Clinical trial phases
See how different phases answer different questions.
Phase I to IV
Phase I focuses on safety, Phase II on activity, Phase III on comparison, and Phase IV on long-term learning.
Why do people participate?
People join studies for different and personal reasons.
Benefits and risks
Understand the balance between possible benefits and uncertainty.
No guarantees
Trials may offer access to new options, but they can also involve side effects, extra visits, and uncertainty.

What are clinical trials?
Clinical trials are research studies that help doctors understand how new treatments, tests, or approaches work in people.
Clinical trial phases
Clinical trials are often divided into phases, and each phase has a different purpose.
Phase I
Usually focuses on safety, side effects, and the best dose to study.
Phase II
Looks more closely at how well the treatment works for a specific condition.
Phase III
Often compares the new treatment to standard care in a larger group of people.
Phase IV
Continues learning after approval, including long-term effects and real-world use.
Why do people participate?
People choose to participate in clinical trials for different reasons, and those reasons can be deeply personal.
Benefits and risks
Clinical trials may offer potential benefits, but they also involve uncertainty and possible downsides.
Potential benefits
Access to new therapies, close monitoring by a care team, and the chance to contribute to future treatment advances.
Possible risks
Side effects, extra visits or procedures, unexpected burdens, and uncertainty about whether the treatment will help.
Informed consent
Before joining a clinical trial, patients go through a process called informed consent.
Your rights as a patient
Patients do not lose control when they join a study. Rights still matter, and they matter throughout participation.
Voluntary participation
You have the right to decide whether you want to join.
Questions anytime
You can continue asking questions before, during, and after enrollment.
Right to leave
You can choose to stop participating at any point.
Privacy matters
Your personal and medical information should be handled with care and according to study rules.
Costs and insurance
Costs in clinical trials can vary depending on the study, the type of care involved, and the patient’s insurance.
Common myths
Many people hear things about clinical trials that sound frightening or misleading. A few common myths deserve a clearer explanation.
Myth: “I will be treated like a guinea pig.”
Reality: trials follow strict safety, ethical, and scientific standards.
Myth: “I cannot leave once I join.”
Reality: participation is voluntary, and patients can choose to leave.
Myth: “Clinical trials are only a last option.”
Reality: some trials are available earlier in care, depending on the condition and study design.
Myth: “My doctor will stop caring for me.”
Reality: care teams remain involved, and communication still matters.
What happens during a trial?
Each study is different, but many trials follow a similar structure from the first evaluation to the final follow-up.
Screening
Tests and assessments help determine whether the study may be a fit.
Eligibility review
The study team checks whether the patient meets the study criteria.
Informed consent
The patient reviews the study information and decides whether to participate.
Study participation
This may include visits, treatment, laboratory tests, imaging, questionnaires, or monitoring.
Follow-up
Some studies continue checking outcomes or safety after active participation ends.
Questions to ask your doctor
Good questions can help patients and families feel more confident during discussions about research participation.
Is this study appropriate for my condition?
What is the goal of the study?
What are the possible risks and benefits?
What extra visits or tests are required?
What costs might be involved?
What happens if I want to leave the study?
Family and caregiver support
Clinical trial participation can affect more than one person. Family members and caregivers often help patients stay organized and supported.
Common questions from patients and caregivers
Some questions come up again and again. These are a few of the most common ones.
The goal is not to rush a decision.
The goal is to help patients and families feel informed, supported, and more confident when talking with their care team about clinical trials.
