Cancer Targeted Technology Receives an SBIR Grant and Announces Expansion of Its Pipeline

“This new chemotherapeutic drug, CTT1700, like all of CTT’s drugs, are based on the same versatile modular PSMA-targeting platform. This platform allows for rapid development of various PSMA-targeted agents by conveniently swapping out the payload,” commented Dr. Cliff Berkman, Professor of Chemistry at Washington State University (WSU) and consultant to CTT as its Chief Scientific Officer. Dr. Berkman and WSU were instrumental in developing the new drug-release technology for CTT1700 that was licensed to CTT in 2017.

CTT’s pipeline now includes three important drugs targeting cancers that express PSMA. CTT1057 is a diagnostic PET imaging agent capable of rapidly and sensitively detecting metastatic disease in prostate cancer patients. CTT1057 demonstrated excellent results in Phase 1 clinical trials completed in 2017 and the drug was licensed to AAA/Novartis in January, 2018. The second agent, CTT1403, is a radiotherapeutic drug that delivers a therapeutic dose of 177-lutetium to tumor cells expressing PSMA. CTT1403, unlike other PSMA-targeted drugs, includes an albumin binding component that imparts a long circulation time allowing for more of the drug to get to the tumor cells. CTT1403 is expected to start Phase I clinical trials in prostate cancer patients in early 2019. CTT1700, currently in preclinical development, is the third agent in CTT’s pipeline and would be the first drug to use binding to the PSMA biomarker to target chemotherapy to prostate cancer.
