Building the patient community.

There are many challenges in conducting rare disease research. The conditions are often poorly understood, small patient populations are dispersed around the world, and there are limited funding opportunities. Patient groups can serve as a key partner in overcoming these challenges, as they understand the impact of rare conditions on patients' lives. This gives patient groups valuable scientific insights into the disease. This can be used to create research strategies, address research bottlenecks and directly fund research that appropriately addresses patient needs. Patient groups can also play a critical role in recruiting and retaining patients for clinical trials, which reduces time and resource waste. By partnering with patient groups, research teams can improve efficiency of research and best meet the needs of patients. Researchers can also play an important role in building and supporting patient groups to unlock these benefits.

The patient's view on rare disease trial design - a qualitative study.

BACKGROUND: Clinical trials in rare diseases are more challenging than trials in frequent diseases. Small numbers of eligible trial participants, often complicated by heterogeneity among rare disease patients, hamper the design and conduct of a 'classical' Randomized Controlled Trial. Therefore, novel designs are developed by statisticians. However, it is important to be aware of possible design aspects that may jeopardize the feasibility of trial conduct. If the burden of participation is considered out of proportion by patients or parents, recruitment may fail or participants may drop out before trial completion. In order to maximize the chance of success of trials in small populations, it is important to know which aspects of trial design are considered important by patients. RESULTS: We have interviewed all ten members of the Patient Think Tank (PTT) of the ASTERIX project, a European research consortium on methodology for clinical trials in small populations. The PTT members are rare disease patient representatives who have completed extensive training in clinical trial methodology. We have analyzed the interviews qualitatively according to Grounded Theory using a thematic analysis, and we structured the topics in four chronologically ordered themes: 1. Involvement in trial design; 2. Opinions on trial design; 3. Trial participation; 4. Phase after the trial. Our main findings are that the PTT-members recommend that patients are involved in trial design from an early stage on, and have influence on the outcomes and measurement instruments that are chosen in the trial, the length of the study, the choice of participants, and the information that is sent to potential participants. Also, according to the PTT-members, patient groups should consider setting up disease registries, placebo groups should be minimized, and more education on clinical trials is advised. CONCLUSIONS: Rare disease patient representatives who have been educated about clinical trial methodology think it is important to involve patient representatives in research at an early stage. They can be of advice in trial design in such a way that the ratio of potential benefit and burden of trial participation as well as the chosen outcome measures and in- and exclusion criteria are optimized.
