RESUMO
The prospective, non-interventional PERFORM study describes and analyzes the effectiveness of palbociclib in combination with endocrine therapy (aromatase inhibitor or fulvestrant) as first-line treatment for patients with locally advanced or metastatic HR+/HER2- breast cancer in the real-world setting in Germany and Austria. PERFORM will reflect current patient characteristics and routine treatment patterns including treatment sequences and time to subsequent (chemo)therapy. Besides, second-line treatment effectiveness and patient-relevant end points such as longitudinal patient-reported outcome measurements beyond disease progression will be analyzed. Accounting for the heterogenous real-world patient population, data on clinicopathologic subgroups underrepresented in clinical trials such as elderly or male will be analyzed. Taken together, PERFORM will close knowledge gaps from clinical trials in real world.
Palbociclib in combination with endocrine therapy is the standard first-line treatment for patients with advanced HR+/HER2- breast cancer. Data from clinical trials have shown high response rates and good tolerability. To support these data and close potential knowledge gaps, we conduct the multicenter, observational PERFORM study to evaluate the effectiveness and patient-reported outcomes in patients with advanced HR+/HER2- breast cancer treated with endocrine-based palbociclib therapy in routine clinical practice in Germany. Clinical Trial Registration: NCT04767594 (ClinicalTrials.gov) Sponsor: Pfizer Pharma GmbH, Linkstraße 10, D-10785 Berlin, Germany.
