It has been a longstanding challenge to effectively treat solid tumors. No effective treatment is available for a large number of patients with solid tumors. Key challenges include tumor resistance to drugs, inaccessibility of cells within a tumor to certain drugs, and the lack of tumor specificity of many drugs. These challenges that many existing treatment strategies cannot overcome demand new strategies.
An "Achilles heel" of tumors is the tumor blood vessel, which tumors depend on for survival and metastasis. There are major advantages of targeting tumor blood vessels in drug development and these advantages can help to overcome the traditional challenges of treating solid tumors. First, tumor blood vessels are not tumor cells and should be less susceptible to mutation and the acquisition of drug resistance. Second, they are easily accessible by drugs. Third, tumor blood vessels differ drastically from blood vessels of healthy organs in formation, structure and gene expression. Atengen aims to develop a novel strategy to treat solid tumors by precision killing of tumor blood vessels to kill tumors.
Atengen’s novel therapeutic target is a receptor that is specifically expressed in tumor blood vessels of most types of solid tumors but not in the blood vessels of healthy organs. We have developed innovative technologies to identify both small molecule and antibody drug candidates that can effectively kill tumors by killing existing tumor blood vessels through this receptor. In targeting the tumor blood supply rather than the tumor cells themselves, this new strategy can kill solid tumors in a tissue agnostic manner, while maintaining a high degree of specificity. This groundbreaking approach has the potential to overcome the limitations of existing strategies and to revolutionize the treatment of solid tumors.

A new strategy to treat solid tumors

Atengen is developing drugs that specifically target the tumor blood vessels of most solid tumors. The long-term goal is to develop a new generation of therapeutics to treat solid tumors.
