About mRNA-4157
Moderna is creating an individualized, mRNA-based personalized cancer vaccine to deliver one medicine for one patient at a time.
Through next-generation sequencing, Moderna identifies mutations found on a patient’s cancer cells, called neoepitopes. Neoepitopes can help the immune system distinguish cancer cells from normal cells. Using algorithms developed by its in-house bioinformatics team, Moderna predicts 20 neoepitopes present on the patient’s cancer that should elicit the strongest immune response, based on unique characteristics of the patient’s immune system and particular mutations. Moderna then creates a vaccine that encodes for each of these mutations and loads them onto a single mRNA molecule.
Once injected into the patient, the vaccine should direct the patient’s cells to express the selected neoepitopes. In turn, this may help the patient’s immune system better recognize cancer cells as foreign and destroy them. Leveraging its rapid cycle time, small-batch manufacturing technique and digital infrastructure, Moderna plans to manufacture and supply each individually manufactured personalized cancer vaccine to patients within weeks.
