Emgality®▼(galcanezumab): Use with COVID-19 Vaccines
The use of vaccines against SARS-CoV-2 in patients treated with galcanezumab has not been studied by Lilly.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an emerging virus that has caused the recent COVID-19 pandemic. Currently, efforts are underway to develop vaccines against SARS-CoV-2 and these vaccines are expected to be available in the coming months.1,2
SARS-CoV-2 Live vs Nonlive or Inactivated Vaccines
According to current available information on SARS-CoV-2 vaccines being developed, the majority are nonlive.3 However, this is an unprecedented and evolving situation, so it is advisable to check for updated information. For the most up-to-date information regarding each vaccine in development, including the type of each vaccine, please check the World Health Organization and European Medicines Agency at
Immunization Prior to or During Therapy With Galcanezumab
The use of a SARS-CoV-2 vaccine in patients treated with galcanezumab has not been studied by Lilly.
Eli Lilly and Company has not evaluated the safety and efficacy of galcanezumab in combination with vaccines, including SARS-CoV2 vaccines.
Based on the mechanism of action and mechanism of elimination of galcanezumab, there is no reason to expect an interaction with the host immune system.
The decision to administer a vaccination to a patient prior to, during, or after galcanezumab treatment must be based on the clinical judgment of the prescribing healthcare practitioner after careful consideration of the patient's risk factors as well as the risks and benefits of vaccination.
CGRP mAbs Have no Direct Specific Immunomodulatory Effect
The CGRP mAbs have been engineered to bind to either the CGRP peptide or receptor with high specificity and minimized interaction with the immune system.4-6 As CGRP is not an immune system target, CGRP mAbs have no direct immunomodulatory effect.
