What is the purpose of this trial?

This trial explores whether adding a Tetanus Diphtheria (Td) or Polio Boost Immunization (IPOL) vaccine can be safely combined with standard immune checkpoint inhibitor therapy for advanced melanoma. Researchers aim to determine if these vaccines are safe and feasible alongside treatment for melanoma that has spread. Participants will receive their assigned vaccine during the fourth cycle of their ongoing cancer therapy. Those with confirmed advanced melanoma, who have not yet received systemic treatment and are scheduled to start certain immune therapies, may be suitable for this study. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants a chance to be among the first to receive this innovative approach.

Do I need to stop my current medications for the trial?

The trial protocol does not specify if you need to stop your current medications. However, if you are on immunosuppressive therapy or steroids above a certain dose, you may not be eligible to participate.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that both the Polio Boost Immunization and the Tetanus Diphtheria Vaccine are very safe. Polio vaccines, like the one used in this study, rank among the safest available, with no serious side effects reported. They have successfully prevented polio for many years and are well-tolerated.

Similarly, the Tetanus Diphtheria Vaccine is considered safe. It is commonly used and usually only causes mild side effects, such as a sore arm at the injection site. It has proven effective in preventing infections and is a regular part of vaccination programs.

Both vaccines have a long history and strong scientific support for their safety. This study is a Phase 1 trial, specifically designed to assess the vaccines' safety in people, with significant attention given to how well participants handle the vaccines. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for advanced melanoma because they use vaccines typically associated with infectious diseases to potentially boost the immune response against cancer. The IPOL vaccine, a polio booster, and the Td vaccine, for tetanus and diphtheria, are being administered directly in proximity to tumors. This novel approach leverages the body's immune system in a unique way, potentially enhancing the effectiveness of existing immunotherapy. Unlike standard melanoma treatments, which often involve targeted therapies or checkpoint inhibitors, these vaccines could offer a new mechanism to stimulate the immune system to fight cancer cells more robustly.

What evidence suggests that these vaccines could be effective for advanced melanoma?

In this trial, participants will receive either the Polio Boost Immunization (IPOL) or the Tetanus Diphtheria (Td) vaccine. Research has shown that the IPOL vaccine can enhance the body's defenses in areas like the intestines, which is crucial for fighting infections. Specifically, studies demonstrated that IPOL increased intestinal immunity in children who had received the oral polio vaccine. Meanwhile, the Td vaccine is known to be safe and effective in preventing tetanus and diphtheria, and it has strongly activated the body's immune response. Both vaccines aim to strengthen the immune system, potentially helping the body fight cancer more effectively when used with treatments called immune checkpoint inhibitors. ^{2 6 7 8 9}

What Are the Treatments Tested in This Trial?

Interventions

• Polio Boost Immunization
• Tetanus Diptheria Vaccine

Trial Overview The study tests the safety and feasibility of giving a Tetanus Diptheria Vaccine (Td) or Polio Boost Immunization (IPOL) alongside standard immune checkpoint inhibitor therapies in patients with metastatic melanoma. It aims to see if these vaccines can boost the body's immune response when given during cycle 4 of IO therapy.

How Is the Trial Designed?

Group I: Td Vaccine Experimental Treatment 1 Intervention

The first 15 subjects enrolled will receive the Td (tetanus diphtheria) vaccine at cycle 4 of IO therapy. The Td vaccine is administered as 0.5 mL intramuscular injection in the extremity (thigh or upper arm) in closest proximity to the largest tumor.

Group II: IPOL Vaccine Experimental Treatment 1 Intervention

Subjects 16 through 25 will receive the IPOL (polio booster) vaccine at cycle 4 of IO therapy. The IPOL vaccine is administered as 0.5 mL intramuscular or subcutaneous injection in the extremity (thigh or upper arm) in closest proximity to the largest tumor

The Oncept melanoma vaccine, which targets the tyrosinase protein, is approved for treating stage II to III canine oral melanoma and is considered safe for use in dogs.

Despite its safety, the evidence regarding its effectiveness in improving survival rates is inconsistent, leading to controversy within the veterinary oncology community.

In a study involving 45 immunocompetent patients with solid tumors, significant morbidity was observed from the immunization with BCG, PPD, and tumor cells, including painful ulcerations and potential tumor growth enhancement in some patients.

Despite the adverse effects, the treatment led to notable changes in cellular immunity, such as enhanced skin reactions to microbial antigens and evidence of immunologic memory, but did not result in significant regression of untreated tumor lesions.

Vaccination with peptide mimotopes of the melanoma cell-adhesion molecule (Mel-CAM) led to strong antibody responses in mice, especially when these mimotopes were coupled with tetanus toxoid, indicating their potential as effective components of tumor vaccines.

The study demonstrated that both coupled and uncoupled mimotopes could stimulate T cell responses, with coupled mimotopes promoting a balanced Th1 and Th2 cytokine response, while uncoupled mimotopes favored a Th1 response, suggesting they can effectively induce both humoral and cellular immunity against tumors.
