The US FDA requires a Risk Evaluation and Mitigation Strategy (REMS) for pegcetacoplan. It includes a medication guide, elements to assure safe use, and an implementation system. For additional information: https://www.accessdata.fda.gov/scripts/cder/rems/index.cfm
US BOXED WARNINGS:
SERIOUS INFECTIONS CAUSED BY ENCAPSULATED BACTERIA:
- Meningococcal infections may occur in patients treated with pegcetacoplan and may become rapidly life-threatening or fatal if not recognized and treated early. Its use may predispose individuals to serious infections, especially those caused by encapsulated bacteria, such as Streptococcus pneumoniae, Neisseria meningitidis types A, C, W, Y, and B, and Haemophilus influenzae type B.
- In patients with altered immunocompetence associated with complement deficiencies, it is recommended to comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for vaccinations against encapsulated bacteria.
- To reduce the risk of serious infections, it is recommended to vaccinate patients against encapsulated bacteria as recommended at least 2 weeks prior to administering the first dose unless the risks of delaying therapy outweigh the risk of developing a serious infection.
- Monitor for early signs of serious infections and evaluate immediately if infection is suspected.
- Pegcetacoplan is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS). Prescribers must enroll in the program.
- Hypersensitivity to the active component or any of the ingredients
- Not currently vaccinated against certain encapsulated bacteria, unless the risks of delaying treatment outweigh the risks of developing a bacterial infection with an encapsulated organism
- Unresolved serious infection caused by encapsulated bacteria including Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae
Safety and efficacy have not been established in patients younger than 18 years.
