ImmunArray Enters Partnership with Kindstar Global

ImmunArray, a privately held molecular device company dedicated to the development of novel, blood-based in vitro diagnostic tests, and Kindstar Global Co., Ltd., a specialty clinical testing company based in Wuhan, China with locations throughout mainland China, have forged a partnership involving shared clinical studies and the launch of ImmunArray’s lupus rule-out test in China as the initial product offering.

The companies will undertake joint clinical testing of up to 500 serum samples from Chinese
patients who are healthy as well as those with symptoms consistent with systemic lupus
erythematosus (SLE) or lupus. The study will support the clinical implementation of
ImmunArray’s SLE-Key Rule-Out® test, which was introduced in U.S. markets in 2016. Previous
clinical trials have found the test delivers a differential diagnosis with >90% sensitivity and
>70% specificity.

ImmunArray will provide training to Kindstar staff in ImmunArray’s Richmond facility and onsite
in the first two labs in China. The detection platform on which the ImmunArray manufactured
iChip® test has been cleared by the CFDA which will facilitate the introduction of the first of the
tests planned for the market.

The diagnosis and treatment of lupus is not simply an American challenge but one that affects
populations around the world. The Chinese population has the second largest prevalence of
lupus in the world with over 1 million patients identified with lupus in that country today.
ImmunArray is working closely with AMPEL BioSolutions, co-founded by Drs. Peter Lipsky and
Amrie Grammer, with whom ImmunArray announced a Strategic Partnership on World Lupus
Day in May 2017. Dr. Lipsky has had the good fortune to provide training to some of the
leaders of the Chinese academic rheumatology community and maintains active collaborations
with many. He will be a co-chair of the Scientific Advisory Board with leading Chinese academic
rheumatologists, making recommendations to ImmunArray and Kindstar concerning their joint

“This partnership with Kindstar combines the resources of two innovative diagnostic
companies that are focused on finding solutions to the diagnosis of autoimmune diseases, and
we are extremely excited about the possibilities that this alliance can afford both parties,” said Donna
Edmonds, CEO of ImmunArray.

“The business relationship and expanded market opportunity this provides to Kindstar is an
important part of our strategy to be the premier specialty laboratory in China,” said Shiang
Huang, M.D., Kindstar founder and CEO. “We are focused on providing testing to a growing
number of specialists as they support patient care. This expanded product line for
rheumatologists is another demonstration of that commitment.”

As part of the agreement, Kindstar will acquire the exclusive rights to market ImmunArray’s
SLE-Key Rule-Out test in China. The launch of the product into the Chinese market is tentatively
set for November 2017 and will be formally announced at the internationally attended
American College of Rheumatology annual meeting in San Diego.
