HOW TO MAXIMISE THE VALUE CREATION OF SMART DEVICES
Healthcare is one of many industries being transformed by innovative digital products and services. Although healthcare may seem to lag behind others in unleashing the full potential of smart connected technologies, pharmaceutical companies and device manufacturers are vigorously pursuing joint R&D programmes to develop novel digital solutions. For example, with the ever-growing global diabetes pandemic, particular efforts are being made to lower the cognitive and emotional burden of insulin therapy with the help of smart devices and digital health platforms. Other therapeutic areas that require repeated self-administration will also benefit, such as hypercholesterolaemia, asthma or rheumatoid arthritis.
Although emerging trends toward outcome-based payment systems, real-time therapy monitoring and patient convenience are driving innovators to develop digital solutions that accelerate drug product market uptake, value propositions may remain vague for patients, healthcare professionals and payers. Tracking medication events and wirelessly transmitting such data to health platforms reflects a necessary, yet insufficient, condition to trigger behavioural change and in turn improve therapy outcomes. It is thus important to shed more light on the value proposition of smart devices for adherence monitoring in clinical trials. In fact, some of the most pronounced challenges investigators and participants are confronted with in large multi-centre trials relate to the absence of advanced adherence monitoring services.
CHALLENGES IN CLINICAL RESEARCH PRACTICE TODAY
Investigators face many obstacles that, in sum, reduce the motivation to participate in clinical research. These hurdles start with the recruitment of suitable patients but more significantly relate to the administrative burden of conducting and documenting clinical research. Due to busy patient practices, investigators typically devote little time to actual research. They need to complete large amounts of paperwork, prepare for regular audits and reviews, or are confronted with the ever increasing complexity of visit schedules and assessments. Efforts are made to understand whether patients’ routine administration of the investigational drug is in line with the study protocol.
“SmartPilot enables authentication of the combination product at the point-of-use. As such, it may alert users in case a batch of investigational drug has to be corrected or removed from the clinical trial…”
Current practices advise investigators and study personnel at each site to assess adherence using dosage counts or data patients have captured manually, which are then transferred to the source document after each visit. Phone calls are required to remind patients to take the investigational drug according to the injection schedule or clarify questions. There are also key challenges in tracking whether the correct presentation of the investigational drug was allocated to the assigned treatment arm and recorded in the source document accordingly. For instance, investigators have to detach part of the product label manually and affix it to the patient’s unique number in the corresponding source document before dispensing the packaging to the patient.
Similarly, patients value participation in clinical trials based on their perceived individual cost-benefit ratio. Despite today’s multi-centre set-up of clinical trials, travelling to the nearest study site may still take up significant time and impose costs. This is particularly relevant if such visits relate to simply monitoring health status, filling in questionnaires or performing dose administration. Furthermore, there is the latent risk of missing doses and hampering the validity of the study. In fact, patients are typically asked to record medication intake manually and inform about dose schedule adjustments or interruptions during the study. As such, the burden of extensive paperwork for patients is not limited to the informed consent process but continues throughout the trial.
Also, there is an overall trend to reduce the injection frequency of novel second-generation biological drugs. Although the added convenience compared with first generation medications is obvious, investigators are confronted with patients forgetting how to perform the procedure between injections. This may provoke handling errors, trigger additional interactions with trials centres and further diminish overall adherence.
“SmartPilot enables advanced adherence tracking services without requiring any physical modification to YpsoMate…”
CROs are similarly under pressure to reduce costs and optimise logistics for clinical trial monitoring. These activities target supplies strategy and planning, expiry management or return and destruction of investigational drug supplies. Most importantly, complexities also arise with trial site and patient management, such as patient enrolment and visits, treatment allocation, dosing and dispensing.
Currently there is no mechanism available targeting adherence data quality and integrity or data collection mechanisms. This is all the more surprising in that correct dose administration according to the study protocol is at the heart of assessing safety and efficacy endpoints for new investigational drugs.
SMART DEVICE REQUIREMENTS FOR ADHERENCE MONITORING SERVICES
Smart devices must feature certain sensing capabilities in order to be used as effective advanced adherence monitors. Let me illustrate these core requirements with SmartPilot for YpsoMate, a reusable add-on that transforms the proven and unchanged two-step auto-injector platform into a fully connected smart product system (Figure 1).
At its heart, SmartPilot contains a contactless sensor solution that differentiates between various states of the two-step auto-injector platform. In so doing, SmartPilot not only tracks whether an injection event has occurred according to the medication schedule but also whether that injection was successfully completed. Additionally, it can guide patients step-by-step through the injection process. Guidance includes direct visual and audible feedback on the SmartPilot add-on itself or the remote real-time display of the instructions for use on a companion mobile app.
SmartPilot adds another dimension to patient guidance: it identifies investigational drugs, tracks medication allocation to treatment arms, and thereby simplifies clinical trial supply monitoring. SmartPilot enables authentication of the combination product at the point-of-use. As such, it may alert users in case a batch of investigational drug has to be corrected or removed from the clinical trial.
Most importantly, SmartPilot enables advanced adherence tracking services without requiring any physical modification to YpsoMate. The same auto-injector configuration can be used flexibly with SmartPilot for clinical trials or without for commercial drug product.
SmartPilot sensing capabilities enable a number of value-adding adherence monitoring services during clinical trials. In doing so, SmartPilot sets the foundation for more patient-centric clinical trial design. Advanced notification and reminding services not only reduce the frequency of patient visits but also help to increase patient interest and enrolment in trials. Furthermore, automated adherence data tracking significantly reduces the administrative burden at clinical trial sites. For instance, certain sites may configure an automated alert if a patient repeatedly injects a partial dose only.
Table 1 summarises SmartPilot’s core functionalities as related to the various stakeholders’ value propositions.
The ability to monitor the progress of clinical trials in real-time is equally important to CROs and pharmaceutical sponsors. Remote trial monitoring dashboards may include insights into detailed patient adherence patterns. Innovative decision-making tools enable CROs to quickly respond to, and take appropriate measures against, emerging peculiarities in adherence patterns during clinical trials (Figure 2). For instance, CROs may think of device training and education seminars at certain clinical sites should handling errors accumulate over time.

Table 1: SmartPilot’s sensing capabilities translate into value-added services for key stakeholders in clinical trials.
The soaring costs in designing, implementing, and monitoring clinical trials point to a clear need for a fresh approach. New designs are required that minimise administrative tasks at trial sites and reduce the burden of participation on patients. Here, I described how such innovative, patient-centric trial designs can be enabled by advanced adherence tracking services, realised through smart devices. These services facilitate safe and effective self-administration of investigational drugs, enable complete remote patient monitoring and improve the quality and integrity of adherence data (Figure 3).
This article illustrates how the integration of smart devices in clinical research practice offers a unique value proposition and addresses some of the greatest challenges in performing large multi-centre clinical trials. It also disentangles what sensing capabilities a smart device must have in order to unleash its full potential as an effective clinical trial monitoring aid.
