• Introduction: Ravulizumab is a potent and selective complement 5 (C5) inhibitor. It is a humanized monoclonal IgG2/4 kappa antibody produced in Chinese hamster ovary (CHO) cells. Ravulizumab was engineered from eculizumab, another complement inhibitor, to increase the duration of action and reduce the frequency of drug administration. It works by blocking terminal complement-mediated inflammation, cell activation, and cell lysis in blood disorders associated with the destruction of red blood cells, thrombosis, and impaired bone marrow function. Ravulizumab was first approved by the FDA on December 21, 2018, for the treatment of paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome in children and adults. It was later approved by the European Commission on July 2, 2019, for the same indications. Ravulizumab is also used to treat myasthenia gravis. Ravulizumab is currently being investigated for the treatment of Coronavirus disease (COVID-19)-induced microvasculature injury and endothelial damage leading to thrombotic microangiopathy (TMA) causing acute kidney injury (AKI).

Pharmaceutical Information

• Pharmacodynamics: Ravulizumab is a potent long-acting complement inhibitor of C5, which is a key complement protein involved in inflammatory and thrombotic pathways. It has a long duration of action and fast onset of action. In a clinical study of adult and pediatric patients with paroxysmal nocturnal hemoglobinuria, completion inhibition of free C5-determined as the serum concentration of less than 0.5 mcg/mL-was observed by the end of the first ravulizumab infusion: this effect was sustained throughout the entire 26-week treatment period. In patients with atypical hemolytic uremic syndrome, inhibition of C5 was observed in 93% of the patients in the study. C5 inhibition by ravulizumab is exposure-dependent.
• Targets: Complement C5
