  • Patent number: 9861623
    Abstract: The present invention provides methods for treatment of a RAS-positive disease, in particular KRAS-positive non-small cell lung cancer as well as a method for potentiating the apoptotic activity of a PDE? inhibitor by combining the PDE? inhibitor with a direct autophagy inhibitor. The PDE? inhibitor is preferably, but not exclusively, deltarasin, and the direct autophagy inhibitor is in particular 3-methyladenine. Further provided by the present invention are a kit and a pharmaceutical composition comprising the PDE? inhibitor and a direct autophagy inhibitor. The methods of the present invention in particular provide a new treatment option for RAS-positive diseases such as KRAS-positive non-small cell lung cancer allowing for an increased apoptotic activity of the PDE? inhibitor by simultaneously blocking its “tumor protective” autophagy.
