A clinical trial of a study medicine for people with advanced ovarian cancer

The C4161001 study is researching whether a study medicine is safe and effective in the treatment of advanced ovarian cancer.

Unfortunately, current treatment options are limited and may not work for everyone. Doctors are working to find better treatment options for people living with advanced ovarian cancer.

What are the benefits and risks?

Your cancer may get better, get worse, or stay the same. Your health will be closely monitored during the study. Participation may help people in the future by increasing our understanding of the investigational or study medicine and ovarian cancer.

If your health gets worse, your study team and your study doctor will help you decide what to do, which may mean stopping your participation in the study. Potential risks from taking part in the study may include: side effects from taking the study medicine, for example diarrhea, nausea, fatigue; risks or discomforts from study procedures such as blood tests and body scans; risk of allergic reaction to the study medicine.
