SEATTLE, Oct. 6, 2021 /PRNewswire/ -- Lumen Bioscience—a clinical-stage biopharmaceutical company developing biologic drugs for highly prevalent diseases—today announced new development funding from the US Army for its Covid-19 monoclonal antibody drug cocktail. The support is provided by the US Army Medical Research and Development Command (USAMRDC), operating through the Medical Technology Enterprise Consortium (MTEC).

This announcement builds on a previous Army grant to Lumen that funded preclinical development of LMN-301, an investigational product directed at treating and preventing the gastrointestinal (GI) manifestations of Covid-19. These symptoms are an important aspect of the disease but have received less attention than the respiratory and immunological aspects due to the lack of scalable technologies for treating such infections. Lumen's spirulina-based GMP manufacturing and delivery technology is uniquely suited for such applications.

"Everyone knows about the respiratory symptoms of Covid-19, but it's less well appreciated among non-specialists that a majority of patients also endure GI-related issues, which can be quite severe," said Brian Finrow, Lumen's co-founder and CEO. "A therapeutic targeting this source of infection could reduce the viral load, inhibit disease progression, and potentially eliminate a significant source of disease transmission. Our unique biologics platform is the first to potentially allow for the cost-effective manufacturing of therapeutic proteins at pandemic scale, so we're pleased to have this opportunity to contribute to the fight against Covid-19."

It has been definitely established that the virus infects the GI tract and leading studies show that such symptoms appear in a majority of patients with Covid-19. The Lumen Bio product under development, LMN-301, is a cocktail of antibody-like proteins that bind to the spike protein of SARS-CoV-2 and prevent it from infecting the ACE2-presenting cells that line the GI tract. The contract extension will fully fund a Phase 2 clinical trial among Covid-19 patients. A portion of the funds will also support a significant expansion of Lumen's existing cGMP manufacturing plant.

Lumen plans to carry out the clinical trial in Brazil in collaboration with the widely respected TOGETHER Trial research consortium. This consortium was established with funding support from FastGrants, the Bill & Melinda Gates Foundation and the Rainwater Charitable Foundation, and is led by Dr. Edward Mills and Dr. Gilmar Reis.

"Like other researchers, we have noticed a significant prevalence of GI symptoms in the thousands of Covid-19 patient volunteers that have proceeded through the TOGETHER umbrella clinical trial to date", said Dr. Mills "These symptoms are severe in some patients, and so we are excited to have this shot at making a difference in the patients' lives with LMN-301."

The Phase 2 clinical trial is expected to commence enrollment in late winter following clearance by regulators and research ethics committees.

About GI Infection and Covid-19

The "respiratory" virus that causes Covid-19 also infects the GI tract. In one widely cited study,1 a majority of Covid-19 patients presented with both GI and respiratory symptoms, and 25% had only GI symptoms. These symptoms can be both severe and wide-ranging2, in some cases requiring surgical resection3. GI infection by the virus is also thought to contribute to liver damage4 and acute respiratory distress syndrome (ARDS)5, both common long-term symptoms of severe Covid-19. This is not surprising: 25% of MERS6 cases and 16-73% of SARS7 cases in the 2002-2003 outbreak also presented with significant GI symptoms, and it is widely accepted that the original 2003 SARS virus transmitted efficiently through the fecal-oral route8, a phenomenon that could also explain recurring Covid-19 superclusters. Indeed, though researchers' ability to definitively nail down the source of any particular case of transmission to a particular transmission route, several groups have published studies documenting transmission under circumstances that strongly implicate GI transmission.9,10,11 Lumen's GI-targeted therapy may therefore not only reduce overall viral burden, inhibit disease progression, and accelerate recovery, but also prevent a potentially significant source of Covid-19 transmission.
