We recently received authorization from the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) for our Phase 1/2 clinical study evaluating mRNA-4194, an investigational mRNA-based vaccine for people with Lynch syndrome, an inherited condition that increases the risk of cancer.

David Berman, our Chief Development Officer, sat down for an episode of IR Insights to provide an overview of this innovative program and Moderna’s research in the cancer prevention vaccine space: https://t.co/zMnU3nVxim

Today we announced detailed results from a planned five-year follow-up analysis of the Phase 2b randomized KEYNOTE-942/mRNA-4157-P201 study evaluating intismeran autogene (mRNA-4157 or V940), an investigational mRNA-based individualized neoantigen therapy, in combination with KEYTRUDA® (pembrolizumab), @Merck's anti-PD-1 therapy, in patients with high-risk melanoma (stage III/IV) following complete resection.

These data will be presented today at the 2026 American Society of Clinical Oncology (@ASCO) Annual Meeting (May 29-June 2) and published simultaneously in ASCO’s Journal of Clinical Oncology.

Early detection matters when it comes to melanoma. The American Academy of Dermatology recommends regularly checking your skin — including areas that are easy to miss, like your scalp, back, palms, soles, and between your toes.

If you notice a mole or spot that looks different, changes, itches or bleeds, make an appointment with a board-certified dermatologist. Regular skin checks, sun protection, and avoiding tanning beds can all help support skin health. #MelanomaAwarenessMonth

Melanoma outcomes can improve significantly when the disease is identified in its earliest stages, with a 95% 5-year survival rate when caught early. Knowing your skin and paying attention to changes like new or evolving moles, spots, or bumps is important.

Regular skin self-checks, annual dermatology visits, sun protection, and avoiding tanning beds can all help reduce risk and support earlier identification of melanoma, when it may be easier to treat.
