Clinical Trial: Administration of Growth Hormone to Increase CD4+ Count in Patients Taking Anti-HIV Drugs

This study is no longer recruiting patients.

Sponsored by: National Institute of Allergy and Infectious Diseases (NIAID)
Information provided by: National Institute of Allergy and Infectious Diseases (NIAID)


This study is designed to evaluate the ability of growth hormone (GH, also known as somatropin) to increase CD4+ cell counts in patients taking anti-HIV drugs. The study is targeted toward patients with low levels of HIV who continue to have low CD4+ cell counts.

Condition Treatment or Intervention
HIV Infections
 Drug: somatropin
 Vaccine: Hepatitis A virus, inactivated
 Drug: Keyhole-Limpet Hemocyanin

MedlinePlus related topics:  AIDS

Study Type: Interventional
Study Design: Treatment, Randomized, Open Label, Active Control, Parallel Assignment, Efficacy Study

Official Title: Improving Immune Reconstitution With Growth Hormone in HIV-infected Subjects With Incomplete CD4+ Lymphocyte Restoration on Highly Active Antiretroviral Therapy (HAART)

Further Study Details: 

Expected Total Enrollment:  60

After initiation of HAART, many HIV infected patients have significant improvement in CD4+ levels. However, some patients continue to have low CD4+ counts (< 350 cells/mm3) despite adequate viral suppression. The purpose of this study is to determine whether administration of GH will increase naïve CD4+ production. Further, the study will assess whether an increase in naïve CD4+ production will lead to increases in antigen-specific CD4+ and CD8+ T cells.

Patients enrolled in this study will be randomized to one of two groups. Patients in both groups will continue their present HAART regimen for the duration of the study. Group A patients will receive daily subcutaneous injections of GH for 48 weeks. Group B participants will receive no additional therapy for 24 weeks, and will then receive daily subcutaneous GH injections during Weeks 24-28 of the study. Both groups will receive immunocyanin (keyhole-limpet hemocyanin) injections at Weeks 16 and 20 and hepatitis A vaccination at Weeks 40 and 44. At the conclusion of Week 48, all patients will discontinue GH therapy while maintaining their HAART regimen. Patients will then be followed for an additional 24 weeks.

Patients may be asked to participate in a substudy to measure the size of the thymus in people taking GH. Patients in the substudy will have a noncontrast CT scan of the chest before beginning GH therapy and again after 24 weeks of GH therapy.
