posted , gotta be yr ago that they opened a sleeping giant with mRNA tech ,that its next target to be at cancer , well...to add from my previous post
clever MRK !!!!!!
pharma giant Merck has paid Moderna $250 million to co-develop and commercialize a promising personalized cancer vaccine based on its mRNA technology.
The background: In
2016, pharma giant Merck gave Moderna
$200 million to research and develop personalized cancer vaccines based on mRNA. At the time, it was a big bet — mRNA technology had yet to be translated into any approved vaccine.
Part of the original agreement specified that if Moderna could complete proof-of-concept studies of mRNA-based personalized cancer vaccines in humans, Merck had the option to pay an undisclosed amount to co-develop and commercialize the shots with Moderna.
What’s new? Merck is now exercising its option on mRNA-4157, a personalized cancer vaccine in a phase 2 clinical trial for skin cancer. It’s being studied in combination with Merck’s cancer treatment Keytruda, a humanized monoclonal antibody.
“This long-term collaboration combining Merck’s expertise in immuno-oncology with Moderna’s pioneering mRNA technology has yielded a novel tailored vaccine approach,” said Eliav Barr, head of global clinical development and CMO of Merck Research Laboratories.
A personalized cancer vaccine: Moderna’s cancer vaccine works differently than most vaccines because
it’s designed to treat an existing disease rather than prevent it entirely. It’s also personalized for each patient, while other shots are typically mass produced and distributed to the population.
To create each vaccine, Moderna takes a sample of a patient’s tumor. It then uses genetic sequencing technology to identify proteins in the tissue called “neoantigens.” These proteins are found only on the surface of cancer cells, and they are unique to each person’s tumor.
Moderna then uses its mRNA technology to create a vaccine that instructs cells to make up to 34 of the cancer’s specific neoantigens, which are shown off to immune cells as potential targets. The idea is that this will trigger an immune response against the neoantigens, helping the immune system identify and attack cancerous cells.
Looking ahead: For Moderna’s ongoing phase 2 trial of mRNA-4157, 157 patients with high-risk
melanoma had their tumors removed via surgery.
Some of the patients were then given nine doses of a personalized cancer vaccine and a dose of Keytruda every three weeks for approximately one year or until their melanoma came back. The rest were given just a dose of Keytruda every three weeks for one year.
The trial’s primary endpoint is recurrence-free survival, and given Merck’s new investment in the vaccine, it seems reasonable to expect positive results.

big pharma going to throw the kitchen sink at this. We get a clearer pic of its efficacy or lack thereof ,id say by late 2024....looking good early , its real early
