4.1. Therapeutic indications

BEKEMV is indicated in adults and children for the treatment of:

• Paroxysmal nocturnal haemoglobinuria (PNH).

Evidence of clinical benefit is demonstrated in patients with haemolysis with clinical symptom(s) indicative of high disease activity, regardless of transfusion history (see section 5.1).

• Atypical haemolytic uraemic syndrome (aHUS) (see section 5.1).

4.2. Posology and method of administration

BEKEMV must be administered by a healthcare professional and under the supervision of a physician experienced in the management of patients with haematological and renal disorders.

Home infusion may be considered for patients who have tolerated infusions well in the clinic. The decision of a patient to receive home infusions should be made after evaluation and recommendation from the treating physician. Home infusions should be performed by a qualified healthcare professional.

Posology

PNH in adults

The PNH dosing regimen for adult patients (≥ 18 years of age) consists of a 4-week initial phase followed by a maintenance phase:

• Initial phase: 600 mg of BEKEMV administered via a 25 – 45 minute (35 minutes ± 10 minutes) intravenous infusion every week for the first 4 weeks.

• Maintenance phase: 900 mg of BEKEMV administered via a 25 – 45 minute (35 minutes ± 10 minutes) intravenous infusion for the fifth week, followed by 900 mg of BEKEMV administered via a 25 – 45 minute (35 minutes ± 10 minutes) intravenous infusion every 14 ± 2 days (see section 5.1).

aHUS in adults

The aHUS dosing regimen for adult patients (≥18 years of age) consists of a 4-week initial phase followed by a maintenance phase:

• Initial phase: 900 mg of BEKEMV administered via a 25 – 45 minute (35 minutes ± 10 minutes) intravenous infusion every week for the first 4 weeks.

• Maintenance phase: 1,200 mg of BEKEMV administered via a 25 – 45 minute (35 minutes ± 10 minutes) intravenous infusion for the fifth week, followed by 1,200 mg of BEKEMV administered via a 25 – 45 minute (35 minutes ± 10 minutes) intravenous infusion every 14 ± 2 days (see section 5.1).

Paediatric patients in PNH and aHUS

Paediatric PNH and aHUS patients with body weight ≥ 40 kg are treated with the adult dosing recommendations, respectively.

BEKEMV is contraindicated in babies and young children below 2 years of age (see section 4.3).

In paediatric PNH and aHUS patients above 2 years of age and with body weight below 40 kg, the BEKEMV dosing regimen consists of:

Patient body weight

Initial phase

Maintenance phase

30 to < 40 kg

600 mg weekly for the first 2 weeks

900 mg at week 3; then 900 mg every 2 weeks

20 to < 30 kg

600 mg weekly for the first 2 weeks

600 mg at week 3; then 600 mg every 2 weeks

10 to < 20 kg

600 mg single dose at week 1

300 mg at week 2; then 300 mg every 2 weeks

5 to < 10 kg

300 mg single dose at week 1

300 mg at week 2; then 300 mg every 3 weeks

Eculizumab has not been studied in patients with PNH who weigh less than 40 kg. The posology of eculizumab to be used in paediatric patients with PNH weighing less than 40 kg is identical to the weight-based dose recommendation provided for paediatric patients with aHUS. Based on the pharmacokinetic (PK)/pharmacodynamic (PD) data available in patients with aHUS and PNH treated with eculizumab, this body-weight based dose regimen for paediatric patients is expected to result in an efficacy and safety profile similar to that in adults.

Supplemental dosing of BEKEMV is required in the setting of concomitant plasmapheresis (PP), plasma exchange (PE), or fresh frozen plasma infusion (PI), as described below:

Abbreviation: IVIg = intravenous immunoglobulin

Treatment monitoring

aHUS patients should be monitored for signs and symptoms of thrombotic microangiopathy (TMA) (see section 4.4 aHUS laboratory monitoring).

BEKEMV treatment is recommended to continue for the patient's lifetime, unless the discontinuation of BEKEMV is clinically indicated (see section 4.4).

