About this study

Official title: An Open Multicenter Study of the Safety, Tolerability, and Pharmacokinetics of Different Doses of Stimotimagene Copolymerplasmid at Patients With Advanced-stage Solid Tumors With Cymeven® (Ganciclovir) Infusions

The purpose of this study is to evaluate the safety and tolerability of different doses and administration regimens of Stimotimagene copolymerplasmid in patients with histologically confirmed diagnosis of solid tumor and/or its metastases.

Read the detailed description

Stimotimagene copolymerplasmid is an anti-tumor gene therapy drug, contains super-coiled plasmid DNA encapsulated in polycationic envelope (PPT: polyethyleneimine (PEI) - polyethylene glycol (PEG) - TAT peptide). The plasmid encodes two therapeutic genes: herpes simplex virus thymidine kinase (HSVtk) and human granulocyte-macrophage colony-stimulating factor (hGM-CSF). HSVtk converts the prodrug ganciclovir to a toxin in cells that have been transfected by Stimotimagene copolymerplasmid, GM-CSF stimulates proliferation and differentiation of antigen-presenting cells.

Stimotimagene copolymerplasmid therapy is two-staged: (1) intratumoral injection of Stimotimagene copolymerplasmid, (2) intravenous administration of ganciclovir (Cimeven®) This is the first-in-human study of Stimotimagene copolymerplasmid which will be conducted in three arms. In this study dose escalation (Arm1) and number of drug administrations (Arms 2 and 3) will be explored. All study parts will investigate the safety, tolerability and pharmacokinetic profile of Stimotimagene copolymerplasmid.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Stimotimagene copolymerplasmid and Ganciclovir in people with Sarcoma and Melanoma, run by Gene Surgery LLC at 4 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 18 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: finished, as of the sponsor's last update on 1 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 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?

Safety (Presence/absence of dose-limiting toxicities (DLTs)) (time frame: Through study completion, an average of 1 year). The study lists 5 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 1 Jul 2024.
