Brief Summary:

It has previously been shown that nitroglycerine induces cluster headache attacks in episodic cluster headache patients (ECH patients) in bouts but not in remission phase. Furthermore, plasma concentrations of calcitonin gene-related peptide (CGRP) have been shown to be significantly higher during, but not before and after, an attack.

The attack appears around 20-40 min after nitroglycerine infusion with vasodilatation. During this latency period preceding the attack, no increase in CGRP plasma concentrations is seen. CGRP induces migraine attacks in 65% of migraine patients, and CGRP antagonists as well as monoclonal antibodies against CGRP are effective in migraine treatment.

Based on the above the investigators hypothesize the following:

  1. Provoking ECH patients in bout with CGRP triggers cluster headache attacks
  2. Provoking ECH patients in remission with CGRP does not trigger cluster headache attacks
  3. Provoking chronic cluster headache patients with CGRP triggers cluster headache attacks more often than in ECH patients.

Arm Intervention/treatment
Active Comparator: Active
1.5µg/min IV calcitonin-gene related peptide for 20 minutes
Drug: Calcitonin-Gene Related Peptide
1,5 µg/min of IV CGRP over 20 mins
Other Name: CGRP

Placebo Comparator: Placebo
IV placebo for 20 minutes
Drug: Placebo
40 ml of normal saline over 20 mins

Primary Outcome Measures :
  1. Differences in occurence of cluster headache attacks on CGRP day compared to placebo day in all three groups [ Time Frame: 90 min after administration of study drug ]
    Occurence of experimentally induced cluster headache attack yes/no

  2. AUC headache on CGRP day compared to placebo day in all three groups [ Time Frame: 90 min after administration of study drug ]
    Using 90 min headache questionnaire

  3. Time to maximum headache score on CGRP day compared to placebo day in all three [ Time Frame: 90 min after administration of study drug ]
    Using 90 min headache questionnaire