Elderly

BEKEMV may be administered to patients aged 65 years and over. There is no evidence to suggest that any special precautions are needed when older people are treated – although experience with eculizumab in this patient population is still limited.

Renal impairment

No dose adjustment is required for patients with renal impairment (see section 5.2).

Hepatic impairment

The safety and efficacy of eculizumab have not been studied in patients with hepatic impairment.

Method of administration

Do not administer as an intravenous push or bolus injection. BEKEMV should only be administered via intravenous infusion as described below.

For instructions on dilution of the medicinal product before administration, see section 6.6.

The diluted solution of BEKEMV should be administered by intravenous infusion over 25 ‑ 45 minutes (35 minutes ± 10 minutes) in adults and 1 - 4 hours in paediatric patients under 18 years of age via gravity feed, a syringe-type pump, or an infusion pump. It is not necessary to protect the diluted solution of BEKEMV from light during administration to the patient.

Patients should be monitored for one hour following infusion. If an adverse event occurs during the administration of BEKEMV, the infusion may be slowed or stopped at the discretion of the physician. If the infusion is slowed, the total infusion time may not exceed two hours in adults and four hours in paediatric patients under 18 years of age.

There is limited safety data supporting home-based infusions, additional precautions in the home setting such as availability of emergency treatment of infusion reactions or anaphylaxis are recommended.

Infusion reactions are described in sections 4.4 and 4.8 on the SmPC.

4.3. Contraindications

Hypersensitivity to eculizumab or to any of the excipients listed in section 6.1.

BEKEMV is contraindicated in babies and young children below 2 years of age since they may not yet be diagnosed with hereditary fructose intolerance (HFI). Medicines containing sorbitol/fructose given intravenously may therefore be life-threatening, and are contraindicated in this population (see section 4.4).

BEKEMV therapy must not be initiated in patients (see section 4.4):

- with unresolved Neisseria meningitidis infection

- who are not currently vaccinated against Neisseria meningitidis unless they receive prophylactic treatment with appropriate antibiotics until 2 weeks after vaccination.

4.4. Special warnings and precautions for use

BEKEMV is not expected to affect the aplastic component of anaemia in patients with PNH.

Meningococcal infection

Due to its mechanism of action, the use of BEKEMV increases the patient's susceptibility to meningococcal infection (Neisseria meningitidis). Meningococcal disease due to any serogroup may occur. To reduce the risk of infection, all patients must be vaccinated at least 2 weeks prior to receiving BEKEMV unless the risk of delaying BEKEMV therapy outweighs the risks of developing a meningococcal infection. Patients who initiate BEKEMV treatment less than 2 weeks after receiving a tetravalent meningococcal vaccine must receive treatment with appropriate prophylactic antibiotics until 2 weeks after vaccination. Vaccines against all available serogroups including A, C, Y, W 135 and B, are recommended in preventing the commonly pathogenic meningococcal serogroups. Patients must be vaccinated and revaccinated according to current national guidelines for vaccination use.

Vaccination may further activate complement. As a result, patients with complement-mediated diseases, including PNH and aHUS, may experience increased signs and symptoms of their underlying disease, such as haemolysis (PNH) or TMA (aHUS). Therefore, patients should be closely monitored for disease symptoms after recommended vaccination.

Vaccination may not be sufficient to prevent meningococcal infection. Consideration should be given to official guidance on the appropriate use of antibacterial agents. Cases of serious or fatal meningococcal infections have been reported in eculizumab-treated patients. Sepsis is a common presentation of meningococcal infections in patients treated with eculizumab (see section 4.8). All patients should be monitored for early signs of meningococcal infection, evaluated immediately if infection is suspected, and treated with appropriate antibiotics if necessary. Patients should be informed of these signs and symptoms and steps taken to seek medical care immediately. Physicians must discuss the benefits and risks of BEKEMV therapy with patients and provide them with a patient guide and a patient card (see package leaflet for a description).

Other systemic infections

Due to its mechanism of action, BEKEMV therapy should be administered with caution to patients with active systemic infections. Patients may have increased susceptibility to infections, especially with Neisseria and encapsulated bacteria. Serious infections with Neisseria species (other than Neisseria meningitidis), including disseminated gonococcal infections, have been reported.

