Beyond Anti-Angiogenesis

About Atengen

Atengen’s novel therapeutic target is expressed specifically in tumor blood vessels of most types of solid tumors but not in the blood vessels of healthy organs. Our scientists have used innovative technologies to identify several drug candidates that not only suppress tumor growth by inhibiting new blood vessel growth, but also cause extensive tumor necrosis by killing existing tumor blood vessels. In targeting the tumor blood supply rather than the tumor cells themselves, we can kill solid tumors in a tissue agnostic manner, while still maintaining a high degree of specificity. This groundbreaking approach has the potential to revolutionize the treatment of solid tumors.

A strategy to kill solid tumors in a tissue-agnostic manner

 Tumors depend on tumor blood vessels to grow and metastasize. We are developing a new generation of anti-angiogenic drugs designed to both inhibit and kill tumors by killing tumor blood vessels.

Atengen Blood Vessel Killing

Our Approach

We believe that our approach has several potential advantages compared to other solid tumor therapies that are currently available or in development.


Specific Target

Our target is highly specific; it is only found in tumor blood vessels.


Broad Target

At the same time, our target is very broad; it is present in the tumor blood vessels of most solid tumors.


Kills Tumor Blood Vessels

Our approach disrupts new tumor blood vessel growth that is mediated by multiple different angiogenic factors and results in the death of existing tumor blood vessels.


Suppress and Kill Solid Tumors

Our approach both suppresses tumor growth and kills existing tumors.


Less Susceptible to Mutagenesis

Since we are not targeting cancer cells, our approach is less susceptible to mutagenesis.
