C3G/Primary IC-MPGN

EMPAVELI safety1,2

Safety data from the VALIANT trial1

Adverse reactions reported in ≥5% of patients (adult and pediatric) treated with EMPAVELI and greater than placebo1

*Term includes the following reactions at the infusion site: erythema, pruritus, swelling, bruising, induration, pain, hemorrhage, discomfort, edema, rash, and hypoesthesia.

  • Serious adverse reactions due to viral infections resulting in hospitalizations occurred in 2 patients (3%) with C3G or primary IC-MPGN receiving EMPAVELI and 1 patient (2%) on placebo
  • One patient (2%) on EMPAVELI with native kidney C3G died because of respiratory failure due to COVID-19 pneumonia; there were no deaths in the placebo arm
  • The placebo-controlled period of VALIANT was followed by a 26-week open-label period (OLP). During the OLP, 1 patient with native kidney C3G had a serious adverse event of pneumonia secondary to Streptococcus pneumoniae, and 1 patient with recurrent C3G following kidney transplant developed herpes zoster meningoencephalitis while on concomitant immunosuppression, leading to treatment discontinuation
  • In the Phase 2 study in 13 adults with recurrent C3G or primary IC-MPGN after kidney transplant, 1 patient with primary IC-MPGN experienced a serious adverse event of Pneumocystis jirovecii pneumonia while on EMPAVELI and concurrent immunosuppressive medications
  • No cases of encapsulated meningococcal infection were reported in any C3G or primary IC-MPGN patient treated with EMPAVELI in the VALIANT trial. Patients were vaccinated according to Advisory Committee on Immunization Practices (ACIP) guidelines prior to treatment with EMPAVELI2
Observed safety by subgroup in VALIANT trial

Observed safety in pediatric patients (12 to <18 years old)1,3

  • Adverse reactions in pediatric patients were similar to those seen in adults
  • Frequency and severity of TEAEs were similar between treatment arms
    • Frequency: 82.1% (n=23) with EMPAVELI, 96.3% (n=26) with placebo
    • Severity: serious TEAEs in 10.7% (n=3) with EMPAVELI, 11.1% (n=3) with placebo
  • In the EMPAVELI arm, 1 serious TEAE (pyrexia) was considered related to treatment
  • No transplant rejection or allograft loss was observed in post-transplant C3G pediatric patients
  • There were no deaths in pediatric patients

Safety and effectiveness of EMPAVELI in patients with recurrent IC-MPGN following kidney transplant have not been established.1

TEAE=treatment-emergent adverse event.

Observed safety in post-transplant recurrent C3G patients4

  • No TEAEs led to treatment discontinuation at Week 26 in the RCP
  • No deaths, transplant rejection, or allograft loss were reported in post-transplant recurrent C3G patients

Safety and effectiveness of EMPAVELI in patients with recurrent IC-MPGN following kidney transplant have not been established.1

RCP=randomized controlled period; TEAE=treatment-emergent adverse event.

†Influenza (moderate), nasopharyngitis (mild), and viral infection (moderate); 1 each.

‡Nasopharyngitis (mild).

§Proteinuria and tubulointerstitial nephritis; 1 each.

EMPAVELI can be self-administered twice weekly with an innovative device1

IMPORTANT SAFETY INFORMATION

WARNING: SERIOUS INFECTIONS CAUSED BY ENCAPSULATED BACTERIA

EMPAVELI, a complement inhibitor, increases the risk of serious infections, especially those caused by encapsulated bacteria, such as Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae type B. Life-threatening and fatal infections with encapsulated bacteria have occurred in patients treated with complement inhibitors. These infections may become rapidly life-threatening or fatal if not recognized and treated early.

  • Complete or update vaccination for encapsulated bacteria at least 2 weeks prior to the first dose of EMPAVELI, unless the risks of delaying therapy with EMPAVELI outweigh the risks of developing a serious infection. Comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for vaccinations against encapsulated bacteria in patients receiving a complement inhibitor.
  • Patients receiving EMPAVELI are at increased risk for invasive disease caused by encapsulated bacteria, even if they develop antibodies following vaccination. Monitor patients for early signs and symptoms of serious infections and evaluate immediately if infection is suspected.

Because of the risk of serious infections caused by encapsulated bacteria, EMPAVELI is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the EMPAVELI REMS.

