About this study

Official title: A Multicenter Open-Label Multi-Cohort Dose-Escalation Study to Evaluate Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Immunogenicity of GNR-051 (GENERIUM JSC, Russia) in Subjects With Solid Advanced Malignancies

It is a Phase 1 Multicenter Open-Label Multi-Cohort Dose-Escalation Study to Evaluate Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Immunogenicity of GNR-051 in Subjects with Advanced Solid Malignancies.

Read the detailed description

GNR-051 is a monoclonal antibody, targeting the Programmed Death-1 (PD-1) membrane receptor on T lymphocytes and other cells of the immune system. The anti-PD-1 antibody, preventing the binding of the PD-1 receptor with the ligands PD-L1 and PD-L2, reactivates the pool of tumor-specific cytotoxic T-lymphocytes in the tumor microenvironment and, thus, reactivates the antitumor immunity. GNR-051 is able to block the signaling molecule PD-1, which suppresses the antitumor immune response, for the treatment of cancer.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GNR-051 in people with Carcinoma, Non-Small-Cell Lung and Carcinoma, Renal Cell, run by AO GENERIUM at 12 sites in Russia.

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 7 inclusion and 33 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 17 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in Russia. 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?

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?

Maximum Tolerated Dose (MTD) (time frame: 28 Days). The study lists 8 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 Sep 2026.
