Bill & Melinda Gates Foundation, Department of Defense and CARB-X Back Further Development of Spirulina-Based Therapeutics

Seattle, WA, January 4, 2023 – Lumen Bioscience, a clinical-stage biotechnology company developing biologic drugs for highly prevalent diseases, today announced several funding milestones supporting the development of its therapeutics to prevent serious diarrheal diseases.

The first is a $5 million grant from the Bill & Melinda Gates Foundation for a second Phase 2 study of an improved anti-campylobacter therapeutic, LMN-101. The randomized, double-blind, placebo-controlled study will evaluate LMN-101 at several dose levels in healthy volunteers challenged with Campylobacter jejuni CG8421. The trial design is similar to the first Phase 2 trial of LMN-101 but with enhancements to shed light on the unexpectedly low placebo attack rate that made that earlier trial uninterpretable.

The second milestone is a new $4 million award from the US Army Medical Research and Development Command (USAMRDC), operating through the Medical Technology Enterprise Consortium (MTEC), for further clinical evaluation of Lumen’s anti-campylobacter/anti-ETEC VHH cocktail product. Building on foundational work at Lumen that was originally funded by Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X), the new funds will support clinical evaluation of a tablet form of the product, which is expected to have favorable cost and distribution characteristics compared with the capsule format tested in past trials. The grant will also be used to further characterize the product’s gastrointestinal pharmacokinetics in study volunteers.

Finally, Lumen is pleased to announce that CARB-X has also renewed its funding support with an additional award of up to $2.8 million for lead optimization of an anti-campylobacter/anti-ETEC VHH cocktail to prevent serious diarrheal diseases.

“Lumen Bioscience is dedicated to developing innovative solutions to some of the world’s most pressing healthcare challenges. In addition to making life miserable for travelers and deployed servicemen and women, diarrheal infections are a major cause of infant mortality and morbidity in the developing world. The new funding from the Gates Foundation, USAMRDC, and CARB-X will help advance the company’s work in these areas, and we are grateful for their support,” said Brian Finrow, CEO of Lumen Bioscience.

“Overall, these developments represent major progress for Lumen, and we are excited to continue our work in these areas,” said Jim Roberts, Lumen’s Chief Scientific Officer. “We look forward to sharing the results of these studies with the scientific community and the public as the program progresses.”
