TYK2 Inhibitor Landscape and Pipeline
A new psoriasis treatment, zesacitinib, has been developed using artificial intelligence and is potentially 1.7 million times more precise than current treatments. This episode explores the development and potential impact of zesacitinib, as well as the broader landscape of TYK2 inhibitors and the role of AI in drug discovery.

Key Concepts
TYK2 Inhibitors
- TYK2 is a key switch in the inflammatory cascade
- Inhibiting TYK2 can reduce inflammation and improve symptoms in conditions like psoriasis and psoriatic arthritis
- Allosteric inhibitors like zesacitinib offer high selectivity and reduced risk of off-target effects
AI-Powered Drug Design
- AI algorithms can rapidly sift through and analyze vast virtual libraries of potential drug candidates
- AI can predict the properties of molecules and identify the most promising candidates
- AI-powered drug design can accelerate the development of new treatments and improve their efficacy and safety
Psoriasis and Psoriatic Arthritis
- Psoriasis is a chronic inflammatory skin condition characterized by red, scaly patches
- Psoriatic arthritis is a type of arthritis that occurs in people with psoriasis, causing joint pain and inflammation
- Current treatments for psoriasis and psoriatic arthritis often have limitations and side effects, highlighting the need for new and improved therapies
Benzoyl Peroxide and Benzene
- Benzoyl peroxide is a common ingredient in acne treatments
- Benzene is a known carcinogen that can form in benzoyl peroxide products under certain conditions
- Storing benzoyl peroxide products in the cold and avoiding heat and sunlight can help reduce the formation of benzene
Clinical Trials and Drug Development
- Clinical trials are crucial for testing the safety and efficacy of new treatments
- Phase 2 and phase 3 trials are key stages in the development of new drugs
- Collaboration between researchers, pharmaceutical companies, and regulatory agencies is essential for bringing new treatments to market
Episode Summary
- check_circleZesacitinib is an oral allosteric inhibitor that targets tyrosine kinase 2 (TYK2), a key switch in the inflammatory cascade
- check_circleTYK2 is involved in sending signals for inflammatory messengers like IL-12 and IL-23, which are major drivers of psoriasis and psoriatic arthritis
- check_circleZesacitinib's allosteric mechanism allows for high selectivity, reducing the risk of off-target effects and minimizing collateral damage
- check_circleThe development of zesacitinib involved a collaboration between Takeda, Nimbus Therapeutics, and Schrodinger, and was heavily influenced by AI-powered drug design
- check_circleAI algorithms can rapidly sift through and analyze vast virtual libraries of potential drug candidates, predicting their properties and identifying the most promising molecules
- check_circleZesacitinib has shown encouraging results in phase 2b trials for psoriasis and psoriatic arthritis, with a clean safety profile and significant improvements in symptoms
- check_circleThe phase 3 clinical trials are currently underway, and researchers are also exploring zesacitinib's potential for other inflammatory conditions, such as inflammatory bowel disease
- check_circleOther TYK2 inhibitors, such as ducrevacitinib, are already on the market, but zesacitinib's ultra-high selectivity and pharmacokinetics may give it an advantage
- check_circleThe discovery of benzene in benzoyl peroxide products highlights the importance of ongoing research and informed use, even for common treatments
