Unraveling The Microbiota For Gut Health

About Biotagenics

Biotagenics is a clinical microbiomics company developing therapeutics and companion diagnostics for the management and treatment of diseases associated with microbiota dysbiosis. Our initial focus is Inflammatory Bowel Disease.

We are biopharmaceutical executives, microbiologists, immunologists, and gastroenterologists. Our microbiomics platform is coupled with extensive clinical correlative data as well as metagenomic and metaproteomic analyses of patient samples.

Biotagenics is identifying therapeutic targets that have the potential to restore symbiosis and modify the course of disease. Our therapeutic strategy is based on precision targeting of the microbiome using our validated recombinant antibody technology.

About IBD

Ulcerative Colitis and Crohns’ Disease (collectively referred to as IBD) are severe GI disorders caused by inflammation.

Both conditions are significant unmet medical needs of increasing incidence and frequent patient hospitalizations.

The human microbiome is a key functional component to disease and human health. Recent advances in high-throughput sequencing have opened up the opportunity to use this dynamic collection of bacteria as a diagnostic and therapeutic target.

Biotagenics has developed proprietary biomarker discovery platform using specialized methods to analyze genome and proteome of the intestinal microbial ecosystems.

Utilizing our biobank of pediatric IBD intestinal and stool samples along with our single-domain antibody discovery platform, we aim to commercialize novel diagnostics and highly specific therapeutics that target bacteria associated with the disease conditions.

Our Platform

Biotagenics has assembled a platform to develop pathobiont-specific biologics and companion diagnostics. Our powerful metagenomics, proteomics, and metabolomics discovery platform combined with unique, clinically well-defined tissue biobanks allows generation of diagnostics and effective treatment for IBD.

Platform for discovery of IBD targets and fundamental mechanisms of IBD etiology and disease sequelae
IBD Diagnostics
Biomarkers for IBD diagnosis; Stratification of patients into subtypes, Crohn’s disease (CD) and ulcerative colitis (UC)
IBD Therapeutics
Recombinant antibodies and peptides; Validated platform to develop gut-targeted biologics against specific bacterial species


Biotagenics has secured an exclusive, worldwide license to the technologies developed by our Founders at the University of Ottawa. Biotagenics continues to collaborate with the University of Ottawa and Children’s Hospital of Eastern Ontario Research Institute to develop these technologies and discover new diagnostic and therapeutic opportunities in IBD and other diseases mediated by dysbiosis.

As of 2017, Biotagenics has entered into a strategic R&D partnership with Filament Biosolutions to explore the interface of clinical nutrition and the microbiome. Filament is a US-based clinical nutrition company with expertise in product development, regulatory strategy, clinical trial design & execution, and commercialization. Filament also has deep expertise in in-licensing of assets and IP strategy. This collaboration will lead to the development of advanced therapeutics and nutritional therapies, focused initially on IBD but with subsequent expansion into additional disease indications and conditions.

Biotagenics is actively seeking innovative technologies and opportunities for industry partnerships.