CONTRAINDICATIONS

  • Hypersensitivity to pegcetacoplan or to any of the excipients
  • For initiation in patients with unresolved serious infection caused by encapsulated bacteria including Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae type B

WARNINGS AND PRECAUTIONS

Serious Infections Caused by Encapsulated Bacteria

EMPAVELI, a complement inhibitor, increases a patient’s susceptibility to serious, life-threatening, or fatal infections caused by encapsulated bacteria including Streptococcus pneumoniae, Neisseria meningitidis (caused by any serogroup, including non-groupable strains), and Haemophilus influenzae type B. Life-threatening and fatal infections with encapsulated bacteria have occurred in both vaccinated and unvaccinated patients treated with complement inhibitors. The initiation of EMPAVELI treatment is contraindicated in patients with unresolved serious infection caused by encapsulated bacteria.

Complete or update vaccination against encapsulated bacteria at least 2 weeks prior to administration of the first dose of EMPAVELI, according to the most current ACIP recommendations for patients receiving a complement inhibitor. Revaccinate patients in accordance with ACIP recommendations considering the duration of therapy with EMPAVELI. Note that ACIP recommends an administration schedule in patients receiving complement inhibitors that differs from the administration schedule in the vaccine prescribing information. If urgent EMPAVELI therapy is indicated in a patient who is not up to date with vaccines against encapsulated bacteria according to ACIP recommendations, provide the patient with antibacterial drug prophylaxis and administer these vaccines as soon as possible. The benefits and risks of treatment with EMPAVELI, as well as the benefits and risks of antibacterial drug prophylaxis in unvaccinated or vaccinated patients, must be considered against the known risks for serious infections caused by encapsulated bacteria.

Vaccination does not eliminate the risk of serious encapsulated bacterial infections, despite development of antibodies following vaccination. Closely monitor patients for early signs and symptoms of serious infection and evaluate patients immediately if an infection is suspected. Inform patients of these signs and symptoms and instruct patients to seek immediate medical care if these signs and symptoms occur. Promptly treat known infections. Serious infection may become rapidly life-threatening or fatal if not recognized and treated early. Consider interruption of EMPAVELI in patients who are undergoing treatment for serious infections.

EMPAVELI is available only through a restricted program under a REMS.

EMPAVELI REMS

EMPAVELI is available only through a restricted program under a REMS called EMPAVELI REMS, because of the risk of serious infections caused by encapsulated bacteria. Notable requirements of the EMPAVELI REMS include the following:

Under the EMPAVELI REMS, prescribers must enroll in the program. Prescribers must counsel patients about the risks, signs, and symptoms of serious infections caused by encapsulated bacteria, provide patients with the REMS educational materials, ensure patients are vaccinated against encapsulated bacteria at least 2 weeks prior to the first dose of EMPAVELI, prescribe antibacterial drug prophylaxis if patients’ vaccine status is not up to date and treatment must be started urgently, and provide instructions to always carry the Patient Safety Card both during treatment, as well as for 2 months following last dose of EMPAVELI. Pharmacies that dispense EMPAVELI must be certified in the EMPAVELI REMS and must verify prescribers are certified.

Infusion-Related Reactions

Systemic hypersensitivity reactions (eg, facial swelling, rash, urticaria, pyrexia) have occurred in patients treated with EMPAVELI, which may resolve after treatment with antihistamines. Cases of anaphylaxis leading to treatment discontinuation have been reported. If a severe hypersensitivity reaction (including anaphylaxis) occurs, discontinue EMPAVELI infusion immediately, institute appropriate treatment, per standard of care, and monitor until signs and symptoms are resolved.

Interference with Laboratory Tests

There may be interference between silica reagents in coagulation panels and EMPAVELI that results in artificially prolonged activated partial thromboplastin time (aPTT); therefore, avoid the use of silica reagents in coagulation panels.

ADVERSE REACTIONS

Most common adverse reactions in adult and pediatric patients 12 years of age and older with C3G or primary IC-MPGN (incidence ≥10%) were infusion-site reactions, pyrexia, nasopharyngitis, influenza, cough, and nausea.

USE IN SPECIFIC POPULATIONS

Females of Reproductive Potential

EMPAVELI may cause embryo-fetal harm when administered to pregnant women. Pregnancy testing is recommended for females of reproductive potential prior to treatment with EMPAVELI. Advise female patients of reproductive potential to use effective contraception during treatment with EMPAVELI and for 40 days after the last dose.

INDICATION

EMPAVELI® (pegcetacoplan) is indicated for the treatment of adult and pediatric patients aged 12 years and older with C3 glomerulopathy (C3G) or primary immune-complex membranoproliferative glomerulonephritis (IC-MPGN), to reduce proteinuria.
