ModernA’s mRNA cancer vaccine combined with Merck's immunotherapy reduced melanoma recurrence or death risk by 42%, according to a Phase 3 clinical trial involving over 1,100 patients. The study also showed a 38% reduction in the spread of cancer and revealed that 82.2% of patients receiving both treatments remained cancer-free after two years compared to 70% for those treated with Keytruda alone. ModernA plans to…

Moderna and Merck released results from a major study showing that an mRNA-based cancer vaccine called intismeran significantly reduces by 42% the risk of melanoma returning two years after surgery. The personalized vaccine, which targets unique gene mutations in each patient's tumor, was administered alongside standard post-surgery treatment to over 1,100 people with high-risk melanoma. At the end of the trial, 82%…

Moderna and Merck announced on October 22 that their customized cancer vaccine for late-stage melanoma reduces recurrence or death risk by 42% over two years compared to standard treatment. The study involved more than 1,130 patients who had tumors surgically removed and were then given either the intismeran vaccine (along with Keytruda) or a placebo plus Keytruda. Intismeran uses mRNA technology to help immune…

Professor Georgina Long led a world-first cancer vaccine trial that significantly reduced the risk of melanoma recurrence or death by 42% compared to patients treated with only pembrolizumab (Keytruda). The study, involving 1,137 participants across 157 global sites, tested an individualised mRNA vaccine called intismeran, developed by Moderna and MSD. This breakthrough could revolutionize cancer treatment…

A large trial has shown that a personalized mRNA cancer vaccine for melanoma reduces the risk of recurrence or death by 42% when used with immunotherapy. The study involved over 1,100 high-risk melanoma patients who had surgery to remove their tumors. This vaccine works by targeting specific markers on each patient’s tumor and activating an immune response against these unique cancer mutations. The combination…
