Further study details as provided by Tehran University of Medical Sciences:

Primary Outcome Measures:
  • To describe the percent change in the lumbar spine (L1 to L4) BMD, as measured by dual energy X-ray absorptiometry, at 12 months in patients with beta-thalassemia major undergoing allogenic BMT randomized to zoledronic acid versus placebo. [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • To describe the percent change in total hip BMD at 12 months in the two study arms. [ Time Frame: 1 year ]
  • To compare the changes in bone turn over markers at 3, 6, and 12 months in the two treatment arms. [ Time Frame: 1 year ]
  • To describe the incidence rate of all clinical fractures at 1 year in the two study arms. [ Time Frame: 1 year ]
  • To describe the general safety of zoledronic acid. [ Time Frame: 1 year ]
  • To describe the percent change in lumbar spine (L1 to L4) BMD and total hip BMD at 6 months when available. [ Time Frame: 1 year ]

Estimated Enrollment: 50
Study Start Date: November 2009
Estimated Study Completion Date: December 2011
Estimated Primary Completion Date: November 2011 (Final data collection date for primary outcome measure)

Other Name: Zometa
Placebo Comparator: Control
Patients in this arm received placebo as control group
Drug: Placebo


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Signed written informed consent.
  • Patients must be 18 years old and over.

  • Life expectancy of at least 12 months from randomization.

Exclusion Criteria:

  • Patients with any clinical or radiological evidence of existing fracture in the lumbar spine and/or total hip.
  • Patients with a history of fracture with low-density or no associated trauma.
  • Osteoporotic patients with T-score <= -2.5
  • Previous treatment with a bisphosphonate.
  • Patients with abnormal renal function as evidenced by either a serum creatinine determination 1.5 x or greater above the upper limit of normal or by a calculated creatinine clearance of 30 ml/minute or less.
  • Pregnancy and lactation.
  • Women of childbearing potential not on a medically recognized form of contraception.
  • Subjects who, in the opinion of the investigator, are unlikely to cooperate fully during the study.
  • Subjects participating simultaneously in studies with unapproved drugs, indications or treatment regimens.
  • Known hypersensitivity to zoledronic acid or bisphosphonates.
  • Patients with prior exposure to anabolic steroids, growth hormone, Parathyroid Hormone (PTH) or other drugs known to affect the skeleton (e.g., calcitonin, mithramycin, or gallium nitrate).
  • Serious intercurrent illness
  • History of metabolic bone diseases
  • History of corticosteroid treatment for other causes
  • History of antiepileptic drug treatment
  • History or surgery at the lumbosacral spine, with or without implantable devices.
  • Any disease of the spine that would preclude the proper acquisition of a lumbar spine DXA.
  • Mental illness that precludes the patient from giving informed consent.
  • Current active dental problems including infection of the teeth or jawbone (maxilla or mandibular); dental or fixture trauma, or a current or prior diagnosis of osteonecrosis of the jaw (ONJ), of exposed bone in the mouth, or of slow healing after dental procedures.
  • Recent (within 6 weeks) or planned dental or jaw surgery (e.g.. extraction, implants)
