Effect of HSD3B1 (1245C) Gene Mutation on Treatment of Stage I-III Breast Cancer
NCT05183828
Recruiting
This stage IV trial examines how a mutation in HSD3B1 (1245C) gene affects treatment of stage I-III breast cancer. This trial may help researchers determine if mutations in HSD3B1 decreases the efficacy of aromatase inhibitor therapy such as letrozole. Letrozole may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Nasal Steroids, Irrigation, Oral Antibiotics, and Subgroup Targeting for Effective Management of Sinusitis
NCT06076304
Recruiting
Sinus infections are sometimes treated with oral antibiotics or nasal steroid sprays, while some patients get better on their own. Some patients may wait a few days or use common over-the-counter remedies to see if their symptoms improve without further treatment. Sometimes this is enough to help patients wait a few days to see if their infection clears up without needing to use antibiotics or nasal steroid sprays. The overall goal of this clinical trial to see which specific groups of patients... Read More
