Generic drug: eculizumab
Brand name: Soliris
What is Soliris (eculizumab), and how does it work?
Soliris (eculizumab) is a prescription medicine called a monoclonal antibody. Soliris is used to treat:
- patients-with a disease called Paroxysmal Nocturnal Hemoglobinuria (PNH).
- adults and children with a disease called atypical Hemolytic Uremic Syndrome (aHUS). Soliris is not for use in treating people with Shiga toxin E. coli related hemolytic uremic syndrome (STECHUS).
- adults with a disease called generalized myasthenia gravis (gMG) who are anti-acetylcholine receptor (AchR) antibody positive
- adults with a disease called neuromyelitis optica spectrum disorder (NMOSD) who are anti-aquaporin-4 (AQP4) antibody positive.
It is not known if Soliris is safe and effective in children with PNH, gMG, or NMOSD.
What are the side effects of Soliris?
WARNING
SERIOUS MENINGOCOCCAL INFECTIONS
Life-threatening and fatal meningococcal infections have occurred in patients
treated with Soliris. Meningococcal infection may become rapidly
life-threatening or fatal if not recognized and treated early.
- Comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for meningococcal vaccination in patients with complement deficiencies.
-
Immunize patients with meningococcal vaccines at least 2 weeks prior to
administering the first dose of Soliris, unless the risks of delaying
Soliris therapy outweigh the risk of developing a meningococcal infection. - Vaccination reduces, but does not eliminate, the risk of meningococcal infections. Monitor patients for early signs of meningococcal infections and evaluate immediately if infection is suspected.
Soliris is available only through a restricted program under a Risk Evaluation
and Mitigation Strategy (REMS). Under the Soliris REMS, prescribers must enroll
in the program. Enrollment in the Soliris REMS program and additional information are available by telephone: 1-888-Soliris (1888-765-4747) or at www.solirisrems.com.

What drugs interact with Soliris?
No information provided
Is Soliris safe to use while pregnant or breastfeeding?
- Limited data on outcomes of pregnancies that have occurred following Soliris use in pregnant women have not identified a concern for specific adverse developmental outcomes (see Data).
- There are risks to the mother and fetus associated with untreated paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS) in pregnancy.
- Although limited published data does not report detectable levels of eculizumab in human milk, maternal IgG is known to be present in human milk.
- Available information is insufficient to inform the effect of eculizumab on the breastfed infant. There are no data on the effects of eculizumab on milk production.
- The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Soliris and any potential adverse effects on the breastfed child from eculizumab or from the underlying maternal condition.
