STAT’s post from the summit says Stephen Hoge of Moderna discussed the company’s partnership with Merck on an mRNA cancer vaccine. The program’s lead candidate, intismeran autogene, is an investigational treatment tailored to an individual patient. It is not a preventive vaccine for healthy people.
A vaccine built from one tumor
Intismeran, also known as V940 or mRNA-4157, starts with a sample of a patient’s tumor. Researchers identify mutations unique to that cancer and build a synthetic mRNA sequence encoding as many as 34 neoantigens. The aim is to teach the immune system to recognize those markers and generate T-cell responses against cancer cells.
Merck and Moderna are developing the therapy together and testing it with Keytruda, Merck’s approved anti-PD-1 immunotherapy. The combination is being studied after surgery, when treatment is intended to lower the risk that cancer returns.
