Pharmacodynamics.
Mechanism of action

Turoctocog alfa pegol is a purified recombinant human factor VIII (rFVIII) with a polyethylene glycol (PEG) molecule of 40 kDa size covalently conjugated to the protein. PEG is attached to the O-linked glycan in the truncated B-domain of rFVIII (turoctocog alfa). The mechanism of action of turoctocog alfa pegol is based on replacing the deficient or missing factor VIII in patients with hemophilia A.

When turoctocog alfa pegol is activated by thrombin at the site of injury, the B-domain containing the PEG fragment and the a3-region are separated, resulting in the formation of activated recombinant factor VIII (rFVIIIa), which is structurally similar to native factor VIIIa.

The factor VIII complex with von Willebrand factor consists of two molecules (factor VIII and von Willebrand factor), which have different physiological functions. When the preparation is administered to a patient with hemophilia, factor VIII binds to von Willebrand factor in the bloodstream. Activated factor VIII acts as a cofactor for activated factor IX, accelerating the conversion of factor X to activated factor X.

Activated factor X converts prothrombin to thrombin. Then thrombin converts fibrinogen to fibrin, after which a clot can form. Hemophilia A is a hereditary, sex-linked coagulation disorder due to reduced levels of factor VIII:C, leading to profuse bleeding into joints, muscles, or internal organs, either spontaneously or due to accidental trauma or surgical intervention. Through replacement therapy with factor VIII, factor VIII levels in plasma are increased, thereby enabling temporary correction of the deficiency and counteracting the tendency to bleed.

Clinical efficacy in prevention and treatment of bleeding episodes

The clinical efficacy of Esperoct in prevention and treatment of bleeding was studied in five multicenter prospective clinical trials involving 270 patients with severe hemophilia A who had previously received treatment.

Prevention in adults/children aged 12 years and older

The efficacy of Esperoct for prevention and treatment of bleeding was evaluated in an open-label, uncontrolled study in adult patients and children aged 12 years and older with severe hemophilia A. The preventive effect of Esperoct was demonstrated at a dose of 50 IU/kg every 4 days or every 3-4 days (twice a week) in 175 patients. The mean annual bleeding rate (ABR) in adults and children aged 12 years and older who received Esperoct was 1.18 (interquartile range (IQR): 0.00; 4.25), while the ABR for spontaneous events was 0.00 (IQR: 0.00; 1.82), for trauma-related events was 0.00 (IQR: 0.00; 1.74), and the ABR in joints was 0.85 (IQR: 0.00; 2.84). When imputing missing data for patients who discontinued their participation in the study, the calculated mean ABR for all bleeding episodes was 3.70 (95% CI: 2.94; 4.66). Of the 175 adults/children aged 12 years and older who received preventive treatment, 70 (40%) patients had no bleeding episodes. The mean annual consumption of the medicinal product for prevention was 4,641 IU/kg.

Note that the data on annual bleeding rate (ABR) obtained with different factor concentrates and in different clinical trials are not comparable.

Adults/children aged 12 years and older with a low bleeding frequency of 0-2 episodes over the last 6 months and who received at least 50 doses of Esperoct were eligible for randomization into preventive treatment groups with either 75 IU/kg every 7 days or 50 IU/kg every 4 days. In total, 55 of 120 patients who met the study criteria agreed to be randomized into groups (17 patients to the 75 IU/kg every 4 days group and 38 patients to the every 7 days group). The ABR in randomized patients was 1.77 (0.59; 5.32) with every 4-day dosing and 3.57 (2.13; 6.00) with weekly prophylaxis. During the randomized study phase, nine of these patients returned to every 4-day prophylaxis. Overall, considering all parts of the extension study, 31 of 61 patients who received every 7-day prophylaxis returned to every 4-day dosing.

Prevention in children under 12 years of age

The use of Esperoct in children under 12 years of age is not recommended (see section "Children").

The efficacy and safety of Esperoct for prevention of bleeding were evaluated in an open-label, single-arm study in 68 children under 12 years of age with severe hemophilia A.

