Principal Investigator, Dr. Felicia Chow, Talks about the New Lyme Clinical Trials Center at UCSF

By Bay Area Lyme Foundation

BAL Leading the Way Series

“I was seeing more and more patients here at UCSF who hadn’t traveled to Massachusetts, New Jersey, or other places endemic for Lyme, but rather had just been in the California Bay Area or on West Coast trips to places that we don’t consider—at least by the classic maps—as being endemic Lyme areas.”

– Felicia Chow, MD, Associate Professor of Neurology and Medicine at University of California, San Francisco

There’s been much excitement in the Lyme community regarding the founding and development of the Lyme Clinical Trials Network since it was first announced. With a $1m seminal grant from Bay Area Lyme Foundation, UCSF joined the Clinical Trials Network to further study and develop better treatments for patients with Lyme and other tick-borne diseases. The Network aims to address the need for high quality, innovative clinical trials to develop evidence-based treatments for patients with persistent Lyme symptoms following initial antibiotic treatment—a population that has grown to more than two million Americans and continues to increase. We sat down with Principal Investigator, Dr. Felicia Chow, to learn more about plans for this California Clinical Trials Network node, and her role as Director of the UCSF Neuro-Infectious Diseases Clinic.

Dr. Chow is a neurologist specializing in infectious diseases. This means she’s particularly interested in how pathogens like bacteria, viruses, and parasites, invade the nervous system and cause neurological damage and/or symptoms. Her expertise is in managing conditions such as brain abscesses, neurocysticercosis (a parasitic infection of the brain), neurosyphilis, and neurological complications associated with HIV. Additionally, she is well-versed in infectious causes of meningitis, encephalitis, and myelitis.

In this article transcribed from our Distinguished Speaker Series webinar, Sunjya Schweig, MD, founder and CEO of the California Center for Functional Medicine and member of Bay Area Lyme’s Scientific Advisory Board, discusses how recovering from tick-borne illnesses can be aided through carefully devised combinations of conventional and functional medicine, tailored to the individual person. Nancy Chimsky, retired interior designer and Lyme patient, who has been challenged with tick-borne infections since 1997, shares her personal Lyme story in the first part of this webinar.

Dr. Schweig discussed the top four lifestyle areas critical to aiding recovery and explains how and why optimizing each area is key to treating and managing Lyme and tick-borne disease. The lifestyle areas are:

Diet and nutrition
Stress reduction and neuroplasticity
Sleep
Detoxification

Dr. Schweig also discussed the important role that botanical and herbal medicines have in recovery. He discusses the individualized nature of treatment and testing for Lyme disease, including the use of various lab tests and the consideration of co-infections. Finally, Dr. Schweig emphasizes the importance of finding the right healthcare practitioner who can address the complexity of Lyme disease and provide appropriate treatment. The session concludes with a Q&A session about what people are doing to manage their health, and Dr. Schweig provided practical suggestions and concrete takeaways based on these questions from attendees.

BAL Spotlights Series

In her book, The Art of Living With Chronic Illness, Pain, and Disability: A Practical and Spiritual Approach Inspired by the 12-Step Recovery Model, author, and former social worker Shellie Krick, explores how she used the 12-step Al-Anon program as a template to cope with her Lyme disease. Shellie has experienced over 30 years of chronic health problems stemming from Lyme and Bartonella infections, misdiagnosis, and dangerous, unproven treatments—some of which caused serious harm. Her book stems from her personal journey, offering a step-by-step guide to developing a different way of handling daily life with a chronic illness or chronic pain.

“I definitely wasn’t the type of person who liked sitting around doing nothing—Lyme has been really hard on me in that way. But through my book, if I can help just one person cope with their situation better, then I will feel I have accomplished a lot.”

Combination Antibiotic Therapies May Be Capable of Eradicating Lyme Disease, According to Investigational Study Funded by Bay Area Lyme Foundation

Study identifies persistent Lyme bacteria in tissue samples and points to need for clinical studies of combination antibiotics in persistent Lyme

PORTOLA VALLEY, Calif., November 21, 2023—Bay Area Lyme Foundation, a leading public foundation sponsor of Lyme disease research in the US, today announced results of a laboratory study published in the peer-reviewed journal Frontiers in Microbiology that identifies seven combination therapies that are superior to courses of single antibiotics for treating persistent Lyme disease in an investigational model. These combination therapies were able to eradicate the bacteria from tissue samples, and the study was conducted by Bay Area Lyme Foundation Scientific Advisory Board member Monica Embers Ph.D., along with other researchers from Tulane University.

“Our results support the experience of Lyme disease patients whose symptoms have not resolved after a standard course of antibiotics, and these new data suggest that combination therapy should be investigated in clinical studies for treating persistent human Lyme disease,” said Embers, an associate professor of microbiology and immunology and director of Vector-borne Disease Research at Tulane National Primate Research Center.

