No new therapy without a clinical trial

Clinical trials

At present, no ground-breaking therapies exist for any form of EB. Although the current number of EB clinical trials being undertaken is still relatively small, the diversity of therapeutic approaches in preclinical development and entering clinical trials is growing rapidly.

In 2006, there was one pilot clinical trial for an ex vivo gene therapy in one patient – the first time there was proof that the underlying genetic fault in one type of EB could be corrected. Today, many different approaches to therapy are underway or planned, for all types of EB, including cell-, gene-, protein- RNA-based, and drug therapies.

2022 will go down as a milestone in the history of EB research. The first drug approved for EB was approved in the EU (Filsuvez®). The largest clinical trial worldwide involved over 50 clinical centers and more than 20 countries. The positive approval shows that the development of EB-specific drugs and therapies is possible and provides tailwind for further success.

There are two main types of clinical studies in EB research, interventional and observational studies. Both are important to move research forward and provide the best outcomes for people with EB. 

 

Interventional studies

Commonly referred to as clinical trials, interventional studies are prospective studies tailored to evaluate the direct impact of treatment or preventative measures in EB patients. This can involve a potential drug, medical device, activity, or procedure.

New potential drugs need to pass through three phases (1, 2, 3) of interventional testing to show that they are safe and effective before receiving approval from the U.S. Food and Drug Administration (FDA) or European Medicines Agency (EMA). After a drug is approved, further studies (phase 4) will be performed to monitor for safety and effectiveness.

Observational studies

Besides testing new therapy approaches for EB patients in clinical trials, observational studies, in which researchers observe participants and track health outcomes over time, are an important category of study designs, to address investigative questions. Well-designed observational cohort studies in EB are helpful in evaluating clinical and epidemiologic characteristics, phenotype-genotype correlations, natural history of the disease, molecular or cellular signatures, impact of treatment strategies and secondary outcomes of clinical studies. Further, basic science studies utilize hypothesis-driven experimental designs to improve the knowledge and understanding of underlying disease mechanisms in EB.

Future database for EB clinical trials

Currently EB Resnet members are preparing a database summarising all interventional and observational studies involving EB, registered on Clinicaltrials.gov and/or the EU Clinical Trials Register, and the UMIN Clinical Trials Registry.

In the 'Active clinical trials' table you will find those studies that are currently enrolling patients or, to our knowledge, will start/continue soon. It is planned to integrate tables listing registered studies of which the current status is unknown as well as completed/closed studies. As it is not always easy to keep track, please be aware that EB Resnet cannot guarantee the completeness of the lists, even if they are updated on a regular basis.

Clinical trials registers

There are several official clinical trial websites providing information on EB clinical trials worldwide. These include information about location, clinical lead, and trial sponsor, as well as the trial purpose, how the outcomes will be measured, and inclusion/exclusion criteria.
