What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests whether adding a new mRNA vaccine (mRNA-4157) to the standard immunotherapy drug pembrolizumab (also known as KEYTRUDA) can help people with melanoma remain cancer-free longer. It targets individuals who have undergone surgery to remove melanoma that spread to their lymph nodes and are at high risk of recurrence. Participants should be cancer-free post-surgery and show no signs of brain metastases or other active cancers. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot be on systemic steroid therapy or any other immunosuppressive therapy within 7 days before starting the trial.

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

Research has shown that the combination of mRNA-4157 and pembrolizumab has been tested for safety in people with melanoma. In these studies, participants generally tolerated the treatment well. Most side effects were mild or moderate, with only about 25% experiencing severe side effects. Importantly, the combination did not increase immune-related side effects beyond the usual levels seen with these treatments. This safety data suggests that the treatment is reasonably safe, but discussing potential risks with a healthcare provider remains important. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the combination of mRNA-4157 and pembrolizumab for melanoma because it represents a novel approach to treatment. Unlike traditional therapies, which often focus on directly attacking cancer cells, mRNA-4157 is a personalized cancer vaccine that works by stimulating the immune system to recognize and fight melanoma more effectively. This approach is combined with pembrolizumab, an immunotherapy that has already shown promise in enhancing the body's immune response against cancer. The potential for a tailored vaccine to work alongside an established immunotherapy offers hope for more precise and effective treatment options for melanoma patients.

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

Research has shown that using mRNA-4157 with pembrolizumab, which participants in this trial may receive, may help treat melanoma. Studies found that this combination reduced the risk of cancer returning or causing death by 49%. It also decreased the chance of cancer spreading or causing death by 62% compared to using pembrolizumab alone, another treatment arm in this trial. This suggests that mRNA-4157, when used with pembrolizumab, could be more effective at preventing melanoma from returning after surgery. ^{1 2 3 5 6}

Are You a Good Fit for This Trial?

This trial is for individuals who've had surgery to remove melanoma that spread to a lymph node and are at high risk of the cancer coming back. They should have no current evidence of disease, be in good physical condition (able to perform daily activities or light work), and have normal organ/marrow function. People with prior cancers, recent vaccines, blood transfusions, infections needing treatment, HIV/hepatitis B/C, autoimmune diseases or immunosuppression can't join.

Inclusion Criteria

I had surgery to remove my cancer completely within the last 13 weeks.

My skin cancer has spread to a lymph node and is likely to come back.

I am currently free of cancer after surgery, with no signs of it returning or spreading.

Exclusion Criteria

I have not taken steroids or immunosuppressants in the last week.

I have not received a live vaccine in the last 30 days.

I have not had a blood transfusion or received colony-stimulating factors in the last 2 weeks.

What Are the Treatments Tested in This Trial?

Interventions

• mRNA-4157
• Pembrolizumab

Trial Overview The study is testing if adding a personalized cancer vaccine called mRNA-4157 to pembrolizumab (a known immune therapy) after surgery can prevent melanoma from returning better than pembrolizumab alone. Participants will either receive the combination treatment or just pembrolizumab.

How Is the Trial Designed?

Group I: mRNA-4157 and Pembrolizumab Experimental Treatment 2 Interventions

Participants will receive up to 9 doses of mRNA-4157 (every 21 days). Participants may continue on pembrolizumab (every 21 days) until disease recurrence, unacceptable toxicity, or they undergo up to 18 total cycles (approximately 1 year of treatment), whichever is sooner.

Group II: Pembrolizumab Active Control 1 Intervention

Participants will receive pembrolizumab (every 21 days) until disease recurrence, unacceptable toxicity, or they undergo up to 18 total cycles (approximately 1 year of treatment), whichever is sooner.

Published Research Related to This Trial

The KEYNOTE-D36 trial is a phase II study designed to evaluate the safety and effectiveness of the personalized neoepitope vaccine EVX-01 combined with pembrolizumab in patients with unresectable or metastatic melanoma who have not previously received checkpoint inhibitor therapy.

The primary goal of the trial is to determine if EVX-01 can enhance the overall response rate in patients who initially show stable disease or a partial response to pembrolizumab, providing critical data before advancing to larger phase III trials.

The study confirms that PD-1 inhibitors like Pembrolizumab and Nivolumab improve response and survival rates in advanced melanoma patients, especially when combined with the CTLA-4 inhibitor Ipilimumab, which shows superior efficacy compared to monotherapies.

However, these immunotherapies are associated with significant immune-related adverse events, some of which can be life-threatening, highlighting the need for further studies to better understand their safety profiles and mechanisms of action.

In a phase III trial involving 1,019 patients with resected high-risk stage III melanoma, pembrolizumab significantly prolonged recurrence-free survival (RFS) compared to placebo, with a 3-year RFS rate of 63.7% versus 44.1%.

The benefits of pembrolizumab were consistent across various patient subgroups, including those with different tumor stages and BRAF mutation statuses, indicating its broad efficacy in this patient population.

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.

mRNA Vaccine Slows Melanoma Recurrence. [2023]

In a phase I/II trial involving 31 metastatic melanoma patients, a dendritic cell vaccine targeting patient-specific neoantigens showed a favorable safety profile with no serious adverse events and demonstrated a significant survival benefit compared to matched controls (1-year survival of 43% vs. 24%).

The vaccine elicited a tumor-specific immune response in 16 out of 31 patients, with a higher response rate observed after intradermal vaccination (80%) compared to intranodal (38%), suggesting that this approach could be combined with other treatments for enhanced efficacy.

In the KEYNOTE-030 expanded access program, 979 patients with advanced melanoma received pembrolizumab, showing an objective response rate of 14.5%, indicating its efficacy in this difficult-to-treat population.

The treatment was generally well-tolerated, with 19.1% of patients experiencing treatment-related adverse events, but no treatment-related deaths were reported, supporting the safety of pembrolizumab for patients with advanced melanoma.

Pembrolizumab, an anti-PD-1 antibody, has shown significant efficacy in treating advanced melanoma, demonstrating superior progression-free survival compared to chemotherapy in Phase II trials and improved overall survival in Phase III trials.

The treatment is generally well tolerated with a favorable safety profile, though common side effects include fatigue and rash, while less frequent but serious immune-related adverse events can occur.

In a post hoc analysis of the KEYNOTE-006 study involving 555 patients with advanced melanoma, both ipilimumab and BRAF ± MEK inhibitors showed antitumor activity as subsequent therapies after pembrolizumab, with overall response rates (ORR) of 17.5% for ipilimumab and 30.5% for BRAF ± MEK inhibitors.

Patients who had not previously received BRAF ± MEK inhibitors showed a significantly higher ORR of 43.2% when treated with these agents after pembrolizumab, indicating that prior treatment status may influence the effectiveness of subsequent therapies.
