The round was co-led by 3Ã-5 Partners, based in Portland, Ore., and St. Louis-based Lightchain Capital, LLC, the family office of Scottrade founder Rodger Riney.

Adarza plans to use the funds to support full commercialization of ZIVA, its automated biological testing platform for academic and clinical research. Scheduled for commercial launch in June, the ZIVA platform will allow researchers to quickly identify inflammation, cardiovascular, and oncology protein biomarkers for disease profiling and drug development.

"Other testing platforms fall short," said 3Ã-5 Partners Managing Director Joe Biller. "Because of its speed, automation, and simplicity, we see immense opportunity with Adarza's technology, particularly when it comes to drug development and personalized medicine."

Adarza's technology includes a bench-top instrument and a portfolio of multiplexed assays that can assess hundreds of protein biomarkers simultaneously from a single biological sample, like tissue or blood, according to Bryan Witherbee, Adarza's president and CEO. Using proprietary methods to create arrays of biologically active molecules on silicon chips, an endless number of targets can be detected in a single test, including antibodies, nucleic acids, peptides, and whole viruses/bacteria.

St. Louis-based biotech company Wugen is already using the ZIVA platform as it develops gene-editing technologies to develop cell therapies for cancer treatment.

"Adarza's ZIVA immunoassays are enabling us to follow more biomarkers, helping us speed up our ability to develop allogeneic CAR-T therapies," said John McKearn, Ph.D., CEO of Wugen.

With today's Series D funding, Adarza has raised a total of $54 million.

Earlier round investors in Adarza include BioGenerator, RiverVest Venture Partners, Cultivation Capital, and Lewis & Clark Ventures.

With the Series D close, Adarza is adding two new board members: Drew Dennison, managing director for St. Louis-based Lightchain, and Joe Biller, 3Ã-5 Partners managing director.

Adarza is also in the process of expanding its team to support commercialization efforts in 2020.
