Overview

This study aims to provide long-term follow-up care of patients previously enrolled in a vaccine study that involved poxviral vectors. Vectors are sequences of genetic material that can be used to introduce specific genes into genetic makeup. The study does not involve the use of any drug or biologic agent. Participants will undergo an annual health history. Because certain viruses enter into cells and create proteins from the viral genes, the type of vaccine treatment used is referred to gene therapy. The genes expressed by poxviral vectors do not become part of the genetic material left behind. Because gene therapy is a somewhat new technology, a prolonged monitoring of patients' health status is necessary, according to new specific reporting requirements for harmful events in patients who undergo such gene therapy studies. The risk of any long-term negative effects from the gene therapy that patients had received is quite small. Still, it is important that there be updates at least annually. This annual monitoring of health status will extend for 15 years, according to guidelines from the Food and Drug Administration, or for as long as patients are willing to participate.

Patients who received poxviral vectors (vaccinia or fowlpox, or both) at the National Cancer Institute, through a trial affiliated with the Laboratory of Tumor Immunology and Biology, may be eligible for this study.

Participants will be involved in the following forms of data collection:

  • Annual medical history and physical examinations for the first 5 years following the last vaccine.
  • Annual telephone contact during the last 10 years.
  • Health status check, including primary cancer status, secondary malignancies, neurologic disorders, autoimmune disorders, and hematologic disorders.
  • Blood tests for the presence of HIV antibodies.
  • Reporting of medical problems, including information on unexpected hospitalizations and medications.

If a participant has died, the study will document the cause of death and autopsy information if available.

Description

This protocol aims to provide long-term follow-up and continued use of research specimens of participants previously enrolled on gene transfer or other immunotherapy studies at the National Cancer Institute as well as follow-up of subjects at extramural sites receiving these agents as part of a multi-site trial. Subjects will undergo an annual health history for up to 15 years.

Eligibility

  • INCLUSION CRITERIA:
    • Subjects who received poxviral vectors (vaccinia and/or fowlpox) or other vaccines utilizing gene transfer or any other immunotherapeutic agent through GMB, UOB and LTIB affiliated trials at the National Cancer Institute, as well as subjects at extramural sites receiving these agents as part of a multi-site trial. Available stored specimens obtained from NCI participants in GMB, UOB, and LTIB affiliated protocols may be transferred to this protocol for storage and eventual future research use.
    • Subjects must be >= 18 years of age.

EXCLUSION CRITERIA:

Participants unwilling to participate.

(Please note, participants may participate in this protocol and, at the same time, participate in an active treatment or continuing care study.)

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