The preventive effect of Esperoct was demonstrated at a dose of 60 IU/kg (50-75 IU/kg) twice a week. The median and calculated mean annual bleeding rate in children under 12 years of age who received Esperoct twice a week were 1.95 and 2.13, respectively (95% CI: 1.48; 3.06), while the ABR for spontaneous events was 0.00 and 0.58 (95% CI: 0.24; 1.40), for trauma-related bleeding was 0.00 and 1.52 (95% CI: 1.07; 2.17), and the ABR in joints was 0.00 and 1.03 (95% CI: 0.59; 1.81), respectively. Of the 68 children under 12 years of age who received preventive treatment, 29 patients (42.6%) had no bleeding episodes. The mean annual consumption of the medicinal product for prevention was 6,475 IU/kg.

Prevention in previously untreated patients (PUPs) (children under 6 years of age)

The use of Esperoct in children under 12 years of age is not recommended (see section "Children").

The efficacy and safety of Esperoct were evaluated in a multinational, non-randomized, open-label Phase 3 study. Primary prophylaxis (on-demand treatment for bleeding episodes and/or dosing at >1 week intervals until the patient reached 20 days of exposure (DE) or 24 months of age) and preventive treatment of bleeding were evaluated in 81 previously untreated patients under 6 years of age with severe hemophilia A. Of the 81 patients, 55 patients started primary prophylaxis, and 42 of these patients then switched to preventive treatment. In total, 69 patients received preventive treatment at a dose of 60 IU/kg (50-75 IU/kg) twice a week.

The preventive effect of Esperoct in previously untreated children under 6 years of age with severe hemophilia A was demonstrated with a median and calculated mean annual bleeding rate of 1.35 and 2.27, respectively (95% CI: 1.71; 3.01).

Note that the data on annual bleeding rate (ABR) obtained with different factor concentrates and in different clinical trials are not comparable. The success rate of hemostatic response in treating bleeding episodes in 69 previously untreated patients under 6 years of age who received preventive treatment was 92.5%. The mean annual consumption for 69 previously untreated patients who received preventive treatment was 5,395 IU/kg.

During the study, 56 adverse events were reported in 43 of 81 patients, and a total of 80 serious adverse events were reported in 48 patients after administration of Esperoct.

In 31 of 59 previously untreated patients without inhibitors, a temporary decrease in incremental recovery (IR) of factor VIII was observed after exposure to Esperoct. There were 17 previously untreated patients with consecutive measurements of decreased IR, all of whom had anti-PEG IgG antibodies. A link between anti-PEG antibodies and low IR cannot be ruled out.

Clinical efficacy of Esperoct in treating bleeding episodes and on-demand use

The clinical efficacy of Esperoct in treating bleeding episodes has been demonstrated in patients of all age groups.

In the majority of cases, bleeding treated with Esperoct was of mild/moderate severity.

The overall success rate of bleeding treatment was 87.7% and 94.4% of all bleeding episodes treated with 1-2 injections.

In 12 patients aged 18 years and older who received on-demand treatment, 1,126 bleeding episodes were treated with a mean dose of 38.1 IU/kg at a mean annual consumption of 1,457 IU/kg. Of these 1,126 bleeding episodes, 86.9% were effectively treated with one injection, and 96.8% with 1-2 injections of Esperoct.

Clinical efficacy of Esperoct in perioperative use

Esperoct was effective in maintaining hemostasis during major surgical procedures, with a success rate of 95.6% in all major surgeries performed (in 43 of 45 cases, efficacy was rated as "excellent" or "good").

Pharmacokinetics.

In total, 129 pharmacokinetic (PK) profiles were evaluated after single administration of Esperoct in 86 patients (including 24 pediatric patients aged 0-12 years).

All pharmacokinetic studies of Esperoct were conducted in patients with severe hemophilia A (factor VIII level <1%) who had previously received treatment. Patients received a single dose of 50 IU/kg, and blood samples were taken for analysis before administration and at multiple time points over 96 hours after administration.

