US drug company obtains worldwide rights for an antibody fragment that may have an advantage in treating cancer patients
Champions Biotechnology, Inc. (OTC Bulletin Board: CSBR), a U.S. Oncology drug development company with a predictive preclinical platform aimed at accelerating the development and enhancing the value of oncology drugs, has established an exclusive licensing agreement with Ramot at Tel Aviv University Ltd., Tel Aviv University's wholly owned technology transfer company.
The licensing agreement encompasses the development and commercialization of TAR-1, a single-chain antibody fragment in preclinical development that may have an advantage in treating cancer patients because of its high specificity and affinity to binding mutant p53 protein.
Under the terms of the agreement, Champions has obtained the worldwide rights to TAR-1 and is responsible for the further development of the compound. Champions will utilize its Biomerk Tumorgraft(TM) platform technology to evaluate the activity of TAR-1 and determine the best path forward for the compound in regards to indication, patient population and potential drug combinations. Ramot will receive an upfront payment and will be eligible to receive milestone payments and royalties if Champions chooses to continue the license terms, which will be determined based on results from testing TAR-1 in the predictive Tumorgraft platform.
Inhibits tumor growth
Prof. Beka Solomon from Tel Aviv University identified that TAR-1 binds to and restores the wild-type active conformation of mutant p53 protein with a high degree of specificity, leading to in vivo inhibition of tumor growth. Given the frequency of mutant p53 in cancer, TAR-1 has the potential to target a wide range of human cancers.
"Licensing TAR-1 demonstrates the progression of our strategy to build our own Tumorgraft-driven pipeline of oncology drugs, which we expect to yield improved clinical development success rates," said Guy Malchi, Champions Biotechnology's Head of Corporate Development and International Operations.
