New drug combo for advanced colorectal cancer
This trial tests a new combination of targeted therapies for people with advanced colorectal cancer that has a certain genetic pattern (non-MSI-H, no BRAF V600E mutation). It aims to see if the combination can shrink tumors or slow the cancer's growth.

Study of PLX-61639 for advanced SMARCA4-mutant solid tumors
This trial is testing a new drug called PLX-61639 for people with advanced solid tumors that have a specific SMARCA4 gene change. The drug aims to stop cancer growth by targeting the cells that lack this gene.
Scottsdale, ArizonaAges 18 years+ - NCT07285785RecruitingPhase 4
Rifaximin for children with acute diarrhea
This study tests whether a medicine called rifaximin, taken along with oral rehydration solution, helps children aged 6 to 11 recover faster from acute (short-lasting) diarrhea that is likely caused by a bacterial infection. The study compares rifaximin plus oral rehydration versus oral rehydration alone.
