclib, ribociclib or abemaciclib in combination with endocrine therapy as first-line treatment for HR+/HER2- aBC.

Exclusion Criteria:

  • Less than 3 months of follow up from the CDK4/6i start to the date of data cut-off;
  • Have received CDK4/6i as monotherapy;
