Study Endpoints

Primary Endpoints

Safety and Tolerability as measured by the number of patients with Adverse Events, as well as type of AE and frequency
Baseline up to week 23 Post-treatment

Evaluation of changes in laboratory tests (hematological, chemistry), immunogenicity and physical examination

Determine safety of administering GL-ONC1 intraperitoneally by the evaluation of the number of patients experiencing Adverse Events (type, frequency, and severity)
Change from baseline over 24 hours, on days 2, 3, 4,5,6, 7 post treatment (Cycle 1) and change from baseline for Cycles 2- 4 CX/Days 1, 2, 3, 5, 8 post-treatment. Each cycle is 4 weeks and treatment will occur for a total of 4 cycles.

The safety of GL-ONC1 will be assessed by the evaluation of the type, frequency, and severity of adverse events (AEs), changes in laboratory tests (haematological, chemistry, urinary), immunogenicity and physical examination

Determine the safety and tolerability of GL-ONC1, administered intravenously to patients with advanced solid tumors.
Every 30 minutes for 2 hours after each administration of GL-ONC1, then daily until discharge and on day 8, then weekly up to day 21, then week 12 and week 24

Secondary Endpoints

Presence of Virus in Tumor
At baseline (Within 4 weeks of Treatment Day 1); 9-13 days post viral injection
Determine Initial Susceptibility of tumor to viral infection
At baseline (Within 4 weeks of Treatment Day 1)
Anti-Tumor Activity (Early Efficacy)
Change from baseline up to week 23 Post-treatment (week 23)

Frequently asked questions about GL-ONC1

What is GL-ONC1 used for?

GL-ONC1 is an investigational oncolytic virus being studied for the treatment of advanced solid tumors, peritoneal carcinomatosis, and cancer of the head and neck. It is a monoclonal antibody modality, though it functions as an oncolytic virus. It is currently in Phase 1 clinical development and is not yet approved by regulatory authorities.

Who makes GL-ONC1?

GL-ONC1 is being developed by Genelux Corporation, a biopharmaceutical company. The company's stock ticker is GNLX. Genelux is conducting clinical trials to evaluate the safety and efficacy of GL-ONC1 in various oncology indications.

What phase is GL-ONC1 in?

GL-ONC1 is in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by regulatory agencies such as the FDA. All completed trials for GL-ONC1 are Phase 1 studies, and it remains in early-stage clinical testing.

What clinical trials has GL-ONC1 been in?

GL-ONC1 has been studied in three completed Phase 1 clinical trials. These include NCT00794131 for advanced solid tumors in the United Kingdom, NCT01443260 for peritoneal carcinomatosis in Germany, and NCT01584284 for head and neck cancer in the United States. All trials were uncontrolled and not randomized.

How does GL-ONC1 work?

GL-ONC1 is an oncolytic virus, specifically an attenuated vaccinia virus, that is designed to selectively infect and destroy cancer cells. While it is classified as a monoclonal antibody modality, its mechanism involves viral oncolysis, where the virus replicates within tumor cells and causes their lysis, potentially stimulating an immune response.

Is GL-ONC1 the same as an oncolytic vaccinia virus?

Yes, GL-ONC1 is an oncolytic vaccinia virus. It is an attenuated form of the vaccinia virus that has been modified to target and kill cancer cells. This mechanism is being investigated in clinical trials for multiple solid tumor types, including head and neck cancer and peritoneal carcinomatosis.
