Lynx Bio makes headway on new diagnostic for blood cancer drugs

The group, which also included UW-Madison professors Shigeki Miyamoto and David Beebe, and postdoctoral fellow Edmond Young, would receive large numbers of patient samples from hospitals containing cancer cells so that the researchers could analyze them, Pak says.

One major challenge they faced was that some of the samples, which were derived from patient biopsies, did not have large enough counts of cancer cells to be useful to the researchers.

“This was very unfortunate because these patients were volunteering to give us biopsy samples, but we were only able to analyze about half of them,” Pak says. “And on the scientific side, we were potentially biasing our data.”

Given that frustration, they decided they would try to miniaturize the culture system they were working with, so that it would be possible to analyze all of the samples rather than having to throw some of them away, she says.

It took more than three years to finalize a design for a device able to functionally analyze low numbers of blood cancer cells. Soon after, in 2013, Pak formed Lynx Biosciences, a Madison, WI-based startup she continues to lead. The ultimate goal is to be able to test cancer drugs—either alone or in combination with others—on a patient’s own cells, so that people caring for the patient can create an individualized treatment regimen. Lynx is currently in the middle of a second clinical study of the device, and working to secure seed-stage financing (more on those efforts below) to further advance the technology toward FDA approval.
