1
Moderna Therapeutics
Funding: $3.9B
Moderna is a pioneer in developing a new class of drugs based on messenger RNA (mRNA). This new drug platform is based on the discovery that in-vitro engeneered and injected mRNA can direct the body's cellular machinery to produce virtually any protein of interest, from native proteins to antibodies and other entirely new protein constructs with therapeutic activity both inside and outside cells. In other words, mRNA can guide the body to produce its own drugs. Moderna used mRNA to create the first COVID-19 vaccine and is now applying this technology to create vaccines for infectious diseases (influenza, RSV, HSV, etc.), immuno-oncology (melanoma, lung cancer, liver cancer, etc.), rare diseases and autoimmune diseases.
