This study is looking at two ways to treat a serious yeast infection called invasive candidiasis. It includes a yeast infection in the blood, known as candidemia. People in the study first get a medicine called IV echinocandin through their veins. Later, they take either oral ibrexafungerp (a new drug) or oral fluconazole (a common drug) by mouth. The study is randomized (like flipping a coin to decide which medicine you get) and double-blind (neither the doctor nor the participant knows which medicine is given) to ensure fairness.

• Participants must be 18 or older and have a Candida yeast infection found in their blood or tissue.
• Cannot join if the infection is in certain body parts, like the heart or brain, or if they've tried other antifungal medicines that didn't work.
• The study involves multiple visits and some tests to check for side effects or other issues.

People with specific health problems, like severe liver issues or other fungal infections, should not participate. If you're interested, make sure you discuss risks and benefits with your doctor.