Patients should be provided with information from the package leaflet to increase their awareness of potential serious infections and the signs and symptoms of them. Physicians should advise patients about gonorrhoea prevention.

Infusion reactions

Administration of BEKEMV may result in infusion reactions or immunogenicity that could cause allergic or hypersensitivity reactions (including anaphylaxis). In clinical trials, no PNH or aHUS patients experienced an infusion reaction which required discontinuation of eculizumab. BEKEMV administration should be interrupted in all patients experiencing severe infusion reactions and appropriate medical therapy administered.

Immunisation

Prior to initiating BEKEMV therapy, it is recommended that PNH and aHUS patients initiate immunisations according to current immunisation guidelines. Additionally, all patients must be vaccinated against meningococcal infections at least 2 weeks prior to receiving BEKEMV unless the risk of delaying BEKEMV therapy outweighs the risks of developing a meningococcal infection. Patients who initiate BEKEMV treatment less than 2 weeks after receiving a tetravalent meningococcal vaccine must receive treatment with appropriate prophylactic antibiotics until 2 weeks after vaccination. Vaccines against all available serogroups including A, C, Y W 135 and B are recommended in preventing the commonly pathogenic meningococcal serogroups. Patients must be vaccinated and revaccinated according to current national guidelines for vaccination use (see meningococcal infection).

Patients less than 18 years of age must be vaccinated against Haemophilus influenzae and pneumococcal infections, and strictly need to adhere to the national vaccination recommendations for each age group.

Vaccination may further activate complement. As a result, patients with complement-mediated diseases, including PNH and aHUS may experience increased signs and symptoms of their underlying disease, such as haemolysis (PNH) or TMA (aHUS). Therefore, patients should be closely monitored for disease symptoms after recommended vaccination.

Anticoagulant therapy

Treatment with BEKEMV should not alter anticoagulant management.

PNH laboratory monitoring

PNH patients should be monitored for signs and symptoms of intravascular haemolysis, including serum lactate dehydrogenase (LDH) levels. PNH patients receiving BEKEMV therapy should be similarly monitored for intravascular haemolysis by measuring LDH levels and may require dose adjustment within the recommended 14 ± 2 day dosing schedule during the maintenance phase (up to every 12 days).

aHUS laboratory monitoring

aHUS patients receiving BEKEMV therapy should be monitored for thrombotic microangiopathy by measuring platelet counts, serum LDH and serum creatinine, and may require dose adjustment within the recommended 14±2 day dosing schedule during the maintenance phase (up to every 12 days).

Treatment discontinuation for PNH

If PNH patients discontinue treatment with BEKEMV they should be closely monitored for signs and symptoms of serious intravascular haemolysis. Serious haemolysis is identified by serum LDH levels greater than the pre-treatment level, along with any of the following: greater than 25% absolute decrease in PNH clone size (in the absence of dilution due to transfusion) in one week or less; a haemoglobin level of < 5 g/dL or a decrease of > 4 g/dL in one week or less; angina; change in mental status; a 50% increase in serum creatinine level; or thrombosis. Monitor any patient who discontinues BEKEMV for at least 8 weeks to detect serious haemolysis and other reactions.

If serious haemolysis occurs after BEKEMV discontinuation, consider the following procedures/treatments: blood transfusion (packed RBCs), or exchange transfusion if the PNH RBCs are > 50% of the total RBCs by flow cytometry; anticoagulation; corticosteroids; or reinstitution of BEKEMV. In PNH clinical studies, 16 patients discontinued the eculizumab treatment regimen. Serious haemolysis was not observed.

Treatment discontinuation for aHUS

Thrombotic microangiopathy (TMA) complications have been observed as early as 4 weeks and up to 127 weeks following discontinuation of eculizumab treatment in some patients. Discontinuation of treatment should only be considered if medically justified.

