简要总结
This is a limited open-label study being performed at two centers in the Netherlands. All participants will receive the same treatment, and both the patients and doctors will know what that treatment is. The goal is to see how safe and effective the PRIMUS system is for preventing Chronic Cluster Headaches (CCH) in people who haven't responded well to the drug verapamil. The study will also look at the patients' experience using the system.
详细描述
During a Cluster Headache attack, the brain area called the hypothalamus may not do its usual job of blocking pain signals, which can make the pain worse. Stimulating the occipital nerves (at the back of the head) may help return brain activity in certain areas-like the hypothalamus, midbrain, and lower brainstem-back to normal. This could help reduce the brain's sensitivity to pain over time.
Stimulating another nerve group, called the V1 branch of the Trigeminal nerves (around the forehead and eye), can also help by interrupting pain signals and possibly stopping an attack or making it less severe and less frequent.
When both nerve areas-the Trigeminal and Occipital nerves-are stimulated together, it may have a stronger effect on reducing pain and how often headaches happen. Some early reports in a few patients have shown promising results with this combined treatment.
The PRIMUS system is a small device that can be implanted under the skin. It was designed to target both the Trigeminal and Occipital nerves at the same time, with a focus on treating severe head and face pain. It may offer relief for people with chronic cluster headaches who haven't been helped by medication.

Safety Assessment
时间窗: 12 weeks
The primary safety assessment is the incidence of serious procedure and/or device-related adverse events in all subjects at the 12 week visit and at the end of the study. All adverse clinical events will be collected, coded and reported, throughout the duration of the study according to the definitions of ISO 14155:2020. Device and procedure-related adverse events will be distinguished from stimulation-related adverse events. All device deficiencies, as defined by ISO 14155:2020, will be documented and reported throughout the duration of the study.
