Study summary

The purpose of this study is to evaluate the efficacy and side effects of donor hematopoietic cells using chemotherapy regimen without total-body irradiation in children undergoing a hematopoietic stem cell transplant for Malignant infantile osteopetrosis. The blood stem cells will be derived from either related donor or unrelated umbilical cord blood or haploidentical donor.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Diagnosis of Osteopetrosis confirm by bone and radiographic imaging
  • Age up to 5 year old

Exclusion criteria

Exclusion Criteria:

  • Carbonic Anhydrase II (CAII) deficiency osteopetrosis variant
  • ≤ 40ml/min/1.73m\^2 or RTA
  • ≥ 3mg/dL
  • ≥ 500 U/L
  • Current severe infection
  • Evidence of CNS involvement
  • Morbidity such as blindness or deafness
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 4, 2012, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
