Spots Global Cancer Trial Database for Study Of Real-World Evidence In Patients Treated With Palbociclib During a 2.5 Years Follow-Up Period

Study Description

Brief Summary: PALBO is a Non-Interventional, National Study Of Real-World Evidence In Estrogen Receptor Positive, Her2 Negative Metastatic Breast Cancer Patients Treated With Palbociclib During A 2.5 Years Follow-Up Period. The primary objective is to identify pathological and clinical features of MBC that is associated with Palbociclib's best efficacy, measured by response rate (overall response rate, duration of response and best clinical response), progression free survival and OS. Safety of Palbociclib will also be evaluated.

Detailed Description: Metastatic breast cancer (MBC) is the most advanced stage of breast cancer, where the disease has spread to distant sites beyond the axillary lymph nodes. At European level, MBC occurs in up to 20-30 percent of women diagnosed with early-stage breast cancer. At regional level, there are variations in newly diagnosed patients who present with metastatic disease. In high income countries fewer than 8% of patients are initially diagnosed with MBC, while the highest burden of MBC is carried by low and middle-income countries where up to 60% are initially diagnosed with MBC. Currently, the median overall survival for patients with MBC is approximately 2 to 3 years in developed countries, but lower in developing countries. In Romania, 8900 new cases of BC are diagnosed every year, with 80% being diagnosed in an advance stage of the disease (II, III, IV). Furthermore, after initial BC treatment, approximately 50% will develop MBC. Cyclin-dependent kinase (CDK) 4/6 inhibitors (Palbociclib, ribociclib and abemaciclib) are now standard of care for the treatment of advanced hormone receptor positive (HR+) and HER2 negative (HER2-) breast cancer. On 09 November 2016, the EC has approved IBRANCE® (Palbociclib) as the first CDK 4/6 inhibitor, to be used in combination with letrozol as first-line or in combination with fulvestrant in women who have received prior endocrine therapy, based on the results of PALOMA-1, PALOMA-2 and PALOMA-3 study results. Other phase III randomized trials have been reported and confirmed the efficacy of CDK4/6 inhibition in both first-line and endocrine resistant settings. Palbociclib®, an orally active pyridopyrimidine, is a potent and highly selective reversible inhibitor of CDK 4 and CDK6. The compound prevents cellular DNA synthesis by prohibiting progression of the cell cycle from G1 into the S phase. Specifically, Palbociclib inhibits CDK4/6-catalyzed phosphorylation of the retinoblastoma protein (Rb), which is required for cell division. Palbociclib® has selectivity for CDK4/6, with little or no activity against a large panel of 274 other protein kinases including other CDKs and a wide variety of tyrosine and serine/threonine kinases. An approximate number of 650 patients will be included in the present study which will take place on national level in 6 sites in Romania.
