Lumen’s immunotherapy (mAb) targets pathogens that are a major cause of death of infants and children in low- and middle-income countries (LMICs)

(BOSTON: January 27, 2021) – CARB-X is awarding up to US$5.35 million to Lumen Bioscience, in Seattle, WA, USA, to develop a new immunotherapy to prevent diarrheal diseases caused by two deadly pathogens, Campylobacter jejuni and enterotoxigenic E. coli. The project could be eligible for up to $8.26 million more in non-dilutive funding from CARB-X if project milestones are met, subject to available funds.

Diarrheal diseases are often referred to as traveller’s diarrhea – intestinal infections caused by contaminated food or water. While unpleasant, most healthy adults survive. However, in low- and middle-income countries (LMICs), diarrhea is a leading cause of death and disease among infants and children.

Diarrhea kills 2,195 children every day—more than AIDS, malaria, and measles combined, according to the US Centers for Disease Control and Prevention (CDC). Diarrheal diseases account for 1 in 9 child deaths worldwide, making diarrhea the second leading cause of death among children under the age of 5. It causes death by depleting body fluids, resulting in profound dehydration.

“Preventatives are urgently needed for deadly infections,” said Erin Duffy, R&D Chief of CARB-X, a global non-profit partnership led by Boston University and dedicated to funding and supporting the development of innovative products to address antibiotic-resistant bacterial infections. “The Lumen project is an extremely innovative immunotherapy in the early phases of development, and if successful, could potentially transform the way we prevent deadly infections in infants and children, and save precious lives.”

“The ability to effectively prevent and treat diarrheal diseases, which have devastating impacts in the developing world, has been compounded by the sheer scale and costs inherent in traditional drug development,” said Jim Roberts, M.D., Ph.D., co-founder and Chief Scientific Officer of Lumen Bioscience. “Our unique approach offers the potential to provide an effective approach at a low cost and mass scale, and we are grateful for the support from CARB-X to help advance this promising approach.”

The project, LMN-GI-EEC-401, is an oral antibiotic-alternative biologic developed with Lumen’s proprietary manufacturing process that utilizes spirulina expression. The goal is to produce a food-grade immuno-prophylactic drug at low cost for use around the world, including in areas where health-care temperature control is not available.

The Lumen work is being done in collaboration with the US Naval Medical Research Center, led by Frederic Poly; Tufts University in Boston, led by Charles Shoemaker; the University of Virginia, led by Jim Nataro; and A-Alpha Bio, Inc., a Seattle-based biotechnology start-up.

CARB-X receives its funding from the US Biomedical Advanced Research and Development Authority (BARDA), the Wellcome Trust in the UK, the UK Global Antimicrobial Resistance (AMR) Innovation Fund (GAMRIF), Germany’s Federal Ministry of Education and Research (BMBF), and the Bill & Melinda Gates Foundation. The funding contributions by GAMRIF and the Gates Foundation are earmarked by CARB-X to fund projects that focus on specific antibacterial priorities, and the Lumen project is one such project. Gates Foundation funds received by CARB-X are allocated to the development of vaccines and novel biologics to avert drug-resistant diseases and protect the lives of children and infants, especially in LMICs. GAMRIF funding allocated to CARB-X is focused on innovative research and development in the field of AMR, specifically in neglected and underinvested areas for LMICs, where the burden of AMR is greatest.

Supporting global antibacterial innovation to address drug resistance  

The World Health Organization (WHO) estimates that 700,000 people die each year from drug-resistant infections, including 35,000 in the US and 33,000 in Europe. CARB-X funds only projects that target drug-resistant bacteria highlighted on the Center for Disease Control and Prevention (CDC)’s Antibiotic Resistant Threats list, or the Priority Bacterial Pathogens list published by the WHO, with a priority on those pathogens deemed Serious or Urgent on the CDC list, or ranked Critical or High on the WHO list.

The CARB-X portfolio is the world’s largest and most diverse antibacterial R&D portfolio with 50 active projects focused exclusively on drug-resistant bacteria. CARB-X is investing up to $480 million in non-dilutive funding between 2016-2022 to support the early development of new antibiotics and other therapeutics, vaccines and other preventatives, rapid diagnostics. The goal is to support therapeutics projects through the early phases of development including Phase 1 so that they will attract additional private or public support for further clinical development and regulatory approval for use in patients.

Since its launch in 2016, CARB-X has announced 76 awards and has committed more than $260 million, with the potential of additional funds if project milestones are met. These funds are in addition to investments made by the companies themselves. The CARB-X pipeline will continuously evolve, as projects progress and others fail for a variety of reasons.
