-Proceeds will advance the company’s lead program into clinical trials-

NEW HAVEN, Conn., March 10, 2021 (GLOBE NEWSWIRE) -- Cybrexa Therapeutics, an oncology-focused biotechnology company developing a new class of therapeutics through its alphalex™ Peptide Drug Conjugate (PDC) tumor targeting platform, today announced the completion of its $25 million Series B financing. The financing included HighCape Capital and new investor Elm Street Ventures. Proceeds from the financing will be used to support the planned advancement of Cybrexa’s lead candidate CBX-12 (alphalex™-exatecan) into the clinic. The first patient dosing in the Phase 1 study is expected in the first half of 2021.

"We are pleased that our efforts continue to be recognized and supported by our investors. This funding is a testament to our company's progress, execution and the strength of our alphalex™ platform technology," said Per Hellsund, President & CEO of Cybrexa. "This round of financing will be deployed to support the planned Phase 1 study for CBX-12."

CBX-12 is a novel treatment for solid tumors that includes a highly potent topoisomerase I inhibitor payload that is in the same class as the payloads used by antibody-drug conjugates (ADCs) ENHERTU^® and TRODELVY™. In contrast to these ADCs, CBX-12 is able to target cancer cells independent of antigen overexpression, which should greatly expand the addressable patient populations. The positive results from the GLP toxicology study of CBX-12 will serve as a guide for the dosing regimen in the planned Phase I trial.

"We believe Cybrexa’s technology and science form the basis for a robust development platform, capable of producing multiple targeted therapeutic options, for a variety of oncology indications," said Kevin Rakin, Partner of HighCape Capital. "We see the progress of CBX-12 into human trials as a significant milestone for the platform, as well as providing even more opportunities from a business perspective."

About CBX-12

CBX-12 is a novel treatment for solid tumors that includes a highly potent topoisomerase I inhibitor payload that is in the same class as the payloads used by antibody-drug conjugates (ADCs) ENHERTU^® and TRODELVY™. In contrast to these ADCs, CBX-12 is able to target cancer cells independent of antigen overexpression, which should greatly expand the addressable patient populations. Positive results from the GLP toxicology study of CBX-12 will serve as a guide for dosing regimen for the planned Phase I trial of CBX-12, as Cybrexa filed the IND on February 19, 2021. CBX-12 is currently being investigated in collaboration with NCI in pre-clinical safety and efficacy studies in the solid tumor landscape. This partnership will also explore its therapeutic potential to conduct trials in a wide number of indications and in combination with other therapies such as immune-oncology and PARP inhibitors.
