For one patient, the hemostatic efficacy assessment was missing. As per the statistical analysis plan, the rating by the investigator was designated as “None”.

The success rate was a rating of excellent/good, with 95% confidence intervals calculated by the Clopper Pearson Method. †

For 100% of minor bleeds, just a single infusion of fibryga was needed to achieve control

93% of bleeding episodes required a single infusion only1,3

Important Safety Information Contraindications Fibryga® is contraindicated in individuals who have manifested severe immediate hypersensitivity reactions, including anaphylaxis, to Fibryga or its components.

Adverse Reactions The most serious adverse reactions that may be observed with Fibryga are thromboembolic episodes and anaphylactic type reactions. The most common adverse reactions observed in more than one subject in clinical studies with Fibryga (> 5% of subjects) were nausea, vomiting, pyrexia (fever) and thrombocytosis.

78.7% n = 70

*Analyses that excluded 2 minor BEs showed no impact on overall hemostatic efficacy (86 of 87 [98.9%] evaluable bleeding episodes rated as treatment success by IDMEAC).

Success rate is a rating of excellent/good, with 90% confidence intervals calculated according to the Blyth–Still–Casella interval for the proportion of patients with successful hemostatic efficacy.

Phase II/Phase III Clinical Trials: Pharmacokinetics and Safety

Dosing and Convenience Dosing and Reconstitution

Pharmacokinetic (PK) Profile n

Fibryga® demonstrated a similar PK profile for fibrinogen concentration compared to an active control, achieving levels well within the recommended target range of 1 to 1.5 g/L2

Safety Profile Observed in Fibryga and Active Control Phase II and Phase III Clinical Trials n

Most common adverse effects (AEs) (>5% of subjects) were nausea, vomiting, pyrexia (fever), and thrombocytosis1-3

n

AEs were generally mild, single events1,3

n

No deaths or severe allergic reactions were reported1-4

n

No clinical evidence of neutralizing antifibrinogen antibodies1-4

FORMA-02 trial2,3 n

n

Fibryga® is a sterile, lyophilized powder for reconstitution for intravenous injection, provided in single-use bottles containing approximately 1 g fibrinogen concentrate

n

Dosing is individualized based on clinical condition of patient, location/extent of bleeding, and laboratory values – Functional fibrinogen level should be determined to calculate dosage

n

In total, 91 AEs in 19 patients (76.0%) were reported

n

Three AEs in three patients were considered possibly related to treatment: a moderate AE reported as exacerbation of a preexisting condition of peripheral ischemia due to digital microthrombi, a mild skin reaction, and a mild AE reported as peripheral phlebitis of the upper limbs, all of which resolved

n

In total, 10 AEs in 4 patients (28.6%) were reported Two AEs in one patient were considered possibly related to treatment: portal vein thrombosis (PVT) and fever (pyrexia). The PVT was rated as a serious AE (SAE) and occurred after a splenectomy for spontaneous spleen rupture. The SAE was assessed as possibly related to fibryga while taking into consideration that PVT is a regular complication of splenectomy. The SAE led to the discontinuation of the patient from the study

Please see Important Safety Information throughout.

Dose (mg/kg body weight) when fibrinogen level is known: Adults and adolescents ≥12 years of age: [Target fibrinogen level (mg/dL) - measured level (mg/dL)] 1.8 (mg/dL per mg/kg body weight) Children 0 to <12 years of age: [Target fibrinogen level (mg/dL) - measured level (mg/dL)] 1.4 (mg/dL per mg/kg body weight) Recommended target fibrinogen plasma levels: 100 mg/dL (minor bleeds); 150 mg/dL (major bleeds)

FORMA-04 trial1,4

Important Safety Information Warnings and Precautions Monitor patients for early signs of hypersensitivity or allergic reactions. If necessary, discontinue administration and institute appropriate treatment. Thrombotic events have been reported in patients receiving Fibryga®.

Treatment with human fibrinogen concentrate has been associated with thrombosis at target plasma fibrinogen levels that were below 150 mg/dL. The thrombotic risks may be greater when the target fibrinogen plasma level is 150 mg/dL. Weigh the benefits of administration versus the risks of thrombosis.

Fibryga is made from pooled human plasma. Products made from human plasma may contain infectious agents, e.g., viruses and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent.