While none of the single courses of antibiotics eliminated persistent infection in this investigational study, some combinations of already FDA-approved antimicrobial treatments were able to eradicate the bacteria. Specifically, four different dual combinations of antibiotics (doxycycline and ceftriaxone; dapsone and rifampicin; dapsone and clofazimine; doxycycline and cefotaxime) and three triple combinations of antibiotics and antimicrobials (doxycycline, ceftriaxone and carbomycin; doxycycline, cefotaxime and loratadine; dapsone, rifampicin and clofazimine) eradicated persistent infections of Borrelia burgdorferi, the bacteria that causes Lyme disease.

Research Funded by Bay Area Lyme Foundation Identifies New Investigational Therapy Regimen Capable of Irreversibly Damaging Lyme Bacteria in Laboratory Tests

Inspired by research that targets cancer tumors, these new findings in Lyme could also lead to novel R&D strategies for other diseases

PORTOLA VALLEY, Calif. November 1, 2023—Bay Area Lyme Foundation, a leading sponsor of Lyme disease research in the US, today announced the development of a potential new drug, HS-291, that targets and destroys Borrelia burgdorferi, the bacterium that causes Lyme disease. Published in the peer-reviewed journal Cell Chemical Biology, this laboratory study represents a novel paradigm shift for anti-microbial treatment research as it is the first to target and inhibit Borrelia burgdorferi HtpG (high temperature protein G), a specific type of enzyme within the bacteria that causes Lyme disease— a condition affecting nearly 500,000 new patients annually. The research was conducted at Duke University School of Medicine, with collaboration from University of North Carolina, Tulane University, and Stanford University, and HS-291 is currently in preclinical stage testing at UC Davis.

“As Lyme disease is currently treated with broad spectrum antibiotics and there are no targeted treatments, we are particularly excited about this discovery, and hopeful that our novel Lyme disease therapeutic HS-291 will specifically destroy the Lyme bacterium without off-target effects or antibiotic resistance,” said Timothy Haystead, PhD, professor of Pharmacology and Cancer Biology, Duke University School of Medicine, Bay Area Lyme Foundation grantee, and co-lead author. “This research has been an incredible opportunity to leverage knowledge from oncology to Lyme disease in order to design an investigational therapeutic that could one day benefit hundreds of thousands of patients with Lyme.”

This new discovery has implications beyond Lyme disease as it demonstrates that using the drug HS-291 to deliver cellular toxins to HtpG, a type of non-essential enzyme that assists the folding or unfolding of large and complex proteins, greatly expands what can be considered druggable within any pathogen and opens a whole new area of infectious disease research.

Bay Area Lyme Foundation ELA Winner Uses Metabolic Modeling to Predict 77 Unique Drug Targets in Lyme Disease Bacterium

Bay Area Lyme Foundation ELA Winner Uses Metabolic Modeling to Predict 77 Unique Drug Targets in Lyme Disease Bacterium

Results will help inform future research and development of new Lyme disease therapeutics

PORTOLA VALLEY, Calif., October 19, 2023—Bay Area Lyme Foundation, a leading sponsor of Lyme disease research in the US, today announced the findings of a study identifying new essential gene and enzyme drug targets in Lyme disease bacterium, which resulted, in-part, from a grant provided to Peter Gwynne, one of Bay Area Lyme Foundation’s 2022 Emerging Leader Award (ELA) winners. Published in the peer-reviewed journal mSystems, the study uses the most comprehensive metabolic modeling to date to predict 77 unique drug targets in Borrelia burgdorferi, the bacterium that causes Lyme disease—a condition affecting nearly 500,000 new patients annually.

“Lyme disease is often treated using long courses of antibiotics, which can cause side effects for patients and risks the evolution of antimicrobial resistance. Our research supplies the blueprint and scaffolding to build better Lyme disease therapeutics that do not have off-target effects for patients,” said Peter Gwynne, PhD, lead author on the study, research assistant professor at Tufts University School of Medicine, and Emerging Leader Award winner of the Bay Area Lyme Foundation. “Many of the 77 genes and enzymes predicted as essential represent candidate targets for the development of novel antiborrelial drug development.”

Current clinical guidelines recommend treatment of Lyme borreliosis with broad-spectrum antibiotics, which can pose risks to the patient’s microbiome. The bacterium that causes Lyme disease is extremely host-dependent, with a small genome and limited metabolism—making it an excellent candidate for the development of targeted, narrow-spectrum antimicrobials.

