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

- 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

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 study tests if a combination of pulsed radiofrequency and platelet-rich plasma can help people with episodic cluster headaches feel better during a cluster period. It is for people whose headaches are not well controlled with standard medicines.
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.
This Phase 2 trial tests whether nerve block injections can reduce pain from episodic migraines. It may help some people who get frequent migraine attacks but are not also using certain migraine preventions or strong pain medicines.
