Key points

• Regarding 112, 000 new melanoma cases will be diagnosed this year in the US.
• The firms stated this is the first positive phase 3 result for a personalized cancer vaccine and demonstrates "meaningful improvement" over treatment with Keytruda alone.
• The new drug is an mRNA vaccine, like the vaccines applied for COVID-19.
• Intismeran autogene, created by Moderna, could eventually save lives by helping keep cancer under control in more patients.
• This means each vaccine has information that's unique to a patient's specific cancer.

Notably, a vaccine has been shown to support keep melanoma, the deadliest form of skin cancer, from coming back in patients at higher risk of recurrence, the drug makers stated.

Regarding 112, 000 new melanoma cases will be diagnosed this year in the US. More than 8, 500 are projected to die from this cancer in 2026.

Notably, the new drug was tested with Keytruda (aka pembrolizumab, an immunotherapy created by Merck) in phase 3 trials, the final major stage of testing before a drug can be submitted to the FDA for approval.

Notably, the firms stated this is the first positive phase 3 result for a personalized cancer vaccine and demonstrates "meaningful improvement" over treatment with Keytruda alone. It has been employed for more than a decade in cancer care.

Notably, the results mark a step forward in the effort to treat not just melanoma but other forms of cancer with vaccines designed to support keep patients disease-free.

With intismeran and Keytruda together, researchers discovered that patients with later-stage melanoma (stage 2B up to stage 4) went longer without their cancer returning and without it spreading to distant parts of the body.

Notably, the new drug is an mRNA vaccine, like the vaccines applied for COVID-19. These work by giving the body instructions on how to identify and fight a disease. Unlike the COVID vaccine, intismeran is personalized.

This means each vaccine has information that's unique to a patient's specific cancer. It works by teaching the immune system what to look for so it can better find and destroy the cancer on its own.

This has benefits over treatments such as chemotherapy. It can launch a broad attack on both healthy and cancerous cells. Cancer vaccines like intismeran are designed to be more targeted, giving immune system specific information regarding the cancer so it can continue to recognize and attack it.

This is especially significant for later-stage melanoma patients. This person have a much higher risk of recurrence. While someone with stage 3C cancer had an 85% chance, for example, someone with stage 2C cancer had a 45% chance of recurrence. A revolutionary treatment, a step closer to a cure.

There are a number of other cancer vaccines using intismeran being studied in phase 2 and 3 trials, with the goal of treating cancers like lung cancer, bladder cancer and kidney cancer.

In practice, the vaccines don't work on their own. It is why they're being tested with an immunotherapy like Keytruda.

That's since even when the body is given specific information concerning the tumor so it knows what to hunt, tumors can sometimes evade detection by tricking the immune system.

Keytruda works with the cancer vaccine by helping prevent cancer cells from hiding from the immune system, allowing T-cells to come in and kill them.

Cancer vaccines are an enormously promising field since of their precise targeted, approach and potential to provide long-term protection against recurrence.

Experts believe that going forward, cancer vaccines could support "to eradicate advanced cancer, cure patients in the adjuvant setting, and prevent the development of malignancy in high-risk patients."

In short, new vaccine prevents deadliest skin cancer from coming back: drugmakers is the central thread here, and readers can expect follow-up reporting as the picture becomes clearer.