In the study, the researchers used in silico genome-scale metabolic computer modeling to construct a map of B. burgdorferi metabolism. This map was used to predict essential genes and enzymes that can be used as drug targets. Gwynne and the Tufts University School of Medicine research team validated these targets by repurposing existing drugs that kill B. burgdorferi in culture. While these drugs are not viable treatment options themselves, they provide a blueprint for future novel drug development.

Stealth Invader: Unveiling Lyme’s Hidden Past

By Bay Area Lyme Foundation

Ticktective Podcast Transcript

In this interview, author/filmmaker, Kris Newby, explains the murky history behind the US government’s involvement with Lyme disease and continued efforts to hide how the military’s bioweapons programs caused the spread of tick-borne pathogens. She explains how alliances between pharmaceutical companies, insurance companies, university-based research teams, and the government led to inaccurate testing and denials of care, causing untold suffering to millions. Kris draws parallels between Long Covid and chronic Lyme and shines a light on how we are being dismissed, misinformed, and deliberately misled by the very institutions that should be protecting us.

Dana Parish: I’m so excited to welcome Kris Newby. Kris is an award-winning medical science writer and a senior producer of the Lyme documentary Under Our Skin, which premiered at the Tribeca Film Festival and was a 2010 Oscar Semifinalist. Her book Bitten: The Secret History of Lyme Disease and Biological Weapons has won three international book awards. I loved your book so much for journalism and narrative nonfiction. Kris has two engineering degrees and has worked as a science technology writer for Stanford Medical School, Apple Computer, and other Silicon Valley companies. Welcome Kris!

Kris Newby: Thanks Dana, and thanks for having me on the podcast.

Dana Parish: I’m so excited because you are one of the greatest historians of Lyme and you were so helpful to Steve Phillips and me when we wrote our book, Chronic. We loved your book. And Under Our Skin is the film that informed my view of what was really happening with Lyme disease. You’ve been working on Lyme education for 20 years. You’ve done a film, you’ve written a great book, you’ve published articles, you’ve worked in nonprofits, and you recovered from your own tick-borne diseases. How big is the Lyme problem?

Kris Newby: Ginormous and growing. The CDC’s latest estimate is half a million new cases of Lyme disease a year, and I’m sure everyone remembers when Covid hit a half a million. It was like, “Oh no, we have a problem here.” But for some reason, Lyme disease hasn’t bubbled up as a problem. 500,000 cases a year is an average of 1,300 a day. And, obviously, that mostly happened in the summer, so it’s huge. I am often frustrated because I’ve been working in this field for 20 years and not much has gotten better. The disease—this tick-borne disease—if it’s caught early, it can be cured. But we have a test that isn’t reliable in the first month, and later on it’s no better than a coin flip. About 10-30% of the people who are treated with a recommended treatment—according to what study you read—go on to become chronically ill. And the establishment has invested very little in new treatment protocols. I did an analysis with another Bay Area Lyme person of the NIH grants for the last five years, and less than 1% of the Lyme disease NIH budget is spent on treatments.

BAL Spotlight Series

In this interview, the LymeX Diagnostic Prize talked with Liz Horn, PhD/MDI, Principal Investigator for Bay Area Lyme Foundation’s Lyme Disease Biobank (LDB), about her work in Lyme disease, the challenges researchers face, how the LymeX Diagnostics Prize could help further our understanding of the disease and how Lyme patient samples from our biobank are critical to the competition’s success.

This interview has been edited from the original.

“What’s exciting about the LymeX Diagnostics Prize is that you have a lot of different people with good ideas and different teams with a lot of different technologies trying to solve this problem.”

– Liz Horn, PhD/MDI

The LymeX Diagnostics Prize is a multiphase competition funded by the US Department of Health and Human Services (HHS) and the Steven & Alexandra Cohen Foundation to accelerate the development of Lyme disease diagnostics. Through October 2023, the 10 teams selected to be part of Phase 2 of the LymeX Diagnostics Prize are participating in a virtual accelerator designed to help them refine their concepts for detecting active Lyme disease infections in people. As the Phase 2 accelerator cohort continues to develop their diagnostics, the teams have access to scientific advisors who provide valuable insight and feedback from their extensive experience in Lyme disease diagnostics, one of whom is Dr. Horn. The Phase 2 cohort also has access to the blood and urine samples donated to LDB by Lyme patients.

A cancer biologist by training, Dr. Horn has spent her career working with nonprofit research organizations to help build research programs, registries, and biorepositories. She joined Bay Area Lyme Foundation in 2013 to lead the creation of a Lyme disease biorepository. As a scientific advisor for the LymeX Diagnostics Prize, Dr. Horn is mentoring participating teams through office hours and webinars.

LymeX: As the principal investigator for the Bay Area Lyme Foundation’s Lyme Disease Biobank, you have extensive experience in Lyme disease research. How did you first start working in the field, and what are you focusing on now with the biorepository?
