About this study

Official title: A Randomized, Double-blind, Placebo-controlled Study of Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Ascending Single Intravenous and Subcutaneous Doses of GZ402668 in Men and Women With Progressive Multiple Sclerosis

Primary Objective:

To assess the safety and tolerability of GZ402668 after ascending single intravenous (IV) and subcutaneous (SC) doses in men and women with progressive multiple sclerosis.

Secondary Objectives:

To assess the following in men and women with progressive multiple sclerosis:

  • The pharmacokinetic (PK) parameters of GZ402668 after ascending single IV doses.
  • The pharmacodynamics (PD) of GZ402668 after ascending single IV doses.
  • The PK parameters of GZ402668 after ascending single SC doses.
  • The PD of GZ402668 after ascending single SC doses.
Read the detailed description

The total study duration from screening for a patient can be approximately up to 8 weeks.

Upon completion of this trial, patients treated with GZ402668 will be required to enroll in a 4 year safety follow-up study for continued safety observation.

Being tested
GZ402668, placebo, acyclovir
Medical subject headings

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GZ402668 and acyclovir in people with Progressive Multiple Sclerosis, run by Genzyme, a Sanofi Company at 1 site in Germany.

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 6 inclusion and 26 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: finished, as of the sponsor's last update on 13 Apr 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. 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. Some participants in this study may receive a placebo. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Number of participants with treatment emergent adverse events (time frame: 4 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 NCT02282826, 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 13 Apr 2016.
