Scientists dig into why some people get severe valley fever
NCT ID NCT02190266
First seen Jun 24, 2026 · Last updated Jul 29, 2026 · Updated 8 times
Summary
This study looks at people with severe or hard-to-treat Valley Fever, a lung infection caused by a fungus found in the southwestern U.S. Researchers want to understand why some people get seriously ill by studying their immune systems and genetics. Up to 400 participants will give blood, urine, and sputum samples and have yearly check-ups. The goal is to learn more about the disease, not to test a new treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this research could point toward new ways to treat or prevent severe Valley Fever by identifying immune system weaknesses.
- What could go wrong
- This is an observational study, not a treatment trial. It may not lead directly to new therapies, and results could take years to apply.

* INCLUSION CRITERIA: To be eligible for this study, potential participants must meet the following criteria: 1. Age \>= 2 years old. a. Enrollment of pediatric patients who are acutely ill or likely to become acutely ill will be deferred until a time when they are considered medically stable by the PI. 2. Have a positive Coccidioides antigen load or culture proven (a) refractory pulmonary coccidioidomycosis or (b) disseminated coccidioidomycosis. 1. Refractory pulmonary coccidioidomycosis must have occurred for at least 6 months and includes progressive pulmonary involvement without significant pulmonary cavitation. 2. Disseminated CM is coccidioidomycosis infection in one or more regions outside of the chest. 3. Agree to undergo genetic testing. 4. Allow their samples to be stored for future research. EXCLUSION CRITERIA: 1. HIV infection 2. Currently taking more than 20 mg/day of prednisone or undergoing active immunosuppressive therapy in the opinion of the investigator 3. Any medical, psychiatric, social condition, occupational reason or other responsibility that, in the judgment of the investigator, is a contraindication to protocol participation or impairs a volunteer s ability to give informed consent.
