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 of a primary bone malignancy involving the lumbar spine

- Prior and/or planned concomitant medical therapy during the study period (through Day
360 post-HCT) with other bisphosphonates, Denosumab, or Teriparatide

- Pregnancy or breastfeeding - menstruating females must have a negative pregnancy test
prior to study enrollment and agree to repeat pregnancy testing and contraception use
per protocol as pamidronate is Pregnancy Category D - positive evidence of human fetal
risk based on adverse reaction data

- Renal insufficiency, defined as creatinine level greater than the upper limit of
normal for age

- Hereditary metabolic bone disease or skeletal dysplasia (e.g., osteopetrosis or OI) or
primary hyperparathyroidism

- Other indications for HCT, including Fanconi anemia, other form of inherited bone
marrow failure diseases, metabolic disorder, hemoglobinopathy, or immune deficiency

- Clinically significant fractures as defined by ISCD (a long bone fracture of the lower
extremities, vertebral compression fracture, or two or more long bone fractures of the
upper extremities) (88,89) indicated by a cast or a spine x-ray within the last 2
weeks

- Known or suspected allergy to pamidronate or related products

- Planned administration of an investigational study drug or agent that either can
interact with pamidronate or have an independent effect on bone mineral density within
the 4 weeks prior to randomization (Day 90) or planned use during study participation
(Day 90 through Day 360)

- Impending invasive dental procedure that would be expected to occur during study
participation (through Day 360)
