The ATP-adenosine axis is believed to play a critical role in maintaining an immunosuppressed tumor microenvironment. Inhibition of one or more of the key nodes (CD39, CD73, or adenosine A2a and A2b receptors) along this axis aims to reduce the formation or activity of the highly immunosuppressive adenosine. A potential additional benefit of CD39 inhibition, aside from blocking an important source of adenosine, is the increase in intra-tumoral ATP, an important molecule for the recruitment and activation of dendritic cells. Preclinical experiments indicate that the combination of CD39 inhibition with either CD73 or adenosine receptor inhibition provides robust inhibition of this axis and increased anti-tumor immunity.
“WuXi Biologics is a global leader in the development and manufacture of therapeutic antibodies. Our relationship with WuXi Biologics started in 2017 with a clinic-ready anti-PD1 antibody, zimberelimab, which possesses molecular properties similar to those of marketed anti-PD1 therapies and has shown impressive clinical anti-tumor activity,” said Juan Jaen, Ph.D., president and head of research at Arcus Biosciences. “Furthermore, WuXi Biologics has been an excellent manufacturing partner for our anti-TIGIT antibodies, domvanalimab (AB154) and AB308. We are excited to now extend our existing relationship with WuXi Biologics by combining core competencies to discover anti-CD39 antibodies that have the potential to synergize with adenosine-targeted molecules in our existing portfolio of clinical agents. This will allow us to continue to maintain our position as one of the industry’s leading companies in the targeting of the ATP-adenosine axis for the treatment of cancer.”
“We’re thrilled to expand our strategic partnership with Arcus Biosciences to further enable this innovative company to bring new biologics solutions using WuXi Biologics’ proprietary integrated platforms. This partnership is a strong testament to our industry-leading capabilities and expertise,” said Dr. Chris Chen, CEO of WuXi Biologics. “We’re committed to offering global open-access technology platforms with premier quality standards to support our global partners as they build their innovative ideas into transformative new treatments for patients worldwide.”
Financial terms of the agreement were not disclosed, and the development of any anti-CD39 antibodies from the collaboration is not expected to materially impact Arcus’s financial position over the current cash runway.
About Arcus Biosciences
Arcus Biosciences is an oncology-focused biopharmaceutical company leveraging its deep cross-disciplinary expertise to discover highly differentiated therapies and to develop a broad portfolio of novel combinations addressing significant unmet needs. Arcus currently has four molecules in clinical development: Etrumadenant (AB928), the first and only dual A2a/A2b adenosine receptor antagonist in the clinic, is being evaluated in multiple Phase 2 and 1b studies across different indications, including prostate, colorectal, non-small cell lung, pancreatic and triple-negative breast cancers. AB680, the first small-molecule CD73 inhibitor in the clinic, is in Phase 1 development for first-line treatment of metastatic pancreatic cancer in combination with zimberelimab and gemcitabine/nab-paclitaxel. Domvanalimab (AB154), an anti-TIGIT monoclonal antibody and new potential immuno-oncology backbone therapy, is in a three-arm randomized Phase 2 study for first-line treatment of PD-L1-high metastatic non-small cell lung cancer evaluating zimberelimab monotherapy, AB154 with zimberelimab and AB154 plus AB928 with zimberelimab. Zimberelimab (AB122), Arcus’s anti-PD-1 monoclonal antibody, is also being evaluated in a Phase 1b study as monotherapy for cancers with no approved anti-PD-1 treatment options, and in various combinations across the portfolio.
