Emgality® ▼ (galcanezumab): Behandlingsefterlevnad

Behandlingsefterlevnad i kliniska fas 3-studier av galcanezumab för kronisk och episodisk migränförebyggande var hög.

Treatment Compliance in Migraine Clinical Trials

Definition of Treatment Compliance

Galcanezumab has been studied in phase 3 randomized, double-blind, placebo-controlled studies in adult patients for the prevention of

  • episodic migraine (EVOLVE-1 and EVOLVE-2),1,2 and

  • chronic migraine (REGAIN).3

Galcanezumab has also been studied in a phase 3, open-label, 12-month safety study for the prevention of episodic or chronic migraine.4

In the phase 3 clinical trials for migraine prevention, treatment compliance was calculated as the number of completed scheduled dosing visits during the double-blind treatment phase in (EVOLVE-1, EVOLVE-2 and REGAIN) or the open-label treatment phase (CGAJ) divided by the number of completed scheduled dosing visits, including any skipped dosing visits before the last dosing visit or early discontinuation visit.5 

The last dosing visit occurred at

  • visit 10, the last dosing visit in the 6-month double-blind treatment phase in the 2 episodic migraine prevention studies (EVOLVE-1 and EVOLVE-2) during which patients received a total of 6 doses

  • visit 6, the last dosing visit in the 3-month double-blind treatment phase in the chronic migraine prevention study (REGAIN) during which patients received a total of 3 doses, and

  • visit 14, the last dosing visit in the 12-month open-label treatment phase in the long-term open-label safety study (CGAJ) during which patients received a total of 12 doses.5

Treatment Compliance Rates

Treatment compliance was expected to be high in the EVOLVE-1, EVOLVE-2, and REGAIN trials for episodic and chronic migraine because investigative site personnel administered the monthly SQ dose.5 Compliance was also high in CGAJ in which the  first dose was administered by investigative site personnel, and subsequent doses were self-administered either in the office or at home by the patient or by a caregiver: Table 1.

d First dose was administered by ISP and subsequent doses were administered by the patient or a caregiver.

Note: The recommended dose for the prophylaxis of migraine in adults who have at least 4 migraine days per month is 120 mg galcanezumab injected subcutaneously once monthly, with a 240 mg loading dose as the initial dose .6 The results of a maintenance dose of galcanezumab 240 mg once monthly are also described here. Even though this dose has been tested in pivotal studies, it has not been approved and therefore is not recommended.
