About this study

Official title: A Long-Term International, Extension of Study GNC-003 With GNbAC1 in Patients With Relapsing Remitting Multiple Sclerosis

The humanised IgG4 monoclonal antibody GNbAC1 targets the envelope protein (Env) of the human endogenous multiple sclerosis-associated retrovirus (HERV-W MSRV), which may play a critical role in multiple sclerosis.

The study assesses the long-term safety of GNbAC1 in patients with RRMS and the long-term efficacy of GNbAC1 in terms of MRI outcomes, relapse rate, disability and disease progression.

What is being measured

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

  1. Long term safety of GNbAC1

    The main parameters evaluated to assess the long term safety will be:

    AE and SAE, clinical safety laboratory, IgG4 dosing, vital signs, physical examination, ECGs, Anti-drug antibody and C-SSRS scale

    Measured: 96 Weeks

Secondary outcomes (4)
  1. Long term efficacy of GNbAC1 in terms of MRI outcomes

    Measured: 96 Weeks

  2. Long term efficacy of GNbAC1 in terms of relapse rate

    Measured: 96 Weeks

  3. Long term efficacy of GNbAC1 in terms of disability

    Measured: 96 Weeks

  4. Long term efficacy of GNbAC1 in terms of disease progression

    Measured: 96 Weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing GNbAC1 Monoclonal Antibody in people with Multiple Sclerosis, Relapsing-Remitting, run by GeNeuro SA at 12 sites in 12 countries.

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

Who may be eligible to take part?

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 20 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in Bulgaria, Croatia, Czechia, Estonia, Germany and 7 more countries. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Based on R\&D strategic reasons, our co-development Partner financing the study disengaged from the development of GNbAC1.). 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?

Long term safety of GNbAC1 (time frame: 96 Weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03239860, which also lists 1 linked publication.

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 20 Oct 2020.
