Therapeutic Proteins clinical trials at University of California Health

This is an observational, clinic-based, single center study of 120 subjects. Participants will be comprised of patients seen in the outpatient faculty practice in ambulatory care at the UCSF Parnassus campus. Study investigators will enroll 20 healthy participants with no history of lung disease, 50 asthmatics who are newly prescribed therapeutic proteins for their asthma, and 50 asthmatics already being treated with therapeutic proteins for their asthma. Participants will be seen at 1 to 3 visits and provide blood samples at each visit.
