Why this research matters
Close relatives of people with rheumatoid arthritis have a high risk of also developing the disease. Several drugs are being tested in clinical trials to see if they can prevent this from happening. A 2019 study shed new light on what would make the best treatment from the consumer perspective, which can now shape how trials are designed and care is delivered.
What is this research about?
Rheumatoid arthritis (RA) is the most common form of inflammatory arthritis, which can cause significant pain and disability. First-degree relatives (i.e., parents, siblings, or children) of people with RA have a higher risk of also getting the disease. Some drugs usually used to treat RA are being studied in clinical trials as prevention treatments for this high-risk group. However, most trials focus on how much the risk is lowered, without considering what other factors influence a consumer’s choice to take a preventive drug.
What did the researchers do?
Dr. Mark Harrison and his team presented over 280 first-degree relatives of people with RA with hypothetical scenarios where they could choose between two preventive drugs with different attributes, or no treatment at all. The researchers analyzed what trade-offs the participants considered when making their choice.
What did they find?
Participants valued many treatment attributes beyond a drug’s ability to reduce RA risk. Other important considerations included whether it was easy to take the drug (e.g., daily pills), whether it was recommended by a healthcare professional, and whether there were risks of serious side effects. Participants were often willing to sacrifice the level of risk reduction to accommodate other preferences. Overall, predicted uptake was high for non-biologic drugs (particularly those given as pills) but low for biologics.
What is the impact of this research?
This research shows that for people at high risk of developing RA, the decision to take a preventive drug can be complicated. It’s not as simple as whether the drug decreases RA risk – many other factors come into play.
These findings suggest that the consumer perspective needs to be integrated into the planning and design of clinical trials on potential preventive treatments to make sure that consumers and researchers alike will get the answers they need. This study also highlighted the importance of a healthcare professional’s recommendation, supporting a need for educational tools to help patients and doctors make treatment decisions together.
This project highlighted the complexity of decisions that people are making when they decide to take treatments or not. If we don’t take the time to understand what is important to people, then too often we might be researching treatments that people will not want to take. This explains why sometimes treatments, even if shown to be beneficial in trials, won’t improve outcomes for people. In this work, our results suggest that biologics are unlikely to be a sought-after preventive treatment for RA "
