About this study

Official title: A Phase I, Multicenter, Randomized, Double-Blind, Placebo-Controlled, Ascending Single-Dose Study Of The Safety, Tolerability, And Pharmacokinetics Of Intravenous VX15/2503 In Patients With Multiple Sclerosis

The purpose of this study is to evaluate the safety and tolerability of IV administration of VX15/2503 in patients with multiple sclerosis. The escalation part of the study will determine the maximum tolerated dose (MTD) or the Maximum Administered Dose if no MTD is found.

Read the detailed description

VX15/2503-N-101 is a single ascending dose-escalation, randomized, double-blinded, placebo-controlled study to evaluate the safety and tolerability of IV-administered VX15/2503 in patients with multiple sclerosis. This will be accomplished by using a dose escalation procedure starting at a low dose of VX15/2503 and will continue based on predefined parameters until the maximum tolerated dose is identified. Patients will be randomized at a 4:1 ratio to receive VX15/2503 to placebo. The patients and the study team will be blinded to the treatment that each patient receives.

The study drug, VX15/2503, is a humanized monoclonal antibody that binds to the semaphorin 4D (SEMA4D; CD100) antigen. Experimental evidence suggest that antibody neutralization of SEMA4D may represent a new therapeutic strategy for treating multiple sclerosis.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing VX15/2503 in people with Multiple Sclerosis, run by Vaccinex Inc. at 10 sites in United States.

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 8 inclusion and 19 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 6 Feb 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in United States. 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 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?

Safety/Tolerability as determined by number of patients with adverse events (time frame: Up to 12 weeks depending on dose cohort). 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 NCT01764737, which also lists 2 linked publications.

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 6 Feb 2015.
