About this study

Official title: A Phase I Clinical Trial of BAT4406F Injection on the Safety, Tolerability, and Pharmacokinetics in Patients With Neuromyelitis Optica Spectrum Disorders

This study is a phase I clinical study of the safety, tolerability, and pharmacokinetics of BAT4406F injection in patients with neuromyelitis optica spectrum disorders.

Read the detailed description

This is a Phase 1, open-label, dose-escalation study in NMOSD patients in which subjects will receive BAT4406F injection via intravenous infusion. A 3 + 3 design will be utilized to define a maximum tolerated dose (MTD). The overall objective is to assess the safety, tolerability, and pharmacokinetics of BAT4406F injection in NMOSD patients.

Being tested
BAT4406F
Medical subject headings

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BAT4406F in people with Neuromyelitis Optica Spectrum Disorders, run by Bio-Thera Solutions at 1 site in China.

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 7 inclusion and 12 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 10 Jul 2025. 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 China. 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?

Dose-limiting toxicity(DLT) (time frame: 4weeks). The study lists 7 primary outcomes in all. 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 NCT04146285, 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 10 Jul 2025.
