PAI Life Science’s Biochemistry Expertise Links with Hemex Health’s Gazelle™ Miniaturized Rapid Diagnostic Platform to Develop Pandemic Test

Two Pacific Northwest Companies Partner to Develop Affordable COVID-19 Six Minute Diagnostic Test for Use in Low Resourced Countries

Portland, Oregon, UNITED STATES

SEATTLE and PORTLAND, Ore., April 15, 2020 (GLOBE NEWSWIRE) -- Researchers in Seattle and Portland have agreed to collaborate on an urgently needed rapid COVID-19 diagnostic test that can diagnose patients accurately, quickly, and inexpensively, anywhere in the world. The platform behind the rapid COVID-19 test is designed to work in low resourced locations from Mumbai to Mogadishu, and remote villages in between. Researchers expect to have the device ready for a clinical study within a few months.

Once developed and necessary approvals are obtained, the affordable technology will be used for early detection of cases of COVID-19 to help health workers stop the spread of the disease on short notice.

The COVID-19 diagnostic uses Portland-based Hemex Health’s Gazelle Diagnostic platform that combines known and trusted testing with cloud-based reporting, in a reader smaller than a shoebox, battery powered, and chargeable with a cell phone charger. Gazelle combines miniaturized electrophoresis with automation and a video interface for rapid, easy, and consistent reading.  Significantly, Gazelle eliminates the need for cold-chain necessary with many diagnostic technologies but difficult to maintain in tropical climates.

Because new viruses may arise anywhere at any time, researchers have long sought a diagnostic platform that can be deployed worldwide, used with little training, that would communicate data in real time.  Gazelle allows for low-cost testing suitable for use in local health clinics, small labs, doctor’s offices, field hospitals, and emergency situations. 

“When it comes to viruses, our world knows no boundaries,” said Patti White, CEO, Hemex Health.  “Health care workers and global health experts urgently want an affordable, easy to operate diagnostic platform that connects even the most remote village with public health so that new outbreaks can be identified quickly. 

“The Gazelle platform combines artificial intelligence, cloud-based data reporting, and miniaturized proven diagnostic technologies that will revolutionize diagnostics the way smart phones changed communications,” said White.

“We need COVID-19 diagnostics like Gazelle that can be used broadly in under resourced countries, to eliminate transmission there and to remove the constant threat of re-introduction elsewhere,” said David Bell, PhD, former World Health Organization scientist who developed and tested diagnostics implementation and training guidance used internationally by Ministries of Health around the world. “The Gazelle platform provides integration of rapid, low cost testing with connectivity and digital integration fundamental to future surveillance programs around the world.”

While Hemex Health engineered the intelligent reader and cartridge, Seattle-based PAI Life Sciences is developing the biochemical assay required to accurately detect a protein on the surface of COVID-19.  PAI has identified an antigen-based mechanism that recognizes the shed protein of the COVID virus.

“We are using a highly specific technology to recognize shed proteins from the virus that causes COVID-19.” said Darrick Carter, PhD, President and CEO, PAI Life Sciences and Affiliate Professor, Global Health, University of Washington. “This unique approach should be more sensitive than antibody-based tests so it can identify even trace viral presence.”

PAI Life Sciences developed the first point of care diagnostic screening tool for leprosy and is collaborating on an innovative vaccine for COVID-19 to begin human clinical trials soon.
