Abstract

Background

Chronic migraine (CM) and episodic migraine (EM) are associated with substantial headache-related disability, poor quality of life and global societal burden. In this subgroup analysis from the CONQUER study, we report efficacy outcomes from a pre-specified analysis of galcanezumab versus placebo in patients with CM or EM and 3–4 prior preventive medication category failures due to inadequate efficacy (after at least 2 months at maximum tolerated dose), or safety or tolerability reasons. The patient population is of particular interest due to evidence of decreased quality of life and increased economic burden among patients with migraine that is inadequately managed and is of interest to decision-makers globally.

Methods

Key outcomes included overall mean change from baseline in monthly migraine headache days and proportions of patients achieving ≥30% (CM), ≥50%, and ≥ 75% reduction (response rates) in monthly migraine headache days across Months 1–3. Patient functioning and disability were evaluated at Month 3.

Results

Of the 462 randomized patients, 186 (40.3%) had a history of 3–4 preventive category failures. Galcanezumab versus placebo resulted in significantly (P ≤ .001) larger overall mean reduction in monthly migraine headache days (total: − 5.49 versus − 1.03; CM: − 6.70 versus − 1.56; EM: − 3.64 versus − 0.65). Similarly, the ≥50% response rate was significantly (P ≤ .001) higher with galcanezumab versus placebo (total: 41.0 versus 12.7; CM: 41.5 versus 8.4; EM: 41.1 versus 16.5). In the CM group, the ≥30% response rate was significantly higher in the galcanezumab group than the placebo group (CM, 57.5 versus 19.8, P ≤ .0001) as was the ≥75% response rate (13.3 versus 2.6, P ≤ .05). Galcanezumab also resulted in significant (P < .0001) improvements in patient functioning and reductions in disability.

Conclusions

Galcanezumab was effective in a difficult-to-treat population of patients with CM or EM who had failed 3–4 prior preventive medication categories.
