Artificial intelligence is being applied to every stage of this process: identifying biological targets, designing molecules, predicting toxicity, selecting patients and personalising treatment. In 2026, two programmes provided the clearest clinical evidence yet of what this approach can achieve. ## How AI discovers drugs AI drug discovery typically proceeds in two stages. First, **target discovery**: models analyse genomic, proteomic and clinical data to identify proteins that drive a disease. Second, **generative chemistry**: models trained on known molecules and their properties propose new chemical structures predicted to bind the target, be safe and be manufacturable. Promising candidates are synthesised and tested in the laboratory, and the results feed back into the models. This cycle can compress years of medicinal chemistry into months. ## Rentosertib: an AI-discovered drug in phase III Insilico Medicine used its generative AI platform both to identify the target, the kinase **TNIK**, and to design the molecule **rentosertib** for idiopathic pulmonary fibrosis (IPF), a progressive scarring of the lungs. In a phase IIa study, patients receiving 60 mg once daily showed a **mean improvement in forced vital capacity (FVC) of 98.4 mL after 12 weeks, compared with a mean decline of 20.3 mL on placebo**. In 2026 the company launched the phase III **GENESIS-IPF-3** trial, a randomised, double-blind, placebo-controlled study of 320 patients at 47 centres over 52 weeks, and dosed the first patient in September 2026 (News-Medical, 2026; Bio-IT World, 2026). ## Personalised mRNA cancer vaccines Every tumour carries mutations that produce abnormal proteins, called **neoantigens**, which the immune system can learn to recognise. A personalised cancer vaccine is designed for a single patient: the tumour and healthy tissue are sequenced, algorithms identify and rank the neoantigens most likely to trigger an immune response, and an mRNA vaccine encoding them is manufactured for that patient. Moderna's intismeran autogene encodes up to 34 neoantigens. In August 2026, Moderna and Merck announced that the phase III **INTerpath-001** trial of intismeran autogene combined with the immunotherapy Keytruda met its primary endpoint of **recurrence-free survival** and its key secondary endpoint of **distant metastasis-free survival** in 1,137 patients with resected high-risk melanoma (BioPharm International, 2026). Five-year data from the earlier phase IIb study showed a 49% reduction in the risk of recurrence or death (hazard ratio 0.51). ## AI across the medicine lifecycle - **Vaccination programmes**: forecasting demand, optimising cold-chain logistics and identifying under-vaccinated populations. - **Medicine assistants**: explaining prescriptions, checking interactions and supporting adherence for patients. - **Clinical trials**: matching patients to trials and predicting enrolment and outcomes. ## Brand opportunity: biotech and health domains **AiDrug.ai** is a category-defining name for an AI drug discovery company or platform. **CancerVaccines.ai** fits a biotech, a patient information service or an investment platform focused on personalised oncology. **MyDrug.ai** suits a personal medicine assistant, **Immunization.ai** a vaccination intelligence service, and **IVG.ai** a short brand for a biotech or health technology company.

Yes. Insilico Medicine’s rentosertib, whose target and molecule were both found with generative AI, entered the phase III GENESIS-IPF-3 trial for idiopathic pulmonary fibrosis in 2026. ### What is a personalised cancer vaccine? A vaccine designed for one patient: the tumour is sequenced, algorithms select its most immunogenic neoantigens, and an mRNA vaccine encoding them trains the immune system to attack the cancer. ### Is AiDrug.ai for sale?
