CAMBRIDGE, MA and SOUTH SAN FRANCISCO, CA / ACCESSWIRE / January 5, 2023 / Moderna, Inc. (NASDAQ:MRNA), a biotechnology company pioneering messenger RNA (mRNA) therapeutics and vaccines, and CytomX Therapeutics, Inc. (NASDAQ:CTMX), a leader in the field of conditionally activated oncology therapeutics, today announced a collaboration and licensing agreement to create investigational mRNA-based conditionally activated therapies utilizing Moderna's mRNA technologies and CytomX's Probody^® therapeutic platform.

The research collaboration will leverage core scientific advances at Moderna and CytomX. Moderna's mRNA platform builds on continuous advances in basic and applied mRNA science, delivery technology and manufacturing, and has allowed the development of therapeutics and vaccines for infectious diseases, immuno-oncology, rare diseases, cardiovascular diseases, and autoimmune diseases. CytomX's Probody technology enables proteins to be activated locally in diseased tissue, while remaining masked in systemic circulation. These advances open up the strategy of encoding potent, masked biologics with mRNA, for the potential treatment of a wide range of diseases.

"We are excited to enter this collaboration with CytomX to combine our technologies and to potentially bring mRNA-based conditionally activated therapies to patients," said Rose Loughlin, Ph.D., Moderna's Senior Vice President for Research and Early Development. "Moderna and CytomX have a shared vision of investing at the intersection of biology and technology to transform the lives of patients, and this collaboration will expand applications of our growing therapeutics pipeline."

"At CytomX, we have always embraced bold science in building the potential of Probody therapeutics and we are thrilled to be joining forces with Moderna in oncology as well as expanding our technology to areas outside oncology where we believe there is great potential," said Sean McCarthy, D.Phil, CEO and Chairman of CytomX. "Moderna's global impact has shown the enormous power of mRNA and we look forward to working closely with our newest collaborator to bring novel, mRNA-based conditionally activated therapeutics to patients with unmet medical needs."

About the Alliance

Under the terms of the agreement, CytomX will receive an upfront payment of $35 million, including $5 million of pre-paid research funding. CytomX will continue to receive research funding and is eligible to receive up to approximately $1.2 billion in future development, regulatory, and commercial milestone payments. CytomX is also eligible to receive tiered royalties on global net sales of any products that are commercialized under the agreement. Moderna and CytomX will collaborate on discovery and pre-clinical development and Moderna will lead clinical development and commercialization of therapeutics resulting from the agreement. The agreement additionally provides Moderna with an option to participate in a future equity financing by CytomX subject to certain terms, conditions and regulatory requirements.

About Moderna

In over 10 years since its inception, Moderna has transformed from a research-stage company advancing programs in the field of messenger RNA (mRNA), to an enterprise with a diverse clinical portfolio of vaccines and therapeutics across seven modalities, a broad intellectual property portfolio in areas including mRNA and lipid nanoparticle formulation, and an integrated manufacturing plant that allows for both clinical and commercial production at scale. Moderna maintains alliances with a broad range of domestic and overseas government and commercial collaborators. Most recently, Moderna's capabilities have come together to allow the authorized use and approval of one of the earliest and most effective vaccines against the COVID-19 pandemic. Moderna has been named a top biopharmaceutical employer by Science for the past eight years. To learn more, visit www.modernatx.com.

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 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. CytomX has also established strategic collaborations with multiple leaders in oncology, including AbbVie, Amgen, Astellas, Bristol Myers Squibb, Regeneron and Moderna.
