About this study

Official title: An Open-label, Multiple Dose, Dose Escalation Study to Evaluate the Safety and Tolerability of QR-110 in Subjects With Leber's Congenital Amaurosis (LCA) Due to c.2991+1655A>G Mutation (p.Cys998X) in the CEP290 Gene

The purpose of this study is to evaluate the safety and tolerability of QR-110 administered via intravitreal injection in subjects with LCA due to the CEP290 p.Cys998X mutation.

Read the detailed description

The purpose of this study is to evaluate the safety and tolerability of QR-110 administered via intravitreal injection in subjects with LCA due to the CEP290 p.Cys998X mutation. Subjects will receive QR-110 in one eye every 3 months, for a maximum of 4 doses. Up to 3 dose levels of QR-110 will be evaluated.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing QR-110 in people with Leber's Congenital Amaurosis, run by Laboratoires Thea at 3 sites in 2 countries.

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 5 inclusion and 8 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 15 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States, Belgium. 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 combined 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.

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?

Yes. Results are posted in the registry (first posted 27 Dec 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Frequency and Severity of Ocular Adverse Events in the Treatment and Contralateral Eyes (time frame: 1 year). 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 NCT03140969, which also lists 4 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 15 Oct 2024.
