Frequently Asked Questions About Clinical Trials

What is a Clinical Trial? How do I join a Clinical Trial? 

Choosing to participate in clinical trials is a big decision, so we want to make sure you’re completely informed. Find out what a clinical trial is and what you can expect when volunteering to participate by browsing the questions below.

What is a clinical trial?

Clinical research trials are supervised research studies of medical procedures or medications to evaluate their safety and effectiveness. Each clinical study is designed to answer specific scientific questions and to find new and better ways to help patients. For any given disease or condition, a clinical trial may:

• Establish the first effective treatment
• Establish a more effective treatment
• Establish a better tolerated treatment
• Find a new use for a currently available treatment

How are new drugs approved?

Before a medication can be prescribed, it must undergo an extensive testing and approval process. First, the investigational medication goes through rigorous preclinical testing. If it is permitted by regulatory agencies for the next phase of drug development, the investigational medication is then tested for safety in humans through clinical research studies. If endorsed by regulatory agencies after that, the investigational medication is further tested for both safety and effectiveness in patients with the disease or disorder it is intended to treat. The sponsor then submits a report (New Drug Application) to the appropriate regulatory authority, who either approves it, rejects it, or requires more testing.

What if I change my mind?

That’s no problem. Our medical trials are voluntary, so if you have a change of heart after you've applied, at the screening session or even during the clinical trial you are free to withdraw your consent. If you’ve already started the clinical trial our doctors may want you to come back for a visit, just to check that the drug is out of your system.

How are the rights and welfare of a study participant protected?

Clinical research studies are conducted by qualified medical staff and physicians. Additionally, various worldwide agencies have regulations to protect clinical research participants and standards for how studies are conducted. For example, an independent ethics board reviews each study protocol and associated materials. This review is conducted to make sure the study is scientifically and ethically sound. The independent ethics board oversees the processes that the clinic uses for informing you about clinical research studies, including why the study is being done, what will happen during the study, risks involved and previous study results that may impact an individual’s willingness to participate.

Thanks for your feedback

Will my information be kept confidential?

Your privacy will be respected by Medical Research Group of Central Florida staff and no information will be given out about your participation and/or your medical information unless required by law. For example, the Sponsor and its representatives, applicable regulatory agencies such as the US Food and Drug Administration, and the authorized independent ethics board may inspect your clinical research study medical records, which may include your name, address and other personal information that identifies you. If necessary, some or all of your records may be copied during these inspections.
The results of the clinical research study may be presented at meetings or in publications. However, you will not be personally identified in any presentations or publications.

Thanks for your feedback

Where can I find independent information?

There are a number of online resources you can use. We have included a list of a few to get you started below: is a registry of federally and privately supported clinical trials conducted in the United States and around the world. provides an extensive list of clinical trials being conducted internationally. The web site also lists promising therapies newly approved by the FDA.
The Center for Information and Study on Clinical Research Participation (CISCRP) is a nonprofit organization dedicated to educating and informing the public, patients, medical/research communities, the media, and policy makers about clinical research participation and the role that each party plays in the process.

Thanks for your feedback

Will I be paid for my participation?

Yes. You'll be paid for your time and participation during the study after each completed qualified visit.  The payment you receive varies from study to study, depending on its length and type.

Thanks for your feedback

What are the risks and benefits of taking part of a clinical trial?

Potential risks and benefits vary from study to study.  However, if you are interested in participating in a specific study, potential risks and benefits will be explained to you before you give your consent to participate.  You will also be able to ask questions of our medically trained staff if you have any concerns that are not addressed.

By taking part in a clinical trial, you'll play a role in helping develop the medicines of the future. This could include breakthrough treatments for Diabetes, Depression and Alzheimer’s, potentially transforming the lives of millions of people across the world.

By taking place in a clinical trial, you receive study related assessments by a Board Certified Medical Doctor, study-related medication and labs all at no cost to you. You will also receive compensation for your time and travel while in the study.

Thanks for your feedback

How do I take part?

It’s easy to volunteer. You can either click Apply to be a volunteer or call our recruitment team.

1. First you’ll speak to a member of our clinical team who will determine whether you qualify for a current clinical trial. This is based on the information you give about yourself and your medical history.

