近年来AI制药赛道热度持续走高,大量生成式AI平台参与靶点挖掘、全新分子从头设计,一批候选药物陆续推进人体临床试验。截至2026年9月,全球尚无完全由AI设计的创新药正式获批上市,但10款代表性候选药物已经走到临床关键阶段,成为行业验证AI药物研发价值的核心样本。
Rentosertib(ISM001‑055),英矽智能,项目启动于2020年,针对特发性肺纤维化,目前处于III期临床。该药物靶点与分子全部由生成式AI完成发现与设计,IIa期临床证实可改善患者肺活量指标,国内CDE授予突破性疗法认定,是全球端到端AI研发进度最快的小分子药物。
REC‑4881,Recursion Pharmaceuticals(美国),项目启动2021年,用于家族性腺瘤性息肉病,处于II期临床,AI表型筛选得到MAP4K4抑制剂,II期数据显示患者息肉显著下降。
GB‑0895,Generate:Biomedicines(美国),项目启动2020年,适应症重度哮喘,现已进入III期临床,不依赖天然抗体库,也是全球进度最快的AI原创抗体药物。
SGR‑1505,Schrödinger(美国),项目2020年启动,用于复发难治B细胞淋巴瘤,处于I期临床,借助物理‑AI模拟快速完成全新分子设计,I期观察到初步肿瘤缓解信号。
SIGX‑1094,晶泰科技(中国)与Signet Therapeutics(美国),2021年启动项目,针对弥漫型胃癌,处于I期临床,拿到FDA孤儿药与快速通道资格。
IAM‑1363,Iambic Therapeutics(美国),2022年立项,针对HER2变异实体瘤,I/1b期临床,AI生成的小分子激酶抑制剂,早期临床取得部分缓解案例。
ABS‑101,Absci(美国),2021年启动,适应症炎症性肠病,处于I期临床,无需动物免疫即可生成全新抗体序列。
ISM‑6331,英矽智能,2021年立项,治疗晚期间皮瘤,I期临床,获得FDA快速通道资格,AI识别Pan‑TEAD全新靶点并生成小分子。
DSP‑0038,Exscientia(英国,现归属Recursion),2020年启动,针对阿尔茨海默病精神行为症状,处于I期临床,从分子设计到候选分子确认仅耗时13个月,是这批项目中研发时间压缩幅度最大的管线。
ATM‑3507,Atomwise(美国),2019年启动,用于多发性硬化,I期临床,AI虚拟筛选得到全新骨架分子,攻克难成药靶点。
整体来看,这批项目大多集中在2019‑2022年间立项。AI显著压缩靶点发现、分子设计的早期周期,但行业现实是:早期发现环节成本下降,算力、AI平台建设、临床试验投入依然高昂,新药整体开发总费用并未出现整体性大幅下降。全部候选药尚未完成注册上市,AI设计分子的安全性、长期有效性仍需要大规模临床试验最终确认。
Ten Fastest‑Advancing AI‑Designed Pharmaceutical Candidates
The AI‑driven drug‑discovery sector has expanded rapidly in recent years. Generative‑AI platforms are widely deployed for target identification and de‑novo molecule design, bringing multiple candidate drugs into human clinical trials. As of September2026, no fully AI‑originated therapeutics have obtained global regulatory approval. Nevertheless, ten representative drug candidates have reached key clinical stages, serving as critical case studies for validating the real‑world value of‑AI‑powered drug development.
Rentosertib (ISM001‑055), developed by Hong‑Kong‑based Insilico Medicine, was initiated in 2020 for idiopathic pulmonary fibrosis and is currently in PhaseIII trials. Both its therapeutic target and molecular structure are entirely discovered and designed via generative AI. PhaseIIa data have proven its capacity to stabilize patients’ forced vital capacity, and China’s CDE has granted it breakthrough‑therapy designation, making it the most advanced end‑to‑end AI‑developed small‑molecule drug worldwide.
REC‑4881 from US‑based Recursion Pharmaceuticals launched in 2021 for familial adenomatous polyposis and is undergoing PhaseII trials. An AI phenotypic screen identified the MAP4K4 inhibitor, and PhaseII results have demonstrated substantial polyp reduction in patients.
GB‑0895, created by US‑based Generate:Biomedicines, started in 2020 for severe asthma and has progressed to PhaseIII trials. This antibody is built entirely through generative AI without reliance on natural antibody libraries, representing the most advanced original AI‑generated antibody candidate globally.
SGR‑1505 from Schrödinger (United States) kicked off in 2020 for relapsed or refractory B‑cell lymphoma and is in PhaseI trials. Physics‑based AI simulations accelerated de‑novo molecule construction, and preliminary anti‑tumor responses have been observed in early‑stage subjects.
SIGX‑1094, jointly developed by China‑based XtalPi and US‑based Signet Therapeutics, began in 2021 for diffuse‑type gastric cancer and is in PhaseI trials with FDA orphan‑drug and Fast‑Track designations.
IAM‑1363 by US‑based Iambic Therapeutics was initiated in 2022 for HER2‑mutated solid tumors and is undergoing PhaseI/1b trials. This AI‑generated small‑molecule tyrosine‑kinase inhibitor has yielded partial tumor responses in early‑stage patients.
ABS‑101 from US‑based Absci launched in 2021 for inflammatory bowel disease and is in PhaseI trials, with novel antibody sequences produced by AI without animal immunization.
ISM‑6331, another pipeline asset of Insilico Medicine, started in 2021 for advanced mesothelioma and is in PhaseI trials with FDA Fast‑Track designation; generative AI uncovered the novel Pan‑TEAD target and corresponding small‑molecule candidates.
DSP‑0038, developed by UK‑based Exscientia (now part of Recursion), commenced in 2020 to manage behavioral and psychological symptoms of Alzheimer’s disease and is in PhaseI trials. It took merely 13months to move from molecular design to candidate selection, marking the most drastic timeline compression among the listed programs.
ATM‑3507 from US‑based Atomwise began in 2019 for multiple sclerosis and is undergoing PhaseI trials. AI virtual screening delivered novel‑scaffold molecules to target traditionally undruggable sites.
Most of these projects were initiated between 2019 and 2022. AI has greatly shortened timelines for target identification and molecular design in early‑stage research. That said, while early‑phase discovery costs have decreased, expenses related to AI infrastructure construction and clinical trials remain substantial, so overall drug‑development expenditures have not seen a broad‑based decline. None of these candidates have completed registration‑approval procedures to date, and large‑scale clinical trials are still required to verify the long‑term safety and efficacy of AI‑designed molecules.
