At Sinkove, we're developing a radiology digital twin that leverages AI—specifically denoising diffusion models—to create synthetic control arm data for clinical trials, significantly reducing the cost, time, and ethical concerns associated with traditional patient recruitment.
What Are In-Silico Clinical Trials in Radiology?
In-silico clinical trials represent a paradigm shift in how medical research is conducted. These trials use computer simulations and virtual patients to test imaging technologies or treatments entirely on computers, without physical patient participation. In radiology specifically, these virtual trials leverage digital patient models, physics-based simulations, and predictive algorithms to evaluate the safety and efficacy of radiological devices and techniques.
Traditional clinical trials in radiology face significant challenges: they're expensive (costing $6,500-$10,000 per control arm patient), time-consuming, and raise ethical concerns about exposing patients to placebos or suboptimal treatments. In-silico approaches offer a faster, cost-effective alternative while addressing these ethical constraints.

Regulatory Trends: Growing Acceptance
The regulatory landscape for in-silico trials is rapidly evolving, with several significant developments:
• FDA Affirmation: In 2024, the FDA confirmed that computational models represent a viable source of regulatory evidence for imaging device evaluation, marking a significant milestone for the industry.
• VICTRE Project Success: The FDA's Virtual Imaging Clinical Trials for Regulatory Evaluation (VICTRE) project successfully demonstrated that fully simulated trials could replicate the outcomes of physical trials for breast imaging devices, building confidence in simulation-based approaches.
• Standardization Efforts: Development of Good Simulation Practice guidelines and the FDA's framework for Medical Device Development Tools are establishing credibility and standards to ensure virtual trials are reliable and reproducible.
• International Recognition: The first International Summit on Virtual Imaging Trials in Medicine (April 2024) attracted over 130 stakeholders including regulators, clinicians, and industry representatives, highlighting the growing momentum behind in-silico approaches.
These regulatory developments are crucial for market adoption, as they provide the framework and confidence needed for companies to invest in virtual trial technologies with assurance that the results will be accepted by regulatory bodies.
Key Players: How Sinkove Compares
The in-silico trials landscape features various companies with different approaches and specializations. Here's how Sinkove compares to other notable players:
Company | Core Technology | Focus Area | Key Differentiator |
---|---|---|---|
Sinkove | Diffusion models for synthetic radiology data | Imaging-based clinical trial control arms | Specialized in high-fidelity radiological digital twins with proven successes with Pfizer and Bayer |
Novadiscovery | Disease modeling platform (Jinkō) | Drug development, trial outcome prediction | Established modeling & simulation as a service approach |
InSilicoTrials | Web-based simulation marketplace | Multi-domain medical device testing | Democratizing access to simulation tools |
Insilico Medicine | Deep learning for drug discovery | AI-driven drug candidate generation | End-to-end AI drug discovery with clinical validation |
GNS Healthcare | Causal AI (REFS platform) | Disease progression and treatment outcome | Focus on precision medicine and patient stratification |
Sinkove stands out in this landscape through our specialized focus on radiological imaging and our use of cutting-edge diffusion models. While many companies offer general simulation capabilities or drug-focused platforms, Sinkove's radiology digital twins specifically address the unique challenges of imaging-intensive clinical trials.
Our early successes with pharmaceutical leaders demonstrate the practical value of our approach. With Pfizer, we've shown that our AI digital twins improve understanding of treatment effect by simulating different imaging scenarios. Our work with Bayer's AI innovation platform delivering synthetic training data has further validated the power of our technology.
The Future: Where In-Silico Trials Are Headed
The field of in-silico trials in radiology is rapidly evolving, with several transformative developments on the horizon:
• Hybrid Trials: The future likely holds "hybrid" clinical trials that combine traditional and in-silico approaches—perhaps using virtual patients for initial screening or control groups while maintaining traditional arms for intervention groups. This balanced approach leverages the strengths of both methodologies.
• Advanced AI Integration: As AI models continue to improve, especially in generative capabilities, in-silico trials will produce increasingly realistic and clinically relevant results. Future systems will integrate multiple data types (imaging, genomics, clinical records) to create more comprehensive digital twins.
• Personalized Medicine: In-silico trials will advance personalized medicine by enabling "N-of-1" virtual trials where individual patient data drives simulations to predict personal treatment responses before actual treatment begins.
• Regulatory Evolution: Regulatory frameworks will continue to mature, likely establishing clear pathways for in-silico evidence in device and drug approvals. We anticipate the development of specific validation criteria and standards for simulation-based submissions.
Conclusion: Sinkove's Vision
At Sinkove, we believe in-silico clinical trials represent the future of radiology research. By creating AI-powered digital twins that generate synthetic control arm data, we're addressing the fundamental challenges of traditional trials: high costs, lengthy timelines, and ethical concerns.
Our vision extends beyond simply replacing control arms. We see a future where entire trial simulations can be run in silico before physical implementation, allowing researchers to optimize protocols, predict outcomes, and identify potential issues in advance. This approach will not only accelerate innovation but also improve patient safety by reducing unnecessary exposure to experimental treatments or radiation.
The aerospace industry doesn't crash planes to test new wing designs—they simulate them. Similarly, Sinkove is enabling the healthcare industry to reduce patient risk and accelerate innovation through advanced simulation. By harnessing the power of AI and radiology, we're creating a future where clinical trials are faster, safer, and more effective—ultimately bringing better treatments to patients sooner.
