MedicalResearch.com Interview with: Joanne L. Blum, MD, PhD, FACP Texas Oncology and Director Hereditary Cancer Risk Program Baylor University Medical Center MedicalResearch.com: What is the background for this study? Would you briefly describe the POLARIS study? Response: POLARIS is an ongoing prospective, real-world, non-interventional study in patients with HR+/HER2-ABC receiving palboiclib plus endocrine therapy with a targeted enrollment of 1500 patients at 110 sites in the United States and Canada.  MedicalResearch.com: What are the main findings?

• Because of the COVID-19 pandemic, approximately one third of the study sites experienced an impact on their responsiveness to correspondence, timely data entry, and subject management.
• The geographic location or type (e.g., academic or community) of study site appears associated with whether the site was impacted by COVID-19.
• Other study site characteristics were generally similar between sites that reported an impact of COVID-19 and those that were not impacted.
• Because of inherent limitations of survey studies, these findings must be interpreted with caution.
