Organ-on-a-chip: Thumb-sized Organs, Huge Potential For Pharma R&D

Thumb-sized devices that mimic human organs could change the way we make drugs—and benefit countless patients. Discover what impact organ-on-a-chip could have on drug development and how Pharma stakeholders are investing to realise its true potential.

 

 

11 years. It’s the average time it takes for a therapeutic to make its journey from the laboratory to our medicine cabinet. 11 years of thorough research, during which sponsors spend a significant amount of time and resources evaluating a drug candidate’s safety and efficacy. 

Most common methods used by drug developers rely on animal and cell-based models that approximate the human biology, to ultimately predict if a therapeutic is safe and effective for humans. However, while these approaches provide highly valuable insights for drug developers, it is important to recognize they also come with certain drawbacks. 

As 90% of drug candidates that enter clinical trials fail due to a lack of efficacy or unexpected safety issues, and with a cost of failed attempts to bring a single drug to market reaching € 1.5Bn—Pharma is urged to find models that better reflect the human biology. 

 

 

Holding the potential to mimic human physiology more accurately than existing models, OoC could enable more realistic and precise drug testing, reduce R&D costs and timescales to bring new therapeutics to the clinic—all while scaling back on animal testing. 

With such promising prospects, the technology keeps gaining momentum—as the whole pharma ecosystem pushes to overcome the remaining challenges and unlock its full potential. 

 

What is an Organ-on-a-chip?

Originating in the early 2010s with the development of the first human lung-on-a-chip, the concept of organ-on-a-chip (OoC) emerged as a response to the well-known limitations of cell and animal-based testing methods. Recognizing this gap, researchers sought a solution that could bring more accuracy and scalability all while reducing reliance on animals. 

 

Various models are used for pre-clinical research

 

Combining biology and microtechnology, organ-on-chips are micro-scale 3D systems that replicate human physiology. Using microfluidics and cells, these systems emulate physiological and mechanical conditions experienced within the human body.  

In vitro, miniature tissues—engineered or natural—are cultivated within intricately designed microfluidic chips. The latter finely control cell microenvironments, sustaining tissue-specific functions, striving for a more faithful replication of human physiology.

OoC applications: highly transformative perspectives for Pharma R&D

13 years—and many advances in organ-on-a-chip engineering later—the possibility of seeing OoC applied to advance biomedical research and healthcare seems closer than ever. 

From pinpointing potential drug targets and conducting sophisticated toxicity assessments, to unravelling the intricacies of drug efficacy and enabling personalized medicine breakthroughs, the applications below showcase how much OoC could impact Pharma R&D operations in the future.

 

Target Discovery 

With its ability to model the human system, OoC could precisely identify drug targets in a controllable and traceable manner. This platform proves particularly powerful in dissecting the intricate processes and mechanisms underlying cancer progression, including cell migration and invasion, extracellular signalling, biophysical factors within the tumour microenvironment. 

 

Toxicology and Safety Assessments

The technology might become instrumental in toxicity and safety assessments of drugs and other compounds. By simulating the organ's microstructure and function, organ-on-a-chip devices provide a more accurate representation of how substances interact with human tissues, enabling early detection of potential toxic effects and improving the safety profile of pharmaceuticals.

 

Efficacy Studies

Organ-on-a-chip platforms have the potential to assess drug efficacy in a more realistic environment. Researchers can observe how a drug interacts with specific organs, replicating the complex conditions of the human body. This approach enhances the understanding of a drug's effectiveness before progressing to more resource-intensive and time-consuming clinical trials.

 

Absorption, Distribution, Metabolism, and Excretion (ADME) Studies

Organ-on-a-chip technology is utilized for studying the pharmacokinetics of drugs—how they are absorbed, distributed, metabolized, and excreted by the body. This information is critical in determining a drug's bioavailability and potential side effects, contributing to more informed decisions during the drug development process.

 

Personalized Medicine

Organ-on-a-chip technology has the potential to address personalized medicine by allowing researchers to create models that mimic the unique characteristics of an individual's organs. This enables the testing of drugs in a more patient-specific context, considering factors such as genetic variability and individual responses to treatment—ultimately paving the way for more tailored and effective therapeutic approaches.

Fostering the development and utilization of organ-on-chips 

With the promise of enabling more realistic and precise drug testing, reducing R&D costs and timescales to bring new therapeutics to the clinic—all while scaling back on animal testing—OoCs are definitely gaining momentum. 

The devices’ potential for drug testing, personalized medicine and disease modelling has captured attention from major industry players—triggering a series of initiatives. 

From research and strategic partnerships to fundings, pilot projects or consortiums. In the course of 5 years, major Big Pharma companies, Contract Services Providers, investors and organ-on-a-chip companies have undertaken collaborative efforts to accelerate the development and utilization of OoCs. 

The list of recent initiatives below—picked from the data collected via our BI platform—is by no means exhaustive. However, it highlights Pharma’s willingness to embrace and develop OoCs—and demonstrates how the technology can actually be embedded into existing R&D workflows across many drug modalities.

Current Challenges and Future Perspectives for OoC 

The collaborative efforts and investments mentioned above have strongly backed the growth of the organ-on-a-chip market—accelerating the technology’s shift from theory to its actual utilization in labs. 

Yet, despite major advancements and an increasing acceptance among the Pharma ecosystem, key challenges remain to be solved before considering OoCs implementation on a large scale. 

 

4 key barriers on the path to widespread adoption 

Standardization: Achieving uniformity and standardization across various Organ-on-a-Chip (OoC) models poses a significant challenge. The diversity in designs and protocols hinders the comparability and reproducibility of results.

Complexity: Developing OoCs that accurately replicate the complexity of human organs is challenging. Mimicking the intricate physiological and mechanical aspects of organs in a microscale environment requires advanced engineering and biological understanding.

Validation: Ensuring that OoCs reliably replicate the physiology of human organs is crucial for their widespread adoption. Rigorous validation processes are needed to establish the accuracy and reliability of OoC models in predicting human responses.

Cost: The initial setup and maintenance costs of OoC technology can be high. Achieving cost-effectiveness while maintaining the sophistication of the technology remains a challenge, particularly for widespread implementation.

 

Riding a wave of regulatory support towards future 

As paramount tackling those challenges may be to unlock OoC’s full potential, a recent regulatory milestone might turn out to be a powerful catalyst for addressing them. 

The FDA Modernization Act 2.0, signed into law by President Biden in December 2022, marked a transformative shift, as it aims to reduce the dependence on animal models for drug discovery. The legislation promotes researchers to use animal alternatives—such as OoCs and other microphysiological systems (MPS)—when submitting Investigational New Drug (IND) filings to the FDA. 

Riding this wave of regulatory support, the future could hold even brighter perspectives for organ-on-a-chip, as it will encourage further progress within the field:
