One of the most common questions patients ask before ever enrolling in a clinical trial is not about the study itself, but about what comes afterward: What happens at my last visit? Do I lose access to a treatment that was helping me? Will anyone tell me what the study found? And what happens to all the health information I shared along the way? Understanding the answers in advance can make the decision to participate feel less uncertain.

At our Plantation, FL research facility, led by Dr. Frank Hull, a board-certified pulmonologist with more than 20 years of pulmonary medicine and clinical research experience, every participant is walked through what to expect at study completion well before that day arrives. Specifics vary by trial and are always governed by the individual study protocol, but this guide covers the general pattern most participants can expect when a clinical trial concludes.

The End-of-Study Visit

Most clinical trials conclude with a final, formal end-of-study visit. This visit typically mirrors your earlier study visits and generally includes a review of your overall health status, a physical exam, and repeat versions of the tests performed at screening or baseline — such as lung function testing or bloodwork — so the research team can document how you are doing at the close of the study. Any remaining investigational medication or study supplies are usually collected at this time, and you will have a chance to ask final questions about your participation. The exact content of your end-of-study visit depends on the trial's protocol, so your research coordinator will let you know in advance what to expect and how long the visit will take.

Safety Follow-Up After the Trial

Many studies do not end your relationship with the research team the moment the last dose is given. It is common for a protocol to include a defined safety follow-up period — sometimes a phone call, sometimes an additional in-person visit — several weeks after your last dose or procedure, to identify any delayed side effects and complete the study's safety record.

If you experience a new or worsening symptom after your participation ends that you believe could be related to the study, contact your research team even if your formal follow-up period has already passed. Reporting a possible delayed effect helps protect your own health and contributes to the overall safety picture of the investigational treatment.

Continued Access to Investigational Treatment

Whether you can continue receiving an investigational treatment after a trial ends depends entirely on the individual study and decisions made by its sponsor. Some trials are followed by an open-label extension study, which allows eligible participants to continue receiving the treatment. In other cases, a sponsor may offer an expanded access (sometimes called "compassionate use") pathway once a study has closed, particularly if a treatment showed meaningful benefit and no approved alternative exists.

Continued access is never guaranteed and is not offered for every study. Some trials simply end, and participants return to standard, FDA-approved treatment options. Your study team will tell you, both before you enroll and again as your participation nears its end, whether continued access is a possibility for your specific trial — talk to your study team directly about your individual situation rather than assuming any particular outcome.

Transitioning Back to Standard Care

Working With Dr. Hull and Your Regular Physician

For most participants, the end of a clinical trial means returning to standard-of-care management of their condition, whether that is with Dr. Hull's practice or your own primary care physician or pulmonologist. With your permission, the research team can share a summary of your participation, including relevant test results and any safety findings, with your regular treating physician so your ongoing care reflects everything learned during the study.

If you were receiving standard-of-care treatment as part of the trial's comparison arm, this transition is typically straightforward. If you were on an investigational treatment that is not continuing, your study team will discuss appropriate next steps and treatment options with you and, when appropriate, your outside physician, so your respiratory care continues without a gap.

How Study Results Are Shared With Participants

It is important to distinguish between your own individual results and the overall results of the study. Any finding directly relevant to your personal health and safety — for example, an abnormal lab value or a clinically significant change on a breathing test — is shared with you as part of your routine care throughout the trial, not withheld until the study concludes.

The overall results of a clinical trial, however, are almost always reported in aggregate — combined, de-identified data from all participants across every study site — rather than as an individual report for each person. Because data from every research site must be collected, verified, and analyzed before conclusions can be drawn, published or publicly reported results often do not become available until months or, in many cases, years after a study's last participant completes their final visit. When results are eventually available, our office can help you find general information about a study's outcome, such as on clinicaltrials.gov.

What Happens to Your Health Data After the Study Ends

Your protected health information does not lose its protections once your active participation in a study ends. Research data continues to be handled in accordance with HIPAA, and it is typically de-identified — meaning your name and other direct identifiers are separated from the clinical data — before it is used for analysis or shared with a sponsor or regulatory authorities such as the FDA. Federal regulations and individual study sponsors set retention requirements for research records, and your information is used only for the purposes explained to you during informed consent, never for unrelated purposes.

For more on confidentiality and HIPAA protections, see our Clinical Trials FAQ and full Privacy Policy. Our research team is always available to answer questions specific to your own participation.

Who to Contact With Questions After Your Trial Ends

Your relationship with our research team does not end the moment your last study visit is complete. Patients throughout Plantation, Fort Lauderdale, Sunrise, Davie, Weston, and the rest of Broward County and South Florida can continue to reach our office with questions about their health, prior participation, or a study's status well after formal participation ends. Dr. Frank Hull and our research coordinators are familiar with your history and are available to help, even if it has been some time since your last visit.

If you are still deciding whether to enroll and want to understand the full process from start to finish, our step-by-step participant guide walks through what to expect at every stage, and our page on informed consent explains how these end-of-study details are disclosed before you ever agree to participate.

Frequently Asked Questions

Will I keep receiving the investigational treatment after the study ends?

It depends on the trial. Some studies offer an open-label extension or expanded access program for participants who tolerated the treatment well, but this is decided by the sponsor and is never guaranteed. Your study team will let you know whether it applies to your specific trial.

Will I find out my individual test results from the trial?

Results relevant to your health and safety are shared with you throughout the study as part of routine care. Overall study results, however, are typically published in aggregate rather than as individual reports, and often take months or years to become available after a trial closes.

What happens to my health information after the trial is over?

It continues to be protected under HIPAA. Research data is generally de-identified before analysis or publication, retained according to federal and sponsor requirements, and used only for the purposes described in your original informed consent.

Who do I contact if I have questions after my trial has ended?

Your research coordinator and Dr. Hull's team remain available after your study concludes. Call our Plantation, FL office at 954-520-7296 x1 with any question about your participation or health, even months after your last visit.
