Prevention of Bone Loss After Pediatric Hematopoietic Cell Transplantation

United States63 participantsStarted 2015-02

Plain-language summary

This is a Phase 2, open-label, randomized, controlled clinical study of pediatric subjects treated with pamidronate with calcium and vitamin D versus calcium and vitamin D alone following hematopoietic cell transplantation (HCT). The purpose of this study is to test the hypothesis that subjects receiving pamidronate with calcium and vitamin D will have higher lumbar spine bone mineral content (LBMC) measured by dual-energy X-ray tomography (DXA) at 1 year post-HCT than subjects receiving calcium and vitamin D alone (Control Group).

Inclusion Criteria: * Allogeneic hematopoietic cell transplant for hematologic malignancy (i.e. leukemia, lymphoma including ALL, AML, CML, NHL, HL) in complete remission; myelodysplastic syndrome (active dysplasia and/or blasts are permitted, but must not have active leukemia) or idiopathic severe aplastic anemia (SAA) * Non-malignant diseases including idiopathic severe aplastic anemia (SAA) and other bone marrow failure disorders, hemoglobinopathies, adrenoleukodystrophy, immune deficiencies/dysregulation disorders who will be receiving myeloablative or reduced toxicity preparative regimens that meet the following criteria: * Regimens include those that are TBI based if the TBI dose is \> 500cGy single dose or \> 800cGy fractionated, or doses \<500 cGy if combined with busulfan or treosulfan. These also include chemotherapy only based regimens that contain myeloablative doses of busulfan (\>8mg/kg) or treosulfan without TBI. * Patients with severe aplastic anemia are eligible regardless of conditioning regimen * Myeloablative preparative regimen (for SAA any conditioning therapy allowed) * Male or female ≥1 but ≤ 20 years of age at time of study enrollment * Patient or parent(s)/legal guardian(s) is able and willing to provide informed consent. Assent will be obtained per local institutional policy. Subjects who turn 18 during the course of the study will be consented at that time of their next visit by a member of the research staff. Exclusion Criteria: * History …

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
