Trial summary

Background: Gene therapy involves changing the genes inside the body s cells to stop disease. It is very closely regulated. People who have had this therapy may have problems months or even years later. Researchers do not know the long-term side effects, so they want to study people who have had the therapy.

About this study

Official title: Follow-Up Evaluation for Gene-Therapy Related Delayed Adverse Events After Participation in Pediatric Oncology Branch Clinical Trials

Background:

  • Gene therapy involves changing the genes inside the body s cells to stop disease. It is very closely regulated. People who have had this therapy may have problems months or even years later. Researchers do not know the long-term side effects, so they want to study people who have had the therapy. They want the study to continue over the next 15 years.

Objective:

  • To study over time the negative side effects from genetically engineered cellular therapy. This will be studied in people who have been in Pediatric Oncology Branch (POB) gene therapy trials.

Eligibility:

  • People who are currently or were previously in a research study with gene therapy in the National Cancer Institute POB.

Design:

  • Participants blood will be tested right before they get the genetically changed cells. They will get the cells as part of another study.
  • For the next year, they will come back to the clinic or see their doctor at home at least every 3 months. They will answer questions about their health and blood will be drawn.
  • For the next 5 years, they will go to the clinic or see their own doctor once a year. They will have physical exam and blood will be drawn.
  • For 10 years after that, they will be asked every year for health information.
  • Participants will keep their contact information up to date with researchers. They may be phoned for more health information.
  • If the participant was under 18 years old when given the gene therapy and turns 18 during this follow-up, they will be asked to sign a new consent form when they turn 18.
Read the detailed description

Background:

  • Study subjects exposed to gene therapy interventions may be at risk for delayed or longterm adverse consequences. The U.S. Food and Drug Administration (FDA) has issued Long Term Follow-up After Administration of Human Gene Therapy Products: Guidance for Industry and Testing of Retroviral Vector-Based Human Gene Therapy Products for Replication Competent Retrovirus During Product Manufacture and Patient Follow-up: Guidance for Industry, which outlines a framework to assess the risk of gene therapy-related delayed adverse events and the essential elements appropriate for the conduct of long-term follow up observations.
  • Accordingly, some vector designs (i.e. use of an adenovirus), based on duration of persistence accompanied by cumulative preclinical and clinical evidence, may require shorter periods of observation than other vector designs (i.e. use of a lentivirus).

Objective:

-To conduct long term safety evaluations for adverse events associated with genetically engineered cellular therapy in subjects who have participated in Pediatric Oncology Branch (POB) clinical trials.

Eligibility:

-Subjects who are planned to receive or have received at least one dose of a genetically engineered cellular therapy on a POB gene therapy clinical trial are eligible to participate.

Design:

  • Subjects will be evaluated for long term safety and occurrence of adverse events according to the requirements established by the FDA guidance and the NIH Guidelines for Research Involving Recombinant or Synthetic Nucleic Acid Molecules (NIH Guidelines), to include:
  • Long term follow-up after genetically engineered cellular therapy may include:
  • Post-cell infusion evaluations for T-Cell persistence (if applicable)
  • Monitoring for replication-competent retrovirus (RCR) or replication-competent lentivirus (RCL)
  • Physical examination
  • Questionnaire to detect delayed adverse events
  • Medical record review related to long term adverse events
  • To ensure adequate follow up for participants in POB receiving genetically engineered cellular therapy, a maximum accrual of 500 participants will be allowed on this study. To accommodate up to 15-year follow-up of participants, this study will remain open until 2050.

Questions about this trial

What is this clinical trial studying?

An observational study of Pediatric Cancers and Hematologic Malignancies, run by National Cancer Institute (NCI) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 3 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Conduct long term safety evaluations after gene therapy (time frame: Every 3 months X 1 year then annually X 15 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Nov 2026.
