- Companies to Jointly Develop and Commercialize Probody Drug Conjugates Directed Against CD71
- AbbVie to Receive the Right to License Probody Drug Conjugates for up to Two Additional Undisclosed Targets
- CytomX to Receive $30 Million Upfront Payment
NORTH CHICAGO, Ill. and SOUTH SAN FRANCISCO, Calif., April 21, 2016 (GLOBE NEWSWIRE) -- AbbVie (NYSE:ABBV) and CytomX Therapeutics, Inc. (Nasdaq:CTMX) today announced that they have entered into a collaboration to co-develop and co-commercialize Probody™ Drug Conjugates against CD71, also known as transferrin receptor 1 (TfR1). CD71 is highly expressed in a number of solid and hematologic cancers and has attractive molecular properties for efficient delivery of cytotoxic payloads to tumor cells. Probody therapeutics are designed to take advantage of unique conditions in the tumor microenvironment to enhance the tumor-targeting features of an antibody and reduce drug activity in healthy tissues.
"We believe that the Probody platform provides a differentiated opportunity to combine with our strength in antibody drug conjugates," said Steve Davidsen, Ph.D., vice president, oncology drug discovery, AbbVie. "We are encouraged by the promising preclinical data that CytomX has generated for their Probody drug conjugate programs to-date and look forward to working closely with their team. This collaboration will enable us to expand our innovative pipeline in antibody drug conjugates and leverage our strength in that area to previously unexplored targets."
"This collaboration is another important step toward achieving CytomX's vision of transforming lives with safer, more effective therapies and allows us to further advance our broad pipeline of Probody therapeutics," stated Sean McCarthy, D.Phil., president and chief executive officer at CytomX. "AbbVie has demonstrated leadership in developing antibody drug conjugates and we look forward to collaborating with their team to realize the full potential of our CD71 Probody drug conjugate program and additional oncology targets."
Probody therapeutics are designed to remain inactive until they are activated by proteases in the tumor microenvironment. As a result, Probody therapeutics bind selectively to tumors and avoid binding to healthy tissue, to minimize toxicity and potentially create safer, more effective therapies. CytomX has generated preclinical data that demonstrates that Probody drug conjugates can safely and effectively target tumor antigens, such as CD71, that are not addressable by conventional antibody-drug conjugates.
Under the terms of the agreement, CytomX and AbbVie will co-develop a Probody drug conjugate against CD71, with CytomX leading pre-clinical and early clinical development. AbbVie will lead later development and commercialization, with global late-stage development costs shared between the two companies. CytomX will receive an upfront payment of $30 million and is eligible to receive up to $470 million in development, regulatory and commercial milestones, pending the achievement of pre-determined outcomes. AbbVie will lead global commercial activities with CytomX eligible to receive a profit share in the U.S. and tiered double-digit royalties on net product sales outside of the U.S. CytomX retains an option to co-promote in the U.S.
AbbVie also receives exclusive worldwide rights to develop and commercialize Probody drug conjugates against up to two additional, undisclosed targets. Should AbbVie ultimately pursue these targets, CytomX is eligible to receive additional milestone and royalty payments per target on any resulting products.
Conference Call / Webcast Information
CytomX will host a teleconference today at 5:00 p.m. EDT to discuss the strategic collaboration. Sean McCarthy, D.Phil., president and chief executive officer and Bob Goeltz, chief financial officer, will lead the teleconference. A live audio webcast of the presentation will be available through the Investor and News page of CytomX's website at http://ir.cytomx.com. An archived replay will be available for 90 days following the event.

About CytomX Therapeutics
CytomX is an oncology-focused biopharmaceutical company pioneering a novel class of investigational antibody therapeutics based on its Probody technology platform. The company uses the platform to create development-stage proprietary cancer immunotherapies against clinically-validated targets, as well as to develop first-in-class investigational cancer therapeutics against novel targets. CytomX believes that its Probody platform has the potential to improve the combined efficacy and safety profile of monoclonal antibody modalities, including cancer immunotherapies, antibody drug conjugates and T-cell-recruiting bispecific antibodies. Probody therapeutics are designed to take advantage of unique conditions in the tumor microenvironment to enhance the tumor-targeting features of an antibody and reduce drug activity in healthy tissues. Investigational Probody therapeutics are being developed that address clinically-validated cancer targets in immuno-oncology, such as PD-L1, against which clinical candidate CX-072 is directed, as well as novel targets, such as CD166, that are difficult to drug without causing damage to healthy tissues, or toxicities. In addition to its proprietary programs, CytomX is collaborating with strategic partners including AbbVie Inc., Bristol-Myers Squibb Company, Pfizer Inc., MD Anderson Cancer Center, and ImmunoGen, Inc.
