Pilot Trial of Zoledronic Acid to Prevent Bone Loss in Hematopoietic Cell Transplant Recipients
Pilot Trial of Zoledronic Acid to Prevent Bone Loss in Hematopoietic Cell Transplant Recipients
Patients who undergo bone marrow transplant for different types of cancer are exposed to many
 treatments such as steroids and whole body radiation. These treatments make the transplant
 possible but also make their bones weaker and more prone to fractures which can be a source
 of significant disability and decreased quality of life for cancer survivors. Our trial will
 investigate whether giving one dose of Zoledronic acid (a commonly used drug given to
 preserve bone mass in osteoporosis) before bone marrow transplant can protect from the bone
 loss caused by the transplant procedures. The investigators are also interested in studying
 the complex interactions of bone, muscle and fat which are greatly affected after bone marrow
 transplant.
Primary Objective:

 To determine whether a single dose of zoledronic acid pre-transplant will prevent
 HSCT-related bone loss without impeding engraftment, compared with placebo.

 Secondary Objectives:

 To identify bone and muscle deficits and alterations in fat distribution prior to HSCT,
 compared with healthy controls.
Inclusion Criteria:

 -  First allogeneic HSCT

 -  Age > 18 years

 -  Ability to understand and the willingness to sign a written informed consent document.

 Exclusion Criteria:

 -  Current or prior use of bone active medication (bisphosphonates, teriparatide,
 selective estrogen receptor modulators, or Denosumab)

 -  Hypo- (Ca < 8.5 mg/dL) or hyper-calcemia (Ca > 10.5 mg/dL)

 -  Hyperthyroidism (TSH < 0.4 mIU/L and free T4 > 1.6 ng/dL)

 -  Hyperparathyroidism (PTH > 80 pg/mL)

 -  Estimated GFR < 35 ml/min/1.73 m2

 -  Other chronic disease unrelated to HSCT that may impact bone metabolism

 -  Osteoporosis: patients with a history of fragility fracture, or a Hip or Spine T score
 of <-2.5 (these patients will be treated with Zoledronic Acid and followed, but
 excluded from randomization)
