6. Adverse Reactions/Side Effects

The most common adverse reactions reported in clinical trials (≥1%), were headache, pain in the extremities, injection site pain, and increase in fibrin D dimer levels.

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

During clinical development, TRETTEN was administered to 77 subjects with congenital factor XIII A-subunit deficiency (3:2, male: female ratio) for a total of 1990 doses. Fifty subjects (65%) were between the ages of 18 and 77 years (received 1338 doses), 21 subjects (27%) were between the ages of 6 and less than 18 years old (received 560 doses), and 6 subjects (8%) were less than 6 years old (received 92 doses). Subjects were exposed for up to 4.5 years.

Of the 77 subjects, 68 received 1979 monthly doses of 35 IU/kg of TRETTEN for routine prophylaxis of bleeding. Eleven single doses of TRETTEN have been administered to nine subjects for pharmacokinetic investigations.

The adverse drug reactions reported included headache, pain in the extremities, pain at the injection site, and increase in fibrin D dimer levels (without evidence of thromboembolic events).

Immunogenicity

The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to TRETTEN with the incidence of antibodies to other products may be misleading.

Transient non-neutralizing antibodies were seen in one out of 50 healthy subjects after one dose, four out of 77 trial subjects (age < 18 years) with congenital factor XIII A-subunit deficiency after one or two doses (3 discontinued from the trial), and in one subject (age < 18 years) in a post marketing safety study after 3.5 years of treatment. In two subjects, the non-neutralizing antibodies disappeared after continued treatment with TRETTEN. In all cases, the non-neutralizing antibodies were found to be of no clinical significance. No subjects developed neutralizing antibodies (inhibitors) against TRETTEN during clinical trials.

8. Use In Specific Populations

8.2 Lactation

Risk Summary

There is no information regarding the presence of TRETTEN in human milk, the effect on the breastfed infant, and the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for TRETTEN and any potential adverse effects on the breastfed infant from TRETTEN or from the underlying maternal condition.

11. Tretten Description

TRETTEN, Coagulation Factor XIII A-Subunit (Recombinant), is a recombinant human factor XIII-A2 homodimer composed of two factor XIII (FXIII) A-subunits. The FXIII A-subunit is a 731 amino acid chain with an acetylated N-terminal serine. When FXIII is activated by thrombin, a 37 amino acid peptide is cleaved from the N-terminus of the A‑subunit.

TRETTEN is manufactured as an intracellular, soluble protein in yeast (Saccharomyces cerevisiae) production strain containing the episomal expression vector, pD16. It is subsequently isolated by homogenization of cells and purification by several chromatography steps, including hydrophobic interaction and ion exchange chromatography. No human or animal derived products are used in the manufacturing process.

TRETTEN is supplied as a sterile, white lyophilized powder in a single-dose vial. Table 1 and Table 2 list the vial content of reconstituted TRETTEN and the diluent, respectively.

12. Tretten - Clinical Pharmacology

12.1 Mechanism of Action

FXIII is the terminal enzyme in the blood coagulation cascade. When activated by thrombin at the site of vessel wall injury, FXIII plays an important role in the maintenance of hemostasis through cross-linking of fibrin and other proteins in the fibrin clot.

In plasma, FXIII circulates as a heterotetramer [A2B2] composed of two FXIII A-subunits and two FXIII B-subunits held together by strong non-covalent interactions. The FXIII A is the catalytic subunit and FXIII B-subunit acts as carrier molecule for the FXIII A-subunit in circulation, and is present in excess in plasma. When FXIII A-subunit is bound to FXIII B-subunit [A2B2] the half-life of the FXIII A-subunit [A2] is prolonged. FXIII is a pro-enzyme (protransglutaminase), which is activated by thrombin in the presence of Ca2+. The enzymatic activity resides with the FXIII A-subunit. Upon activation, the FXIII A‑subunit dissociates from the FXIII B-subunit and thereby exposes the active site of the FXIII A-subunit. The active transglutaminase cross-links fibrin and other proteins resulting in increased mechanical strength and resistance to fibrinolysis of the fibrin clot and contributes to enhance platelet and clot adhesion to injured tissue.

