It is a highly selective inhibitor of pan-Akt, namely, of all three Akt isoforms Akt1, Akt2, and Akt3.[1]

It is intended to be used with other cancer therapies that advanced tumours may become resistant to.[3]

Clinical trials

2011: A phase 1 clinical trial of MK-2206 alone has reported it was well tolerated.[4]
2014: A phase 1 clinical trial of MK-2206 with a variety of other agents in 72 patients with advanced cancer reported acceptable side-effects.[3]
2016: MK-2206 is one of the treatments in the I-SPY2 Adaptive clinical trial for breast cancer that had been selected for later stage trials.[5]
As of August 2017 31 phase II clinical trials are registered, many completed.[6] e.g. in colorectal cancer, breast cancer, and many others.

MK-2206 and COVID-19

Data shown in a study preprint suggest that SARS-CoV-2 infection decreases cellular autophagy and that MK-2206, which induces autophagy, reduced virus replication by up to 88% in vitro. The study's authors propose that MK-2206 should be tested in clinical trials as a potential treatment for COVID-19.[7]
