About this study

Official title: A Single/Multiple Dose Escalation, Open-Labeled, Phase I Clinical Study to Assess the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of FB1001 in Patients With Acute Optic Neuropathy

This study is designed for single-center, open-label, dose escalation phase I trial to evaluate the safety and tolerability of a single/multiple intravitreal injection of FB1001 in patients with APACG(Acute Primary Angle-Closure Glaucoma) or NAION(Nonarteritic Anterior Ischemic Optic Neuropathy).

Read the detailed description

After acute attack of APACG or NAION, patients are going to experience progression of visual field or visual acuity defects, even after IOP or inflammation control by diverse treatments. FB1001 is a recombinant humanized monoclonal antibody that protects and repairs the optic nerve, thereby delaying the progression of glaucoma and NAION. The main purpose of this study is to evaluate the safety and tolerability of FB1001 by single/multiple intravitreal injections to Acute Optic Neuropathy Patients. Pharmacokinetic profile through blood/Aqueous will be investigated and preliminary efficacy will be explored if possible. SAD(Single Ascending Dose) will consist of a maximum of 5 cohorts and each cohort will enroll 3 to 6 eligible patients. MAD(Multiple Ascending Dose) will consist of a maximum of 3 cohorts and each cohort will enroll 8 eligible patients. For each participant, the study will last up to about 12 weeks for SAD part, and 24 weeks for MAD part.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing FB1001 in people with Optic Neuropathy and NAION - Non-Arteritic Ischemic Optic Neuropathy, run by Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine 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 12 inclusion and 36 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: status not confirmed, as of the sponsor's last update on 17 Jul 2024. 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?

Results are not available in the source record.

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

Contact Xiaodong MD Sun, PhD (021-36126059, drsunxiaodong@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

SAD phase: DLTs incidence (time frame: within 28 days after dosing). The study lists 3 primary outcomes in all. 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 17 Jul 2024.
