About this study

Official title: A Single-arm, Open-label, Single-dose Study to Evaluate the Safety, Tolerability, and Efficacy of CRG003 Injection in the Treatment of Late Onset Pompe Disease

This is a single-center, single-arm, open-label, single-dose treatment clinical study to evaluate the safety, tolerability and efficacy of CRG003 injection in participants with late onset Pompe disease (LOPD), with a long-term follow-up period of 5 years.

CRG003 (BBM-G102) injection is an adeno-associated virus (AAV) gene therapy product for treating Pompe disease to stably express active GAA enzyme in the liver on a long-term basis after the injection.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CRG003 injectionGenetic

    Also called BBM-G102 injection

    The dose of CRG003 will be calculated according to the participant's weight with single intravenous infusion.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of dose limited toxicities

    Incidence of dose limited toxicities (DLTs) as determined by the safety review committee (SRC) within 12 weeks following CRG003 infusion;

    Measured: 12 weeks

  2. Incidence of adverse events and serious adverse events

    Incidence of adverse events (AEs) and serious adverse events (SAEs) within 26 weeks and 52 weeks following CRG003 infusion

    Measured: 26 weeks and 52 weeks

  3. The change of hepatic enzyme concentration

    Alkaline phosphatase (ALP)

    Measured: 26 weeks and 52 weeks

  4. Changes from baseline in liver function

    Changes from baseline in liver function [Alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT) and total bilirubin (TBIL)] within 26 weeks and 52 weeks following CRG003 infusion

    Measured: 26 weeks and 52 weeks

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing CRG003 injection in people with Pompe Disease (Late-onset), run by Huashan Hospital 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 11 inclusion and 14 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: opening soon, as of the sponsor's last update on 21 Dec 2023. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Wenhua Zhu, MD,PhD (+8621-52889999 ext. 8160, zhuwenhua@huashan.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of dose limited toxicities (time frame: 12 weeks). The study lists 4 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 21 Dec 2023.
