Recruiting
This is a study to assess the efficacy, safety, and tolerability of IMVT-1402 in adult participants with Graves' disease (GD) who are hyperthyroid despite antithyroid drug (ATD) treatment. The primary objective of this study is to evaluate the efficacy of IMVT-1402 versus placebo as assessed by T3 (total triiodothyronine \[T3\] or free triiodothyronine \[FT3\]), free thyroxine (FT4), thyroid-stimulating hormone (TSH), and ATD dose at Week 26.

A Study to Test How Well BI 770371 is Tolerated by People With Cirrhosis Caused by a Liver Disease Called MASH
Recruiting
This study is open to people with cirrhosis caused by a liver disease called MASH (metabolic dysfunction-associated steatohepatitis). The purpose of this study is to find out how well a medicine called BI 770371 is tolerated. Participants are put into 2 groups by chance. One group gets BI 770371 as an infusion into a vein and the other group gets placebo as an infusion into a vein. Placebo infusions look like BI 770371 infusions but do not contain any medicine. Participants get an infusion ever... Read More

A Study to Learn About How Well BAY3283142 Works and Its Safety in Participants With Chronic Kidney Disease
Recruiting
Researchers are looking for a better way to treat people who have chronic kidney disease (CKD), CKD is a condition in which the kidneys' ability to work properly gradually decreases over time. A common sign of decreasing kidney function is the body losing too much of a protein called albumin in the urine. This condition is known as albuminuria. This can lead to a faster decline in kidney function. People who have high blood pressure and diabetes are more likely to have CKD and are at a higher ri... Read More
