Brief Summary
This is a prospective validation study, multicenter, open-label, single-arm study, evaluating the concordance between capillary microsampling (using the VAMS Mitra device) and venous sampling in patients undergoing CDK4/6 therapy.

Outcome Measures
Primary Outcomes (1)
Measurement of the concordance between the drug concentrations obtained from capillary and venous sampling.
The primary objective of the study is therefore to validate the reliability of capillary sampling (using the VAMS Mitra device) as an alternative to venous sampling for TDM of CDK4/6 inhibitors (ribociclib, abemaciclib, or palbociclib) in breast cancer patients. The primary endpoint will be the concordance between drug concentrations obtained from venous and capillary samples, assessed through Bland-Altman analysis.
Day 1
Secondary Outcomes (2)
Intra-patient's variability of the measurements from microsamplings
Day 1
Acceptability of the device, as assessed by a patient satisfaction questionnaire.
Day 1
Study Arms (1)
Blood samples collection in breast cancer in patients receiving CDK4/6 inhibitors
EXPERIMENTALFive blood samples will be collected at a single time point during treatment, in accordance with the routine TDM schedule (the treatment duration will remain as per the prescribed CDK4/6 regimen). The patients will also complete an acceptability Questionnaire following the samplings.
Interventions
Five blood samples will be collected at a single time point during treatment, in accordance with the routine TDM schedule (the treatment duration will remain as per the prescribed CDK4/6 regimen). * 4 capillary samples (using the VAMS Mitra device) including 2 samples collected by the study nurse then 2 samples collected by the patient. * 1 venous sample (5 mL heparinized tube).
Eligibility Criteria
You may qualify if:
- Adult patients (≥ 18 years) with breast cancer.
- Patients currently receiving ribociclib, abemaciclib, or palbociclib.
- Patients capable of performing capillary sampling (with or without assistance).
- Patient information and signing of informed consent.
- Patient ability to comply with protocol requirements.
- Patients covered by a health insurance system.
You may not qualify if:
- Patients with altered mental status or psychiatric disorder that, in the opinion of the investigator, would preclude a valid patient informed consent.
- Persons deprived of their liberty or under guardianship.
