PI3K inhibitors are a common area of research in finding a successful treatment of cancer. The PI3K pathway is important for cell growth, apoptosis, cell metabolism, cell survival, and a multitude of other functions. There are multiple isoforms of PI3K that can be broken down into three categories: class I, II, and III. Each isoform has at least one subunit that helps with the functionality of the isoform. Mutations found in the PI3K isoforms are commonly seen in many different types of cancer and the use of inhibitors is being tested to stop the cell survival of cancer cells. Individual PI3K inhibitors have shown some inhibition of the pathway; however, there is room for improvement. To better treat cancer, PI3K inhibitors are being combined with other pathway inhibitors. These combination therapies have shown better results with cancer treatments. Both the monotherapy and dual therapy treatments are still currently being studied and data collected to better understand cancer and other treatment options.
