PHAR investigators, in partnership with Genentech, Inc., conducted an insurance claims analysis to examine how real-world treatment of chronic spontaneous urticaria (CSU) among commercially insured and Medicaid patients aligns with current global treatment guidelines. PHAR’s Sheila Reddy, PhD, MSc, RPh, Eunice Chang, PhD, and Marian Tarbox, MPP found that adherence to treatment-based guidelines for CSU was generally low in both populations of patients, and described treatment patterns at the annual meeting of the American Academy of Allergy, Asthma & Immunology. The poster can be viewed here, and the abstract was published in the February supplement issue of the Journal of Allergy and Clinical Immunology.
