Cybrexa regains rights to CBX-12

Cybrexa Therapeutics announced the Company will regain all rights to CBX-12, a clinical-stage, first-in-class peptide drug conjugate that utilizes Cybrexa’s proprietary alphalex technology to enhance delivery of exatecan to tumor cells, as its collaboration partner, Exelixis, Inc., has provided a notice of termination for the right to acquire CBX-12. “We appreciate the excellent collaboration we had with Exelixis and the advances we made working together on the CBX-12 clinical program. This collaboration has positioned Cybrexa to move CBX-12 into phase II trials later this year,” said Per Hellsund, President & CEO, Cybrexa.
