What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a combination of treatments to determine if they can stop melanoma, a type of skin cancer, from growing. It uses a mix of therapies, including a special cell-based treatment called Alpha-type-1 Polarized Dendritic Cells, which boosts the immune system, and medications like interferon alpha-2, rintatolimod, and celecoxib, which work together to fight the cancer. The trial targets individuals with melanoma that hasn’t responded to previous treatments. Participants must have a specific immune system marker called HLA-A2+ and have tried treatments that include PD-1 or PD-L1 agents. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to important advancements in melanoma treatment.

Will I have to stop taking my current medications?

The trial requires that you stop taking systemic immunosuppressive agents, including steroids, at least 3 weeks before starting the study, unless they are for endocrine dysfunction and are 10 mg or less of prednisone (or equivalent). Other medications are not specifically mentioned, so it's best to discuss your current medications with the study team.

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

Research shows that the treatments in this trial are generally safe. Studies have found that alpha-type-1 polarized dendritic cells can safely enhance the immune system in other types of cancer, with patients experiencing positive immune responses without serious side effects.

Celecoxib, a common pain reliever, has been safely used in many conditions, including some cancers. It has shown compatibility with other melanoma treatments without major problems.

Recombinant interferon alfa-2b has long been used to treat various diseases, including melanoma. Some reports mention serious side effects, such as mood changes or immune system issues, but these are known and monitored during clinical trials.

Rintatolimod has been studied in different cancers, showing promise in improving survival rates and generally being well-tolerated, although it is still under study for full approval in some cases.

Overall, these treatments have been used in other studies with good safety records, but monitoring for any side effects remains important. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about this combination therapy for melanoma because it targets the cancer in a multi-faceted way. Unlike standard treatments, like surgery, chemotherapy, and immunotherapy drugs such as ipilimumab or PD-1/PD-L1 inhibitors, this approach uses a mix of recombinant interferon alfa-2b, rintatolimod, and alpha-type-1 polarized dendritic cells. The unique aspect is the use of dendritic cells, which are designed to boost the immune system's ability to recognize and attack melanoma cells more effectively. This could potentially enhance the body's immune response to the cancer, offering a promising new strategy for patients who haven't responded to existing treatments.

What evidence suggests that this trial's treatments could be effective for melanoma?

In this trial, participants will receive a combination of treatments, including alpha-type-1 polarized dendritic cells (aDC1), recombinant interferon alpha-2b, celecoxib, and rintatolimod. Research has shown that aDC1 can significantly enhance the body's defense against melanoma, a type of skin cancer. One study found that aDC1 can produce 40 times more long-lasting cancer-fighting cells than standard treatments. Interferon alpha-2 has been proven to help melanoma patients live longer, with some studies showing a 24% increase in survival over five years. Celecoxib, a common pain reliever, has also been found to reduce the growth of melanoma cells and improve the effectiveness of other treatments. Rintatolimod boosts the immune system and has shown promise when used with other therapies, making it a strong candidate for fighting tumors. Together, these treatments aim to stop melanoma from growing or spreading. ^{1 2 3 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• Alpha-type-1 Polarized Dendritic Cells
• Celecoxib
• Recombinant Interferon Alfa-2b

Patients receive recombinant interferon alpha-2 IV over 30 minutes, rintatolimod IV over 2.5 hours, and celecoxib PO BID on days 1-3. Beginning cycle 2, patients also receive alpha-type-1 polarized dendritic cells ID on day 1. Treatment repeats every 3 weeks up to 4 cycles in the absence of disease progression or unacceptable toxicity. At 12 weeks, patients with progressive disease may switch to ipilimumab with or without a PD-1/PD-L1 inhibitor and patients with a complete response CR, PR, or stable disease SD may switch to a PD-1/PD-L1 inhibitor or best alternative care.

Interferon (IFN) alpha-2b is currently the only available adjuvant therapy for high-risk melanoma and has been shown to improve overall and recurrence-free survival based on meta-analyses of clinical trials.

Despite concerns about its toxicity and the need for more research to identify which patients will benefit most, IFN should be recommended for patients at high risk of melanoma recurrence, with specific guidelines based on disease stage provided by an Italian Expert Panel.

High-dose interferon alpha2b (IFN-alpha2b) effectively reverses T cell signaling defects and promotes dendritic cell polarization in melanoma patients, leading to improved immune responses.

Clinical trials have shown that high-dose IFN-alpha2b significantly reduces relapse rates and improves overall survival compared to observation or other treatments, highlighting its efficacy as an adjuvant therapy for high-risk melanoma.

High-dose adjuvant interferon alpha-2b (IFN alpha 2b) improves quality-adjusted survival (QAS) for melanoma patients, with 77% of patients in one trial experiencing a benefit, although this was not statistically significant for all.

The effectiveness of IFN alpha 2b on QAS is influenced more by patients' perceptions of its toxicity rather than the fear of melanoma recurrence, indicating that cancer patients may have a higher tolerance for treatment side effects compared to the general population.

A new method for generating human dendritic cells (DCs) has been developed, producing fully mature type-1 polarized DCs (alphaDC1) that are highly effective in inducing type-1 immunity, particularly in cancer treatment.

These alphaDC1 cells show significantly higher production of interleukin-12p70 and can generate up to 40-fold more long-lived cytotoxic T lymphocytes (CTLs) against melanoma antigens compared to the current standard DCs, suggesting a promising advancement for cancer vaccines.

In a study involving 11 metastatic melanoma patients, lower doses of IFN-alpha-2b (5 megaunits/m²) were found to be as effective as higher doses (10 megaunits/m²) in activating immune cells, specifically in phosphorylating STAT1.

The research indicates that increasing the dose to 10 megaunits/m² did not enhance the induction of interferon-stimulated genes (ISGs) and led to higher levels of inhibitors of IFN-alpha signaling, suggesting that lower doses may be sufficient for therapeutic effects.