In aHUS clinical studies, 61 patients (21 paediatric patients) discontinued eculizumab treatment with a median follow-up period of 24 weeks. Fifteen severe thrombotic microangiopathy (TMA) complications in 12 patients were observed following treatment discontinuation, and 2 severe TMA complications occurred in an additional 2 patients that received a reduced dosing regimen of eculizumab outside of the approved dosing regimen (see section 4.2). Severe TMA complications occurred in patients regardless of whether they had an identified genetic mutation, high risk polymorphism or auto-antibody. Additional serious medical complications occurred in these patients including severe worsening of kidney function, disease-related hospitalisation and progression to end stage renal disease requiring dialysis. Despite eculizumab re-initiation following discontinuation, progression to end stage renal disease occurred in one patient.

If aHUS patients discontinue treatment with BEKEMV, they should be monitored closely for signs and symptoms of severe thrombotic microangiopathy complications. Monitoring may be insufficient to predict or prevent severe thrombotic microangiopathy complications in patients with aHUS after discontinuation of BEKEMV.

Severe thrombotic microangiopathy complications post discontinuation can be identified by (i) any two, or repeated measurement of anyone, of the following: a decrease in platelet count of 25% or more as compared to either baseline or to peak platelet count during BEKEMV treatment; an increase in serum creatinine of 25% or more as compared to baseline or to nadir during BEKEMV treatment; or, an increase in serum LDH of 25% or more as compared to baseline or to nadir during BEKEMV treatment; or (ii) any one of the following: a change in mental status or seizures; angina or dyspnoea; or thrombosis.

If severe thrombotic microangiopathy complications occur after BEKEMV discontinuation, consider reinstitution of BEKEMV treatment, supportive care with PE/PI, or appropriate organ-specific supportive measures including renal support with dialysis, respiratory support with mechanical ventilation or anticoagulation.

Educational materials

All physicians who intend to prescribe BEKEMV must ensure they are familiar with the guide for Healthcare Professionals to prescribing. Physicians must discuss the benefits and risks of BEKEMV therapy with patients and provide them with a patient guide and a patient card.

Patients should be instructed that if they develop fever, headache accompanied with fever and/or stiff neck or sensitivity to light, they should immediately seek medical care as these signs may be indicative of meningococcal infection.

Excipients with known effect

Sorbitol

This medicine contains 50 mg sorbitol (E420) in each mL. Patients with HFI must not be given this medicine unless strictly necessary.

Babies and young children (below 2 years of age) may not yet be diagnosed with HFI. Medicines (containing sorbitol/fructose) given intravenously may be life-threatening and should be contraindicated in this population (see sections 4.2 and 4.3).

A detailed history with regard to HFI symptoms has to be taken of each patient prior to being given this medicinal product.

Sodium

This medicinal product contains less than 1 mmol of sodium (23 mg) per dose, that is to say essentially “sodium free”.

Polysorbate 80

This medicinal product contains 3.0 mg of polysorbate 80 in each vial (30 mL vial) which is equivalent to 0.3 mg/kg or less at the maximum dose for adult patients and paediatric patients with body weight more than 10 kg and is equivalent to 0.6 mg/kg or less at the maximum dose for paediatric patients with body weight 5 to < 10 kg. Polysorbates may cause allergic reactions.

Traceability

In order to improve traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded.

4.5. Interaction with other medicinal products and other forms of interaction

No interaction studies have been performed. Based on the potential inhibitory effect of eculizumab on complement-dependent cytotoxicity of rituximab, eculizumab may reduce the expected pharmacodynamic effects of rituximab.

Plasma exchange (PE), plasmapheresis (PP), fresh frozen plasma infusion (PI) and intravenous immunoglobulin (IVIg) have been shown to reduce eculizumab serum levels. A supplemental dose of eculizumab is required in these settings. See section 4.2 for guidance in case of concomitant PE, PP, PI, or IVIg treatment.

Concomitant use of eculizumab with intravenous immunoglobulin (IVIg) may reduce effectiveness of eculizumab. Closely monitor for reduced effectiveness of eculizumab.

Concomitant use of eculizumab with neonatal Fc receptor (FcRn) blockers may lower systemic exposures and reduce effectiveness of eculizumab. Closely monitor for reduced effectiveness of eculizumab.

