Lumen Bioscience

We’ve Reinvented How Biologic
Drugs Are Made

Lumen’s patented technology allows us to use the well-known food algae spirulina to deliver therapeutic proteins.

Unrivaled Speed, Safety, And
Effectiveness

Our patented technology allows us to develop biologic drugs faster and with lower cost and risk than traditional methods.

More About Our Science

How It Works

01

The Organism

Being extraordinarily high in soluble protein, spirulina cells are able to express far higher amounts of therapeutic proteins than any other food crop (>60%).

02

Engineering

A gene encoding the therapeutic molecule (for example, an antibody) is introduced into the spirulina chromosome.

03

Production

The production system requires only water, salt, CO₂ and light, so it is cheap and rapidly scalable.

04

Delivery

This powder can be packed into dose-speciﬁc capsules, which don't require refrigeration and are shelf-stable at room temperature.

Neglected No More

Many highly prevalent diseases have proven impossible to treat with traditional drug-making tools, despite decades of research, so they’ve been essentially abandoned by drug makers. Lumen’s unique technology is ideally suited to finally address these indications.

C. difficile (LMN-201)

Oral biologic cocktail

Product Candidate

C. difficile Colitis

(Clostridioides difficile)

Initiated Spring 2018

Mode of action: Cocktail of biologics; two formats

Phase 1

Traditionally considered a hospital-acquired infection, C. difficile is more commonly community - required today. For this reason, the shelf-stable, orally delivered format of Lumen’s product is an important addition to the tool kit for treating and preventing this disease. Long-term consequences include chronic diarrhea, severe intestinal inflammation, surgical resection, and death. Insidiously, the very thing that is used to treat this infection—broad spectrum antibiotics—is also the thing that causes the disease. . C. difficile therefore appears at the top of the CDC’s antimicrobial threats list year after year, and in 2009 was estimated to single-handedly drive 2.3% of all US hospital costs.

IBD (Crohn’s/UC)

Oral biologic cocktail

Product Candidate

IBD

(Crohn's disease and ulcerative colitis)

Initiated Summer 2021

Mode of action: Biologic cocktail

Preclinical

Inflammatory bowel disease (IBD) is a systemic autoimmune disease, but it has an obvious nexus with the gastrointestinal tract. The two main sub-varieties—Crohn’s disease and ulcerative colitis—have many available treatments on the market today, but it remains a major unmet medical need: current treatments are costly, require inconvenient injection delivery, and come with severe side effects. There are no approved therapies at all for mild-to-moderate Crohn’s. A safe, affordable, orally delivered drug to root out IBD at its source is a straightforward application of Lumen's technology, and would constitute a major advance for the field.

IND Prep

Covid-19 is widely known as a respiratory disease, but its GI symptoms are well documented. The now-famous ACE2 receptor is abundantly expressed on the cells lining the GI tract, and over half of Covid-19 sufferers show symptoms of GI distress, and up to a quarter show only GI symptoms. GI infection by the virus can have serious long-term effects, and high enteric viral loads are thought to contribute to fatalities from acute respiratory distress syndrome (ARDS) and wet-lung disease. Lumen’s Covid-19 product is designed to block GI infection and rapidly flush the virus from the GI tract, thereby reducing disease symptoms and potentially reducing transmission rates.
