Exclusion criteria
Exclusion criteria: • Women who are pregnant or lactating • Participants who, in the investigators opinion, have a history of or have evidence of a medical or psychiatric condition that would expose them to an increased risk of a significant adverse event or would interfere with the assessments of efficacy and tolerability during this trial • Participants using any drug or having any medical condition which might interact adversely with, or interfere with the action of, the study medication • Participants who are allergic to or have shown hypersensitivity to verapamil or agents similar to verapamil • Participants who abuse opioids or have a history of significant drug or alcohol abuse within the past year as determined by investigator • Participants who have participated in an investigational drug trial in the 30 days prior to the screening visit • Participants with liver or kidney disease • Participants with cardiopathology contraindicating verapamil administration (second or third grade atrioventricular block, sinoatrial block, sinus node syndrome, heart rate <50/minute, or systolic blood pressure <90 mm Hg) • Participants with previous adynamic ileus • Participants with chronic cluster headache • Use of antipsychotic, antidepressants, lithium or other prophylactic treatment less than one month prior to inclusion
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of this study is to assess the safety of R-verapamil. The safety assessments include: - adverse events - clinical laboratory measurements (chemistry and hematology) - vital signs - physical examinations - ECGs (will be obtained on Day 8 prior to the single 75 mg dose of R-verapamil and at 1 hour post dose and at the end of study visit) ;Secondary Objective: The secondary objective is to evaluate the effectiveness of R-verapamil in the prevention of episodic cluster headaches ;Primary end point(s): Change in the average daily frequency of attacks. ;Timepoint(s) of evaluation of this end point: Change in the average daily frequency of attacks between the baseline run-in period and the end of the 2 week treatment period | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Change in the average daily frequency of attacks - Change in intensity of attacks - Change in duration of attacks - Change in consumption of abortive agents - Patient acceptability of treatment on a 0-10 scale - Change in headache severity index - Change in Hit-6 disability score - R-verapamil-responders - Placebo-responders ;Timepoint(s) of evaluation of this end point: - Change in intensity of attacks, duration of attacks, headache severity index, Hit-6 disability score and in consumption of abortive agents by diary between the baseline run-in period and the end of the 1 and 2 week treatment periods - Patient acceptability of treatment on a 0-10 scale at the end of the 2 week treatment period. - R-verapamil-responders at the end of the 1 and 2 week treatment periods - Placebo-responders at the end of the 1 and 2 week treatment periods | — |
