Clinical trials 101.

Clinical trials provide valuable insight into how the human body responds to medical advancements, informing clinical researchers on new ways to prevent, detect, treat, or cure diseases. They offer hope for people in the present that we can find better treatments in the future.

Let’s break down what clinical trials are, why they’re important, and how 1nHealth fits in.

Clinical trials

Clinical trials are research studies that involve people. These trials are used by researchers and medical professionals to evaluate the results of introducing participants to a certain medical, behavioral, or surgical intervention.


Clinical trials are how researchers test the safety and efficacy of new treatments before they go to market. Researchers spend years working with different groups of people and the treatment making sure that no stone is left unturned. An administration that handles approval of medications and therapies is operating alongside the trial through the entire process.


Before a governing board (such as the FDA in the US) can approve a trial to start, many lab tests and studies are done to test the safety and effectiveness of the trial. That is when the 4 stages of trials can start.

Phase 1

The first phase after the approval for trials focuses mainly on safety. Researchers use new treatment on small group of healthy adults to look for any possible side effects.

Focus on safety

Phase 2

The second phase has a larger number of participants and focuses on the effectiveness of the medication, device, or behavioral intervention for the population it was designed for.

Check effectiveness

Phase 3

The largest and most diverse group of volunteers participate in this phase to check the treatment in different populations of people and, if needed, possible dosage before government board approval.

Effectiveness across populations

Phase 4

This is the stage of trials that occurs after the government board approval, where the efficacy and safety are continuously monitored in diverse and large populations of people in the market over a longer period of time.

Long-term efficacy & safety

Why participate?

Whether you’re in good health and want to help move science forward, or you’re looking to try the newest treatment for an illness—participating in clinical trials comes with a lot of benefits for you and the rest of the world, including:

  • Access to new treatment methods
  • Help further scientific knowledge
  • Occasional compensation for participation
  • Take an active role in the world of health care
