A clinical trial is a medical study focused on new therapies, vaccines, or new ways of using known treatments. Clinical trials (also called research studies) determine if new drugs or medical devices are safe and effective.
All clinical trials have guidelines for who can and cannot participate. Criteria are based on age, gender, disease stage, previous treatment history, and more. Some studies seek participants with specific illnesses or conditions that need to be studied in a clinical trial, while others only need healthy participants.
Every trial has different patient activities (things patients do or complete as part of the trial). In our trials, these often include attending study appointments, tracking symptoms, taking study medication, or using study a study device, and providing information to evaluate the effectiveness of the product being investigated. Clinical trial teams including doctors, research staff, and other health care professionals, check participants' health, give specific instructions, monitor participants, and follow up after the trial. Some trials involve more tests and visits than others – all trials feature a dedicated research team.
