Depression is a widespread and often severe condition that affects millions globally. While there are effective treatments available, such as psychotherapy and medication, finding the right combination for each patient can take time. Now, researchers at six European medical centers, led by Charité – Universitätsmedizin Berlin, are launching a groundbreaking project to accelerate the development of more effective depression treatments. With more than €13 million (£11.7m) in funding from Wellcome, the PEARLDIVER project aims to find quicker solutions for individuals suffering from this debilitating condition.
Current clinical trials form the backbone of evidence-based medicine. However, many trials fail to provide conclusive results for practical use in treating patients. Often, available treatments only work for a subset of individuals, and the approval of new mental health medications lags behind other fields like oncology or neurology.
Professor Christian Otte, Director of Psychiatry and Neurosciences at Charité and the project’s medical lead, explains: “For patients who don’t respond to initial treatments, there is a critical need for effective, evidence-based therapies. This platform study will allow us to accelerate both the development of new treatments and identify which existing therapies may be the most beneficial for specific patients.”
To fast-track breakthroughs in depression treatment, the researchers are using an innovative study design called a platform study. Unlike traditional clinical trials, where each treatment is tested in isolation, a platform study uses a shared infrastructure and a common control group to evaluate multiple treatments simultaneously. This not only speeds up the research process but also ensures that the results are more meaningful and comparable.
Professor Stefan Gold, Scientific Director of the PEARLDIVER project, compares the traditional trial setup to building a new stadium for each football match. “In PEARLDIVER, we’re building one large stadium, and all the researchers can use it for multiple studies. This approach dramatically reduces time and resources while ensuring that each study is more reliable.”
The four-year project will create a Europe-wide research infrastructure that will enable comparisons of treatments and control groups to evaluate both new and existing treatments. The first year will focus on building the platform, followed by trials assessing the safety and efficacy of two new medications for depression, with plans to expand the project over time. Participant enrollment is expected to begin in 2026.
What sets the PEARLDIVER project apart is its inclusion of patients in the research process. Not only are patients participating in the trials, but they have also played a crucial role in designing the study. Fanni-Laura Mäntylä, a patient representative, says, “We aim to improve how clinical trials for mental health are designed and run, ensuring that treatments evolve to better help people facing mental health challenges.” The European Patients’ Forum (EPF) is supporting the project to ensure patient-centered outcomes.
With multiple treatments being tested at once and a reusable infrastructure, the platform study approach is highly efficient and less burdensome for participants. It also speeds up regulatory approvals, allowing for quicker insights and faster elimination of ineffective treatments.
Dr. Kim Donoghue, Senior Research Manager at Wellcome, adds: “This innovative platform study will streamline the testing of new depression treatments, helping researchers identify which therapies work best and for whom. It’s an exciting step forward in mental health research.”
The PEARLDIVER project represents a major step forward in the search for better, faster treatments for depression. By building a shared infrastructure for clinical trials, researchers hope to accelerate the development of new therapies and find the right treatments for patients more efficiently. With patients directly involved in the process, this project aims to transform depression treatment and improve outcomes for people across Europe.
