What side effects are associated with this type of intervention?

Common side effects of oncolytic virus therapies, such as ASP1012, include flu-like symptoms (fever, chills, fatigue, muscle aches), injection site reactions, and nausea. More severe immune-related adverse events can occur, such as inflammation of organs (colitis, pneumonitis). When combined with immunotherapies, additional side effects may include skin rashes, diarrhea, and endocrine disorders due to the activation of the immune system.

What prior FDA approvals exist?

The FDA has approved several treatments for solid tumors that leverage the immune system to target cancer cells. One notable example is T-VEC (talimogene laherparepvec), an oncolytic virus approved for the treatment of melanoma. T-VEC works similarly to ASP1012 by selectively infecting and killing cancer cells while stimulating an immune response against the tumor. Additionally, immune checkpoint inhibitors such as pembrolizumab and nivolumab have been approved for various solid tumors, enhancing the body's immune response to cancer cells. These treatments represent significant advancements in cancer therapy by utilizing the body's immune system to combat malignancies.

What other types of research exist?

Promising novel alternatives to ASP1012 for solid tumor patients include: 1) Talimogene laherparepvec (T-VEC), an oncolytic virus approved for melanoma that may have potential in other solid tumors. 2) Immune checkpoint inhibitors such as pembrolizumab and nivolumab, which have shown efficacy in various solid tumors. 3) Combination therapies like nivolumab plus ipilimumab, which enhance the immune response against cancer cells. 4) Emerging therapies like fecal microbiota transplantation (FMT) that may improve response to immunotherapy in solid tumors.

Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Participants with previously treated cutaneous melanoma, that is, anti-programmed cell death protein 1 (PD-1)/programmed death ligand 1 (PD-L1) alone or in combination with anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitor. Participants with BRAF-mutant melanoma must have received a v-raf murine sarcoma viral oncogene homolog B (BRAF) inhibitor as monotherapy or in combination with other targeted agents (for example, murine embryonic fibroblasts (MEK) inhibitors).

Summary

This trial tests ASP1012, a modified virus that targets and kills cancer cells, in adults with advanced or spreading tumors. The study aims to find a safe dose and check for side effects. ASP1012 helps the immune system recognize and fight cancer cells.

Who is the study for?

Adults with advanced solid tumors that have grown or spread and who've tried all standard treatments can join. It's not for those with a specific skin cancer (acral lentiginous melanoma) or ovarian cancer patients in remission without measurable disease. Participants must have confirmed diagnoses, and some will need to show certain biomarkers.

What is being tested?

ASP1012, an oncolytic virus designed to target and kill cancer cells while sparing healthy ones, is being tested alone or with pembrolizumab (an approved drug). The trial has three parts: dose finding, expanding the dose to more patients, and testing in specific cancers like stomach and colorectal.

What are the potential side effects?

Potential side effects are not listed but may include typical reactions from immune therapies such as flu-like symptoms, fatigue, allergic reactions, or issues at the infusion site since ASP1012 is given via vein.

Other Research

Oncolytic viruses like ASP1012 are designed to selectively infect and kill cancer cells while sparing healthy cells. They also make cancer cells more visible to the immune system, prompting an immune response against the tumor. This dual mechanism is particularly important for solid tumor patients as it directly targets the tumor and boosts the body's natural defenses. Other common treatments for solid tumors include chemotherapy, which kills rapidly dividing cells, and immunotherapy, which enhances the immune system's ability to fight cancer. These treatments aim to reduce tumor size, control disease progression, and improve patient outcomes.