In adult patients, the half-life of Esperoct was 1.6 times longer than that of unmodified factor VIII concentrates.

Pharmacokinetic parameters

In total, 108 pharmacokinetic profiles were evaluated after single administration of Esperoct at a dose of 50 IU/kg in 69 patients. The pharmacokinetic parameters of Esperoct after single administration were comparable in young children (aged 0-6 years) and older children (aged 6-12 years), as well as in adolescents (aged 12-17 years) and adults (aged 18 years and older).

As expected, in children under 12 years of age, the increase in recovery parameters was lower, while the clearance adjusted for body weight was higher. In general, a trend towards increased recovery and decreased clearance (mL/h/kg) with age was observed. This is consistent with the fact that in children under 12 years of age, the volume of distribution per kilogram of body weight is higher than in adults (Table 1).

The pharmacokinetic parameters of Esperoct after single administration, determined after 28 weeks of preventive treatment, were consistent with the initial pharmacokinetic parameters.

Table 1 shows the pharmacokinetic parameters of Esperoct after single administration. The use of Esperoct in children under 12 years of age is not indicated.

Special warnings and precautions for use.

Monitoring

During treatment, it is recommended to regularly determine factor VIII activity levels to adjust the dosing regimen of Esperoct. In different patients, the response to factor VIII may vary, resulting in different half-life and recovery parameters. For patients with insufficient or excessive body weight, dose adjustment based on body weight may be necessary. Especially during major surgical procedures, it is necessary to monitor the replacement therapy with factor VIII by determining factor VIII activity in plasma.

Factor VIII activity in Esperoct can be determined by standard quantitative assays for factor VIII - chromogenic assay and one-stage clotting assay. When using the one-stage clotting assay, which is based on determining the activated partial thromboplastin time (aPTT), the results of factor VIII activity in patient plasma samples may significantly depend on both the type of aPTT reagent and the reference standard used in the assay.

When using the one-stage clotting assay, it is recommended to avoid using certain silicon-based reagents, as they may cause underestimation of results. Additionally, there may be significant discrepancies between the results of one-stage clotting assays based on aPTT determination and chromogenic assays according to the European Pharmacopoeia. This is particularly important when changing the analytical laboratory and/or reagents for the assay.

Dosing

Doses, dosing intervals, and duration of replacement therapy depend on the severity of factor VIII deficiency, the location and severity of bleeding, the target factor VIII activity level, and the patient's clinical condition. The amount of factor VIII administered is expressed in international units (IU), which are related to the WHO standard for factor VIII concentrates. Factor VIII activity in plasma is expressed as a percentage (relative to normal human plasma) or in international units per deciliter (relative to the current international standard for factor VIII in human plasma).

One international unit (IU) of factor VIII activity is equivalent to the amount of factor VIII in 1 mL of human plasma.

Treatment on demand and treatment of bleeding episodes

The calculation of the required dose of factor VIII is based on empirical data, which indicate that one international unit (IU) of factor VIII per kilogram of body weight increases factor VIII activity in plasma by 2 IU/dL.

The required dose is determined by the following formula:

Required number of units (IU) = body weight (kg) × desired increase in factor VIII level (%) (IU/dL) × 0.5 (IU/kg per IU/dL).

The required dose and frequency of administration should always be adjusted based on clinical efficacy in each individual patient.

Recommendations for dosing Esperoct for treatment on demand and treatment of bleeding episodes are shown in Table 2. Factor VIII activity levels should be maintained at or above the specified levels in plasma (in IU/dL or % of normal). When treating bleeding, the maximum single dose of Esperoct is 75 IU/kg, and the maximum total dose is 200 IU/kg/24 hours.

