ClinConnect Summary

The SPYRAL AFFIRM study is looking at a new treatment for people with high blood pressure (hypertension) who have not been able to control it with medication alone. The trial will test a device called the Symplicity Spyral system, which is designed to help lower blood pressure by targeting the nerves around the kidneys. This study aims to find out how safe and effective this treatment is over the long term.

To participate, you need to have high blood pressure, with specific measurements indicating that it’s not well controlled. For example, your systolic blood pressure (the top number) needs to be at least 140 mmHg. However, there are some conditions that would exclude you from joining, such as having certain kidney issues or other serious health problems. If you join the study, you will receive the treatment and be monitored to see how your blood pressure responds over time. This trial is currently recruiting participants aged 65 to 74, and both men and women can take part.
