  Purpose

The purpose of this study is to see if it is safe and effective to give HIV-positive patients L2-7001 (a type of interleukin-2) plus anti-HIV therapy. Interleukin-2 (IL-2) is a substance naturally produced by the body's white blood cells that plays an important role in helping the body fight infection. IL-2 may be able to boost the immune systems of people with HIV infection.

Primary Purpose: Treatment
Official Title: A Bridging Dose-Escalation Study of the Safety, Pharmacokinetic Properties, and Immunologic Effect of Subcutaneous L2-7001 (Recombinant Human Interleukin-2) in Patients Infected With HIV With CD4+ T-Cell Counts of 300 to 500 Cells/mm3 and Viral Burden Under 10,000 Copies/Ml on Active Antiretroviral Therapy (ART)

Estimated Enrollment: 212
Study Start Date: August 1999
Detailed Description:

This study takes place in two phases. Phase A consists of an open-label dose-escalation of L2-7001 through four dose levels. Ascending dose cohorts of five patients are studied. The safety and tolerability of L2-7001 is assessed in preparation for the second phase of the study and to estimate an MTD. Phase B involves randomization of 190 patients to (a) one of three dose levels of L2-7001 plus ART, (b) one of two dosing levels of Proleukin plus ART, or (c) ART alone. L2-7001 and Proleukin are given SC every 12 hours for the first 5 days of an 8-week cycle for three cycles. Serum IL-2 levels, soluble IL-2 receptor levels, and levels of pro-inflammatory cytokines are evaluated in 8 patients randomized to each treatment cohort of Phase B. All patients completing this phase of the protocol are eligible to be screened for enrollment in a maintenance use protocol which will allow for access to L2-7001.

Criteria

Inclusion Criteria

Patients may be eligible for this study if they:

  • Are HIV-positive.
  • Have a viral load below 10,000 copies/ml.
  • Have a CD4 count between 300 and 500 cells/mm3.
  • Have been on stable anti-HIV therapy for 4 months. Patients must be taking at least 2 drugs, 1 of which must be a protease inhibitor or a nonnucleoside drug (NNRTI).
  • Are at least 18 years old.
  • Agree to use an effective barrier method of birth control, such as condoms, during the study.

Exclusion Criteria

Patients will not be eligible for this study if they:

  • Have an AIDS-defining illness. (Patients who have had an AIDS-defining illness that was cured may still be eligible.)
  • Have an alcohol or drug abuse problem that the doctors feel would affect their ability to participate.
  • Have cancer requiring chemotherapy.
  • Have a history of autoimmune disease.
  • Have uncontrolled diabetes or certain thyroid problems.
  • Have mental illness or other serious medical condition that the doctors feel would affect their ability to participate.
  • Have received IL-2 in the past.
  • Have taken corticosteroids or certain medications that affect the immune system in the past 4 weeks.
  • Have taken hydroxyurea in the past 4 months.
  • Are pregnant or breast-feeding.
