Scripps Florida collaboration awarded $3.3 million for breast cancer therapies
A pair of scientists from the Florida campus of The Scripps Research Institute have been awarded up to $3.3 million from the National Cancer Institute of the National Institutes of Health to create the next generation of breast cancer treatments for the thousands of patients whose current treatment options are limited.
Ben Shen, Scripps professor and co-chair of the department of chemistry, and Christoph Rader, Scripps associate professor in the department of immunology and microbiology, will co-lead the new fiveyear study.
The researchers aim to develop a potent type of therapy known as an antibody drug conjugate. This new class of anti-cancer drugs combines the specificity of antibodies, which attack only cells they recognize, with a highly toxic payload designed to kill specific cancer cells with far greater efficiency than most currently available treatments. So far, only three of these combination therapies have been approved by the U.S. Food and Drug Administration.
The new grant builds on the work done in both the Shen and Rader labs.
Professor Shen and his colleagues recently uncovered a new class of natural products called tiancimycins, which kill selected cancer cells more rapidly and more completely compared with the toxic molecules already used in FDA-approved ADCs.
Professor Rader, who has spent most of his scientific career at TSRI and the NIH, has been studying and developing site-specific ADCs to treat cancer.
“This grant matches my lab’s work on advancing antibody engineering and conjugation technologies with the world-class natural product-based drug discovery in Ben Shen’s lab,” Professor Rader said. “It’s precisely what I came to Scripps Florida for: to build new molecules at the interface of chemistry and biology that can advance medicine. I’m very pleased that the NIH continues to invest in our ideas.”
“At Scripps Florida we not only do great science, but we have even greater opportunities to collaborate on projects like this,” Professor Shen added. “The combination of Christoph Rader’s antibody technology and the tiancimycins, which have been proven to be exquisitely potent, should produce an antibody drug conjugate that we hope to move very quickly into the clinic.”
The Scripps Research Institute is one of the world’s largest independent, not-for-profit organizations focusing on research in the biomedical sciences. TSRI is internationally recognized for its contributions to science and health, including its role in laying the foundation for new treatments for cancer, rheumatoid arthritis, hemophilia, and other diseases. An institution that evolved from the Scripps Metabolic Clinic founded by philanthropist Ellen Browning Scripps in 1924, the institute now employs more than 2,500 people on its campuses in La Jolla, Calif., and Jupiter, Fla., where its renowned scientists — including two Nobel laureates and 20 members of the National Academies of Science, Engineering or Medicine — work toward their next discoveries. ¦
