About this study

Official title: Post-marketing Observational Study on the Safety and Efficacy of Fibryga in Congenital Fibrinogen Deficiency

Open-label, Uncontrolled, Multicenter Observational Study on the Safety and Efficacy of Fibryga in Congenital Fibrinogen Deficiency

Read the detailed description

There is a need to increase the body of data on treatment effectiveness and safety in the ultra-rare setting of congenital fibrinogen deficiency. Real-world evidence (RWE) derived from non-interventional studies can describe product utilization, demonstrate value, and facilitate benefit-risk assessments; RWE can only be fully assessed once a product is launched and used in a real-life setting.

This post-marketing, observational study is designed to collect information concerning safety, efficacy, and outcomes of Fibryga administration in routine clinical use in patients of any age with congenital afibrinogenemia or hypofibrinogenemia. Documentation of the administration of Fibryga in clinical practice for the treatment of both minor and major bleeding events (BEs) will not only enhance the knowledge on the efficacy and safety profile of Fibryga, but will also gather information that cannot be obtained in the same way in controlled clinical studies. These observational data will support the safety and efficacy data generated with Fibryga in good clinical practice (GCP) clinical studies, providing benefit for both physicians and patients.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The incidence of thromboembolic adverse drug reactions (ADRs)

    The incidence of thromboembolic ADRs in patients receiving Fibryga for on-demand treatment of bleeding, including major bleeding, will be documented

    Measured: Day 0-28

Secondary outcomes (4)
  1. Hemostatic efficacy of Fibryga for all bleeding events (BEs) collected in the study will be assessed by the investigator using a 4-point hemostatic efficacy scale

    The hemostatic efficacy of Fibryga for all BEs collected in the study will be assessed by the investigator using a 4-point hemostatic efficacy scale including the four items: 'excellent,' 'good,' moderate,' and 'none'. These data will be transformed into a dichotomous result, with 'treatment success-yes' defined as a rating of 'excellent' or 'good' and 'treatment success-no' defined as a rating of 'moderate' or 'none'.

    Measured: Within 2-24 hours following treatment of BEs

  2. Dosage of Fibryga

    Fibryga will be individually dosed as per the locally approved package insert. Actual dosage administered will be documented

    Measured: Within 2-24 hours following treatment of BEs

  3. Duration of BEs

    Details of BE duration will be documented

    Measured: Within 2-24 hours following treatment of BEs

  4. Incidence of treatment-emergent adverse events (safety)

    All ADRs in patients receiving Fibryga for on-demand treatment of BEs, including major BEs, will be documented

    Measured: Day 0-28

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted4 Jan 2019
  2. Study start28 Jan 2021
  3. Primary completion14 May 2025
  4. Study completion14 May 2025

Why it stopped: FORMA-07 was initiated as a requirement imposed by the U.S. FDA as part of Octapharma's regulatory obligations. After approving Fibryga for treatment of acquired fibrinogen deficiency in 2024, FDA has agreed that the study may now be discontinued.

Questions about this trial

What is this clinical trial studying?

An observational study of Congenital Fibrinogen Deficiency, run by Octapharma at 4 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 24 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Germany, Czechia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: FORMA-07 was initiated as a requirement imposed by the U.S. FDA as part of Octapharma's regulatory obligations. After approving Fibryga for treatment of acquired fibrinogen deficiency in 2024, FDA has agreed that the study may now be discontinued.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The incidence of thromboembolic adverse drug reactions (ADRs) (time frame: Day 0-28). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jun 2025; AzTrials last refreshed its copy on 8 Nov 2026.
