Idasanutlin (RG-7388) is a second-generation, orally bioavailable, selective p53-MDM2 antagonist. MDM2 is an important negative regulator of the p 53 tumor suppressor and is expressed at high levels in a large proportion of acute myeloid leukemia (AML). Blocking the MDM2-p53 interaction stabilizes p53 and activates p-53 mediated cell death and inhibition cell growth. Idasanutlin is under clinical trial in phase III for treatment AML and in combinations with others drugs in phase I/II for treatment of multiple myeloma.

Icosabutate (also known as PRC-4016 or NST-4016), a cholesterol ester transfer protein inhibitor was developed by NorthSea Therapeutics for the treatment of combined dyslipidemias and hypertriglyceridemia. Icosabutate successfully completed phase II clinical trial for hypertriglyceridemic subjects, where was studied the drug efficacy and safety. In April 2018 NorthSea Therapeutics announced that its lead product, icosabutate would be further developed as an effective and safe therapeutic approach to treating both non-alcoholic steatohepatitis and its associated comorbidities.

SAR-405838 is an inhibitor of the interaction between the oncoprotein murine double minute 2 (MDM2) and p53. SAR-405838 was investigated in phase I clinical trials in patients with locally advanced/metastatic solid tumor with wild-type TP53 or with TP53 mutation prevalence below 40%. SAR-405838 had an acceptable safety profile with limited activity in patients with advanced solid tumors.
