What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new drug, VIO-01 (also known as OX425), for individuals with solid tumor cancers to assess its safety and efficacy. The first part of the trial determines the safest dose when the drug is used alone or with other cancer treatments. The second part examines its effects on advanced cancers, such as ovarian cancer, with specific genetic features. Suitable candidates have advanced solid tumors, particularly those with specific genetic changes, and have not found success with other treatments. Participants will adhere to a schedule for site visits to undergo health checks and receive the drug. As a Phase 1 trial, participants will be among the first to receive this new treatment, aiding researchers in understanding its effects in humans.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. However, if you are on endocrine therapy for hormone receptor-positive breast cancer, it must be completed at least 7 days before starting the trial treatment.

Is there any evidence suggesting that VIO-01 is likely to be safe for humans?

Research shows that VIO-01 is undergoing safety testing for treating various solid tumor cancers. Early studies examine its safety when administered alone or with other cancer treatments, as well as patient tolerance.

Since this trial is in its early stages, researchers continue to collect safety data in humans. They aim to find the optimal dose that minimizes side effects. However, early preclinical research demonstrated that VIO-01 is highly effective against tumors. This finding is promising, suggesting the treatment could be effective against tumors.

For those considering trial participation, it's important to know that the primary goal at this stage is to ensure the treatment is safe and well-tolerated. This trial will help determine if VIO-01 can be safely used in people with solid tumors. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Researchers are excited about VIO-01 for recurrent cancer because it offers a novel approach compared to existing treatments. Unlike traditional chemotherapy, which targets rapidly dividing cells broadly, VIO-01 is specifically designed to work on tumors with HRRm or HRD+ mutations. This targeted approach could potentially lead to more effective treatment outcomes with fewer side effects. Additionally, VIO-01 is administered via a weekly intravenous infusion, which might provide a more consistent delivery of the drug compared to some oral medications that require daily dosing.

What evidence suggests that VIO-01 might be an effective treatment for recurrent cancer?

Research shows that VIO-01, which participants in this trial may receive, could be a promising treatment for certain cancers. Studies have found that it can trick cancer cells into not repairing themselves, enhancing its ability to fight tumors. This treatment has proven effective in various solid tumor cancers. It shows particular promise for treating ovarian cancer, even in cases without the usual genetic mutations. These early findings suggest that VIO-01 might work well when combined with other cancer treatments. ^{2 4 5 6 7}

The oncolytic adenovirus expressing variant interleukin-2 (vIL-2), known as TILT-452, significantly enhances the cancer-killing ability of natural killer (NK) cells in ovarian cancer, as demonstrated in both ex vivo co-culture experiments and in vivo studies using patient-derived xenografts in mice.

Mechanistically, the vIL-2 virus increases the levels of granzyme B in NK and CD8+ T cells, which are crucial for attacking cancer cells, while maintaining stable levels of regulatory T cells, suggesting a targeted enhancement of the immune response against ovarian cancer.