Bleeding severityRequired factor VIII level (IU/dL or % of normal)aDosing frequency (hours)Duration of therapy
MildEarly hemarthrosis, mild bleeding into muscles or oral cavity20-4012-24Until bleeding stops
ModerateMore extensive hemarthrosis, bleeding into muscles, hematoma30-6012-24Until bleeding stops
Severe or life-threatening bleeding60-1008-24Until the threat is eliminated

a The required dose is determined by the following formula:

Required number of units (IU) = body weight (kg) × desired increase in factor VIII level (%) (IU/dL) × 0.5 (IU/kg per IU/dL).

Perioperative use

The dose and dosing interval of Esperoct during surgical procedures depend on the surgical procedure and local practice. The maximum single dose of Esperoct is 75 IU/kg, and the maximum total dose is 200 IU/kg/24 hours.

The frequency and duration of administration should always be adjusted based on clinical response in each individual patient.

Table 3 shows general recommendations for dosing Esperoct during perioperative use. Note that factor VIII activity should be maintained at or above the target range.

Type of surgical procedureRequired factor VIII level (IU/dL or % of normal)aDosing frequency (hours)Duration of therapy
Minor surgical procedure (including tooth extraction)30-60Within 1 hour before surgery. If necessary, repeat after 24 hours.Single or repeated injection every 24 hours for at least 1 day, until healing is achieved.
Major surgical procedure80-100 (before and after surgery)Within 1 hour before surgery, and then every 8-24 hours to maintain factor VIII activity within the target range.Repeat the injection every 8-24 hours as necessary for acceptable wound healing. Consider continuing therapy for an additional 7 days to maintain factor VIII activity at 30-60% (IU/dL).

a The required dose is determined by the following formula:

Required number of units (IU) = body weight (kg) × desired increase in factor VIII level (%) (IU/dL) × 0.5 (IU/kg per IU/dL).

Prevention

The recommended dose of Esperoct is 50 IU/kg every 4 days.

Dose adjustments and interval adjustments may be considered based on individual factor VIII levels and bleeding tendency in each patient.

Children

The dose for children (aged 12 years and older) is the same as for adults. For children under 12 years of age, the safety of long-term use has not been established (see section "Pharmacodynamics").

Adverse reactions.

Summary of safety profile

Rarely, hypersensitivity or allergic reactions (including angioedema, burning and stinging at the injection site, chills, flushing, generalized urticaria, headache, allergic rash, hypotension, somnolence, nausea, agitation, tachycardia, chest tightness, paresthesia, vomiting, wheezing) have been observed, which in some cases may progress to severe anaphylaxis (including shock).

Very rarely, the formation of antibodies to hamster proteins with corresponding hypersensitivity reactions has been observed.

Description of individual adverse reactions
Formation of factor VIII inhibitors

One confirmed case of factor VIII inhibitor formation was reported during preventive treatment with Esperoct in an 18-year-old patient who had previously received treatment.

The patient had an intron 22 inversion in the factor VIII gene and a high risk of factor VIII inhibitor formation.

There is no evidence of an increased risk of factor VIII inhibitor formation with Esperoct compared to other factor VIII products.

Formation of antibodies to the medicinal product

One case of persistent antibodies to the medicinal product was reported, which coincided in time with the confirmed case of factor VIII inhibitor formation (see section on factor VIII inhibitors).

In three patients, anti-Esperoct antibody test results were temporarily positive after administration of Esperoct, but no correlation with adverse reactions was found.

Anti-PEG antibodies

During the clinical trial program, 32 patients had anti-PEG antibodies before administration of Esperoct.

In 20 of 32 patients, the anti-PEG antibody test result was negative after administration of Esperoct.

In 11 patients, a temporary low titer of anti-PEG antibodies was detected.

No correlation with adverse reactions was found.

According to post-marketing reports, the formation of anti-PEG antibodies has also been observed during the transition to Esperoct.

In some patients, anti-PEG antibodies may have been associated with lower-than-expected factor VIII activity levels.

Children

No differences in the safety profile were observed in children who had previously received treatment (aged 12-18 years) compared to adult patients.

Adverse reactions

Reporting suspected adverse reactions after authorization of the medicinal product is important.
