Efficacy and Tolerability of Erenumab in the Prophylactic Treatment of Persistent Post-Traumatic Headache


Brief description of study

An exploratory open-label study of PPTH patients to study the efficacy and tolerability of erenumab in the prophylactic treatment of persistent headache attributed to mild traumatic injury to the head. Approximately 100 subjects will be included to erenumab 140 mg. Patients who have participated in study with prior provocation (Ethics Committee of the Capital Region of Denmark (H-1801147 and H-18050498) and who have consented to be contacted will primarily be included. The study will begin February 2019 and is expected to last one year. Patients responding to advertisement (see add) will be contacted by phone.

Detailed Study Description

The reasons and justification of choosing an open-label design are the following:

  1. To date, there are no evidence for prophylactic drugs treating post-traumatic headache. Post-traumatic headache patients are notoriously known to be refractory to prophylactic treatment and have usually tried several prophylactic drugs such as amitriptylin, which is recommended as a prophylactic drug in migraine and chronic tension-type headache, and other drugs developed for the treatment of primary headache disorders. First step is therefore to show if there is an effect at all following erenumab treatment in these refractory PPTH patients.
  2. The refractory nature of PPTH will lower the bias that could occur through placebo effects.
  3. The treatment period is also quite long, and the endpoint is assessed in the last month of treatment, which will also minimize a placebo effect.
  4. Furthermore, this relatively small exploratory open label study is needed to show if there is an effect of erenumab in post-traumatic headache at all and what this effect is, before initiating larger multicenter double-blind studies in this patient group.
