About this study

Official title: An Open-label, Multicenter, Single Ascending Dose and Multiple Ascending Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Efficacy of GB10 Intravitreal Injection in Patients With Neovascular Age-related Macular Degeneration (nAMD)

This study aims to preliminarily evaluate the efficacy and safety of GB10 intravitreal (IVT) injection for the treatment of patients with neovascular age-related macular degeneration (nAMD). It consists of two parts, single-ascending-dose escalation (SAD) and multiple-ascending-dose escalation (MAD).

In SAD, a single IVT of up to 6 doses will be administered to up to 36 treatment-naïve or previously treated patients with nAMD. If the lowest dose is considered safe without dose-limiting toxicity, escalation will proceed to the next higher dose level. At the end of SAD, the two doses that best balance efficacy and safety will be selected and entered into MAD.

Read more

In MAD, a single IVT of 2 doses will be administered to 12 treatment-naïve or previously treated patients with nAMD, who will be enrolled across the low- to high-dose levels.

After GB10 intervention, the participants will undergo tests to evaluate the PK/PD characteristics of GB10 and ocular and non-ocular safety.

Read the detailed description

This is an open-label, multicenter, dose-escalating study in patients with nAMD. The study consists of two parts: single-ascending-dose escalation (SAD) and multiple-ascending-dose escalation (MAD). It aims to evaluate the safety, tolerability, and PK/PD profile of single and multiple GB10 IVT injections in patients with nAMD, to investigate the efficacy of GB10, and to assess its immunogenicity.

In SAD, a single IVT of 6 doses (per-eye administration, the same below) will be administered to up to 36 treatment-naïve or previously treated patients with neovascular age-related macular degeneration (nAMD). Participants will be enrolled sequentially, starting with the lowest dose and progressing to the highest. The first participant of each cohort will serve as the sentinel participant. If no dose-limiting toxicities related to GB10 treatment are observed among the participants, escalation will proceed to the next higher dose level after approval from the safety review committee. Two doses, best balancing efficacy and safety, will be determined in SAD and then entered into MAD.

In MAD, a single IVT of 2 doses will be administered to 12 treatment-naïve or previously treated patients with nAMD, who will be enrolled across the low- to high-dose levels.

After GB10 intervention, the participants will undergo tests to evaluate the PK/PD characteristics of GB10 and ocular and non-ocular safety.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GB10 in people with Neovascular Age-Related Macular Degeneration (nAMD), run by Shenzhen Kexing Pharmaceutical Co., Ltd. at 6 sites 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 9 inclusion and 25 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 12 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites 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?

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 Hengxin Peng (86-0755-23018589, penghengxin@kexing.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The incidence and severity of ocular adverse events (time frame: From enrollment to the end of treatment at 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 12 Feb 2026.
