Protagonist Therapeutics: Transforming Drug Discovery with DeuteRx Technology

Introduction

Protagonist Therapeutics is a clinical-stage biotechnology company pioneering a transformative platform technology called DeuteRx. DeuteRx enables the creation of improved therapeutics with enhanced potency, selectivity, and safety profiles.

DeuteRx Technology

DeuteRx is a precision medicine approach that involves the site-specific incorporation of deuterium, a heavy isotope of hydrogen, into small molecule drugs. By strategically replacing hydrogen atoms with deuterium, Protagonist Therapeutics can tune the properties of drugs, optimizing their interactions with biological targets.

Enhanced Potency and Selectivity

Deuteration can significantly enhance the affinity of drugs for their targets. By increasing the binding time between the drug and the target, DeuteRx-enabled drugs can achieve greater potency with lower doses. Additionally, deuteration can improve selectivity by reducing off-target interactions, minimizing adverse effects.

Improved Pharmacokinetic Properties

Deuteration can also improve pharmacokinetic properties by reducing metabolic clearance. By replacing hydrogen atoms with deuterium, the drug's metabolism is slowed down, resulting in longer half-lives and more sustained therapeutic effects.

Proprietary Platform

Protagonist Therapeutics has developed a proprietary DeuteRx platform that provides precise control over the location and extent of deuterium incorporation. This platform allows for the systematic design and optimization of DeuteRx-enabled drugs.

Clinical Pipeline

Protagonist Therapeutics has a robust clinical pipeline of DeuteRx-enabled drugs targeting various therapeutic areas, including immunology, oncology, and respiratory diseases. Key candidates include:

• PTG-200: A deuterated allosteric tyrosine kinase 2 (TYK2) inhibitor for the treatment of psoriasis and inflammatory bowel disease.
• PTG-300: A deuterated glucagon-like peptide-1 (GLP-1) receptor agonist for the treatment of type 2 diabetes.
• PTG-100: A deuterated angiotensin receptor blocker (ARB) for the treatment of hypertension.

Conclusion

Protagonist Therapeutics is a leading biotechnology company at the forefront of drug discovery innovation with its transformative DeuteRx technology. By optimizing the properties of small molecule drugs, DeuteRx has the potential to revolutionize treatment paradigms and improve patient outcomes. Protagonist Therapeutics' robust clinical pipeline holds promise for addressing unmet medical needs and advancing healthcare for patients worldwide.
