Once a week, Gertrude takes a photo of her forearms with her smartphone. She then sends that photo via an app to the doctor, the principal investigator. The doctor is researching and investigating how genetics affect the development of atopic eczema. Gertrude has atopic eczema, and, alongside more than 3,000 patients in Denmark and the US, she is participating in a so-called virtual decentralized clinical trial. Gertrude is a fictional character; the trial however is real and conducted by Bispebjerg Hospital in Copenhagen, Denmark and Stanford Health Care in collaboration with Studies&Me, a virtual contractual research organization.
Everything in the trial is conducted digitally, which makes it easy and less complicated for the patients to participate, as they do not have to go to the hospital for a check-up, which is the case with a traditional clinical trial. Instead, they can participate from their living room via their smartphones. In the beginning of the trial, the participants receive a DNA kit by mail, in which they submit a saliva sample that is brought in for an analysis. Each week the patients submit a photo of their eczema and answer a survey. Furthermore, passive data such as geographical location, daily level of activity and sleep pattern is also collected from the participants. This information is important to the principal investigators when assessing which factors determine the flare up of the eczema.
An area in rapid development
In Denmark, Europe and especially in the US, clinical research is in rapid development, and an increasing number of clinical trials are digitalized and decentralized. According to GlobalData, it is expected that 1,300 clinical trials with decentral or virtual elements will launch in 2022. That is an increase of 28 percent compared to 2021. This development has been underway for more than a decade, yet it accelerated during the COVID-19 pandemic. Due to the risk of being infected and the enormous pressure on the healthcare system, many of the trials were put on hold in the beginning of the pandemic. They have since been resumed and are conducted digitally and decentralized in the home of the patients.
The participants will typically get the trial medication sent by mail or retrieved by a nurse, who will visit them at home. During the trial, they have ongoing phone or video calls with the principal investigator instead of going for a check-up in person. In addition, wearables or other medical equipment will typically collect electronic data about the patient. The clinic responsible for the trial will then receive the data from the devices digitally. For many patients the decentralized model makes it easier to participate in clinical trials. Mobility and the physical distance to the hospitals are no longer barriers, and at the same time, it lifts the patient’s burden and hassle of going to a hospital for trials.
It is self-evident that not all clinical trials can be conducted in a decentralized manner. The experience in the US is, however, that most of these trials can be, and that even more can be conducted in a hybrid format, where parts of the trial are conducted in the home of the patient, while the rest takes place at the hospital.