4.6. Fertility, pregnancy and lactation

The use of adequate contraception to prevent pregnancy and for at least 5 months after the last dose of treatment with eculizumab should be considered for women of childbearing potential.

Pregnancy

There are no well-controlled studies in pregnant women treated with eculizumab. Data on a limited number of pregnancies exposed to eculizumab (less than 300 pregnancy outcomes) indicate there is no increased risk of foetal malformation or foetal-neonatal toxicity. However, due to the lack of well-controlled studies, uncertainties remain. Therefore, an individual risk benefit analysis is recommended before starting and during treatment with eculizumab in pregnant women. Should such a treatment be considered necessary during pregnancy, a close maternal and foetal monitoring according to local guidelines is recommended.

Animal reproduction studies have not been conducted with eculizumab (see section 5.3).

Human IgG are known to cross the human placental barrier, and thus eculizumab may potentially cause terminal complement inhibition in the foetal circulation. Therefore, BEKEMV should be given to a pregnant woman only if clearly needed.

Breast-feeding

No effects on the breastfed new-born/infant are anticipated as limited data available suggest that eculizumab is not excreted in human breast milk. However, due to the limitations of the available data, the developmental and health benefits of breast-feeding should be considered along with the mother's clinical need for eculizumab and any potential adverse effects on the breastfed child from eculizumab or from the underlying maternal condition.

Fertility

No specific study of eculizumab on fertility has been conducted.

4.7. Effects on ability to drive and use machines

BEKEMV has no or negligible influence on the ability to drive and use machines.

4.8. Undesirable effects

Summary of the safety profile

Supportive safety data were obtained from 33 clinical studies that included 1,555 patients exposed to eculizumab in complement-mediated disease populations, including PNH, aHUS, refractory generalised myasthenia gravis (gMG) and neuromyelitis optica spectrum disorder (NMOSD). The most common adverse reaction was headache, (occurred mostly in the initial phase of dosing), and the most serious adverse reaction was meningococcal infection.

Tabulated list of adverse reactions

b Meningococcal infection includes the following group of PTs: meningococcal infection, meningococcal sepsis, meningitis meningococcal.

c ADRs identified in post marketing reports.

d Frequency cannot be estimated from the available postmarketing data.

Description of selected adverse reactions

In all clinical studies, the most serious adverse reaction was meningococcal sepsis which is a common presentation of meningococcal infections in patients treated with eculizumab (see section 4.4).

Other cases of Neisseria species have been reported including sepsis with Neisseria gonorrhoeae, Neisseria sicca/subflava, Neisseria spp unspecified.

Cases of haemolysis have been reported in the setting of missed or delayed eculizumab dose in PNH clinical trials (see also section 4.4).

Cases of thrombotic microangiopathy complication have been reported in the setting of missed or delayed eculizumab dose in aHUS clinical trials (see also section 4.4).

Paediatric population

In children and adolescent PNH patients (aged 11 years to less than 18 years) included in the paediatric PNH study M07-005, the safety profile appeared similar to that observed in adult PNH patients. The most common adverse reaction reported in paediatric patients was headache.

In paediatric aHUS patients (aged 2 months to less than 18 years) included in the aHUS studies C08-002, C08-003, C09-001r and C10-003, the safety profile appeared similar to that observed in adult aHUS patients. The safety profiles in the different paediatric subsets of age appear similar.

Elderly population

No overall differences in safety were reported between elderly (≥ 65 years) and younger refractory gMG patients (< 65 years).

Patients with other diseases

Safety data from other clinical studies

Supportive safety data were obtained in 12 completed clinical studies that included 934 patients exposed to eculizumab in other disease populations other than PNH, aHUS, refractory gMG or NMOSD. There was an un-vaccinated patient diagnosed with idiopathic membranous glomerulonephropathy who experienced meningococcal meningitis. Adverse reactions reported in patients with disease other than PNH, aHUS, refractory gMG or NMOSD were similar to those reported in patients with PNH, aHUS, refractory gMG or NMOSD (see table 1 above). No specific adverse reactions have emerged from these clinical studies.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via:
