Safety and blood-level testing of an oral fixed-dose combo of ceftibuten and ledaborbactam etzadroxil
This will test the safety and how the body processes an oral fixed-dose combination of ceftibuten and ledaborbactam etzadroxil in healthy adults aged 18–55.

Zanzalintinib with immune checkpoint drugs for advanced solid tumors
This trial will test whether zanzalintinib alone or combined with immune drugs (nivolumab, with or without ipilimumab or relatlimab) is safe and helps people with advanced or metastatic solid tumors such as renal cell, prostate, urothelial, and liver cancers.
