What is a clinical trial?
• Clinical trials look at new ways to prevent, detect, control or treat disease.
• The GOAL is to find if a new test or therapy is safe and effective.
• It is important to have many types of people with different ages, races, ethnicities, and genders to see how different people respond to a treatment
http://www.nih.gov/health/clinicaltrials/basics.htm
What is a clinical trial?
• Participants are assigned to receive one or more interventions (or no intervention)
• Researchers evaluate the effects of the interventions on biomedical or health-related outcomes.
• The assignments are determined by the study protocol.
• Participants may receive a drug, treatment, procedure, or other types of interventions.

Clinical Research Categories
• Interventional
• Observational
• Ancillary
• Correlative
Interventional
• Individuals are assigned to receive intervention
• Drug, Device or Other (ie behavioral)• Diagnostic, Therapeutic, Supportive Care• Assignment may or may not be random• Participants are followed and a health
outcome is assessed
Observational
• Involves no intervention or alteration of the status of the participant
• Biomedical or health outcomes are assessed in a pre-defined group of participants
• Participants may or may not receive the intervention
• The investigator is not responsible for assigning the specific intervention
Observational Studies vs. RCTs
Armstrong, K, JCO 2012;30: 4208-42144
Strengths Observational Studies
• Examine “real world” populations– Diversity increases generalizability
• Large numbers of participants• Leverage existing data• Includes vulnerable populations• Power to find a dose response relationship• Can be completed more quickly with less
cost
Limitations of Observational Data
• Selection Bias• Systematic error in the ascertainment of study subjects
• Intervention groups differ in characteristics that are associated with the outcome of interest
• Performance Bias• The delivery of one type of intervention is associated with
generally higher levels quality of care
• Detection Bias• Outcomes of interest are more easily detected in one
group than another
Ancillary/Correlative
• Ancillary– Stimulated by a main clinical trial to answer
secondary question– Includes patients accrued to the main study
• Correlative– Laboratory based– Use specimens that exist– Used to assess risk, outcomes, response
What are the types of clinical trials?
Diagnostic: Protocols designed to evaluate interventions aimed at identifying a disease or health condition
Prevention: Protocols designed to assess interventions aimed at preventing the development of a disease or health condition
Screening: Protocol designed to examine methods for identifying a condition or risk of a condition in people not known to have the condition
http://www.nih.gov/health/clinicaltrials/basics.htm
What are the types of clinical trials?
Treatment: Protocol designed to evaluate interventions for treating a disease
Supportive Care: Protocol designed to evaluate interventions to maximize comfort, minimize side effects or prevent the decline in a health condition
Health Care Deliver: Protocol designed to evaluate the delivery, processes, management, organization or financing of healthcare
http://www.nih.gov/health/clinicaltrials/basics.htm
Clinical trial stages
Pre-clinical stage
• A new drug or treatment is tested using animals to determine if it is safe for humans
Phase I
A new treatment is tested in a small number of people to see how safe it is
and what are its side effects
Involves 20-80 subjects
Phase II
A treatment is given to a larger number of people to see its effectiveness and safety
Involves 100-300 people
Phase III
A treatment is tested in large number of people to prove that it is effective, check
side effects, compare it to other treatments and get safety information
Involves 1,000-3,000 people
Phase IV
A treatment is now approved by the FDA and available to the public but its usage,
risks and benefits are still monitored
What is a clinical protocol?
• Studies are led by investigators who write the study protocol
• Protocols describe: – Who can participate – The length of the study– What they will receive – What information is collected
http://www.nih.gov/health/clinicaltrials/basics.htm
What is a clinical protocol?
Eligibility criteria are an important part of the protocol
• Criteria often include: – Age – Gender Often not everyone– Type of disease meets criteria for– Stage of disease participation– Previous treatment– Medical conditions
http://www.nih.gov/health/clinicaltrials/basics.htm
How does a clinical protocol become approved?
• Once an idea is formulated and the protocol written it must be reviewed
• All clinical trials in the US are approved and monitored by an Institutional Review Board (IRB)
http://www.nih.gov/health/clinicaltrials/basics.htm
What is an IRB?
An IRB is an independent committee of doctors, statisticians, and community members who review a study’s safety,
human rights, and ethics
Informed consent
Informed consent • Understanding the procedures involved,
risks and benefits of a study are extremely important when making decisions
• The informed consent document and discussion are used to help you in this process
• Translation and interpretive services are available during this time
http://www.nih.gov/health/clinicaltrials/basics.htm
Clinical trial concepts• Placebo: Inactive product that is very similar to
the real drug or treatment but does has no affect on the condition
• Randomization: A person is randomly assigned to one of any treatments in a study. Done to avoid bias or influence on the outcome
• Single or double blinding: the subject doesn’t know the treatment (single) the subject and researcher do not know the treatment (double)
http://www.nih.gov/health/clinicaltrials/basics.htm
What happens once the clinical trial is over?
• Analysis: All collected information is analyzed to see if there are any differences between treatment groups
• Peer review: Experts review the analysis to see it is sound
• Publication: Once it is past peer review it is published in a scientific journal
http://www.nih.gov/health/clinicaltrials/basics.htm
Why should I take part in a clinical trial?
1. Access to a new intervention that’s not normally available.2. A new intervention may improve your health.3. Most studies cover the cost of the intervention.4. You are helping researchers answer questions about a disease.5. You play an active role in your own health care.
1. A new intervention may not be better than the standard.2. A new intervention has risks and side effects.3. Your health insurance may not cover all costs.4. If you are in a randomized study you will not be able to choose the intervention you receive.5. You may need to make more visits to the clinic or hospital.
NCI Clinical Trials
• NCTN – National Clinical Trials Network
• NCORP -NCI Community Oncology Research Program
NCI Supports Community-Based Cancer Research
• Majority of cancer care is provided in the community
• Access to large diverse patient populations
• Access to real world healthcare delivery settings
• Test feasibility of new interventions/processes
• Engage community oncologists in the research process to accelerate the uptake of evidence-based practice

How do I find out about trials?
• ONCOLOGISTS– ASK YOUR ONCOLOGIST - They are familiar with
clinical trials resources, websites, and contacts
• COMMUNITY RESOURCES– Local support groups– American Cancer Society
• INTERNET– All trials are registered in the US and worldwide on
clinicaltrials.gov
• FRIENDS & FAMILY
