“The drug development cycle takes 10 to 15 years and costs $2.6 billion per successful drug,” Liu explains. “Every year of delay costs companies nearly $2 billion, and 90% of clinical trials fail to meet enrollment timelines due to patient recruitment challenges.” These realities led to an important question: why does drug development still rely on manual processes and fragmented data when automation and AI could optimize nearly every stage?
Hill Research developed TheraGPT, a multi-agent AI platform designed to accelerate, automate, and optimize clinical trials. By leveraging AI, Hill Research aims to cut drug development timelines from over a decade to just four years, making treatments available to patients faster and at a lower cost. The company’s AI models streamline regulatory submissions, improve trial designs, automate compliance, and identify eligible patients more efficiently.
Liu recalls a striking example of how AI is reshaping the industry. In a breast cancer trial, Hill Research’s Patient Recruitment Agent scanned thousands of medical records in just four days, identifying 50 eligible participants—a stark contrast to the traditional manual screening process, which took two months to find only three. “This is the kind of impact AI can have,” Liu says. “It’s not just about efficiency; it’s about saving lives.”
Beyond patient recruitment, Hill Research’s AI also reduces human workload in clinical trials. “Trial staff spend nearly 50% of their time on repetitive tasks like data consolidation and compliance reporting,” Liu explains. “With AI, we’ve cut manual workload by 50%, allowing scientists and clinicians to focus on innovation rather than administrative tasks.”
The need for regulatory compliance has also been a major bottleneck in clinical trials. FDA submissions are time-consuming and prone to costly delays, often due to inconsistent data validation. Hill Research’s AI ensures real-time HIPAA and FDA compliance, streamlining the process and reducing regulatory pushbacks. “Every step of a trial, from recruitment to approval, can be optimized,” Liu emphasizes.
Liu credits a postdoctoral fellowship at Yale University for shaping an innovative approach to leadership and problem-solving. Under the mentorship of Timothy Gregoire, an AAAS Fellow in Biostatistics, Liu developed a deep understanding of how to challenge conventional methods in clinical research. Time spent in FDA Drug Data Safety Monitoring Board (DSMB) meetings provided firsthand exposure to regulatory bottlenecks, reinforcing the need for AI-powered compliance solutions. “That experience directly inspired the development of TheraGPT, which automates patient recruitment, compliance, and data analysis, reducing trial timelines from over a decade to just four years,” Liu says.
At the core of Hill Research’s approach is a human-centered philosophy. While AI enhances decision-making, it does not replace human expertise. The company ensures that clinicians remain involved in critical trial decisions, operating on a “human-in-the-loop” principle where AI works alongside medical professionals. “For example, our Data Analysis & Reporting Agent automates statistical analysis, but biostatisticians still oversee high-impact insights,” Liu explains. “We also embed bias reduction algorithms to ensure diverse patient recruitment and equitable access to treatment.”
AI has the potential to fundamentally change pharmaceutical development, and Hill Research is at the forefront of this transformation. “Decision-making in pharma is complex,” Liu says. “AI has no limitations on data processing, ensuring that every possible factor is considered in real time.” To avoid bias from a single AI model, the company employs a multi-agent LLM Model Tree, incorporating the latest advancements such as DeepSeek for biomedical applications and Hyper Graph Neural Networks (H-GNN) to continuously learn from clinical data.
Hill Research’s collaborations with major pharmaceutical companies demonstrate the tangible impact of AI in the industry. Working with Eli Lilly and Boston Pharmaceuticals, Hill Research’s TheraGPT was integrated into clinical trial pipelines, significantly reducing manual errors, improving protocol design, and accelerating data analysis. These improvements led to faster regulatory submissions and better-informed clinical decisions.
Gaining trust in the highly regulated pharmaceutical sector is no easy task, but Hill Research has taken a strategic approach. “We typically start with smaller pilot projects, proving the reliability of our AI, and then expand into larger-scale implementations,” Liu explains. This method has led to partnerships with top biotech firms and CROs, with a 90%+ client retention rate and 85% recurring revenue. The company also maintains strict compliance with HIPAA, GDPR, and FDA standards, reinforcing its credibility as an AI leader in clinical trials.
Looking ahead, Liu envisions a radical shift in drug development, comparing today’s pharmaceutical industry to pre-industrial-era craftsmanship. “Every drug today requires massive, customized efforts to develop,” Liu says. “But with AI, drug discovery will become a scalable, automated process, much like how Ford revolutionized car manufacturing.” In this future, AI-driven labs will generate medical knowledge at industrial speed, lowering the cost of drug development and making treatments more accessible.
To achieve this vision, Hill Research is focusing on expanding AI capabilities, regulatory integration, and market adoption. The company is actively developing predictive safety analytics, adaptive trial optimization, and AI-driven FDA submission tools, ensuring that AI seamlessly integrates into global drug development. “We are also working closely with regulators to shape AI-driven policies,” Liu adds.
A key success story highlights just how much AI can accelerate clinical trials. Working with Boston Pharmaceuticals, Hill Research deployed TheraGPT’s Data Analysis & Reporting Agent to address slow and error-prone data processing. The result? Manual programming errors were reduced by 85%, trial data reporting time was cut by 60%, and regulatory submission timelines improved by three months. “This is what AI can do,” Liu says. “It’s not just about making things faster—it’s about making better, safer drugs available to patients sooner.”
In the next five years, Hill Research aims to lead the AI-driven transformation of clinical trials. The company is targeting a $100 million revenue run rate, strengthening partnerships with global pharmaceutical companies, and expanding into Europe and Asia. “We believe the future of clinical research starts now,” Liu says. “By continuously innovating and aligning AI with regulatory and clinical needs, Hill Research is redefining pharmaceutical development—making life-saving treatments faster, safer, and more accessible worldwide.”
