Warnings

Black Box Warnings

Meningococcal infections/sepsis

  • Life-threatening meningococcal infections/sepsis reported
  • Meningococcal infection may become rapidly life-threatening or fatal if not recognized and treated early
  • Comply with the most current ACIP recommendations for meningococcal vaccination in patients with complement deficiencies
  • Immunize patients with meningococcal vaccines at least 2 weeks prior to administering the first ravulizumab dose, unless the risks of delaying ravulizumab outweigh the risk of developing a meningococcal infection
  • Vaccination reduces, but does not eliminate, meningococcal infection risk
  • Monitor for early signs of meningococcal infections and evaluate immediately if infection is suspected

Risk evaluation and mitigation strategy (REMS)

  • Available only through REMS program
  • Prescribers must enroll in the program
  • Prescribers must counsel patients about risk of meningococcal infection/sepsis, provide patients with REMS educational materials, and ensure patients are vaccinated with meningococcal vaccines
  • Enrollment and additional information available: 1-844-259-6783 or www.ultomirisrems.com

Contraindications

Unresolved Neisseria meningitidis infection

Patients who are not currently vaccinated against Neisseria meningitidis, unless the risks of delaying treatment outweigh the risks of developing a meningococcal infection

Cautions

Life-threatening meningococcal infections reported; vaccinate according to ACIP guidelines ideally at least 2 weeks before initiating ravulizumab

Ravulizumab blocks terminal complement activation; therefore, an increased susceptibility to encapsulated bacterial infections is possible, especially infections caused by N meningitidis but also Streptococcus pneumoniae, Haemophilus influenzae, and to a lesser extent, Neisseria gonorrhoeae

Inform patients of signs and symptoms and steps to be taken to seek immediate medical care for meningococcal infection; may become rapidly life-threatening or fatal if not recognized and treated early; consider discontinuation of therapy in patients who are undergoing treatment for serious meningococcal infection

Monitor for hemolysis signs and symptoms after discontinuing ravulizumab, including elevated LDH with sudden decrease in PNH clone size or hemoglobin, or reappearance of symptoms (eg, fatigue, hemoglobinuria, abdominal pain, dyspnea, thrombosis, dysphagia, erectile dysfunction); monitor any patient who discontinues treatment for at least 16 weeks to detect hemolysis and other reactions

Effect of discontinuing anticoagulants during ravulizumab therapy is not established; therefore, do not alter anticoagulant management

Infusion reactions occurred clinical trials, but did not require discontinuation; interrupt infusion and institute appropriate supportive measures if signs of cardiovascular instability or respiratory compromise occur

Minimum duration of treatment of aHUS should be 6 months; treatment duration beyond initial 6 months should be individualized; after discontinuing treatment, monitor for clinical symptoms and laboratory signs of TMA complications for at least 12 months; if TMA complications occur after discontinuation, consider reinitiating ravulizumab treatment or appropriate organ-specific supportive measures

Pregnancy

Pregnancy

No data are available for use in pregnant women to inform a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes

There are risks to the mother and fetus associated with untreated PNH or aHUS, including preeclampsia and preterm delivery, and adverse fetal/neonatal outcomes, including intrauterine growth restriction (IUGR), fetal death and low birth weight

Animal studies

  • Mouse analogue of the ravulizumab-cwvz molecule (murine anti-C5 antibody) showed increased rates of developmental abnormalities and an increased rate of dead and moribund offspring at doses 0.8-2.2 times the human dose

Clinical considerations

  • PNH in pregnancy is associated with adverse maternal outcomes, including worsening cytopenias, thrombotic events, infections, bleeding, miscarriages, and increased maternal mortality, and adverse fetal outcomes, including fetal death and premature delivery

Lactation

There are no data on the presence of ravulizumab in human milk, the effects on the breastfed child, or the effects on milk production

Because many drugs are excreted in human milk and because of the potential for adverse reactions in a breastfed child, advise lactating women not to breastfeed while receiving ravulizumab and for 8 months after the last dose

Pregnancy Categories

A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

NA: Information not available.

Pharmacology

Mechanism of Action

Monoclonal antibody that is a terminal complement inhibitor

It specifically binds to complement protein C5 with high affinity, thereby inhibiting cleavage to C5a (proinflammatory anaphylatoxin) and C5b (initiating subunit of the terminal complement complex [C5b-9]) and preventing the generation of the terminal complement complex C5b9

Inhibits terminal complement-mediated intravascular hemolysis in patients with PNH

Absorption

Peak plasma concentration

  • Loading dose (PNH): 771 mcg/mL (complement inhibitor-naïve); 843 mcg/mL (previously-treated eculizumab)
  • Maintenance dose (PNH): 1379 mcg/mL (complement inhibitor-naïve); 1386 mcg/mL (previously-treated eculizumab)
  • Loading dose (aHUS): 656 mcg/mL (<20 kg); 600 mcg/mL (≥20 to <40 kg); 754 mcg/mL (≥40 kg)
  • Maintenance dose (aHUS): 1467 mcg/mL (<20 kg); 1863 mcg/mL (≥20 to <40 kg); 1458 mcg/mL (≥40 kg)

Minimum plasma concentration

  • Loading dose (PNH): 391 mcg/mL (complement inhibitor-naïve); 405 mcg/mL (previously-treated eculizumab)
  • Maintenance dose (PNH): 473 mcg/mL (complement inhibitor-naïve); 501 mcg/mL (previously-treated eculizumab)
  • Loading dose (aHUS): 241 mcg/mL (<20 kg); 186 mcg/mL (≥20 to <40 kg); 313 mcg/mL (≥40 kg)
  • Maintenance dose (aHUS): 683 mcg/mL (<20 kg); 549 mcg/mL (≥20 to <40 kg); 507 mcg/mL (≥40 kg)

Distribution

Vd (steady-state): 5.34 L (PNH); 5.22 L (aHUS)

Elimination

Half-life: 49.7 days (PNH); 51.8 days (aHUS)

Clearance: 0.08 L/day (PNH); 0.08 L/day (aHUS)
