Lower dose abiraterone without hormone shots for prostate cancer
This trial tests a lower dose of abiraterone (a pill that lowers testosterone) without the usual hormone-blocking shots for men with prostate cancer that needs hormone therapy. It is for patients at high risk or with early spread who have not had hormone therapy before.
Buenos AiresAges 18 years+ - NCT07299942Recruiting
Beta-glucan supplement for weight loss in women
This trial tests whether taking a beta-glucan supplement (a type of fiber) during a calorie- and carb-restricted diet helps with losing body weight and fat, controlling appetite, and managing hunger hormones. It is for healthy women who are overweight or obese and not following a special diet.

- How do I know if I qualify for a hormones trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a hormones trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
