Abstract
Objective
Acupuncture and fremanezumab are second-line treatments for migraine prophylaxis. We aimed to compare acupuncture with fremanezumab in the preventive treatment of episodic migraine by using a matching-adjusted indirect comparison analysis (MAIC).
Methods
We acquired participant-level data from an acupuncture trial recruiting 302 participants and summary-level data from a fremanezumab trial recruiting 875 participants (290 participants received monthly fremanezumab [MF] and 291 received single-dose fremanezumab [SF]). The primary outcome was the mean reduction in monthly headache days. The secondary outcomes were the mean reduction in monthly moderate-to-severe headache days, days with acute medication, and the adverse events rate.
Results
Before matching, the acupuncture arm had significantly lower BMI, fewer headache days with at least moderate severity, and fewer days with acute medication. After matching, the baseline variables were comparable between groups. The three arms had no difference in the change of monthly migraine days (MF vs. acupuncture: mean difference 0.3, 95%CI −0.5 to 1.1, p-value = 0.473; SF vs. acupuncture: mean difference 0.5, 95%CI −0.3 to 1.3, p-value = 0.214). The results were similar in the analyses of secondary outcomes sensitivity analyses. Thirty-six (25%) participants in the acupuncture arm reported adverse events, versus 192(66%) participants in the MF arm and 193 (66%) in the SF arm.
Conclusion
The preventive treatment effect of acupuncture is equivalent to fremanezumab, and it presented with a lower adverse event rate, which indicates that acupuncture can be an alternative to fremanezumab.
