An AI-Discovered Drug Succeeds in Phase III Trials!
2023Year, Takeda with40Acquisition with a down payment of hundreds of millions of US dollarsNimbusofTYK2Drug,and renamed tozasocitinib(TAK-279)。
Last night, Takeda announced thisTYK2Drugthe latestIIIPhase clinical information. Data show that the drug head-to-headHeadEfficacy Directly Outperforms BMS’s Same-Target Drug Sotyktu!
Top-line results show that,Zasocitib at the primary endpoint, i.e., PASI 100 response rate at Week 16as high as 33.4%, whereas it was 14% among patients treated with Sotyktu.
That is to say, inNo.16ZhouIn terms of the proportion of patients with complete clearance of skin lesions,The efficacy of Zasocitinib is more than 2.5 times that of Sotyktu.。
The study also shows that,Zasocitinib was superior to the active control across all key secondary endpoints, including PASI 90 response and a static Physician’s Global Assessment (sPGA) score of 0 at Week 16. Zasocitinib was generally well tolerated, with no new safety signals identified.
Takeda plans to2027First Half of the YearYear,PlacezasocitinibOfficially launched in the market.
For Takeda, the $4 billion gamble is finally paying off.

BIC Drug Targeting TYK2
TYK2YesJAKA member of the kinase family that plays a central role in the signaling of multiple key inflammatory cytokines。
2022Year9Month, Bristol-Myers SquibbofTYK2Allosteric inhibitor deucravatinib (deucravacitinib, with the trade nameSotyktu) marketing application for the treatment of plaque psoriasis approvedFDAApproved.
Thus,SotyktuBecomeThe world's first approved and marketedTYK2Inhibitor。
BMSInitially forSotyktuwith peak sales forecasts reaching as high as40hundred million US dollars, however, the reality is thatIts2025global annual total sales amounted to only2.91$100 million,The U.S. market also experienced a decline.。
The reason is that the competition in the psoriasis market is extremely intense; despite the advantages of oral administration, the efficacy and current maincompared to mainstream biologicsA significant gap remains, making it difficult to challenge the latter’s status as the gold standard.。
In contrast,Zasocitinibis aCalculate the predicted sumDesignedSmallMoleculeDrug,PossessingBICpotential.
This drug was initiallybyNimbus TherapeuticsandAICo-developed by Schrödinger Pharmaceuticals, thereby obtaining targetedTYK2highly selective drugs.
ZasocitinibAs aHighly Selective OralTYK2Inhibitor, can maintainIL-23and other core immune signaling pathways driving the disease24Hourly inhibition.
Based on in vitro data, compared to otherJAKCompared with enzymes,zasocitinibYesTYK2with over -fold higher selectivity10010,000-fold, which may not affectJAK1、JAK2andJAK3In the context of signal transduction, maximizeTYK2Inhibition.
2022years, based on goodIIbPhase data,Takeda60Acquisition for Hundreds of Millions of US DollarsThisTYK2Inhibitor, Prepaid40hundred million U.S. dollars.
Transaction stipulates that, subsequently based on post-launch sales revenue of the drug,NimbusHave the opportunity to obtain again20billion-dollar revenue share.

Computation-driven,Distinct from Traditional R&D Approaches
2009Year,Atlas VenturePartnerBruce Booth, combined with SchrödingerCEO Ramy Farid, co-foundedNimbus Therapeutics。
Since its inception, the company has transcended the traditional framework of drug development.
NimbusLarge-scale adoption of the Schrödinger computational platform, leveraging physics-based principles to guide drug development decisions and bypassing the traditional trial-and-error approach to drug discovery.
The core of this model is dual deep collaboration: first, the coordinated efforts of teams from both companies; second, the deep integration of medicinal chemistry and computational chemistry talent. In the traditional R&D framework of the industry, these two roles have long been siloed, whereasNimbusIntegrating these elements to create a proprietary competitive advantage.
The core R&D philosophy of the team is computation-driven drug design. The entire R&D process relies heavily onCalculationTechnical modeling and prediction, rather than the trial-and-error approach of traditional models.
Preclinical compound synthesis and testing, guided primarily by modeling results, represent a significant innovation in drug development paradigms.
AtTYK2Inhibitorin the research and development, the team extensively utilizedFEP+WaitSimulation technology,TargetingTYK2A specific site on the proteinJH2DomainConduct targeted therapy。
The results of this technologyRapidly predict the effects of molecules,The result was that a candidate molecule with super-high potency (at the picomolar level) was identified in just about three months.
Finally, the teamwhile optimizing its drug-like properties (such as stability and absorption), ultimately leading to the successful identification of a drug candidatezasocitinib。
PreviouslyMost pharmaceutical companies are unable to implement computational drug discovery and development at scale, whileNimbusThis has been achieved, with the full implementation of a computational R&D philosophy and empowering teams to lead R&D decisions through technology, which holds revolutionary significance in the field of drug development.

What other late-stageAIDrugs Worth Noting?
