  Purpose

The purpose of this study is to evaluate the safety of the drug oxandrolone (a type of androgen steroid) in patients with Fanconi anemia (FA), and to determine if this drug can help in the treatment of bone marrow failure in these patients. Androgen steroids are male hormones that can stimulate the production of red blood cells (the cells which carry oxygen in the blood) and platelets (cells that help blood clot).

Estimated Enrollment: 10
Study Start Date: July 2004
Study Completion Date: January 2010
Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Oxandrolone Drug: Oxandrolone
Subjects will be started on a dose of oxandrolone 0.04 mg/kg/day orally, once/day. After 16 weeks, patients will be assessed for hematologic improvement. If this criteria is not met after 16 weeks, the dose will be escalated to 0.08 mg/kg/day. If no improvement is noted after 16 weeks on the escalated dose, oxandrolone therapy will be discontinued.
Other Name: Oxandrin

Detailed Description:

The primary purpose of this study is to evaluate the safety of the drug oxandrolone in patients with Fanconi anemia (FA), and secondarily to determine if this drug can help in the treatment of bone marrow failure in these patients. It is hoped that oxandrolone will have less side effects than oxymetholone, the androgen used most frequently in the short-term treatment of bone marrow failure in FA patients. Subjects will be enrolled for approximately 18 to 30 months (12 - 24 months of treatment and 6 months additional monitoring). The oxandrolone starting dose is 0.04mg/kg/day. Study monitoring includes weekly complete blood counts, monthly serum chemistry labs, quarterly physical examinations including virilization exams and liver ultrasounds. Semi-annually, hand radiographs are obtained for bone maturation and behavioral assessments are conducted to detect any aggressive behavior or mood changes. If no improvement n the subject's blood counts are noted after 4 months of therapy, the dose will be increased to 0.08mg/kg/day for a period of 4 more months. If no improvement is noted after a total of eight months, oxandrolone will be discontinued. If the blood counts show improvement, then the drug will continue for a minimum of twelve months. Subjects may remain on study and receive a total of 24 months of therapy if they have a response in their blood counts without unacceptable side effects. Post-treatment monitoring includes blood work and ultrasound every three months, and hand radiograph at six months.

  Eligibility

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Patients must be diagnosed with Fanconi anemia that is documented by a positive test for increased chromosomal breakage with mitomycin C or diepoxybutane.
  2. At least the following peripheral blood cytopenias: (without transfusion) Absolute neutrophil count < 500/mm3 or Platelet count < 30,000/mm3 or Hemoglobin < 8.0 gm/dl
  3. Negative pregnancy test by hCG testing, if of child-bearing potential.
  4. Agreement to use a medically approved form of birth control, if of child-bearing potential.
  5. Signed informed consent by the patient or legally authorized representative.
  6. Patients must be 14 kg.
  7. Male patients will be included until the time of puberty. With the onset of puberty, they will be included until the testosterone levels reach 100 ng/dl at which time they will be excluded from the study.

Exclusion Criteria:

  1. Malignancy
  2. Concurrent enrollment in any other study using an investigational drug.
  3. Concurrent use of anticoagulants.
  4. Use of androgen therapy within last three months.
  5. Patients with severe liver disease as defined by SGOT or SGPT greater than or equal to 2.5x the upper limit of normal or total bilirubin greater than or equal to 1.5x the upper limit of normal.
  6. Patients with renal disease as defined by serum creatinine greater than or equal to 1.5 x the upper limit of normal for age.
  7. Patients less than 14 kg.
  8. Patients who have failed previous therapy with oxymetholone.
