About this study

Official title: Twelve-months Extension Study to Explore the Long-Term Safety and Efficacy of Subcutaneous Administration of GV1001 1.12 mg/Day in Patients With Progressive Supranuclear Palsy Who Completed Study GV1001-PSP-CL2-011

The study will be conducted by the Sponsor to evaluate Twelve-months Long-Term Safety and Efficacy of GV1001 (1.12 mg) administered subcutaneously as a treatment for Progressive Supranuclear Palsy(PSP). In 75 patients diagnosed with PSP Richardson(PSP-RS) or PSP-Parkinsonism (PSP-P) who Completed Study GV1001-PSP-CL2-011.

Read the detailed description

In GV1001-PSP-CL2-011 study, subjects who were in the trial group (Study Group 1(GV1001 0.56 mg/day), Study Group 2(GV1001 1.12 mg/day) is alternately administered High-dose test drug(GV1001 1.12 mg/day) and placebo once a week from Ex-Visit 1(Visit 16, Week 26) to Ex-Visit 5(Visit 20, Week 30) and High-dose test drugs(GV1001 1.12 mg/day) are administered from Ex-Visit 6 (Visit 21, Week 32) to Ex-Visit 26(Visit 41, Week 72) every two weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing GV1001 1.12mg in people with Progressive Supranuclear Palsy, run by GemVax & Kael at 5 sites in South Korea.

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 3 inclusion and 3 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 21 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in South Korea. 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 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?

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?

Adverse Event (time frame: 12 months). The study lists 33 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 Nov 2025.
