the tumor

The Tumor Glycocode is the next frontier to break through primary & secondary I/O resistant cancers. A highly selective MoA targeting tumor cells through the Tumor Glycocode that also could be used as novel biomarker in diseases such as colorectal cancer.

We are IND-ready

Since 2021 Gnubiotics has been developing a next generation of immunotherapy and now seeks to progress its lead candidate, GNU101, a promising glycopeptide therapeutic to the next step of IND approval and phase 1 trials.

Gnubiotics Sciences SA is partnering with top-tier academic medical centers to move into first clinical trials.

In case you’re interested to learn more about our clinical development plans and indications, please contact us.

Gnubiotics’ breaking new paradigm is the precise selection of O-glycans conjugated to peptides.
As glycopeptides, they unlock the innate immune system to fight the high unmet need in a variety of conditions.

Our glycopeptides have demonstrated biological proof of concept in activating 4 major biological systems. We have mastered the intelligent, rational design and manufacturing of precise complex glycopeptide biologics that target and affect these biological systems. This resulted in a robust pipeline of first-in-class novel glycopeptide therapeutics that are able to activate the adaptive immune system in a range of cancers and conditions with an unprecedented safety profile.

We are impacting 4 areas of high unmet need
through the GENESIS platform:


I/O resistant cancers

Such as colorectal cancer and triple-negative breast cancer

Immuno-Oncology therapy (I/O) resistant cancers developed numerous ways to evade the body’s immune response. The lead glycopeptide formulation GNU101, specifically promotes cytotoxic T-cell activity in the tumor microenvironment and thus overcomes the tumors resistance. GNU101 has been demonstrated to activate antigen presenting cells to instruct cytotoxic T-cells for mounting a stronger response against I/O resistant CRC cancers. Future glycopeptide formulations can be designed to match the glycocode of targets cancer types.



Such as chronic inflammatory bowel disease

In inflammatory bowel disease, various glycopeptide formulations exhibit dual effects by reinforcing gut epithelial barriers and modulating the local immune response. Notably GNU201 has been demonstrated to enhance a reduction in neutrophils migration to the local mucosal inflammation site. 


Microbiome modulation

Such as recurring Clostridium difficle infections

The glycopeptides developed by Gnubiotics have been demonstrated to intelligently promote microbiome balance by specifically promoting the growth of beneficial bacteria. Thereby enabling resilience to perturbations like antibiotic treatment and growth opportunistic pathogens like recurrent C. difficile


Metabolic syndrome

Such as obesity

Glyopeptide variants developed by Gnubiotics have been demonstrated to reduce the onset of diet induced obesity and enhance thermogenesis through a number of hypothesized mechanisms of action. Gnubiotics is interested in further investigating this promising MoAs through partnerships and collaborations. 

“We are breaking the code, finally uncovering I/O resistant cancers, and activating a targeted & overwhelming T-cell response.”

Dr Yemi Adesokan, CEO

Mechanism of action






GNU101 mediated T-cell response.
Attacking the Tumor Glycocode is a unique first-in-class premise to break through I/O resistance and open a new frontier of novel therapeutics.
