GLA’S PIONEERING RESEARCH FUNDING STRATEGY RESULTS IN PROMISING OUTCOMES THAT HELP PATIENTS SUFFERING FROM LONG-TERM LYME DISEASE
STAMFORD, CONN (April 12, 2019)—Global Lyme Alliance’s commitment to identify and fund innovative and promising Lyme disease research is unrivaled. A vital component to GLA’s leadership role in Lyme disease research is its success with early-stage funding. Discovering and supporting researchers who are new to Lyme but bring years of relevant disease work or are at the beginning of their careers, helps distinguish GLA’s approach to finding the evidence-based answers that will ultimately help patients.
In 2009, on a limited research budget, GLA had decided to proactively recruit scientists and fund research in new areas to further the understanding of Borrelia burgdorferi (the Lyme bacteria) that could lead to an improved diagnostic test and ultimately, a cure, for Lyme disease. GLA’s objectives were to:
- determine if the antibiotic evading technique of bacteria, like Escherichia coli, is being used by the Lyme bacteria and therefore explain the typical patient experience of symptom improvement followed by symptom relapse
- determine if such persistent or dormant cells were protected within biofilms
- identify existing drugs from a vast FDA library and find novel new treatments to eliminate persister (non-growing) and growing Lyme bacteria which could be a cure
- identify the surface proteins of the persister form of the bacteria to improve the current diagnostic tests. The first step in achieving these objectives was to fund a study conducted by Ying Zhang, M.D. at Johns Hopkins University in early 2010, to see if the Lyme bacteria could form persister or dormant cells in the test tube; and if they did, to proceed with the other aforementioned aims
Based on early findings of the Zhang/Johns Hopkins study that showed that the Lyme bacteria could ‘morph’ into persisters, GLA then recruited Kim Lewis, Ph.D., Director of the Antimicrobial Discovery Center at Northeastern University, who is an expert in the area of bacterial persistence and antibiotic tolerance. GLA worked with Dr. Lewis on developing a multi-year study design and agreed to fund it. This study would ultimately confirm the ability of Lyme organisms to become persisters and went on to then find existing and new drugs to kill these persister (non-growing) forms. Both Northeastern and Johns Hopkins were running parallel, independent experiments and drug discovery protocols backed by GLA.
By 2018, Dr. Ying Zhang and his team at Johns Hopkins made significant strides:
- Confirmed the existence in vitro of the dormant, persister Lyme bacteria
- Showed how the Lyme bacteria goes dormant and changes its protein composition and shape when exposed to antibiotics and then grows again when antibiotic treatment is stopped
- Identified its protein components and a new diagnostic tool to recognize persistence in patients
- Used high-throughput drug discovery and drug efficacy testing programs
- Identified a powerful combination of Daptomycin + Cefuroxime + Doxycycline to eliminate growing and non-growing forms of the bacteria and identified essential oils from spice and culinary herbs (g., oregano, cinnamon bark, and clove bud) which also serve to eliminate persister bacteria as well as biofilm-like forms
By 2018: Dr. Kim Lewis and his team at Northeastern University, independently, also made considerable findings:
- Confirmed the existence in vitro of the dormant, persister Lyme bacteria
- Showed how the Lyme bacteria goes dormant when exposed to antibiotics and then springs back to a form capable of growing again
- Using a separate drug screening tool, identified Daptomycin, Mitomycin C (an anticancer agent) and Ceftriaxone as a possible drug combination to eliminate dormant and growing cells
- Discovered through Dr. Lewis’ pipeline discovery program that Disulfiram, used for treating alcoholism, was extremely effective in culture and in mice in to killing burgdorferi in all forms
- Discovered an antibiotic through his proprietary approach to screen soil bacteria, known as Hygromycin A that could kill the Lyme bacteria in vitro and in mice
- Proved that in vitro, Vancomycin was more powerful in clearing all forms of the Lyme bacteria than Doxycycline
The complete path from initial seed funding to results that will impact patients follows.
