SUPPLEMENTARY INFORMATION: The HHS
Lyme Innovation initiative is a patientcentered, data-driven approach to the threat of Lyme disease and tick-borne diseases. Lyme disease affects more than 300,000 people in the U.S. each year and accounts for more than 70% of all vector-borne diseases in our country.
Lyme and other tick-borne diseases cost the U.S. economy billions of dollars annually.
The HHS Lyme Innovation initiative uses strategic public-private partnerships to accelerate advancements in Lyme disease and other tick-borne diseases. The Lyme Innovation initiative aims to build commitment to patientcentered innovations, identify ways to collect and share data while raising awareness, accelerate the discovery of next-generation diagnostic tools and technologies, and lower barriers across all phases of development, testing, and implementation.

of the Tick-Borne Disease Working Group to HHS inform the Lyme Innovation initiative. The Lyme Innovation initiative represents one way that HHS is executing the strategies described in A National Public Health Framework for the Prevention and Control of Vector-Borne Diseases in Humans.
HHS has entered into a public-private partnership with the Steven and Alexandra Cohen Foundation to form the LymeX Innovation Accelerator LymeX. LymeX will accelerate the Lyme Innovation initiatives progress and strategically advance tick-bornedisease solutions in direct collaboration with Lyme disease patients, patient advocates, and diverse stakeholders. A
primary goal of the LymeX partnership and the Framework is the development of new diagnostic technologies for Lyme disease.
The Centers for Disease Control and Prevention CDC website https
www.cdc.gov/lyme/index.html summarizes information about the stages of Lyme disease, current diagnostic testing recommendations, and treatment options. CDC currently recommends the use of FDA cleared serologic tests in a two-step testing process that detects the presence of antibodies to Borrelia burgdorferi, the bacterium responsible for Lyme disease.
Serologic tests for diagnosis of Lyme disease have technical limitations.
Antibodies may not be produced by the immune system early enough or in high enough quantities to meet the detection limit of these tests https
www.hhs.gov/sites/default/files/tbdwgreport-to-congress-2018.pdf. As an antibody response in infected persons requires time to develop, serologic tests for Lyme disease may produce false negative results during early infection.
In areas where Lyme disease is highly endemic, the infection may be diagnosed without laboratory testing if patients develop a diagnostic skin lesion at the site of the tick bite, which is known as erythema migrans EM or a bullseye rash. However, 20% of patients may not develop this specific rash, and sometimes the rash is not seen or recognized. The rash also might not display the stereotypical presentation.
Therefore, these newly infected patients may not be diagnosed in the absence of a sensitive diagnostic test and may not receive prompt or proper treatment for a disease with the potential to cause disabling illness.
Serology tests are also not capable of determining if there is an active infection. As antibodies normally persist for months or even years after the infection is gone, serologic testing

cannot be used to determine a cure.
Additionally, cross-reactions between serologic tests for Lyme disease and those for other infectious diseases can also yield false positive results.
These limitations of serological testing compound the scientific challenges in identifying specific etiologies for Post-Treatment Lyme Disease Syndrome PTLDS, which is characterized by persistence of symptoms for more than 6 months following treatment with oral antibiotics. Improvements in Lyme disease diagnostics would enable better clinical management of PTLDS patients as well.
HHS has identified an area of known need in developing more advanced diagnostic tests that diagnose infection at all stages of Lyme disease. Therefore, the LymeX partnership is embarking on a series of initiatives, including prize challenges to develop new diagnostic tests for Lyme disease. This RFI is intended to gather information on the current state of the science and development landscape for new diagnostic tests from the entrepreneurs, scientists, and physicians who will develop and use them.
We encourage responders to answer the following questions:
What challenges/barriers exist for the development and validation of innovative diagnostic tests for Lyme disease?
What types of diagnostic technologies are being developed or could be developed or adapted to detect Lyme disease, including technologies and breakthroughs adapted from COVID19 diagnostics with potential applications for Lyme disease e.g., highly sensitive nucleic acid amplification testing NAAT?
What emerging technologies e.g., epigenetic mapping, inflammatory markers, gene arrays, NAAT, or others might be developed or adapted to characterize different stages of Lyme disease, including Post-Treatment Lyme Disease Syndrome PTLDS, etc.?
What analyte e.g., DNA, RNA, protein, metabolite does existing or developing Lyme disease diagnostic tests detect?
What is the optimal sample type e.g., whole blood, plasma for the detection of a test analyte in patients with Lyme disease? The optimal sample type can be generally defined as the one where the analyte can be best detected.
What challenges exist in the implementation and use of Lyme disease diagnostic testing in clinical practice?
What role can or should publicprivate partnerships play in accelerating
