Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT04653740). This is a study registration, not published results. Lead sponsor: Centre Oscar Lambret. Recruitment status: ACTIVE_NOT_RECRUITING. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 25 participants (ESTIMATED). Conditions: Advanced Breast Cancer. Interventions: PROCEDURE: specimen sample collection. Primary outcome measures: Intrapatient variation in molecular profiles at progression compared to baseline , From date of inclusion until the date of first documented progression (around 2 years); longitudinal changes in VOCs profile and exosomes according to response to treatment , From date of inclusion until the date of first documented progression, assessed up to 2 years. Brief summary: This is a monocentric cohort study, prospective and interventional with minimal risks and constraints for advanced breast cancer. The planned interventions are collection of biological samples at different times. The study will aim to do a descriptive analysis of omics profiles evolution (tumor, volatile organic components) over time, before and after disease progression under Palbociclib treatment with a clinical-biological database.