GLA Initial Seed Funding (2013)
- GLA is the first to identify Dr. Lewis as a scientific expert looking at bacterial persister cells, antibiotic tolerance, and novel therapies who could apply his knowledge to the study of Lyme disease
- GLA helps design and funds Dr. Lewis’ multi-year study, “Persister Cells and Antibiotic Tolerance in Bb” to investigate whether burgdorferi forms antibiotic-tolerant persister forms
GLA Annual Lyme Disease Research Symposium (2014)
- In 2014, through regular progress reports to GLA Scientific Advisory Board and presenting at GLA’s annual Lyme Disease Research Symposium, Dr. Lewis shares his initial findings from GLA-funded study. At the Symposium are other top scientists, including Dr. Brian Fallon, Dr. Armin Alaedini, and Dr. John Aucott
- Lewis finds that B. burgdorferi can go dormant to evade antibiotics and then restart replication once antibiotics are removed. He had then performed an initial screen of FDA drugs for novel compounds that could target persister forms of the Lyme bacteria
- Lewis was honored at Global Lyme Alliance Greenwich Gala, along with Ying Zhang, M.D., Ph.D., of Johns Hopkins University for their work in discovering Borrelia persisters
Published Findings (2015): The Lyme bacteria morphs to evade antibiotics
- Lewis publishes landmark paper on persisters in Antimicrobial Agents and Chemotherapy, “Borrelia burgdorferi, the Causative Agent of Lyme Disease, Forms Drug-Tolerant Persister Cells”, based on GLA funding from 2013. He showed that antibiotics killed most lab-grown B. burgdorferi, with a small surviving population that tolerated drug treatment. His team found that Mitomycin C efficiently killed persisters
- Lewis noted that persisters play dead and then reawaken once treatment is completed in the context of recurrent urinary tract infections. “They start multiplying again, he explains, “and you get this relapsing, chronic infection.” It is possible a similar situation and explanation exists for chronic Lyme disease; however, more research is needed to test this hypothesis
GLA Fosters Collaboration & Continues Funding (2016, 2017, 2018)
- In 2016, GLA funds Dr. Lewis’ well-regarded study “Discovery of new antibiotics and combinations”
- Initial findings include results using Disulfiram (an FDA-approved drug for the treatment of chronic alcoholism and Hygromycin A (an antibiotic derived from soil bacteria)
- In 2017 and 2018, a top Lyme-treating physician starts implementing Dr. Lewis’ findings using Disulfiram to treat post-treatment Lyme disease patients. To date, on a limited number of patients, Disulfiram is proving very promising
- GLA-funded researcher and Lyme-treating physician Dr. Brian Fallon of Columbia University designs a clinical study to determine therapeutic efficacy of Disulfiram in 2019
- Thanks to four years of financial backing by GLA, Dr. Lewis is able to deliver ground-breaking discoveries in Lyme disease, in particular, persisters and novel treatments, enabling him to attract attention from additional private foundation donors. This enables Dr. Lewis greater opportunity to investigate new therapies for chronic Lyme patients
Published Findings (2018): Vancomycin is the strongest antibiotic in treating Lyme disease
- In 2018, Dr. Lewis publishes important paper on novel therapies in Antimicrobial Agents and Chemotherapy, “Identifying Vancomycin as an Effective Antibiotic for KillingBorrelia burgdorferi“, based on GLA funding.
- Lewis’ team found that Vancomycin was effective against in vitro cultures of growing B. burgdorferi. However, this class of drugs is not expected to work on stationary persister cells, in which growth is very slow, and cell wall synthesis is expected to be minimal. Unexpectedly, when tested on stationary B. burgdorferi, they found that cell wall synthesis still occurred, and could be blocked by Vancomycin.
- To extend their studies to an in vivo model, the group treated burgdorferi-infected, immunodeficient mice for five days. They found that Vancomycin and Ceftriaxone each completely blocked bacterial growth, compared with partial eradication by Doxycycline. These studies suggest that more effective antimicrobial drugs, used early in infection, may prevent or reduce the occurrence of persisting infection.
Clinical Trials & Helping Patients (2019)
- In 2019, GLA helps facilitate clinical trials leveraging Dr. Lewis’ findings with respected Lyme-treating physicians. Clinical trials performed under the guidance of GLA’s rigorous peer-reviewed process will ensure valid results, to most effectively impact patients.
Lyme disease is extremely complex, and the challenge to understand it and ascertain how to most successfully treat patients impacted by it is a herculean task. Through an aggressive and innovative research strategy, backed by a world-renowned Scientific Advisory Board and top-notch in-house science team, GLA is finding the answers.

Credit should be given where credit is due. GLA is kicking butt in the world of Lyme/MSIDS research.
Currently, Disulfiram is being used on numerous Lyme/MSIDS patients in Mexico and many more in the U.S. with pretty astounding results. The herxes can be surreal so it takes an experienced practitioner, but, it has action against malaria, HIV, cancer and Lyme (borrelia):
- Scroll to 39:00. Dr. Lewis states they were looking for compounds specific to Bb, so it wouldn’t be toxic. Disulfiram is selective for Bb and blew Vancomycin, Ceftriaxone, and Doxycycline out of the water and is very safe. It completely sterilizes Bb and kills persisters in vivo.
- Disulfiram has a long half-life of 60-120 hours, crosses the blood brain barrier, is slowly absorbed in the digestive tract and is also eliminated slowly making effects last up to two weeks after initial intake.
Do not self-treat. Talk to your practitioner about these findings and work with him/her. While Disulfiram (Antabuse) is cheap, it can cause vast die-off and an inflammatory response that could put you in the ER.
