Study of Melphalan Drug Exposure in Pediatric Hematopoietic Stem Cell Transplant Patients
An observational study of Hematologic Malignancies and Nonmalignant Diseases, run by University of California, San Francisco at 1 site in United States.
Trial summary
Melphalan is a chemotherapy drug used extensively in bone marrow transplantation. The goal of this study is to determine what causes some children to have different drug concentrations of melphalan in their bodies and if drug levels are related to whether or not a child experiences severe side-effects during their… Read more about this study

About this study
Official title: Population Pharmacokinetics (PK) of Melphalan in Pediatric Patients Undergoing Allogeneic Hematopoietic Cell Transplantation (HCT)
Melphalan is a chemotherapy drug used extensively in bone marrow transplantation. The goal of this study is to determine what causes some children to have different drug concentrations of melphalan in their bodies and if drug levels are related to whether or not a child experiences severe side-effects during their bone marrow transplant. The hypothesis is that certain clinical and individual factors cause changes in melphalan drug levels in pediatric bone marrow transplant patients and that high levels may cause severe side-effects.
Read the detailed description
Melphalan is an alkylating agent with potent antitumor and immunosuppressive properties used in conditioning regimens of pediatric allogeneic hematopoietic cell transplantation (alloHCT) to promote stem cell engraftment.
This is a single-center, prospective, non-interventional pharmacokinetics (PK) study investigating the clinical pharmacology of melphalan in 24 children undergoing allogeneic hematopoietic stem cell transplant (alloHCT) at University of California, San Francisco Benioff Children's Hospital.
Patients would receive melphalan regardless of whether or not they decide to consent to PK sampling.
Melphalan doses will not be adjusted based on PK data.
The investigators will apply the combination of a limited sampling strategy and population PK methodologies to determine specific factors influencing melphalan exposure in pediatric alloHCT recipients. Population PK methodologies support the use of sparse sampling and therefore allow us to investigate drug levels in a pediatric population that would otherwise not be feasible using traditional intensive PK sampling.
Subjects will undergo PK sampling of plasma melphalan drug concentrations over the duration of melphalan therapy (3 to 5 days).
To evaluate sources of variability impacting melphalan exposure clinical data will be obtained from the patient's medical chart on each day of PK sampling.
To assess exposure-response relationships neutrophil engraftment, treatment-related toxicity, and survival data will be collected through day 100 post-transplant.

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 4 Oct 2021.
