ClinConnect Summary
This clinical trial is examining a condition called Giant Cell Arteritis (GCA), which affects the blood vessels, particularly those in the head and neck. The main goal of the study is to find out if a phenomenon known as Clonal Hematopoiesis of Indeterminate Potential (CHIP) is related to how GCA develops and how patients respond to treatment. Researchers will look at blood samples from patients who are suspected of having GCA to see if CHIP is present and how it might influence the disease's symptoms and progression.
To participate in this trial, patients must be between the ages of 65 and 74 and have symptoms suggesting active GCA, as well as be able to provide consent for the study. They should also be able to undergo a temporal artery biopsy, a quick procedure to help confirm the diagnosis, within three hours of joining the study. Patients with certain infections, active cancers, or those on specific medications will not be eligible. Participants in this trial can expect thorough assessments, including blood tests and biopsies, to help researchers better understand the connection between CHIP and GCA. This study is not yet recruiting participants, but it aims to gather important information that could improve treatments for patients with GCA in the future.
