Deep dives
The Risks and Rewards of Challenge Trials
Challenge trials involve intentionally exposing healthy volunteers to diseases, like malaria, to test the effectiveness of new treatments. This approach allows researchers to control the exposure environment, making it possible to conduct studies in regions where the disease is not endemic. By using a smaller group of participants and a safer testing setting, researchers can significantly reduce the costs associated with traditional field trials. For instance, while a tuberculosis vaccine trial can cost upward of $550 million, a challenge trial can be executed for about one to two million dollars, making it a more financially viable option for initial testing.
