Welcome to our website!

We proudly present a completely novel way of treating cancer, which has been published in Nature. The new concept exploits the high level of oxidative stress present within cancer that is absent in healthy cells. Oxidative stress can damage the building blocks of DNA, and the use of these damaged building blocks in DNA synthesis can cause cell death. The MTH1 protein protects cancer cells from this, and thus we aim to inhibit the MTH1 protein to specifically kill cancer cells.

When and why MTH1?

Why do cancer cells need the MTH1 protein for growing and spreading throughout the body? A new study lead by scientists from the Helleday laboratory at Karolinska Institutet together with colleagues from Stockholms University and the Heinrich-Heine University in...

“I am naturally happy and impressed by your work. Words can not describe how grateful I am; not only for my sake but for my children and family as well. It gives me hope to break the chain of cancer in the family. I hope for the drug to reach the market soon so more can be treated.” Translated from Swedish



Our vision

We believe our treatments will be turning cancer into a chronic disease and that we will be able to provide affordable treatments across the world. We reach our goal through open innovation and through a foundation, ensuring long term benefit to mankind.

Our mission

We turn cancer defects into novel treatments. Cancer cells already have a lot of DNA damage and disrupted DNA repair. By inhibiting DNA repair we increase the DNA damage to kill cancer cells, without harming healthy cells.
