  • 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

ULTOMIRIS, unless the risks of delaying ULTOMIRIS therapy outweigh the risks of developing a meningococcal infection

  • Vaccination reduces, but does not eliminate, the risk of meningococcal infection
    • Monitor patients for early signs of meningococcal infections, and evaluate immediately if infection is

suspected ULTOMIRIS is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS). Under the ULTOMIRIS REMS, prescribers must enroll in the program Enrollment in the ULTOMIRIS REMS program and additional information are available by telephone: 1- 888-765-4747 or at www.ultomirisrems.com.

|fdaLIADAdult=

Revefenacin is indicated for:

  • The treatment of patients with chronic obstructive pulmonary disorder
    • Should not be given to patients experiencing life threatening episodes
    • In other words, Revefenacin should not be used as a rescue drug
  • Discontinue the drug if patients appears to suffer from paradoxical bronchospasm or hypersensitivity reactions

Limitations of Use

  • Revefenacin delivered via jet nebulizer can result in "longer administration time, variability in residual volume and particle size, daily cleaning requirements, limited portability, and need for device assembly"
    • The benefits may outweigh this because some patients are required to use nebulizers

Dosage

  • The agreed dosage is 175 micrograms per day
    • Taken via a standard jet nebulizer (turns liquid medication into mist) connected to an air compressor
    • Makes it easy for patients with pulmonary problems
  • The dosing schedule is allowed to occasionally vary within 7 days of the scheduled infusion day (except for the first maintenance dose of ULTOMIRIS); but the subsequent doses should be administered according to the original schedule.

Dosing Considerations

  • Patients are not allowed to use nephrotoxic or hepatotoxic medications for 4 weeks before drug administration
    • They may use the following medications: acetaminophen, ibuprofen, milk of magnesia (magnesium hydroxide), and routine vitamins and minerals

Administration of Revefenacin

  • Only administer as an intravenous infusion.
  • Intravenous solution in healthy volunteers
    • Volume of distribution was 218 L
    • Intravenous solution radioactivity:
    • 54% came out as solid waste
    • 27% came out as liquid waste

Serious Meningococcal Infections

  • The use of ULTOMIRIS increases a patient’s susceptibility to serious meningococcal infections

(septicemia and/or meningitis). Meningococcal disease due to any serogroup may occur.

  • Immunize patients without a history of meningococcal vaccination at least 2 weeks prior to receiving

the first dose of ULTOMIRIS. If urgent ULTOMIRIS therapy is indicated in an unvaccinated patient, administer meningococcal vaccine(s) as soon as possible and provide patients with 2 weeks of antibacterial drug prophylaxis.

  • Vaccination reduces, but does not eliminate, the risk of meningococcal infections.
  • Closely monitor patients for early signs and symptoms of meningococcal infection and evaluate

patients immediately if infection is suspected.

  • If ULTOMIRIS therapy is administered to patients with active systemic infections, monitor closely for

signs and symptoms of worsening infection.

  • In clinical studies, 59 patients with PNH were treated with ULTOMIRIS less than 2 weeks after

meningococcal vaccination. All of these patients received antibiotics for prophylaxis of meningococcal infection until at least 2 weeks after meningococcal vaccination. The benefits and risks of antibiotic prophylaxis for prevention of meningococcal infections in patients receiving ULTOMIRIS have not been established.

  • In PNH clinical studies, 3 out of 261 PNH patients developed serious meningococcal infections/sepsis

while receiving treatment with ULTOMIRIS; all 3 had been vaccinated. These 3 patients recovered while continuing treatment with ULTOMIRIS.

Other Infections
  • ULTOMIRIS blocks terminal complement activation; therefore, patients may have increased

susceptibility to encapsulated bacteria infections, especially infections caused by Neisseria meningitidis

but also Streptococcus pneumoniae, Haemophilus influenzae, and to a lesser extent, Neisseria gonorrhoeae.

  • Children treated with ULTOMIRIS may be at increased risk of developing serious infections due to

Streptococcus pneumoniae and Haemophilus influenzae type b (Hib).

    • Administer vaccinations for the prevention of Streptococcus pneumoniae and Haemophilus

influenzae type b (Hib) infections accordingto ACIP guidelines.

Clinical Studies

Trials:

  • Revefenacin proved to have long duration of action and low systemic exposure (doesn't affect the whole body) for patients struggling with Chronic Obstructive Pulmonary Disease or COPD
  • 88 mcg of this drug can result in constructive bronchodilation (to helps patients breathe better)

Pharmacology trials:

  • Evaluted human recombitance mAChRs (muscarinic cholinergic receptor) by testing it on airway tissues from rats, guinea pigs, and humans
    • Revefenacin proved high affinity for the human tissue and competed against those five human recombinant mAChRs
    • This drug attacked "mAChRs mediated contractile responses"
    • This shows that revefenacin produces long-lasting attacking effects on this tissue from rats, guinea pigs, and humans

overdose

There is limited information regarding Revefenacin overdosage. If you suspect drug poisoning or overdose, please contact the National Poison Help hotline (1-800-222-1222) immediately.

|mechAction= *Ravulizumab-cwvz is a terminal complement inhibitor that specifically binds to the complement protein C5 with high affinity, thereby inhibiting its cleavage to C5a (the proinflammatory anaphylatoxin) and C5b (the initiating subunit of the terminal complement complex [C5b-9]) and preventing the generation of the terminal complement complex C5b9.

  • ULTOMIRIS inhibits terminal complement-mediated intravascular hemolysis in patients with PNH and

complement-mediated thrombotic microangiopathy (TMA) in patients with aHUS.

|structure= There is limited information regarding Revefenacin Structure in the drug label. |PD=

  • The extent and duration of the pharmacodynamic response in patients with PNH and aHUS were

exposure-dependent for ULTOMIRIS. Free C5 levels of <0.5 mcg/mL were correlated with maximal intravascular hemolysis control and complete terminal complement inhibition in patients with PNH.

  • Complete terminal complement inhibition following initiation of ULTOMIRIS treatment led to

normalization of serum LDH by week 4 in complement-inhibitor naïve patients with PNH, and maintained LDH normalization in patients previously treated with eculizumab with PNH.

Use in Specific Populations

  • Revefencin is not affected majorly by age, weight, or gender
  • Hepatic impariment has not been studied to see if there are necessary precautions to take
  • Patients with renal impariment
    • Mesure for antimuscarinic adverse events or the inhibitting of acetocholine, a neurotransmitter in the PNS

Carcinogenesis, Mutagenesis, Impairment of Fertility

  • No animal studies were performed to evaluate the effects of ravulizumab-cwvz on carcinogenesis, or

mutagenesis.

  • Effects of ravulizumab-cwvz upon fertility have not been studied in animals.
    • Intravenous injections of male and female mice with a murine anti-C5 antibody at up to 0.8-2.2 times

the equivalent of the clinical dose of ULTOMIRIS had no adverse effects on mating or fertility.
