SOUTH SAN FRANCISCO, CA and TARRYTOWN, NY, USA I November 17, 2022 I CytomX Therapeutics, Inc. (NASDAQ: CTMX) and Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced a collaboration and licensing agreement to create conditionally-activated investigational bispecific cancer therapies utilizing CytomX’s Probody® therapeutic platform and Regeneron’s Veloci-Bi® bispecific antibody development platform.
The collaboration is strategically focused on applying CytomX’s biologic masking strategies to develop investigational Regeneron bispecifics that remain inactive until activated by proteases in the tumor microenvironment. This technology has the potential to widen the therapeutic window and help minimize off-target effects for these next-generation T-cell engaging therapies, potentially addressing tumor types that have historically been unresponsive to immunotherapy.
“At Regeneron, we’re focused on developing a paradigm-changing portfolio of oncology medicines for patients, by combining a deep understanding of cancer biology with cutting-edge technologies,” said John Lin, M.D., Ph.D., Senior Vice President, Immuno-oncology and Head of Bispecifics, at Regeneron. “This collaboration will enable Regeneron and CytomX to combine our collective oncology expertise with two premier platforms – Probody and Veloci-Bi – to develop novel immunotherapies and research their potential to transform patient lives.”
“CytomX has pioneered the field of conditionally-activated therapeutics through high quality and differentiated science, leading to broad experience in biologic masking strategies and a deep understanding of the protease tumor microenvironment,” said Sean McCarthy, D. Phil, CEO and Chairman of CytomX. “We are thrilled that our scientific expertise has attracted Regeneron as our newest collaborator, and we look forward to working closely together to further optimize T-cell engager strategies and push the boundaries of cancer immunotherapy to new levels.”
Under the agreement, Regeneron and CytomX will collaborate on the discovery activities to identify and validate conditionally active bispecific antibodies. Regeneron will be responsible for funding preclinical and clinical development and commercialization activities. CytomX will receive an upfront payment of $30 million and will be eligible to receive future target nomination payments and preclinical, clinical, and commercial milestones of up to $2 billion. CytomX is also eligible to receive tiered global net sales royalties.
About CytomX Therapeutics, Inc.
CytomX is a clinical-stage, oncology-focused biopharmaceutical company dedicated to destroying cancer differently. By pioneering a novel class of conditionally activated biologics, powered by its Probody® technology platform, CytomX’s goal is to transcend the limits of current cancer treatments. CytomX’s robust and differentiated pipeline comprises seven therapeutic candidates across multiple treatment modalities including antibody-drug conjugates (“ADCs”), T-cell engaging bispecific antibodies (“TCBs”), and immune modulators such as cytokines and checkpoint inhibitors (“CPIs”). CX-2029 is an investigational conditionally activated antibody-drug conjugate (ADC) directed toward CD71, which has demonstrated encouraging antitumor activity in patients with squamous non-small cell lung cancer and is being developed in collaboration with AbbVie. CytomX’s clinical pipeline also includes cancer immunotherapeutic candidates against validated targets such as the CTLA-4-targeting Probody therapeutics, BMS-986249 and BMS-986288, partnered with Bristol Myers Squibb, as well as CX-904, a conditionally activated T-cell-engaging bispecific antibody targeting the epidermal growth factor receptor (EGFR) on tumor cells and the CD3 receptor on T cells, which is partnered with Amgen. In addition, CytomX has a diverse preclinical portfolio of wholly-owned assets including CX-801, an interferon alpha-2b Probody cytokine that has broad potential applicability in traditionally immuno-oncology sensitive as well as insensitive (cold) tumors and CX-2051, a conditionally activated ADC directed toward EpCAM, with potential applicability across multiple EpCAM-expressing epithelial cancers. Praluzatamab ravtansine is an investigational conditionally activated ADC directed toward CD166 that demonstrated single agent clinical activity in a Phase 2 study for patients with advanced HR+/HER2-non-amplified breast cancer. Following the Phase 2 results, CytomX decided not to further progress praluzatamab ravtansine alone and is seeking a partner to further develop the molecule. CytomX has also established strategic collaborations with multiple leaders in oncology, including AbbVie, Amgen, Astellas, Bristol Myers Squibb and Regeneron.
