Smarter, Faster, Better – The Next Frontier In Drug Delivery At the confluence of Moore’s law and Metcalfe’s law the next frontier in drug delivery becomes data-driven, personalised and outcome-based.
O
ver the past few decades, the cost of bringing new drugs to market has been doubling every nine years. This exponential trend, measured as the number of FDA approvals per billion USD spent on R&D, is known as the Moore’s law of the pharmaceutical industry and labelled Eroom’s law1 – Moore spelt backwards. Compounding this diminishing return on pharmaceutical R&D investments is the gap between clinical efficacy of medications as determined in a randomised controlled trial (RCT) setting and their real-world effectiveness.
Medication adherence is the key factor for the gap between RCT efficacy and real-world effectiveness as typically 50% of patients with chronic conditions fail to take the recommended therapeutic dose consistently, resulting in poor health outcomes and increased healthcare costs2. As a result, solely relying on the clinical efficacy of new medications
is not the solution to chronic disease management; rather, we need to find ways to help patients self-manage existing conditions. This also presents pharmaceutical companies with a $600 billion-plus opportunity, which is otherwise lost revenue due to medication nonadherence3. Moore’s law, attributed to cofounder of Intel Gordon Moore, has transformed computing through exponentially decreased costs and increased performance. There are already a number of examples across the healthcare industry where the impact of Moore’s law has resulted in exponential change, such as the cost of genome sequencing, adoption of DNA testing and utilisation of telehealth services4. As technology continues to get smaller, lighter, more efficient and intuitive, computers and sensors are also making their way into drug delivery devices. Today, connected injectable therapies

are still in their infancy when compared to respiratory and oral therapies. However, studies across these three therapeutic categories have consistently demonstrated that when drugs are augmented through sensors and connectivity, patient adherence and health outcomes improve. So could the application of Moore’s Law to drug delivery be the solution to medication non-adherence? Adherence is multifactorial and stems from the diversity of patient behaviours and barriers. Connected drug delivery devices, which measure dose-level (true) adherence in real-time, are the necessary first step towards a solution. However, improvements in adherence can only be realised when real-world data (RWD) from connected devices is applied effectively towards supporting patients with self-managing their condition outside the clinic setting.
