Long Term Effects On Recipients of Hematopoietic Stem Cell Transplantation

December 17, 2025 updated by: Stanford University

Longitudinal Evaluation of Recipients of Hematopoietic Stem Cell Transplantation (HSCT)

This project allows for the systematic collection and analysis of long-term follow-up clinical parameters in children who have received a stem cell transplant. The data collected will assist in determining appropriate intervention and treatment plans for patients enrolled on this study. In addition, future patients may benefit by having the ability to anticipate problems and develop methods of prevention or early intervention.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Primary Objective: Implement long-term follow-up guidelines for children, adolescents and young adults who are survivors of HSCT while establishing a database which captures the survivor's lifetime care.

Secondary Objectives:

  • Collect evidence-based data through a structured framework of periodic physical examination, laboratory and medical tests to monitor late effects in our HSCT survivors.
  • Establish standards of care for late effects of therapy post HSCT for malignant and non-malignant diagnoses.
  • Provide early identification and intervention towards recognized problems, as well as consistent education to foster a healthy lifestyle to all survivors.
  • Collect blood and tissue samples to study immune reconstitution of all immune cell types and learn more about immune reconstitution and its affect on post-HSCT complications and disease free survival.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

No older than 18 years (Child, Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Stanford Blood and Marrow Transplant clinic.

Description

Inclusion Criteria:

  • Participant is scheduled to receive OR has received a hematopoietic stem cell transplant (HSCT) for any condition.
  • Participant may have had a HSCT in another institution than Lucile Packard Children's Hospital (LPCH) yet has transferred follow-up long-term care to our institution and is being seen through the late-effects clinic from the Pediatric HSCT program.
  • Participant AND/OR parent/legally authorized representative is able to provide written informed consent and assent (as applicable) for participation.

Exclusion Criteria:

  • Participant has relapsed from a malignant diagnosis post HSCT and is not being worked-up for a new HSCT.
  • Participant or patient's authorized guardian is unable to provide consent and assent

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Collection of data and tissue samples with the goal of establishing a systematic follow-up care for HSCT recipients and a comprehensive database which can capture the particularities of survivors' clinical status through their life span.
Time Frame: This research study is expected to continue as long as we continue to perform clinical trials for children with diseases that involve the bone marrow or are affected by bone marrow production.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 1995

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
