Studying MS Treatments

Differences Between Real World Evidence and Clinical Trials

After clinical studies test the safety and effectiveness of drugs and vaccines, there is still a need to monitor the use of the drug or vaccine in the real world.

Because clinical studies are conducted under strict patient selection criteria, the criteria do not always reflect the variety of patients who are prescribed the drug in real the real world.

The term for monitoring the use of a drug after it has been approved is postmarketing surveillance

Increasingly, real-world evidence is being used by healthcare professionals and regulatory bodies to find additional side effects and safety. Side effects that occur very rarely (i.e., 1 in every 10,000 or more doses) require large numbers of people to take the drug. That’s where real-world studies come in.

The collection and analysis of data from everyday patients is called real-world evidence

Real-world studies in MS have looked at the effectiveness and side effects of various DMTs and patient populations.

Studies involving long-term use of DMTs in the real world can help doctors and patients make informed decisions about their choice of treatment now and down the road.