Coagulation Factor XIII A-Subunit (Recombinant) is a protransglutaminase (rFXIII [rA2] homodimer) and binds to free human FXIII B-subunit resulting in a heterotetramer [rA2B2] with a similar half-life to [A2B2]. rFXIII has been shown to be activated by thrombin in the presence of Ca2+. Activated rFXIII has been shown in dose-dependent manner to increase mechanical strength of fibrin clots, retard fibrinolysis, and rFXIII has been shown to enhance platelet adhesion to the site of injury. After combining with available plasma B-subunits, Coagulation Factor XIII A-subunit (Recombinant) has been shown to have the same pharmacodynamic properties in plasma as endogenous FXIII.

12.3 Pharmacokinetics

Steady State in Subjects with Congenital Factor XIII Deficiency

In 23 subjects with congenital FXIII A-subunit deficiency on prophylaxis, the pharmacokinetics of rFXIII were evaluated over a dosing interval of 28 days during steady state.

The pharmacokinetic parameters based on steady state baseline adjusted FXIII activity (Berichrom assay) values are shown in Table 3.

Pediatric (Ages 1 to < 6 Years Old)

In a pharmacokinetic trial six children with congenital FXIII A-subunit deficiency on prophylaxis treatment were administered a single intravenous dose of 35 IU/kg. The pharmacokinetic parameters based on baseline adjusted FXIII activity (Berichrom assay) values are shown in Table 4. No dose adjustment is needed for pediatric patients as there is no influence of age on the pharmacokinetics of TRETTEN.

14. Clinical Studies

To establish the efficacy of TRETTEN for the prevention of bleeding in patients with congenital FXIII A-subunit deficiency, a multi-center, open-label, non-controlled trial was conducted for 52 weeks in forty-one (41) subjects ≥ 6 years. All subjects received monthly doses of TRETTEN at 35 IU/kg. Bleeding episodes that required treatment with a FXIII-containing product were observed to evaluate the efficacy of monthly replacement therapy with TRETTEN on prevention of bleeding episodes.

Subjects with congenital FXIII A-subunit deficiency confirmed by genotyping were included. Subjects who before entering the trial had received regular replacement therapy were to have initiated regular replacement therapy at least 6 months prior to screening and were to have a documented history of at least one treatment-requiring bleeding episode before initiation of regular replacement therapy or a documented family history of FXIII congenital deficiency. Subjects who before entering the trial had only received on-demand treatment were to have a documented history of at least two treatment-requiring bleeding episodes within 12 months of the screening visit. Severe bleeders as defined by a documented history of ≥2 treatment requiring bleedings per year during regular FXIII replacement therapy were excluded.

During the prophylaxis treatment period with TRETTEN (434 subject months), five bleeding episodes treated with FXIII-containing products were observed in four subjects. All five were associated with trauma. When calculated for all 41 subjects, this translated into a mean annual rate of bleeding episodes that required treatment of 0.14 [95% CI:0.058- 0.332] per subject year, which was statistically significantly lower than the historic bleeding rate of 1.68 per subject year for on-demand treatment. The age-adjusted rate of bleeding episodes that required treatment during the TRETTEN treatment period was 0.05 [95% CI: 0.0094 - 0.2501] per subject year with a model-based estimate corresponding to the mean age of 26.4 years. The mean annual bleeding rate in subjects below 18 years of age was higher compared to that in adults (0.362 versus 0.040 bleeds/subject/year). Table 5 below lists the estimated bleeding rates by age.

Thirty-four (34) of the 41 subjects and an additional 21 new subjects were enrolled in an ongoing second trial. During a total treatment period of 107.5 subject years (mean of 1.95 years per subject), 5 subjects experienced 6 bleeds that required treatment with a FXIII-containing product. The mean annual rate of bleeding episodes that required treatment was determined to be 0.056 per subject year. The age-adjusted rate of bleeding episodes that required treatment during the TRETTEN treatment period was 0.022 per subject year [95% CI:0.0045; 0.1023] with a model-based estimate corresponding to a mean age of 29.5 years. The annual mean bleeding rate in subjects below age 18 was higher compared to that in adults (0.127 versus 0.026 bleeds/subject/year) with some overlap of the respective 95% confidence intervals.
