Racing Towards AI-first Innovation: From GANs Pioneer to Pharmaceutical Superintelligence
Insilico is at the forefront of generative AI application in life science research, aiming to tackle key scientific and technological challenges in life sciences from first principles using cutting‑edge generative AI. Since its inception, Insilico Medicine is committed to transparency and reproducibility, publishing hundreds of academic papers and presenting at frontier academic and industry conferences.
In 2016, Insilico published a Nature Communications paper, proposing a novel computational method, iPANDA, to address core challenges in biomarker discovery and target-disease associations in omics data analysis. This pathway-based method has since evolved into multiple deep-learning generative algorithms behind Insilico's AI‑powered biological research powering the PandaOmics platform.
In 2019, Insilico's publication in Nature Biotechnology described how its proprietary deep generative model, GENTRL, was used to discover a potent inhibitor of the kinase target DDR1. It took only 21 days from target identification to the generation of a molecule with drug‑like properties. This study is regarded as one of the landmark events in the rise of AI‑driven drug discovery and laid an important academic foundation for the widespread adoption of generative AI in drug discovery and development.
These two early academic papers, along with a series of other published fundamental research, laid a solid foundation for Insilico to build Pharma.AI, its integrated end‑to‑end platform spanning biology, generative chemistry, clinical development and scientific research.
In 2025 alone, Insilico Medicine scientists published 9 papers in Nature-family journals and 10 papers in the American Chemical Society's Journal of Medicinal Chemistry.
Since 2020, the Pharma.AI platform has been launched and commercialized as a modular software suite, and its collaboration network has expanded globally. As of the latest practicable date, Insilico has entered into software licensing collaborations with 13 of the world's top 20 largest pharmaceutical companies.
By continuously iterating its algorithms, building proprietary multimodal data warehouses, and improving infrastructure and tooling, Insilico has consistently optimized the performance of the Pharma.AI platform and extended its capabilities into emerging areas such as sustainable chemistry and agriculture, driving deep integration of AI‑driven innovation across the entire life science value chain.
In December 2022, Life Star 1, the industry's first fully automated biology laboratory independently constructed by Insilico, was officially put into operation. Highly integrated with Insilico's AI platform, the lab closes the loop from in silico design to experimental validation, enabling a highly efficient "lights‑out factory" capable of unmanned operation. While supporting wet‑lab validation for both internal and partnered projects, it continuously accumulates high‑quality proprietary datasets to further power the evolution of the AI platform. In September 2025, the upgraded Life Star 2 was officially launched with significantly enhanced cross‑island equipment coordination and multi‑workflow parallel processing capabilities, establishing a more convenient, stable and highly scalable intelligent lab system through refined allocation algorithms and response mechanisms.
In 2025, Insilico first proposed the concept of Pharmaceutical Superintelligence, defining it as the next stage of AI‑driven drug R&D, which aims at a fully AI‑driven, autonomous, and intelligent system for drug discovery and development. Insilico's experimentally-validated purpose-built models can now be used to make other frontier multimodal models including third-party models more intelligent and capable in multiple scientific discovery tasks.
Global Leading AI R&D Capabilities: From First AIDD Milestone to Global Benchmarks
By integrating its proprietary AI‑enabled drug discovery platform with advanced automated laboratory capabilities, Insilico has significantly improved the efficiency of drug R&D in practice. It has not only delivered pioneering innovation milestones, but also established a benchmark for AI‑driven drug discovery. Compared with the average of 4.5 years typically required for traditional early‑stage drug R&D, Insilico reduced the average time from program initiation to preclinical candidate (PCC) nomination to 12–18 months across more than 20 in‑house programs between 2021 and 2024, with only 60–200 molecules synthesized and tested per program.
The most representative example is Rentosertib (ISM001‑055), a novel mechanism‑of‑action candidate for idiopathic pulmonary fibrosis (IPF) empowered by AI. This program is considered the most advanced first‑in‑class AI‑discovered drug currently in development. Insilico completed the early discovery phase in just 18 months and identified the PCC after screening and testing only 78 molecules. The AI‑driven R&D journey of this program, from target discovery and molecule design through to Phase I clinical studies, was published in Nature Biotechnology in March 2024, providing the first systematic demonstration of an AI‑enabled, end‑to‑end drug discovery process from scratch.
Also in 2024, Insilico completed the China Phase IIa clinical trial for Rentosertib, with favorable safety and tolerability demonstrated, as well as an emerging dose‑dependent efficacy trend in IPF patients, indicating the potential to reverse the disease progression. The results were published in Nature Medicine in May 2025 and are regarded as the first clinical proof‑of‑concept milestone in the AI drug discovery field, providing valid practical evidence for AI‑driven drug discovery.
In addition, Insilico continues to extend its specialized AI‑driven capabilities into more areas of high unmet medical needs, building a structured portfolio of more than 30 programs centered around key therapeutic areas including fibrosis, oncology, immunology, inflammation, cardiometabolics and central nervous system (CNS) disease. Among all the innovative pipelines, 10 have received IND clearance, 7 of them are currently in active clinical development.
Meanwhile, AI‑driven R&D collaborations and pipeline out‑licensing are expanding. As of the latest practicable date, Insilico has achieved 3 out‑licensing deals with global pharmaceutical companies including Exelixis and Menarini, with the maximum total deal value up to$2.1 billion. Furthermore, co‑development partnerships with global pharma leaders including Fosun Pharma, Sanofi and Lilly provide solid validation and powerful boost for the value of AI applications in the global drug discovery industry.
