What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores whether a new personalized vaccine, intismeran autogene (also known as V940), combined with the cancer drug pembrolizumab, can better prevent melanoma (a type of skin cancer) from returning compared to pembrolizumab alone. People who have had their melanoma surgically removed and have not yet received other treatments may be suitable candidates. Participants will receive either the combination of the new vaccine and pembrolizumab or a placebo with pembrolizumab to determine which is more effective at preventing cancer recurrence. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking cancer prevention.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, if you are HIV-infected, you must have well-controlled HIV on anti-retroviral therapy (ART).

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

Research has shown that the combination of intismeran autogene (formerly mRNA-4157 or V940) and pembrolizumab is generally safe. Previous studies tested this treatment in individuals with solid tumors, focusing on tolerability without serious side effects.

The combination of V940 and pembrolizumab has shown promising results in other studies. Evidence suggests that this combination can reduce the risk of cancer recurrence by almost half compared to pembrolizumab alone, indicating both effectiveness and good tolerability.

Since pembrolizumab is already approved for other conditions, extensive safety information is available. This ensures that testing the combination with V940 is conducted responsibly. However, it is important to remember that any treatment can have side effects, which may vary among individuals. ^{1 2 3 4 5}

Why are researchers excited about this study treatment for melanoma?

Researchers are excited about the V940 vaccine combined with pembrolizumab for treating melanoma because it introduces a novel approach to cancer therapy. Most treatments for melanoma, like traditional immunotherapies, aim to boost the body's immune response to attack cancer cells. However, the V940 vaccine is unique as it customizes the immune response by using a personalized mRNA approach, potentially enhancing the body's ability to recognize and destroy melanoma cells. This combination with pembrolizumab, a well-established immunotherapy, might improve efficacy by offering a dual mechanism of action that could lead to better outcomes for patients.

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

In this trial, participants will receive either the V940 vaccine (also called mRNA-4157) with pembrolizumab or a placebo with pembrolizumab. Research has shown that the V940 vaccine combined with pembrolizumab can significantly aid in treating melanoma, a type of skin cancer. Specifically, studies found that this combination reduced the chance of cancer returning by 49% compared to using pembrolizumab alone. It also lowered the risk of cancer spreading or causing death by 62%. These findings suggest that the V940 vaccine with pembrolizumab is a promising option for preventing melanoma recurrence. ^{1 2 3 4 6}

Participants receive up to 9 doses of intismeran autogene via an intramuscular (IM) injection (every 3 weeks) plus up to 9 doses of pembrolizumab via an intravenous (IV) infusion (once every 6 weeks) until disease recurrence or unacceptable toxicity, or for a total treatment duration of up to approximately 56 weeks, whichever is sooner.

Group II: Placebo + Pembrolizumab Active Control 2 Interventions

Participants receive up to 9 doses of dose matched placebo to intismeran autogene via an IM injection (every 3 weeks) plus up to 9 doses of pembrolizumab via an IV infusion (once every 6 weeks) until disease recurrence or unacceptable toxicity, or for a total treatment duration of up to approximately 56 weeks, whichever is sooner.

In a study of 88 advanced melanoma patients treated with pembrolizumab, 81.8% experienced any-grade toxicities, with skin and gastrointestinal issues being the most common side effects.

Despite the high incidence of side effects, pembrolizumab was found to be well tolerated in real-world settings, and severe toxicities were manageable with systemic steroids.

The phase IIb KEYNOTE-942 trial suggests that the investigational mRNA-4157/V940 vaccine combined with pembrolizumab may significantly reduce the risk of disease recurrence in high-risk melanoma patients after surgery.

Patients receiving this combination therapy showed better outcomes compared to those treated with only the PD-1 inhibitor, indicating a promising new approach for adjuvant therapy in melanoma.
