Repeated nerve-block shots for chronic cluster headache
Treatments studied
Part of Brain & nervous system clinical trials.
This Phase 3 trial tests whether repeated injections can reduce attacks of chronic cluster headache. It may help people who have frequent, consistent attacks and can track them closely during the study.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 to 70 years old
- You have chronic cluster headache
- Your attacks always happen on the same side of your head
- During the 1-month lead-in period, you have at least 4 cluster headache attacks per week
- You are on a steady preventive medicine plan for more than 4 weeks and won’t change it during the study

This trial tests whether injections of botulinum toxin type A can reduce frequent, severe cluster headache attacks by targeting a facial nerve area. It’s for people whose cluster headaches have not responded well—or have caused side effects—to standard preventive treatments.
This trial tests a procedure that uses targeted pulses of energy and a special blood-platelet solution to calm a specific nerve cluster at the back of the nose, which may reduce the frequency and intensity of cluster headache attacks. It is for people whose headaches have not improved enough with standard preventive medicines.
This Phase 2 study tests whether a supervised dose of LSD (or a placebo) can reduce cluster headache attacks. It’s for people whose cluster headaches respond to oxygen, and who can safely pause certain medications and substances around the dosing day.
This study is testing a new device that uses mild electrical stimulation near the back of the head to prevent cluster headaches. It is for people with chronic cluster headaches that are hard to treat with standard medicines.
This trial tests if a device that stimulates nerves on your face and the back of your head can prevent chronic cluster headaches. It may offer a new treatment option if you have had cluster headaches for at least a year.
This Phase 2 trial tests LSD to see if it can reduce how much cluster headaches disrupt your life. You may be eligible if your cluster headaches are frequent and steady, and if you meet key safety and mental-health requirements.