2. If you’re eligible you’ll then be invited to a screening session at our clinic with our qualified study coordinators and doctors. This will include blood and urine samples, having your blood pressure measured and having a physical examination.

3. Once your screening results are in, we’ll contact you to let you know whether or not you are eligible to take part in the clinical trial you screened for.

Thanks for your feedback

What if I fail at the screening stage?

There are all sorts of reasons why applicants don’t make it past the screening stage. Whatever the reason there’s no need to worry as we’re here to offer support and answer any questions you may have. You can ask to see if it may be possible for you to reapply as a volunteer in the future or even on another study we are currently recruiting for.

Thanks for your feedback

Why am I screened for each clinical study?

Screening is the process we use on clinical trials to see who can take part.

Clinical trials at this stage use relatively small numbers of people and therefore we need to make sure the people involved in the trial are eligible as they will provide data that can be compared and studied.

Thanks for your feedback

How long will my screening last?

Screening requirements vary with each study.  You will be advised about the requirements for a particular study when you call.  On average, a screening appointment lasts 2-4 hours.

Thanks for your feedback

What is a screening visit?

It’s reassuring to know what you can expect from your visit. During your time with us you’ll meet our staff which includes doctors and study coordinators who will take you through the following screening process:

• We’ll take a copy of your photo ID and a picture for our database when you arrive.
• Our medical team will explain the study and answer any questions you may have.
• If you agree to take part, you’ll be asked to sign a consent form before any tests are done.
• We’ll take a detailed medical and social history.
• We’ll take blood and urine samples.
• We’ll measure your blood pressure and pulse and record a heart trace.
• Once we have your results, we'll be in touch and inform you of the next steps.

Thanks for your feedback

Can I take part if I'm not on medication?

This varies for each medical trial depending on what medication you are on and the trial design.

Each clinical trial has different requirements for volunteers. Most healthy volunteer trials require just that – healthy volunteers – and therefore if you are taking long-term medication, you may not be suitable. Often if you are on short-term treatment, for example, a week of antibiotics for a throat infection, you would be able to take part once you have finished the course of medicine and the condition it was treating has cleared up.

However, research is also conducted in patient groups who may need to take medication to manage their condition. In this case it will depend on the trial requirements, but the trial will often be designed to allow patients to still take their normal medicines.

As this changes from trial to trial, please contact our recruitment team and they can discuss what clinical trials will work for you.

Thanks for your feedback

What is involved in participating in a study?

Each study has specific procedures that you will complete during each visit, each specific to the study protocol. Procedures include but not limited to blood draws, physical exams, vital sign checks and patient assessments.

Thanks for your feedback

Who can participate in a study?

The studies conducted at our clinics generally require that you are at least 18 years of age. Medical eligibility requirements vary with each clinical study. Phase II/III clinical studies require that you meet qualifying criteria determined by the study protocol - this can include restrictions on medications, recreational drug use and alcohol.

Thanks for your feedback

Thanks for your feedback

What are my responsibilities as a volunteer?

Depending on the type of study you’re volunteering for, there are certain conditions we may ask you to meet to ensure accurate trial results. These could include restrictions on exercise, smoking, medications and alcohol.  We’ll give you full details before you apply to take part in a study so you’ll always know what’s expected.

Thanks for your feedback

Can I take part in more than one clinical trial at the same time?

No. For each drug trial to provide the level of information needed to understand how a new medicine works, volunteers can only take part in one study at a time with 1-3 months in between the end of one trial and the start of another.

Thanks for your feedback

What if I change my mind?

That's no problem. Our medical trials are voluntary, so if you have a change of heart after you've applied, at the screening session or even during the clinical trial you are free to withdraw your consent. If you’ve already started the clinical trial our doctors may want you to come back for a visit, just to check that the drug is out of your system.

"The attention I received while in the clinical study was great. The coordinators were always available to answer my questions and being able to have the one on one attention for my illness allowed me to understand my situation better."

Patient H

"Dr. T is a really good and caring Doctor. I would recommend him to anyone. Very sensitive and listens really well, and cares about patients problems. The meds have been working like a charm for a year and a half now."

Patient R

"I have been seeing Dr. Thebaud for a few years now. I even moved to a different county and choose to drive to see him for care each month. I do this because I am comfortable with him treating me and don't think I could find a doctor I like closer to home. My needs were put first."
