Ipatasertib

Ipatasertib (RG7440) is an experimental cancer drug in development by Roche. It is a small molecule inhibitor of AKT, which is a key component of the PI3K/AKT pathway. Ipatasertib was discovered by Genentech in collaboration with Array Biopharma and is currently in phase III trials for treatment of breast cancer.^[1]
